Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed.
There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to eliminate them.
Different products, processes and activities of our industrialized world together form the major source of pollution. The forms of pollution can be mainly divided into three kinds—solid, liquid and gas.
These pollutions have greatly damaged our planet and continue to do so. In fact, pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.
We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the danger of pollution and so on.
The earth is our home and we have the duty to take care of it for ourselves and our later generation. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. Laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.

While Jennifer was at home taking an online exam for her business law class, a monitor（監控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone number they once used.
Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.
小題1:Why was Jennifer watched in an online exam?

A．To correct her typing mistakes.

B．To find her secrets in the room.

C．To prevent her from slowing down.

D．To keep her from dishonest behaviors.

小題2:The underlined expression cutting edge in Paragraph 3 is closest in meaning to______.

A．advanced technique	B．sharpening tool
C．effective rule	D．dividing line

小題3: For Internet universities, exams and diplomas will be valid if _____.

A．they can attract potential students	B．they can defeat academic cheating
C．they offer students online help	D．they offer many online courses

小題4:Some programs can find out possible cheaters by _____.

A．checking the question answering speed

B．producing a large number of question

C．scanning the Internet test question

D．giving difficult test question

小題5: Which of the following is the best title of this passage?

A．The Advantages of Online Exams

B．The High-tech Methods in Online Courses

C．The Fight against Cheating in Online Education

Sometime early in the next century, human beings will move to Mars. They will live there for about a year, and then will be replaced with another group of pioneers. Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.
We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures. These resemblances have caused many people to consider a centuries-long project: to terraform Mars. Terraforming means altering a planet’s surface so that Earth’s life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists.
Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth. But it will take at least 300 years.
Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt. The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support. Our very existence and numbers are threatening many other species. We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate. Currently terraforming earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places.
While the possibility of such a project is small, it is not impossible .Even if earth –bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth.
The future existence of all the people in our world may very well depend upon our ability to terraform Mars.
小題1:What would be the best title for this passage?

A．Terraforming Mars.	B．Saving the Earth
C．Travelling to Mars.	D．A Newly-found Place

小題2:What does the underlined word “altering” mean in the second paragraph?

A．Warming.

B．Changing.

C．Planting.

D．Building

小題3:According to the passage the main purpose of terraforming Mars is to ________.

A．do some scientific research work

B．find out its similarity to earth

C．avoid the dying away of many other species

D．find on Mars living place for the increasing human beings

小題4:The main reason for causing many people to consider terraforming Mars is that _______.

A．there are some resemblances between Earth and Mars.

B．terraforming Mars is theoretically simple

C．we have had some experience with terraforming our own planet: Earth

D．the development of science and technology is very rapid

小題5:What’s the author’s attitude towards the project?

A．Optimistic.	B．Negative
C．Sceptical（懷疑的）	D．Objective.

Japanese students work very hard but many are unhappy. They feel heavy pressures(壓力) from their parents. Most students are always told by their parents to study harder and better so that they can have a wonderful life in the future. Though this may be a good idea for those very bright students, it can have terrible results for many students who are not gifted(有天賦的) enough. Many of them have tried very hard at school but have failed in the exams and have their parents lose hope. Such students felt that they are hated by everyone else they meet and they don’t want to go to school any longer. They become dropouts.
It is surprising that though most Japanese parents are worried about their children, they do not help them in any way. Many parents feel that they are not able to help their children and that it is the teachers’ work to help their children. To make matters worse, a lot of parents serif their children to those schools opening in the evenings and on weekends — they only help the students to pass the exams and never teach them any real sense of the world.
Many Japanese schools usually have rules about everything from the students’ hair to their clothes and things in their school bags. Child psychologists(心理學家) now think that such strict rules are harmful to the feelings of the students. Almost 40% of the students said that no one had taught them how to get on with others, how to tell right from wrong and how to show love and care for others, even for their parents.
小題1:“Dropouts” are those who _______.

A．make troubles in and out of schools

B．go about or stay home instead of being at school

C．try hard but always fails in the exams

D．lose hope and give up some of their subjects

小題2:According to the passage, it’s necessary to teach students _______.

A．how to study well	B．how to get on with others
C．to show love and care for others	D．All above

小題3:Which of the following can be the best title of the passage?

