Without most people realizing it, there has been a revolution in office work over the last ten years. Before that time, large computers were only used by large rich companies that could afford the investment. With the advancement of technology, small computers have come on to the market which are capable of doing the work which used to be done by much larger and more expensive computers, so now most smaller companies can use them.

The main development in small computers has been in the field of word processors, or WPS as they are often called. 40% of British offices are now estimated(估计) to have a word processor and this percentage is growing fast.

There are many advantages in using a word processor for both secretary and manager. The secretary is freed from a lot of daily work, such as re-typing letters and storing papers. He or she can use this time to do other more interesting work for the boss. From a manager's point of view, secretarial time is being made better use of and money can be saved by doing daily jobs automatically outside office hours.

But is it all good? If a lot of daily secretarial work can be done automatically, surely this will mean that fewer secretaries will be needed. Another worry is the increasing medical problems related to work with visual display units(显示器). The case of a slow loss of sight among people using word processors seems to have risen greatly. It is also feared that if a pregnant woman works at a VDU for long hours, an unborn child in her body might be killed. Safety screens to put over a VDU have been invented but few companies in England bother to buy them.

Whatever the arguments for and against word processors, they are a key feature of this revolution in office practice.

第三部分阅读理解（共20小题。每小题2分，满分40分）

　　阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

Drying food is a simple, low-cost way to keep food safe for eating. Drying removes water that small organisms use to break down food into other substances. Some of these substances may be poisonous to humans.

A device that uses the sun is a good way to dry food. There are several kinds of solar dryers. The easiest to build is called the direct dryer. The sun shines directly on the food being dried. The direct dryer is a box with holes in it so that air can enter and leave the box. It has a cover made of clear glass or plastic. When the sun shines into the box, heat is produced. The heat is trapped inside the box and cannot escape back through the cover. The heat dries the food.

The solar dryer works better if the sides of the box are black. This is because dark colors hold heat while light colors reflect it. One way to make the sides black is to use wood that has been blackened by fire.

If you use black paint instead, be sure the paint contains no lead. Lead is poisonous to people, especially children.

The box can be made of almost any material such as wood, concrete or sheet metal. The dryer should be two meters long, one meter wide and twenty-three to thirty centimeters deep. The sides and bottom should have additional material, called insulation, to keep the heat from escaping.

The surface on which the food is placed should permit air to enter from below and pass through to the food. A surface made of wires with small square openings works very well. You should use wire with the largest openings or squares that do not allow the food to fall through. Air that comes in from below the wire surface will also carry away water evaporated from the food as it dries.

A direct dryer will dry most vegetables in two-and-one-half to four hours at temperatures from forty-three to sixty-three degrees Celsius. Fruits take longer, from four to six hours at the same temperatures.

51.Solar food drying is fast, safe and low-cost. It is also healthy because nutrients such as vitamin C are kept in the food. Solar dried food also tastes and looks good.

51.In which way will the food be fried quickly?

A.Let the sun shine directly on the food.

B.Make the sides of the box black.

C.Make wood be the sides of the box.

D.The box must be made of blackened wood.

52.What does the underlined word “evaporate” in the 6th paragraph mean?

A. sink into B. change into gas or steam C. flow away D. flow into

53.According to the text., which of the following statements is true?

A.Water in the food may cause poisonous substances.

B.The sun shines into the box and be trapped.

C.Dark colours hold heat better than light colours.

D.It takes longer for vegetable to be fried.

54.What’s the text mainly about?

A.the way to dry food.

B.Solar Food Dryers

C.The device that uses the sun

D.The way to keep food safe.
