There was one thought that air pollution affected only the area immediately around large cities with factories and heavy traffic．At present, we realize that although these are the areas with the worst air pollution, the problem is really worldwide．On several occasions over the past decade，a heavy cloud of air pollution has covered the east of the United States and brought health warnings in distant areas away from any industrial cities．In fact，the very climate of the entire earth may be infected by air pollution．Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil)is creating a “greenhouse effect”—— keeping heat reflected from the earth and raising the world’s average temperature．If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York，Boston，Miami，and New Orleans will be in water．
Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature—a result that would be equally disastrous．A drop of just a few degrees could create something close to a new ice age，and would make agriculture difficult or impossible in many of our top farming areas．Today we do not know for sure that either of these conditions will happen．Perhaps，if we are lucky enough，the two tendencies will offset each other and the world's temperature will stay about the same as it is now．Driven by economic profits, people ignore the damage on our environment caused by the “advanced civilization”．Maybe the air pollution is the price the human beings have to pay for their development．But is it really worth-while?People used to think that air pollution_________ .

Plastic is everywhere because plastic is an extremely useful material. It is cheap, strong and lightweight. What’s more, it can take on nearly any form or shape, from soft and stretchy (有弹性的) to hard and glasslike.
Plastic, however, is far from perfect. It may even be bad for us. Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder (注意缺陷障碍).
Two types of chemicals in particular have raised special concern lately. They are called phthalates (邻苯二甲酸盐) and Bisphenol-A (二酚基丙烷), BPA for short. Not all plastic products contain them. But the ones that do are surrounded by controversy (争议). That’s because experts disagree on how dangerous these chemicals are.
Plastic is a single word, but plastic isn’t just one thing. What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture. Plasticizers (塑化剂) are added to plastic during the manufacturing process.
Phthalates and BPA are two types of plasticizers that work in different ways. Phthalates add softness to things like shampoo bottles, raincoats and rubber. They are also used in perfumes and makeup. BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles. BPA also appears in food and soda cans, DVDs and other unexpected places.
How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep (渗透) out of the plastic. Even though we can’t see them, we eat them, drink them and breathe them in.
Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic. Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three. California and Washington have done the same. And a number of other states are considering similar rules. As for BPA, Canada became the first country to ban the chemical from baby bottles. A dozen states are considering it.What can we know about the plastic from the first paragraph?

| C．Its importance and chemicals. | D．Its popularity and advantages. |
Which of the following products contains BPA?
| A．A soft plastic cup. | B．A pencil eraser. |

