1.B 时间状语从句中不能出现will.until 引导的是时间状语从句.B选项表示现在完成时,表示“我已经看完了再借给你”A 是一般将来时态,B是现在完成时 C是一般现在时,情态动词用法,D 是将来完成时.
2.C 这句话的意思是:“海伦把钥匙落到家里了,所以不得不等到他丈夫回来.整个句子的时态基调是过去时态,而落钥匙的动作发生在“had to wait ” 之前,就是过去的过去,所以要用过去完成时had left ,而“丈夫回家”与主句“she had to wait "时态保持一致,用一般过去时态
3.D 意思是“中央电视台自从1977年就已经广播英语节目了” A 1 若看成一般现在时,要用单三形式,而且句子是从过去就开始了,所以用法和时态都不对 2 若看成一般过去时,因为有ever since 要用完成时态,也不合适.B 是过去进行时,表示过去发生的某一动作正在进行,与句意不符合.C现在完成时的被动语态,句意不通,播放的就是CCTV,不用被动,若改成had been broadcasting 现在完成进行时则可以了.D 选项现在完成时,表示动作发生在过去,但一直延续到现在,句意也符合
4.D suggest 的用法 suggest doing sth 否定形式是suggest not doing sth 选D
5.C B是现在完成时,D是过去完成时,A 是一般过去时,C 是过去进行时.last year 去年,是典型的过去时态标志,只表示过去,没有完成之意,所以排除BD 但由于后半句“但是我不知道是否她已经写完了”限定,可以推知 “去年Lisa 正在写”要比单纯陈述“Lisa 去年写了”更好,所以选C ,而不选A
希望对你有所帮助
1.B 2.C 3.D 4.D 5.C
B 将来时 前面已经有了won't后面不能在用will
C 句子的谓语是had to 是过去式,证明他将钥匙锁在家里是发生在谓语动作之前,俗称过去只过去,所以只能用had left. until后面保持过去式不变
D since 是完成时的一个标准,排除AB,此句五被动语态,排除C
C sugest 表示建议的时候要用省略should的虚拟语气,should 后面加动词原形...

B 题中的不知道有没有完成是关键提示语,完成时表示动作的一个延续,从过去到现在,也许还要延续到将来,之所以不选D因为他必须有过去之过去的时间才能用过去完成时
