六、阅读理解
The idea of life in outer space has been talked about for a long time. Some scientists say that life development on Earth was far too unlikely for it to have happened anywhere else. Things had to be perfect for us to make it on this planet.
Other scientists say that space is too big. Stars and other planets are far too numerous for there to be no other life in the universe.
For many years, there have been reports of visitors from other planets. People all around the world have claimed to see alien spaceships or even aliens themselves.
There have been glimpses of these so-called UFOs (unidentified flying objects) flying through the air and they have even ben captured on video. Some Americans believe that the U.S. Army found an alien spaceship crashed in the desert and then lied to the press about it. Although these sightings may be true, scientists have not found significant evidence that aliens exist.
If you go out into the countryside on a clear night and look up, you can see thousands of stars. Those stars make up a tiny part of our universe. There are more stars, planets, and galaxies than we can count. Even the smartest scientists can’t even come close to defining how big space is. The number of possible stars and planets out there is bigger than our ability to count. If we are really on the only planet that can sustain life, then we are very special in a universe full of amazing things.

Suddenly, a UFO appeared and it made our spacecraft land on another planet. On the planet, a very strange-looking alien met us. He took my friends and me to see its master. All the aliens had four eyes, two heads and six legs. They had a white body and no hair.
The planet looked like a prison (监狱). We were scared and they gave us some food. No one ate the food.
The next day, they gave us a long list of things to do, but we couldn’t understand them at all. They put us in a small room. After that, they did experiments(试验) on us. A few of us died and they put the rest of us back into the room.
One day, the alien who brought us to our room forgot to lock the door, so we ran away. Soon we flew back to the earth in our spacecraft.
We told people about our experience but no one believed us! After that, I never go into space again.

1．C
【详解】句意：——比尔的妈妈是做什么的？——她在一家医院当医生。她被认为是医院里最好的医生。
考查介词辨析。for为了；as作为；at在。根据“She works…a doctor in a hospital”可知此处应用动词短语work as表示“任……职，当……”；根据“is considered”可知此处应用动词短语be considered as表示“被认为/看作是”。故选C。
2．C
【详解】句意：——你今晚要去罗斯的派对吗？——我应该要去的，但是我得待在家里，因为我感冒了。
考查情态动词辨析。could可以；had to不得不（过去式）；might可能；should应该；have to不得不。根据“but I …stay at home because I catch a cold”可知，应该要去参加派对，但是因为感冒了，所以不得不待在家，故选C。
3．D
【详解】句意：——放学后打篮球怎么样？——听起来很好。
考查非谓语及情景交际。How about doing sth. “做某事怎么样”，表提建议，故第一空应为playing。Never mind没关系；Sounds great听起来很好。上文表提建议，则“听起来不错”适合作为答语。故选D。
4．C
【详解】句意：——那边那个女孩是你妹妹，不是吗？——不是。她是我的一个同学。
考查反意疑问句和名词复数。根据“The girl over there is your sister, ... ”可知，该句是反意疑问句，遵循“前肯后否，前否后肯”原则，因此第一空的附加疑问句要用否定形式，排除AB选项；再根据“She is one of my ...”可知，“one of+名词复数”表示“……之一”，因此第二空要用名词复数classmates，排除D选项。故选C。
5．C
【详解】句意：哦，你是个了不起的厨师！你做的蛋糕味道很好，所以卖得很好。这样，我们可以在一个月内得到足够的钱去旅行。
考查词汇辨析。well好，副词；good好的，形容词。根据“The cakes you cooked taste..., so they sell...”可知，第一空作感官动词taste的表语，应使用形容词；第二空修饰动词sell，应使用副词。故选C。
6．A
【详解】句意：——你为什么不接我的电话？——对不起，我那时正在洗澡。
考查动词辨析及动词时态。answer回答；receive收到。“接听电话”应用answer。根据“at that time”可知，打电话时正在洗澡，故为过去进行时。故选A。
7．B
【详解】句意：——我到办公室后做的第一件事就是打开电脑。——那是因为你必须在电脑上工作。我们的办公室里甚至没有电脑。
考查定语从句及词义辨析。分析句子可知，空格处连接词引导定语从句，修饰先行词the first thing，先行词有序数词修饰，故用that引导定语从句。some一些，用于肯定句中；any任何，用于否定句或疑问句中。结合“don’t”可知，此处是否定句，应用any。故选B。
8．B
【详解】句意：——你对我们的英语老师说了什么？——我问她我是否通过了考试。
考查特殊疑问句和宾语从句。how怎样；if如果；what什么；whether是否。根据“I asked her ... or not I had passed the exam.”可知，第一空是问对老师说了什么，应用what；再根据“or not”可知，第二空应用whether；whether or not“是否”。故选B。
9．B
【详解】句意：——你能帮我说服他不要在北京找工作吗？——如果他下定决心，没有人能使他改变主意。
考查代词辨析。his他的，物主代词；him他，宾格。动词persuade后接宾格him。anybody任何人；nobody没有人。根据“can make him change his idea if he has made up his mind”可知，决定了就没有人能改变他的想法，故选B。
10．A
【详解】句意：医生给我量了体温后，说我发高烧了，必须卧床休息一天。
考查冠词用法。have a high fever“发高烧”；stay in bed“卧床休息”。故选A。
11．yourselves
【详解】句意：蒂姆和杰克，你们昨天在公园玩得开心吗？enjoy oneself“玩得开心”，根据“Tim and Jack”可知，这是两个人，所以反身代词用yourselves表示“你们自己”，故填yourselves。
12．Indian
【详解】句意：Verma对印度历史感兴趣。India“印度”，名词，此处应用形容词Indian“印度的”，作定语修饰名词history。故填Indian。
13．friendly
【详解】句意：在课堂上，老师们对我们很严厉，但是下课后他们非常的友好。friend“朋友”，名词，由空前be动词可知，此处用形容词做表语，“friend”的形容词为“friendly”。故填friendly。
14．location
【详解】句意：你能告诉我博物馆的位置吗？locate“位于”，动词。此处是of所有格，指博物馆的位置，故用名词location“位置”。故填location。
