课时作业(十四)

Ⅰ. A

【文章大意】本文是一篇说明文,主要介绍了新年超级月亮。

1.C 推理判断题。根据第一段第三句“The second comes on the last night of the month,

ending up with a lunar eclipse (月食).”和第三段第一句“For those who may miss the

night of Jan. 1, an even more charming supermoon will rise on the night of Jan. 31.”

可推知,此处的that是指1月31号的超级月亮,故选C。

2.A 细节理解题。根据第三段第二句“That will be the second full moon of the month, which is usually called a ‘blue moon’ because a double full-moon month occurs essentially once in a blue moon—about every 2.5 years.”可知,1月31号的超级月亮是蓝月亮,故选A。

3.A 细节理解题。根据最后一段最后两句“So prepare your self for the super blue blood moon on the night of the lunar eclipse. To get the full effect of the lunar eclipse, watch at moonset.”可知,作者建议在1月31号月亮落下时观看月食,故选A。

4.A 标题概括题。根据第一段第一句“Human beings are in for a double treat in January with the appearance of two supermoons.”开篇点题,并结合对全文的整体理解可推知,本文主要讲的是两个新年超级月亮,故选A。

B

【文章大意】本文是一篇说明文,主要讲述了科学家发现了Proxima b星球,Proxima b星球与地球的情况非常相似。

5.A 细节理解题。根据第二段最后一句“…the sky on its world is orange without any blue at all…”可知,Proxima b星球有着橙色的天空,故选A。

6.C 推理判断题。根据第四段最后两句“Gold records w ere sent up into space on Voyager probes in 197

7. If aliens (外星人) on Proxima b had played the records, they would have found human voices and pictures that showed the rich diversity of Earth.”可推断出gold records里有录制好的声音,故选C。

7.D 推理判断题。根据最后一段最后一句“‘Proxima b lo oks to us like a promising Planet B, just in case things go really south on this blue planet,’ the Chicago Tribune wrote.”这句话的意思是Proxima b是一个有潜力的星球,万一地球上的情况变糟糕呢,故选D。

8.A 观点态度题。最后一段最后一句“‘Proxima b looks to us like a promising Planet B, just in case things g o really south on this blue planet,’ the Chicago Tribune wrote.”可知Chicago Tribune认为Proxima b是一个有潜力的星球,以防地球上的情况变糟糕,所以Chicago Tribune对于发现这个星球非常激动,故选A。

Ⅱ.【文章大意】本文是一篇说明文,主要介绍了中国的太空实验室“天宫2号”的情况。

1.in 考查介词。酒泉卫星发射中心地处戈壁滩,表示在某地,故用介词in。

2.was 考查动词时态。与上文was fired呼应可知,事情发生在过去,故用一般过去时,即was。

3.whose 考查定语从句。whose引导非限制性定语从句,在从句中作定语,修饰先行词Tiangong-2。

4.was placed 考查动词时态和语态。与语境last month呼应可知,事情发生在过去,且place和句子主语the lab构成逻辑上的被动关系,故用一般过去时的被动语态。

5.scientific考查词性转换。scientific是形容词,在句子中作定语,修饰名词experiments。

6.other 考查固定搭配。in other words意为“换句话说”,符合语境,故用other。

7.technologies 考查名词复数。与语境the techniques 呼应可知,此处用名词复数形式作宾语。

https://www.wendangku.net/doc/37830002.html,eful 考查词性转换。根据语境可知,此处是形容词作表语,故填useful。

https://www.wendangku.net/doc/37830002.html,pleted 考查非谓语动词。have sth done意为“使某事完成”,符合语境,故用过去分词作宾语补足语。

10.successfully 考查词性转换。副词修饰动词、副词、形容词或者整个句子,在句子中作状语,故用副词successfully修饰动词landed。

Ⅲ.There is too many people and too many pollution on Earth. If we moved to the moon one day, how ┬what

would life be like there?

In my opinion, life would be much more comfort on the moon than on Earth. There would

高考英语易错题专题训练-阅读理解练习题及答案解析

一、高中英语阅读理解 1.阅读理解 Since we've headed into the snowy part of the year, it seems like a good time to solve a language puzzle that Eskimos have a huge number of words for snow. The idea was popularized by the now well-known expert Benjamin Lee Whorf in the 1940s. His number was approximately five Eskimo words for snow, but somehow the story was so wide spread and romantic that it got out of control and grew bigger and bigger. There are two problems with the concept of Eskimos having tons of words for snow. First, Eskimos speak at least two different languages—Inuit and Yupik. Just as we have talked about how English and many other languages developed from a common language called Proto-Indo-European, Inuit and Yupik come from a different common language called Eskimo-Aleut. So saying Eskimos have 100 words for snow is like saying Europeans have 100 words for kings or queens. It might be telling you something broad about culture, but it isn't really telling you much about language. The second problem is "What is a word?” The Inuit and Yupik languages make words in different ways from how we make words in English. For example, the West Greenlandic word 'siku,' (sea ice), is used as the root for 'sikursuit (pack ice), 'Sikuliaq (new ice), and 'sikurluk (melting ice). But it's not that West Greenlandic has so many more words for describing snow than English, it's just that West Greenlandic expresses ideas by combining meaningful units of language together into one word while English uses more phrases and compounds. We express all the same ideas; we just do it a little differently because of the way our language is built. So you're probably still wondering, "If it's not 50 or 100 or 400 words, how many is it?" Well, Woodbury lists 15 that are present in a Yupik dictionary published in 1984, but he says that depending on how you look at it this is not an exact number. It could be 12; it could be 24. But it's certainly not 100. Sometimes, the "hundred words for snow" puzzle is used to argue that because Eskimos have so many words for snow, they think about snow in ways that we can't even begin to imagine—that your language decides or limits your thoughts. Languages are just different. They don't decide what we are able to think about or are not able to think about. I can think about snow floating on water even if we don't have a word for that in English. So when you're out skiing or snowboarding or just shoveling your driveway this winter, don't believe the people who try to tell you that Eskimos have 100 words for snow. (1)Why are Eskimos thought to have so many words for snow? A. Because snow is everywhere where Eskimos live. B. Because the story about it got enriched and believed. C. Because snow is of great importance to Eskimos. D. Because Eskimos have great affection for snow. (2)How does the writer explain the first problem? A. By presenting figures. B. By making comparisons. C. By quoting sayings. D. By adopting idioms.

高考英语重点知识点大全

高考英语重点知识点大全 主语从句 主语从句是在复合句中充当主语的从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。 1. It 作形式主语和it引导强调句的比较。 It 作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。被强调部分指人是也可用who/whom。 例如: It is a pity that you didn’t go to see the film. It doesn’t interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window. 2. 用it 作形式主语的结构。 (1) It is +名词+从句 It is a fact that …事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) it is +形容词+从句

It is natural that…很自然… It is strange that…奇怪的是… (3) it is +不及物动词+从句 It seems that…似乎… It happened that…碰巧… (4) it +过去分词+从句 It is reported that…据报道… It has been proved that…已证实… 3. 主语从句不可位于句首的五种情况。 (1) if 引导的主语从句不可居于复合句句首。 (2) It is said ,(reported) …结构中的主语从句不可提前。 例如: It is said that President Jingo will visit our school next week. (right) That President Jiang will visit our school next week is said. (wrong) (3) It happens…,It occurs…结构中的主语从句不可提前。 例如: It occurred to him that he failed in the examination. (right) That he failed in the examination occurred to him. (wrong) (4) It doesn’t matter how/whether …结构中的主语从句不可提前。
