有这样一本杂志,它经常是雅思、托福、SAT考试的科学类文章出题来源,同时也可以给你的雅思、托福、SAT写作积累素材,同时它又内容丰富又有趣,据说经常看的小伙伴可以拓展视野,更了解科学,这么神奇的杂志,到底是什么?想必一些同学已经猜到了,没错,它就是科学美国人——Scientific American。(以下简称SA)

 

今天节选几段让同学们感受一下。

蠢萌的电鳗

CATANIA REPLIES:lots of people are curious aboutwhy these eels don’t shock themselves— including me. No one seems to know the details, but I think Rogers is on the right track. It seems inevitable there are paths of very low resistance, along with areas of electrical insulation, within the animals (we do know the latter exists around their electrocytes—the biological batteries). But I can say this much: the eels are just barely protecting themselves. Sometimes an eel that has curled itself to amplify the electrical effect on its prey ends up activating its own fins with each high-voltage volley. So the experience is at least mildly shocking, even to the eel.

译文

大家都很好奇电鳗自身带电,但居然伤不到自己,Rogers无论作为吃瓜群众还是专业研究员,他的猜测或研究方向是正确的:电鳗自身带有“电阻”,用来保护自己不被电到。然而电鳗貌似并不清楚自己的这项特异功能,例如在对付prey的时候,自身的鱼鳍释放出的电压,恐怕连它自己都吓一跳。

知识点

on the right track表示步入正轨,走上正确的道路

end up doing 是用来表示结果,以…的结局而告终

例句:

As long as she keeps doing that, she’s on the right track.

只要能够坚持下去,她就做对了。

We've seen that Wilson's grand designs ultimately failed but he was on the right track for world peace.

我们已经看到,Wilson的宏伟规划最终失败了,但他是走在世界和平的正轨上。

We could all end up being friends.

我们最终可能成为朋友。

The result is that you could end up paying tax on the same income to two states.

结果是你最终可能要向两个州缴纳同一份收入的税款。


下面这篇文章,同学们可以自己读一读,尝试翻译一下,看能否理解文章意思。

枪击案致死率That adds up to 136,000 Americans harmed or killed annually by gun violence. Worse, the death side of this sad ledger is growing, according to the Centers for Disease Control and Prevention, in an upward trend that began in 2015. While mass shootings in Sutherland Springs, Tex., or Parkland, Fla., dominate headlines, people such as the St. Louis children, cut down singly or by twos or threes, make up the bulk of the victims. Guns are a clear and present danger in this country, where there are about 393 million civilian-owned firearms—more than enough to put one in the hands of every man, woman and child and amounting to the highest rate of gun ownership in the world by far.

知识点

ledger 本义是账簿

a collection of financial accounts这里指的是记录在案的 tragic record,枪击案致死的数字依然呈上升趋势。

dominate headlines是占据新闻头条,总会有一些人或事达到eye-catching的效果

例句:

Whether lauded, vilified or mocked, Trump continues to dominate headlines and consume an oversized portion of America's political oxygen.

无论是被世人称赞,诽谤抑或嘲笑,川普始终霸屏, 成为美国政治中街谈巷议的焦点。


除了提升词汇量、了解知识,阅读外刊最大的作用就是帮助同学们习惯英文字母的阅读,面对SAT长篇的文章依然能够集中注意力抓取信息。

外刊内容丰富,主题有趣,可读性相对要强,不过还请同学们记住贵在坚持,量变的积累才能实现质变。