A．The Trouble in Japanese Schools

B．The Problems of Japanese Students

C．Education in Japan

D．The Pressures on the Students in Japan

People diet to look more attractive．Fish diet to avoid being beaten up，thrown out of their social group，and getting eaten as a result．That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists．
　　The research team have discovered that subordinate(低一等的) fish voluntarily diet to avoid challenging their larger competitors．"In studying gobies we noticed that only the largest two individuals，a male and female，had breeding（繁殖）rights within the group，" explains Marian Wong．"All other group members are nonbreeding females，each being 5-10% smaller than its next largest competitor．We wanted to find out how they maintain this precise size separation．"
　　The reason for the size difference was easy to see．Once a subordinate fish grows to within 5-10% of the size of its larger competitor，it causes a fight which usually ends in the smaller goby being driven away from the group．More often than not，the evicted fish is then eaten up．
　　It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish．Whether they did so voluntarily，by restraining how much they ate，was not clear．The research team decided to do an experiment．They tried to fatten up some of the subordinate gobies to see what happened．To their surprise，the gobies simply refused the extra food they were offered，clearly preferring to remain small and avoid fights，over having a feast．
　　The discovery challenges the traditional scientific view of how boss individuals keep their position in a group．Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves，so keeping their competitors small．
　　While the habits of gobies may seem a little mysterious，Dr．Wong explains that understanding the relationships between boss and subordinate animals is important to understand how hierarchical（等級的）societies remain stable．
　　The research has proved the fact that voluntary dieting is a habit far from exclusive to humans．"As yet，we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature，" the researchers comment．"Data on human dieting suggests that，while humans generally diet to improve health or increase attractiveness，rarely does it improve long-term health and males regularly prefer females that are fatter than the females' own ideal．"
小題1:When a goby grows to within 5-10% of the size of its larger competitor，it _________．

A．leaves the group itself	B．has breeding rights
C．eats its competitor	D．faces danger

小題2:The underlined words "the evicted fish" in Paragraph 3 refer to _________．

A．the fish beaten up	B．the fish driven away
C．the fish found out	D．the fish fattened up

小題3:The experiment showed that the smaller fish _________．

A．fought over a feast	B．preferred some extra food
C．challenged the boss fish	D．went on diet willingly

小題4:What is the text mainly about?

A．Fish dieting and human dieting．	B．Dieting and health．
C．Human dieting．	D．Fish dieting．

In 1883. John Roebling was inspired by an idea to build a spectacular bridge connecting New York with the Long Island. However, bridge building experts throughout the world thought this was an impossible feat and told Roebling to forget the idea, but Roebling could not ignore the vision he had in his mind of this bridge. After much discussion and persuasion he managed to convince his son Washington, an up and coming engineer, that the bridge in fact could be built.
The project started well, but when it was only a few months underway a tragic accident on the site took the life of John Roebling. Washington was injured and left with a certain amount of brain damage, which resulted in him not being able to walk or talk or even move.
"We told them so." "Crazy men and their crazy dreams.'' "It's foolish to chase wild visions." Evcryone had a negative comment to make and felt that the project should be scrapped since the Roeblings were the only ones who knew how the bridge could be built. In spite of his handicap, Washington was never discouraged.
One day he was lying on his bed in hospital, seeing the sky and the tops of the trees outside for just a moment with the sunlight streaming through the windows, and a gentle breeze bowing the flimsy white curtains apart when an idea hit him. He decided to make the best use of the only finger he could move. Thus, he slowly developed a code of communication with his wife.
He touched his wife's arm with that finger, indicating to her that he wanted her to call the engineers again. Then he used the same method of tapping her arm to tell the engineers what to do. It seemed foolish but the project was under way again.
For 13 years Washington tapped out his instructions with his finger on his wife's arm until the bridge was finally completed.

Google, the Internet search and mapping company, has developed a car that can steer without a driver.
Sometimes the reality is stranger than science fiction: Google is road-testing cars that steer, stop and start without a human driver. The goal is to “help prevent traffic accidents, free up people’s time and reduce carbon emissions.” says Sebastian Thrun, who is the project leader for the driverless car, or Carbot.
By developing the car and the software that drives it, Google wants to change how people get from place to p1ace. Eric Schmidt, one of the company’s top officials, said, “Your car should drive itself. It just makes sense.”
So far, the driverless autos have gone about 140,000 miles on California roads without people taking over the driving. Many of the roads are very busy or full of curves that challenge human drivers. The autos’ software makes it possible to know speed limits, traffic patterns and road maps. The vehicles use radar, lasers and video cameras to find other cars and avoid people crossing streets.
There has only been one accident during the testing. And in that case, the Carbot was hit from behind by a human driver when Goog1e’s car was stopped at a red light. Engineers say the driverless cars are safer than autos with people behind the wheel because the computers react much more quickly than humans.
The Carbot is still in very early testing stages. Experts agree that it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the driver’s seat of a driverless car. When the auto was first invented it was called a “horseless carriage”. Now it seems that it is time for the “driverless carriage” to be part of our 1ives.
小題1:What’s the main idea of the passage?

