If you are planning to study in the United States, you need to consider several factors. Everyone has different opinions about where is the best place to live in. Also, the best places to live are not always home to the best schools. Finally, many schools specialize in different areas of study. The Massachusetts Institute of Technology, for example, is a great school for computer science and technology-related fields of study. However, if you want to study oceanography（海洋学）, your interests may be better served by attending school in a place that is on a coastline or near the ocean.

Now I am sure that you know which schools are considered the best in the country. So I will tell you about which states I believe are the best to live in.

California is a nice state. Northern California specifically has very good weather. Los Angeles in Southern California is another story though. Life in Los Angeles is full of excitement and fast, and sometimes dangerous. As for me, I enjoy the time I spent in Massachusetts, Virginia and Maryland and these states have a lot of history and culture. The weather is not as perfect as California, but it is still quite nice. My favorite area of America is the Mid-west. Middle America, I think, is home to the true American sense of values. In addition, there are many good universities there.

Also, you need to think about your likes and dislikes and then research the various states. You like sunshine and hate snow? Then you probably won't like the Midwest or even the Northeast. Open space, nature and peace and quiet? Then you probably should stay away from America's large cities. Are you interested in government? Then Washington D.C. is the only place for you. Whatever you decide, put some thought into it. The place you live could be the difference between a great study-abroad experience and a state of great suffering on earth.

1.From the first paragraph we can conclude （得出结论）that in the USA _______.

2.What should be considered first if you want to study in the USA?

3.From the third paragraph we can find that _______.

4.If you study in Middle America, you can probably _______.

5. From the last paragraph of this passage we can get to know that _______.

The trade fight between the United States and China increased Monday as the two economic superpowers　 hit　 each　 other　 with　 their　 biggest　 round　 of　 tariffs　 ( 关 税 )　 yet.　 The　 Trump administration added new 10% tariffs on $200 billion of Chinese goods just after midnight ET (noon in Beijing), coveringing thousands of products, including food seasonings, baseball gloves, network routers and industrial machinery parts. China fired back immediately with new taxes of 5% to 10% on $60 billion of US goods such as meat, chemicals, clothes and auto parts. The moves lead to the growing conflict between the world’s top two economies.

“We are squarely in the midst of the ‘it’ll get worse before it gets better’ phase,” Aninda Mitra, senior analyst at BNY Mellon Investment Management, said in a note after the latest tariffs were announced last week.President Donald Trump’s waves of new tariffs on China now apply to over $250 billion of Chinese goods, roughly half the amount the country sells to the United States. The latest　 round affects　 thousands of　 products　 bought　 by　 US　 consumers, including　 hundreds　 of millions of dollars of furniture and electronics imports　　 (电子进口). The US tariffs added earlier in the year mostly hit industrial goods.

The measures are meant to punish China for what the Trump administration says are unfair trade practices, such as intellectual property (知识产权)　　 theft.

Beijing has rejected ( 拒 绝 )　 the US　 assertions ( 断 言 ), accusing the　 United States of protectionism and bullying. It has fired back with tariffs on American goods worth more than $110 billion.

The Trump administration has made “false accusations” and sought to “add its own interests on China through great pressure,” the Chinese government said in a lengthy white paper published Monday about the two countries’ trade relationship, according to state news agency Xinhua. Unbelievably, The latest round of US tariffs is set to increase at the end of the year from 10% to 25%. China hasn’t yet spelled out how it will respond to that.

Trump has also threatened ( 威胁) tariffs on another $267 billion of Chinese products. That would mean the US measures effectively cover all China's annual goods exports ( 出 口 ) to the United States (the total for 2017 was about $506 billion).

China, which imports a far smaller amount from the United States, is running out of new products to target, but analysts say it still has other options to fire back. They include charging even higher tariffs, adding import quotas, limiting Chinese citizens’ travel to the United States for study and tourism, and reducing taxes for companies affected by the tariffs.

1.We can infer from the first two paragraphs that __________.

A. the Trump administration added new 10% tariffs on $200 billion of Chinese goods

B. China fired back taxes of 10% on US goods in total

C. Chinese goods sold to America amounts to about $500 billion

D. the latest round affects thousands of products bought by US consumers, mostly including industrial goods

2.According to what The Trump administration says, the measures are meant to punish China because of _________.

A. protectionism　　 B. bullying

C. intellectual property theft　　 D. furniture

3.Chinese government will take some measures against America in trade fight EXCEPT _______ .

A. threaten tariffs on another $267 billion of Chinese products

B. charge even higher tariffs

C. limit Chinese citizens’ travel to the United States

D. increase taxes for companies affected by the tariff

4.Where is the passage most likely to be from?

In the United States, 30% of the adult population has a “weight problem”. To many people, the cause is obvious（明显的）: they eat too much. But scientific evidence does little to support this idea. Going back to the America of the 1910s, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically（体力上）, walked more, used machines much less and didn’t watch television.

Several modern studies, moreover, have shown that fatter people do not eat more on the average than thinner people. In fact, some investigations（调查）, such as the 1979 study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer people.

Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts:

The more the men ran, the more body fat they lost

The more they ran, the greater amount of food they ate.

Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

1.The physical problem that many adult Americans have is that ______.

