1、第十二講狀語從句1狀語從句的引導(dǎo)詞與介詞的用法比較；狀語從句與定語從句引導(dǎo)詞的辨析。2能夠辨別同類狀語從句中近似連接詞的用法差異。3whatever，whenever，wherever等引導(dǎo)詞與no matter wh等引導(dǎo)詞的不同用法。2011年高考對條件狀語從句的考查穩(wěn)中有升。2012年考查的重點仍然是考生容易混淆的近似連詞的用法，試題的結(jié)構(gòu)將越來越復(fù)雜，設(shè)問的角度將越來越多樣化。1when, while, as的區(qū)別這三個詞都可以用作連接詞，表示時間關(guān)系，但有所區(qū)別。 (1)when表示時間關(guān)系時，意思常常是“當(dāng)(在)的時候”。主句和從句中的動作或事情可以同時發(fā)生，也可以先后發(fā)生。例如：

2、 When we were at school, we went to the library every day.Ill go when I have had my dinner.The film had begun when we arrived at the cinema.注意：when有哪些通常所在的句型？(2)while 用作連接詞表示時間關(guān)系時，意思也是“當(dāng)(在)的時候”，主句中的動作或事情在從句中的動作或事情的進(jìn)展過程中發(fā)生。它有時可與when通用，但它只能指一段時間(a period of time)，而不能指一點時間的(a point of time)。如上面第一個例句中的w

3、hen，可以用while代替；而第二個例句中的when，就不能用while代替。例如： Please dont talk so aloud while others are working. While I am washing the floor, you can be cleaning the windows.While也可表對比。I like reading while he prefers listening to music.諺語：Strike the iron while it is hot.(3)as用作連接詞表示時間關(guān)系時，意思也是“當(dāng)(在)時候”，往往可與when或while

4、通用，但它著重指主句和從句中的動作或事情相并發(fā)生。例如： I saw him as he was getting off the bus.As he walked on, he felt himself getting more and more tired.As time passes by, we grow older and learn more.As industry develops,more and more farmland has been taken up.2一些表示時間的名詞短語也可用來引導(dǎo)時間狀語從句the minute, the moment, the instant,

5、 every time, the last time, every time。如：The first time I got to the island, I was amazed by its beauty.The moment I entered the room, I smelled something unusual.Every time I visit him, he is always reading.3directly和immediately也可作為連詞，引導(dǎo)時間狀語從句，意為“一就”，相當(dāng)于the moment/the instant和as soon as。如：I knew so

6、mething was wrong directly I arrived. The boys did all sorts of mischief immediately my back was turned.4before 和afterbefore 引導(dǎo)的從句的動作通常發(fā)生在主句動作之后，如果從句是過去時，主句一般要用過去完成時或一般過去時。after引導(dǎo)的從句動作通常發(fā)生在主句動作之前，如果主句要用過去時，從句則要用過去完成時或一般過去時。例如：The plane had taken off before he arrived at the airport. After he had liv

7、ed in the south for nearly 20 years, he decided to go to seek his fortune in the north.They arrived at the cinema after the film began.5no sooner.than 和hardly (scarcely). when這兩個連詞詞組都是表示主句與從句動作隨即發(fā)生，意為“一就”。主句動詞用過去完成時。如果no sooner, hardly 或scarcely位于句首，主句要倒裝。例如：No sooner had he entered the house than i

8、t began to rain.He had hardly gone to bed when the telephone rang.6till 和until這兩個詞的用法十分近似，都表示“直到”，但在句首只能用until。在肯定句中，主句要用延續(xù)性動詞；在否定句中，主句要用非延續(xù)性動詞，這時until和before同義。例如：They did not go home until they had finished the work. They stayed there.7. It 與before, since, when引導(dǎo)的時間狀語從句連用時的區(qū)別：(1)It is/has been時間段s

9、ince . 自從以來已有多長時間了。(2)It is/was時間點when . when 引導(dǎo)的是一個時間狀語從句，主句中的 it 指時間，表語由具體的時間充當(dāng)。常譯為“當(dāng)?shù)臅r候，是”。 (3)It be 時間段 before . it 指時間， 主句中的時態(tài)常是一般將來時或過去時兩種時態(tài)主句中的表語多是long, not long , 3 days , 2 weeks 等表示時間段的詞或短語。常譯為“之后”。例如：How long is it since we met last time?It was a lready midnight when I got home.It was not

15、某一動作或狀態(tài)發(fā)生的地點或進(jìn)行的方向，這類從句通常由where, wherever或 everywhere引導(dǎo)，可以放在主句前，也可以放在主句后，wherever的語氣比where語氣更強(qiáng)烈。where指“在某個地方”，wherever指“在任何一個地方”，everywhere指“每一地方”。例如：Bamboo grows well where it has plenty of rain. Sit wherever you like.Make a mark where you have a question.Where there is a will，there is a way.1. (20

37、C. when D. where【易誤分析】幾個干擾項均有可能誤選?！久麕熤附颉孔罴汛鸢高x D。此題與上面一題有些相似，但又有所不同：相似的是，where 均表示“在的地方”，均用以引導(dǎo)地點狀語從句；不同的是，此題還涉及倒裝，即此句的主語是 the famous tower，謂語是 stood，正常語序為 where the famous tower stood，使用倒裝是為了保持句子平衡，避免頭重腳輕。5.

38、個干擾項均有可能誤選?！久麕熤附颉孔罴汛鸢高x C。when 在此的意思不是“當(dāng)?shù)臅r候”，而是“盡管”、“雖然”的意思。又如：He walks when he might take a taxi. 盡管他可以坐出租車，但他卻走路。He stopped trying when he might have succeeded next time. 盡管他本來下次就可以成功的了，但他卻停止努力了。The boy was restless when he should have listened to the teacher carefully. 這男孩子本來應(yīng)該專心聽老師講的，但他卻坐立不安。有許多同

40、【名師指津】最佳答案選 C。when 意為“這時(突然)”，主要用于某一動作突然發(fā)生于另一動作正在進(jìn)行或剛要發(fā)生之時。此時的 when 可以連用副詞 suddenly，也可以不連用它，但值得注意的是，同學(xué)們不能單獨用 suddenly 來代替 when。7.

A. Ha

42、ving checked B. CheckC. If you check D. To check【易誤分析】幾個干擾項均有可能誤選，尤其可能誤選A?！久麕熤附颉孔罴汛鸢高x C。前面一個分句為條件狀語從句，后面一個分句為主語?，F(xiàn)分析幾個干擾項：選項 A 和 D 均為非謂語動詞，根據(jù)英語語法習(xí)慣，非謂語動詞作狀語時，其邏輯主語應(yīng)與句子主語一致，而此句的 some spelling mistakes 顯然不能用作 having checked 或 to check 的邏輯主語，故不能選為答案；若選 B，則兩個句子之間缺少必要的連詞，也不對。10. “When did he leave the cla

43、ssroom？” “He left_you turned back to write on the blackboard.”A. the time B. the momentC. until D. since【易誤分析】幾個干擾項均有可能誤選?！久麕熤附颉孔罴汛鸢高x B。the moment 用作連詞，意為“一就”，相當(dāng)于 as soon as。類似地，the minute, the instant 也可用作連詞，表示“一就”的意思。1Did you return Freds call?I didnt need to_Ill see him tomorrow.A. thoughB. unles
