人教版（2019）必修3《Unit 4 Space Exploration》2021年單元測試卷

第二部分　閱讀理解（共兩節(jié)，滿分30分）第一節(jié)（共4小題；每小題6分，滿分30分）閱讀下列短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。

• 1．The sky is a large place，and though it has been carefully examined for centuries，new features still turn up.Last March it was the rule of Uranus（天王星），and last week astronomers announced what may turn out to be a new planet，though a very small one，in the solar system.
      The object was first sighted last month by Charles Kowal，an astronomer at the Hale Observatories in Pasadena，Calif.Mr Kowal observed a faint trail of light on photographic plates，indicating that something was moving in relation to the background of stars.Other observers have confirmed the discovery.
     The "mini-planet"，identified for the time being as "Object-Kowal"，appears to be about 1.5 billion miles away，between the orbit of Saturn and Uranus，and its diameter（直徑）has been estimated at between 100 and 400 miles.Its orbit has not been determined yet，but if the orbit proves to be roughly circular，like that of the major planets，the new object would probably take 66 to 70 years to make a circuit of the sun.
     Some astronomers have speculated that Mr Kowal's discovery may be the first indication of an asteroid（小行星）belt beyond Saturn.
  
  （1）What may have been found in the solar system according to the first paragraph？

  
  A．A small new planet.
  B．A new solar system.
  C．A large new object.
  D．A large new planet.
  （2）What can we learn from the second paragraph？

  
  A．What the object is like.
  B．How the object was found.
  C．Where the astronomers live.
  D．Why the object was moving.
  （3）What magazine might this passage be taken from？

  
  A．Astronomy.
  B．Industry.
  C．Spaceflight.
  D．Agriculture.

• 2．A new study suggests that dark markings on the planet Mars represent sand-not water.The research in 2015 suggested that lines on some Martian hills were evidence of water.Yet American scientists now say these lines appear more like dry，flows of sand.If water is present，it is likely to be a small amount.Water in liquid form would be necessary for microbial（微生物的）life.
     NASA，the American space agency，said more research is needed.Michael Meyer is the lead scientist for NASA's Mars exploration programme.He noted that the latest study does not reject the presence of water.But he admitted， "It just may not be as exciting as the idea of rivers going down the sides of cliffs（懸崖）. "
     The new findings come from a team led by Colin Dundas of the United States Geological Survey.His team measured 151 of these lines in 10 areas.Most of the lines end with slopes between 28 degrees and 35 degrees.These measurements are similar to active sand dunes（沙丘）on both Mars and Earth.A small covering of dust that moves and sometimes becomes lighter might help explain the markings.They usually appear in the Martian summertime，and then disappear until the next year.If these lines are dry，this suggests that recent Mars has not had large volumes of liquid water.Dundas and his research team say that many questions remain.
     "I still think that Mars has a great potential for having had life early on in its history，" Meyer said. "As long as that's true，we also have a reasonable possibility of life still being on Mars.It just happens to be cryptic or well hidden. "
     NASA currently has no robotic vehicle-either on Mars or in development-with the ability to climb steep slopes.The lack of such equipment has engineers coming up with ideas like Martian helicopters or planes without pilots.
  
  （1）What do American scientists find on Mars now according to their study？

  
  A．A lot of little life.
  B．An amount of water.
  C．Some Martian hills.
  D．Dark markings are sand.
  （2）When do the markings come out？

  
  A．In Martian spring.
  B．In Martian summer.
  C．In Martian autumn.
  D．In Martian winter.
  （3）What's Meyer's opinion about having life on Mars？

  
  A．Doubtful.
  B．Trustful.
  C．Indifferent.
  D．Objective.
  （4）What does the underlined word "cryptic" in Paragraph 4 mean？

  
  A．Undiscovered.
  B．Strange.
  C．Magical.
  D．Icy.

• 3．The sun is going to expand into the orbit of Mercury according to scientific calculations，which will result in the entire Earth catching on fire.Who will save the world？
     This imaginative tale is at the heart of the latest Chinese sci-fi movie The Wandering Earth.Unlike many American space-themed films where the solution to a disaster Earth faces is always fleeing（逃離）the planet in spaceships，this time we're taking the Earth with us.The film，which has made it the country's most successful film of all time，has offered a different and more ambitious idea.
     The "ambition" didn't come from nowhere.For thousands of years，"homeland" has had a soft spot in the hearts and minds of Chinese people.One old idiom that shows a strong feeling that Chinese people have had for their homeland is "luoyeguigen"，which means returning to one's homeland in old age，like fallen leaves returning to the roots of their tree.
     "What is Chinese sci-fi？" Guo Fan，the film's director，said in an interview. "A vehicle that really expresses our cultural and spiritual core（核心）can be called Chinese sci-fi.Otherwise，we're just following others and telling the same Hollywood stories. "
     And the makers of The Wandering Earth may have chosen the best time to tell its Chinese sci-fi story.The film was released on Feb 5，the first day of Chinese New Year.It was a time when many people had just made the hard journey back to their hometowns.So to them，there is only one possible way to tell the story：Earth goes wherever humans go，because it's our home.
  
  （1）The main purpose of the opening paragraph is to

  .
  A．give a brief account of the film
  B．warn people of the coming threat
  C．explore ways to avoid the disaster
  D．introduce the topic of the passage
  （2）The underlined phrase "a different and more ambitious idea" refers to

  .
  A．fleeing the Earth in spaceships
  B．bringing in huge success
  C．filling the gap in Chinese sci-fi movies
  D．helping Earth make its escape
  （3）Which of the following is unlikely to account for the success of the film？

  
  A．The rich imagination of the story.
  B．Hollywood-style space stories.
  C．The special cultural background.
  D．The time chosen to release the film.
  （4）What is likely to be title for the passage？

  
  A．Chinese Sci-fi Catches Up
  B．The Most Successful Chinese Sci-fi
  C．Chinese Sci-fi Sets a New Path
  D．Chinese Sci-fi Challenges

      For many years，I had a recurring （重復出現(xiàn)的）dream.I was a little girl again，rushing about，trying to get ready for school.
      "Hurry，you'll be late for school，" my mother called to me.
      "I am hurrying，Mom!What did I do with my books？"
      Deep inside I knew where the dream came from.It was about some unfinished business in my life.As a kid，I loved everything about school.I loved books，teachers，tests and homework.Most of all I longed to someday march down the aisle（通道）to receive my diploma.That seemed more appealing even than getting married.
      But at 15，I had to drop out because my parents couldn't afford tuition（學費）.My hope of getting a diploma was dead，or so I thought.Pretty soon，I married and had three children，and I thought："There goes my diploma."
      Even so，I wanted my children to be educated.But Linda，our youngest child，had juvenile arthritis （幼年型關節(jié)炎）in her hands and knees，which made it impossible for her to function in a normal classroom.I felt really sorry for her and I didn't want her to live her life with regret.I didn't give up hope of her being back to school in some way.
      One day，I saw an ad in the newspaper for evening courses. "That's the answer，" I said to myself.Linda always feels better in the evening，so I'll just sign her up for night school.
      Linda was busy filling out enrollment（入學）forms when the secretary said："Mrs.Schantz，why don't you come back to school？"
      I laughed："There's no way!I'm 55！" But he persisted，and before I knew what I had done，I was enrolled for classes in English and crafts. "This is only an experiment，" I warned him，but he just smiled.So，I told myself to try for just a semester and to see if it would work.Anyway，my dream was still there in my heart.
