例析歷年高考試題歸結(jié)as難點用法

1、例析歷年高考試題 歸結(jié)as難點用法河南 謝奎金來源：2009 年上半年試題與研究單詞as詞形簡單，但用法復(fù)雜，可作副詞、替代詞、關(guān)系代詞、從屬連詞和介詞。還可與其他詞匯結(jié)合構(gòu)成諸多搭配，故as一直是高考熱點，也是廣大考生復(fù)習(xí)備考的難點?，F(xiàn)結(jié)合考題，剖析難點，以饗讀者。一、用作介詞，as與like用法區(qū)別例1 Lets learn to use the problem we are facing _ a stepping-stone to future success.( NMET 2008全國卷)A. to B. for C. as D. by解析 C。as作介詞表“作為”，常接在treat/

2、regard/recognize/use等動詞之后；而like表“像一樣”。試比較：(1)He is a child, and must be treated as such.他年幼，應(yīng)該當(dāng)孩子對待。(2)He acted like a child, while he had grown up.他雖已成人，但做事卻像孩子一樣。二、用作從屬連詞1表時間，as/when/while用法區(qū)別例2 Mother was worried because little Alice was ill, especially _ Father was away in France. (NMET 1994全國卷)

3、 A. as B. that C. during D. if解析 A。主從句動作先后發(fā)生常用when；兩個較長動作同時發(fā)生用while；特別強調(diào)主從句動作同時發(fā)生用as，譯作“一邊一邊”， as還可表“隨著”。另when, while還可用作并列連詞。when表at that time，而while表“兩相對照”。2表原因，as/because/since/for用法區(qū)別例3 Jenny was very sad over the loss of the photos she had shot at Canada, _ this was a memory she especially trea

4、sured. (NMET 2006廣東卷)A. as B. if C. when D. where解析A。as 作從屬連詞引導(dǎo)原因狀語從句。as和because, since, for的區(qū)別是：because語勢最強，用來說明人所未知的原因，回答why提出的問題，可置于強調(diào)句中且其前可加修飾語； since是雙方都知曉原因或經(jīng)過分析而得之的原因，語氣次之；for是并列連詞，前用逗號隔開，表邏輯推理或補充說明；as語氣最弱，原因是顯而易見的或已為人們所知，即已知原因，所引導(dǎo)的分句可置于句首。3表轉(zhuǎn)折，引導(dǎo)讓步狀語從句例4 _, he talks a lot about his favorite

5、singers after class. (NMET 2005重慶卷）A. A quiet student as he may be B. Quiet student as he may beC. Be a quiet student as he may D. Quiet as he may be a student解析 B。as 引導(dǎo)讓步狀語從句時，形容詞、副詞、動詞等常置前；若表語為名詞，前置時使用零冠詞；從句謂語動詞常和助動詞或情態(tài)動詞may, might, will, would等連用。4表正如，引導(dǎo)方式狀語從句例5 Who should be responsible for the

6、accident?The boss, not the workers. They just carried out the order _. (NMET 2008福建卷)A. as told B. as are told C. as telling D. as they told解析A。as引導(dǎo)方式狀語從句，表按照、正如；非限定分句“從屬連詞+-ed/-ing形式” 可以看作是一種省略，即省略了主語和be動詞。究竟使用何種非謂語動詞形式取決于主被動關(guān)系。又如：(1) As I explained on the phone, your request will be considered at

7、the next meeting.（NMET 2005浙江卷）(2)Doctors have said that as many as 40 percent of patients dont take medicine as directed.三、用作關(guān)系代詞，指代整個句子，as/which/it用法區(qū)別例6 The Beatles, _ many of you are old enough to remember, came from Liverpool. (NMET 2006天津卷)A. what B. that C. how D. as解析 D。as作關(guān)系代詞，在非限制性定語從句中，可指

8、代整個句子內(nèi)容，置于句首，而which不可；it為代詞，用作句子成分，但不用來連接句子，故常和并列連詞連用；在限制性定語從句中常與such, the same連用，試比較：(1)I havent many toys but I will send you such as I have.我的玩具并不多。不過，我會把我僅有的一點玩具送給你。(2)The book is not such that I can advise you to read it.這本書并不怎么樣，我沒法向你推介。四、用作從句性替代詞，等同于so例7 My room gets very cold at night._. (NM

9、ET 2007江蘇卷)A. So is mine B. So mine is C. So does mine D. So mine does解析C。從題干中動詞gets得知，助動詞應(yīng)選擇do的適當(dāng)形式，故排除選項A和B；從語序上考慮，排除選項D。as用作從句性替代詞，等同于so，只是用于正式語體中。如：Our eating habits have changed, as has our way of life.五、asas結(jié)構(gòu)1構(gòu)成倍數(shù)比較句型：n times+asas例8 What a table! I ve never seen such a thing before. It is _ i

10、t is long.（NMET 2005湖北卷）A. half not as wide as B. wide not as half as C. not half as wide as D. as wide as not half解析答案C。not與謂語動詞連用構(gòu)成否定。as 作從屬連詞引導(dǎo)比較狀語從句，常見結(jié)構(gòu)為as.as，第一個as為副詞，后接形容詞或副詞，第二個as為連詞。程度修飾語應(yīng)放在第一個as之前。2. as/so long as例9 Have you got any idea for the summer vacation?I dont mind where we go _ th