Phthalates and BPA can get into us __________.
| A．through mouth or nose | B．through blood transfusion |
| C．by feeling plastic products | D．by heating in the microwave |
What is the passage mainly about?
| A．A new ban on plastic products. | B．Problems caused by the plastic. |
| C．Good points of the plastic. | D．The use of plasticizers. |
One day when I was driving on the freeway, I noticed all the way there were large dividing walls, which had been built between it and the road running parallel to it, for noise reduction (减少) and a sense of separation. The purpose was to create a sense of privacy (隐私) for people on the other side.
This got me thinking: How often do we put up mental barriers that keep us distant from others? Lifting the artificial barriers that keep us apart can offer opportunities to express our goodwill and create better relationships. If we can do like this, maybe our life will be a little different.
There is a little post office in a nearby town, and since it is closer to me than the post office in my own town, I go there. One day, with many people jammed into the little building, a man came hurrying in to mail a letter, and the girl at the counter saw he had too little postage on it. She told him he needed 2 more cents. Obviously he was a little at a loss. He had hurried over from his office, and didn’t have any money on him or time to stand in line. He was going to run back to get the needed money and wait in line again, but he hurried to get the letter mailed in the first place.
As we were watching him, one woman volunteered a two-cent stamp, and the whole line became very quiet. It was a beautiful moment. The man hesitated for a little while and asked her if she was sure, and she assured him she was fine with giving him the stamp. He offered to go back to his office to get the two cents, and she told him not to bother.
It was a small thing, but it meant something to both of the people involved, and to the rest of us. We aren’t a yard that needs defining or a freeway that needs barriers. We are human beings who can contribute to each other’s wellbeing by taking time to pay attention and interact. After all, we are all parts of a whole living in society.The purpose of the first paragraph is to __________.
| A．summarize the main idea |
| B．give detailed information |
| C．tell readers the author’s opinion |
| D．introduce the topic |
What happened after the man being told he needed two more cents?
| A．The man went back to his office immediately. |
| B．The man turned to a lady for help. |
| C．A woman offered a stamp to the man. |
| D．The man waited in line patiently. |
What can we learn about the author?
| A．She pays too much attention to privacy. |
| B．She believes people should participate in the world around them. |
| C．She confuses real barriers with false ones. |
| D．She insists all small things always have the greatest meaning. |
Which of the following would be the best title for the passage?
| A．Artificial Barriers | B．Unnecessary Separation |
| C．An Unforgettable Experience | D．The Kindness of People |
When my brother and I were young, my mom would take us on Transportation Days.
It goes like this: You can’t take any means of transportation more than once. We would start from home, walking two blocks to the rail station. We’d take the train into the city center, then a bus, switching to the tram, then maybe a taxi. We always considered taking a horse carriage in the historic district, but we didn’t like the way the horses were treated, so we never did. At the end of the day, we took the subway to our closet station, where Mom’s friend was waiting to give us a ride home——our first car ride of the day.
The good thing about Transportation Days is not only that Mom taught us how to get around. She was born to be multimodal (多方式的). She understood that depending on cars only was a failure of imagination and, above all, a failure of confidence—the product of a childhood not spent exploring subway tunnels.
Once you learn the route map and step with certainty over the gap between the train and the platform, nothing is frightening anymore. New cities are just light-rail lines to be explored. And your personal car, if you have one, becomes just one more tool in the toolbox—and often an inadequate one, limiting both your mobility and your wallet.
On Transportation Days, we might stop for lunch on Chestnut Street or buy a new book or toy, but the transportation was the point. First, it was exciting enough to watch the world speed by from the train window. As I got older, my mom helped me unlock the mysteries that would otherwise have paralyzed my first attempts to do it myself: How do I know where to get off? How do I know how much it costs? How do I know when I need tickets, and where to get them? What track, what line, which direction, where’s the stop, and will I get wet when we go under the river?
I’m writing this right now on an airplane, a means we didn’t try on our Transportation Days and, we now know, the dirtiest and most polluting of them all. My flight routed me through Philadelphia. My multimodal mom met me for dinner in the airport. She took a train to meet me. Which was forbidden by Mom on Transportation Days?
| A．Having a car ride. |
| B．Taking the train twice. |
| C．Buying more than one toy. |
| D．Touring the historic district. |
According to the writer, what was the greatest benefit of her Transportation Days?
| A．Building confidence in herself. |
| B．Reducing her use of private cars. |
| C．Developing her sense of direction. |
| D．Giving her knowledge about vehicles. |
The underlined word “paralyzed” (in Para. 5) is closest in meaning to “_______”.
| A．displayed |
| B．justified |
| C．ignored |
| D．ruined |
Which means of transportation does the writer probably disapprove of?
| A．Airplane. |
| B．Subway. |
| C．Tram. |
| D．Car. |
You’ve just come home, after living abroad for a few years. Since you’ve been away, has this country changed for the better—or for the worse?
If you’ve just arrived back in the UK after a fortnight’s holiday, small changes have probably surprised you—anything from a local greengrocer suddenly being replaced by a mobile-phone shop to someone in your street moving house.
So how have things changed to people coming back to Britain after seven, ten or even 15 years living abroad? What changes in society can they see that the rest of us have hardly noticed—or now take for granted? To find out, we asked some people who recently returned.
Debi: When we left, Cheltenham, my home town, was a town of white, middle-class families—all very conservative (保守的). The town is now home to many eastern Europeans and lots of Australians, who come here mainly to work in hotels and tourism. There are even several shops only for foreigners.
Having been an immigrant (移民) myself, I admire people who go overseas to find a job. Maybe if I lived in an inner city where unemployment was high, I’d think differently, but I believe foreign settlers have improved this country because they’re more open-minded and often work harder than the natives.
Christine: As we flew home over Britain, both of us remarked how green everything looked. But the differences between the place we’d left behind and the one we returned to were brought sharply into focus as soon as we landed.
To see policemen with guns in the airport for the first time was frightening—in Cyprus, they’re very relaxed—and I got pulled over by customs officers just for taking a woolen sweater with some metal-made buttons out of my case in the arrivals hall. Everyone seemed to be on guard. Even the airport car-hire firm wanted a credit card rather than cash because they said their vehicles had been used by bank robbers.
But anyway, this is still a green, beautiful country. I just wish more people would appreciate what they’ve got. After a short overseas holiday, people tend to _______.
| A．notice small changes |
| B．expect small changes |
| C．welcome small changes |
| D．exaggerate small changes |
How does Debi look at the foreign settlers?
| A．Cautiously. |
| B．Positively. |
| C．Sceptically. |
| D．Critically. |
When arriving at the airport in Britain, Christine was shocked by _______.
| A．the relaxed policemen |
| B．the messy arrivals hall |
| C．the tight security |
| D．the bank robbers |
Which might be the best title for the passage?
| A．Life in Britain. |
| B．Back in Britain. |
| C．Britain in Future. |
| D．Britain in Memory. |
Many people believe Henry Ford invented the automobile (汽车). But Henry Ford did not start to build his first car until 1896. That was eleven years after two Germans developed the world's first automobile. Many people believe Henry Ford invented the production line that moved a car's parts to the worker, instead of making the worker move to the parts. That is not true, either. Many factory owners used methods of this kind before Ford. What Henry Ford did was to use other people's ideas and make them better. And he made the whole factory a moving production line.
In the early days of the automobile, almost every car maker raced his cars. It was the best way of gaining public notice. Henry Ford decided to build a racing car. Ford's most famous race was his first one. It was also the last race in which he drove the car himself.
The race was in 1901, at a field near Detroit. All of the most famous cars had entered, but only two were left: the Winton and Ford's. The Winton was famous for its speed. Most people thought the race was over before it began.
The Winton took an early lead. But halfway through the race, it began to lose power. Ford started to gain. And near the end of the race, he took the lead. Ford won the race and defeated the Winton. His name appeared in newspapers and he became wellknown all over the United States.Within weeks of the race, Henry Ford formed a new automobile company. In 1903, a doctor in Detroit bought the first car from the company. That sale was the beginning of Henry Ford's dream. Ford said: “I will build a motor car for a great number of people. It will be large enough for the family, but small enough for one person to operate and care for. It will be built of the best materials. It will be built by the best men to be employed. And it will be built with the simplest plans that modern engineering can produce. It will be so low in price that no man making good money will be unable to own one.”
The Model T was a car of that kind. It only cost $850. It was a simple machine that drivers could depend on. Doctors bought the Model T. So did farmers. Even criminals. They considered it the fastest and surest form of transportation. Americans loved the Model T. They wrote stories and songs about it. Thousands of Model T's were built in the first few years.What do we know about Henry Ford from Paragraph 1 ?
