I will tell you the truth about plastic bags-the positive and the negative sides and provide a solution to this problem. Whether it is a shopping bag, a food bag or a trash bag, they are all made of plastic bags. Grocery store owners are very generous in using plastic bags. They place the fruit in one bag and drop the box of milk in another. Ever wonder why?
The positive side of plastic bags
Grocery stores, shopping centres, and restaurants are not thrifty in using and giving out plastic bags because they cost no more than a cent each, while a paper bag costs four cents. Plastic bags are produced so cheaply and massively(大量地)that they are used by 80% of store owners. In addition, they are light and very easy to carry and store.
The production of plastic bags has increased greatly over the last 20 years and producers of plastic bags are making large profits. However, the negative side of plastic bags is becoming well-known. More people are now getting worried that the earth is becoming a victim of the plastic bag success story.
The negative side of plastic bags
While production and consumption(消費)of plastic bags is good for business, it is not so for our Mother Earth. They have resulted in an increase in the amount of litter found floating in water or in the streets where we live.
Plastic storage bags, after usage, usually go to landfills(垃圾填埋地)as trash bags. They make the oceans poison sea animals. They give off toxins(毒素)when burned. They simply pollute the ground, air and water.
That is the true cost of plastic bags, and it looks like it is more than a cent. These are very alarming concerns and proper action needs to be taken.
小題1:According to Paragraph 3, plastic bag producers ________.
A.are now worried that the earth will become a victim of plastic bags
B.don’t think they have done enough to popularize plastic bags
C.have not realized the harm of plastic bags
D.have succeeded in popularizing the use of plastic bags
小題2:From the last three paragraphs, we learn that         .
A.plastic bags harm the earth severely
B.most plastic bags are not made use of
C.the prices of plastic bags are reasonable
D.plastic bags are the leading polluter on the earth
小題3:What will the writer most probably talk about in the following paragraph?
A.How plastic bags are produced.
B.How plastic bags are used.
C.How to popularize the use of paper bags.
D.How to solve the problems caused by plastic bags.

Teenagers at one German school are learning how to achieve happiness alongside other traditional   35  such as maths and languages.
The class sits in a circle with their eyes shut and they count from one to ten: someone starts, the   36  voice comes from the far right, a third from the other side.
The aim of the game is to   37  for an opportunity to shout out the   38  without clashing (相撞) with another voice or leaving a pause. On the first try,  39  of the young Germans try to be first, while a few are too shy to join in. But by the fifth   40  , they develop a rhythm (節奏) . The message gives other people space but also claims your own. This is a requirement for social well-being.
Unlike schools in other nations, German schools do not usually have school sports teams or seek to build school spirit. Many teens admit they are   41  and confused, but school is not usually the place to find relief.
The Willy Hellpach School in Heidelberg is the first in the nation to develop a happiness   42  It is   43  for 17-19years old students to prepare for university entrance exams. "The course isn't there to make you happy," Ernst Fritz-Schubert, the school principal, warned pupils, "   44  rather to help you discover the ways to become happy. "
Cooking a meal together will be one of the class   45  , along with improving body language under the   46  of two professional actresses.
The course is taught for three periods a week. Despite the happy subject, the pupils themselves insist it is no laughing matter.
"In the first period, we had to each say something   47  about another member of the class and about ourselves. No laughing at people or teasing," said Fanny, 17.
The message is that self-esteem (自尊) improves   48  too.
Research by the school shows it is not the first to start happiness classes and they also exist at some US universities, but are mainly based on positive thinking, using   49  from studies of depression.
"That would be too one-sided for us. We want to show how decent (好的) food or exercise can help too," the principal said.

