Question

My mother always keeps me________the homework late into the night．

1. A.
   to do
2. B.
   doing
3. C.
   do
4. D.
   to doing

Answer 1

B
分析：keep用非谓语动词作宾语补语时，只能用doing形式，意思是“让某人一直做某事”。(延伸)keep可以用形容词作宾语补语，如：We must keep our classroom clean．以形容词作宾语补语时的意思是“让……保持处于……状态”，而keep用doing作宾语补语时是指“让……一直做……”。看下面这句中该用什么：He always keeps the windows of his bedroom(open／opening)while he is asleep．如果你选opening的话就错了，这是因为keep the windows opening意思是“让窗户一直做开的动作”，窗户不是自己做“开”的动作的，而且也不能“一直开”，所以这里应该是表示“开着的状态”，用形容词open．
