【正文】 cceeded if you had tried will fail unless you work hard.(=You will fail if you don39。t work hard.)Supposing / Suppose it rains, shall we have the match as scheduled?In case you need anything else, please let me 由 although, though, even though, even if, whether...or, while, as, whwords + ever(= no matter + whwords)等從屬連詞引導(dǎo)，如：He is quite modest though he is the best student in the needle has the same mass whether it is hot or (No matter which)plan you adopt, you will meet with ：(though)不可與連詞 but 連用； 引導(dǎo)的從句意義和 though 相似，但表示的語氣較強(qiáng)，并須將強(qiáng)調(diào)的詞放在句首（但不用 although），如：Simple as(though)the question may seem, it is not at all mon in / no matter how 引導(dǎo)的從句中，however / no matter how 后須緊跟形容詞或副詞，如：However / No matter how hard I tried, I couldn39。t remember all the 表示兩個(gè)人或兩件事之間的對(duì)比，常用 while 或 whereas 引導(dǎo)，如：He is idle, while his brother is people like fat meat, whereas others hate of Cause, Result and Purpose(原因、結(jié)果和目的從句)原因從句主要由下列從屬連詞引導(dǎo)：1． Because, as, since。其中 because 語氣最強(qiáng)，表示直接、主要原因，通常引導(dǎo)的從句放在句尾，特別是回答 why 提出的問題只能用 because。as 和 since 表示明顯的、已知的原因，since 比 as 正式，如：They had to move because their building was to be pulled Mary was the eldest, she looked after the they live near the sea, they often go ． now that, seeing(that), considering(that), in that。這些連詞與 as, since 意思相近，通常用于書面語，并且它們兼有其它意義。now that 有“時(shí)間”含義，表示”既然”，說明一種新情況；seeing(that)和 considering(that)有“條件”含義；in that 有”某一方面”含義，如：Now that you are well again you can (that)they are just beginners, they are doing quite a good was lucky in that I was able to find a good babysitter（保姆）.結(jié)果從句常用 so that, so...that, such...that, that 等連詞引導(dǎo)，如：I was caught in a shower, so that all my clothes got was so tired that I could hardly keep my eyes was such a good runner that I couldn39。t catch 常用 so that, in order(that), lest, for fear that 等連詞引導(dǎo)，如：I took a taxi so that I could be in time for the closer in order that you may see the blackboard that 既可引導(dǎo)結(jié)果從句也可引導(dǎo)目的從句，但結(jié)果從句表示事實(shí)，通常不含情態(tài)動(dòng)詞；目的從句表示希望或想要實(shí)現(xiàn)的事實(shí)，通常含有情態(tài)動(dòng)詞，如：He got up early so that he caught the train.（結(jié)果）He got up early so that he could(might)catch the train.（目的）Lest 和 for fear(that)含有否定意義，并且從句中動(dòng)詞須用 “動(dòng)詞原形”或 ”should + V.” 的虛擬語氣，如：He ran away lest he(should)be caught.(= He ran away in order that he would not be caught.)I checked all the results time and again for fear that there should be any mistakes.(= I checked all the results time and again so that there wouldn39。t be any mistakes.)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(dǎo)，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(dǎo)的從句通常用虛擬語氣，但如果主句謂語是感官動(dòng)詞，并且所述情況實(shí)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(dǎo)，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(jí)構(gòu)成，如：The more she thought about it, the more she liked 如 as...so 和 what...that 引導(dǎo)的類比從句；so(as)far as 引導(dǎo)的范圍從句；except that 引導(dǎo)的例外從句；rather / sooner than 和 would / had rather than 引導(dǎo)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(duì)于運(yùn)輸，好比血管對(duì)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(gè)誠(chéng)實(shí)的人。）I would do it with pleasure, except that I am too busy.（要不是我太忙了，我會(huì)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(gè)小的，而不愿要那個(gè)大的。）第三篇：狀語從句講解+練習(xí)(導(dǎo)學(xué)案)狀語從句學(xué)習(xí)目標(biāo)：、記憶，記住狀語從句的考點(diǎn)、講解，會(huì)用狀語從句的知識(shí)解決問題。由從句擔(dān)任的狀語，在句子中可修飾謂語（或其它動(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)。 I came into the office, the teachers were having a started as soon as he received the you see him, you will never forget 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)。 is disappointed because he didn39。t get the it is raining, I will not go 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。 wherever you a mark where you have a question.（四）目的狀語從句引導(dǎo)目的狀語從句最常用的詞（組）是so, so that（從句謂語常有情態(tài)動(dòng)詞）, in order that, in case（以防，以免）等。 clearly, so that they may understand has bought the book in order that she could follow the TV left early in case he should miss the train.（五）結(jié)果狀語從句結(jié)果狀語從句是表示事態(tài)結(jié)果的從句，通常主句是原因，從句是結(jié)果。由so that（從句謂語一般沒有情態(tài)動(dòng)詞）, so … that, such … that等引導(dǎo)。 was ill, so that she didn’t attend the was so excited that he could not say a is such a good teacher that everyone admires her.（六）條件狀語從句條件狀語從句分真實(shí)性（有可能實(shí)現(xiàn)的事情）與非真實(shí)性（條件與事實(shí)相反或者在說話者看來不大可能實(shí)現(xiàn)的事情）條件句。引導(dǎo)條件狀語從句的詞（組）主要有if, unless, so(as)long as, on condition that, so(as)far as, if only(= if)。注意：條件從句中的if 不能用whether替換。 he is not in the office, he must be out for may borrow the book so long as you keep it far as I know（據(jù)我所知）, he will be away for three can go swimming on condition that(= if)you don’t go too far away from the river he had e a few minutes earlier, he could have seen her.（七）讓步狀語從句讓步狀語從句可由although, though, as, even if(though), however, whatever, whether … or, no matter who(when, what, …)等引導(dǎo)。注意：as引導(dǎo)的讓步狀語從句一般是倒裝的。 he is a child, he knows a as he is, he knows a (= No matter what)you say, I’ll never change my mind.（八）方式狀語從句方式狀語從句常由as, as if(though), the way, rather than等引導(dǎo)。 must do the exercise as I show acted as if nothing had happened.（九）比較狀語從句比較狀語從句常用than, so(as)… as, the more … the
