1 By the end of next term,we _will have finished__(finish) three books.
By the end of next term,说明书未完成．本句的意思是：写完下一章,我们写完3本书了．
所以我认为用将来完成时．
2 When the policeman arrived ,the robber _disappeared
__(disappear) downstairs.
过去时即可．
3 How long _had__ Tom _studied __(study) Chinese before he came to China
因为后半句的是用come 的过去时,故前面用过去完成时had studied
