新概念英语教材详解:第一册 Lesson89-90
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