A．An auto revolution is on its way.

B．Google has developed a driverless car.

C．The Carbot has passed its early testing stages.

D．Science fiction has turned into reality.

小題2:The driverless car is safer than an auto with people because _______.

A．it uses radar, lasers and video cameras

B．it knows speed limits, traffic patterns and road maps

C．the computer has a better sense of direction than drivers

D．the software responds to emergencies faster than a human driver

小題3:The advantage of the Carbot is that _______.

A．it can drive all by itself

B．it can avoid any traffic accident

C．it doesn’t pollute the environment

D．it is the most fashionable car nowadays

小題4:70. The author’s attitude towards the Carbot is _______.

A．unfriendly

B．desperate

C．critical

D．optimistic

Personal Air Travel
The idea: flying cars
Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people.
You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car.
Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down.
Flying for Fun
The idea: Jet Packs
The idea was a hit when a stuntman (特技演員) flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful.
You’ll be able to use the equipment－roughly the size of two scuba tanks fastened to your back－for short journeys.
They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping.
Taxis
The idea: driverless taxis
These computer-controlled taxis will take you wherever you want along a fixed route, whenever you want to go.
For the price of one person’s bus fare, several people can ride at speeds of up to 25 mph, and there will be fences to guard against accidents.
There will be little, if any, wait for the use of the taxis, which will leave from stations and will be used by prepaid cards.

Babies understand what their mothers say, even when they speak a language their children have never heard before, scientists claim.
The researchers found that one-year-olds reacted in exactly same way to their mothers’ voices regardless of whether they were speaking English or Greek, showing what mothers have long known – that babies pick up on tone of voice rather than the words themselves.
The researchers, from Cardiff University’s School of Psychology, observed babies as they watched their mothers perform actions with toys using the English words “whoops” and “there”. The scientists studied reactions from one-year-old babies to their mums’ voices even when they were speaking both English and Greek, and keeping the same tone of voice. The academics found that babies reproduced the same reactions regardless of whether they knew the language.
Study leader Dr Merideth Gattis of Cardiff University’s School of Psychology says, “What this work showed was that children could have access to understanding simply through tone of voice. We did ‘whoops’ and ‘there’ in two languages and got exactly the same results.” The research, published in the journal Cognitive Development, was conducted on 84 babies aged between 14 and 18 months, over the course of a year, with none of the babies having any previous exposure to Greek.
Dr Gattis says that children respond to tone clues in their parents’ voices from an early age.
She says, “Tone of voice is a really useful signal of what someone is thinking. We never have direct access to other people’s minds, except the signals in language that they give out.” She says the study shows that it is less important what parents say than how they say it.
Dr Gattis adds, “A child may ask if you like his / her drawing, for example. You might say yes, but if you don’t sound enthusiastic, the meaning may not get across.” Before children begin to speak, parents should use exaggerated tone when speaking to them.
小題1:According to the text, what have mothers long-known?

A．Babies have a better understanding of English.

B．Babies pick up on tone of voice.

C．Babies like their mothers’ performances.

D．Babies like drawing from an early age.

小題2:Which of the following is TRUE, according to the study?

A．Tone of voice is the most useful sign of what someone is thinking.

B．After children begin to speak, tone becomes unimportant.

C．The babies acted the same way regardless of the language.

D．The research was conducted on 48 babies.

小題3:According to the text, Dr. Gattis believes that _________.

A．we have no access to other people’s minds

B．babies can’t understand what “yes” means

C．parents should always sound enthusiastic

D．how a parent speaks is more important than what he or she says

小題4:What’s the text mainly about?

A．The content of the journal Cognitive Development.

B．The famous works of Dr. Gattis.

C．Babies understanding their mothers through tone.

D．Babies having the potential to learn language well.

小題5:The text can be classified as _________.

A．a report
