1. Idiom: (1) believe that+clause (2) believe to do/be
2. the underlined part acts as an absolute phrase to modify "explosion"
3. "that" functions as an object in the attributive clause and therefore can be omitted.
A: is a complete sentence rather than an absolute phrase B: "it" is redundant C: wordy D: believe that+clause E: correct作者: haochan 时间: 2011-5-30 16:34
个人觉得选B吧
首先我觉得从逻辑上来说应该是由于爆炸产生的超新星的类型是科学所未知的，而不应该是爆炸。
one就近指代前面的整个发现，即爆炸，所以需要用it指代超新星。
另外，to be有“会成为”的意思在里面 更准确作者: kikisunflower 时间: 2011-5-30 17:20
The issue comes from OG10th and E is the correct answer.作者: Roxas605 时间: 2012-3-29 10:26
My question is that A also can be correct by using “嵌入式关系从句”.作者: lijiazhou 时间: 2012-3-29 17:27
