“High tech” and “state of the art” are two expressions that describe very modern technology(技术). High tech is just a shorter way of saying high technology. And high technology describes any invention (发明) or system that uses the newest ideas or discoveries of science and engineering.

What is high tech? A computer is high tech. So is a communications satellite(卫星). A modern manufacturing　 (制造业的)　 system is surely high tech.

High tech became a popular expression in the United States during the early 1980’s. Because of improvements in technology, people could buy many new kinds of products(产品) in American stores, such as home computers, microwave ovens (微波炉), etc. “State of the art” is something that is as modern as possible. It is a product that is based on the very latest ways and technology. Something that is “state of the art” is the newest possible design or product of a business or industry. A state of the art television set, for example, uses the most modern electronic design and parts. It is the best that one can buy.

“State of the art” is not a new expression. Engineers have used it for years, to describe the best and most modern way of doing something.

Millions of Americans began to use the expression in the late 1970’s. The reason was the computer revolution(革命). Every computer company claimed (声称) that its computers were “state of the art”.

Computer technology changes so fast that a state of the art computer today might be old tomorrow. The expression “state of the art” has become as common and popular as computers themselves. Now all kinds of products are said to be “state of the art”.

The cost of medical care in the United States is very high. The time and money that doctors spend on their medical education is probably one reason for this problem.

A visit to a doctor's office costs from 15 to 50 dollars. It's so expensive. Many people in the United States think that doctors are overpaid. However, most doctors disagree. They say that they were asked to study medicine for a long time. Tuition for many years of medical education costs a lot of money. Doctors say that it is necessary for most medical students to borrow money from the bank to pay their tuition. Because their money must be repaid to the bank, young doctors need to receive a lot of money for their work. So they charge(收费)people high prices for medical care.

Therefore the cost of medical care in America is high. Because high tuition is one cause of high costs, one way to lower costs would be to have medical school that are free or have low tuition.

1.The underlined word "tuition" in the passage means “______”

A. eating at school                   B. studying the courses

C. money used for education           D. living at school

A. a visit to a doctor's office may cost much in the USA

B. the cost of medical care is the only reason for the high costs in the USA

C. medical care in the USA costs a lot of money because doctors want to be rich

D. the high cost of tuition in medical schools is one reason for the high cost of medical care in the USA

3. The cost of medical care in the USA is very high. What does the writer think about it?

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(分解) PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can stay 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 found it while examining the structure 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 have 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 bad for humans or animals, and it is friendly to the environment. So we are thinking about putting it into wider use."

The team is now trying to make the enzyme break down PET in large quantities (大量的). “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.According to the scientists, the enzyme may solve the problem of ______ pollution.

A.air B.water C.light D.plastic

2.The researchers found that a natural enzyme helped eat plastics ______.

A.in Britain B.in the US C.in Japan D.in China

3.Which of the following 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 works better than the improved one.

D.The natural enzyme is bad for humans and animals.

4.The passage is written in a / an______ tone(语气).

A.sad B.hopeful C.angry D.crazy
