科学的托福考试方法

关于阅读方法本文只是对在有限时间内有效阅读托福文章的方法进行一个简单的介绍。阅读技巧，特别是速度技巧中，有两个重要的方法：Skimming&Scanning.

Skimming是只看主要大意的速读。一篇文章的大意是有重点的。比如，当出现first second的这种归类总结的地方，或because，as a result这样的因果关系，或是 but，however的语意转折处，都需要格外留心。托福文章讲述主要观点之后通常会有for example来佐证，如果看懂了主要观点，那么对示例所用的时间和精力就不需要太多了。Skimming的技巧在第一遍阅读文章意图抓住文章大意时是非常重要的。

Scanning是“扫描”，但具体到阅读中，大家最熟悉的莫过于查词典时。在有意识地去查某个生词的时候，我们不会去把它所在的页上每一个字都看一遍才找到想要的。几乎眼睛对词典中的一页扫一下，脑中只有要找的字，看到它，其他的地方都像没有看到一样。在托福的阅读中，scanning的技巧在回答问题时，根据题干中问到的内容，在文章中scan，可以帮助考生准确地定位，找到答案。

以上两种是在托福阅读中最常用也是最有效的技巧。

托福的文章长度大多在300-400字之间。以平均每篇读10分钟计算，按照每分钟阅读150字的速度，一篇文章从头到尾通读，至少需2-3分钟。这可了解文章的大意，但不一定保证读得透彻。在第一遍通读的过程中，考生不要期望每个字都一定要理解，遇到不懂的字不必多逗留或苦思冥想可能的意思，这样会浪费时间的。只需一直往下看，用前面介绍到的skimming原则，掌握文章的主旨即可。这个过程中，文章的第一段，尤其是每段的第一句话往往起着提纲挈领或起承转合的作用，是阅读时要多留心的地方。

托福阅读真题1

Scientists have discovered that for the last 160,000 years, at least, there has been a consistent relationship between the amount of carbon dioxide in the air and the average temperature of the planet. The importance of carbon dioxide in regulating the Earth's temperature was confirmed by scientists working in eastern Antarctica. Drilling down into a glacier, they extracted a mile-long cylinder of ice from the hole. The glacier had formed as layer upon layer of snow accumulated year after year. Thus drilling into the ice was tantamount to drilling back through time.

The deepest sections of the core are composed of water that fell as snow 160,000 years ago. Scientists in Grenoble, France, fractured portions of the core and measured the composition of ancient air released from bubbles in the ice. Instruments were used to measure the ratio of certain isotopes in the frozen water to get an idea of the prevailing atmospheric temperature at the time when that particular bit of water became locked in the glacier.

The result is a remarkable unbroken record of temperature and of atmospheric levels of carbon dioxide. Almost every time the chill of an ice age descended on the planet, carbon dioxide levels dropped. When the global temperature dropped 9 F (5 C°), carb°on dioxide levels dropped to 190 parts per million or so. Generally, as each ice age ended and the Earth basked in a warm interglacial period, carbon dioxide levels were around 280 parts per million. Through the 160,000 years of that ice record, the level of carbon dioxide in the atmosphere fluctuated between 190 and 280 parts per million, but never rose much higher-until the Industrial Revolution beginning in the eighteenth century and continuing today.

There is indirect evidence that the link between carbon dioxide levels and global temperature change goes back much further than the glacial record. Carbon dioxide levels may have been much greater than the current concentration during the Carboniferous period, 360 to 285 million years ago. The period was named for a profusion of plant life whose buried remains produced a large fraction of the coal deposits that are being brought to the surface and burned today.

托福阅读真题2

Of all modern instruments, the violin is apparently one of the simplest. It consists in essence of a hollow, varnished wooden sound box, or resonator, and a long neck, covered with a fingerboard, along which four strings are stretched at high tension. The beauty of design, shape, and decoration is no accident: the proportions of the instrument are determined almost entirely by acoustical considerations. Its simplicity of appearance is deceptive. About 70 parts are involved in the construction of a violin. Its tone and its outstanding range of expressiveness make it an ideal solo instrument. No less important, however, is its role as an orchestral and chamber instrument. In combination with the larger and deeper-sounding members of the same family, the violins form the nucleus of the modern symphony orchestra.

