托福阅读高分必备：形容词性从句
托福阅读文段中，大多数都包含着一些形容词性从句，虽然在中没有直接考察语法的题型，不过，如果大家对一些从句分析不清，很有可能影响题意理解。下面，新东方网托福频道为您整理托福阅读中形容词性从句的表现及用法，希望能帮助大家取得托福高分。
定语从句(Attributive Clauses)在句中作定语，其作用是修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句。通常定语从句皆置于它所修饰的名词或代词之后，被修饰的名词或代词叫做先行词(antecedent)，而引导定语从句的词称为关联词。
关联词常有3个作用：连接作用，引导定语从句;代替先行词;在定语从句中担当一个成分。关联词为关系代词和关系副词。关系代词在定语从句中可以用作主语、宾语、定语等;关系副词在定语从句中只用作状语。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是关系代词which引导的定语从句，用以修饰which的先行词factor, which在从句中用作主语)
★ 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是关系副词where引导的定语从句，用以修饰where的先行词regions, where在从句中用作地点状语)
定语从句一般紧跟在其先行词之后。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.(关系代词that引导的定语从句紧跟其先行词artificial irrigation systems之后)
有时也可以与先行词分离。如：
★ A new teacher will come tomorrow, who will teach you Chinese.(关系代词who引导的定语从句与其先行词teacher分离)
用作关联词的关系代词有that, which, who, whom, whose, as等，但在此提醒考生们绝对没有“what”。who, whom, whose指人，who是主格，在定语从句中用作主语(在非正式英语中也可以用作宾语，并且用作宾语时可以省去不用);whom是宾格，在定语从句中用作宾语(也可以省去不用);whose是属格，在定语从句中用作定语(有时也可以指物)。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.(主格关系代词who在从句中作主语)
★ The man who he talked about is a professor.(在非正式英语中who代替了whom,也可以省去不用)
★ He doesn't like the girl whom you refer to.(宾格关系代词whom在从句中用作宾语，也可以省去不用)
★ The children whose parents give priority to work may feel lonely and alienated.(属格关系代词whose在定语从句中用作定语，指人)
★ The car whose wheels have been stolen was bought yesterday.(属格关系代词whose在定语从句中用作定语，指物，即car，可以用of which代替，但后者较为正式)
That在定语从句中既可以用作主语，也可以用作宾语(在非正式文体中可省去);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.(关系代词that在定语从句中用作主语，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.(关系代词that在定语从句中用作宾语，指物)
★ The students that hold a foreign degree seem to be more confident and independent.(关系代词that在定语从句中用作主语，指人)
which在定语从句中既可以用作主语，也可以用作宾语;一般皆指物(在非正式文体中可省去)。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.(关系代词which在定语从句中用作主语)
★ Those surveyed had experienced chronic illnesses, for which orthodox medicine had been able to provide little relief.(关系代词which在定语从句中用作宾语，可以省去)
which在从句中也可以被用作定语和表语。如：
★ His money had been stolen, which news annoyed him.(关系代词which在定语从句中用作定语)
★ They were completely mistrusted, which in fact, they were.(关系代词which在定语从句中用作表语)
关系代词在从句中用作介词宾语时，介词可以位于从句之首，也可以位于从句之末。但以位于从句之首较为正式。如：
★ This has been encouraged through programs of language classes fro children and through ‘apprentice' scheme, in which the endangered language is used as the medium of instruction to teach people a traditional skill.(关系代词which在定语从句中用作介词in的宾语，介词位于定语从句之首，即which之前)
★ This has been encouraged through programs of language classes fro children and through ‘apprentice' scheme, which the endangered language is used as the medium of instruction to teach people a traditional skill in.(介词in位于定语从句之首，which在此可以省去)
像during, except或者表示分割作用的of等介词通常放在关系代词的前面。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.
关系代词who和that用作介词宾语时，介词须置于句末。如：
★ The writer you referred to was an unknown writer.(关系代词who用作介词to的宾语，介词to须位于定语从句之末，who在口语中可以省去)
★ This is the problem that he has been complaining about.(关系代词that用作介词about的宾语，介词about须位于定语从句之末)
有时定语从句中还有其他成分，介词则位于定语从句之中。如：
This is the engineer who he cooperated with in the project.
先行词指人时，关系代词既可以用who, 也可以用that。但关系代词在定语从句中用作主语时，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等先行词多用关系代词who)
★ It is Tom who should be punished.(在强调结构中，指人时多用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.
托福阅读都考哪些语法点?
1.形容词
形容词修饰名词或代词，说明事物或人的性质或特征。通常，可将形容词分成性质形容词和叙述形容词两类，其位置不一定都放在名词前面。形容词是修饰回答像"what kind of" 或 "which?" 或 "whose?" 这类的问题。在使用时要注意与副词的区分。
1)以-ly结尾的形容词：friendly， deadly， lovely， lonely， likely， lively， ugly， brotherly
2)以-ly 结尾既为形容词，也为副词：daily， weekly， monthly， yearly， early
2.副词
副词通常修饰动词，形容词，副词或其他结构。(它也可以修饰另一个副词或一个形容词，但是这种情况托福[微博]考试里是比较少见的。)副词经常回答"how?"
正确的位置：
1) 在动词之前;在be动词、助动词之后。
2) 有多个助动词时，副词一般放在第一个助动词后。
3) 方式副词well， badly， hard等只放在句尾。He speaks English well。
另外，
1) 副词very可修饰形容词，但不能修饰动词。
I very like English. (×)
I like English very much. (√)
2) 副词enough要放在形容词的后面，形容词enough放在名词前后都可。
3.比较
当比较两个事物时，用比较级，也就是-er形式或者用修饰词less和more。当比较多于两个以上的事物时，用最高级，也就是-est形式或者做most和least 修饰。
4.措辞错误
像包括its/it's，affect/effect，lie/lay这类长相类似的词常常容易被错用，从而引起审阅者的困惑。如果你不能确定如何用这些词的话，就尽量避免使用。
5.双重否定
与中文不同，在英语里，双重否定很容易出问题，类似于"not none"，"hardly none"和"not never"这样的双重否定都是不正确的。
托福阅读真题
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.
