Mars is not, it seems, the dry old planet we once believed__16__. Astronauts who are__17__to go there in the next decade may find plenty__18__water to slake(消退)their thirst.And with water present the__19__of finding some sort of life on Mars are__20__brighter.
This is the view of forty geologists who have been analyzing__21__of pictures and other scientific__22__obtained by robot explorers in the sixties and seventies.
To begin with, scientists thought the Red planet was as__23__as the Moon__24__dust storms swirling over vast sandy__25__. But now the picture is very different__26__mountains and valleys carved by__27__glaciers and rivers rushing and rumbling deep underground.
In a report on the analysis of the Martian pictures Dr.Michael Car of the U．S.Geological Survey comments: “I am convinced__28__lots of water on Mars.” Any surface water will be in the__29__of ice.But it could save explorers from__30__to take so much__31__with them.
The report says__32__Mars probably had a warmer climate in ages__33__due to its axis (轴) having been more tilted (倾斜) towards the sun.
__34__signs of plant or animal life have been detected by instruments landed on Mars，__35__the landing vehicles have been sent there for a few years.
16．A.it is B．it
C．it to be D．was
答案：C 依据新的资料显示，火星好像并不像我们过去认为的那么干燥。it代替前面的专出名词Mars; to be 为不定式的省略式，其后面省略了dry。 不定式的省略式通常省略to后面的成分，但后面为to be结构时，就要保留be而省略其后面的成分。
17．A.expected B．hoped
C．required D．sent
答案：A expect somebody to do something表示“期盼某人做某事”。这里用其被动语态形式：be expected to do sth。表示“某人被期盼做某事”。

