2017年6月16日GRE閱讀真題.

　　關(guān)于新GRE閱讀的真題，在這里為大家放送，希望這些真題的詳細(xì)解讀能對大家有一定的幫助，有可能為大家提供一種新的GRE閱讀思路，也有可能為為大家的薄弱環(huán)節(jié)進(jìn)行了彌補(bǔ)。

　　GRE閱讀：邏輯閱讀

　　1. 邏輯

　　從略

　　2. 閱讀

　　(1) (短閱讀) 星云膨脹

　　一開始有個(gè)人認(rèn)為星云膨脹是超新星爆炸形成的，之后有人反對，認(rèn)為膨脹星云應(yīng)包含一種密度較高的東西，他們應(yīng)該反射光，但觀測的星云不亮。下面是關(guān)于星云的形成原因介紹。

　　Many nebulae or stars form from the gravitational collapse of gas in the interstellar medium or ISM. As the material collapses under its own weight, massive stars may form in the center, and their ultraviolet radiation ionizes the surrounding gas, making it visible at optical wavelengths. Examples of these types of nebulae are the Rosette Nebula and the Pelican Nebula. The size of these nebulae, known as HII regions, varies depending on the size of the original cloud of gas. New stars are formed in the nebulas. The formed stars are sometimes known as a young, loose cluster.

　　Some nebulae are formed as the result of supernova explosions, the death throes of massive, short-lived stars. The materials thrown off from the supernova explosion are ionized by the energy and the compact object that it can produce. One of the best examples of this is the Crab Nebula, in Taurus. The supernova event was recorded in the year 1054 and is labelled SN 1054. The compact object that was created after the explosion lies in the center of the Crab Nebula and is a neutron star.

　　Other nebulae may form as planetary nebulae. This is the final stage of a low-mass star&aposs life, like Earth&aposs Sun. Stars with a mass up to 8-10 solar masses evolve into red giants and slowly lose their outer layers during pulsations in their atmospheres. When a star has lost enough material, its temperature increases and the ultraviolet radiation it emits can ionize the surrounding nebula that it has thrown off. The nebula is almost 97% hydrogen and 3% helium, plus trace amounts of other elements.

　　點(diǎn)評：在GRE考試中尤其是GRE閱讀考試，有一些題材是經(jīng)常會被涉及到的，這一點(diǎn)可以理解成這些題材槽點(diǎn)眾多，ETS可以隨便調(diào)戲;或者ETS用情專一，專愛那幾抹獨(dú)特的風(fēng)情。Whatever，這些題材目前有我們熟知的女權(quán)(本次有考到)，黑奴，氣候變化以及天文學(xué)，建議大家沒事擴(kuò)充閱讀量的時(shí)候，可以有意識的多了解下這些方面的內(nèi)容，事實(shí)上，在天文學(xué)里面，超新星，白矮星，中子星，黑洞，星云，星塵，宇宙大爆炸這些都已經(jīng)考過并且未來仍然可能繼續(xù)考，現(xiàn)成的網(wǎng)絡(luò)資源比如Wikipedia完全可以發(fā)揮出用武之地。

　　(2) (長閱讀)女權(quán)與美國憲法

　　在美國憲法中，與女權(quán)有關(guān)的憲法修正案為十九修正案(Nineteenth Amendment to the United States Constitution)，it prohibits any United States citizen from being denied the right to vote on the basis of sex. 真正在憲法意義上規(guī)定了女性擁有合法的選舉權(quán)。有興趣的可以Wiki擴(kuò)展背景。值得一提的是，目前考過的修正案還有大名鼎鼎的十四以及小名鼎鼎的十五。下面是簡介，具體還是看Wiki比較全面。

　　The Fourteenth Amendment (Amendment XIV) to the United States Constitution was adopted on July 9, 1868, as one of the Reconstruction Amendments. The amendment addresses citizenship rights and equal protection of the laws, and was proposed in response to issues related to former slaves following the American Civil War.

　　The Fifteenth Amendment (Amendment XV) to the United States Constitution prohibits the federal and state governments from denying a citizen the right to vote based on that citizen&aposs "race, color, or previous condition of servitude"
