英語的語法知識
英語之中，你對于它的動詞語法了解多少?下面是學(xué)習(xí)啦小編給大家整理的英語語法，供大家參閱!
英語語法：系動詞
系動詞亦稱聯(lián)系動詞(Link Verb)，作為系動詞，它本身有詞義，但不能單獨(dú)用作謂語，后邊必須跟表語(亦稱補(bǔ)語)，構(gòu)成系表結(jié)構(gòu)說明主語的狀況、性質(zhì)、特征等情況。
說明：
有些系動詞又是實(shí)義動詞，該動詞表達(dá)實(shí)義時，有詞義，可單獨(dú)作謂語，例如：
He fell ill yesterday.
他昨天病了。(fell是系動詞，后跟補(bǔ)足語，說明主語情況。)
He fell off the ladder.
他從梯子上摔下來。fell是實(shí)義動詞，單獨(dú)作謂語。
1)狀態(tài)系動詞
用來表示主語狀態(tài)，只有be一詞，例如：
He is a teacher. 他是一名教師。(is與補(bǔ)足語一起說明主語的身份。)
2)持續(xù)系動詞
用來表示主語繼續(xù)或保持一種狀況或態(tài)度，主要有keep, rest, remain, stay, lie, stand, 例如：
He always kept silent at meeting. 他開會時總保持沉默。
This matter rests a mystery. 此事仍是一個謎。
3)表像系動詞
用來表示"看起來像"這一概念，主要有seem, appear, look, 例如：
He looks tired. 他看起來很累。
He seems (to be) very sad. 他看起來很傷心。
4)感官系動詞
感官系動詞主要有feel, smell, sound, taste, 例如：
This kind of cloth feels very soft.
這種布手感很軟。
This flower smells very sweet.
這朵花聞起來很香。
5)變化系動詞
這些系動詞表示主語變成什么樣，變化系動詞主要有become, grow, turn, fall, get, go, come, run.
例如：
He became mad after that. 自那之后，他瘋了。
She grew rich within a short time. 她沒多長時間就富了。
6)終止系動詞
表示主語已終止動作，主要有prove, trun out, 表達(dá)"證實(shí)"，"變成"之意，例如：
The rumor proved false. 這謠言證實(shí)有假。
The search proved difficult. 搜查證實(shí)很難。
His plan turned out a success. 他的計(jì)劃終于成功了。(turn out表終止性結(jié)果)
英語語法：助動詞should,would的用法
1)should無詞義，只是shall的過去形式，與動詞原形構(gòu)成過去將來時，只用于第一人稱，例如：
I telephoned him yesterday to ask what I should do next week.
我昨天給他打電話，問他我下周干什么。
比較：
"What shall I do next week?" I asked.
"我下周干什么?"我問道。(可以說，shall變成間接引語時，變成了should。)
2) would也無詞義，是will的過去形式，與動詞原形構(gòu)成過去將來時，用于第二、第三人稱，例如：
He said he would come. 他說他要來。
比較：
"I will go," he said. 他說："我要去那兒。"
變成間接引語，就成了：
He said he would come.
原來的will變成would，go變成了come.。
英語語法：助動詞shall和will的用法
shall和will作為助動詞可以與動詞原形一起構(gòu)成一般將來時，例如：
I shall study harder at English. 我將更加努力地學(xué)習(xí)英語。
He will go to Shanghai. 他要去上海。
說明：
在過去的語法中，語法學(xué)家說shall用于第一人稱，will 只用于第二、第三人稱。現(xiàn)在，尤其是在口語中，will常用于第一人稱，但shall只用于第一人稱，如用于第二、第三人稱，就失去助動詞的意義，已變?yōu)榍閼B(tài)動詞，試比較:
He shall come. 他必須來。(shall有命令的意味。)
He will come. 他要來。(will只與動詞原形構(gòu)成一般將來時。)
英語語法：非謂語動詞例題及十大解題原則
非謂語動詞主要包括to do, -ing和-ed三種形式，可是其用法非常廣泛，它不僅是高考單項(xiàng)選擇題測試的一個重點(diǎn)，而且也是完形填空、閱讀理解、短文改錯的重要考查內(nèi)容。為了能更好地掌握非謂語動詞的用法，筆者在教學(xué)實(shí)踐中總結(jié)出十條實(shí)用的解題原則，并且還用相關(guān)的題目來解釋這些原則。根據(jù)這些原則，相信同學(xué)們可以輕松地應(yīng)對非謂語動詞。
原則一、兩個句子必須要用連詞連接，如果沒有連詞連接，則需要用非謂語動詞
例1. _________ many times, but he still couldn't understand it.
A. Having been told B. Having told
C. He had been told D. Though he had been told
例2._________ many times, he still couldn't understand it.
A. Having been told B. Having told
C. He had been told D. Though he had told
解析：例1中有連詞but連接，表明前后都是句子，所以答案為C。
例2中后面是一個句子，而且沒有連詞，所以前面不是句子，應(yīng)該用非謂語動詞，根據(jù)句意此處為被動，所以答案為A。
原則二、不及物動詞無-ed形式非謂語動詞，及物動詞有賓語時用-ing形式，無賓語時用-ed形式
例3. ____________ in the mountains for a week, the two students were finally saved by the local police.
A. Having lost B. Lost C. Being lost D. Losing
解析：lose為及物動詞，現(xiàn)在后面沒有賓語，所以用-ed形式，答案為B。
例4. __________, I really believe that I'd prefer not to make any change now.
A. Considered all the possibilities
B. Taking all the possibilities into consideration
C. Taken all the possibilities into consideration
D. Giving all the possibilities

原則三、being done 表示“正在被”，一般不作狀語，只作定語。非謂語動詞的完成時形式to have done或having done強(qiáng)調(diào)該動作發(fā)生在句子謂語動詞之前
例5. __ to reach them on the phone, we sent an email instead.
A. Fail B. Failed C. To fail D. Having failed
解析：根據(jù)句意“我們沒有打通電話，就給他們發(fā)了個郵件”，沒有打通電話應(yīng)該發(fā)生在發(fā)郵件之前，所以用having done，答案為D。
例6. Tim Bemers-Lee is generally considered _____ the World Wide Web, on which all the information is shared by all.
A. to have founded B. having founded
C. founding D. to found
解析：根據(jù)句意，Tim Bemers-Lee創(chuàng)立萬維網(wǎng)應(yīng)該是過去的事情，而且be considered后面應(yīng)該用動詞不定式，所以應(yīng)該用to have done，答案為A。
原則四、非謂語動詞作定語時，表示將來用-to do，表正在進(jìn)行用-ing，表示已經(jīng)完成用-ed
例7. The play_____ next month aims mainly to reflect the local culture.
A.produced B.being produced
C.to be produced D.having been produced
解析：根據(jù)本題中的時間狀語next month，可知the play將要于下月被創(chuàng)作出來，表將來應(yīng)該用to do，所以答案為C。

解析：根據(jù)“非謂語動詞作狀語，其邏輯主語必須和句子主語保持一致”的原則，watching的邏輯主語應(yīng)和后面句子主語一致，所以句子主語應(yīng)為“we”，答案為C。
例18. The children went home from the grammar school, their lessons ____ for the day.
A. finishing B. finished C. had finished D. were finished
