1. That he is still alive is sheer luck.
2. Whether the plan is feasible remains to be proved.
有以下两个问题:
1. 麻烦为上面两个句子划分句子成分,主句和从句都划。
2. 第2句最后为何要用to be proved而不是to proved?是由于to后面不可以直接接形容词?
1. That he is still alive is sheer luck.
【翻译】他还活着全靠运势。
2. Whether the plan is feasible remains to be proved.
【翻译】这一计划是不是可行还有待证实。
句1,That he is still alive 是主语从句。
句2,Whether the plan is feasible 是主语从句。
成分划分如下:
1.That he is still alive(主语)is(系动词)sheer (形容词作定语)luck(表语).
2. Whether the plan is feasible(主语)remains(系动词)to be proved(表语).
(说明:remain to do ,最好把它当作固定搭配看待,不要具体细分,看作一个整体谓语即可。)
这两句的主语从句,略有差别:句1是个陈述事实的句子;句2是个含有一般疑问的句子。
可换为形式主语It引导:
1. It is sheer luck that he is still alive.
2. It remains to be proved whether the plan is feasible.
remains to be proved:有待于(被)证实。to be proved 是不定式的被动式,proved不是形容词。
