A Chinese spacecraft called Chang’e-4 made the first soft landing on the far side of the moon at 10:26 a. m. on January 3, 2019. It is the first time that a spacecraft has made it. The far side is the part of the moon that always faces away from the Earth.
After it landed on the ground, the spacecraft took the first photo of the “dark side” of the moon, and sent it back to the Earth through the Queqiao relay satellite（中继卫星）. The scientists launched the satellite into space in May, 20l8.
“What we know about the far side of the moon is from orbiters（轨道飞行器）, from Russia, the US, European countries, China and India,” Andrew Coates, a professor of Physics at University College London, told a reporter.
China sent Chang’e-4 into space from the Xichang Satellite Launch Center in December, 2018. Sending a spacecraft to the far side of the moon isn’t easy, because the far side is covered in craters（环形山）. Some of its mountains are higher than Qomolangma, the highest mountain on the Earth.
What’s more, we can’t see the far side because it takes the moon about 28 days to move around the Earth with the same side always facing our planet. Direct communication with the Earth is impossible on the far side of the moon, so communications must go through a communication satellite. That was why scientists launched the Quegiao relay satellite.
31．What does the underlined word “launched” mean in Chinese
A．研发 B．改造 C．发射 D．追踪
32．Why did scientists launch the Queqiao relay satellite
A．To help Chang’e-4 move around the moon.
B．To get information of other relay satellites.
C．To send pictures of space to scientists on the Earth.
D．To provide a way of communication with the Earth.
33．What do the last two paragraphs mainly tell us
A．Why sending a spacecraft to the far side of the moon is difficult.
B．How China sent Chang’e-4 into space from the Xichang Satellite Launch Center.
C．The differences between the mountains on the Earth and the mountains on the moon.
D．How the moon travels around the Earth with the same side always facing our planet.
34．What CANNOT we know from the passage
A．When Chang’e-4 landed on the far side of the moon.
B．How scientists sent the satellite into space.
C．What Chang’e-4 did after landing on the far side of the moon.
D．What people knew about the far side of the moon.
35．Where does the passage probably come from
A．A notice. B．A newspaper. C．A letter. D．A diary.
C

The West Lake is one of the most beautiful lakes in China. It’s in Hangzhou.

Leifeng Pagoda(雷峰塔)
Leifeng Pagoda lies on Sunset Hill along the south route of the West Lake. It’s a five-storey(层)tower with eight sides. The pagoda is a symbol of the West Lake scenic spots.
38 The pagoda collapsed(倒塌)in 1924. In October 1999, the government decided to rebuild it and in 2002, it was open to the public.
39 In the story, a snake girl and a young man fell in love with each other, but an old monk separated them. She had to stay under Leifeng Pagoda for years.

The giant panda is one of the most popular animals in the world. A giant panda can grow up to 1.5 meters tall and weigh up to 160kg. People think the giant panda is very lovely. ①So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people about animals that are in danger and raises money to save them.
The giant panda only lives in the wild in China. In the early 1980s, there were only 1,000 left in the wild. The main reason why pandas are endangered is that the area where panda can live has become smaller.
The WWF works to help giant pandas in the wild in many ways. One of the ways is to increase the size of panda reserves（自然保护区）. Some reserves need to be joined together by planting bamboo between them to make “corridors”. These are paths that lead from one reserve to another. No one may harm the pandas in these areas. The corridors let pandas move from one habitat（栖息地）to another to look for food. ②People are working very hard to make sure the giant panda does not die out.
56．How long and heavy can a giant panda grow to be
57．将文中画线的句子①改为被动句。

1．句子意思：我们没有足够的时间完成这项工作，更何况去看电影了。
考查比较级。much more更加，何况；many less无此结构；a lot more多得多；a lot less少得多。根据“We don’t have enough time to finish the work, …to go to the cinema”可知，连完成这项工作的时间都不够，更何况去看电影了，因此选A。

