Look at these pictures and match the order.2. Give the students the following matching exercise to do , to familiarize them with adverb clauses on board, omitting the underlining which is given here for your referenceStep Two Presentation Explain the rules of the adverb clause 1時間狀語從句的連詞 表示時間的連詞有when, while, as, by the time, before, after, since, till/until, as soon as，有些名詞短語也可以引導(dǎo)時間狀語從句，如the moment, the instant, each time，有些是固定句型如：no sooner than hardly/scarcely when。在這些連詞的使用中應(yīng)注意 as強(qiáng)調(diào)同時，也表示"一邊，一邊"，while表示主句動作發(fā)生在從句的過程之中，要求從句謂語動詞為狀態(tài)動詞或持續(xù)性動詞，when的使用則比較簡單，相當(dāng)于漢語的"當(dāng)時候"。如： Doing your homework is a sure way to improve your test scores, and this is especially true _ it es to classroom tests. A.when B.since C.before D.after 四個選項都表示時間，但根據(jù)主從句間的關(guān)系可以判斷答案 為A。 注意when的特殊句型 下列句型中when連接的不是時間狀語從句，但考試中卻常與其它時間狀語從句的連詞一塊出題。 were/was doing something when were/was about to do something when had just done something when I had just started back for the house to change my clothes _ I heard voices. A.as B.when C.after D.while I felt somewhat disappointed and was about to leave _ something occurred which attracted my attention. A.unless B.until C.when D.while 注意no sooner than .和hardly/scarcely when句中的時態(tài)。 注意not until 中時間狀語可以提前。如 _ quite recently, most mothers in Britain did not take paid work outside the home. A.Before B.Until C.From D.Since 但只要同學(xué)們能夠辨認(rèn)not until 的句法結(jié)構(gòu)，答案也就顯而易見。 比較常見的提前方式是將not until.提至句首，后面用肯定形式，主謂倒裝。本題可以改成，Not until quite recently did most mothers in Britain take paid work outside the home.這時，句子采用主謂倒裝結(jié)構(gòu)，應(yīng)注意。 在對名詞短語做連詞引導(dǎo)時間狀語從句時，常與名詞構(gòu)成的其它短語相區(qū)別。如： You see the lightening _ it happens, but you hear the thunder later. A.the instant B.for an instant C.on the instant D.in an instant 能夠引導(dǎo)時間狀語從句的是名詞the instant，而不是由其構(gòu)成的介詞短語。 注意含有時間狀語從句的固定句型，如It won't be long before 和It is since兩類句型。It won't be long before可以有三個變體，即：It was (not) + 一段時間 + before，It won't be + 一段時間+ before。Scientists say it may be five or ten years _ it is possible to test this medicine on human patients. A.since B.before C.after D.when 2原因狀語從句的連詞 原因狀語從句一般由because, since, as, now that, considering that, seeing that連接。對于表原因連詞本身的區(qū)別考查相對較少，主要是與其它狀語從句連詞的對比。如： _ you are leaving tomorrow, we can eat dinner together tonight.A.For B.Since C.Before D.While _ that my head had cleared, my brain was also beginning to work much better.(1997.6) A.For B.Now C.Since D.Despite 1) 從以上兩題可以看出，首先，同學(xué)們要根據(jù)主從句的語意關(guān)系，確定是什么狀語從句，然后在進(jìn)行選擇。 2) 注意連詞的結(jié)構(gòu)，如2）為Now that的搭配。 3) 注意for, because, since/as的區(qū)別。一般說來，for不表示原因，其所連接的是并列句，是一種解釋說明，尤其是當(dāng)用結(jié)果來反證原因時。如： He must have experienced something very unpleasant, for he looks so upset. You must try to rid yourself of your carelessness, for it often leads to errors. 4) 注意引導(dǎo)原因狀語從句的還可以是considering/seeing that，其用法與since/as相同。如： Considering that he is only a beginner, it is understandable for him to make such mistakes. Seeing that you have e, you may as well stay here for a few days.
