1、第 PAGE15 頁 共 NUMPAGES15 頁六年級(jí)英語語法知識(shí)點(diǎn)講解六年級(jí)英語語法知識(shí)點(diǎn)1、 動(dòng)詞：行為動(dòng)詞、be動(dòng)詞、情態(tài)動(dòng)詞。(1)行為動(dòng)詞原形、+s/es、+ed、+ing，詳細(xì)判斷方法如下：(2)be動(dòng)詞a、Am-was 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。b、肯定和否認(rèn)句I am (not) from London. He /She is(not) a teacher. My hair is(not) long. Hereyes are(not) small.c、 一般疑問句 Am I ? Yes, you ar

2、e. No, you arent. Are you/they? Yes,we/ they are.No,we/ they arent. Is the cat fat? Yes, it is. No, it isnt.is、am、are為一類，一般用于一般如今時(shí)、如今進(jìn)展時(shí)和一般將來時(shí)中。was和were為另一類，一般用于一般過去時(shí)。(3)情態(tài)動(dòng)詞can、must、should、would、may。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)2、 名詞這里強(qiáng)調(diào)兩點(diǎn)：不可數(shù)名詞都默認(rèn)為單數(shù)，所以總是用is或者was。如何加后綴：a.一般情況下，直接加-s，如：book-books, bag-

3、bags, cat-cats, bed-bedsb.以s. x. sh. ch結(jié)尾，加-es，如：bus-buses, box-boxes, brush-brushes, watch-watchesc.以“輔音字母+y”結(jié)尾，變y為i, 再加-es，如：family-families, strawberry-strawberriesd.以“f或fe”結(jié)尾，變f或fe為v, 再加-es，如：knife-knivese.不規(guī)那么名詞復(fù)數(shù)： man-men, woman-women, policeman-policemen, policewoman-policewomen,mouse-mice ch

4、ild-children foot-feet ,.tooth-teeth fish-fish, people-people,Chinese-Chinese, Japanese-Japanese3、 形容詞(包括副詞形容詞表示某一事物或的特征，副詞表示某一動(dòng)作的特征。形容詞和副詞只有兩種形式：原形和+er。未作比擬的情況下就用原形，比擬時(shí)就+er。兩個(gè)重要特征：asas中間一定用原形，有than的時(shí)候一定+er。4、 人稱代詞和物主代詞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(短)名詞性(長)形容詞性(短)名詞性(長)第一人稱Imeweusmymineourours第二人稱you

5、youyouyouyouryoursyouryours第三人稱hehimtheythemhishistheirtheirssheherherhersitititsits人稱代詞：有主格和賓格之分。一般動(dòng)詞前用主格，動(dòng)詞后用賓格。物主代詞：有兩類：形容詞性物主代詞(短的)和名詞性物主代詞(長的)一般看后面有沒有名詞，如有，就用形容詞性物主代詞(短的如無，就用名詞性物主代詞(長的)。5、 數(shù)量詞我們學(xué)過兩類：基數(shù)詞和序數(shù)詞?；鶖?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)。序數(shù)詞的前面一般都加the。6、冠詞有a、an、the。a和an的區(qū)別：an用于元音音素(一般就是元音字母aeiou

6、)前，a用于輔音音素前。六年級(jí)英語語法知識(shí)點(diǎn)be動(dòng)詞(am、is、are、was、were)+not、情態(tài)動(dòng)詞(can、must、should)+ not、助動(dòng)詞(do、does、did) + not如何將一個(gè)肯定的陳述句改為否認(rèn)句：1、看句中有無be動(dòng)詞，如有，直接在be動(dòng)詞后+ not。2、看句中有無情態(tài)動(dòng)詞，如有，直接在情態(tài)動(dòng)詞后+ not。3、如上述二者都沒有，就應(yīng)用助動(dòng)詞+ not。分四個(gè)步驟：(1)肯定陳述句中本來是沒有助動(dòng)詞的，要加上去，位置在主語(某人或某物)后，動(dòng)詞前。(2)確定助動(dòng)詞用do、does還是did，根據(jù)句中動(dòng)詞，動(dòng)詞是原形的助動(dòng)詞就用do，動(dòng)詞是第三人稱單數(shù)的助

7、動(dòng)詞就用does，動(dòng)詞用過去式的助動(dòng)詞就有did(3)在助動(dòng)詞后加not。(4)原句中動(dòng)詞假設(shè)發(fā)生變化就要恢復(fù)成原形。強(qiáng)調(diào)一點(diǎn)，有some的要考慮是否要用any。六年級(jí)英語語法知識(shí)點(diǎn)講解英語語法順口溜：定語從句中的定從中的關(guān)系副詞關(guān)系副詞when/where/why, 從中做狀莫懈怠;時(shí)間用when原因why,地點(diǎn)where經(jīng)常在;定語從句中的關(guān)系副詞有三個(gè)：when, where和why，它們在定語從句中分別作時(shí)間、地點(diǎn)和原因狀語。when指時(shí)間， where指地點(diǎn)，why表原因。例如：I still remember the day when I first came to Beijing

8、.我仍然記得我初次到北京的那天。The factory where his father works is in the west of the city.他父親工作的那個(gè)工廠在城市的西郊。That is the reason why I did the job.那就是我為什么干這個(gè)活的原因。關(guān)系副詞可交換，介詞加上關(guān)系代;關(guān)系副詞可以由介詞加上which來交換。例如：1)This is the house where (in which) I lived two years ago.在這句中，where= in which2) Do you remember the day when (on

