小編寄語:英語四級(jí)六級(jí)考試,閱讀是不可或缺的一大部分,生詞多,理解難,時(shí)間少,是不少考生抱怨的問題。要想在考場(chǎng)上做好閱讀理解,必須在平常多閱讀,掌握新詞匯,提高閱讀速度。而滬江小編就為大家準(zhǔn)備了閱讀材料系列,供大家練習(xí)。

我們的這個(gè)閱讀系列旨在為大家提供一些閱讀材料,不一定跟四六級(jí)考試的難度、篇幅、內(nèi)容完全一樣。對(duì)于很多童鞋糾結(jié)這是四級(jí)還是六級(jí)范圍的閱讀,其實(shí)沒有必要。如果大家覺得比較簡(jiǎn)單,就當(dāng)作泛讀材料了解了解,認(rèn)識(shí)幾個(gè)新單詞或新表達(dá)方式也不錯(cuò)。如果大家覺得這些材料理解上有難度,不妨當(dāng)做挑戰(zhàn)自己的拔高訓(xùn)練,希望大家都有進(jìn)步^^

There are many known risk factors associated with suicide: those who take their own lives are statistically more likely to be white, male, and/or low-income. Surveys show that they are also more likely to have histories of depression, own fire arms and feel isolated. Many are divorced or have substance abuse problems. But a team of researchers found another risk factor that is less intuitive, even though it may be just as valid: living at a high altitude.

The team, lead by Dr. Barry Brenner from the University Hospitals Case Medical Center in Cleveland Ohio, analyzed 19 years worth of cause-of-death data from all 2,584 U.S. counties (between 1979 and 1998). In their study, published in High Altitude Medicine & Biology, they compared the 50 counties with the highest suicide rate to the 50 counties with the lowest, and found that county altitude was on average almost eight times higher in the areas with high suicide rates.

Even when the researchers controlled for five other suicide-related factors — two measures of income,race, age and population density of the county — the correlation was still strong. Wrote the scientists:

Prior reports of increased suicides in the U.S. Mountain Region (e.g., Colorado) have prompted speculation that the excess is owing to greater access to rearms, increased isolation, or reduced income. Even after controlling for these variables in our analysis, the positive correlation between altitude and suicide still exists, which suggests that the increased suicide rate in the regions with greatest altitude, such as the Mountain Region, may be owing to, at least in part, its altitude per se.

The authors note that there may be physiological reasons why high altitude may contribute to suicides; low barometric pressure in mountainous regions, for example, causes the body to become less efficient in transporting oxygen from the air, and these changes can affect brain functioning. In addition, they note, it's only suicides, and not other deaths that are positively associated with higher altitudes. While the results still need to be replicated, they at least suggest that achieving the "mountain high" may come at a dangerous price.

本篇文章開篇介紹了導(dǎo)致自殺的一般原因,如收入低,有抑郁癥病史,感到孤獨(dú)等,并由此引出一個(gè)新發(fā)現(xiàn)——自殺還與海拔有關(guān)。

接著,文章開始介紹這項(xiàng)研究的相關(guān)數(shù)據(jù)和過程,這其中還涉及到其他因素,如種族、年齡、密集程度等。

最后一段,文章從海拔對(duì)人生理的影響進(jìn)行剖析,說明海拔通過影響人的生理,進(jìn)而影響人的大腦功能,導(dǎo)致人們想不開而尋短見。

這類研究性文章我們關(guān)鍵是要先找到主題句(或主題段),一般都會(huì)出現(xiàn)在開篇或結(jié)尾處。另外這類文章通常的行文規(guī)律是研究發(fā)現(xiàn)——研究過程和對(duì)象介紹——研究補(bǔ)充內(nèi)容。大致瀏覽文章結(jié)構(gòu)和基本內(nèi)容后我們就可以根據(jù)題目進(jìn)行排查,比如主旨題,我們可以對(duì)照文中核心句或核心段落;態(tài)度題一般來說答案絕對(duì)不可能是極端類的態(tài)度,一般都是客觀,溫和型的。而細(xì)節(jié)題則要根據(jù)題目中透露的信息去相關(guān)段落查找。
