一般过去时表现在
(1)在宾语从句中,由于时态呼应的关系,可用一般过去时表示现在:
I didn't know you were here.我不知道你在这儿。(were实际上指现在)
I didn’t know you were so busy.我没想到你这么忙。(were实际上指现在)
(2)表示客气委婉的现在:
I wonder if you were free this evening.不知您今晚是否有空。
I thought you might like some flowers.我想您也许想要些花。
【注】能这样有的动词主要限于want,wonder,think,hope,intend等少数动词。
(3)用于某些特殊结构中表示现在
It’s time we started.我们该动身了。
I wish I knew his name.要是我知道他的名字就好了。
I’d rather you lived closer to us.我希望你能住得离我们近点。
【注】该用法主要用于it’stime,Iwish,I’drather,ifonly,asif,asthough等少数结构后接从句的情形,其中有些结构后面的句子还可用一般过去时表示将来:
I’d rather you come next Monday.我宁愿你下周星期一来。
另外表主观想法的虚拟条件句也用一般过去时表示现在:
If I had the money now I’d buy a car.假若我现在有钱,我就买辆小汽车。