3．句子意思：——周先生，我们组所有的学生中，谁住得最远？——我想是李雷。

4．句子意思：——你最好不要到处乱扔垃圾！——我很抱歉。我会把它捡起来。
考查动词短语。pick up捡起；get off下车；wake up醒来；put out扑灭。根据“You’d better not drop litter everywhere!”可知，此处指的是“捡起垃圾”，因此选A。
5．句子意思：——你能看到树上有多少只鸟？ ——我能看到几百只鸟。

longer更长的，比较级；shorter更短的，比较级；long长的；short短的。根据后文“It showed life expectancy(平均寿命) had been cut down by 5.5 years there.”可知，人的平均寿命减少了5.5岁，所以空处应该是说较之以前的寿命更短了，通过句子意思可知是隐性比较级，所以用比较级shorter。因此选B。
12．句子意思：研究人员认为，中国严重的空气污染应承担责任。
where哪儿，宾语从句中用来引导以where开头的特殊疑问句；if是否，宾语从句中用来引导一般疑问句；that宾语从句中用来引导陈述句，在从句中无意义也不作成份；when用来引导以when开头的特殊疑问句。根据空前的think可知，后面做动词think的宾语从句；根据空后的“the heavy air pollution in China should be to blame”可知，本句是陈述句，所以应该用that做宾语从句的引导词。因此选C。
13．句子意思：这真的是实情。
truly真的，真诚地，副词；fact现实，事实；truth真相，实情；the truth真相，实情，truth 前加 the 的习惯用语。根据空前“the heavy air pollution in China should be to blame”可知，中国严重的空气污染应承担责任，也就是说研究人员发现了实情，应该用truth；truth 前习惯加 the，表示特指，the truth实情，真相。因此选D。
14．句子意思：然而，效果似乎并不太好。
Though虽然，尽管；However然而；Instead反而；Unless除非，如果不。根据空前“Our government has already done something.中国政府已经做了一些事情”及空后句“it doesn’t seem to work so well效果似乎并不太好”可知，前后存在转折关系；however位于句首时，要用逗号与句子其它部分隔开，though放句首时，后面一般直接加句子；根据空后的逗号及句子意思可知，空处应该用however。因此选B。

that那，用于比较句型中，可用来代替“the+不可数名词”；this这个；it它；those那些。根据句子意思及空前的“was worse than”可知，本句是比较句型；在比较结构中，前面出现的名词如果后面同样出现，可以用that（代替前面的“the+不可数名词”）；those（代替前面的复数名词），根据句首的the air pollution是不可数名词，可知后面用that替代，that in other places在这儿意为“其它地方的污染”。因此选A。
19．句子意思：这是由煤加热引起的温度升高和废气引起的。
rise上升，动词原形；rising动名词形式；to rise动词不定式形式；raise增加，提高。根据空前的by，可知介词by后要用动名词形式，结合选项可知空处用rising。因此选B。

driving开车，动名词形式；to drive开车，动词不定式形式；drove动词过去式形式；drive动词原形。根据空前的instead of，其用法是instead of sth/doing sth，结合选项可知，空处应该用动名词形式driving。因此选A。

big大的，形容词；serious严重的，形容词；strong强壮的，形容词；heavily严重的，副词形式。根据句子意思可知，本句是含有定语从句的复合句；根据“that pollute ___12___should be closed”可知，pollute是定语从句的谓语动词，副词修饰动词，所以空处应该用副词形式heavily。因此选D。
23．句子意思：我们需要改善我们的环境，尽管它可能很贵。
improves提高，改善，动词三单形式；improving动名词形式以及现在分词形式；to improve动词不定式形式；improve动词原形。根据句子意思可知，need是句子的谓语动词，根据其用法need to do sth需要做某事可知，空处填动词不定式形式to improve。因此选C。
24．句子意思：保护我们的环境意味着保护我们自己。
us我们，人称代词宾格形式；our我们的，形容词性物主代词；ourselves我们自己，反身代词；ours我们的，名词性物主代词。根据空前的“We need___13___our environment”及主语we可知，空处是表达“保护我们自己”，所以应该用反身代词ourselves。因此选C。
25．句子意思：另一位研究人员李红斌说。
another三者以上的另一个；other其他的，后面接名词；the other两者中的另一个；others其他的，相当于other加名词形式。根据句子意思及空后的researcher可知，空处是表达“另一位研究人员”；句中没有说是两者，所以应该用三者以上的另一个another。因此选A。

