If you want to keep healthy, you should have good habits. What is a habit? It is something we do very often. We don’t even think when we do it. It has become a part of our lives.

“Early to bed, early to rise makes a man healthy, wealthy and wise.” This is an old English saying. Do you know what it means? It means that we must go to bed early at night and get up early in the morning. If we do, we shall be healthy, rich and clever.

Is this true? Perhaps it is. We know the body must have enough sleep. Boys and girls need eight or nine hours’ sleep every day.

Some people go to bed late at night and get up late in the morning. This is a very bad habit. Then you will not think or do your work well. Of course, you can’t be healthy, wealthy or wise.

When we get up early in the morning, we can go out and do morning exercises. Exercise means doing things with the body. Walking, running jumping, swimming, and playing ball games are all exercise. If we don’t exercise, our body will become weak.

Exercise helps the blood (血液) to move around inside our body. Blood takes food to all parts of our body.

Our body also needs air to breathe. Without air, we will die. We must have lots of clean fresh air if we want to be healthy. That is why many people like to go out to do morning exercise.

From the passage we know that it is good for our health to ____ .

       A. eat a lot     B. go to bed early      C. get up late  D. go to bed late

How long should young boys and girls need to sleep a day?

       A. More than ten hours  B. Over eleven hours.

       C. Less than seven hours.      D. Eight hours or so.

What would you think if someone suggested knocking down St Paul’s Cathedral to widen the road? Or pulling down Big Ben to make way for a car park? It would be ridiculous, right? But when it comes to devastation (毀滅) of the natural world, we aren’t so easily shocked. But we should be…or we’ll be in a lot of trouble.

Nature is shrinking by the day. Ancient forests are destroyed. Wetlands are becoming dry. Woodland is disappearing, and all in the name of progress. This is bad in itself, but it’s devastating for biodiversity.

Biodiversity refers to the variety of plants, animals and other living things that are all interconnected. The ecological services provided by biodiversity are vital to everyday life. The air we breathe is a product of photosynthesis (光合作用) by green plants. Insects, worms and bacteria break down waste and make soils rich. And tiny organisms clean the water in rivers and sea. In fact, all life on the earth exists thanks to the benefits of biodiversity. More than 90 percent of the calories consumed by people worldwide are produced from 80 plant species. And 30 percent of medicines are developed from plants and animals. Maintaining a wide diversity of species in each ecosystem is necessary to preserve all living things.

The loss of biodiversity could be devastating. “It is wrong to think that biodiversity can be reduced indefinitely without threatening humans,” said Harvard University biologist Edward O. Wilson, known as the “father of biodiversity”. He warned, “We are about to reach a critical point beyond which biodiversity loss will become irreversible (不可挽回的).”

But what can we do? The present problem is that the concept of biodiversity is so vague (含糊的). People might care about giant pandas, but it is much harder to excite them about the fate of tiny sea creatures which are being boiled to death in the cooling systems of power stations along coastlines. The Guardian newspaper is trying to help. It has launched the Biodiversity 100 campaign to try to convince governments around the world to take action to deal with the widespread concerns about biodiversity. This includes persuading the UK government to create a series of marine reserves to reserve the decrease in the sea-life caused by industrial fishing, stopping fishing sharks by the Japanese fishermen and banning the killing of dingoes (wild dogs) in Australia, among many other things.

There is a lot to do. And we’d better act quickly if we don’t want to end up with a planet that can’t sustain life!

1.The writer thinks it ________ to pull down Big Ben to make way for a car park.

A.unreasonable      B.necessary         C.difficult           D.reasonable

2.The underlined sentence “Nature is shrinking by the day.” means that ________.

A.nature is badly polluted by humans

B.species are becoming fewer and fewer day by day

C.rainforests are being cut down every day

D.nature is full of mysteries

3.Edward O. Wilson thinks that ________.

A.it doesn’t matter to reduce biodiversity

B.people have done enough to preserve biodiversity

C.the situation of biodiversity is very serious

D.biodiversity loss has become irreversible

4.When it comes to biodiversity, the present problem is that ________.

A.people might not clearly know what is biodiversity and what should be protected

B.people are not aware that giant pandas are endangered

C.people don’t realize that biodiversity is vital to everyday life

D.people hunt sea creatures for food

5.What does the underlined word “It” in paragraph 5 refer to?

