托福閱讀語(yǔ)法技巧：形容詞+動(dòng)詞不定式
帶星號(hào)的形容詞也可與that從句連用，有時(shí)that…should更常見(jiàn)。
在B-E節(jié)中句子用it引導(dǎo)的結(jié)構(gòu)。如果it+be…前的動(dòng)詞是find(發(fā)現(xiàn))/think(想)/be-lieve(相信)等，有時(shí)可將that及動(dòng)詞be省略：
He found that it was impossible to study at home.相當(dāng)于：
He found it impossible to study at home.
他覺(jué)得不可能在家學(xué)習(xí)。
1 it+be+形容詞(+of+賓語(yǔ))+動(dòng)詞不定式結(jié)構(gòu)主要與下列各類形容詞連用：

(b)組形容詞后的of+賓語(yǔ)結(jié)構(gòu)可省略。有時(shí)該結(jié)構(gòu)在(a)組形容詞后也可省去，但good和nice除外。(后二者如果省略of+賓語(yǔ)則會(huì)改變good和nice的意義。參見(jiàn)E。)
2代詞+be+形容詞+名詞+動(dòng)詞不定式既可以與上面的形容詞連用，又可以與下列形容詞連用：astonishing_令人驚訝的)，curious_奇怪的)，extraordinary_不尋常的)，funny_(=strange_奇的)，odd_怪的)，queer_怪的)，surpris-ing_令人驚訝的)等。此外還有pointless(無(wú)意義的)，useful(有用的)和useless(無(wú)用的)也可以這樣使用。

that從句的例句如：

托福閱讀高分必備：形容詞性從句
托福閱讀文段中，大多數(shù)都包含著一些形容詞性從句，雖然在中沒(méi)有直接考察語(yǔ)法的題型，不過(guò)，如果大家對(duì)一些從句分析不清，很有可能影響題意理解。下面，新東方網(wǎng)托福頻道為您整理托福閱讀中形容詞性從句的表現(xiàn)及用法，希望能幫助大家取得托福高分。
定語(yǔ)從句(Attributive Clauses)在句中作定語(yǔ)，其作用是修飾主句的某個(gè)名詞性成分，相當(dāng)于形容詞，所以又稱為形容詞性從句。通常定語(yǔ)從句皆置于它所修飾的名詞或代詞之后，被修飾的名詞或代詞叫做先行詞(antecedent)，而引導(dǎo)定語(yǔ)從句的詞稱為關(guān)聯(lián)詞。
關(guān)聯(lián)詞常有3個(gè)作用：連接作用，引導(dǎo)定語(yǔ)從句;代替先行詞;在定語(yǔ)從句中擔(dān)當(dāng)一個(gè)成分。關(guān)聯(lián)詞為關(guān)系代詞和關(guān)系副詞。關(guān)系代詞在定語(yǔ)從句中可以用作主語(yǔ)、賓語(yǔ)、定語(yǔ)等;關(guān)系副詞在定語(yǔ)從句中只用作狀語(yǔ)。如：
★ One factor which may help ensure that some endangered languages do not die out completely is people's increasing appreciation of their cultural identity.(which may help ensure that some endangered languages do not die out completely是關(guān)系代詞which引導(dǎo)的定語(yǔ)從句，用以修飾which的先行詞factor, which在從句中用作主語(yǔ))
★ And even in regions where new projects seem warranted, we must find ways to meet demands with fewer resources, respecting ecological criteria and to a smaller budget.(where new projects seem warranted是關(guān)系副詞where引導(dǎo)的定語(yǔ)從句，用以修飾where的先行詞regions, where在從句中用作地點(diǎn)狀語(yǔ))
定語(yǔ)從句一般緊跟在其先行詞之后。如：
★ Food production has kept pace with soaring populations mainly because of the expansion of artificial irrigation systems that make possible the growth of 40% of the world's food.(關(guān)系代詞that引導(dǎo)的定語(yǔ)從句緊跟其先行詞artificial irrigation systems之后)
有時(shí)也可以與先行詞分離。如：
★ A new teacher will come tomorrow, who will teach you Chinese.(關(guān)系代詞who引導(dǎo)的定語(yǔ)從句與其先行詞teacher分離)
用作關(guān)聯(lián)詞的關(guān)系代詞有that, which, who, whom, whose, as等，但在此提醒考生們絕對(duì)沒(méi)有“what”。who, whom, whose指人，who是主格，在定語(yǔ)從句中用作主語(yǔ)(在非正式英語(yǔ)中也可以用作賓語(yǔ)，并且用作賓語(yǔ)時(shí)可以省去不用);whom是賓格，在定語(yǔ)從句中用作賓語(yǔ)(也可以省去不用);whose是屬格，在定語(yǔ)從句中用作定語(yǔ)(有時(shí)也可以指物)。如：
★ The American zoologist Donald Griffin, who was largely responsible for the discovery of sonar in bats, coined the term ‘echolocation' to cover both sonar and radar, whether used by animals or by human instruments.(主格關(guān)系代詞who在從句中作主語(yǔ))
