        關(guān)鍵詞:肯定句中作否定句

        王 珺

        There be結(jié)構(gòu)的基本句型是“There+be+主語(yǔ)+其他(狀語(yǔ)、定語(yǔ)等)”。它表示“某時(shí)某處有某人或某物”。there是引導(dǎo)詞,無(wú)詞義,應(yīng)弱讀。There be位居該句型的句首。如:

        There is a small village at the foot of the mountain.

        要掌握There be句型需熟知以下幾條:

        1. There be結(jié)構(gòu)中be動(dòng)詞數(shù)的確定。

        be動(dòng)詞的數(shù)由它后面的主語(yǔ)來(lái)定。若主語(yǔ)是可數(shù)名詞單數(shù)或不可數(shù)名詞,則be動(dòng)詞應(yīng)是單數(shù)is或was;若主語(yǔ)是可數(shù)名詞復(fù)數(shù),則be動(dòng)詞應(yīng)是復(fù)數(shù)are或were。如:

        There is a new dictionary in her hand.

        There are a lot of people at the meeting.

        如果有兩個(gè)或更多主語(yǔ),be動(dòng)詞一般與離得最近的主語(yǔ)保持一致,即“就近一致”。如:

        There is a girl, two boys and some teachers on the playground.

        There are two boys, a girl and some teachers on the playground.

        2. There be結(jié)構(gòu)中be的時(shí)態(tài)變化。

        ①一般現(xiàn)在時(shí):be的形式是is/are。如:

        There is much milk here.

        Are there any boys here?

        ②一般過(guò)去時(shí):be的形式是was/were。如:

        Were there any students in the reading room yesterday?

        There were some sheep on the road twenty minutes ago.

        ③一般將來(lái)時(shí):be的形式是will be,也可以是be going to be。如:

        There will be a meeting next week.

        There is going to be a meeting next week.

        3. There be結(jié)構(gòu)的句型轉(zhuǎn)化。

        ⑴肯定句變?yōu)榉穸ň?/p>

        ①There be結(jié)構(gòu)的肯定句變否定句時(shí),需在be后加not。is not可縮寫(xiě)成isnt, are not可縮寫(xiě)成arent。

        ②這一結(jié)構(gòu)的肯定句中有some時(shí),需把some改為any。如:

        a. There is a girl playing in the garden.→There isnt a girl playing in the garden.

        b. There are some books on the desk.→There arent any books on the desk.

        ③There be結(jié)構(gòu)中作主語(yǔ)的名詞前有a(an)或some時(shí),變否定句,可以把not a(an)或not any改為no。即:not a(an)=no, not any=no。

        如上面a、b兩句的否定句可以分別是:

        There is no girl playing in the garden.

        There are no books on the desk.

        ⑵否定句變?yōu)榭隙ň?/p>

        ①There be結(jié)構(gòu)的否定句變肯定句時(shí)把be后的not去掉,將any改為some。如:

        There isnt any ink in the bottle.→There is some ink in the bottle.

        ②如果否定句中be后是no+名詞,改為肯定句時(shí),根據(jù)主語(yǔ)的單、復(fù)數(shù)把no直接改為a(an)或some。主語(yǔ)為單數(shù)時(shí)改為a(an),主語(yǔ)為復(fù)數(shù)或不可數(shù)名詞時(shí)改為some。如:

        a. There is no exercise book with her.→There is an exercise book with her.

        b. There is no water here and there.→There is some water here and there.

        c. There are no lamps in the room.→There are some lamps in the room.

        ⑶肯定句變?yōu)橐话阋蓡?wèn)句

        There be結(jié)構(gòu)的肯定句變?yōu)橐话阋蓡?wèn)句時(shí),需把be提到there前,be的第一個(gè)字母大寫(xiě),句末用問(wèn)號(hào)。如果主語(yǔ)前有some,需把some改為any。如:

        There are some apples in the basket.→Are there any apples in the basket?

        其答語(yǔ)為:Yes, there are./No, there arent (any).

        ⑷There be結(jié)構(gòu)的特殊疑問(wèn)句

        There be結(jié)構(gòu)的基本句型是“There+be+主語(yǔ)+介詞短語(yǔ)”。

        ①對(duì)句型中主語(yǔ)部分劃線(xiàn)提問(wèn),其特殊疑問(wèn)句應(yīng)為:Whats+介詞短語(yǔ)?如:

        a. There is some water in the cup.→Whats in the cup?

        b. There are 20 people in the room.→Whats in the room?

        ②<1>There be結(jié)構(gòu)基本句型中作主語(yǔ)的名詞如果是可數(shù)名詞,對(duì)名詞前的數(shù)詞(one,three…)或相當(dāng)于數(shù)詞的詞(some,a few,many…)提問(wèn),其特殊疑問(wèn)句形式為“How many+可數(shù)名詞復(fù)數(shù)+are there+介詞短語(yǔ)?”如:

        a. There is a radio on the table.→How many radios are there on the table?

        b. There are a few students in the classroom.→How many students are there in the classroom?

        <2>如果there be句型中作主語(yǔ)的為不可數(shù)名詞,對(duì)不可數(shù)名詞前的表示數(shù)量的詞some, a little或短語(yǔ)a cup of, three bottles of…提問(wèn),其特殊疑問(wèn)句形式為“How much+不可數(shù)名詞+is there+介詞短語(yǔ)?”。如:

        There is a little milk in the bottle.→How much milk is there in the bottle?

        4. There be結(jié)構(gòu),謂語(yǔ)動(dòng)詞除be外,還可用某些含有“存在”意義的不及物動(dòng)詞或詞組,如live, stand, lie, come, enter等。如:

        There stands a bridge across the river.

        Many years ago there lived an old man.

        Then there came a knock at the door.

        5. There be結(jié)構(gòu)不能與have(有)混用。

        ①There be表示“存在”,have表示“擁有”。所以不能把There be中的be改為have。如:

        There are five windows in the room. (√)

        There have five windows in the room. (×)

        ②當(dāng)have表示事物特征時(shí),可用“主語(yǔ)+have”結(jié)構(gòu)替換There be結(jié)構(gòu)。如:

        a. There are five windows in the room.→This room has five windows.

        b. There is a book in my hand.→I have a book in my hand.
