【正文】 istakes.)Clauses of Manner and Comparison(方式和比較從句)方式從句主要由 just as, as, as if, as though 等連詞引導，如：He doesn39。t speak the way as other people bodies are made up of millions of very small cells, just as a building is made of many stones or speaks French as if(as though)he were a as if 或 as though 引導的從句通常用虛擬語氣，但如果主句謂語是感官動詞，并且所述情況實現(xiàn)可能性大，也可用陳述語氣，如：It looks as if the ing autumn harvest will be even better than the last 主要由 as...as, not so(as)...as, than 等連詞引導，如：This table is as wide as that can not run so(as)fast as conducts electricity better than other of Proportion and Other Types(比例從句和其它從句)比例從句由關(guān)聯(lián)詞 the...the...連接形容詞或副詞比較級構(gòu)成，如：The more she thought about it, the more she liked 如 as...so 和 what...that 引導的類比從句；so(as)far as 引導的范圍從句；except that 引導的例外從句；rather / sooner than 和 would / had rather than 引導的擇比從句等，如：As the desert is like a sea, so is the camel like a ship.（沙漠似海，駱駝似舟。）What blood vessel is to a man39。s body, that railway is to transportation.（鐵路對于運輸，好比血管對于人的身體。）As(So)far as I know, he is an honest man.（據(jù)我所知，他是一個誠實的人。）I would do it with pleasure, except that I am too busy.（要不是我太忙了，我會很高興去做的。）Rather than get money in such a dishonest way, he would beg in the streets.（他寧可沿街乞討，也不愿意用欺騙手段騙取錢。）He would rather have the small one than the large one.（他寧可要那個小的，而不愿要那個大的。）第三篇：狀語從句1狀語從句一：什么是狀語從句？用一個句子(從句)來作另一個句子(主句)的狀語，用作狀語的句子就叫作狀語從句。作什么樣的狀語就叫什么類型的狀語從句。例如：條件狀語從句就是用一個句子來作條件狀語。二：狀語從句的分類。凡是從句都必須有引導詞，引導時間狀語從句的詞有 when, before, after, until, as soon as, while 等，具體用法如下：（1）.when 意為“當??時”，引導時間狀語從句，表示主句的動作和從句的動作同時或先后發(fā)生。例如：I feel very happy when you e to see （們）來看我時，我感到很高興。When you are crossing the street, you must be （們）過街道時，一定要小心。when引導的時間狀語從句，when的從句可以用延續(xù)性動詞，也可以用點動詞。He was working at the table when I went ，他正在桌旁工作。Someone knocked at the door when I was ，有人敲門。I will visit my good friend when I have ，我將去看望我的好友。I worked for a foreign pany when I was in ，我為一家外國企業(yè)工作。注：when也可以作并列連詞，表示一個動詞正在進行的時候，突然間發(fā)生了另外一件事。I was fishing by the river , when someone called for ，就在那時有人求救。We were working in the chemistry lab, when the lights went ，突然燈都熄滅了。比較while, when, as1）as, when 引導短暫性動作的動詞。Just as / Just when / When I stopped my car, a man came up to ）當從句的動作發(fā)生于主句動作之前，只能用when 引導這個從句，不可用as 或 while。When you have finished your work, you may have a ）從句表示“隨時間推移”連詞能用as，不用when 或while。As the day went on, the weather got ，天氣越變越壞。（2）.before 意為“在??之前”，引導時間狀語從句時，表示主句的動作發(fā)生在從句的動作之前。例如：We cleaned the classroom before we left school ，我們打掃了教室。He had been a cook before he went to 。after 意為“在??之后”，引導時間狀語從句時，表示主句的動作發(fā)生在從句的動作之后。例如：After you use plastic bags, you mustn39。t throw them （們）用過了塑料袋之后，不準到處亂扔。He called me after he had finished his 。注：若主句和從句兩個動作發(fā)生的先后順序十分接近，那么也可以不用完成時態(tài)，例如 1上面的第二句可改成：He called me after he finished his work.（3）.since引導的時間狀語從句，譯為“自從??”，主句常用現(xiàn)在完成時，從句常用一般過去時。We have made many dumplings since we began to ，我們已經(jīng)包了許多餃子了。We haven39。t seen each other since we 。注：常用句型：It is +時間段+since從句譯為：自從??有多長時間了。It is six years since she graduated from the 。（4）.until 意為“直到??時”，引導時間狀語從句時，表示主句的動作發(fā)生在從句的動作之前。當主句的謂語動詞是持續(xù)性動詞時，主句常用肯定形式；當主句的謂語動詞是非持續(xù)性動詞時，從句常用否定形式, not...until...意為“直到??才??”，這時的until可以用before 來替換。例如：I39。ll stay here until you e ，直到你回來。(stay表示的動作可以持續(xù))He didn39。t go to bed until he finished his 。(go to bed 表示的動作不能持續(xù))（5）表示“一?就?”的結(jié)構(gòu)hardly/scarcely?when/before, no sooner?than 和as soon as都可以表示“一?就?”的意思，表示從句的動作一發(fā)生，主句的動作馬上就發(fā)生。例：①、I39。ll tell him about it as soon as he es 。②、I had hardly / scarcely got home when it began to rain.③、I had no sooner got home than it began to rain.④、As soon as I got home, it began to ：如果hardly, scarcely 或no sooner置于句首，句子必須用倒裝結(jié)構(gòu)：Hardly / Scarcely had I got home when it began to sooner had I got home than it began to rain.（6）.while引導的時間狀語從句，常譯為“與??同時，在??期間”，while的從句中常用延續(xù)性動詞或表示狀態(tài)的詞。They rushed in while we were discussing ，他們沖了進來。Father was cleaning the car while I was playing puter ，爸爸正在清洗汽車。注：while也可以作并列連詞，表轉(zhuǎn)折的關(guān)系，相當于but，譯為“然而”。 like listening to music, while my brother likes doing ，而我的兄弟愛好運動。（7）.till和until引導的時間狀語
