Question

请批评指正1,He is strong enough ___ (carry) the heavy box .答:to c

Answer 1

1.to carry 不能用for carrying

解析：固定搭配be enough to do sth 足够能做‘‘‘‘

2．not to go

解析：tell sb (not)to do sth告诉（叫）某人（不要）做某事

3．To learn

解析：其实这句的原式为It is very important to learn a foreign language well.只不过是把动词不定式to learn a foreign language well 提前在句首了（此时应把It去掉,因为It在原式中只充当to learn a foreign language well的形式主语,不做任何成份）．

4．to play 不能用playing

解析：固定搭配be happy to do sth 做某事很快乐

也有be happy with sth/sb 对某事(人）感到高兴
