托福閱讀句子要點題的分析
托福閱讀考試部分中，句子要點題對于大家來說，也是要重點突破的話題。在實際的備考中，具體的這類題目的解題要點是什么?考生們應該如何快速的掌握這些題型內(nèi)容呢?下面小編為大家整理了詳細的內(nèi)容，供大家參考!
托福閱讀句子要點題的分析
托福閱讀句子要點題，又稱托福閱讀句子簡化題，是對長難句的簡化篩出句子最精華的要點。
一般出題形式是在文章中高亮標示出一個句子，要求考生選擇與原文基本信息最接近的選項，這類題目的提問方式一般為：“Which is the following best expresses the essential information in the highlighted sentence? Incorrect answer choices change the meaning in important ways or leave out essential information.”
句子簡化題的出題思路一般分為兩類：一是對長難句的化繁為簡，即原句比較長，邏輯關系復雜，選項只保留了原句的主要信息，而省略了原句的次要信息(如同位語、例子)等;二是對相對簡單的句子的同義改寫，即原句難度不大，邏輯關系簡單，選項是原句的同義改寫。
從做題方法上來說，對于第二種出題思路的題目，考生應該采用通讀的辦法，在理解原句意思的基礎上再答題。
而針對第一種出題思路的題目，考生一般把握住原句的幾個關鍵點就可以見微知著，找到_句子簡化題的良方。
對于句子簡化題，有一些題目如果句子不長，我們做題的基本原則就是：同義替換。
找到原句中的關鍵詞在選項當中進行同義替換。如：
In evolutionary history, the development of language set humans apart from the rest of the animal kingdom. Which sentence below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
A. Humans evolved as the most powerful species after they are developed language.
B. The creation of human language has its origins in the language of animals.
C. The emergence of language distinguished early humans from other animals.
D. Humans and animals developed completed different systems of communication.
先來看題干：Which sentence below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
該題要求從選項中選擇一個能夠表達原文陰影句子核心信息的句子。
很多同學采用翻譯的方法做題，即首先翻譯原句，然后逐個翻譯四個選項。這種做法不僅浪費時間，而且對我們讀句子的能力要求極高。
更好的做法是，首先判斷句子的核心信息。
這是考題當中為數(shù)不多的原句比較簡單的句子釋義題，原句的核心概念在于強調區(qū)分(apart from)。因此找到同義替換，即是C 項當中的distinguished。但是大多數(shù)題目的原文不會是一個簡單句，多數(shù)是帶有邏輯關系的復雜句。那么簡單的同義替換技巧就無法操作了。
其實，我們在讀原句的時候并不需要完整的徹底的攝取信息，相反，我們通過快速瀏覽，只需要關注兩個關鍵點：
一是原句當中的表示程度，頻率的詞;
二是原句當中的邏輯關系。并不需要吸收所有信息，只需要快速瀏覽將所關注的信息點抓住即可，這樣便節(jié)省了大量的時間。
最后我們來回顧一下ETS對句子簡化題的出題要求，簡單來說，托福閱讀句子要點題的關鍵就在于找到原文考查句子和選項各自的關鍵信息再進行比對。
一般來說題目中干擾選項的錯誤主要體現(xiàn)在兩個方面：
一是從根本上改變了原句意思;
二是漏掉了原句中包含的重要信息。
托福閱讀模擬題的練習
Hormones in the Body
Up to the beginning of the twentieth century, the nervous system was thought to control all communication within the body and the resulting integration of behavior. Scientists had determined that nerves ran, essentially, on electrical impulses. These impulses were thought to be the engine for thought, emotion, movement, and internal processes such as digestion. However, experiments by William Bayliss and Ernest Starling on the chemical secretin, which is produced in the small intestine when food enters the stomach, eventually challenged that view. From the small intestine, secretin travels through the bloodstream to the pancreas. There, it stimulates the release of digestive chemicals. In this fashion, the intestinal cells that produce secretin ultimately regulate the production of different chemicals in a different organ, the pancreas.