C．more D．in
答案：B 此句的“plenty of＝a lot of”为固定词组，意思是“大量；很多；充分”。

答案：D 这里用powerful形容冰河对山谷冲刷的威力巨大。
28．A.there's B．there're

C．equipment D．oxygen
答案：A 此句的意思是“水的存在使探险者们不用随身携带大量的水。”
32．A.what B．if

Ⅲ.阅读理解(共20小题；每小题2分，满分40分)
阅读下面的短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。
A
In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet(彗星). When the fragments(碎片)landed in the southern part of the grand planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
The year is 2094. It had been announced that a comet is heading towards the earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the earth. The news has caused panic.
On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the spend of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and million of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
Millions of people are already dead in the southern part of the earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosion. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
Could it really happen? It has already happened more than once in the history of the earth. The dinosaur were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?
36．Which of the following is NOT true according to the author's description of the disaster in 2094?
A．The whole world becomes extremely cold.
B．All the coastal cities in Africa are destroyed.
C．The whole mankind becomes extinct.
D．The visit of the comet results in wars.
答案：C 辨别正误题。据第三自然段的描述可知，A、B、D均符合本文所假想的事实，只有C不符。文中“No more than 10 million people have survived”一句意为“只有一千万人幸存下来”，而C项说全人类都灭亡了。明显与文章不符。题干要求找出不对的选项。
37．Why does the author mention dinosaurs at the end of the passage?
A．Because they could only live in the warm climate.
B．Because they once dominated the earth.
C．Because their extinction indicates future disasters.
D．Because dinosaurs and humans never live in the same age.
答案：C 推理推断题。第三段中，作者描述假想的人类灾难……最终一段提到生活在地球上的恐龙在65 million years ago突然消逝(即灭亡)，很多科学家信任地球曾受到过外空星体碎片的攻击，故而导致恐龙绝种。由此示意人类将来的灾难。
38．In writing the passage, the author intends to________.
A．give an accurate description of the possible disaster in the future
B．prove that humans will sooner or later be destroyed
C．tell the historical development of the earth
D．warn of a possible disaster in the future
答案：D 观点态度题。本题要求考生推想作者意图。作者通过一段幻想的灾难和一段地球历史上毁灭过的恐龙绝迹的事实以及科学家们分析恐龙绝迹的缘由，来警示人类将来可能发生的灾难。
39．It can be concluded that the passage is most probably part of a(n)________．
A．horror story
B．news report
C．research paper
D．article of popular science
答案：D 推理推断题。据全文大意，又据文章的性质，可判定D为最佳选项。A、B、C均不太妥当。
B
(2022·山西省大同高一下学期期中)
Satellites are an important part of our ordinary lives. For example, the information for weather forecasts is sent by satellite. Some satellites have cameras which take photographs of the Earth to show how clouds are moving. Satellites are also used to connect our international phone calls.
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to us through satellites. Airplane pilots also sometimes use a satellite to help them find their exact location.
We use satellites to send television pictures from one part of the world to another. They are usually 35, 880 kilometers above the equator. Sometimes we can see a satellite in the sky and it seems to stay in the same place. This is because it is moving around the world at 11,000 kilometers an hour—exactly the same speed that the earth rotates. A satellite must orbit the Earth with its antennae (天线) facing the earth. Sometimes, it moves away from its orbit. So there are little rockets on it which are used to put the satellite back in the right position. This usually happens about every five or six days.
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth. A satellite usually works for about 10－12 years. Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired. Often, very old or broken satellites are left in space to orbit the Earth for a very long time. This is very serious because some satellites use nuclear power and they can crash into each other.
40．Which of the following is NOT done by satellites according to the passage?
A．Sending information for weather forecast.
B．Taking photographs of the Earth.
C．Sending TV pictures.
D．Providing food for airplane pilots.
答案：D 从第一段可知，A、B项的内容都是卫星的功能，从第三段可知，卫星还可以发送电视画面，而D项内容文中并未提及。
41．What's the speed the earth rotates at?
A．35,880 kilometers per hour.
B．335,880 kilometers per hour.
C．11,000 kilometers per hour.
D．110,000 kilometers per hour.
答案：C 从第三段的This is because it is moving around the world at 11,000 kilometers an hour—exactly the same speed that the earth rotates.可知C项为正确答案。
42．What does the underlined word “This” in the 3rd paragraph refer to?
A．A satellite.
B．A little rocket.
C．A satellite seems to stay in the same place in the sky.
D．The satellite puts the rockets in the right position.
答案：C 上一句话的意思是：有时候我们看到天空中的卫星好像呆在同一个地方，这是由于……，故本题答案为C。
43．Which is true of satellites?
A．A satellite usually works for about 10－12 years.
B．Every time a satellite gets broken, it is brought back to the Earth to be repaired.
C．A broken satellite is never left in space.
D．They often crash into each other.
答案：A 从最终一段的第三句话可知A项正确。
C
Brian arrived at the San Francisco airport two hours before the flight to Paris. He was wearing three shirts, a jacket，two pairs of socks，a pair of shorts, and two pairs of jeans. He was carrying one small backpack，which was very full, but he didn't have any other luggage. Brian needed to meet a man named Tony before he checked in for his flight. He found Tony near the Air France counter. Tony gave him a roundtrip ticket and a small package.
“Give this package to Jean Paul at the airport in Paris. He will have a sign with your name on it. I think you can find him easily，” Tony said，“You don't have any luggage, right？”
“Only this backpack，” Brian answered，“You said I could bring one carryon bag.”
“That's right. One carryon bag is fine. Have a good trip.”
“Thanks.”
Is Brian a criminal? Not at all. He is an aircourier. And he paid only $ 110 for the roundtrip ticket to Paris. Aircouriers get cheap airline tickets because they take important packages and papers to foreign countries. Businesses sometimes need to get packages and papers to people in foreign countries by the next day. Often，the only way they can do this is to use an aircourier company. It is not cheap for a business to send a package with an aircourier，but it is quick.
Every year about 80,000 people worldwide travel as aircouriers. The number of tickets for courier travel is growing by about 10 percent a year. However, aircourier travel isn't for everyone. But if you have very little money，can be flexible about your travel plans，and don't mind wearing the same clothes for a week，it can be a great way to take a vacation!
文章大意：文章主要叙述了利用航空快递的利与弊。
44．Why was Brian wearing so many clothes for his travel?
A．Because they were the uniforms for aircouriers.
B．Because that made him easier to be recognized.