11、eres sun, sea and beach.( NMET 2008全國卷)A. as if B. as long as C. now that D. in order that解析 B。as long as最基本詞義表示主從句動作延續(xù)時間一樣長，可引導(dǎo)時間狀語從句；若引導(dǎo)條件狀語從句，表“只要”，同only if，為唯一條件。又如：As long as I know the money is safe, I shall not worry about it.（NMET 2003北京卷）3.as far as例10 _ I can see, there is only one possibl

12、e way to keep away from the danger.（NMET 2004北京春季卷）A. As long as B. As far as C. Just as D. Even if解析 B。as far as I knowcan seeam concerned表據(jù)我所知（我看、我所關(guān)心的）；as far as還表“遠(yuǎn)至”。4.as much as例11 The more I think about him, the more reasons I find for loving him _ I did.（NMET 2005湖南卷）A. as much as B. as long

13、 as C. as soon as D. as far as解析A。as much as表程度或數(shù)量；as long as表長度或條件；as soon as盡快；as far as遠(yuǎn)至，根據(jù)。若用于否定句中，第一個as換為so。例：Young people in the US dont care so much about fashion as those in China.5.as well as例12 John plays football _, David. (NMET 1994全國卷)A. as well B. as well as C. so well D. so well as解析

14、B。if not better than為插入語，對考生答題具有一定干擾。as well as在功能上相當(dāng)于并列連詞，用來連接兩個平行成分，但不能用作并列連詞。注意在連接兩個并列謂語動詞時，其后的動詞使用動詞-ing形式；除此之外，所連接的成分前后應(yīng)保持平行、對等。試比較： Computers have been put into robots and _to make mobile phones as well as _with medical operations. (原創(chuàng)模擬)A. used ; to help B. used; help C. using; helping D. usi

15、ng; helped Computers have been put into robots as well as _to make mobile phones and _with medical operations. (原創(chuàng)模擬)A. used; to help B. having been used; help C. being used; helping D. using; helped答案與解析：B；B。中and為并列連詞，used與謂語動詞put保持一致。as well as用來連接兩個并列狀語，作不定式的賓語，故make與help保持一致；中as well as用來連接兩個并列動

16、詞，故緊隨其后的動詞使用-ing形式，并與謂語動詞照應(yīng)，使用having been used形式。其后and為并列連詞，連接并列狀語，作不定式的賓語，保持一致。6.as good as例13 He said he would do whatever he could to help me, and he was _ his word.A. as good as B. as well as C. as much as D. as many as解析A。as good as最基本詞義是“和一樣好”；還可表示“幾乎，簡直是”，其后接名詞、動詞或形容詞均可，在功能上相當(dāng)于副詞very nearly。如

17、：The work is as good as finished.工作基本完成。If he finds out, Im as good as dead.要是他發(fā)現(xiàn)了，我就完了。六、as其他常見搭配1so as to例14 All these gifts must be mailed immediately _ in time for Christmas.（NMET 2005遼寧卷）A. in order to have received B. in order to receiveC. so as to be received D. so as to be receiving解析 C。so+(

18、adj./adv.)as to do既表目的又可表結(jié)果，在表目的時可以和in order to換用但不可置于句首。so后接形容詞或副詞時只表結(jié)果。此題結(jié)合時態(tài)和語態(tài)對考生進行綜合考查。試比較：例15 My English teachers humor was _ make every student burst into laughter.( NMET 2008江西卷)A. so as to B. such as to C. such that D. so that解析B。從題干動詞make可以看出，選項C和D應(yīng)排除，sosuch that為從屬連詞，后接從句；此處such 為代詞，表這樣的人

19、或物，作表語，后續(xù)不定式表結(jié)果，其前加as to以示強調(diào)。試比較：My English teachers humor was such that makes every student burst into laughter.2as against/for/to/with例16 _ pandas, golden monkeys are in danger of dying out in our country.A. As against B. As for C. As to D. As with解析 D。此題考查as的常見搭配。as against與相對；as for somebodysome

20、thing就而言；as to(依照一定的標(biāo)準(zhǔn)或原則)根據(jù)、依照；as with和一樣。3. as if/though例17 Elize remembers everything exactly as if it _ yesterday.( NMET 2006全國卷)A. was happening B. happens C. has happened D. happened解析D。as if 引導(dǎo)方式狀語從句，同時涉及虛擬語氣的用法。主從句動作同時發(fā)生，對現(xiàn)在假設(shè)，從句用一般過去時；若對過去假設(shè)則用過去完成時。as if后還可接to dodoing等。如：He opens his mouth

21、as if to speak.他張開嘴好像要說話。4.as還有以下常見搭配：(1) Leave the book as it was. 把書原樣放好。(2) Just as exercise is to the body, so is reading to the mind. 正如鍛煉對身體很重要，讀書對大腦也一樣重要。(3) My friend Martin was very sick with a strange fever; as a result, he could neither eat nor sleep. 我的朋友馬丁患了一種奇怪的感冒。結(jié)果，病折騰得他既不能吃又不能睡。(4)

22、Steve, as usual, was the last to arrive.史蒂夫照例來得最晚。(5) Wild flowers such as orchids and primroses are becoming rare.蘭花、報春花等野花越來越稀少。鞏固性練習(xí)：1.
