求练习题答案：初中英语中的主动语态变被动语态

Some jewels were found in a box by us。 再问： 我不是叫你帮我改这个句子，是帮我找这个习题的答案，我只是举了其中一个题- - 。 再答： 你说的练习题在哪啊? 我只看到了这一个题。 请说明白一些。再问： 我的意思不是叫你帮我改这一个句子，而是叫你帮我找这个题后面的题，有很多道，然后我要那些题得答案。。。。不懂就继续追问我吧。。。。。 再答： 动句转被动句 1 his mother told him not to waste time on fishing。 2 Father gave me a toy at Christmas。 3 This factory produces machine tools。 4 They should do it at once。 5 He is likely to let you down。 6 They named the child tom。 答案 1 He was told not to waste time on fishing (by his mother)。 2 I was given a toy at Christmas (by my father)。 3 Machine tools are produced in this factory。 4 It should be done at once (by them)。 5 You are likely to be let down。 6 The child was named tom。 以上几个例子都是从语法书摘抄的。代表了几种不同形式的被动变法。1\2是不同的动宾短语中宾语变被动；3是一般句子变被动；4是情态动词变被动；5是不定式变被动；6是主—动—宾—补结构的主动句变被动。
