看了好多的精华帖子, 551.Once positioned in space, the Hubble Space Telescope will capture light from sources twenty times faintercompared to those that can be detectedby ground-based instruments. (A) compared to those that can be detected (B) compared to those they can detect (C) than that can be detected (D) than those that can be detected (E) than those detecting the key 比较考点:比较对象。sources——those that can be detected 都是答案d 还没更正
既然比较的是光,那么 than 后面跟着的就是 light,应该是 that 而不是 those。正确的句子应该是:Once positioned in space, the Hubble Space Telescope will capture light from sources twenty times fainter than that that can be detected by ground-based instruments. 注意,是连用两个 that 的。不是我打错了 以上是牛人的论述,只是在这里插一下
Once positioned in space, the telescope will capture light from stars and other sources 20 times fainter than can be detected by ground-based instruments.
