144题,为什么不可以是busily preparing?
(B)134.Mr Green returned to his office two hours earlier tha
意思都懂 偶就不翻译了
134 expect的对象是green 所以省略了being,用expected,另外这里只是说人家认为他会几点回来 没必要用现在完成式
143 用被动式held没问题吧 省略which was 这是不定式定语从句作表语的一个简化特征 这种中间插入式的描写用定语从句时直接把分词提出来用就可以了
144一样是不定式定语从句做表语,前面用现在式 说明是现在学生们都在学习 用现在进行时 一样用了简略 这种用法是省略了后面半部分前面的部分也成独立句 ;固定搭配 they r busy doing sth=they r doing sth busily
145定语从句提前 前后主语一致 则前部分不用出现主语 b的not的位置意思变成虚拟态 这个么 就是c这个用法 鄙人不晓得怎么解释==!
147 see sb doing 是看到某人在做某事
148 prevent sth (from) doing.from可省略
161 sb is wearing+color=sb is dressed in+color
165 the road leads to=the road is leading to
178彩电的价格下调的话 我们就买一个.前面做条件状语 一般不出现be动词 用动词ing形式代替
