Many people around the world believe that aliens exist. There are several reasons for this. First, the universe is huge. There are billions of stars and planets in space. Scientists think that some of these planets might have conditions similar to Earth’s. Since life exists on Earth, it is possible that life could exist on other planets too. Second, people have seen strange lights in the sky or heard unusual noises at night. Some of these experiences are because of natural phenomena, but others are still unexplained. For example, some people have seen objects that they believe are alien spaceships. They can’t explain what these objects are, so they think they must be from outer space. Third, some scientists have sent messages into space to contact aliens. They hope that one day aliens will receive these messages and reply. Because of these efforts, many people believe that we will find alien life in the future. However, not everyone believes in aliens. Some people refuse to believe in them because there is no real proof. They think that all the stories about aliens are just made up or misunderstandings of natural things. Whether aliens exist or not, the idea of exploring space and finding other life forms is very exciting. It makes us think about our place in the universe. 1. Why do some people think alien life might exist? A. Because the universe is too small to have only Earth. B. Because some planets might have conditions similar to Earth’s. C.

Because they can’t explain what the lights are. B. Because the lights are always moving very fast. C. Because they have seen aliens come out of the lights. D. Because the lights are always seen at night. 3. Why do some people refuse to believe in aliens? A. Because they think the universe is too big. B. Because there is no real proof of aliens. C. Because scientists have not sent any messages into space. D. Because they think aliens are dangerous. 4. Which of the following is TRUE according to the passage? A. All people believe that aliens exist. B. Scientists have already received replies from aliens. C. The idea of exploring space is not interesting at all. D. Some people believe in aliens because of unexplained experiences. 四、完形填空（共 10 小题，每小题 1 分，满分 10 分） 阅读下面短文，掌握其大意，从A、B、C、D四个选项中选出最佳选项。 One night, Tina saw a strange yellow light diving down to the ground.

They are very common in English. 1. ______ The most common words used to introduce these clauses are “because”, “as”, and “since”. They all mean “for the reason that”. We use “because” when we want to give a direct reason. 2. ______ For example, “I was late because I missed the bus.” Here, “because I missed the bus” explains why I was late. “As” and “since” are used when the reason is already known or not the most important part of the sentence. 3. ______ For example, “Since you are tired, you should go to bed early.” Here, “since you are tired” is a reason that the listener already knows. We can also use “because of” to give a reason. 4. ______ For example, “The game was cancelled because of the rain.” Here, “because of the rain” gives the reason using a noun phrase. A. They can come at the beginning or the end of the sentence. B. It is followed by a noun phrase, not a full clause. C. They tell us the cause of an action or situation. D.
