the first thing is
问题描述:
the first thing is
像这种句子后加什么形式?属于什么从句?
我是说 the first thing is to do还是doing?为什么?
I found it difficult______(remember)now.
为什么不是I found it is difficult……
答
the first thing is to do 是固定搭配,
第一件要做是事,还没有做,不定式表示将来时
I found it difficult to remember(remember)now.
it 是形式主语,
不定式to do sth 是真正的主语 也是固定用语
