Ⅰ.阅读理解
Oumuamua,an object falling through space that was discovered on October 19th,has already made history.The speed at which it is moving relative to the sun means that
it cannot be native to the solar system.Its official name is thus Ⅱ/2017 UI,with the
“I” standing for interstellar(星际)—the first time this name has ever been used. 英语24字整体教学法
- 2 - That is exciting.Some scientists,though,entertain an even more exciting
possibility what if Oumuamua is not an asteroid(小行星),as most think,but an alien(外星的)spacecraft?Asteroids come in all 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 spaceship,since it
would minimize the scouring(冲刷)effort 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(发射机)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 asteroids,so probably has a similar composition.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(遗弃星球).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 come to the solar system from the vast space between the stars.
【语篇解读】 本文是一篇科普类的文章。Oumuamua的形状让一些科学家认为它可能是外星飞船,按这篇文章来说它最有可能是A space rock,但是Oumuamua的真实身份还有待发现。
1.What makes some scientists think Oumuamua is possibly an alien spacecraft?
A.Its size. B.Its color.
C.Its shape. D.Its speed.
C [推理判断题。根据第二段中“Such a shape would be a sensible choice for
spaceship,since it would minimize the scouring(冲刷)effort of interstellar dust.”可知,是它的形状让一些科学家认为 Oumuamua可能是外星飞船。]
2.What does the underlined word “that” in the third paragraph probably mean? 英语24字整体教学法
- 3 - 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.
D [代词指代题。根据第二段中“Such a shape would be a sensible choice for
spaceship,since it would minimize the scouring(冲刷)effort of interstellar dust.”和第三段最后“At that range,the telescope should be sensitive enough to pick up a
transmitter(发射机)about as powerful as a mobile phone after just a few
seconds—worth of observations.”此处that的意思是指 Oumuamua是艘宇宙飞船的可能性。]
3.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.
B [细节理解题。根据最后一段中“By far the most likely option is that it is
exactly what it seems to be:a huge space rock”可知,按这篇文章 Oumuamua最有可能是A space rock。]
4.It can be inferred from the last paragraph that .
A.Oumuamua will return to where it's from soon
B.Oumuamua's real identity remains to be found out
C.astronomers have not seen signs of Oumuamua's artificial origin
