一Are you going to Guilin by plane?

一It’s fast but expensive, so I’m not sure．I ________ take a train．

A．should B．may C．must D．will

 

B

【解析】

試題分析：句意：你打算乘飛機去桂林嗎？乘飛機快但是貴，所以我不確定，我可能坐火車。must,can(could),may(maight) 可以表示猜測，must 表示肯定猜測，用于肯定句，肯定……，一定……；can’t,表示否定猜測，肯定不……，另外can(could),may(maight)，表示可能性猜測，可能……。根據(jù)I’m not sure，可知猜測的可能性比較小，故選B

考點：考查情態(tài)動詞表示猜測的用法

Since the first Earth Day started on April 22, 1970, people around the world have been encouraged to protect the environment and natural resources．Gaylord Nelson started this holiday．On the first Earth Day， 20 million people took part in Earth Day events．

Earth Day activities can include learning something about technology like cars that are more environmentally friendly and special houses that save energy and water．An organization called the Earth Day Network encourages people to use clean energy which doesn’t pollute the environment．Most of our energy comes from fossil fuels (化石燃料) that are found underground． Coal， oil and natural gas are examples of fossil fuels．Fossil fuels come from plants and animals that lived millions of years ago． Burning fossil fuels to create energy pollutes the air and water． Many scientists think that burning fossil fuels also increases the temperature of the earth． To reduce the use of fossil fuels． scientists are experimenting with hydrogen-powered (氫化發(fā)動的) cars． These cars don’t pollute the air like gas-powered cars．

Some scientists guess that by 2025, fossil fuels will run out．When people can no longer use gasoline， they may use fuel cells instead． Fuel cells use hydrogen to create energy． People do not need to worry about hydrogen running out， because it is renewable and replaceable．

In Washington， D.C.， a few people drive cars that run on fuel cells． When these cars need more energy, drivers can go to a hydrogen pump．The first hydrogen pump for the public opened in November 2004， marking an important step toward a cleaner environment．

A．Fossil fuels don’t pollute the air．

B．Hydrogen-powered cars make less pollution．

C．Many drivers are driving hydrogen-powered cars．

D．We can find many hydrogen pumps in the USA．

2.How long may people still be able to use fossil fuels?

A．Twenty years． B．Over thirty-eight years．

C．More than ten years． D．About seventeen years．

3.Which of the following is not mentioned?

A．Scientists are producing more hydrogen-powered cars．

B．Some people drive fuel-cell cars in Washington．

C．Fossil fuels come from plants and animals．

D．We can learn about environmentally friendly technology from Earth Day activities．

4.When do fossil fuels pollute the air?

A．When we use them to create gasoline．

B．When people get them from the underground．

C．After being burned to get energy．

D．After getting them from a hydrogen pump．

A TV series in England，Away from it all，has surprised everyone by becoming a success with young people across the country. Its success is surprising because the series is about the relaxing lifestyles of people who live in the country. There is none of the action that we usually see on TV today. There are also no stressful moments, busy offices or crowded cities. Away from it all is set in the peaceful English countryside and tells simple stories about people’s kindness.

The director of the TV series says that its success is a sign of teenagers suffering from stress. They say that watching Away from it all helps teenagers forget about the pressures of exams and homework, and the troubles that fill the world today. They also say that it’s a good sign of today’s young people turning to happier TV series as it shows they want a happier and healthier world.

Although the series’ success might have a good side, many teachers and parents are worried, however. They say that some of their students and children spend more time before TV and are using Away from it all as an excuse for not finishing homework. Some children have even refused to learn for exams because they say that they can only get personal happiness by avoiding stressful situations.

And what do the experts say? Paula Ray, a doctor of education, says that TV can influence children’s lifestyles. But she says that if a child reacts strongly, it’ s likely that there are other reasons for his change in behaviour. She says that there is nothing wrong with watching Away from it all but suggests that parents should let their children know TV is not the same as real life.
