小學(xué)英語語法知識(shí)點(diǎn)-精講+精練

1、精選優(yōu)質(zhì)文檔-傾情為你奉上小學(xué)英語語法知識(shí)點(diǎn)匯總 精講+精練一、 名 詞表示某一事物，有具體的和抽象的之分。分為可數(shù)名詞和不可數(shù)名詞。強(qiáng)調(diào)：不可數(shù)名詞都默認(rèn)為單數(shù)，所以總是用is或者was；最好不要根據(jù)some、any、a lot of等詞去作判斷，以免受誤導(dǎo)。 1、可數(shù)名詞如何變“復(fù)數(shù)形式”：a一般情況下，直接加-s，如：book-books, bag-bags, cat-cats, bed-beds ；讀音：清輔音后讀 s， 濁輔音和元音后讀z。b以s. x. sh. ch結(jié)尾，加-es，如：bus-buses, box-boxes, brush-brushes, watch-watche

2、s ；讀音：iz。c以“輔音字母+y”結(jié)尾，變y為i, 再加-es，如：family-families, strawberry-strawberries ；讀音：z。d以“f或fe”結(jié)尾，變f或fe為v, 再加-es，如：knife-knives ，thief-thieves；讀音：z。e以“o”結(jié)尾的詞，分兩種情況1）有生命的+es 讀音：z 如：mango-mangoes tomato-tomatoes hero-heroes2) 無生命的+s 讀音：z 如：photo-photos radio-radiosf. 不規(guī)則名詞復(fù)數(shù)： man-men, woman-women, policem

3、an-policemen, policewoman-policewomen, snowman-snowmen, mouse-mice, child-children, foot-feet, tooth-teeth, fish-fish, people-people, Chinese-Chinese, Japanese-Japanese 2、不可數(shù)名詞沒有復(fù)數(shù)。如果要計(jì)算不可數(shù)名詞所表達(dá)的數(shù)量，就得在數(shù)詞和不可數(shù)名詞之間加上“量詞+of”。例如：a glass of water, a piece of paper, a bottle of juice判斷步驟： 如是am、is或was原形讀句子讀

4、該單詞認(rèn)識(shí)該單詞理解意思看be動(dòng)詞 如是are或were加s或es練一練1、寫出下列各詞的復(fù)數(shù)。 I _ him _ this _ her_ watch_ mango_child _photo _ diary _ day_ foot_ dress _ tooth_ sheep _ box_ strawberry _ thief _ engineer_ peach_sandwich _ man_ woman_ leaf_ people_2、用所給名詞的正確形式填空。（1）Are there two ( box ) on the table?（2）I can see some ( people )

5、 in the cinema.（3）How many ( day ) are there in a week?（4）Herere five ( bottle ) of ( juice ) for you.（5）This ( violin ) is hers. Those ( grape ) are over there.二、冠 詞冠詞是一種虛詞，不能獨(dú)立使用，通常放在名詞的前面，分為“不定冠詞”和“定冠詞”兩種。1、不定冠詞：a、an。用在單數(shù)名詞前，表示“一個(gè)，一件”。an用在以元音“音素”開頭的單詞前。如： an e-mail, an orange, an old man, an Engl

6、ish watch, an hour2、定冠詞：the。用在單數(shù)或者復(fù)數(shù)名詞前。the沒有具體意思，有時(shí)翻譯為這、那。它的基本用法： （1）用來表示特指某（些）人或某（些）事物。如：The map on the wall is new. （2）表示說話者雙方都知道的人或事物。如：Look at the picture, please. （3）表示再次提到前面談過的人或事物。如：This is a stamp. The stamp is beautiful. （4）用在表示世界上獨(dú)一無二的事物前。如：the sun太陽 the moon月亮 the earth地球 （5）用在由普通名詞構(gòu)成的專有

7、名詞前。如：the Great Wall長城 （6）用在江河、湖海等專有名詞前。如：the Changjiang River長江 （7）此外，序數(shù)詞、形容詞最高級(jí)、樂器名稱等詞前面和一些習(xí)慣用語中一般都用定冠詞the。如：the first day, the best boy, play the piano, in the same class確定用a、an還是the時(shí)可根據(jù)漢語意思。練一練1、用a或an填空。_ “U”_ ice-cream _ goalkeeper_ teapot _apple_office _English book _umbrella _unit _hour 2、根據(jù)需

8、要，填寫冠詞a，an或the。（1）Who is_girl behind_tree?（2）_old man has two children,_ son and_daughter.（3）This is_ orange._ orange is Lucys.（4）He likes playing_guitar. We have_same hobby.（5）We all had_good time last Sunday.（6）She wants to be_doctor.三 數(shù) 詞我們學(xué)過兩類：基數(shù)詞和序數(shù)詞。基數(shù)用于表示數(shù)量多少，而基數(shù)詞用于表示次序，常在日期中出現(xiàn)。區(qū)別：基數(shù)詞前面沒有“the

