I think there are several reasons that suggest developing robots is a waste of money.

In San Diego recently $325,000 was spent on inventing a robotic squirrel to do some scientific experiments. The research proved that squirrels are able to scare away snakes by wagging (摇动) their tails. Do you need a robotic squirrel to work this out?

What about AIBO, a robotic pet, developed in Japan? In Japanese aibou means “buddy”. These pets have been developed at huge cost mainly to provide entertainment. They've been used in movies and music videos. Universities have used them for educational purposes. However, in 2006 the company stopped producing these robotic pets in order to save money. Was it worth a lot of money?

Then there’s NAO, a robot which has been developed by a French company. Its main purpose is to make life easier for humans. It speaks 19 languages and has its own personality. It can tell children a story, help in the classroom or the home, or act as a companion to those people who need someone to be with. A fully developed one costs $16,000. Is that value for money? Who can afford it anyway?

There may be good reasons why it is worth developing robots, but so far I haven’t thought of any.

1.What does the underlined word “companion” in Paragraph 4 mean in Chinese?

A.公司 B.机构 C.对手 D.伙伴

2.What is the true fact about the robots mentioned?

3.What does the writer think of developing robots?

Health experts say the U.S. adult now sits about 6.5 hours a day. That is up about an hour a day compared to 2007. The news is even worse for teens. They sit eight hours each day. The information was put out by the National Center for Health Statistics. It has collected the numbers for the past 16 years. It is worried about what it has found.

Scientists in Britain and the United States have made a new kind of enzyme(酵素)that eats plastics. 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 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 plastic­eating 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(大量地). “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.完成句子：

With the help of this new enzyme, plastics can be________________ smaller parts and go away quickly.

It's a common belief that fish can't remember anything for longer than seven seconds. It may seem sad to think that every moment in their lives would be like seeing the world for the first time. But don't be so quick to feel sorry for them. A new study has found that fish have much better memories than we used to think.

In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They took the fish out and then waited for 12 days before putting them back in the tank again. They found that after such a long break the fish sill went to the same place where they first got food.

In fact, scientists had been thinking for a long time that African cichlids might have a good memory. But there was no clear evidence until the latest findings.

Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. "If fish are able to remember that a certain area contains(容纳) safe food, they will be able to go back to that area without putting their lives in danger," lead researcher Trevor Hamilton told Live Science.

So next time you are watching your pet fish from outside the tank, perhaps you should feel close to them-they may remember who you are.

1.We often feel sorry for fish because __________.

A.they have bad memories B.they can't remember anything

C.they are often used for research D.every moment in their lives is new

2.Why did the researchers carry out the research?

A.A kind of fish food. B.A kind of hiding place.

C.A container for holding water. D.A container for keeping fish.