Such a coordination of processes had been thought to require control by the nervous system; Bayliss and Starling showed that it could occur through chemicals alone. This discovery spurred Starling to coin the term hormone to refer to secretin, taking it from the Greek word hormon, meaning “to excite” or “to set in motion.” A hormone is a chemical produced by one tissue to make things happen elsewhere.
As more hormones were discovered, they were categorized, primarily according to the process by which they operated on the body. Some glands (which make up the endocrine system) secrete hormones directly into the bloodstream. Such glands include the thyroid and the pituitary. The exocrine system consists of organs and glands that produce substances that are used outside the bloodstream, primarily for digestion. The pancreas is one such organ, although it secretes some chemicals into the blood and thus is also part of the endocrine system.
Much has been learned about hormones since their discovery. Some play such key roles in regulating bodily processes or behavior that their absence would cause immediate death. The most abundant hormones have effects that are less obviously urgent but can be more far-reaching and difficult to track: They modify moods and affect human behavior, even some behavior we normally think of as voluntary. Hormonal systems are very intricate. Even minute amounts of the right chemicals can suppress appetite, calm aggression, and change the attitude of a parent toward a child. Certain hormones accelerate the development of the body, regulating growth and form; others may even define an individual’s personality characteristics. The quantities and proportions of hormones produced change with age, so scientists have given a great deal of study to shifts in the endocrine system over time in the hopes of alleviating ailments associated with aging.
In fact, some hormone therapies are already very common. A combination of estrogen and progesterone has been prescribed for decades to women who want to reduce mood swings, sudden changes in body temperature, and other discomforts caused by lower natural levels of those hormones as they enter middle age. Known as hormone replacement therapy (HRT), the treatment was also believed to prevent weakening of the bones. At least one study has linked HRT with a heightened risk of heart disease and certain types of cancer. HRT may also increase the likelihood that blood clots—dangerous because they could travel through the bloodstream and block major blood vessels—will form. Some proponents of HRT have tempered their enthusiasm in the face of this new evidence, recommending it only to patients whose symptoms interfere with their abilities to live normal lives.
Human growth hormone may also be given to patients who are secreting abnormally low amounts on their own. Because of the complicated effects growth hormone has on the body, such treatments are generally restricted to children who would be pathologically small in stature without it. Growth hormone affects not just physical size but also the digestion of food and the aging process. Researchers and family physicians tend to agree that it is foolhardy to dispense it in cases in which the risks are not clearly outweighed by the benefits.

托福閱讀文章要怎么做
The extreme seriousness of desertification results from the vast areas of land and the tremendous numbers of people affected, as well as from the great difficulty of reversing or even slowing the process。
很多人在看到這句話的時候，經(jīng)常翻譯為"沙漠化是源于"或者翻譯為"沙漠化導致""很多的土地與很多的人去影響的原因。 "這里面有兩個點特別容易犯錯誤，一是result from是源于的意思，而不是單純的導致的意思。二是affected在這里其實是后置定語，因此這里的意思是"被影響"，這里很多人又疑惑了，因為我們 以前看到的東西都是，人的因素導致沙漠化啊，怎么又會是被影響呢?這就是你的問題了，你被自己以前獲得的信息給影響了，你只要知道文章的作者是這么認為的 就可以了，何必把自己腦中的信息強加在本文作者身上呢?
這句話其實是一個很淺顯的例子，舉這個例子，其實就是想告訴很多考生很多時候，只是認為自己已經(jīng)把文章讀懂了，但是實際上對于文章的理解上有無 數(shù)的錯誤，這其實就是語言的細節(jié)!這些細節(jié)點要想解決靠的是什么?靠的是單詞的積累，靠的是語法的一步一步的打磨。
新托福閱讀中如果你經(jīng)常有看得懂文章，但不對題的感嘆出現(xiàn)，考生們最好還是從自身下手，去檢查自己的單詞，以及語法，如果覺得不知道從哪里下手，到底該怎么提升，建議你做做老托福的語法，而且要多分析錯題;并且多找一些文章多翻譯一下，然后按照里面給出的譯文去檢查一下自己到底哪里理解 錯了.
