初中英語There be句型基本用法注意點

字號:

There be句型的基本用法是表示“某地(或某時)存在有某人(或某物),而并非某地(某人、某物或某時)擁有什么東西”,其形式為“There be+代詞或名詞(短語)+地點/時間狀語”。(其實質(zhì)句式為倒裝句)這里there是引導(dǎo)詞,沒有詞義,be是謂語動詞,代詞或名詞(短語)是主語。be要與主語保持人稱和數(shù)的一致。否定句是在be后加not;一般疑問句是將be放在句首;反意疑問句中的簡短問句是由“be(或其否定式)+there”構(gòu)成。例如:
     1. There is a desk and two chairs in the room. (緊挨著be動詞的主語是a desk,是單數(shù),故be的形式要用is)
     2. There aren't two chairs and a desk in the room. (否定句)
     3. Is there anything wrong with your ears? (Yes,there is/No,there isn't.)
     4. There wasn't a meeting yesterday, was there?(反意疑問句)
     除此之外,還有一個重要句式“有某人在做某事”,要用“There be+sb.+doing sth.+地點/時間狀語”。例如:
     There are several children swimming in the river. 河里有幾個孩子在游泳。
     不難看出,各種時態(tài)的變化是通過be動詞的變化來體現(xiàn)的。我們在使用過程中,首要的問題是弄清楚There be與have所表示的意義。There be句型表示“存在”關(guān)系,have表示“所屬”關(guān)系,兩者不能混合在一個句子中。 例如:我們要說“明天有一個班會?!?BR>     (1) There will have a class meeting tomorrow. (×)
     (2) There is going to/will be a class meeting tomorrow. (√)
     有時候既表示“存在”又表示“所屬”時,兩種都可以用。
     例如:Class Three have a map of China on the wall. (地圖為三班學(xué)生所有。)
     There is a map of China on the wall in Class Three. (地圖存在于三班。)
     由此看來,There will have是錯誤的搭配方式。
     使用There be句型時除了掌握基礎(chǔ)知識外,還應(yīng)注意以下問題:
     1. There be句型的考查更多的是將be動詞與主語結(jié)合在一起進(jìn)行的,即主謂的一致性。
     例如:(1)There is _____ on the floor.
     (2)There are _____ on the floor.
     選項:A. cat B. water C. boxes D. football
     解析:(1)由is可知主語應(yīng)是可數(shù)名詞單數(shù)或不可數(shù)名詞,而A、D項中都缺少冠詞a,故選B,同理可知(2)應(yīng)選C。 2. 如果作主語的是一個短語,則常??疾槎陶Z中的修飾語。可數(shù)名詞的復(fù)數(shù)形式前可以用any, some, few, a few, many或用數(shù)詞+hundred/thousand/million, hundreds/thousands/millions of, no等修飾;不可數(shù)名詞可以受any, some, no, little, a little,much等詞的修飾。例如:
    (1)There were_____ students in our school.
     A. hundreds B. eight hundred C. eight hundreds of
    (2)There is _____water. You needn't get some more.
     A. few B. little C. much
     解析:(1)由數(shù)詞與名詞的搭配關(guān)系可知選B,(2)由water可知排除A項,再由后一句意思便知選C。
     3. 注意不定代詞的用法。
     (1) 不定代詞在句中作主語,謂語動詞要用單數(shù)形式。例如:There is nothing in the fridge. (2) 不定代詞受形容詞修飾時要放在形容詞前面。例如:There is something interesting in today's newspaper.
     4. There be句型的反意疑問句,要注意陳述部分的形式。 如果陳述部分含有l(wèi)ittle,few,no,nobody,none等否定詞時,后面的簡短問句中要用肯定形式。例如:There is nobody in the room,is there?
     但有的含有否定意義的形容詞修飾不定代詞時則仍看做肯定句式。例如:There is something unusual in the room,isn't there?
     5. 要注意句子前后意思的一致性。
     有的句子單獨看其意義時,可能不止一個選項適合于它,但如果聯(lián)系上下句的意思則只能有一個恰當(dāng)?shù)倪x項。
    例如:
    (1)There is _____ food. You needn't buy any.
     A. any B. some C. no
    (2) There is _____ food. You have to buy some.
     A. any B. some C. no
     從這兩題中的第一個句子來看均可選用some和no,但與后面的句意結(jié)合看,答案則是的:(1)B;(2)C。
     6. There be句型還有就近一致原則:即be動詞的數(shù)應(yīng)與離它最近的一個主語保持一致。 例如:用be動詞的適當(dāng)形式填空
     (1) There ___ an apple and three oranges on the table.
     (2)___ there three oranges and an apple on the table?
     解析:(1)因為該句中an apple才是與be動詞接近的主語,而并非an apple and three oranges是句子的主語,故而(1)的答案應(yīng)為is。
     (2) 因為該句中three oranges才是與be動詞接近的主語,而并非three oranges and an apple是句子的主語,故而(2)的答案應(yīng)為Are。
     There be句型命題趨向有兩個方面:一是進(jìn)一步加強(qiáng)對知識的理解與運(yùn)用方面的考查。例如be動詞與主語的一致性、名詞或代詞的修飾語、搭配關(guān)系、含否定詞的反意疑問句等。二是有可能出現(xiàn)“有某人在做某事”這一句型,即“There be+sb.+doing sth.+地點/時間狀語”。另外,還得提醒一下同學(xué)們,如果要表達(dá)諸如“這里/那里(挺漂亮……)等”這樣的修飾句型,應(yīng)用“It’s… here/there.”而不是“Here/there is…”。中考原題