★ The man who he talked about is a professor.(在非正式英語(yǔ)中who代替了whom,也可以省去不用)
★ He doesn't like the girl whom you refer to.(賓格關(guān)系代詞whom在從句中用作賓語(yǔ)，也可以省去不用)
★ The children whose parents give priority to work may feel lonely and alienated.(屬格關(guān)系代詞whose在定語(yǔ)從句中用作定語(yǔ)，指人)
★ The car whose wheels have been stolen was bought yesterday.(屬格關(guān)系代詞whose在定語(yǔ)從句中用作定語(yǔ)，指物，即car，可以用of which代替，但后者較為正式)
That在定語(yǔ)從句中既可以用作主語(yǔ)，也可以用作賓語(yǔ)(在非正式文體中可省去);既可以指人，也可以指物。如：
★ These methods include strength training that duplicate what they are doing in their running events as well as plyometrics, a technique pioneered in the former Soviet Union.(關(guān)系代詞that在定語(yǔ)從句中用作主語(yǔ)，指物)
★ Put another way, basic heath-care is now recognized as a ‘public good', rather than a ‘private good' that one is expected to buy for oneself.(關(guān)系代詞that在定語(yǔ)從句中用作賓語(yǔ)，指物)
★ The students that hold a foreign degree seem to be more confident and independent.(關(guān)系代詞that在定語(yǔ)從句中用作主語(yǔ)，指人)
which在定語(yǔ)從句中既可以用作主語(yǔ)，也可以用作賓語(yǔ);一般皆指物(在非正式文體中可省去)。如：
★ Eye position in freshwater dolphins, which often swim on their side or upside down while feeding, suggests that what vision they have stereoscopic forward and upward.(關(guān)系代詞which在定語(yǔ)從句中用作主語(yǔ))
★ Those surveyed had experienced chronic illnesses, for which orthodox medicine had been able to provide little relief.(關(guān)系代詞which在定語(yǔ)從句中用作賓語(yǔ)，可以省去)
which在從句中也可以被用作定語(yǔ)和表語(yǔ)。如：
★ His money had been stolen, which news annoyed him.(關(guān)系代詞which在定語(yǔ)從句中用作定語(yǔ))
★ They were completely mistrusted, which in fact, they were.(關(guān)系代詞which在定語(yǔ)從句中用作表語(yǔ))
關(guān)系代詞在從句中用作介詞賓語(yǔ)時(shí)，介詞可以位于從句之首，也可以位于從句之末。但以位于從句之首較為正式。如：
★ This has been encouraged through programs of language classes fro children and through ‘a(chǎn)pprentice' scheme, in which the endangered language is used as the medium of instruction to teach people a traditional skill.(關(guān)系代詞which在定語(yǔ)從句中用作介詞in的賓語(yǔ)，介詞位于定語(yǔ)從句之首，即which之前)
★ This has been encouraged through programs of language classes fro children and through ‘a(chǎn)pprentice' scheme, which the endangered language is used as the medium of instruction to teach people a traditional skill in.(介詞in位于定語(yǔ)從句之首，which在此可以省去)
像during, except或者表示分割作用的of等介詞通常放在關(guān)系代詞的前面。如：
★ The years during which he was away were long years to her.
★ He wrote many books, some of which you will read some day.
關(guān)系代詞who和that用作介詞賓語(yǔ)時(shí)，介詞須置于句末。如：
★ The writer you referred to was an unknown writer.(關(guān)系代詞who用作介詞to的賓語(yǔ)，介詞to須位于定語(yǔ)從句之末，who在口語(yǔ)中可以省去)
★ This is the problem that he has been complaining about.(關(guān)系代詞that用作介詞about的賓語(yǔ)，介詞about須位于定語(yǔ)從句之末)
有時(shí)定語(yǔ)從句中還有其他成分，介詞則位于定語(yǔ)從句之中。如：
This is the engineer who he cooperated with in the project.