Although man has known asbestos (石棉) for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H.W.Johns, owner of a New York City Supply Shop for roofers, was responsible for the opening of that first mine.
Mr.Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands.How astonished the customers were to discover that he was not burned at all.You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport them from Italy to the United States, Mr.Johns sent out a young scientist to seek a source nearer home. This young man found great vein(巖脈), in the province of Quebec in Canada.
Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen.When it is mined, the asbestos is heavy, just as you would expect a mineral to be.When it is separated, a strange thing happens: the rock breaks down into fine, soft, soapy fibres.
Scientists do not know why the rock can be separated easily into threads, but they have found thousands of uses of this fireproof material, of the so-called “cloth of stone”.
小題1:Which title best expresses the main idea of this passage?
A.Asbestos mined in Canada B.Fireproof matter
C.A “wonder” mineral D.A new roofing material
小題2:Johns proved his ability as a salesman by_______.
A.going into roofing businessB.carrying asbestos from Italy
C.sending a trained scientistD.showing the use of asbestos gloves
小題3:Which is the most important characteristic of asbestos that the author wants to show us?
A.It is like thread.B.It feels soapy.
C.It burns easily.D.It is unusually heavy.
小題4:The author’s main purpose in writing this passage was to _______.
A.show the need for more scientists
B.compare asbestos with other minerals
C.increase the sales of asbestos
D.present facts about asbestos

About 97% of the world's water is salty and is found in our oceans and seas. But, as we can't drink seawater, how can it be important?
Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important seawater is!
Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced.
The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn't matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.
Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important seawater is!
小題1:People used to think that the rubbish thrown into the sea ________.
A.wouldn't harm the fish in the sea
B.would change the balance of the food chain
C.would be broken down in the sea
D.wouldn't do much harm to the sea
小題2:From the passage, we learn that ________. 
A.most fish and sea animals live at the surface of the seas
B.it is very difficult to break the balance of a food chain
C.excessive fishing has caused the decrease in fish stock
D.it won't be long before the problems concerning oceans will be solved
小題3:Which of the following is NOT a way being used to protect oceans?
A.The use of international agreements.
B.Forbidding fishing to protect fish stocks.
C.The use of new techniques.
D.Raising people's awareness of the need to protect oceans.
小題4:What would be the BEST title of the passage?
A. The importance of seawater.
B. Life in the oceans.
C. How to protect food chains.

New genetic analysis has revealed that many Amazon tree species are likely to survive human-made climate warming in the coming century, contrary to previous findings that temperature increases would cause them to die out. A study,   1  in the latest edition of Ecology and Evolution, reveals the   2  age of some Amazonian tree species -- more than 8 million years -- and   3  shows that they have survived previous periods as warm as many of the global warming imagined periods   4  for the year 2100.
The authors write that, having survived warm periods in the past, the trees will   5  survive future warming, provided there are no other major environmental changes.   6  extreme droughts and forest fires will impact Amazonia as temperatures   7 , the trees will stand the direct impact of higher temperatures.

The study disagrees with other recent researches which predicted tree species’ extinctions   10  relatively small increases in global average air temperatures.
Study co-author Dr Simon Lewis (UCL Geography) said the   11  were good news for Amazon tree species, but warned that drought and over-exploitation of the forest remained major   12  to the Amazon’s future.
Dr Lewis said: “The past cannot be compared directly with the future. while tree species seem likely to   13  higher air temperatures than today, the Amazon forest is being transformed for agriculture and   14 , and what remains is being degraded by logging, and increasingly split up by fields and roads.
“Species will not move as freely in today’s Amazon as they did in previous warm periods, when there was no human   15 . Similarly, today’s climate change is extremely fast, making comparisons with slower changes in the past   16 .”
“With a clearer   17  of the relative risks to the Amazon forest, we   18  that direct human impacts -- such as forest clearances for agriculture or mining -- should remain a key point of conservation policy. We also need more aggressive   19  to reduce greenhouse gas emissions in order to make minimum the risk of drought and fire impacts and   20  the future of most Amazon tree species.”

