托?;A(chǔ)語(yǔ)法知識(shí)講解
語(yǔ)法是托??荚嚨幕緝?nèi)容,小編整理了一些語(yǔ)法知識(shí),讓我們一起來(lái)看看吧。下面小編就和大家分享,來(lái)欣賞一下吧。
托?;A(chǔ)語(yǔ)法知識(shí)講解:被動(dòng)時(shí)態(tài)
語(yǔ)法知識(shí)也是托福備考的基本內(nèi)容,語(yǔ)法知識(shí)貫穿于聽(tīng)說(shuō)讀寫各個(gè)考試科目中。今天我們重點(diǎn)來(lái)講解的是“被動(dòng)時(shí)態(tài)”,下面就跟隨新東方在線托福網(wǎng)一起來(lái)看看具體的內(nèi)容吧!
先說(shuō)說(shuō)被動(dòng)語(yǔ)態(tài)的結(jié)構(gòu),其基本結(jié)構(gòu)為:be+動(dòng)詞的過(guò)去分詞。其與主動(dòng)語(yǔ)態(tài)在形式上的特征是選擇使用哪一種語(yǔ)態(tài)的必備常識(shí),也是解題的一種手段。
被動(dòng)語(yǔ)態(tài)區(qū)別于主動(dòng)語(yǔ)態(tài)的是謂語(yǔ)動(dòng)詞必須是及物動(dòng)詞且之后絕大多數(shù)不能夠再接賓語(yǔ),只有極少數(shù)可以接雙賓語(yǔ)的動(dòng)詞,像consider, give, call, name等就可以,比如像:She was considered a genius in painting.
小編提醒:在托??荚嚨母腻e(cuò)題中,如果在被動(dòng)句里面,動(dòng)詞(除了上面提到的接雙賓語(yǔ)的動(dòng)詞)的被動(dòng)式后面出現(xiàn)賓語(yǔ),那么在這里絕對(duì)是有錯(cuò)誤的,可將其改為主動(dòng)句,但是同樣的,在主動(dòng)句里面,如果及物動(dòng)詞后面沒(méi)有賓語(yǔ),此處肯定也是錯(cuò)誤的,可以將其改為被動(dòng)句。
其實(shí)大家可以將by視為被動(dòng)語(yǔ)態(tài)的標(biāo)志詞,在by之后的名詞短語(yǔ)是句子中動(dòng)作的施動(dòng)者,因此在題目中如果見(jiàn)到by+名詞的結(jié)構(gòu)的時(shí)候,最優(yōu)先考慮的就是被動(dòng)式,比如像:The book was written by Mark Twain.
小編提醒:在by的后面如果接的是動(dòng)名詞,那么其表示為方式、手段就不能將其視為被動(dòng)式的標(biāo)志了,并且此時(shí)的謂語(yǔ)應(yīng)該用主動(dòng)式,如:He passed the exam by cheating.而對(duì)于know來(lái)講,一般都是用be known to,而不用be know by。有點(diǎn)迷糊?沒(méi)事,我們照例來(lái)例題解析:
例:The seating of musicians in an orchestra is arranged --- to produce The desired blend of contributor from The various himself to sections.
(A) the conductor of
(B) from the conductor
(C) the conductor and
(D) by the conductor
解析:在題目中,如果不要空白處的話,句子也是很完整的,我們可以清楚的看到空格后的不定式短語(yǔ)表目的,那么可能填入的是arrange的施動(dòng)者,自然此處應(yīng)該用by來(lái)引導(dǎo),A選項(xiàng)中of不能接不定式,C選項(xiàng)不能在被動(dòng)式后面接賓語(yǔ),所以選D。
大家都知道被動(dòng)語(yǔ)態(tài)由助動(dòng)詞be加上過(guò)去分詞構(gòu)成,因此它也會(huì)有不同的時(shí)態(tài),其時(shí)態(tài)主要通過(guò)助動(dòng)詞be來(lái)表現(xiàn),在其中,對(duì)過(guò)去進(jìn)行時(shí)的表示方法大家要留意啊。比如像:The potatoes are being peeled in The machine.當(dāng)然還有其他的時(shí)態(tài),像:
The table has just been cleaned.(現(xiàn)在完成時(shí))
His passport had been changed without His notice.(過(guò)去完成時(shí))
The press conference will be held in three weeks.(一般將來(lái)時(shí))
這個(gè)我們方便大家理解,就直接上例題解析:
例:Experiment in the photography of moving objects --in both the United States and Europe well before 1900.
