选项A中and前后不需要时态平行么? -- by 会员 yippewanner (2013/2/23 16:10:36)
我觉得时态主要是由meaning决定的,平行在形式上主要是要求结构一致,至于时态要根据meaning决定,用time marker判断。比如这题中各自有明显的time marker: ten to twenty billion years ago(表示过去时)和ever since(现在完成时)。-- by 会员 Lynsey玲 (2013/2/23 18:22:48)

这题是考察平行吧 首先,noun that is句型是典型的啰嗦结构=adj+noun ,因此排除ABC 再看DE,overestimate the amount of energy used by ...与 underestimate that used by....平行。其中,that指代"the amount"(是原amount的copy,所以不能用it) |
