英语选择题的一些疑惑,望高手解答.
1.julia is going to meet her boyfriend.she————for the bus for some time but it has not come yet.为什么填has been waiting而不可以填has waited
2.The policemen entered the building,—————.A、looked about and hurrying upstairs B、looking about and hurrying upstairs C、looking around and to hurry upstairs D、to look around and hurrying upstairs答案是选b,想知道为什么
3、this is the first letter ————he has written in German.
A、in which B、whichC、whyD、that答案是D,想知道为什么
4、We had waited over an hour before the train arrived.We ————out so early without breakfast.A、couldn‘t have set B、shouldn’t started C、might not have set D、needn‘t have started答案选D,为什么.我觉得B、D都可以啊
5、Don’t leave your things ————about when you go out of the bedroom.A、
lying B、lied C、lain D、laying 选A ,为甚?
1.因为她等公交车等到现在都还没有来,而且这个动作还可能持续等下去,所以就必须要用has been waiting.
2.看和上楼都是同时并且伴随着的动作,所以得用现在进行时.
3.首先我们可以看出这题需要一个代词,而that和which都可以的.但是定语从句中,先行词被序数词修饰,关系代词只能用that,不能用which.1) 只能用that作为定语从句的关系代词的情况
a) 在there be 句型中,只用that,不用which.
b) 在不定代词,如:anything, nothing, the one, all, much, few, any, little等作先行词时,只用that,不用which.
c) 先行词有the only, the very修饰时,只用that.
d) 先行词为序数词、数词、形容词最高级时,只用that..
e) 先行词既有人,又有物时.
4.根据句子意思,B和D是都可以的,但是你有没有发现没有B选项少了一个have.
5.根据句子句子意思,我们知道应该是放平躺的意思.B和D就排除了.而lying about, lying around必须是进行时, 因为东西闲置着, 是进行的, 不可能是过去时, 因为他一直闲置在那里.
