PART V READING COMPREHENSION [25 MIN]

In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer. Mark your answers on Answer Sheet Two.

TEXT A

Do you realize that every time you take a step, the bones in your hip are subjected to遭受forces between four and five times your body weight? 81 When you are running, this force is increased further still. What happens if through disease a hip-joint ceases to be able to resist such forces? For many years hip-joints and other body joints have been replaceable either partially or completely. It is after all a simple ball and socket joint球窝关节; it has certain loads负荷imposed on施加it; it needs reliability over a defined life; it must contain materials suitable for the working environment. 82 Any engineer will recognize these as characteristic of a typical engineering problem, which doctors and engineers have worked together to solve, in order to bring a fresh lease of life to people who would otherwise be disabled.

B 推断81. According to the passage, when would most weight be imposed on hip-joints髋关节?

A. When one is walking.

B. When one is running.

C. When one is standing.

D. When one is lying down.

A细节82. Engineers regard the replacement of hip-joints as a(n) ____ Problem.

A. mechanical

B. medical

C. health

D. agricultural

1. the bones in your hip are subjected to遭受forces between four and five times your body weight.

are subjected to遭受

2. It is after all a simple ball and socket joint球窝关节; it has certain loads负荷imposed on 施加it;

socketn. 插座；窝，穴；牙槽vt. 给…配插座

sock n. 短袜；一击vt. 重击；给……穿袜adv. 正着地；不偏不倚地adj. 非常成功的imposed on：impose restriction on施加限制impose punishment on them施加处罚impose themselves on硬缠着impose fines on someone罚款impose rules on members给会员订立制度impose resctrictions on施加限制impose sanctions on对；实施制裁impose fine on sb向某人征收罚款

This typifies the way in which engineers work to help people and create a better quality of life. The fact that this country has the most efficient agricultural industry in the world is another good example. 83 Mechanical engineers have worked with 84 farmers and biologists to produce fertilizers, machinery and harvesting systems. 84 This team effort has now produced crops uniformly waist high or less so that they are better suited to mechanical harvesting. Similar advances with other crops have released people from hard and boring jobs for more creative work, whilst machines harvest crops more efficiently with less waste. Providing假如more food for the rapidly increasing population is yet another role for the mechanical engineer.

The peacock typifies pride. 孔雀象征骄傲。
