七年級(jí)語法——there-be句型講解

1、精選優(yōu)質(zhì)文檔-傾情為你奉上there be 句型講解There be 句型1. 定義：There be句型表示某處存在某物或某人。2. 結(jié)構(gòu)：There is+第三人稱單數(shù)可數(shù)/不可數(shù)名詞+地點(diǎn)狀語例：There is a ruler on the desk. 書桌上有一把尺。There is some water in the bottle. 瓶子里有一些水。There are+復(fù)數(shù)名詞+地點(diǎn)狀語例：There are four apples on the tree.樹上有四個(gè)蘋果。There are many flowers in the park.公園里有許多花。   

2、;       there是引導(dǎo)詞，在句中不充當(dāng)任何成分，翻譯時(shí)也不必譯出。注意：句子的主語是某人或某物，謂語動(dòng)詞be要與主語（某人或某物）的數(shù)保持一致。當(dāng)主語是兩個(gè)或兩個(gè)以上的名詞時(shí)，謂語動(dòng)詞要與跟它最近的那個(gè)名詞一致。eg.  There is a bird in the tree.   樹上有一只鳥。    There is a teacher and many students in our classroom.  我們教室里有一位老師和許多學(xué)生。 

3、;   There are two boys and a girl under the tree. 樹下有兩個(gè)男孩，一個(gè)女孩。3.  There be句型與have的區(qū)別：(1) There be 句型和have都表示“有”的含義。區(qū)別如下：There be表示“某處存在某物或某人”；have表示“某人擁有某物/某人”，它表示所有、擁有關(guān)系。     He has two sons.  他有兩個(gè)兒子。 There are two men in the office.    辦

4、公室里有兩個(gè)男人。(2)當(dāng)have表示“包括”、“存在”的含義時(shí)，There be 句型與其可互換。eg.   A week has seven days. =There are seven days in a week.  一個(gè)星期有七天。4. There be 句型轉(zhuǎn)換變臉一：否定句 There be句型的否定式的構(gòu)成和含有be動(dòng)詞的其它句型一樣，在be后加上not或no即可。注意not和no的不同：not是副詞，no為形容詞，not a/an/any + n. 相當(dāng)于no+ n.。There be否定句型中的not any與no可以互換。not any強(qiáng)調(diào)一

5、個(gè)都沒有。1. There are not any books in the bag.=There are no books in the bag.2. There are no students in the classroom.=There are not any students in the classroom.3. There is not any milk in the bottle.=There is no milk in the bottle.There are some pictures on the wall. There aren't any pictures o

6、n the wall. =There are no pictures on the wall. There is a bike behind the tree. There isn't a bike behind the tree. =There is no bike behind the tree. 變臉二：一般疑問句 There be句型的一般疑問句變化是把be動(dòng)詞調(diào)整到句首，再在句尾加上問號(hào)即可，此為"調(diào)整法"。但同時(shí)要注意：當(dāng)肯定句中有some時(shí)，要將其改為any（否定變化也一樣）。看看下面兩句是如何"改頭換面"的吧： There is

7、some water on Mars. Is there any water on Mars? There are some fish in the water. Are there any fish in the water? 肯定回答為：Yes, there is/are. 否定回答為: No, there isnt/arent. 變臉三：特殊疑問句 There be句型的特殊疑問句形式有以下三種變化： 對(duì)主語提問：當(dāng)主語是人時(shí)，用"Who's+介詞短語?"；當(dāng)主語是物時(shí)，用"What's + 介詞短語?"。注意：無論原句的

8、主語是單數(shù)還是復(fù)數(shù)，對(duì)之提問時(shí)一般都用be的單數(shù)形式(回答時(shí)卻要根據(jù)實(shí)際情況來決定)。如There are many things over there. What's over there? There is a little girl in the room.Who is in the room? 對(duì)地點(diǎn)狀語提問：提問地點(diǎn)當(dāng)然用"Where is / are+主語?"啦！例如： There is a computer on the desk. Where is the computer? There are four children on the playgr

9、ound. Where are the four children? 對(duì)數(shù)量提問：一般有兩種句型結(jié)構(gòu)： How many+復(fù)數(shù)名詞+are there+介詞短語？ How much+不可數(shù)名詞+is there+介詞短語？5. There be 的一般將來時(shí) 結(jié)構(gòu)： There + will +be+名詞+其他。There +is/are going to+be +名詞+其他。There will be a book show in the playground tomorrow.=There is going to be a book show in the playground tomor

10、row.There won't be many books in the room next time.= There are not going to be many books in the room next time.have，has一1表示：某人或某物“擁有”什么東西，強(qiáng)調(diào)“所屬關(guān)系”，而且某人某物作為句子的主語。2have用在人稱I，we，you，they和復(fù)數(shù)的人或物后面。has用在人稱he, she, it和單數(shù)和人或物后面。I have a daughter. He has a lucky dog.二、have的搭配1“have 表示一日三餐的名詞”，意為“用餐”。如

11、：have breakfast吃早餐，have lunch吃午飯，have supper吃晚飯。2“have 表示食品、飲料等名詞”，意為“吃；喝”。如：have (some) bread吃面包，have eggs (for breakfast) (早餐)吃雞蛋，have (a cup of) tea 喝(一杯)茶。3“have 表示動(dòng)作的名詞”，沒有固定的意思，常與表示動(dòng)作的名詞同義。如：have a rest 休息一下 have a swim 游泳 have a drink (of)喝一點(diǎn)()have a look (at )(朝)看一眼4“have 表示某種活動(dòng)的名詞”，意為“進(jìn)行，舉行

12、”。如：have a class (學(xué)生) 上課 have a birthday party 舉行生日聚會(huì)三、have/ has的用法：1) 謂語動(dòng)詞have表示“有”，有兩種形式：have和has，前者用于第一人稱(I, we)，第二人稱(you)和第三人稱復(fù)數(shù)(they)，后者用于第三人稱單數(shù)(he, she, it)或單數(shù)名詞。  I have an apple and he has two bananas. You have a new English teacher.   It has two big eyes. Julie and Jack have a nic

13、e car. 2) have/has句型與there be句型的比較：兩者都表示“有”，但用法不同。前者表示所屬關(guān)系，即表示“某人或某物有什么”，而后者表示存在，表示“某地有什么”。   She has a lot of pretty skirts.    There are a lot of pretty skirts in the shop.3)  have/ has的否定句，一般要加助動(dòng)詞do/ does，再加not構(gòu)成，即do not have (dont have)/ does not have (doesnt have) She does not have a sister. We dont have any classes on Saturday. 我們星期六沒有課。 Ann and I dont have a big room. 我和安沒有一個(gè)大房間。4) &
