【文章內(nèi)容簡介】 (星際)”—the first time this name has ever been used.That is exciting. Some scientists, though, entertain an ever more exciting possibility: what if Oumuamua is not an asteroid(小行星),as most think, but an alien(外星的)spacecraft? Asteroid e in ll sorts of shapes and sizes, but Oumuamua seems particularly different. As best as astronomers can tell, it is cigarlike, being roughly 180 meters long but only about 30 meters wide. That makes it longer than anything known of in the solar system. Such a shape would be a sensible choice for a spaceship, since it would minimize the scouring(沖刷)effect of interstellar dust.With that in mind the Breakthrough Listen project, an organization aimed at hunting for alien life, plans to turn the world’s biggest radio telescope, the Green Bank instrument in Virginia, towards Oumuamua to see if it can hear anything interesting. Oumuamua is currently about twice as far from Earth as Earth is from the sun. At that range, the telescope should be sensitive enough to pick up a transmitter about as powerful as a mobile phone after just a few seconds—worth of observations.Will it find anything? Almost certainly not. Oumuamua has the same reddish color as many as asteroids, so probably has a similar position. And, if it really is a spaceship, it is strange that signs of its artificial origin have not been seen already. It could, in theory, be a derelict(遺棄星球). But in that case the telescope is unlikely to hear anything. By far the most likely option is that it is exactly what it seems to be: a huge space rock, one that has e to the solar system from the vast space between the stars.32. What makes some scientists think Oumuamua is possibly an alien spacecraft?A. Its size. B. Its color. C. Its shape. D. Its speed.33. What does the underlined word “that” in the third paragraph probably mean?A. The research into the solar system.B. The purpose of hunting for alien life.C. The effect of interstellar dust on Oumuamua.D. The possibility of Oumuamua being a spaceship.34. What is Oumuamua most likely to be according to the author?A. An asteroid. B. A space rock. C. Interstellar dust. D. An alien spacecraft.35. It can be inferred from the last paragraph that__________.A. Oumuamua will return to where it’s from soonB. Oumuamua’s real identity remains to be found outC. astronomers have not seen signs of Oumuamua’s artificial originD. the Green Bank telescope has already heard something from Oumuamua第二節(jié) (共5小題;每小題2分,滿分10分)根據(jù)短文內(nèi)容,從短文后的選項中選出能填人空白處的最佳選項。選項中有兩項為多余選項。Many students want to learn English well, but don’t know where to start. Here is some advice.Before you begin(or go back to) studying English, ask yourself: Why do you want to study English? 36 Like every decision in life, studying English must be something you want to do.If you know why you want to study, setting goals is easy. For example, maybe you want to travel to an Englishspeaking country. Great! Your goal might be to learn “Survival English”. 37 Then, you may also ask yourself how long you need to study to achieve your goals. This answer is different for every student. 38 If you work 60 hours per week, don’t plan on spending another 40 hours a week studying English. Start off slow, but study regularly. Use material that is challenging, but not too difficult. 39 Do you study best at night, or on the bus on your way to work? Do you like to study alone in a quiet place, or with friends and background music? After you have studied for a few weeks, adjust your study plan accordingly.It’s generally accepted that 40 .If you aren’t having fun learning English, you are not studying the right way!You can be a serious student who has fun at the same time. Make up your own rewards programme to give yourself encouragement to stay on task.A. It is wise to make a timetable.B. The important thing is to be realistic.C. It’s better to find out what works for you.D. Learning English is interesting and rewarding.E. Whatever your goals are, work hard on them.F. The things we do best in life are the things we enjoy doing.G. Is it because you want to, or beca
