Question

1We were looking for the lost wallet in the street when the clock (struck) 10:00 2 The actress told the tailor that he must (make) her dress (to) her own measure 3 The boy I saw just now was not (what） he used to be ten years ago 4（give）blood if you can and many lives will be saved 5There must be a dozen pens in this house but I can never find one when I need one keeping looking (one )is sure to turn up 为什么用括号里面的词和形式

Answer 1

1、We were looking for the lost wallet in the street when the clock (struck) 10:00 .
struck指的是在找到丢失的钱包时,时钟敲10点,指的是这一时刻.
2、The actress told the tailor that he must (make) her dress (to) her own measure .
make在must后面用原型是语法规定的；make ...to one's own measure 是“照某人尺寸做”的意思,属于固定搭配.
3、The boy I saw just now was not (what） he used to be ten years ago.
what是指那个男孩过去的样子,相当于the thing which,不能当多难过that或which.
4、（give）blood if you can and many lives will be saved .
这句话是献尽可能多的血,更多的生命将获救.是祈使句.
5、There must be a dozen pens in this house but I can never find one when I need one,keeping looking (one )is sure to turn up.
one指的是一只钢笔,表示任意一只.且后面是单数形式is.
（我给你提供的句子加上标点了,尤其是最后一句,否则一般很难看的懂）
