题目内容

【题目】 A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine(联合) the two to do something for your local environment? It may 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 introduced by scientists. It is hoped that the new type of phone will encourage people to recycle. Scientists have thought of 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(有毒的化学物质). British researchers used the new material to develop a phone cover with a sunflower seed(种子). When this cover changes into waste, it forms nitrates(硝酸盐). These feed the seed and help the flower grow. “We have only put sunflower seeds into the cover so far. But we're trying 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 always throwing their mobile phones away. This means producers are under pressure(压力) 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(金属) and chemical waste to the environment. A biodegradable cover can reduce the harm to nature, according to the scientists. “The seed is released(释放) and the flower grows in the pot, so you don't have to worry about the phone when you have finished using it,” said Kerry Kirwan, the leader of the research team, which is based at the University of Warwick in Britain.

1Scientists did this type of research about biodegradable mobile phones in order to ________.

A.make the mobile phones more beautifulB.encourage people to recycle

2Millions of mobile phones have been sold this year and people will ______ within two years.

A.bury most of them in the gardenB.put sunflower seeds into most of them

C.take out their coverD.throw most of them away

3What does the underlined phrase “break down” mean?

A.change into chemicalsB.not workC.be dividedD.break out

4We can infer(推断) from the passage that _________.

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

B.some 650 million mobile phones have been sold within two years

C.British scientists are doing the research

D.roses perform best in this type of mobile phones

5What’s the best title of the passage?

A.the Harm to NatureB.the Developing Phone Technology

C.Phones and FlowersD.Mobile Phones and Environment

【解析】

作者是介绍一种新型环保的手机,用户用完了以后可以种植的手机,这样可以减少环境的压力。

1细节理解题。根据文中It is hoped that the new type of phone will encourage people to recycle.希望这种新型手机能鼓励人们回收利用可知,本题应该选择B

2细节理解题。根据文中Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years.今年已售出约6.5亿部手机其中大部分将在两年内扔掉可知,本题应该选择D

3词义猜测题。根据文中It looks like any other plastic, but overtime it can break down into the soil without giving out any poisonous chemicals..它看起来像其他塑料,但随着时间的推移,它会分解成土壤,而不会释放出任何有毒的化学物质可知,本题应该选择A

4推理判断题。根据文中“We have only put sunflower seeds into the cover so far. But we're trying to find out which flowers would perform best. Maybe we could put roses in next time,” said one scientist.“我们只把葵花籽放进了封面。但我们正在努力找出哪种花表现最好也许我们下次可以放玫瑰,一位科学家说。可知,这个技术还在研发中,所以本题选择C

5主旨大意题。根据文章第一段A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine(联合) the two to do something for your local environment? It may 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. 以及整篇文章的理解可知,文章主要讲述的是科学家想发明一种可以分解的手机,再不用了之后会分解成植物的一种肥料,这样就不会造成环境污染了,所以本题选择D

【题目】 In what ways has global warming affected our world? Rising sea levels, melting glaciers (冰山)and extreme weather are just a few examples.1.

Ending racial(种族的) differences

2This can force people to leave their homelands and move to other places. One result of this is gene flow (基因). This term describes the mixing of genes between populations, Scott Solomon, a biologist at Rice University in the US, told the Daily Mail

3More people will have olive(橄榄色的) or brown-colored skin. Racism could be lessened or disappear, Solomon said.

Making insects hungrier

According to Science Daily, when it is warmer, insects' body temperatures go up along with the outside temperature. This is very different from humans and other mammals(哺乳动物) ,who can keep their body temperature at a certain level without being affected by the weather.

Higher body temperatures can increase the insects' metabolism(新陈代谢

4In addition, Increasing temperatures also make insects breed (繁殖 )more quickly

Helping scientists find historic sites

5After the dry weather turned the country’s green landscape yellow, people noticed some usually pattern(图案)in the middle of a field . That’s because grass that grows above historic has a different color ang height from other grass. This helped people see the patterns.

After studying these patterns, scientists found Neolithic(新石器时代) monuments(纪念碑) and a Roman farm

A. Britain had a very dry and hot summer this year because of global warming ,the Independent reported.

B. But did you know that global warming can also bring other, less obvious long-term changes?

C. In just 125 years, there may be fewer people with dark skin or pale skin.

D. Global warming causes droughts and poor harvests.

E. This makes them hungrier, so they need to eat more.

【题目】 Do you like making paper planes? If you like origami (折纸), we're sure you enjoy making paper planes, too. All it takes is some paper and a new simple supply. And paper planes can be fun to fly around the houses or outside the yard.

No one knows for sure when the first paper plane was created. Sometimes, historians give credit to Leonardo da Vinci. However, paper folding and kite making were both popular in Asia hundreds of years ago, so it's likely that the first paper plane may have been made long, long ago.

In some Asian countries, the art of folding paper is called origami. Some people call the art of making paper planes aerogami.

Since paper planes flow (流动) through the air, they can teach scientists and engineers a lot about basic concepts of flight, engineering and aerodynamics (空气动力学) In fact, the National Aeronautics and Space Administration (NASA) (美国航天航空局) once sent a paper plane into space on a space shuttle!

If you are wondering how a paper plane would fly in outer space, you might be surprised by the answer. According to scientists, paper planes won't actually fly in outer space. Instead, paper planes would simply float in a straight line and could possibly float forever unless they hit another object!

The Wright brothers also used paper planes to test out their theories about flight before making their first flight. They built a wind tunnel and used paper planes to gain a better understanding of how their plane would operate in the wind.

So just how far can a paper plane fly? On February 28, 2012, former college quarterback Joe Ayoob set the world record for the longest paper plane flight. He threw a paper plane the entire length of a warehouse, setting the record at 226 feet, 10 inches. That broke the old record by 19 feet, 6 inches!

1The author thinks making paper planes__________.

A.is difficult activity for childrenB.has its value to flight

C.shows that the Asians are cleverD.is one of the most important discoveries

2Why did scientists send a paper plane into outer space?

A.To perform a special task.B.To observe how it would fly.

C.To help astronauts.D.To find some pleasure.

3What might make you want to know about a paper plane in outer space?

A.It would fly as we expect.B.It would not move at all.

C.It would hit another object.D.It would float in an unusual way.

4Which of the following is true?

A.Leonardo da Vinci created the first paper plane.

B.NASA once flew a paper plane in a space shuttle.

C.The Wright brothers used paper planes to test their flight theories.

D.Joe Ayoob set the world record for the longest paper plane flight at 19 feet, 6 inches.

5What is the best title for the passage?

A.The paper plane's influence on flight.

B.The history of making paper planes.

C.The invention of planes.

D.The art of making paper planes.
