(29661-!-item-!-188;#058&003962) Unlike frogs that metamorphose from tadpoles into adults within a one-year period, it takes three to four years for the mountain yellow-legged frog of the Sierra Nevada to reach adulthood, and so they are restricted to deeper bodies of water that do not dry up in summer or freeze solid in winter.

我觉得如果我做这个题。首先排除A和B,因为和D、E比,那个it明显很诡异的,我感觉说不出什么理论,就是一种做题的感觉。
关于C选项。我觉得要看逗号。in the Sierra Nevada作为同位语,应当修饰前面的部分。但这样一来,逻辑不通。
再看D和E。区别就在最后,一个是thus,一个是and。再看划线部分后面的restricted to,是个动词吧,D选项使它没主语,如果没有一个连词连接,是说不通的。and是连词,thus是副词,副词不能连接两个动词,不然就是run-on句型了。-- by 会员 bennywang2usa (2010/7/15 22:37:15)
多謝![](/static/legacy-emoticon/18.gif) 我後來想想 一般 thus 當連接詞他會加SV 例 I have all the tools I need, thus I will be able to fix the car without having to call a mechanic 所以, thus+Ving 的結構是不對的 是不是這樣理解啊? 你覺得呢? |
