Ⅴ.(2021潍坊)完形填空
Spacesuits don’t just make astronauts look cool. Without these 16 suits, astronauts wouldn’t be able to leave their spaceship. That is to say, they wouldn’t be able to 17 on the moon or work outside the International Space Station.
Space is a 18 place for human beings. Firstly, there is no air to breathe. Secondly, space also has high levels of radiation(辐射), energy that can pass through our 19 and make us sick(生病的). Thirdly, some parts of space are really cold 20 other parts are very hot. So astronauts could die in a few seconds if they 21 outside their spaceship without their suits. With a spacesuit, though, astronauts can move around in space for several hours.
Spacesuits keep astronauts 22 sealed(密封的) inside. A backpack sends O2 in to let astronauts breathe(呼吸) normally. At the same time, the CO2 that astronauts breathe out is sucked away(抽走). The suit also protects 23 from harmful radiation and fast-moving space dust. 24 the spacesuit is another suit that looks like a pair of tight pajamas(睡衣) with little pipes running through them. Water runs through these pipes to 25 astronauts because wearing a spacesuit can make astronauts very hot!

Ⅵ.任务型阅读
The sun gives us light and heat. We can’t live without the sun. The sun is at the centre of the solar system. Its gravity(引力) holds all the planets in the right place and makes them travel around it.
The sun is the biggest object in the solar system. Do you know how big it is Well, use your head and imagine. Its diameter(直径) is about 109 times as big as the earth’s. You could fill with over a million earths inside the sun.
Scientists think that the sun(and the planets) formed(形成) the solar system about 4.59 billion years ago, so it is pretty old.
The sun gives us too much heat. It is a planet with high temperature. Its temperature is 5,500 degrees Celsius on the surface and 15.6 million degrees Celsius at the centre. The temperature of the sun isn’t the same all over. In some places where “sun spots” happen, it isn’t as hot as elsewhere.
It is made up of almost all of hydrogen(氢气), with a little helium(氦气) and a few heavier elements including oxygen. And there’s even some iron there too.
Light from the sun reaches the earth in just 8 minutes!
Remember not to look directly at the sun. It could seriously damage your eyes.
根据短文内容,完成下列各题。
26.In the solar system, the sun’s makes all the planets travel around it.
27.请把画线句子翻译成汉语。
28.What’s the temperature at the centre of the sun
29.Why can’t you look directly at the sun

Ⅳ.12.B 代词辨析。“四个孩子在一把小伞下走着。他们没有一个人淋湿。你能猜到原因吗 ”“因为没有下雨!”all意为“(三者或三者以上)都”;none意为“一个也没有”;most意为“大部分”;some意为“一些”。由句意可知选B。
13.D 时间状语“ten minutes ago”提示谓语动词用一般过去时。
14.B
15.C 代词的用法和动词的时态。由后半句“so we know nothing about it(所以我们对这个消息一无所知)”可知,前半句我们当中没有人听说过这个消息。强调对现在的影响,应用现在完成时。no one意为“没有人”,常单独使用。none意为“没有人”,其后常和of短语连用。
Ⅴ.16.B 形容词。由下句“astronauts wouldn’t be able to leave their spaceship”可知,没有宇航服,宇航员将不能离开宇宙飞船。由此推知,宇航服是特别的。special 意为“特别的”。
17.C

19.A 名词。由上文“space also has high levels of radiation”可知,太空存在很强的辐射,由此推断这种辐射会让身体生病。body 意为“身体”。
20.D 连词。第三,太空的一些地方很冷,然而其他地方却很热。while意为“然而”。

22.A 副词。宇航服把宇航员安全地密封在里面。safely 意为“安全地”。
23.C
24.B 介词。宇航服下面一层是像紧身睡衣一样的衣服。under 意为“在……下面”。
25.C 动词短语。由下文“because wearing a spacesuit can make astronauts very hot”可知,穿宇航服会让宇航员很热,故推知水流经这些管子能让宇航员变凉快。cool off 意为“变凉”。