A. they are too slim                  B. they work too hard

B. Of course, there is some evidence to show this is true.

C. There is hardly any scientific evidence to support this.

The United States Department of Agriculture has a program called Wildlife Services.Its job is to help protect agriculture and other resources from threats and damage by wildlife.Often that means helping farmers deal with unwelcome visitors.This organization has experts from different fields and it has set up thousands of inquiry agencies all over the country where farmers can explain their difficulty and get practical help.

One example from Wildlife Services of its work involved a farmer in Washington State,in the Pacific Northwest.Several years ago,thousands of Canada geese landed on his fields.The geese began to eat his carrot crop.Biologists from the program suggested that the farmer use noise-making devices and other measures to scare the large birds away.These efforts apparently succeeded,which made the farmer quite happy.

Wildlife Services also has a livestock(牲畜)protection program.The program just offers suggestions to keep those unwelcome visitors away instead of killing them.Experts suggest providing secure shelter for chickens,sheep and other animals that could be attacked.They also suggest using lights above places where animals are kept.And they advise people who see coyotes around their property to chase them away by shouting,making loud noises or throwing rocks.For home gardeners,a two-meter fence might help keep out deer.To keep out rabbits,a wire fence has to be only about a half-meter high.It should extend fifteen centimeters underground to keep rabbits from digging under it.If snakes are a problem,remove dead trees and cut high grass to destroy their hiding places.And to protect livestock,consider using guard animals such as dogs and donkeys,which are very effective.Due to its effective work,ever since the Wildlife Services was started,it has been well received by farmers all over the States and neighboring countries such as Canada and Mexico.

The United States government has decided that food from cloned(克隆) cattle, pigs and goats is safe to eat. The Food and Drug Administration also says it found no risks in meat and milk from cloned animals.

The F.D.A. looked at studies for several years before it announced its decision in a final report this month. The United States Department of Agriculture supported the findings. But it says time is needed to clear the way for marketing meat and milk from clones.

The F.D.A. will not require any product to be registered(注册) as coming from clones. A producer would need to label (标注) a product “clone-free”. The agency (机构) says that could be misunderstood because the food is not different from other food.

But activists argue that the F.D.A. based its decision on incomplete research into possible risks. The Center for Food Safety criticized the use of studies supplied by cloning companies. Animal rights activists point out that cloning attempts often fail. They say cloning is cruel and can lead to suffering.

Congress (国会) has been trying to get the F.D.A. to do more studies. But the agency noted that experts in New Zealand and the European Union had come to the same findings about the safety of food from clones. Japan, South Korea and Taiwan say they want to study it further before taking action.

Products from cloning may not be widely used for several years. Clones cost much , which is why they are not widely used for feeding. The Agriculture Department says few clones will ever become food. Their traditionally raised animals would enter the food supply instead.

1.What is the best title for this passage?

A. Is Food from Cloned Animals Safe?

B. A New Clone Policy

C. A Big Danger —Cloned Food

D. Cloned Products —A　 Terrible Choice

2.All the following are sure of the safety of cloned products EXCEPT _________.

A. New Zealand　　　　 B. Japan

C. the USA　　　　　 　 D. the European Union

3.Why are products from cloning not widely used for feeding?

A. Because cloning attempts often fail.

B. Because they are not safe to eat.

C. Because cloning is cruel.

D. Because they are expensive.

4.Where can you probably see the passage?

A. In a novel.　　　　　　　　　　 B. In a newspaper.

C. In a travel leaflet.　　　　 D. In a　 notice　 on the wall.

The private automobile (私家车）has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid transportation, the automobile has freed them from having to live near their place of work. This has encouraged the growth of the cities, but it has also led to traffic problems.

For farm families the automobile is very helpful. It has made it possible for them to travel to town very often for business and for pleasure, and also to transport their children to distant schools.

Family life has been affected（影响）in various ways. The car helps to keep families together when it is used for picnics, outings, and other shared experiences. However, when teenage children have the use of the car, their parents can’t keep an eye on them. There is a great danger if the driver has been drinking alcohol or taking drugs, or showing off by speeding or breaking down traffic laws. Mothers of victims（受害者）of such accidents have formed an organization called MADD (Mothers Against Drunk Driving). These women want to prevent further tragedies (悲剧）. They have worked to encourage the government to limit the youngest drinking age. Students have formed a similar organization, SADD (Students Against Drunk Driving) and are spreading the same message among their friends.

For many Americans the automobile is a necessity. But for some, it is also a mark of social position and for young people, a sign of becoming an adult. Altogether, cars mean very much to Americans.

1.Which of the following is NOT mentioned in the text?

A. Cars have encouraged the growth of the cities.

B. Cars can bring families together when they go for picnics.

C. Cars have enabled people to live far from their place of work.

D. Cars help city families to transport their children to faraway schools.

2.What has been done to deal with the problem of drunk driving?

A. Parents have paid more attention to their children.

B. Some organizations have been set up against drunk driving.

C. Mothers have tried to persuade their children not to drink alcohol.

D. University students have asked the government to solve the problem.

3.We can infer from the text that 　　　　　 in America.

A. it will be more difficult for people to get new cars

B. parents will not allow their children to have their own cars

C. the government will encourage people to use public transportation

D. cars will still be popular though they have caused many problems
