  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 wondered 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’s time, I wish, I’d rather, if only, as if, as though 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。
