三道高一英语分词和时态的选择题,高手帮下忙,每题写下理由.

______very waek,Linda can't move; she has to lie in bed all day.
A.Being B.To be C.Having beeen D.Be
---Why were you absent from the meeting?
---I___ for a long-distance call from my sister in Australia.

Answer 1

1.____ the traffic light turning green,the boy quickly walked across the road.
A.Seeing B.Having seen C.Saw D.See
答：A
译：见到交通灯由红变绿,那男孩很快走过马路.
析：考非谓语动词作状语,排除CD.
AB的区别：A表示两个动作几乎同时发生,相当于：When he saw.../ As soon as he saw...,
B.强调两者有先有后,相当于：After he saw ...,从语境看,选A较好.
2.______very weak,Linda can't move; she has to lie in bed all day.
A.Being B.To be C.Having been D.Be
答：A.
译：由于身体虚弱,琳达起不来,所以不得不整天躺在床上.
析：考非谓语动词作状语,排除D
不定式表示目的,不合句意,排除B
be为状态动词,可以延续.其完成式是延续用法,后应跟一段时间才完整：Having been ill for a long time,.,
而A.Being very weak,.只表示原因,在时间上是同时的关系=As she was very weak,...
3.---Why were you absent from the meeting?
---I___ for a long-distance call from my sister in Australia.
A.wait B.was waiting C.had waited D.waiting
答：B
译：你为什么不来开会?
我（当时）在等我澳大利亚的姐姐的长途电话.（评：这也是理由?）
析：本对话考查时态和对句子的理解.问的是过去发生的情况.比如说刚才,一个小时之前,甚至有可能是昨天下午的事,开会时不见对方.再次见面时,责问对方：你为什么开会时不在?
回答的人要解释当时没去开会的原因.D不是谓语动词,直接排除.A.是现在时态,也可以排除.C.是一个好的干扰项,过去完成时,很多TX以为就是表示“过去做过的事”.其实过去完成时是表示过去某个时间之前发生的事,必须有一个过去的时间作参照,表示某事在这个时间之前就发生了.本题显然不是想说：我在开会之前已经等过长途电话了.排除C
B表示你们开会的期间,我在等长途电话.(大概这会不长,而这长途电话又很重要,此对话很可发生在上世纪,手机还没有的年代!不知道出题者是多大年纪的一个人!）
