几道高中状语时态题解析
1.It ________he returns to his native land.中为什么填won`t be long before,而不是will be long since?
2.She was so angry at all____he was doing____she walked out,and closed the door.中为什么填that 和that,而不是that和which?
3.He has been in hospital____he had his right leg broken last month.中为什么填since而不是because?
4.you can`t go swimming in your holiday______ your parents_____you to.中为什么填unless和allow而不是unless和agree?
1 since前应该接完成时态.
这个是网上找的,可供参考
注意区分since,that,when与before的用法!
It was (not ) + 时间段+before + 一般过去时 过了一段时间就……..
It will (not )be+ 时间段+before + 一般现在时 要过一段时间才会…
It is/ has been +时间段+ since…..
It was +点时间+ when…..
It was +时间状语+ that …..(强调句)
1).It was not long before he sensed the danger of the position.不久他就意识到他处境危险(动作已发生)
2).It will be half a year before you graduate from the school.还有半年你才从这个学校毕业(动作未发生)
3).It is 3 years since he worked here.=he left here.(since从句中的谓语动词若是延续性动词,要从这个动作结束的时候算起)
4).It was 3 o’clock when they received the telephone.
5) It was at 3 o’clock that they received the telephone.
2 第一个that,是all that=what,第二个that是与固定词组 so...that
3 可参考第1是题,完成进行时表示动作的延续,一直,用because前面主句用一般时态
4 agree 是赞同的意思,意见达成一致,allow是允许,从词义上就可以区别
