单选题 (The more straighter) the sun's rays shine down (upon) the earth, (the more heat) they give to the part of the earth (they touch).
  • A. The more straighter
  • B. upon
  • C. the more heat
  • D. they touch


【正确答案】 A
【答案解析】考查"the more...the more"的用法，意为“太阳光对地球的照射越直接，它照射到的地方放出的热量就越多”。这里，straighter本身已变为比较级了，more应删掉。
