華南師范大學(xué)附屬中學(xué)
由從句擔(dān)任的狀語,在句子中可修飾謂語(或其他動(dòng)詞)、形容詞、副詞或是整個(gè)句子,它可以用來表示時(shí)間、地點(diǎn)、原因、目的、結(jié)果、條件、方式、比較、讓步等。狀語從句是一較大的語法項(xiàng)目,也是近幾年高考題中常見的一個(gè)重要試點(diǎn)。高考中已考查了時(shí)間、讓步、地點(diǎn)、條件、目的等狀語從句,這些從句仍是今后高考熱點(diǎn),應(yīng)作充分準(zhǔn)備。同時(shí)對(duì)方式狀語從句也應(yīng)引起重視。
一、時(shí)間狀語從句
表示時(shí)間的狀語從句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner …… than, hardly (scarcely) …… when, every time等引導(dǎo)。
e.g. When I came into the office, the teachers were having a meeting.
He started as soon as he received the news.
Once you see him, you will never forget him.
No sooner had I gone to bed than I went to sleep.
二、原因狀語從句
原因狀語從句是表示原因或理由的,引導(dǎo)這類從句的最常用的連詞是because, since, as , now that(既然)等,for 表示因果關(guān)系時(shí)(它引導(dǎo)的不是從句)為并列連詞,語氣不如because強(qiáng)。
e.g. He is disappointed because he didn't get the position.
As it is raining, I will not go out.
Now that you mention it, I do remember.
三、地點(diǎn)狀語從句
引導(dǎo)地點(diǎn)狀語從句的連詞是where 和wherever等。
e.g. Sit wherever you like.
Make a mark where you have a question.
