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 can we infer from the passage?
选项 A、American stores could provide new kinds of products to the people.
B、High tech describes a technology that is not traditional.
C、State-of-the-art is not as popular as "high tech".
D、A modern plough pulled by oxen is " state-of-the-art".
答案A
解析 细节推断题。由定位句可知，“由于技术的进步，人们可以在美国商店买到许多新产品，如家用电脑、微波炉等。”选项A“美国商店可以向人们提供新产品”表达了同样的意思，故选A。其他选项文中都未提及。
