There is a very simple way of measuring the height nfa water-tower, which we can-not measure by climbing. Suppose, for example, that we wish to find out the height of the water-tower, AB, in a factory. We first of all go to where the water-tower is stand lng and measure a distance of, say 90 feet from it, in a straight line, marking the spot that is 90 ft from the water-tower. Then we take a stick. CD, and stand it in the ground at the spot we have just marked.

Let us suppose the stick we’re using is 4 ft in height. We now walk farther away from the water-tower in the same straight line as we measured off the distance of 90 ft. We go from the watchtower until we come to a point E, where with our heads on the ground we see the top of the stick and the top of the water-tower in the same straight line-that is, the top of the stick just covers the highest part of the water-tower.

We now have two triangles (三角形) and the proportion (比例) of the side CD to the side CE in the smaller triangle. CDE. is exactly the same as the proportion of the side BA to the side BE in the larger triangle BAE. It is clear from this that every scbool boy or school girl can work out the height of the water-tower.

Suppose that the line CE is 5 ft. We know that the stick is 4 ft high and the length BE is 950. From these measurements we have the simple proportion sum (算题) S is to 4 as 95 is to AB.

Trees and other high buildings, of course, can he easily measured by using the same way.

3. 　Which of the following statements is NOT true?

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.

1．从第一段partly because it is different in so many ways...可知。2．此题为事实理解属。在冰岛的几天中，没有提到D项。3．从第三段可知Since Iceland is located just under the Arctic Circle, there is no darkness in summer and no daylight in winter。4．从第四段可知。5．此句童为“宁可无鞋，不可无书”，说明冰岛人把书看得十分重要。

“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 technol-ogy describes any invention, system or 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 　(制造业的) 　system is surely high tech.

High tech become a popular expression in the United States during the early 1980’s. Pk, cause of improvements in technology, people could buy many new kinds of products 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 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 televi sion 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 de-scribe the best and most modern way of doing something.

Millions of Americans hegan to use the expression in the late 1970’s. The reason was the computer revolution. 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”.