A.The UK government.                     B.The concept of biodiversity.

C.The action to deal with the problem.         D.The Guardian newspaper.

Lane waited on the bench nearest the bridge, as he had been instructed.. The strong wind blew straight across the river, and he had to put his overcoat closer about him.

He went over his instructions in his mind. The spy would appear at four o’clock. He would talk to Lane for a while, after which he would get up, leaving his newspapers behind. The plans would be found inside.

A distant clock began to strike the hour. As if from nowhere, a man appeared and sat down beside Lane, placing his newspaper on the seat between them. He was thin and middle-aged, and seemed in need of a good meal. He didn’t look like a successful spy, Lane thought. His talk about the weather was uninteresting.

A few minutes later he got up and continued on his way. Lane picked up the paper which lay on the bench, as if he wanted to read the news. He was excited to see the plans, stuck on the center page. At that moment, however, there was a strong gust of wind which lifted the newspaper into the air, like a kite, and blew it into the river.

1.Which of the following statement is TRUE?

    A. Sitting on the bench, Lane repeated his orders to himself

B. Lane would read about the plans in the newspaper.

C. The man Lane was expecting didn’t arrive on time

D. The man who suddenly appeared was not the one Lane was waiting for.

2.The spy was going to give Lane some important        .

    A. by the plan  B. by mistake   C. at Lane’s request   D. out of kindness

Our boat floated on between walls of forest. It was too thick for us to get a view of the land we were passing through, though we knew from the map that our river must be passing through chains of hills from time to time. Nowhere did we find a place where we could have landed: although the jungle did not actually spread right down into the river, banks of soft mud prevented us from going ashore. In any case, what would we have gained by landing? The country was full of snakes and other dangerous creatures and the jungle was so thick that one would be able to advance slowly, cutting one's way with knives the whole way. So we stayed in the boat, hoping that when we reached the sea, a friendly fisherman would pick us up and take us to civilization.

As for water, there was a choice. We could drink the muddy river water, or die of thirst. We drank the water. Men who have just escaped from what appeared to be certain death lost all worries about such small things as diseases caused by dirty water. In fact, none of us suffered from any illness as a result.

One day we passed another village, but fortunately nobody saw us. We did not wish to risk being taken prisoners a second time: we might not be so lucky as to escape in a stolen boat again.

1.What they could see on the boat was only___ .

A. high walls         B. chains of hills  C. heavy woods D. vast land

2.They couldn't land because_______ .

A. the mud on the shore was too soft      B. they could not find anyone

C. they could not find the mark on the map D. the forest was too thick to go through

3.From the passage, we can learn that_____ .

A. they were in an uninhabited area       B. they were on a journey home happily

C. the country was a civilized society    D. the country was a tropical jungle coutry

4.The best title for this passage might he______

A. I he Problem of Landing                B. Escape in the Jungle

C. An Entirely New Experience            D. Exploration of a River

18【題文】If you travel to a new exhibition at the San Francisco Conservatory of Flowers, you will have chances to see some meat-eating plants. Take bladderworts, a kind of such plant, for example. They appear so small and grow in a quiet pond. "But these are the fastest known killers of the plant kingdom, able to capture a small insect in 1/50 of a second using a trap door!"

Once the trap door closes on the victim, the enzymes (酶)similar to those in the human stomach slowly digest the insert. When dinner is over, the plant opens the trap door and is ready to trap again.

Meat-eating plants grow mostly in wet areas with soil that doesn't offer much food nutrition. In such conditions, these amazing plants have developed insect traps to get their nutritional needs over thousands of years. North America has more such plants than any other continents.

Generally speaking, the traps may have attractive appearance to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers full of nectar (花蜜).

Hair-like growths along the pitcher walls ensure that nothing can escape, and the digestive enzymes can get to work. A tiny insect can be digested in a few hours, but a fly takes a couple of days.

Some of these pitchers are large enough to hold 7.5 liters. Meat-eating plants only eat people in science fiction movies, but sometimes a bird or other small animals will discover that a pitcher plant isn't a good place to get a drink.

9.From Paragraph 1,we learn that bladderworts can__ .

