A working laboratory model of a new system of radar that makes use of a beam of light is said to be ten
32、 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 varying from spaceship orbital injection(进入)velocities(速度)of five miles per second down to v
33、irtual 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 rendezvous(对接) between two spaceships, or in a landing approach by a vehicle onto an orbit
34、ing 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 easily detect and measure the movement of a vehicle edging up to a satellite space station. A c

39、at a higher frequency than laser-dopple radarDFor 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 doubt that this is true. But it used also to be widely believed that effective rewards, at le
40、ast 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 otherwise.It is now clear that this is not so. Babies will learn to behave in ways that produc
41、e 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 as turning the head to one side or the other. Then he noticed that a baby who had enough to dri
42、nk 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 found that children as young as four months would learn to turn their heads to right or left if t
43、he 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 three turns to one side.Papouseks light display was placed directly in front of the babies and he
44、 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 primarily the sight of the lights which pleased them, it was the success they were achieving in so

46、C.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 lig

48、 of _ .（分数：1.00）A.the satisfaction of certain physiological needsB.their strong desire to solve complex problemsC.a basic human desire to understand and control the worldD.a fundamental human urge to display their learned skillsEThe difference between a liquid and a gas is obvious under the conditio
49、ns of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and fill it to the level of a free surface. A gas forms no free surface but tends to diffuse(扩散)throughout the space available; it must therefore be kept in a closed container or held by a gravitational field, as in the case of a planets atmosphere. The distinction was a prominent feature of e