9、”；序數(shù)詞前一定要有“the”。1、超過二十以上的兩位數(shù)需要在個(gè)位和十位之間加上“-”。如：21 twenty-one2、三位數(shù)以上的則需要在百位數(shù)后再加上and。如：101 a/one hundred and one3、用基數(shù)詞來修飾可數(shù)名詞時(shí)，一定別忘了它的復(fù)數(shù)形式。如：十八個(gè)男孩 eighteen boys4、用基數(shù)詞修飾不可數(shù)名詞時(shí)，如是復(fù)數(shù)，變它的量詞為復(fù)數(shù)。如：兩碗米飯 two bowls of rice5、序數(shù)詞一般加“th”，特殊的有：first, second, third, fifth, eighth, ninth, twelfth以及二十及二十以外的整十：twentiet

10、h, thirtieth, fortieth “第幾十幾”：前面整十不變，后面“幾”改為序數(shù)詞。如：88 eighty-eighth練一練1、請翻譯下列短語。 （1）60名學(xué)生 （2）15本英語書 （3）九杯涼水 （4）4個(gè)孩子 （5）12月31 （6）6月2日 （7）第九周 （8）40年前 （9）11+7 （10）上學(xué)第一天 2、把下列基數(shù)詞改成序數(shù)詞。one- two- three- nine- fourteen- twenty- thirty-five-eighty-one四、代 詞代詞有兩種：人稱代詞和物主代詞。1、人稱代詞分為：第一、第二、第三人稱，且有單復(fù)數(shù)之分。2、人稱代詞的主格

11、在句中做主語，一般用在動(dòng)詞前（疑問句除外）；賓格在句中做賓語，多 用于動(dòng)詞、介詞后。3、形容詞性物主代詞起形容詞的作用，后面一定要跟名詞，表示該名詞是屬于誰的。4、名詞性物主代詞=形容詞性物主代詞+名詞。如： This is my bag. = This is mine. That is her ruler. = That is hers.一般看后面有沒有名詞，如有，就用形容詞性物主代詞；如無，就用名詞性物主代詞。 請牢記下表：單數(shù)復(fù)數(shù)人稱 代詞主格Iyouhesheitweyouthey賓格meyouhimheritusyouthem物主 代詞形容詞性myyourhisheritsouryo

12、urtheir名詞性mineyourshishersitsoursyourstheirs練一練1、按要求寫出相應(yīng)人稱代詞。I（賓格）_ she（形容詞性物主代詞）_ we（名詞性物主代詞）_ he（復(fù)數(shù)）_ us（單數(shù)）_ theirs（主格）_ its（賓格）_ 2、想一想，把下表補(bǔ)充完整。人稱代詞物主代詞單數(shù)復(fù)數(shù)單數(shù)復(fù)數(shù)主格賓格主格賓格形容詞性名詞性形容詞性名詞性第一人稱meusour第二人稱youyou第三人稱hethemhistheirheritits3、用所給詞的適當(dāng)形式填空。1）That is not _ kite. That kite is very small, but _ i

13、s very big. ( I )2）The dress is _. Give it to _. ( she ) 3）Is this _ watch? ( you ) No, its not _ . ( I ) 4）_ is my brother. _ name is Jack. Look! Those stamps are _. ( he ) 5）_ dresses are red.

15、not a cat, _ is a tiger! ( it )13）_ sister is ill. Please go and see _. ( she ) 14）The girl behind _ is our friend. ( she )五、形容詞、副詞1、形容詞表示某一事物或人的特征，副詞表示某一動(dòng)作的特征。形容詞和副詞有三種形式：原形、比較級(jí)、最高級(jí)。比較級(jí)：+er 最高級(jí)：the +est兩個(gè)重要特征：asas中間一定用原形，than的前面一定要+er。2、形容詞、副詞比較級(jí)的規(guī)則變化如下：（1）一般直接+er。如：tall - taller, fast - faster 單音節(jié)

16、詞如果以-e結(jié)尾，只加-r。如：late - later（2）重讀閉音節(jié)詞如末尾只有一個(gè)輔音字母，須雙寫這個(gè)字母，再加-er。如：big - bigger, fat - fatter（3）以輔音字母加-y結(jié)尾的詞，變y為i，再加-er。如：heavy - heavier, early - earlier（4）雙音節(jié)和多音節(jié)詞的比較級(jí)應(yīng)在原級(jí)前加more構(gòu)成。如：beautiful - more beautiful, careful - more careful, quietly - more quietly, interesting - more interesting（5）有些不規(guī)則變化的，

17、須逐一加以記憶。如：good/well better, bad/ill worse, many/much more, far farther/further, old older/elder練一練1、寫出下列形容詞、副詞的比較級(jí)。big good long tall old short thin heavy young fat light strong high far low early late well fast slow 2、用括號(hào)內(nèi)所給單詞的適當(dāng)形式填空。1) I can swim as_ ( fast ) as the fish, I think.2) Look!

