高中生語(yǔ)法基礎(chǔ)大全很好用的哦

1、高中生英語(yǔ)語(yǔ)法基礎(chǔ)大全詞法第1章 主謂一致一.概念:主謂一致是指：1） 語(yǔ)法形式上要一致，即單復(fù)數(shù)形式與謂語(yǔ)要一致。2） 意義上要一致，即主語(yǔ)意義上的單復(fù)數(shù)要與謂語(yǔ)的單復(fù)數(shù)形式一致。3） 就近原則，即謂語(yǔ)動(dòng)詞的單復(fù)形式取決于最靠近它的詞語(yǔ)， 一般來(lái)說(shuō)，不可數(shù)名詞用動(dòng)詞單數(shù)，可數(shù)名詞復(fù)數(shù)用動(dòng)詞復(fù)數(shù)。例如： There is much water in the thermos. 但當(dāng)不可數(shù)名詞前有表示數(shù)量的復(fù)數(shù)名詞時(shí)，謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式。例如： Ten thousand tons of coal were produced last year.二.相關(guān)知識(shí)點(diǎn)精講1.并列結(jié)構(gòu)作主語(yǔ)時(shí)謂語(yǔ)用復(fù)數(shù)，例如

2、： Reading and writing are very important. 讀寫(xiě)很重要。 注意：當(dāng)主語(yǔ)由and連結(jié)時(shí)，如果它表示一個(gè)單一的概念，即指同一人或同一物時(shí)，謂語(yǔ)動(dòng)詞用單數(shù)，and 此時(shí)連接的兩個(gè)詞前只有一個(gè)冠詞。例如： The iron and steel industry is very important to our life. 鋼鐵工業(yè)對(duì)我們的生活有重要意義。典型例題 The League secretary and monitor _ asked to make a speech at the meeting. A. isB. was C. are D. were答

3、案B. 注： 先從時(shí)態(tài)上考慮。這是過(guò)去發(fā)生的事情應(yīng)用過(guò)去時(shí)，先排除A.，C。本題易誤選D，因?yàn)門(mén)he League secretary and monitor 好象是兩個(gè)人，但仔細(xì)辨別，monitor 前沒(méi)有the，在英語(yǔ)中，當(dāng)一人兼數(shù)職時(shí)只在第一個(gè)職務(wù)前加定冠詞。后面的職務(wù)用and 相連。這樣本題主語(yǔ)為一個(gè)人，所以應(yīng)選B。2. 主謂一致中的靠近原則 1)當(dāng)there be 句型的主語(yǔ)是一系列事物時(shí)，謂語(yǔ)應(yīng)與最鄰近的主語(yǔ)保持一致。例如：There is a pen, a knife and several books on the desk. 桌上有一支筆、一把小刀和幾本書(shū)。There are

4、 twenty boy-students and twenty-three girl-students in the class.班上有二十個(gè)男孩，二十三個(gè)女孩。2）當(dāng)either or 與neither nor，連接兩個(gè)主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞與最鄰近的主語(yǔ)保持一致。如果句子是由here, there引導(dǎo)，而主語(yǔ)又不止一個(gè)時(shí)，謂語(yǔ)通常也和最鄰近的主語(yǔ)一致。例如：Either you or she is to go. 不是你去，就是她去。Here is a pen, a few envelops and some paper for you. 給你筆、信封和紙。3.謂語(yǔ)動(dòng)詞與前面的主語(yǔ)一致 當(dāng)主語(yǔ)有w

5、ith, together with, like, except, but, no less than, as well as 等詞組成的短語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞與前面的主語(yǔ)部分一致。例如： The teacher together with some students is visiting the factory. 教師和一些學(xué)生在參觀(guān)工廠(chǎng)。 He as well as I wants to go boating.他和我想去劃船。4. 謂語(yǔ)需用單數(shù)的情況1）代詞each以及由every, some, no, any等構(gòu)成的復(fù)合代詞作主語(yǔ)時(shí)，或主語(yǔ)中含有each, every時(shí), 謂語(yǔ)需用單數(shù)。例如

6、： Each of us has a tape-recorder. 我們每人都有錄音機(jī)。 There is something wrong with my watch. 我的表壞了。2）當(dāng)主語(yǔ)是一本書(shū)或一條格言時(shí)，謂語(yǔ)動(dòng)詞常用單數(shù)。例如： The Arabian Night is a book known to lovers of English. 天方夜譚是英語(yǔ)愛(ài)好者熟悉的一本書(shū)。3）表示金錢(qián)，時(shí)間，價(jià)格或度量衡的復(fù)合名詞作主語(yǔ)時(shí)，通常把這些名詞看作一個(gè)整體，謂語(yǔ)一般用單數(shù)。例如： Three weeks was allowed for making the necessary prepar

7、ations. 用三個(gè)星期來(lái)做準(zhǔn)備。 Ten yuan is enough. 十元夠了。5.指代意義決定謂語(yǔ)的單復(fù)數(shù) 1）代詞what, which, who, none, some, any, more, most, all等詞的單復(fù)數(shù)由其指代的詞的單復(fù)數(shù)決定。例如：All is right.一切順利。All are present.人都到齊了。2）集體名詞作主語(yǔ)時(shí)，謂語(yǔ)的數(shù)要根據(jù)主語(yǔ)的意思來(lái)決定。如family, audience, crew, crowd, class, company, committee等詞后，謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式時(shí)強(qiáng)調(diào)這個(gè)集體中的各個(gè)成員，用單數(shù)時(shí)強(qiáng)調(diào)該集體的整體。例

8、如： His family isnt very large. 他家成員不多。 His family are music lovers.他家個(gè)個(gè)都是音樂(lè)愛(ài)好者。 但集合名詞people, police, cattle, poultry等在任何情況下都用復(fù)數(shù)形式。例如： Are there any police around? 附近有警察嗎？3）有些名詞，如variety, number, population, proportion, majority 等有時(shí)看作單數(shù)，有時(shí)看作復(fù)數(shù)。例如： A number of +名詞復(fù)數(shù)+復(fù)數(shù)動(dòng)詞。 The number of +名詞復(fù)數(shù)+單數(shù)動(dòng)詞。 A n
