A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower.

A biodegradable (生物可降解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage consumers to recycle. Scientists have come up with a new material over the last five years. It looks like any other plastic, but overtime it can break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this cover turns into waste, it forms nitrates (硝酸盐). These feed the seed and help the flower grow. “We’ve only put sunflower seeds into the cover so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time.” said one scientist.

As phone technology is developing so quickly people are constantly throwing their mobiles away. This means producers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists. “The seed is released and the flower grows in the pot so you don’t have to concern yourself with the phone when you have finished using it,” said Kerry Kirwan, the leader of the research team.

After you have finished using the new type of mobile phone, _______.

A. the sunflower seed will come out and flower in the pot

B. the phone cover will break down very soon in the soil

C. it will be recycled by the producers

D. it can charge itself with electricity in a green way

This type of research is done because ________.

A. the technology of making phones is changing rapidly

B. too many waste mobile phones may lead to environmental problems

C. nobody has ever thought of recycling mobile phones

D. producing mobile phones uses a lot of energy

We can infer from the story ________.

A. the new type of mobile phones are already on the market

B. the new type of mobile phones will sell extremely well

C. the material of the new type of phones is harmful

D. other flowers may be used in the new type of mobile phones

The best title of this passage is           .

A. Recycling our phones

B. The phones that flower

C. A new material for making phones

D. The harm of thrown-away phones

More than 10 years ago, it was difficult to buy a tasty pineapple. The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1996, the Del Monte Gold pineapple produced in Hawaii first hit our shelves.

       The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the outside and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world’s best-selling pineapple variety, and delivering natural levels of sweetness in the mouth, up until then only found in tinned pineapple.

       In nutrition(营养) it was all good news too. This nice-tasting pineapple contained four times more vitamin C(维生素C) than the old green variety. Nutritionists said that it was not only full of vitamins, but also good against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.

       Seeing the growing market for its winning pineapple, Del Monte tried to keep the market to itself. But other fruit companies developed similar pineapples. Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market.

We learn from the text that the new type of pineapple is ______.

   A. green outside and sweet inside         B. good-looking outside and soft inside

   C. yellowy-gold outside and hard inside    D. a little soft outside and sweet inside

Why was the new type of pineapple selling well?

   A. It was rich in nutrition and tasted nice.    B. It was less sweet and good for health.

   C. It was developed by Del Monte.         D. It was used as medicine.

The underlined word “fixture” in Paragraph 3 probably refers to something ______.

   A. that people enjoy eating             B. that is always present

   CV. that is difficult to get                     D. that people use as a gift

We learn from the last paragraph that Del Monte ______.

   A. allowed other companies to develop pineapples

 B. succeeded in keeping the pineapple for itself

   C. tried hard to control the pineapple market

   D. planned to help the other companies

A cheap drug that can stop bleeding in people recently injured in an accident could potentially save the lives of tens of thousands worldwide, a new study says.

  Researchers studied the effects of tranexamic acid (凝血酸), or TXA, in more than 10,000 injured people in 40 countries who received the drug within 8 hours of being injured. The study was published in the medical journal Lancet. Doctors found that patients who got TXA had a 15percent lower chance of dying from hemorrhage than those who didn’t get it . They also had a 10 percent lower chance of dying from any other cause, including organ failure and a head injury. The study was paid for by the British government.

  The drug is commonly used in wealthy countries during elective surgeries(外科手术) to stop bleeding , but isn’t used for accident victims. TXA is off-patent and made by many companies. It costs about $4.5 per gram, and a typical dose is two grams. It is usually given via an injection(注射) and would be relatively easy to introduce, even in poor countries, experts said.

  Previous tests of the drug regarded its use in elective surgeries, such as heart operations, but this was the first study to test the drug on accident victims. Doctors were worried it might increase side effects such as blood clots (凝块)in the heart and lungs, strokes, or heart attacks. There was no evidence of that in the Lancet study, though the authors said it was possible they might have missed some of these incidents.

  For people between 5 and 45, accidents are the second leading cause of death worldwide after AIDS, and about 600,000 injured patients bleed to death every year. Experts estimated that if TXA were readily available, between 70,000 and 100,000 lives a year could be saved. Though the drug wasn’t tested on children , experts said it would almost certainly work with them as well.

The underlined word” hemorrhage” in Paragraph 2 probably means ________

 A. serious illness    B. heart disease     C. heavy bleeding   D. lack of drug

What can we learn about TXA from the passage?

 A. It can only be made in England     B. It was only used in operations before

 C. It is a patented drug              D. It is mainly used in poor countries

Doctors were worried about using TXA because ________

 A. a lot of patients died unexpectedly after using it

 B. it has no treatment effect on patients

 C. it can cause blood clots or stroke

 D. they hadn’t used it on accident victims before

What do we know from the last paragraph?

 A. It is a pity that TXA wasn’t widely used on injured patients before

 B. Tests have proved that TXA can be used on children

 C. People between 5 and 45 should be injected with TXA every year

 D. Accidents are the first leading cause of death worldwide.
