Among them, calligraphy,poetry(诗)and painting were the most famous. Often they would be put together in art. These became important starting with the Song Dynasty.Calligraphy is the art of handwriting. In the old time, the Chinese considered writing as an important form of art. Calligraphers would practice for years to learn to write perfectly, but with style. Each of over 40, 000 Chinese characters(汉字)needed to be written correctly.A nd each stroke(笔画) in a character had to be written in a certain order.Poetry was also an important form of art. Great poets were famous all over the country, but all educated people were expected to write poetry. During the Tang Dynasty, poetry was so important that writing poetry was part of the examinations to become a civil servant (文官) and work for the government.Chinese painting was often connected with calligraphy. It is one of the oldest artistic traditions in the world. The most traditional way of Chinese painting is known as "national" or "native" painting, which is quite different from Western painting. People can draw mountains, homes, birds, trees and water on it.28.Calligraphers needed to write over characters correctly in the old time.A . 10,000 В. 20, 000 C . 30,000 D . 40,00029.

The strokes of each character could be written in any order.C . Poetry was an important form of art.D . Chinese painting was often connected with calligraphy.DI came to the United States from Africa to live with my uncle Jim in Maryland. One year later, I lost my sight because of a serious illness.Jim told me not to go out. He worried I would get lost or hit by a car. But I was dogged. I told him I'd pay attention. I believed I'd succeed. I must succeed. I must put my will into action. I dreamed of being a broadcaster.Then a neighbor told me that a public library in Washington D.C. was offering a free course, specially designed for blind people. This was an important chance for me.But how would I map my way? I knew that the American singer Ray Charles, also blind, got around on his own without a cane(手杖). His secret was to count steps. But I couldn't see what to do that way. Instead, I developed my imagination, sensing the layout (布局) of places I visited and taking notes of landmarks in my mind.At first, I would have to stop to imagine and map a new space in my mind. The next time I visited that place, I used that to find the way. Today, I am used to doing it. But I've still lost my way many times. I have to swallow my pride to ask for help, not thinking about what others think or say about me.Sometimes I'd be down and I'd consider giving up. Perhaps my uncle was right. Maybe I'd stay home and wait until someone came to help. On those days, when I lost my way, I'd go to bed with a bad feeling. ____▲___ I had a strong wish to beat blindness and be successful, and that was usually enough to get me out of bed the next day and try again.Along the way, I learned to be patient with myself and realized that asking for help didn't diminish(贬低)me in any way. I've got three academic degrees so far.Today, I'm a reporter and broadcaster. I've achieved my dream.Yes, I've lost my way many times - and found it again. Yes, I've come close to being hit by a car but never been hit by one. When people ask, "Aren't you afraid to be out alone?" The answer to me is clear: I would face danger and find happiness instead of staying home and being unhappy.32. The writer ______ one year after he moved to the US.A . got lostB . became blindC . lost his parentsD . was hit by a car33. Which of the following can be put in "____▲___ " in Paragraph 6?A . And my uncle knew it wellB . But I kept that to myselfC . And my uncle was with meD . So I gave up trying again34. What might Jim say when he talks about the writer at the end of the story?A . That boy can see!B . That boy is so poor!C . We are free now!D . I've done much for him!35.The best title of this passage might be _______.A . An Imagination to SucceedB . Life with My UncleC . A Common Way to SuccessD . Study in the LibraryEDifferent gestures(手势)mean different things in different countries. Sometimes a gesture that is polite in one country is not polite in another and should not be used. Different meanings of gestures can also cause problems in understanding what another person is trying to say. A gesture that many people do not understand is one that uses the thumb. Most westerners will sometimes show that they like something by holding out a closed hand with the thumb lifting in the air. This is called giving someone or something "the thumbs up". Often, only one thumb is used, so it should be"the thumb up".The usual explanation (解释) for the origin of this gesture is not really correct. It says that in ancient Roman times, when people were pleased with the way a gladiator(角斗士)hadfought, they showed their thumbs up. When they were not pleased, they gave the thumbs down. When a gladiator was given the thumbs up, the emperor allowed him to live. When a gladiator was given the thumbs down, the emperor ordered him to be killed.The truth is, however, it was translated into a wrong meaning by mistake. If people wanted to save the gladiator, they put out their hands and hid their thumbs in their hands. If they wanted the gladiator to die, they pointed their thumbs straight at him.36. Westerners lift their thumbs when they _______.A . cannot understand youB . like somethingC . want to be politeD . dislike something37. Most people think that in ancient Rome, "thumbs up" meant that _______.A . the emperor could dieB . the people wanted the gladiator to liveC . the fighting could continueD . the people were not pleased38. In fact, if people wanted a gladiator to live, they ________.A . hid their thumbsB . pointed their thumbs downC . lifted their thumbs upD . pointed their thumbs at him39. The main idea of this article is about ________.A . gestures around the worldB . closed thumbsC . gestures in ancient RomeD . the thumbs-up gesture四、口语应用(每小题1分,共5分)阅读下面对话,从7个选项中选择5个恰当的句子完成此对话。

6.难度系数:0.7第Ⅰ卷一、选择题:本题共25小题,每小题2分,共50分。

在每小题给出的四个选项中,只有一项符合题目要求。

1.读下图,与②地相比,⑤地的地球自转速度()A.角速度和线速度都大B.角速度小,线速度相等C.角速度和线速度都小D.角速度相等,线速度小【答案】D【详解】根据所学知识可知,地球自转线速度由赤道向两极点递减,⑤地在30°S,②地在赤道上,因此⑤地比②地线速度小,AB错误;除南北极点外地球各地的自转角速度相同,⑤地和②地都未在极点,因此两地角速度相同,C错误,D正确。

故选D。

某国产科幻大片中的“太空电梯”给观众带来了强烈的视觉震撼,人类通过在外太空地球静止轨道上建设一个大型空间站,把空间站和地面用一根缆绳连接起来,宇航员通过竖直的箱体电梯直通空间站。

下图为“太空电梯”和空间站示意图。

据此完成下面小题。

2.在大型空间站上观察日出、日落时()A.晨线每小时15°向东倒退B.日出观察时间晚于对应球面C.昏线每小时15°向西倒退D.日落观察时间与对应球面一致3.与地球相比较,“太空电梯”()A.空间站线速度比地球小B.运行中箱体角速度不变C.运行中箱体线速度不变D.空间站角速度比地球大【答案】2.C3.B【解析】2.大型空间站上的海拔远高于对应地面,能更早看到日出,更晚的看到日落,BD错误;由于地球每小时自西向东自转15°,因此晨昏线不停地由东向西每小时移动15°,反映出晨线和昏线都是以每小时15°向西倒退,C正确,A错误。
