to 后是否可以加情态动词
English is very useful and we must learn it well .(改为同义句)
It is____for us ____ _______ _________English well.
useful to must learn
to后面可以跟 must 如果可以,是从语法上分析,还是有这样的句子,希望可以将类似这种情况的句子举出来.
如果不能,那么请做出这道题的正确答案
to 后是否可以加情态动词English is very useful and we must learn it well .(改为同义句)It is____for us ____ _______ _________English well.useful to must learn to后面可以跟 must 如果可以,是从语法上分析,还是有这样的
to 只有两种可能,1.是介词,后面跟名词、代词和动名词.
2.是动词不定式的小品词,即构成to do 这个结构,此时后面只能跟动词原形.
因此不可能跟must.
上面的题目我认为后面多了一个空格,只要填useful,to learn 就行了.
要不多了一个空 It is useful for us to learn English well 要不少了一个空 It is useful for us,so we must learn English well to 后不可能接情态动词
