第二篇：狀語從句

Clauses of Condition, Concession and Contrast(條件、讓步和對比從句)條件從句

由 if, unless, as(so)long as, provided / providing(that), suppose / supposing(that), in case等引導，如：

If he comes I'll tell you.You would have succeeded if you had tried harder.You will fail unless you work hard.(=You will fail if you don't work hard.)

Supposing / Suppose it rains, shall we have the match as scheduled?

In case you need anything else, please let me know.讓步從句

由 although, though, even though, even if, whether...or, while, as, wh-words + ever(= no matter + wh-words)等從屬連詞引導，如：

He is quite modest though he is the best student in the class.The needle has the same mass whether it is hot or cold.Whichever(No matter which)plan you adopt, you will meet with difficulties.使用上述讓步從句的某些從屬連詞時注意以下幾點：

a.although(though)不可與連詞 but 連用；

b.as 引導的從句意義和 though 相似，但表示的語氣較強，并須將強調的詞放在句首（但不用 although），如：

Simple as(though)the question may seem, it is not at all common in nature.c.however / no matter how 引導的從句中，however / no matter how 后須緊跟形容詞或副詞，如：

However / No matter how hard I tried, I couldn't remember all the questions.對比從句

表示兩個人或兩件事之間的對比，常用 while 或 whereas 引導，如：

He is idle, while his brother is diligent.Some people like fat meat, whereas others hate it.Clauses of Cause, Result and Purpose(原因、結果和目的從句)原因從句

主要由下列從屬連詞引導：

1． Because, as, since。其中 because 語氣最強，表示直接、主要原因，通常引導的從句放在句尾，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 down.As Mary was the eldest, she looked after the others.Since they live near the sea, they often go sailing.2． 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 travel.Seeing(that)they are just beginners, they are doing quite a good job.I was lucky in that I was able to find a good baby-sitter（保姆）.結果從句

常用 so that, so...that, such...that, that 等連詞引導，如：

I was caught in a shower, so that all my clothes got wet.I was so tired that I could hardly keep my eyes open.He was such a good runner that I couldn't catch him.目的從句

常用 so that, in order(that), lest, for fear that 等連詞引導，如：

I took a taxi so that I could be in time for the meeting.Come closer in order that you may see the blackboard better.so that 既可引導結果從句也可引導目的從句，但結果從句表示事實，通常不含情態(tài)動詞；目的從句表示希望或想要實現(xiàn)的事實，通常含有情態(tài)動詞，如：

He got up early so that he caught the train.（結果）

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，并且從句中動詞須用 “動詞原形”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 wouldn'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，如：

He doesn't speak the way as other people do.Our bodies are made up of millions of very small cells, just as a building is made of many stones or bricks.He speaks French as if(as though)he were a Frenchman.由 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 coming autumn harvest will be even better than the last one.比較從句

主要由 as...as, not so(as)...as, than 等連詞引導，如：

This table is as wide as that one.Mary can not run so(as)fast as Tom.Silver conducts electricity better than other metals.Clauses of Proportion and Other Types(比例從句和其它從句)比例從句

由關聯(lián)詞 the...the...連接形容詞或副詞比較級構成，如：

The more she thought about it, the more she liked it.其它從句

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 man'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。）

第四篇：初中英語——If引導的條件狀語從句

初中英語――if引導的條件狀語從句

引導條件狀語從句最常用的連詞是if，常見的if條件狀語從句表示在某條件下，某事很可能發(fā)生，條件是可能存在的，主句中某種情況發(fā)生的概率也是很高的。如：

If you ask him，he will help you．如果你請他幫忙，他會幫你的。

If you fail in the exam，you will let him down．如果你考試不及格，你會讓他失望的。

If you have finished the homework，you can go home．如果你作業(yè)做完了就可以回家了。

另外，if從句還表示不可實現(xiàn)的條件或根本不可能存在的條件，也就是一種虛擬的條件或假設。從句多用一般過去時或過去完成時，表示對現(xiàn)在或過去的一種假設。如：

If I were you，I would invite him to the party．如果我是你，我會邀請他參加聚會。

I would have arrived much earlier if I had not been caught in the traffic．要不是交通堵塞，我本會來得早一些。另外你還要注意if 條件句的時態(tài)搭配

1．if從句用一般現(xiàn)在時，主句用一般將來時

If he runs，he’ll get there in time.如果他用跑的，他就會及時趕到那兒。

The cat will scratch you if you pull her tail.如果你拉貓的尾巴，它就會抓你。

2．if從句用一般現(xiàn)在時，主句用may/might/can

If the fog gets thicker，the plane may/might be diverted.如果霧在大一些，飛機可能就會改在別的機場降落。If it stops snowing，we can go out.如果雪停了，我們就可以出去。

3．if從句用一般現(xiàn)在時，主句用must/should

If you want to lose weight，you must/should eat less bread.如果你想減肥，你必須少吃面包。

4．if從句用一般現(xiàn)在時，主句用一般現(xiàn)在時

If you heat ice，it turns to water.(也可用will turn)如果把冰加熱，它就會化成水。

5．if從句用現(xiàn)在進行時，主句用一般將來時

If you are looking for Peter，you’ll find him upstairs.如果你是在找彼得，上樓就會找到他。

6．if從句用現(xiàn)在完成時，主句用一般將來時

If you have finished dinner，I’ll ask the waiter for the bill.如果你吃完了，我就叫服務生來算賬

注意 ：

學習“ if ” 引導的條件狀語從句的用法,現(xiàn)在總結一下:

if 條件句不一般,幾個要點記心間;

條件句,放在前,逗號要放句中間。

條件句表可能，主句多用將來時；

條件句表事實，主句常用現(xiàn)在時。

在 if 引導的條件狀語從句中，如果從句談論的是一個有可能發(fā)生的事實及其產生的相關的結果，主句用一般將來時態(tài)，從句用一般現(xiàn)在時態(tài)。如：

We can walk there if we can't find a bus.If it rains tomorrow ,we will not goto the zoo.What will youdo if youfind a panda in danger.如果 if 條件句談論的是重復發(fā)生和預示要發(fā)生的情景和事件，則主從句大多用一般現(xiàn)在時態(tài)。如：If bears are in danger ,they attack people.在 if 引導的條件狀語從句中，if 和條件句位置靈活，可直接放在主句后面，若 if 條件句放句首，從句后面要加逗號，和主句隔開。還要注意前后時態(tài)一致原則
