广州越秀托福学习班秋季冲刺托福100+

在找工作时，托福考试成绩比大学英语四六级成绩的含金量更高。此前网上有人把托福和四六级做了对比，虽然并不能保证精确，但也可以做一个参考，具体的对比情况如下：四级及格线相当于托福50分，六级及格线相当于托福60分；四级500分相当于托福70分，六级500分相当于托福80分。从上面的对比中可以看到，其实托福成绩的含金量要更高一些，大家如果能考出不错的托福成绩，在找工作的过程中也比别人更具竞争力。相对来说，托福成绩更能说明你真实的英语能力。学好了英语，你的就业面也会拓宽许多，不仅可以选择自己专业相关的职业，也能选择与英语相关的行业，而且，今天的许多行业中，如果你能同时具体专业知识和过硬的英语能力，肯定会有非常不错的发展前景。

托福阅读背景知识之厄尔尼诺

　　考生在备考托福考试的时候如果能多了解一些背景知识，那对考生的答题是十分有帮助的，今天托福老师就为考生分享下托福阅读背景知识之厄尔尼诺，希望对考生有帮助。

　　The research is published online in the journal Nature Geoscience(地球科学). El Nino is a periodic(周期的)warming in the eastern tropical Pacific that occurs along the coast of South America. Recently, scientists have noticed that El Nino warming is stronger in the Central Pacific rather than the Eastern Pacific, a phenomenon known as El Nino Modoki (Modoki is a Japanese term for "similar, but different").

　　Last year, the journal Nature published a paper that found climate change is behind this shift from El Nino to El Nino Modoki. While the findings of that paper are still being debated, this latest paper in Nature Geoscience presents evidence that El Nino Modoki drives a climate pattern known as the North Pacific Gyre Oscillation (NPGO).

　　"We've found that El Nino Modoki is responsible for changes in the NPGO,"said Emanuele Di Lorenzo, associate professor in the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. "The reason this is important is because the NPGO has significant effects on fish stocks(鱼类)and ocean nutrient distributions(海洋营养分布)in the Pacific, especially along the west coast of the United States."

　　The NPGO, first named two years ago by Di Lorenzo and colleagues in a paper in Geophysical Research Letters, explained for the first time long-term changes in ocean circulation of the North Pacific, which scientists now link to an increasing number of dramatic transitions in coastal marine(沿海海域)ecosystems.

　　"The ecosystems of the Pacific may very well become more sensitive to the NPGO in the future," said Di Lorenzo. "Our data show that this NPGO is definitively linked to El Nino Modoki, so as Modoki becomes more frequent in the central tropical Pacific, the NPGO will also intensify(增强)."
