  Ⅴ.串点成篇微表达

  网购对越来越多的人充满了吸引力(appeal to)。根据大众评论(comment),网购是一种先进的(advanced)购物方式。一方面,它包含了(contain)各种各样的非常有价值(be of+n.)的商品。另一方面,许多人羞于(be ashamed of)与店主面对面地讨价还价(bargain),因为有时任何一方行为不当都会是彼此恼怒(annoy),但网购可以避免这种尴尬的局面。越来越多的人更喜欢网购,这很好的平衡(balance)了他们的时间,感受和工作。

  Ⅰ.阅读理解

  It's up there right now, flying about 340 miles above the earth. It's a telescope in the sky. It's called the Hubble Space Telescope. The telescope itself is not really much to look at. If you could see it right now, you might think it's just a big bucket with two solar arms. It's about the size of a school bus and weighs about as much as two elephants.

  But that silver bucket is pure gold for astronomers. It has made such a big impact that NASA, the space agency that takes amazing pictures, calls Hubble the most important advance in astronomy since Galileo's telescope. Hubble didn't win high marks in the beginning. It was launched on April 24,1990, aboard the space shuttle Discovery from Kennedy Space Center, Florida. The next day it was released into space, but scientists soon realized there was a big problem. The telescope's primary mirror had a flaw (瑕疵) . Hubble became a late­night talk show joke. But in December of 1993 shuttle Endeavour astronauts repaired the telescope. The late­night joke stopped.

  So why is Hubble so special? Because it's on what NASA calls the ultimate mountaintop. Sitting high above the earth, far away from our light­polluted cities and hovering (盘旋) far away from clouds and storms, Hubble has a good view of the universe.

  Scientists have used it to make observations about planets, stars, galaxies and to show parts of our universe we didn't know. The telescope has made more than 1 million observations and astronomers have used Hubble data in more than 12,700 scientific papers, making it one of the most productive scientific instruments ever built.

Eventually, Hubble will stop working. NASA hopes to use a space shuttle to bring it
