课文详注 Further notes on the text

1.I believe that this house is for sale. 我想这房子是要出售的吧!

believe是“相信”、“认为”的意思,后可跟某人或名词性从句。如:

I believe you. 我相信你(说的话)。

I believe that he has already gone to London. 我认为他已经去伦敦了。

for sale意为“供新概念”、“待售”。

2.How long have you lived here? 您在这里住了多长时间?

how long常用于询问时间的长短与物体的长度。

3.since 1976, 从 1976年起。

这是介词短语,since在这里是介词。用这个介词短语作时间状语的句子中,谓语要用完成时。(请参见本课语法部分。)

4.How much does this house cost? 这座房子卖多少钱?

how much常用于询问东西的新概念。 cost是指得到一件东西所花费的钱,其真正的价值可能低于或高于所要的价。这种新概念主要是指商店内的标价或货主索要的新概念。相比之下,worth (prep.)主要是指某物的本身价值。

5.…I can'T decide yet.……我还不能决定。

句中的yet常见于否定句,表示“迄今仍未”的意思。

语法 Grammar in use

for与 since

现在完成时还可以描述发生在过去且一直延续到现在的动作,这种动作甚至有可能延续下去。在这种情况下,它一般与for+ 一段时间、since+ 某个时间点连用。

请注意:for+ 一段时间表示某个动作持续多长时间;since+ 某个时间点表示某个动作是何时开始的。