先行詞指人時(shí)，關(guān)系代詞既可以用who, 也可以用that。但關(guān)系代詞在定語(yǔ)從句中用作主語(yǔ)時(shí)，多用主格who。如：
★ Beyond the practical need to make order out of chaos, the rise of the dictionaries is associated with the rise of the English middle class, who were anxious to define and circumscribe the various world to conquer.(persons, those, people等先行詞多用關(guān)系代詞who)
★ It is Tom who should be punished.(在強(qiáng)調(diào)結(jié)構(gòu)中，指人時(shí)多用who)
★ The American zoologist Donald Griffin, who was largely responsible for the discovery of sonar in bats, coined the term ‘echolocation' to cover both sonar and radar, whether used by animals or by human instruments.
托福閱讀都考哪些語(yǔ)法點(diǎn)?
1.形容詞
形容詞修飾名詞或代詞，說(shuō)明事物或人的性質(zhì)或特征。通常，可將形容詞分成性質(zhì)形容詞和敘述形容詞兩類，其位置不一定都放在名詞前面。形容詞是修飾回答像"what kind of" 或 "which?" 或 "whose?" 這類的問(wèn)題。在使用時(shí)要注意與副詞的區(qū)分。
1)以-ly結(jié)尾的形容詞：friendly， deadly， lovely， lonely， likely， lively， ugly， brotherly
2)以-ly 結(jié)尾既為形容詞，也為副詞：daily， weekly， monthly， yearly， early
2.副詞
副詞通常修飾動(dòng)詞，形容詞，副詞或其他結(jié)構(gòu)。(它也可以修飾另一個(gè)副詞或一個(gè)形容詞，但是這種情況托福[微博]考試?yán)锸潜容^少見(jiàn)的。)副詞經(jīng)?；卮?quot;how?"
正確的位置：
1) 在動(dòng)詞之前;在be動(dòng)詞、助動(dòng)詞之后。
2) 有多個(gè)助動(dòng)詞時(shí)，副詞一般放在第一個(gè)助動(dòng)詞后。
3) 方式副詞well， badly， hard等只放在句尾。He speaks English well。
另外，
1) 副詞very可修飾形容詞，但不能修飾動(dòng)詞。
I very like English. (×)
I like English very much. (√)
2) 副詞enough要放在形容詞的后面，形容詞enough放在名詞前后都可。
3.比較
當(dāng)比較兩個(gè)事物時(shí)，用比較級(jí)，也就是-er形式或者用修飾詞less和more。當(dāng)比較多于兩個(gè)以上的事物時(shí)，用最高級(jí)，也就是-est形式或者做most和least 修飾。
4.措辭錯(cuò)誤
像包括its/it's，affect/effect，lie/lay這類長(zhǎng)相類似的詞常常容易被錯(cuò)用，從而引起審閱者的困惑。如果你不能確定如何用這些詞的話，就盡量避免使用。
5.雙重否定
與中文不同，在英語(yǔ)里，雙重否定很容易出問(wèn)題，類似于"not none"，"hardly none"和"not never"這樣的雙重否定都是不正確的。
托福閱讀真題
A survey is a study, generally in the form of an interview or a questionnaire that provides information concerning how people think and act. In the United States, the best-known surveys are the Gallup poll and the Harris poll. As anyone who watches the news during presidential campaigns knows, these polls have become an important part of political life in the United States.
North Americans are familiar with the many person-on-the-street interviews on local television news shows. While such interviews can be highly entertaining, they are not necessarily an accurate indication of public opinion. First, they reflect the opinions of only those people who appear at a certain location. Thus, such samples can be biased in favor of commuters, middle-class shoppers, or factory workers, depending on which area the newspeople select. Second, television interviews tend to attract outgoing people who are willing to appear on the air, while they frighten away others who may feel intimidated by a camera. A survey must be based on a precise, representative sampling if it is to genuinely reflect a broad range of the population.
In preparing to conduct a survey, sociologists must exercise great care in the wording of questions. An effective survey question must be simple and clear enough for people to understand it. It must also be specific enough so that there are no problems in interpreting the results. Even questions that are less structured must be carefully phrased in order to elicit the type of information desired. Surveys can be indispensable sources of information, but only if the sampling is done properly and the questions are worded accurately.
There are two main forms of surveys: the interview and the questionnaire. Each of these forms of survey research has its advantages. An interviewer can obtain a high response rate because people find it more difficult to turn down a personal request for an interview than to throw away a written questionnaire. In addition, an interviewer can go beyond written questions and probe for a subject's underlying feelings and reasons. However, questionnaires have the advantage of being cheaper and more consistent.
