Scientists believe in the near future a new kind of car that can not only drive on the road, but also fly in the sky will serve the people, it is called “flying-driving vehicle”.

Since the turn of the 20th century, there have been many hundreds of designs for flying-driving vehicles. And some of them have actually been built and flown. But “Transition” is the closest to people.

Transition was designed in 2006, and the first road and flight tests took place in 2009. Transition is designed to really be a general airplane, which can fold up（折叠）fully its wings, drive down the road and park in a single-car garage（车库）.

Transition can climb to more than 3000 meters high. It can carry two people at speeds over 160 kilometers an hour in the air. And on the ground it can drive at highway speeds, about 113 kilometers an hour.

Scientists expect Transition to reach market at the end of 2012, at a price of around 25, 0000 dollars. Mr. Carl Dietrich says nearly 100 people have already signed up as buyers. He hopes to sell as many as 1000 a year in the near future.

1.We learn from the passage that Transition is ________.

A. a flying car         B. a helicopter         C. a high-speed plane

2.________ shows us the way of Transition driving down the road.

A.                         B.                          C.

3.According to the passage, Transition ________.

A. takes up small room

B. can park over the water

C. flies in the sky only

4.Which of the following statements is TRUE according to this passage?

A. Transition can carry 2 people at speeds over 113 km/h in the air.

B. Mr. Carl Dietrich has sold as many as 1000 Transition so far.

C. Scientists expect Transition to serve the people at the end of 2012

5.The fourth paragraph(段落) mainly tells us about the __________ of Transition.

Scientists in Britain and the United States have made a new kind of enzyme(酵素) that eats plastics(塑 料). With its help, plastics can be turned into smaller parts and go away quickly. Scientists believe that, in the future, it could solve the problem of plastic pollution.

The enzyme is able to break down PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can remain in the environment for many years and pollute large areas of land and water. So it has always been a headache to deal with the waste from PET and other plastics.

The researchers made the discovery(发 现) while examining the structure of a natural enzyme in Japan. They found that the natural enzyme was helping to break down PET plastics. So, they decided to make small changes to the enzyme by adding some amino acids(氨 基 酸). It made the natural enzyme’s plastic-eating abilities work faster and better.

John McGeehan, one of the lead researchers, said, “We’ve made an improved enzyme. It’s better than the natural one. And we are trying to make more improvements to it.” He went on, “The enzyme is not harmful to humans or animals, and it is friendly to the environment. So we are considering putting it into wider use.”

The team is now trying to make the enzyme break down PET in large quantities(大量). “We’ll see that the plastic pollution may be stopped with this technology. However, there is still a long way to go,” John McGeehan added.

1.Which is not true about the advantage of enzyme?

A.It’s able to make plastics become smaller parts.

B.It can solve the problem of the plastic pollution right now.

C.It’s used to make the plastics disappear in a rapid way.

2.The underlined phrase “break down” in the passage probably means “________” in Chinese.

A.实验 B.生产 C.分解

3.Which isn't the change they made to the natural enzyme?

A.Some amino acids were put in it.

B.The speed of plastic-eating has been improved.

C.The quality of plastic -eating remained the same.

4.Which of the following is TRUE according to the passage?

A.The scientists are still trying to improve the enzyme.

B.The enzyme will pollute large areas of land and water.

C.The natural enzyme woks better than the improved one.

5.We can’t infer from the study that________.

A.The team is able to increase the speed of the plastic -eating abilities

B.Efforts are made to increase the number of PET that the enzyme breaks down

C.Few efforts are required to the improvement of this new enzyme

Some people believe that schools will no longer be necessary in the near future. They say that because of the Internet and other new technology, there is no longer any need for school buildings, classes or teachers. Perhaps this will be true one day，but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school that is linked(链接) to libraries, museums, science centres, labs and even companies. Technological companies should create(创造) learning programs for schools. Scientists could give talks through the Internet. TV networks and local(本地的) stations could develop programs about things students are studying in school. Labs could set up Web sites to show new technology so students could see it on the Internet.

Is this a dream? No. There are already many cities where this is beginning to happen. Here the whole city is linked to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new kind of school change the usual way of learning? It is too early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will all learn something from the Internet.
