GRE閱讀備考新手需糾正學(xué)習(xí)思路

1、GRE閱讀備考新手需糾正學(xué)習(xí)思路 GRE閱讀備考新手需糾正學(xué)習(xí)思路 細(xì)數(shù)4個不可或缺的備考思路，下面就和大家分享，來欣賞一下吧。 理解文章的意思 關(guān)于這部分的解釋是，我們拿到新GRE閱讀材料，第一件事就是要理解全文的大概意思，要明白作者在講什么，想表明什么，做到心中有數(shù)才能合理做題。GRE閱讀速讀提高不上去很大程度上是因為考生還不習(xí)慣英語到自己語言的理解，需要一個切換理解的時間。比如看到一個詞，要先想到這個詞的意思，然后理解整句話。 解決這個問題的關(guān)鍵就是需要大量的閱讀練習(xí)，在不斷地閱讀中多理解多總結(jié)，即使不是精讀也要試圖理解一片文章的大概和基本邏輯，經(jīng)過聯(lián)系使中間這個切換時間越來越短，最后達(dá)

2、到完全不需要切換的語言感覺，從而培養(yǎng)GRE閱讀語感。 關(guān)于做閱讀筆記 閱讀筆記對與GRE閱讀考試來說，有些考生可能并不需要，有些考生可能會需要做些筆記。短期來看，針對考試可以嘗試多做筆記，用自己熟悉的符號記錄或者標(biāo)注各種語言的重要信息，這樣做題時候回文定位會省事很多。 長難句的攻克 這個問題也是我們經(jīng)常拿出來講的問題，有些GRE考生可能自身覺得理解一片文章講的是什么并不可能，但是對于一些細(xì)節(jié)，和關(guān)鍵問題還是理解模糊或者無法理解的問題。出現(xiàn)這種問題的很多原因是對GRE閱讀長難句理解不透造成的，也就是在面對一些結(jié)構(gòu)復(fù)雜的長句子時無所適從。這里建議考生可以找一些針對性的GRE長難句來練習(xí)，通過不斷練

3、習(xí)和總結(jié)來提高自身的閱讀和理解能力。其外，還需要針對一些專業(yè)詞匯做特殊的記憶，比如考生不常見的地質(zhì)學(xué)、氣象學(xué)和天文學(xué)等領(lǐng)域的詞匯。 拋掉傳統(tǒng)閱讀思維 相信很多國內(nèi)考生都會有這個問題，就是在閱讀思維上會被傳統(tǒng)的習(xí)慣所禁錮。GRE閱讀考試不同于一般的閱讀考試，對于思路上不太適應(yīng)GRE閱讀思維的同學(xué)，平時練習(xí)的時候可以多積累其他方面的閱讀量，還有多看一些經(jīng)典的閱讀文章，從這些文章中找到可發(fā)掘的點，然后自己加以利用。其實通過訓(xùn)練，大家就可以發(fā)現(xiàn)自己的閱讀思維會有一個很大提高。 以上就是為各位考生的關(guān)于GRE閱讀提分新標(biāo)準(zhǔn)的介紹，希望考生積極做好備考工作，及時調(diào)整好狀態(tài)，努力在新GRE閱讀考試中取得理想

4、的成績! The molecules of carbon dioxide in the Earths atmosphere affect the heat balance of the Earth by acting as a one-way screen. Although these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concentrated, to pass through, they absorb some of the longer-wav

5、elength, infrared emissions radiated from the Earths surface, radiation that would otherwise be transmitted back into space. For the Earth to maintain a constant average temperature, such emissions from the pla must balance ining solar radiation. If there were no carbon dioxide in the atmosphere, he

6、at would escape from the Earth much more easily. The surface temperature would be so much lower that the oceans might be a solid mass (solid mass: 實體) of ice. Today, however, the potential problem is too much carbon dioxide. The burning of fossil fuels and the clearing of forests have increased atmo

7、spheric carbon dioxide by about 15 percent in the last hundred years, and we continue to add carbon dioxide to the atmosphere. Could the increase in carbon dioxide cause a global rise in average temperature, and could such a rise have serious consequences for human society? Mathematical models that

8、allow us to calculate the rise in temperature as a function of the increase indicate that the answer is probably yes. Under present conditions a temperature of-18 can be observed at an altitude of 5 to 6 kilometers above the Earth. Below this altitude (called the radiating level), the temperature in

9、creases by about 6 per kilometer approaching the Earths surface, where the average temperature is about 15. An increase in the amount of carbon dioxide means that there are more molecules of carbon dioxide to absorb infrared radiation. As the capacity of the atmosphere to absorb infrared radiation i

10、ncreases, the radiating level and the temperature of the surface must rise. One mathematical model predicts that doubling the atmospheric carbon dioxide would raise the global mean surface temperature by 2.5. This model assumes that the atmospheres relative humidity (relative humidity: n.相對濕度) remai

11、ns constant and the temperature decreases with altitude at a rate of 6.5 per kilometer. The assumption of constant relative humidity is important, because water vapor in the atmosphere is another efficient absorber of radiation at infrared wavelengths. Because warm air can hold more moisture than co

12、ol air, the relative humidity will be constant only if the amount of water vapor in the atmosphere increases as the temperature rises. Therefore, more infrared radiation would be absorbed and reradiated back to the Earths surface. The resultant warming at the surface could be expected to melt snow a

Some modern anthropologists hold that biological evolution has shaped not only human morphology but also human behavior. The role

23、those anthropologists ascribe to evolution is not of dictating the details of human behavior but one of imposing constraintsways of feeling, thinking, and acting that “e naturally” in archetypal situations in any culture. Our “frailties”emotions and motives such as rage, fear, greed, gluttony, joy,

24、lust, lovemay be a very mixed assortment, but they share at least one immediate quality: we are, as we say, “in the grip” of them. And thus they give us our sense of constraints. Unhappily, some of those frailtiesour need for ever-increasing security among themare presently maladaptive. Yet beneath

25、the overlay of cultural detail, they, too, are said to be biological in direction, and therefore as natural to us as are our appendixes. We would need to prehend thoroughly their adaptive origins in order to understand how badly they guide us now. And we might then begin to resist their pressure. 24

The primary purpose of the passage is to present (A) a position on the foundations of human behavior and on what those foundations imply (B) a theory outlining the parallel development of human morphology and of human behavior (C) a diagnostic test for separating biologically determined behavior p

The author implies that control to any extent over the “frailties” that constrai

Which of the following most probably provides an appropriate analo

Declaring that he was opposed to using this unusual animal husbandry technique to clone humans, he ordered that federal funds not be used for such an experiment-although no one had proposed to do so-and asked an independent panel of experts chaired by Princeton President Harold Shapiro to report back to the White House in 90 days with remendations for a national policy on human cloning
