【题目】 The FDA is the common name for the Food and Drug Administration (食品药品监督管理局). It is a government agency that makes consumer goods safe. It regulates(调节) food and the food supply. It also controls diet supplement(供给). The FDA also makes sure that drugs and medical instruments are safe and effective.

For drugs and medical machines to be accepted, they must go through a certain process. There are many strict tests. First, anything that humans use must be tested on animals. This may take up to 6 years. Then, it must be tested with a few people. Testing on 15 to 20 people can last up to a year and a half. Third, a mid-sized group (100 to 500 people) is used. This often takes two years. Then a large group is tested over 3 years. Of 5,000 drugs discovered, only 5 go to the final test. Of that, only one passes on to the market.

Food supplements like ginseng(人参) follow a different path. The FDA does not test them as they do for drugs. The agency only controls these products if they are unsafe but are already being sold. Two exceptions are baby and medical food. Because those that use them are not strong, the FDA is more careful with these products.

Labeling(标签) is a major focus. A label must show what a product is for. For drugs, labels should say the name of the drug and what it is used for. It should also detail who should take it and list any side effects. It needs to detail directions for pregnant women, children, or old people. It also needs to detail safety information.

The FDA protects the public from harm. It achieves this through controls and labeling. It has standards for effectiveness in medical products. It also has standards for how information is shared.

【1】According to the passage, how many drugs make it to the market?

A.Nearly five thousand.B.One of five thousand.

C.Five of five thousand.D.Over five thousand.

【2】The writer uses food supplements as an example of which of the following?

A.Things the FDA avoidsB.Things the FDA controls

C.Things the FDA buysD.Things the FDA refuses

【3】What do we know about labeling from paragraph 4?

A.It is a necessary way to protect the public.

B.It does not matter if people read the labels or not.

C.It is only good if people can find the label.

D.It has no use if doctors tell people what to do.

【4】Which of the following best shows the structure of the passage?

A.B.C.D.

【题目】 Your grandparents miss you very much, so you’d better go to visit them _____.

【题目】

In 1845, a deadly disease struck the farms of Ireland, killing all the Lumper potato plants. In another place or time, the death of single crop species (物种) might not have been so important. But in Ireland, in 1845, people depended almost solely on the patato for food. The death of one species caused a terrible famine(饥荒). Now, some scientists are worried that such a famine could happen again, but on a much wider scale.

Over the centuries, farmers have discovered thousands of different species of food crops. Each species has special qualities. Some can be grown in very hot or cold climates. Others are not affected by certain diseases. However, you won’t find many of these species in your local supermarket. To feed the seven billion people on Earth, most farmers today are growing only species of plants and farming only species of animals that are easy to produce in large numbers.

For example, in the Philippines, there were once thousands of varieties of rice: now fewer than 100 are grown there. In China, 90 percent of the wheat varieties grown just a century ago have disappeared. Scientists believe that over the past century, we have allowed more than half of the world’s food varieties to disappear.

One solution to this problem is to collect and store the seeds (种子) as many different plant varieties as we can before they disappear. The idea was first suggested by Russian scientist Nikolay Vavilov. In the 1920s and 1930s, he collected around 400,000 seeds from five contients. More recently, others are continuing the work he began.

In the U.S. state of Iowa, Diane Ott Whealy wanted to protect historic plant varieties, like the seeds her great –grandfather brought to the U.S. from Germany more than a hundred years ago. She and her husband started a place called Heritage Farm, where people can store and trade seeds.

More importantly, the people at Heritage Farm don’t just store the seeds; they plant them. By doing this, they are reintroducing foods into the marketplace that haven’t been grown for years. These food species are not just special in terms of appearance or taste. They also offer farmers food solutions for the future, from the past.

【1】What is this passage mainly about?

A. The need to protect different food species.

B. How to increase the number of food species.

C. The fact that many food species are dying out.

D. How to prevent food species from disappearing.

【2】Why are some scientists worried that such a famine could happen again?

A. Because people depend on certain species of food crops.

B. Because the same deadly disease may attack crops again.

C. Because the world’s population is larger than that in 1845.

D. Because farmers grow the same potatoes as those in the past.

【3】The following sentence would best be placed at the end of _______________.Meanwhile, thousands of other species are dying out.

A. Paragraph 1B. Paragraph 2C. Paragraph 3D. Paragraph 4

【4】What can we learn from the passage?

A. The disease spread very quickly and killed thousands of people in Ireland.

B. Around 80 percent of the rice varieties in the Philippines have disappeared.

C. People have been storing seeds to save plane varieties for less than 100 years.

D. Heritage Farm is the first place in the U.S. for people to store and trade seeds.

【题目】Ｗill there be more people in 100 years ,do you think so ?

A. No, there isn’t B. Yes , there will be C. No, there won’t D. Yes, they will
