CCTV showed the astronauts’ return Sunday after their Shenzhou Ⅶ ship’s re­entry vehicle burst through the Earth’s atmosphere to make a landing under clear skies in the grasslands of China’s northern Inner Mongolia region.The vessel floated down gently while attached to a giant red­and­white striped parachute,marking the end of the 68­hour endeavor.Premier Wen Jiabao applauded at mission control in Beijing and shook hands with staff.“This mission’s success is a milestone;a stride(一大步,发展)forward,” Wen said.“I would like to extend my congratulations to the heroic astronauts wh o successfully pleted this mission.”The spacewalk was a key step in mastering techniques for docking two orbiters to create China’s first orbiting space station.Tied to handles attached to the Shenzhou Ⅶ ship’s orbital module,Zhai remained outside for about 13 minutes before climbing back inside.1.Which of the following is NOT true?A.Shenzhou Ⅶ returned to the earth on Sunday.B.Zhai Zhigang performed the spacewalk on Saturday. C.Three Chinese astronauts arrived in Beijing on Monday. D.Zhai said China wants to launch a manned mission by 2020. 2.What’s the meaning of the underlined word in Para.2?

智才艺州攀枝花市创界学校第九2021届高一语文第四次周练试卷12月23日启用一、现代文阅读〔本大题一一共2小题,一共21.0分〕〔一〕阅读下文,答复1-3题。

一个无所畏惧的社会是可怕的佳桐无所畏惧,经常被用来描绘英雄。

一个顶天立地的勇者,似乎也需有这样的风范。

孔夫子说过:“君子有三畏:畏天命,畏大人,畏圣人之言。

〞德国哲学家康德面对头顶的星空与心中的道德准那么,称自己“愈考虑愈觉神奇,内心也愈充满敬畏〞。

两位先哲并非先天害怕,更非后天无知,而恰恰是超越常人的智慧,让他们多了一份敬畏之心。

所谓敬畏,与一般的畏惧不同,它带着几分特别的敬重。

最典型的是HY徒,对神灵顶礼膜拜,丝毫不敢亵渎。

随着现代科学的开展,过去人们眼中的许多神秘现象,都得到了理性的解答。

但现代化可去除迷信,却不应去除敬畏;一个人可以不信神,却不能无视神圣的力量。

我们首先应敬畏自然。

相比宇宙和自然的无限,人的理性与才能是那么有限,我们对世界的“未知〞要远远大于“〞。

敬畏自然,就是成认我们自身的渺小,正视大自然的神圣。

我们还应敬畏生命。

生命都是神圣的,每个人之于他们的家庭、友人和团队,都是难以割舍的存在。

敬畏生命,就是将人的生命摆在首位,而且珍视人的自由选择,维护人的开展时机。

对生命的敬畏还应包括和我们一样有心跳、有亲情、有痛感与悲戚的其他生灵。

我们同样需要敬畏法律、敬畏规那么。

法律、规那么作为人们一共同遵循的行为标准,一经确立,就具有不被逾越、不被变通、不被潜规那么左右的神圣性。

世间需要敬畏的东西还有很多。

比方,敬畏历史、敬畏先贤、敬畏百姓、敬畏科学、敬畏正义。

对其心存敬畏,不是受HY怒目、铁棒皮鞭的恫吓,更多是发自内心的尊重。

从本质上讲,敬畏与HY息息相关,没有敬畏之心,就没有HY之真。

当今社会,敬畏已染上浓重的功利色彩,需不需敬畏,也要先问一声“有没有用〞,对自己有用,就烧香拜佛;假设不再管用,那么立马丢开。

因此,最被敬畏的往往是势力与金钱,但这两样东西最易变幻。

And they must have 36 how difficult it is to write a good 37 book. Either the author has aimed too 38 , so that the chil dren can’t follow what is in his (or more often, her) story, 39the story seems to be talking to the readers. The 40 children’s books are neither very difficult nor very simple, and satisfy both the child who 41 the story and the 42 who reads it. Unfortunately, there are in fact 43 books like this, so the problem of 44 the right bedtime story is not 45 to solve. This may be 46 many of the books regarded as works of children’s literature were 47 written for grown-ups. “Alice in Wonderland” is perhaps the 48 example of this. Children, left for themselves, often 49 the worst possible interest in literature. Just leave a child in a(n) 50 or library and he will 51 likely choose books written in an unimaginative wa y, or have a look at children’s comics, full of the stories and 52 which teachers and right-thinking parents consider of no value. Perhaps we parents should 53 trying to brainwash children into 54 our taste in literature.

