he left his homeland_____never___come back again.
A determined,to come,
B being determined,to come
我想知道为什么不选B 不是有个短语叫做be determined to do sth决心做某事吗?为什么这里要用-ed,而不用-ing 应该是主语he决心做某事,该用主动,就用ing表示伴随状语啊.为什么不用这个呢?》
对了 还有一个问题after ____seems to have been hours.A what B it,C which D that.为什么要选择what呢?(what的这个问题 好像懂一点点了,但是being determined to do something 和determined to do something还是没讲清楚啊,既然是主语he决定的,是主动、那么为什么非谓语不用ing形式也就是being determined to do 而要用过去式也就是determined to do的形式呢?)
he left his homeland_____never___come back again.
确实有be determined to do sth,但是也有determine(动词) to do sth,句子前面已经有left作谓语,所以分句中用determined(过去式)做非谓语.所以是determined to do sth.
用what 为名词性从句的引导词,并非先行词,先行词只在定语从句中出现.
what 在从句中为一个成分,其它的选项都并非句子的成分.