Is language, like food, a basic human need? Judging from the extreme experiment of Frederick in the 13th century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue he told the nurses to keep silent.
All the babies died before the first year. But clearly there was more than language deprivation (剝奪,喪失). What was missing was good mothering. Without good mothering, in the first year of life especially, the ability to survive is seriously affected.
Today no such extreme deprivation exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to signals of the baby, whose brain is programmed, to mop up language rapidly. There are critical times, it seems when children learn more rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again.
Linguists suggest that speech milestones are reached in a fixed order and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ.
Recent evidence suggests that a baby is born with the ability to speak. What is special about man’s brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a teddy bear with the sound pattern “teddy bear”.
But speech has to be developed, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child’s babbling, clinging, grasping, crying, smiling, and responds to them. Insensitivity of the mother to these signals reduces the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child’s nonverbal (非語言的) signals is basic to the growth and development of language.
小題1:Frederick’s experiment was extreme because _________.
A.he wanted to prove children are born with ability to speak
B.he wanted his nurses to say another language
C.he was unkind to the nurses
D.he ignored the importance of mothering to the babies
小題2:The reason that some children are backward in speaking is most likely that _________.
A.they do not listen carefully to their mothers
B.their mothers do not respond to their attempts to speak
C.their brain has to absorb too much language at once
D.their mothers are not intelligent enough to help them
小題3:In paragraph 3, by “critical times” the author means _________.
A.difficult periods in the child’s life
B.moments when the child becomes critical towards its mother
C.important stages in the child’s development
D.times when mothers often neglect their children
小題4:If a child starts to speak later than others, he will _________ in future.
A.have a high IQB.be less intelligent
C.not necessarily be backwardD.be insensitive to verbal signals
小題5:If the mother seldom responds to her child’s signals, _________.
A.the child will be able to speak properly
B.the child will continue to give out signals
C.the child will invent a language of own
D.the child will make little effort to speak

“Why should I care about the environment?” some people ask. There is a very simple reason: We live on the earth, and it is the only place we can live on right now, as we cannot live in space yet. If we treat the earth like a garbage dump, it will become dirty and unlivable. If we treat it well by being eco-conscious, the earth will stay clean and suitable for living, for ourselves and for our children.
What is “being eco-conscious”?
Being eco-conscious means being aware of your actions, and what you do to the environment. For example, you might think, “Using hairspray is great for fixing my hair.” However, if you are eco-conscious, you would ask, “Does this hairspray have CFCs in it? Could I be destroying the earth by using hairspray?”
How can I be eco-conscious?
You can find many simple ways to help the environment in your everyday life.
When you go shopping, bring a bag or a basket with you. Please try not to use plastic bags as much as you can.
You can go to work by bike or on foot if it is not far from your home.
You can put your rubbish into different bags, which makes it convenient for recycling.
You can eat less chewing gum.
You can use your own chopsticks instead of the disposable ones in your company or in restaurants.
You can put batteries in a special box instead of in garbage bins.
You can use the water which has been used for washing vegetables or fruits to clean the floor and the toilet or to water your garden.
You can turn off the decorative lights in your room when watching TV.
You can turn down your air conditioner by one degree, as this will cause a 10% reduction in energy use.
You can use recycled paper. Every ton of recycled office paper saves 380 gallons of oil. You can also use recycled glass instead of glass made from raw materials. This will reduce the related air pollution by 20%, and the related water pollution by 50%.
Please believe that. If you do a little, it will make a big difference.
小題1:Human beings should care about the environment because _________ .
A.if we make the earth unlivable, we’ll have to live in space
B.it can help our children live better
C.if we don’t, the earth will become a garbage dump
D.it will help to make the world a good living place
小題2:If your deskmate is an eco-conscious person, he should __________.
A.be aware of the importance of protecting the environment
B.use plastic bags when he buys something
C.know nothing about CFCs
D.turn his air conditioner to a higher degree
小題3:If you want to help the environment, you should do all the following EXCEPT ________.
A.share a car with your colleagues
B.use paper bags instead of plastic bags
C.use hairspray containing CFCs
D.use recycled glass instead of glass made from raw materials
小題4:It can be inferred from the passage that _________.
A.it’s very hard for human beings to keep the earth clean and comfortable
B.protecting the environment is the duty of everybody
C.we should protect the environment together, as it’s no use doing it individually
D.it’s very easy to be eco-conscious
小題5:According to the author, which of the following statements is WRONG?
A.Being eco-conscious means you should know much about the environment.
B.The more we care, the better the environment will be.
C.If each of us just does a little, we can’t make any difference.
D.If we treat the earth badly, we’ll make a lot of trouble for ourselves.