Friendly C. different D. similarATwo years after the First World War (1914-1918), a small group of soldiers left the army and returned to their home town in France. Most of them lived well, but one of them was poor. His name was Clinton.Once a year they had supper in Barton’s house. Barton was very rich.One evening just in the year when they returned to their home town, Barton showed his friends a large gold coin at the supper table. The coin was passed around and praised by everyone. At the same time they talked. They soon forgot about the coin.After supper, Barton asked for his coin, but nobody knew where it was. It was lost.One man said that everyone must be searched. One by one they turned their pockets inside out. Only Clinton refused.“I didn’t steal the coin, and I will not be searched,”he said.After that, people turned their heads away from Clinton when they met him. He grew poorer. Soon his wife died.A few years later, Barton had his house repaired. The lost coin was found under the floor. Barton felt sorry and went to Clinton to apologize.“But,” he asked, “you knew the coin was not in your pocket. Why did you refuse to be searched?”“Because I was a thief,” Clinton answered. “My pocket was full of food at that time. I had taken some food from the table to carry to my hungry wife and children.”56. When did the story take place?A. In 1920.B. After 1945.C. In 1914.D. In 1918.57. We can infer that the coin was passed around and praised mainly because ________.A. it showed that Clinton was very richB. they had not other topics to talk about at the tableC. it was a large gold coin and few people owned oneD. the people were happy and friendly to each other58. Everyone was to be searched because ________.A. they stole some food from the tableB. the gold coin was lostC. Clinton had stolen the gold coinD. someone had stolen the gold coin59. Clinton refused to be searched because ________.A. there was some food in his pocketB. he didn’t steal the coinC. he was poorD. the gold coin was in his pocketBEducation is not an end, but a means to an end. In other words, we don’t educate children only for the purpose of educating them. Our purpose is to fit them for life. In some modern countries, it has for some time been fashionable to think that by free education for all — whether rich or poor, clever or stupid, one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough. We find in some countries a far larger number of people withis thought to be dirty and shameful in such countries. But we have only to think for a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor. We can live without education, but we would die if we had no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible disease in our towns ...In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in a particular way. Firstly, each of us can do whatever work is suited to his brains and ability. Secondly, we can realize that all jobs are necessary to society and that it is very bad to be ashamed of one’s work. Only such a type of education can be considered valuable to society.60. The writer of the passage believes that _______.A. education can settle most of the world’s problemsB. free education for all probably leads to a perfect worldC. free education won’t help to solve social problemsD. all social problems can’t be solved by education61. The writer wants to prove that _______.A. our society needs all kinds of jobsB. our society needs free education for allC. a farmer is more important than a professorD. people with university degrees refuse to do what they think is “low” work62. According to the passage, we can learn that _______.A. work done with hands is dirty and shamefulB. wor k done with hands is “low” workC. work done with hands is the most importantD. we shouldn’t regard work done with hands as “low” work63. The purpose of education is _______.A. to choose a system of educationB. to prepare children mainly for their future lifeC. for everyone to receive an education fit for himD. to build a perfect worldCDo you love the holidays, but hate gaining weight? You are not alone. Holidays are times for feasting and celebrating. Many people are worried about their weight. With proper planning, though, it is possible to keep normal weight during the holidays. Whether it is celebrating at the office party or sitting down for the traditional family dinner, you should regard eating as a chance for tasting a variety of foods.

If the passage appeared in a newspaper, which section is the most suitable one?A. Holidays and Festivals section.B. Health and Fitness section.C. Fashion section.D. Student Times Club section.DWhen I asked my daughter which item she would keep: the telephone, the car, the cooker, the computer, the TV, or her boyf riend, she said “the telephone”. Personally, I could do without the telephone entirely, which makes me unusual, because the telephone is changing our lives more than any other piece of technology.Point1The telephone creates the need to communicate, in the same way that more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been at school with all day. If the phone did not exist, would she have anything to talk about?Point2The mobile phone means that we are never alone. “The mobile phone saved my life,”says Crystal Johnston. She had an accident in her V olvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance (救护车) to her rescue.Point3The mobile phone removes our secret. It allows the marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask wherePoint4The telephone separates us. Antonella Bramante in Rome says, “We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near —but we didn’t meet for the first two weeks!”Point5The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers at the same time on chat lines. (At least my daughter does. I wouldn’t know what to talk about.) We can talk across the world. We can even talk to astronauts (if you know any) while they’re space-walking. And, with the phone line hooked up to the computer, we can access (进入) the Internet, the biggest library on earth.68.

Mobile phones are changing people’s life faster and faster.70. What is the best title of the passage?A. Power of the telephone.B. Kinds of telephones.C. How to use the telephone.D. Advantages of the telephone.信息匹配题:Children have gentle minds. To find the best way to teach children to share and care is easy.
