The mountains surrounding Los Angeles effectively shield the city from the hot, dry winds of the Mojave Desert, （also preventing） the circulation of air.

  • A、and also prevent
  • B、and also preventing
  • C、they also prevent
  • D、but they also prevent

题目解答

答案

D

解析

此题考察的是句子的连贯性和逻辑关系。句子的前半部分提到山脉保护洛杉矶免受莫哈韦沙漠的热风和干燥风的影响，后半部分需要一个连词来连接，同时表达出防止空气循环的意思。选项D中的“but they also prevent”不仅连接了前后两部分，还表达了防止空气循环的意思，符合题意。
