    101.such as 和for example
    這兩個(gè)短語都可以作“例如”解。for example用來舉例說明某一論點(diǎn)或情況,一般只舉同類人或物中的“一個(gè)”為例,作插入語,可位于句首,句中或句末。例如:
    Ball games, for example, have spread around the world. 球類運(yùn)動(dòng)就已經(jīng)在世界各地傳播開了。
    What would you do if you met a wild animal??a lion, for example? 如果遇上野獸,例如獅子,你該怎么辦?
    such as用來列舉事物時(shí),一般列舉同類人或事物中的幾個(gè)例子。插在被列舉的事物與前面的名詞之間,as后面不可有逗號。例如:
    Some of the rubbish, such as food, paper and iron, rots away over a long period of time.
    有些廢物,如剩飯、廢紙和廢鐵,時(shí)間一久就爛掉了。
    注意:使用這個(gè)短語時(shí),后面列舉的事物的數(shù)量不能等于它前面所提到的總和,一旦相等就要用that is或namely。如不可以說:I have three good friends, such as John, Jack and Tom. 應(yīng)該說:I have three good friends, that is, John, Jack and Tom。我有三個(gè)好朋友,即約翰、杰克和湯姆。
    102.reason 和cause
    The ____ of the big fire was his carelessness.
    A.reason B.cause C.causing D.reasoning
    解答:B。reason強(qiáng)調(diào)一種推理的理由,而cause是指導(dǎo)致某件事情發(fā)生的人或事。
    103.when while 與 as
    1,when表示“當(dāng)……的時(shí)候”。從句中既可用延續(xù)性動(dòng)詞,又可用非延續(xù)性動(dòng)詞,這些動(dòng)詞既可以表示動(dòng)作,又可表示狀態(tài)。從句中的動(dòng)作既可和主句的動(dòng)作同時(shí)發(fā)生,又可在主句的動(dòng)作之前或之后發(fā)生。如:
    When I came into the room, I found him lying there asleep.
    Mary was having dinner when I saw her.
    When you meet a word you don''t know, consult the dictionary.
    She was beautiful when she was a girl.
    如果when從句的主語與主句主語相同,謂語又是be動(dòng)詞,從句主語和be可以省略:當(dāng)when從句主語與主句主語相同時(shí),用when加分詞可以替代狀語從句。如:
    When(you are)in trouble, ask her for help.
    When(I was)sleeping, I never heard a thing.
    2,as
    (1)表示"當(dāng)……時(shí)"、"和……同時(shí)"。常指從句的動(dòng)作未結(jié)束,主句中的動(dòng)作就已發(fā)生。從句中多用表示動(dòng)作的動(dòng)詞,而不用be動(dòng)詞或表示感覺、理解、知道這類動(dòng)詞。
    As he stood there, he saw two men enter the bar.
    She dropped the glass as she stood up.
    As I was walking down the street, an American asked me for directions to the nearest station.
    (2)用于平行的動(dòng)作中,表示"一面……一面……"。常指一個(gè)主語同時(shí)進(jìn)行兩個(gè)動(dòng)作。如:
    He sang as he worked.
    The students took notes as they listened.
    3,While表示"在……的時(shí)候"、"在……期間"。它強(qiáng)調(diào)主句的動(dòng)作與從句的動(dòng)作同時(shí)發(fā)生或主句的動(dòng)作發(fā)生在從句的動(dòng)作過程中。While從句中必須是表示動(dòng)作或狀態(tài)的延續(xù)性動(dòng)詞。如:
    Never get on or off a bus while it is in motion.
    The weather was fine while we were in Beijing.
    She called while I was out.
    104.become,get和turn
    get,turn,become等均可譯為“變得”,但它們在用法上有些區(qū)別。
    (1)get用于日語,通常跟隨比較級。
    It gets coldr。天氣變冷了。
    (2)turn是指在顏色和性質(zhì)等方面變得與原來不同。
    His face truned red。他的臉變紅了。
    (3)become是指身份、職位的變化,作瞬間動(dòng)詞時(shí)指狀態(tài)的變化。
    He becomes a teacher 。他成了一名老師。
    將來“成為”不用“become”而用"be"。
    She will be a teacher。她將成為一名老師。
    105.near 與 beside
    near,by,beside表示“在……附近”的區(qū)別:
    near表示相對的“近”, 實(shí)際距離可能還很遠(yuǎn)。例如:
    Suzhou is near Shanghai.
    There is a post office near our school.
    beside表示“靠近”,實(shí)際距離不可能很遠(yuǎn),例如:
    He was sitting beside her.
