1. 成分的省略

①在時間、地點、條件、讓步、方式等狀語從句中，如果主語是it或與主句的主語一致，且謂語動詞含有be時，可把從句的主語和be一起省略。

Don’t speak until (you are) spoken to.

Do come to see me whenever (it is) possible.

②在比較狀語從句中，可省略與主句相同的部分。

I know you more than he (knows you).

Tom is two years older than Alice (is).

③as(盡管)引導(dǎo)讓步狀語從句，表語前的冠詞要省略。

Hero as he is, he has shortcomings.

④其他省略。

Please drop in any time you like.

Is it going to rain? If so, I’ll stay at home; but if not, we will go out.

2. 時態(tài)的替代

①在時間、條件和讓步狀語從句中須用一般現(xiàn)在時替代一般將來時，用一般過去時替代過去將來時。

If it rains tomorrow, we won’t go fishing.

Don’t get off the bus until it has stopped.

②The more…the more…句型中，前句起“條件狀語從句”作用，故用現(xiàn)在時表將來。

The harder you work, the greater progress you’ll make.

③after, before, as soon as等連詞本身就暗示了時間的先后，因此可用一般過去時代替過去完成時，而不會產(chǎn)生時間上的混亂。

I went to bed after I (had) finished my homework.

The film star (had) left before the reporter arrived.

He got down to work as soon as he (had) go to the factory.

3. 語序的倒裝

①no sooner…than…, hardly/scarcely/barely…when…句型中的主句常用過去完成時，從句常用一般過去時，且置于句首時主句要倒裝。

No sooner had he got home than it began to rain.

②so/such…that…, not until…置于句首時主句要倒裝。

So angry did she feel that she couldn’t speak.

Not until he told me the truth did I realize what had happened.

4. 連詞的辨析。根據(jù)上下文的語意推斷屬于哪種狀語從句，然后選擇連詞。

把握文章脈絡(luò)，識別句式特點。①把握文章脈絡(luò)，偏重觀點、態(tài)度，慎邊讀邊做。我們在通通覽全文的基礎(chǔ)上，要從整體上把握文脈，找出完形填空短文的主題大意，作者的觀點、態(tài)度，文章展開的線索等信息。②學(xué)好語法知識，積累句型句式。盡管高考淡化語法，注重情景，但是扎實的語法功底，良好的語感對于完形填空題是大有幫助的。

例1：It was pouring outside. We all stood there____, some patiently, others annoyed  because  nature messed up their hurried day. I got lost in the sound and sight of the…

A. chatting           B. waiting            C. complaining    D. talking

[分析]細(xì)讀全文可知，語境為外面下著傾盆大雨，我們站在那里在等雨停下來，不是在干其他事情。

例2： “Tonight was supposed to be____---- to celebrate six months. You do remember we’re engaged, don’t you?”

A. normal            B. sleepless         C. special             D. sad

[分析]本篇文章談?wù)撘粚η閭H的經(jīng)歷，該題易誤選B，認(rèn)為會激動得睡不著，但是結(jié)合語境可知，要慶祝訂婚六個月，所以今晚應(yīng)具有特殊意義。

例3：The story____ to be this: George bought a lottery ticket(彩票) a few days ago and won a prize of $500,000.

A. turned up        B. turned out       C. turned down   D. turned off

[分析]考查常見句式。句意：故事證明是這樣的：喬治幾天前買了彩票獲獎50萬美元。turn out to be “結(jié)果是，證明是”，表示結(jié)果出乎意料之外，四個選項中只有turn out可接to be。

例4：Ellsworth, a patient who had suffered several failures in business, did not show much interest in painting at first. But____ the weeks went by, Swain’s visits grew more  frequently .

A. as          B. with                C. since               D. had to

[分析]分析語境可知，此處意為“隨著時間一周一周過去”。此處不可填with，因為with后不接句子。As time went by “隨著時間推移”，為我們所熟知的句式。

For some time I’ve had a church member provide me with a rose to pin on my suit every Sunday. __1__ I always got a flower on Sunday morning, I really did not__2__ much of it. It was a nice gesture that became__3__. One Sunday, however, what I considered__4__ became very special.

         As I was leaving the Sunday service, a little boy__5__ and said, “Sir, what are you going to do with your flower?” “Do you__6__ this?” I said, pointing to the rose pinned to my coat.

         He said, “Yes sir. I would like it if you are__7__ going to throw it away.” The little boy said, “Sir, I’m going to give it to my granny. My mother and father got_8__ last year. I was living with my mother, but I could not__9__, so she sent me to live with my grandmother. She has been so good to me that I want to give that pretty flower to her for__10__ me.”

         When the little boy finished I could hardly__11__. My eyes filled with tears and I knew I had been touched in the__12__ of my soul. I reached up and__13__ my flower. With the flower in my hand, I looked at the boy and said, “Son, that is the__14__ thing I have ever heard, but you can’t have this flower because it’s not__15__. If you’ll look in front of the platform, you’ll see a big__16__ of flowers. Different families buy them for the__17__ each week. Please take those flowers to your granny because she__18__ the very best.”

         If I hadn’t been__19__ enough already, he made one last statement and I will always treasure it. He said, “What a__20__ day! I asked for one flower but got a beautiful bouquet.”
