We should _ our eyes _ being hurt(被傷害) 五、名詞的數(shù) 名詞按其所表示的事物的性質(zhì)可分為可數(shù)名詞和不可數(shù)名詞兩類。可數(shù)名詞有復(fù)數(shù)形式。不可數(shù)名詞一般沒有復(fù)數(shù)形式。可數(shù)名詞的單數(shù)往往要與不定冠詞a/an連用，復(fù)數(shù)則使用其復(fù)數(shù)形式。1. 可數(shù)名詞的數(shù)：可數(shù)名詞復(fù)數(shù)形式的構(gòu)成： 規(guī)則變化：_如：cap cake _如：glass watch _如：shelf knife _如：story baby _如：potato hero 不規(guī)則變化：a. 改變?cè)糇?/p>

16、母，發(fā)音也隨之變化：man(人；男人) woman(女人) postman(郵遞員) fireman(消防員) foot(腳) tooth(牙齒)t goose(鵝) a man teacher(一名男老師) a woman nurse(一名女護(hù)士) b. 單復(fù)數(shù)同形的詞：a sheep(一只羊) a fish（一條魚） a deer（一頭鹿） c. 通常以復(fù)數(shù)形式出現(xiàn)的名詞：scissors(剪刀) trousers(褲子) clothes(衣服) glasses(眼鏡) shorts(短褲)d. 表示“某國(guó)人”的單復(fù)數(shù)：?jiǎn)螖?shù)和復(fù)數(shù)相同， 如：a Japanese a Chinese 變ma

17、n為men, 如：an Englishman a Frenchwoman 詞尾加-s, 如：a German an American 【總結(jié)】中日不變，英法變，其他“s”加后面 e. 其他形式：a childtwo children an oxthree oxen(三頭牛) a mousefour mice（四只老鼠） 不可數(shù)名詞的數(shù):不可數(shù)名詞通常只有單數(shù)形式，前面無(wú)需加不定冠詞a/an。如：water, milk, oil, soil, ink, bread, juice等。但如果需要表示具體的數(shù)量時(shí)，要使用以下短語(yǔ)：a glass of juice a piece of paper a

18、slice of bread 練習(xí)：I根據(jù)句意，用a，an, much或many填空，補(bǔ)全句子。 1. I eat _apple every day.2. Mum, I want to have _ orange. 3. He buys _bananas. 4. In the morning, I drink _ milk. 5. He has _ map.6. Carla has _ different books.7. There is _water on the road.8. He knows _different languages.9. I book _room for my br

19、other. 10. In China, there are_ foreigners(外國(guó)人).六、 There be句型1、構(gòu)成：There be .句型表示的是 “某處(存在)有某人或某物”，其結(jié)構(gòu)為There be(is，are，was, were )+名詞+地點(diǎn)狀語(yǔ)。例如：There are fifty-two students in our class.There is a pencil in my pencil-case.There was an old house by the river five years ago. 1、 各種句式：否定句：There be句型否定句式的構(gòu)成

20、和含有be動(dòng)詞的其它句型一樣，在be后加上“not”。也可用“no”來(lái)表示。即：no + n.（名詞）= not aanany + n.（名詞）。注意：no + n.（可數(shù)名詞單數(shù)）= not aan + n.（可數(shù)名詞單數(shù)）；no + n.（可數(shù)名詞復(fù)數(shù)）= not any + n.（可數(shù)名詞復(fù)數(shù)）；no + n.（不可數(shù)名詞）= not any + n.（不可數(shù)名詞）。例如：There is an orange in her bag.There isnt an orange in her bag. = There is no orange in her bag.There are some

21、 oranges in her bag.There arent any oranges in her bag. = There are no oranges in her bag.There is some juice in the bottle.There isnt any juice in the bottle. = There is no juice in the bottle. 一般疑問句：There be結(jié)構(gòu)的一般疑問句變化只需把be動(dòng)詞移到句首，再在句尾加上問號(hào)即可。例如： There is some money in her handbag. Is there any money

22、 in her handbag? (疑問句和否定句中，some改為any, something改為anything.)There is something new in todays newspaper. Is there anything new in todays newspaper? 3、特殊疑問句：There be句型的特殊疑問句有以下三種形式： 1）對(duì)主語(yǔ)提問：當(dāng)主語(yǔ)是人時(shí)，用 “Whos + 介詞短語(yǔ)?”；當(dāng)主語(yǔ)是物時(shí)，用 “Whats + 介詞短語(yǔ)?”。其中there在口語(yǔ)中常常省略。注意：無(wú)論原句的主語(yǔ)是單數(shù)還是復(fù)數(shù)，對(duì)其提問時(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(lái)決

23、定)。如： There is a bird in the tree. Whats in the tree? There are some bikes over there. Whats over there? There is a little girl in the room. Who is in the room? 對(duì)地點(diǎn)狀語(yǔ)提問：用 “Where is are + 主語(yǔ)?”表示（注意其答語(yǔ)變化）：例如： There is a computer in my office. Where is the computer? Its in my office. There are four chi

24、ldren in the classroom. Where are the four children? They re in the classroom. 對(duì)數(shù)量提問：一般有兩種提問方式：如果主語(yǔ)是可數(shù)名詞，無(wú)論是單數(shù)還是復(fù)數(shù)，都用“How many +可數(shù)名詞復(fù)數(shù) + are there + 介詞短語(yǔ)？”表示如：There are twelve months in a year. How many months are there in a year?There is only one book in my bag. How many books are there in your bag

25、?There is a cat in the box. How many cats are there in the box?如果主語(yǔ)是不可數(shù)名詞，則用“ How much + 不可數(shù)名詞 + is there + 介詞短語(yǔ)？”表示如：There is some money in my purse. How much money is there in your purse? 4、注意事項(xiàng)：1.） There be句型中be動(dòng)詞的形式要和其后的主語(yǔ)在人稱和數(shù)上保持一致。如果句子的主語(yǔ)是單數(shù)的可數(shù)名詞，或是不可數(shù)名詞，be動(dòng)詞用“is”。例如：There is a basketball in t

26、he box.如果句子的主語(yǔ)是復(fù)數(shù)名詞，be動(dòng)詞就用“are”。例如：There are many birds in the tree.如果有兩個(gè)或兩個(gè)以上的名詞作主語(yǔ)，be動(dòng)詞要和最靠近它的那個(gè)主語(yǔ)在數(shù)上保持一致，也就是我們常說(shuō)的 “就近原則”。例如：There is an orange and some bananas in the basket. There are some bananas and an orange in the basket. 2. ）There be句型和havehas的區(qū)別：There be句型表示 “存在有”, havehas表示 “擁有” “所有”,兩者不能

27、同時(shí)使用.例如：桌子上有三本書。 There are three books on the desk.我有三本書。 I have three books.【總結(jié)】There be句型有特點(diǎn)，主語(yǔ)放在be后邊。 主語(yǔ)單三用is，復(fù)數(shù)主語(yǔ)要用are。 變否定，很簡(jiǎn)單，be后要把not添。 變問句也不難，把be提到there前。 肯定句中用some，否定疑問any換。練習(xí)：I.根據(jù)句意，用適當(dāng)?shù)南祫?dòng)詞填空，補(bǔ)全句子。 11. There _ a book and two pens on the desk. 12. There _ many apples in the bag. 13. There _

28、 much water in the glass. 14. There _ an egg on the table.15. There _ many animals in the zoo.