A. kill an insect in a second         B. digest a fly in a few hours

C. be found floating on a quiet lake  D. capture an insect in 1/50 of a second

10.If the trap door of a meat-eating plant is closed, the plant is

A. fooling insects into taking a sip  B. producing nectar

C. tempting insects to come close     D. enjoying a dinner

11.Meat-eating plants can grow in wet and poor soil because they    .

A. can get nutrition from animals     B. don't need much food nutrition

C. can make the most of such conditions    D. have developed digestive enzymes

12.What can be captured by meat-eating plants for food?

A. A child. B. A dog.   C. A little bird.   D. A little fish.

20【題文】BUKHANNON, West Virginia~~Two rescue teams slowly moved along a two—mile path on Monday night to the site of a coal mine explosion that trapped 13 miners, who had not been heard from since the early morning accident.

Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates on the rescuers' progress.

The miners were trapped at about .6:30 and many families weren't informed of the accident until about 10 a.m.~~more than three hours after it happened. "It's very upsetting, but you've got to be patient, I guess," said John Helms, whose brother, Terry, was trapped in the mine.

The trapped miners were about 260 fee underground and about 10,000 feet from the Sago Mine's entrance, said Roger Nicholson, a lawyer from International Coal Group.

At a late night news conference, Nicholson said one team had advanced about 4, 800 feet in the four hours since entering the mine just before 6 p.m. Another team entered the mine about 30 minutes later.

He said the crew was very experienced, with some members having worked underground for 30 to 35 years. The miners were equipped with al>out one hour of breathable oxygen each. The company has not released the names of the miners.

The teams test the air about every 500 feet, and have to disconnect the power to the phones they use to communicate with the surface before doing that. "We don't want to be electrifying anything if it's in an atmospfiere with hurnahle gases," Kips said.

The cause of the explosion was not immediately known. High levels of carbon monoxide ( 一氧化物) were discovered shortly after the explosion, which delayed rescue efforts, but those levels have weakened since then, authorities said.

25.According to the passage, we ran infer that_ .

I.     communication with the trapped miners was cut off

J.    the rescue started as soon as the accident happened

K.  the two rescue teams entered the mine at the same time

L.   all the miners who were trapped underground were still alive

26.If the first team advanced at an average speed, they could dig about______per hour.

A. 1,000 feet         B. 1,200 feet       C. 2,400 feet       D. 4,800 feet

27.Where ran the passage he seen?

A. Iii a magazine.    B. In a science hook. C. On an advertisement. D. In a newspaper.

21【題文】

You wake up in the morning, the day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the drama starts. The person on tbe other end has a depressing tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. Are you still in a wonderful mood? Impossible!

Communieating with negative people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel depressed for a moment or a long time.

Life brings ups and downs, but some people are stuck in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. No wonder they can hardly win others' pity or respect.

When you communicate with positive people, your spirit stays happy and therefore more positive things are attracted. When the knife of a negative person is put in you, you have the heavy feeling that, all in all, brings you down.

Sometimes we have no choice but to communicate with negative people. This could be a co-worker, or a relative. In this case, say what needs to be said as little as possible. Sometimes it feels good to let out your anger back to the negative person, but this is to lower you to that same negative level and they won't feel ashamed of themselves about that.

Negativity often affects happiness without even being realized. The negative words of others at the start of the day can be attached to you throughout the rest of your day, which makes you feel bad and steals your happiness. Life is too short to feel negative. Stay positive and avoid negativity as much as possible.

31. Which of the following shows the position where the miners were trapped? (E: entrance P: position where the miners were trapped)

32.The purpose of Paragraph 1 is to____ .

A. make a comparison                  B. introduce a topic

C. offer an instructive story         D. tell a true story

33.How can negative people have effect on us?

A. By influencing our emotion.        B. By telling us the nature of life.

C. By changing our way of thinking.   D. By comparing their attitude to life with ours.

34.Some negative people base their happiness on —.

A. their pity for other people        B. their respect for others '

C. building up a positive attitude    D. making other people unhappy 35.According to the passage, to reduce negative people's influence on us, we are advised.

A.  to change negative people's attitude to life

B.  to show our dissatisfaction to negative people

C.  to make negative people feel as hamed of themselves

D.  to communicate with negative people as little as possible
