问题描述：
These job wanted ___ at once.A.to do B.do C.doing D.to be doing
动词填空：
Nobody likes to ___ (laugh) at.
Every day an old man can be seen ___ (clean) the street in the morning.是cleaning还是to clean?
答
1 laugh 2 cleaning.因为是正在进行时,里面含有被动语态.可不可以再说得清楚点c .这是用主动语态表示被动的典型例题。相当于to be done.类似的动词还有 need第一道动词填空不是被动语态用was laughed吗want，need 习惯用法是用进行时表被动，这时主语是物-_-|||我说的是第一道动词填空不是用被动语态更合适吗？那选项中就应该有 to be done，明白？那就应该是be laughed？前面是to后面跟的是原型
