Of course, we may 2 with our guide-books the history and 3 developments of a town and get to know them. 4 then, if we take our time and 5 in a town for a while, we may get to know it better. When we 6 it as a whole, we begin to have some 7, which even the best guide-books do not answer. Why is the town just 8 this, this shape, this plan, this size? Why do its streets 9 in this particular way, and not in any 10 way?Here even the best guide-book 11 us. One cant find in it the information about how a town has developed to the 12 appearance. It may not describe the original (最初的) 13 of a town. However, one may get some idea of what it 14 look like by walking around the town. One can also imagine 15 the town was first planned and built. Then one can learn more about in what direction the town 16 to develop.What is the 17 of studying towns in this way? For me, it is 18 that one gets a greater depth of pleasure by visiting and seeing a town with ones own eyes. A 19 visit to a town may help one better understand why it is attractive 20 just reading it in a guide-book.(A)1. A. in B. atC. by D. on(B)2. A. write B. study C. tell D. remember(D)3.

It suggests people believe what they hear through the grapevine(小道消息) _1_ they have evidence to the contrary.Researchers, _2_ students by using a computer game, also found gossip played an important role when people _3_ decisions. “We show that gossip has a strong _4_, even when people have _5_ to the original information as well as gossip about the same information. Thus, it is _6_ that gossip has strong controlling potential,” said Ralf Summerfield, an evolutionary biologist at the Max Planck Institute in Germany, who led the study.In the study, the researchers _7_ the students money and allowed these to give to others in a series of rounds. The students wrote _8_ about how others played the game that everyone could review. Students tended to give _9_ money to people described as “scrooges(吝啬鬼)” and more to those described as “_10_ players”. “People only believed the gossip, not the past decisions,” Summerfield said in a telephone interview.The researchers then took the game a step _11_ and showed the students the actual decisions people had made. But they also supplied false gossip that contradicted that _12_. In these cases, the students _13_ their decisions to award money on the gossip, _14_ the hard evidence.“If you know what the people did, you should care, but they still _15_ what others said,” Summerfield said. Researchers have _16_ used similar games to study how people cooperate and the _17_ of gossip in groups. Scientists define gossip _18_ social information spread about a person who is not _19_. In evolutionary term, gossip can be an important tool for people to _20_ information about others reputations or find the way through social networks at work and in their everyday lives. (D)1.

Now they hope it wont be too long before they are able to _1_ its existence. Their confidence is the _2_ of a new discovery of the mystery animal in Hubei Province.Ten Chinese _3_, enjoying a holiday in a National Forest Park, were driving down a road. As their bus turned a corner, the men were suddenly _4_ by what they saw. Three _5_ animals, covered with long black hair, were crossing the road. On seeing the _6_, the engineers immediately stopped and ran after them. _7_, when they saw how the animals moved through the forest with great _8_ strength, they did not dare to follow any further.The men did not take any _9_. However, scientists are _10_ by the discovery, because the engineers were all very educated people and scientists feel they can _11_ what they described.After the discovery, scientists returned to the forest and _12_ some hair and measured footprints. About 20 inches appears to be the animals foot! Chinese scientists have now set up a special group to exchange information and make a _13_ of the forest. But in the meantime, some people _14_ to believe that this half-man, half-monkey exists. They will not believe that it is _15_ until one of the animals have been caught.(A)1.

It is with the help of telescopes 1 we can study the solar system and view the conjunctions of stars. Not just that, the various planets, galaxies, satellites and asteroids that we get to see only in the books and magazines are made more familiar to us 2 the telescopes. They act as barrier- breaking instruments between the human beings and the 3 space. The universe is no more a (an) 4 to us that exists beyond our 5 and we owe it all to the telescopes.The modern day telescopes 6 them a wide array(阵列) of accessories（附件）and it is with the 7 of these accessories that it becomes much more easier to successfully put the telescopes into proper use. Let us see what are the important accessories that go well and are a must-have for most telescope into proper 8 There are two main 9 of telescopes, the refractor (Galileo) telescopes（折射望远镜）and the reflector (Newton) telescopes. The refractor telescope uses an objective lens 10 bends the light 11 the eyepiece（目镜）. While the reflector telescope uses a 12 , which collects the 13 and then directs it towards the 14 .Though both the refractors as well as the reflector telescopes are easily 15 in the market we should take the following points into 16 before buying a telescope.Do not get 17 by the magnification of the telescopes. This is 18 magnification alone is of 19 use if it just produces large but hazy images.If we are careful about remembering the 20 points then it wont take us long to choose a tel