9、 which) you joined our club?在這句中，when= on which3) This is the reason why (for which) he came late.在這句中，reason= for which關(guān)系代，關(guān)系代，that與who要除外;挑選介詞要聰明，必看動(dòng)詞和先行;介詞后可用關(guān)系代詞，但只能用which或whom，不能用that 和who。那么，這個(gè)介詞怎么選呢?其一，可以看定語從句中的謂語動(dòng)詞;其二，可以看先行詞。例如：1) The pain from which the poor suffered in this area has attrac

10、ted the attention of the public.本句中用from 加 which, from與定語從句中的謂語動(dòng)詞搭配，suffer from。2) English is a useful tool in which I can municate with foreign friends.本句中用in加which, 和先行詞搭配，先行詞表語言，因此用in。聰明反被聰明誤，只因亂用關(guān)系副;關(guān)系副，關(guān)系副，定缺主賓它不住;它不住，它不住，關(guān)系代詞來玩酷;關(guān)系副詞在定語從句中是做狀語的，where做地點(diǎn)狀語，when做時(shí)間狀語，why做原因狀語，但要特別注意，假如定語從句中所缺的不是

11、狀語，而是主語、賓語或表語，就不要用關(guān)系副詞，而要用關(guān)系代詞。例如：1) I still remember the days _ we spent together in the mountains last summer.先看定語從句中所缺少的句子成分，spent是及物動(dòng)詞，缺賓語，因此不能填when, 而要用關(guān)系代詞which或that。2)This is the house _ his grandfather once lived in.先看定語從句中所缺少的句子成分，lived in, 明顯缺賓語，in是介詞，介詞后應(yīng)該有賓語，所以不能填where, 而要用which或that。3)I

12、s that the reason _ you explained to the teacher for your being late for school?先看定語從句中所缺少的句子成分，explain后應(yīng)該跟雙賓語，缺少一個(gè)賓語，因此不能用why, 而要用which或that。六年級(jí)英語語法知識(shí)點(diǎn)講解英語語法順口溜：定語從句7As/which/So /such thatAs/which在句末，假設(shè)有否認(rèn)as錯(cuò);as和 which都可指代前面一句話，請看例句:1)Alice received an invitation from her boss, which came as a surp

13、rise.愛麗絲受到了她老板的邀請，這使她感到吃驚。2)The weather turned out to be very good, which was more than we could expect.天氣結(jié)果變好了，這是我們沒有意料到的。假設(shè)有否認(rèn)as錯(cuò);3)The result of the experiment was very good, _ we hadnt expected.A. when B. that C. which D. what【簡析】答案是C。由于非限定性定語從句是否認(rèn)構(gòu)造，只能用which引導(dǎo)，不能用as來替代which。句首只能用as,還有認(rèn)知猜測詞;置于句首

14、時(shí)，非限定性定語從句只能用as引導(dǎo)。例如：As is known to everybody, the moon travels round the earth once every month.眾所周知，月亮每月繞地球一周。與表示認(rèn)知猜測的詞，如know, expect, see, report, 連用時(shí)，要用as。1)As we know, smoking is harmful to ones health.我們知道，吸煙對安康有害。2)As is expected, his daughter entered a key university.正如人們所期望的那樣，他的女兒考入了一所重點(diǎn)大學(xué)

15、。固定構(gòu)造用as, the same /such/so/as;1) 在the same as.構(gòu)造中。意思是 “像一樣的”。 例如：Chongqing is not the same city as we have seen in other places.重慶和我們在其它地方看過的城市不一樣。注意區(qū)分: the same .that.,請看例句：This is the same pen that I lost. 這正是我所丟的鋼筆。(同一)This is the same pen as I lost. 這支鋼筆和我丟的那支一樣。(相似，不是一個(gè))2)在as.as構(gòu)造中，意思是“像那樣的”。例

16、如：No period in history has had as many important changes _ have taken place in the past century. 沒有哪個(gè)歷史階段像過去的一個(gè)世紀(jì)這樣有如此多的重大變化。3)在suchas構(gòu)造中, 意思是“像那樣的”。例如：Mathilde had to work hard day and night and bought such a diamond necklace as she had lost to pay back to Jeanne.馬帝爾德不得不日日夜夜地干活，來買一個(gè)像被她丟掉的那樣的鉆石項(xiàng)鏈還給讓

17、。So /such that賓不離，so/suchas賓要棄;在so/suchthat構(gòu)造中，that后引導(dǎo)的不是定語從句，而是狀語從句，從句中必須有賓語;在so/suchas構(gòu)造中， as后引導(dǎo)的是定語從句，從句中不帶賓語。例如：1)He studies in such a good school that all other students in his village admire him.他在那樣好的一所學(xué)校學(xué)習(xí)，以致于村子里其他的學(xué)生都很羨慕他。解析：that后是狀語從句，狀語從句中有賓語him。2)He studies in such a good school as all o

18、ther students in his village admire.他在那樣好的一所學(xué)校學(xué)習(xí)，村里的其它學(xué)生都很羨慕那所學(xué)校。解析：as后是定語從句,as代替先行詞school,在定語從句中做admire的賓語。六年級(jí)英語語法知識(shí)點(diǎn)動(dòng)詞過去式、如今分詞的不規(guī)那么變化：be 是-was, were-beingbegin 開場-began-beginningbuild 建筑-built-buildingbuy 買-bought-buyingcan 能-could-無e 來-came-ingcopy 拷貝-copied-copyingdo 做-did-doingdraw 畫-drew-drawingdrink 喝-drank-drinkingdrive 駕車-drove-drivingeat 吃-ate-eatingfeel 感覺-felt-feelingfind 找尋-found-findingfly飛-flew-flyingforget 忘記-forgot-forgettingget 得到-got-gettinggive 給予-gave-givinggo 去-went-goinggrow 成長-grew-growinghave 有
