问题     "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 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. 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 common and popular as computers themselves. Now all kinds of products are said to be "state-of-the-art".  
What is the purpose of the passage?
选项 A、To tell how "high tech" and "state-of-the-art" have developed.
B、To give examples of "high tech".
C、To tell what "high tech" and "state-of-the-art" are.
D、To describe very modern technology.
答案C
解析 主旨判断题，可用排除法选择最佳答案。文章一开始就指出两个词组都形容非常先进的技术，然后下面对两个词组作了详细的介绍，故选C。选项A是一个很强的干扰项，文章只是分别介绍了两个词组的涵义、使用领域、使用时间等，并未讲述演变的历史，故排除。选项B只是文章中的细节，而选项D表达的是两个词组的意思，不是文章的写作目的，是偷换概念。