(A) have had been conducting
(B) were conducting
(C) had been conducted
(D) being conducted
解析:在這個(gè)句子中缺少謂語(yǔ),conduct是及物動(dòng)詞,因此后面如果沒(méi)有賓語(yǔ)的話,基于此,A和B首先接被排除了,D的分詞是不能單獨(dú)作謂語(yǔ)的,所以選C。
托福語(yǔ)法實(shí)例講解:不定代詞
一、比較both 和All
Both,either,neither都是在談到兩個(gè)人或者東西的時(shí)候用到
Both of them are right. (他們兩個(gè)人都對(duì))
You can take either book.(兩本書(shū)你可以任意挑一本)
Neither of them is going to get haircut. (他們倆誰(shuí)也不愿意理發(fā))
All of the books are worth to read. (三本書(shū)以上)
None of them is going to get haircut. (them指三個(gè)人以上)
I like any of them. (them指三個(gè)人以上)
二、None 和no
None和no都用于否定的意思。但是None是“沒(méi)有一個(gè)人或者沒(méi)有一個(gè)東西”,在句子中可以用作主語(yǔ)、賓語(yǔ)、同位語(yǔ)等。而No是“沒(méi)有”的意思,只能夠當(dāng)作形容詞用,不能夠作代詞用。
None of them knew how to do it. (不能夠說(shuō)no of them)
No women are allowed to come in.
三、another,the other,others,the others
1.在涉及到兩個(gè)人或者東西的時(shí)候,任意取一個(gè)用one,另外那個(gè)用the other(表示特指)
I have two computers; one is IBM,the other is Dell.
2.涉及到三個(gè)以上時(shí),任意取一個(gè)用one,泛指另外一個(gè)用another
Three people went to the meeting. One was a software programmer,another was a network expert, and the third was a college student.
3.涉及到三個(gè)以上時(shí),任意取一個(gè)用one,表示特指其他的那些用the others或者用
the other+名詞
Two of them go to Canada,the others go to America.
(他們中兩個(gè)人去了加拿大,其他人去了美國(guó))
Two of the students go to Canada,the other students go to America

托福閱讀提升語(yǔ)法能力要點(diǎn)分析
1.熟悉語(yǔ)法規(guī)則
對(duì)于托福閱讀,常見(jiàn)的語(yǔ)法現(xiàn)象有定語(yǔ)從句,主賓表同四個(gè)名詞性從句,以及非謂語(yǔ)動(dòng)詞。對(duì)于多數(shù)的學(xué)生而言,單個(gè)的語(yǔ)法現(xiàn)象不足以成為閱讀的障礙,真正的障礙來(lái)自于文章句子里面所體現(xiàn)的多個(gè)語(yǔ)法現(xiàn)象,也就是我們平時(shí)所說(shuō)的長(zhǎng)難句。經(jīng)常做錯(cuò)題分析的同學(xué)也明白,自己錯(cuò)題的原因并非沒(méi)有找到相關(guān)的信息,而是定位到有效信息后,沒(méi)有看懂句子的意思,導(dǎo)致錯(cuò)題。所以備考階段需要有針對(duì)性,要加強(qiáng)長(zhǎng)難句分析的訓(xùn)練,由易到難,熟練掌握語(yǔ)法規(guī)則。
2.精讀文章,分析段落結(jié)構(gòu),劃分句子成分,并翻譯文章大意
句子是語(yǔ)法的載體,在做完題目之后必須要精讀文章,把每段的段落層次劃分清楚,把比較難懂的句子單獨(dú)拿出來(lái)劃出主干部分,并翻譯出大意。在這一環(huán)節(jié),翻譯是必要的,翻譯其實(shí)就是語(yǔ)言的輸出,如果輸出的信息是正確的,那么我們的理解就是正確的,同時(shí)還有利于老師對(duì)于學(xué)生語(yǔ)法知識(shí)盲點(diǎn)的準(zhǔn)確判斷,改進(jìn)教學(xué)。
