Question

My family consider ——a computer,which is considered ——a great help in our work and study.
A.TO buy ,to be B.buying ;being C.buying;to be 我知道make sb do 变成被动的话是be made to do
但我问过初中老师 有动词+doing 的话被动是be +动词被动形式+doing 的...
但这一题不是是 considere doing吗 按初中老师说的话被动是be considered doing
问 have sb do 和have sb doing 怎么变被动.

Answer 1

此题与have sb do 和have sb doing 一点不沾边.
答案: C. buying;to be
第一空考查: consider doing sth. 考虑做某事
第二空考查: be considered to be... 这是固定搭配,与be considered as同义.意为" 被认为是..."
have sb do 和have sb doing 怎么变被动? 这种情况我从来没见过, have 作使役动词时,一般用主动语态,不用被动语态的. 倒是make作使役动词时有被动语态.如:
The boss made him work nine hours a day .
He was made to work nine hours a day by the boss.
