"High tech" and "state of the art" are two expressions that describe very modern technology. High tech is just a shorter way of saying high technology. And high technology describes any invention, system of device 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. A modern manufacturing 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 in American stores, such as home computers, microwave ovens, etc.
"State of the art" is something that is as modern as possible. It is a product that is based on the very latest methods and techn01ogy. 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. Every computer company claimed that its computers were "state of the art".
Computer technology changed so fast that a state of the art computer today might be old tomorrow. The expression "state of the art" became as common and popular as computers themselves. Now all kinds of products are said to be "state of the art".

Among all the fast growing science and technology, the research of human genes, or biologi cal engineering as people call it, is drawing more and more attention now. Sometimes it’s a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命)can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇帝的)family being a good example, have hereditary(遗传的)diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. Scientists just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture(生产)human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
A:Expressing the writer’s idea that gene technology will benefit people. B:Telling people the advantages and disadvantages of gene technology. C:Telling the readers that gene technology will not benefit people. D:Explaining that gene technology will also do harm to the humanity.
"High tech" and "state of the art" are two expressions that describe the modem technology. High tech is just a shorter way of saying high technology. And high technology describes any invention, system of device 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. (79) A modem manufacturing (生产) 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 in American stores, such as home computers, microwave ovens, etc.
"State of the art" is something that is as modem as possible. It is a product that is based on the very latest methods 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 modernest 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 modem way of doing something. Millions of Americans began to use the expression in the late 1970 ’ s. The reason was the computer revolution. Every computer company claimed that its computers were "state of the art".

Passage 3
| "High tech" and "state of the art" are
two expressions that describe the modem technology. High tech is just a shorter
way of saying high technology. And high technology describes any invention,
system of device 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. (79) A modem manufacturing (生产) 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 in American stores, such as home computers, microwave ovens,
etc. "State of the art" is something that is as modem as possible. It is a product that is based on the very latest methods 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 modernest electronic design and parts. It is the best that one can buy. "State of the art" is not a new expression.

and technology. Science is a method of answering{{U}} ?(51)
