Once positioned in space, the Hubble Space Telescope will capture light from sources twenty times fainter compared to those that can be detected by gound-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
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。作者: anchoretes 时间: 2010-8-19 06:45
