一、時間狀語從句
要點: 時間狀語從句，由以下連詞引導：
when while1 as2 after before as soon as since3 till4 /until5 by the time 在時間狀語從句中，要注意時態一致。一般情況下主句是將來時的時候，從句要用一般現在時。

難點——as when while的辨析
as when while都表示主、從句動作同時發生，三者差異如下：
表示“一邊。。。一邊"的意思
as 強調兩個動作同時進行，並表示對比時
用於發生時間較段時
when 1、還可以表示從句動詞的動作在主幾句動詞的動作"之前 "或"之後"發生。
2、when=and then; at that moment (正在那個時候)
while 1、用於時間較長時
2、 強調兩個動作同時進行，並表示對比時
有時這三個連詞可以互換，有時不可以。
lIt was raining hard when (as) I got there.
我到那裏時，正在下大雨。 ( 動作同時發生，when可換爲as, 但不能換爲while，因爲get是點動詞.)
lWhen I had read the article18, he called me.
我看完這篇文章之後，她給我打了電話。( 從句動作發生在主句之前，注意時態表達，只能用when )
lWhen I got to the cinema, the film had begun.
(當)我到了電影院時，電影已經開演了。(從句的動作發生在主句之後，只能用when,並要注意時態)
lHe was about to leave, when the telephone rang.
他正要離開，忽然電話響了。( 此時不能放在句首。主句動詞一般表達 “正在” “即將”.
while, as不能代替 ) 考點
lShe thought19 I was talking about her daughter, while, in fact20, I was talking about my daughter.
他以爲我在談她女兒，然而，實際上在談論我女兒。(錶轉折，對比，when, as都不能代替它) 考點
lWhile the alien21 was buying a souvenir22, the girl called the police23.
外星人買紀念品時，那女孩給警察打了電話。(表示主句，從句的動作同時發生，while後引導的狀語從句的動詞必須是延續動詞不能是點動詞，因爲它表示較長時間)考點
lMother was worried24 because little Alice was ill, especially25 as (when/ while) father was away.
媽媽擔心，因爲小愛麗絲病了，特別是他父親不在家的時候。(此時as ,when, while可通用)
知識擴展
1. It is since從。。。以來多長時間了(因爲since +從句或名詞，表示一段時間)
It is five years since we met last time.從我們上次見面已經五年了。
2. It is +before…(。。。才)
It was a long time before I went to sleep again.
過了很長時間我才睡着。
It was an hour before(=until) the police arrived.

二、條件狀語從句
要點： 表示狀語從句由連詞if, unless26 (=if not) 引導。

如果你努力學習,就會取得好成績.
3.I will go to the party unless he goes there too.
我不會去參加聚會的, 除非他也去.(如果他不去,我也不去.)

如果你不馬上走,你將會遲到的.(=If you don’t leave immediately, you will be late.)
難點提示：用條件狀語從句時要注意時態的正確使用,當主句是將來時的時候,從句要用一般現在時.
lHe will not leave if it isn’t fine tomorrow.
一般將來時， 一般現在時
lThey are going29 to have a picnic if it doesn’t rain next week.
一般將來時, 一般現在時 考點
三、原因狀語從句
要點: 由連詞because, since, as引導, 也可由for, now that 等詞引導

2. Since everybody30 is here, let’s begin our meeting31.

4.I asked her to stay to tea, for I had something to tell her.
我請她留下來喝茶,因爲我有事要告訴她.
.難點——because , since , as , for,辨析
在語氣上，because 最重, 表示的是直接理由,回答why 時只能用它. 其次是since, as ,一般不表示原因, 而是表明理由, 進一步說明.(譯爲：由於，既然). for 被認爲是複合句的並列連詞(常用於推斷),表示理由.
四、地點狀語從句
要點: 由連詞where和複合關係詞wherever (=no matter where )引導.
知識擴展
e there is a will , there is a way.
有志者事竟成。(諺語)

4. While she was wondering where to go , she met a policeman.
疑問副詞where後跟不定式,構成不定式短語. 考點
五、目的，結果狀語從句
要點： 目的狀語從句由連詞that, so that, so…that , in order that 引導。
結果狀語從句由連詞( so )that, so…that, such…that, so much/many…that引導。
…that 如此…以至於

科學家的報告很有啓發性，我們感到很興奮。

order that=so that:爲了

不久我們將會讓你知道詳情,以便你們能夠做出安排。(目的)
難點
+形容詞或副詞
+形+a(an)+單數可數名詞
so +many 或few+複數可數名詞 +that
+much或 little+不可數名詞
lso that ,such…that 都可以in order that兩者皆可引導目的地狀語從句和結果狀語從句，
當他們引導目的狀語從句時，從句的謂語裏常常有can, could, may, might, will, would等次。
(見例句 2, 5 )
lso +adj./adv.+ that， such +n.+ that 以上兩種句型都表示結果,其中so爲副詞,後接形容詞，副詞原型，當可數名詞前有many, few;不可數名詞前有much, little修飾時，應採用句型：so many (few, much, little )+n. 。 such爲形容詞, 後只能接名詞。這名詞既可以地可數的，也可以是不可數的。如果這名詞是可數,單數,則必須在名詞前敬愛冠詞a(an). 常見的形式是:such a (beautiful)garden, such(nice)people.
lThe weather is so nice that I’d like to take a walk.
天氣是如此只好,以至於我想去散散步.
lMike is so honest a man that we all believe him.

筆記本太少了,我一本也給不了你.
lIt is such nice weather that I’d like to take a walk.
天氣是如此只好,以至於我想去散散步. 考點
六、讓步狀語從句
要點: 表示讓步的狀語從句由連詞 though, although引導.
難點：
lthough, although當雖然講, 都不能和but連用. Although,(though)…but的格式是不對的.但是他們都可以同yet (still) 連用. 所以thought (although)…yet(still)的格式是正確的.
lWrong: Although he is rich but he is not happy.
Right : Although he is rich, yet he is not happy.
雖然他很富有, 然而他並不快樂.
lRight : Although we have grown up, our parents treat us as children.
Right : Although we have grown up, our parents still treat us as children.
儘管我們已經長大了,可是我們的父母仍把我們看作小孩.
although, though 辨析
although 不能though 那樣用作副詞, 放在句末表示強調時要用even though.
lHe is looking fit, though.
但是,他看上去很健康. 考點
lEven though I didn’t under a word, I kept smiling.
儘管我一個字也不懂，我還是一直微笑着。
lHe is quite experienced1, he is young, though.
