1、课时作业(十七)Module 5Section Introduction &Reading and VocabularyComprehending阅读理解ABlack holes? White galaxy? Blue planets? Space is not black，but light green, a team of astronomers announced on January 10. They studied the light sent out by 200,000 galaxies. What they found was that the average colour o

2、f the universe is a bit greener than turquoise (绿宝石)The discovery was part of an attempt to test theories about how stars and galaxies form. Most astronomers believe that the universe probably started with a“blue period” when young blue stars filled space. Now the universe is in a “green period”. Th

3、ey believe it will finally enter a “red period” when the older, redder stars appear.“The reason for the colour changing is that the rate of stars forming is changing，” said Ivan Baldry, an astronomer who worked to find the average colour of light in the universe.Research presented by NASA scientists

4、 shows that the highest point of starforming may have occurred earlier than previously (以前) believed. It was probably very soon after the “Big Bang (宇宙大爆炸)” that many scientists believe it gave birth to the universe.There is no way any human could actually see the green colour.“The only way to see i

5、t is if you saw all the universe from the same distance away and it was not moving，” Baldry said. Baldry and his coworker, Karl Glazebrook, have both joked about possible marketing (营销) opportunities for the new colour.Perhaps colouroftheuniverse Tshirts or coffee cups could become popular. But Bald

6、ry allowed，“I dont know if you can patent (专利) a colour, thats not our business. We havent actually been to a paint shop yet to see if they have a name for this.”1The astronomers discovered the colour of the universe _.Awhen they were researching on the age of the universeBwhen they attempted to tes

8、 green at presentCthe universe has changed its colour several timesDthe universe will finally turn red3We can infer that the most popular colour of Tshirts would be _.Ared BblueCgreen Dlight green4Which of the following is NOT mentioned in the passage?ANo human can see the real colour of the univers

9、e.BThe theory of “Big Bang” is widely received by scientists.CThe rate of stars forming is causing the change of the universes colour.DHumans can receive light from at least 200,000 galaxies.BA home science experiment recently took the world by storm. Two teens from Toronto, in Canada, sent a Lego m

10、an rising above the Earth and captured their tiny astronauts trip on film.Mathew Ho and Asad Muhammad, both 17, used a weather balloon to launch their plastic lego model 16 miles above the Earth. This is inside a part of Earths atmosphere.The two teens were inspired by a similar project performed by

11、 students at the Massachusetts Institute of Technology (MIT). The MIT students had launched a weather balloon with a camera into near space and taken many unusual images of the Earth. Mathew and Asad then spent four months figuring out how to launch their own spacecraft into the space.Traveling to s

12、pace is expensive for NASA, but Mathew and Asad worked hard to keep their costs down. They bought much of their equipment used and even sewed the Lego mans parachute (降落伞) by hand. In total, the project cost only $400.“We had a lot of anxiety on launch day because there were high winds when we were

13、going up，” Mathew told reporters. They had to pump extra helium (氦) into the balloon so that it would rise quickly and avoid being blown too far off course by the strong winds.The toy astronauts journey lasted 97 minutes before the balloon broke and he fell back to Earth. Mathew and Asad then spent

14、two weekends looking for their spacecraft. It had landed 76 miles away from the launch site.The student scientists are currently finishing up their final year of high school and applying for colleges. They are also looking into more doityourself space projects.“I guess the sky is not really the limi

15、t anymore，” Mathew told reporters. “We never knew wed get this far. Its been a lesson for us that hard work pays off.”5By saying “took the world by storm” in the first paragraph, the writer meant the experiment_.Adestroyed the world Bflooded the worldCfascinated the world Dmanaged the world6Which of

16、 the following about the students at the Massachusetts Institute of Technology (MIT) is RIGHT?AThey were examples for Mathew Ho and Asad Muhammad.BThey helped Mathew Ho and Asad Muhammad to achieve dream.CThey launched weather balloon together with Mathew Ho and Asad Muhammad.DThey studied with Math

17、ew Ho and Asad Muhammad in the same school.7How did Mathew and Asad keep their costs down?ABy sewing the weather balloon themselves.BBy borrowing spacecraft from the MIT students.CBy making their spacecraft by hand.DBy using secondhand equipment.8What problems did Mathew and Asad have on launch day?

18、AThey ran out of helium.BThe wind was too strong.CThe balloon suddenly broke.DTheir spacecraft was blown away.课时作业(十七)阅读理解A【语篇解读】本文是一篇科技文，介绍科技的最新发现宇宙的颜色。1答案与解析：B第二段第一句“The discovery was part of an attempt to test theories about how stars and galaxies form.”说明了这一发现是在理论检测过程当中做出的。2答案与解析：D第二段最后一句“They b

19、elieve it will finally enter ared period when the older，redder stars appear.”为该选项提供了依据。从第二段可看出宇宙的颜色由蓝到绿，最终将变而还未变红，所以C项中的已经变了几次不符合事实。而B项“all the heavenly bodies”远远大于文中stars这一范围。A项中的all the time表示的频率过高。3答案与解析：D综合第一段第三句“What they found was that the averagecolour of the universe is a bit greener than tu

20、rquoise(绿宝石)”和最后一段第一句“Perhaps colouroftheuniverse Tshirts or coffee cups could become popular.”可看出答案。4答案与解析：AD项来自于第一段倒数第二句；C项来自第三段第一句；B项来自第四段最后一句。A项与第六段有很大的差异。B【语篇解读】本文主要介绍了两个青少年利用气象气球把他们的玩具乐高人送到太空的过程和结果。5答案与解析：C词义猜测题。根据第一段的第二句话可知两个青少年把一个玩具乐高人送入了太空，并把过程拍了下来，因此作者想要表达的是这个试验吸引了世人的目光。6答案与解析：A细节理解题。根据文章第三段的第一句话可知选A。7答案与解析：D细节理解题。结合文章第四段的第二句话可知他们使用二手的设备来节省费用。8答案与解析：B细节理解题。根据文章第五段中的“We had a lot of anxiety on launch day because there were high winds when we were going up”可知，在他们进行发射的那天遇到的问题是风比较大。