She had been shopping with her Mom in Wal-Mart. She must have been 6 years old, this beautiful brown haired, freckle-faced image of innocence. Outside, it was pouring so heavily.
We all stood there just inside the door of the Wal-Mart. We waited, some patiently, others annoyed because nature messed up their hurried day. I got lost in the sound and sight of the heavens washing away the dirt and dust of the world.
Her voice was so sweet as it broke the hypnotic trance (昏昏欲睡) we were all caught in. “Mom, let’s run through the rain,” she said.
“ No, honey. We’ll wait until it slows down a bit.” Mom replied.
This young child waited about another minute and repeated, “Mom, let’s run through the rain. ”
“We’ll get soaked if we do,” Mom said.
“ No, we won’t, Mom. That’s not what you said this morning,”  the young girl said as she tore at her Mom’s arm.
“This morning? When did I say we could run through the rain and not get wet?”
“Don’t you remember? When you were talking to Daddy about his cancer, you said, If God can get us through this, he can get us through anything!”
The entire crowd stopped dead silent. I dare say you couldn’t hear anything but the rain. We all stood silently. No one came or left in the next few minutes. Mom paused and thought for a moment about what she would say.
Now some would laugh it off and scold her for being silly. Some might even ignore what was said. But this was a moment of affirmation in a young child’s lifetime when innocent trust can be developed so that it will bloom into faith. “Honey , you are absolutely right. Let’s run through the rain. If get wet, well maybe we just need washing.” Mom said. Then off they ran.
We all stood watching, smiling and laughing as they rushed past the cars and they held their shopping bags over their heads just in case. They got soaked. But they were followed by a few who screamed and laughed like children all the way to their cars. And yes, l did. I ran. I got wet. I needed washing.
You may lose your material possessions, your money and even your health, but no one can ever take away your precious memories. So don’t forget to make time and take the opportunities to make memories.
小題1: Which of the following is the closest in meaning to the underlined word “affirmation”?
A.happinessB.loveC.disagreementD.approval
小題2: What do we know about the mother in the story?
A.Her husband was cured of his cancer.
B.She was strong-willed and considerate.
C.She was in despair and pretended to forget what she said.
D.Her daughter completely understood the situation her family was in.
小題3: Which of the following may the author agree with?
A.The mother should not tell her child about the family misfortune.
B.Parents should act more bravely than their children.
C.Parents should grasp every opportunity to influence their children to grow well.
D.Children should learn to show gratitude and understanding to their parents.

A long time ago, before human beings lived on the earth, little coral polyps(水螅)settled around tropical (熱帶的)coastlines and constructed corals. Over a long period they created lots of reefs. Yet, pollution, climate change and commercial fisheries are limiting the chance of future generations knowing or seeing many of the reefs and sea creatures that exist. Hence, take action to dive now and you can explore the underwater world.
Commercial underwater diving began in ancient Greece. Diving in general means that the whole body is completely in water. On that account there are lots of exciting and quite adventurous ways to dive, like shark cage diving, scuba diving(戴水肺潛水)and reef diving.
There are great coral reefs all over the world, but usually they are situated in warm, clear water such as the Pacific and the Indian Ocean, where they grow best. This is why there are no coral reefs on the west coast of South Africa. However, South Africa’s east coast offers much brightly coloured sea life.
In South Africa more than 100,000 dives a year are made just in coral reefs, which are one of the natural wonders of the world. To see the whole beauty of the reef the right diving gear(設備) is an essential requirement. This means a perfect fitting diving mask and fins, as well as a snorkel(呼吸管)and a friend. Diving alone is dangerous because there may be strong currents you are not aware of, and it’s a lot more fun to share the experience with someone. However, before you can explore the deeper sea, a certificated and checked scuba, a wetsuit and of course a license will be needed. Whether you choose the snorkel or the scuba to spot the colourful underwater world, try to touch as little as possible, be careful with the corals and don’t strike the fishes, because the complex ecosystem is very sensitive.
小題1:The following factors probably affect coral reefs EXCEPT ________.
A.sea creaturesB.pollutionC.fishingD.climate change
小題2:Which of the following is true according to the passage?
A.Human beings appeared before corals were created.
B.One needs a license to dive into the deeper sea.
C.Diving alone has many advantages.
D.The origin of diving is in modern Greece.
小題3:There are no coral reefs on the west coast of South Africa probably because of a lack of ________.
A.large waters and soft sand
B.warm currents and delicious food
C.friendly creatures and flat seabed
D.clear water and suitable temperature
小題4:The last paragraph mainly tells us ________.
A.diving alone under the sea is rather dangerous
B.some matters we need pay attention to when diving
C.South Africa is a popular place for diving
D.what we should wear when diving