34．细节理解题。根据“A Chinese spacecraft called Chang’e-4 made the first soft landing on the far side of the moon at 10:26 a. m. on January 3, 2019.”；“After it landed on the ground...relay satellite.”以及“Sending a spacecraft to the far side of the moon isn’t easy, because the far side is covered in craters（环形山）. Some of its mountains are higher than Qomolangma, the highest mountain on the Earth.”可知，能够知道嫦娥四号到达月球远端的时间、到达之后做了什么以及从地球的远端，人们可以了解到什么，而文章没有提到科学家们是如何将中继卫星发送到太空的。因此选B。
35．推理判断题。通读全文可知，文章主要讲了为了探索月球，中国发射的嫦娥四号月球探测器首次在月球背面着陆，并拍摄了月球“黑暗面”的第一张照片，因此文章可能来源自报纸。因此选B。

43．根据句子意思，该题需填“死于……”，且“地震”为外因，需用“die from”，且该句时态为一般过去时，因此填died；from。
44．数词+times+比较级+than...“比……几倍……”；four times“四倍”；four times more than...“比……多四倍”。因此填①times②more③than。

48．句子意思：我一点儿也不喜欢它们。此处作like的宾语，指的是前句提到的lions“狮子”，为复数，指“它们”，应使用they的宾格形式them。因此填them。
49．句子意思：熊猫是所有动物中最害羞的。该空前面是定冠词the，在be动词are的后面，应为形容词的最高级。根据“You should be quiet when you see them.”可知，熊猫比较害羞， shy“害羞的”，最高级为shyest/shiest。因此填shyest/shiest。
50．句子意思：它们来自四川省。 Sichuan Province“四川省”，是地点； be from“来自”。因此填from。

52．句子意思：我认为最友好的动物是海豚。该空修饰名词animals，前面是定冠词the，因此为形容词的最高级。根据“ If people are in water and can’t swim, they may come up to help.”可知，海豚对人类友好。friendly“友好的”，最高级为friendliest/most friendly。因此填friendliest/most friendly。
53．句子意思：海豚能表演得很好。can是情态动词，表示“能够”，后接动词原形。根据“They can do many things to make people laugh”可知，海豚应该是表演得好。 act “表演”，为动词。因此填act。
54．句子意思：它们能做许多事情来让人们笑。make sb do sth“让某人做某事”，所以此处应为动词原形，又根据“Dolphins can act well.”可知，海豚会表演来让人笑，laugh“笑”。因此填laugh。
55．句子意思：我认为它们可能是世界上最高的动物。该空修饰名词animals，前面是定冠词the，因此为形容词的最高级，句子主语they指的是giraffes“长颈鹿”，可知长颈鹿是最高的，tall“高的”，最高级为tallest。因此填tallest。
56．根据“A giant panda can grow up to 1.5 meters tall and weigh up to 160kg.”可知，大熊猫的身高可达1.5米，体重可达160公斤。因此填It can grow up to 1.5 meters long and weigh up to 160kg.
57．根据“So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol.”可知该句中that引导的主语从句为一般过去时的主动句，改为被动句时，时态保持不变，原句中的宾语the giant panda作主语，原句中的谓语chose改为被动语态，其结构为：was / were+过去分词，主语the giant panda为单数名词，be动词应用was，动词chose的过去分词为chosen，即谓语部分为was chosen，剩余部分保持原来的位置。因此填the giant panda was chosen as its symbol。
58．根据“The main reason why pandas are endangered is that the area where panda can live has become smaller.”可知，大熊猫濒临灭绝的主要原因是大熊猫能够生存的区域变小了。因此填Because the area where panda can live has become smaller.

60．分析句子可知，该句为现在进行时的陈述句；People翻译为“人们”；are working very hard翻译为“努力工作着”；to make sure翻译为“为了确保”；the giant panda翻译为“大熊猫”；does not die out翻译为“不灭绝”。因此填“人们为了确保大熊猫不灭绝而努力工作着。”
One possible version:
Let’s try our best to protect the environment
Dear friends,
I’m a student of Grade 9 in Dazhou. As we know, we have only one Earth. But in recent years, many disasters happened on the Earth and unusual weather appeared very often. All these bad things were caused by the terrible environment, but the terrible environment was caused by humans. As students in Dazhou, what should we do
First, we should spread something unusual to protect our environment. For example, we can give talks on how important the environment is. Second, we should save water and electricity in our daily life. Third, in order to reduce air pollution, it’s better to go to school by bus or bike or on foot. Fourth, we can sort the garbage into four categories: recyclable, harmful, dry and wet waste. And we can reuse bags instead of plastic bags.
If we all keep doing these things, I believe the environment will be better and better. Let’s try our best!
