I hope you dont think I ve forgotten you. There have been so many places to see and so many things to do that
30、 Ive not had much time for writing letters.I shall soon be starting my studies at Kings College. So far Ive been learning about England and British ways of living. I wont tell you about London. There are plenty of books you can read and plenty of pictures you can look at. Im sure youll be more inter
31、ested to know what I think about the life here.I find some of the customs(风俗)new and interesting. People here do not shake hands as much as we do in Europe.

A working la
34、boratory model of a new system of radar that makes use of a beam of light is said to be ten thousand times more accurate than the best comparable system of radar that uses microwaves.The model has shown that this radar system, known as laser-dopple radar, can measure with absolute precision speeds v
35、arying from spaceship orbital injection(进入)velocities(速度)of five miles per second down to virtual stops-speeds of less than one-thousandth of an inch per second. According to the scientists who are developing this system, such fine measures of velocity are of prime importance in space missions. In a
36、 rendezvous(对接) between two spaceships, or in a landing approach by a vehicle onto an orbiting space station, a bump could rip open a ships skin, or a nudge could knock the station out of its orbit.The light-beam radar, which operates at a frequency of trillions of cycles(百万兆) per second, could easi
37、ly detect and measure the movement of a vehicle edging up to a satellite space station. A control system using so precise a signal as this would allow a huge vehicle to dock at a space station as lightly as a feather.（分数：4.00）(1).Laser-dopple radar _ .（分数：1.00）A.measures the movement of a spaceship
38、by means of light beamB.makes use of microwavesC.makes use of sound wavesD.both A and B(2).Laser-dopple radar is especially valuable in space missions because it _ .（分数：1.00）A.is one thousand times more precise than microwave radarB.provides precise measures of the velocity of space vehiclesC.is a n
39、ew system of radarD.can measure the movement of a spaceship less accurately than a microwave radar(3).Which of the following statements is NOT true according to the passage _ .（分数：1.00）A.accuracy in speed measurement is essential to spaceshipsB.the speeds of space vehicles will vary greatlyC.inaccur
40、acies in measurement could cause accidents in space missionsD.a bump could affect the preciseness of the laser-dopple radar(4).Implied but not stated _ .（分数：1.00）A.Laser-dopple radar is more accurate than microwave radarB.Microwave radar may not ensure absolute precision in measuring varying speedsC
41、.The light-beam radar can measure only slow speeds with accuracyD.Microwave radar operates at a higher frequency than laser-dopple radarBD/BFor sometime past it has been widely accepted that babiesand other creatureslearn to do things because certain acts lead to “rewards“; and there is no reason to
42、 doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological “drives“ as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, no
43、otherwise.It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.Papousek began his studies by using milk in normal way to“ reward“ the babies and so teach them to carry out some simple movements, such a
44、s turning the head to one side or the other. Then he noticed that a baby who had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the childrens responses in situations where no milk was provided. He quickly fou
45、nd that children as young as four months would learn to turn their heads to right or left if the movement “switched on“ a display of lightsand indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as thr
46、ee turns to one side.Papouseks light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would “smile and bubble“ when the display came on. Papousek concluded that it was not prim
47、arily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.（分数：4.00）(1).According to the author, babies learn
48、 to do things which _ .（分数：1.00）A.will satisfy their curiosityB.will meet their physical needsC.are directly related to pleasureD.will bring them a feeling of success(2).In Papouseks experiment babies make learned movements of the head in order to _ .（分数：1.00）A.be praisedB.please their parentsC.be rewarded with milkD.have the lights turned on(3).The babies Would “smile and bubble“ at the lights because _ .（分数：1.00）A.they succeeded in
