句型转换,求详解1,he　didn’t go to bed until his wife came back.--- -

1。Not until his wife came back did he go to bed。Not Until 放在开头,主句要倒装,把助动词提前,放在主语he的前面。因为句子的时态是过去式,因此助动词do变成did。2。He persuaded me to attend the club。join=take part in=join in=attend,鉴于题目只有2格,所以填to attend。3。是要填同义句吗?题目意思不明。 再问： 3。 是要填同义句，谢谢 再答： 3。 He made proposals for me to purchase that dress。 / He gave suggestions to me to purchase that dress。 既然这题填的是同义句，那就是把建议advised和buy换一个词。整个句子是过去时，那么动词就要用过去式。advise= make proposals for sb。=give suggestions to sb。，buy=purchase。
