我觉得这道题是出在and的问题上,and连词前面是BM这个人做了实验,and之后是it指代主语说明了实验的重要性。这完全是两句不同的话,之间不应该用and应该用;连接。 可以属于run-on sentence 尤其是在前面还有个while做状语修饰整个句子的情况下,LZ可以连起来多读几遍相信就可以感觉到有不对劲的地方。 另外从简洁性的角度上来说, D使用的是一个同位语加定语从句修饰就把问题说清楚了而C重新写了一个句子来说明这句话,所以D更简洁扼要。 还有一个非常好的法规就是代词指代一般只要是使用有错,就会用抽象词来指代,我给你一道例题。 24. Even astronomers were amazed at the success of the Neptune flyby, which produced a photograph of a previously undetected moon; this is likely to result in increased governmental support for the hitherto neglected U.S. space program. (A) this is likely to result in (B) that will cause (C) and which is likely to result in (D) this success is likely to result in (E) it is likely to result with 这道题也是选D,this success是抽象词吧,this和that是指代。 -- by 会员 阿尔法柔笼 (2010/7/9 20:57:52)
我觉得and 没错吧? A do sth and B do sth,完全没错吧··
提醒一下~D中this在这里并非代词哦~ 另外,B肯定错。that一般不要用来指某个事。。GMAT不喜欢。。但可以用来比较。。例如A is bigger than that of B |
