1、名校版英语经典句型考点解析介词in和after用法在时间表达上，in和after在表示之后的区别：afterafter可以与时间点或时间段连用，一般不与现在时间发生关系，故常 和动词的过去时或过去完成时连用。请看例句：Two hours later, Jcak came back with an axe.= After two hours, Jcak came back with an axe两小时之后，杰克拿着一把斧头回来了。He goes to work after 7:30.七点半以后他去上班了。She told me she would be here after 6:00.她告诉我她

5、 of poor sales.两年来销路不畅，商店不惜冒起险来。牛津高阶英汉双解词典After years of war, the people long for a lasting peace.历经多年战乱之后，人民渴望永久和平。牛津高阶英汉双解词典通过以上经典例句，小编认为“after可以与时间点或时间段连用，一般 不与现在时间发生关系，故常和动词的过去时或过去完成时连用。”应 该拓展为根据句意需要自由正确选择时态。当然，after还可以表示某个事件、活动等之后，例如：People will visit friends after New Years Day.新年之后，人们会拜访朋 友。T

8、I will go to London in two weeks,我两周之后去伦敦。She will go in three days.她三天以后要走。It will be ready in a weeks time.只需一周的时间就会准备好。She learnt to drive in three weeks.她花三个星期就学会了开车。在in后面出所有格的时候，到底是用s还是s的问题，我们先看 例子：The next train will arrive in five hours time.火车将在 5 小时之后到达。句中，五个小时five hours中hour要加s,后面再跟上time以表

9、达 ”五个小时的时间，这里五个小时的就只加一个撇号一一five hours timeo当然，如果没有time 一词，就直接in five hours；另外，如果不是个 复数时间名词，就只加s,如：in a weeks time = in a week （week是单数,不会影响发音,就加,s）in two weeks time = in two weeks （两周就是个复数词了 weeks,weeks）The next Rugby World Cup will take place in three years1 time.下一届橄榄球世界杯赛将于三年后举行。.牛津高阶英汉双解词典The re

12、（时间段）She came back home after two oclock.她两点钟之后回到了家里。（时 间点）She will come back home after two oclock.他两点钟之后将会回至U家里。（时间点）in five hours 和 in five hours7time真的样吗，最近小编在看英语的过程中看见了不少这样的结构，也有的英语辅导书上说，这两个结构可以通用,果真如此吗？下面小编就来给大家做一个这方面的归纳：1 .当表示各种将来时态的在说话者说话时算起的一段时间以后即在多 长时间以后将做某事的时候，in five hours和in five hours

13、 time 这两个类似结构是可以通用的。这种结构也可以用在祈使句中。The material will be ready in five hours,二 The material will be ready in five hours time.材料将在5小时以后准备好。The bull-fight was to commence in five hours.二 The bull-fight was to commence in five hours time.斗牛将在5小时以后开始。He said the next train would arrive in five hours1 time