The violin has been in existence since about 1550. Its importance as an instrument in its own right dates from the early 1600's, when it first became standard in Italian opera orchestras. Its stature as an orchestral instrument was raised further when in 1626 Louis XIII of France established at his court the orchestra known as Les vingt-quatre violins du Roy (The King's 24 Violins), which was to become widely famous later in the century.

In its early history, the violin had a dull and rather quiet tone resulting from the fact that the strings were thick and were attached to the body of the instrument very loosely. During the eighteenth and nineteenth century, exciting technical changes were inspired by such composer-violinists as Vivaldi and Tartini. Their instrumental compositions demanded a fuller, clearer, and more brilliant tone that was produced by using thinner strings and a far higher string tension. Small changes had to be made to the violin's internal structure and to the fingerboard so that they could withstand the extra strain. Accordingly, a higher standard of performance was achieved, in terms of both facility and interpretation. Left-hand technique was considerably elaborated, and new fingering patterns on the fingerboard were developed for very high notes.

1. The word standard in line 12 is closest in meaning to

(A) practical

(B) customary

(D) unusual

2. The King's 24 Violins is mentioned in line 15 to illustrate

(A) how the violin became a renowned instrument

(B) the competition in the 1600's between French and Italian orchestras

(D) why the violin was considered the only instrument suitable to be played by royalty

3. What is the main idea presented in paragraph 3?

(A) The violin has been modified to fit its evolving musical functions.

(B) The violin is probably the best known and most widely distributed musical instrument in the

world.

(D) The technique of playing the violin has remained essentially the same since the 1600's.

4. The author mentions Vivaldi and Tartini in line 19 as examples of composers whose music

(A) inspired more people to play the violin

(B) had to be adapted to the violin

(D) could be played only by their students

5. The word they in line 22 refers to

(A) Civaldi and Tartini

(B) thinner strings and a higher string tension

(D) internal structure and fingerboard

6. The word strain in line 22 is closest in meaning to

(A) struggle

(B) strength

(D) stress

7. The word Accordingly in line 23 is closest in meaning to

(A) However

(B) Consequently

(D) Ultimately

(D) were easier to play

9. According to the passage , which of the following contributes to a dull sound being produced

by a violin?

(A) A long fingerboard

(B) A small body

(D) Thick strings

10. Which of the following terms is defined in the passage ?

(A) resonator (line 2)

(B) solo (line 7)

(D) fingering patterns (lines 24-25)

Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to expand, it will negatively affect one after another of Earth's ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and run off of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have unraveled cons of evolution and irrevocably redirected its course.

Certainly, there have been periods in Earth's history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only .01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out.

However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt — time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments.

1. What does the passage mainly discuss?

(A) The causes of the extinction of the dinosaur

(B) The variety of species found in tropical rain forests.

(D) The time required for species to adapt to new environments

2. The word critical in line 1 is closest in meaning to

(A) negative

(B) essential

(D) complicated

3. The word jolting in line 5 is closest in meaning to

(A) predicted

(B) shocking

(D) illuminating

4. The author mentions the reduction of the variety of species on Earth in line 12 to suggest that

(A) new habitats can be created for species

(B) humans are often made ill by polluted water

(D) an understanding of evolution can prevent certain species from disappearing

5. The author mentions all of the following as examples of the effect of humans oil the world's

ecosystems EXCEPT

(A) destruction of the tropical rain forests

(B) habitat destruction in wetlands

(D) the introduction of new varieties of plant species

6. The author mentions the extinction of the dinosaurs in the second paragraph to emphasize

that

(A) the cause of the dinosaurs extinction is unknown

(B) Earth's climate has changed significantly since the dinosaurs' extinction,

(D) actions by humans could not stop the irreversible process of a species' extinction

7. The word magnitude in line 20 is closest in meaning to

(A) concern

(B) determination

(D) extent

8. According to the passage , natural evolutionary change is different from changes caused by

humans in that changes caused by humans

(A) are occurring at a much faster rate

(B) are less devastating to most species

(D) are reversible

9. With which of the following statements would the author be most likely to agree?

(A) Human influence on ecosystems should not be a factor in determining public policy.

(B) The extinction of a few species is an acceptable consequence of human progress.

(D) Humans should be more conscious of the influence they have on ecosystems
