a. In the museum there are a lot of interesting things look at.
b. I am looking forward to see you.
正确的句子:
a. In the museum there are a lot of interesting things to look at.
b. I am looking forward to seeing you.
分析:
a句中己有谓语动词there are,用来修饰things,此句缺的是后置定语。b句look forward to是一个固定短语,后面要接动名词。c句要用现在分词作定语,跟所修饰的名词之间是主谓关系,表示动作正在进行,因此用“sleeping”,相当于 “the child who is sleeping"。