19、e of the boys in my class.8) Im very_ ( thin ), but shes_ ( thin ) than me.9) It gets_and_ ( warm ) when spring comes here.六、介 詞1、一種虛詞。不能單獨(dú)作句子成分，它只有跟它后面的賓語一起構(gòu)成介詞短語，才能在句子中起作用。有：in, on, under, with, behind, about, near, before, after, for, to, up, down, from, in front of, out of, fromto, at the back o

20、f2、表示時(shí)間的介詞有：at, on, in。（1）at表示“在某一個(gè)具體的時(shí)間點(diǎn)上”，或用在固定詞組中。如：at ten oclock, at 9:30 a.m., at night, at the weekend（2）on表示“在某日或某日的時(shí)間段”。如：on Friday, on the first of October, on Monday morning（3）in表示“在某一段時(shí)間（月份、季節(jié)）里”。如：in the afternoon, in September, in summer, in 20053、in一詞還有其他的固定搭配，如：in blue（穿著藍(lán)色的衣服），in Eng

24、me on my English? 9) I usually take photos in Sunday morning. 10) What did you do on the Spring Festival? 七、動(dòng) 詞這里所說的動(dòng)詞是指各種動(dòng)詞總稱，其中包括be動(dòng)詞、情態(tài)動(dòng)詞、助動(dòng)詞、行為動(dòng)詞（就是我們平時(shí)總說的那種動(dòng)詞）。 動(dòng)詞、名詞和形容詞不太容易區(qū)分，如不能一眼看出，可用如下方法： 先用“一（量詞）”（如：一個(gè)、一張等）和這個(gè)詞連起來說，如說得通，一般認(rèn)為是名詞；說不通再用“很”去判斷，就是把“很”和為個(gè)詞連起來說，說得通一般就是形容詞；都說不通就是動(dòng)詞。（目前我們學(xué)過的，以后可能不

25、同）（另外一些很明顯的，如人稱代詞、數(shù)詞、情態(tài)動(dòng)詞等一下就可以知道） 1、be動(dòng)詞（ am, is, are, was, were ）1）amwas, is was, are-were 口訣：我用am, 你用are, is用在他她它，所有復(fù)數(shù)全用are。2）肯定和否定句 I am (not) from London.

29、ad on the plate. 25）You, he and I _ from China.26）There _ a boy, two girls, three men and ten women in the park. 2、助動(dòng)詞（ do, does, did ）do, does用于一般現(xiàn)在時(shí)，其過去式did用于一般過去時(shí)。它們通常用在疑問句和否定句中。它們的否定形式：do not = dont, does not = doesnt, did not = didnt。注意：在一般現(xiàn)在時(shí)中，does用于第三人稱單數(shù)，其余一律用助動(dòng)詞do；助動(dòng)詞do, does, did后面一定要用動(dòng)詞原形

A B C3、情態(tài)動(dòng)詞情態(tài)動(dòng)詞也是一類特殊的動(dòng)詞，平時(shí)我們不把它說成是動(dòng)詞。情態(tài)動(dòng)詞可以和行為動(dòng)詞同時(shí)出現(xiàn)在同一個(gè)句子中。我們現(xiàn)在學(xué)過的情態(tài)動(dòng)詞有：can、could、shall、should、will、would、m

33、ay、might 、must。注意：情態(tài)動(dòng)詞后動(dòng)詞總是用原形。（不受其他任何條件影響）其否定形式：can not = cant, must not = mustnt, 注意：may not和shall not（無縮寫形式）練一練選擇填空。( ) 1) The sign on the wall means you_stay away from the building.

35、sweep、live等。行為動(dòng)詞我們已學(xué)過它們的四種形式：原形、第三人稱單數(shù)+s/es、現(xiàn)在分詞（也叫動(dòng)名詞）+ing、過去式+ed。 （1）動(dòng)詞第三人稱單數(shù)變化規(guī)則：A、一般直接加“s”，如：play plays, visit visits, speak speaks ；B、以“s”，“x”，“sh”，“ch”結(jié)尾時(shí)，加“es”，如：catch catches, watch watches ；C、以“輔音字母+y”結(jié)尾時(shí)，變“y”為“i”再加“es”，如：carry carries, study studies 。（2）現(xiàn)在分詞（動(dòng)名詞）構(gòu)成規(guī)則：A、一般直接加“ing”，如：go goin
