备考托福的同学们都知道，托托福听力是重头戏。在托福考试中有三项都考到了托福听力。所以托福听力的重要性可想而知。所以托福听力的备考刻不容缓，而背景知识的选择这也是托福听力中的一个重要方面。下面前程百利小编为大家介绍的是SSS为什么是备考托福听力背景知识的首选?小编以最新来自sss的文章为例为大家介绍。
例子：
Even four hours of intense activity may be enough to let bacteria(细菌) escape from the gut into the blood, setting off a chain of inflammation(炎症). 【摆事实、中心思想】
If you're serious about fitness(健康), you know the importance of training your muscles and your brain. Without the right prep(准备), you won't have the physical or mental endurance to finish, whether it's a five-k or an Ironman. But it turns out that it may be just as important to train your gut—or suffer inflammatory(炎症的) consequences. 【详细介绍】
Researchers sampled the blood of 17 runners before and after a 24-hour ultramarathon(马拉松赛跑)—where runners covered anywhere from 75 to 130 miles on foot. During the race, their guts(内脏) got leaky(有漏洞的)—due to a lack of blood flow to the intestines(肠), and the physical trauma (物理创伤)from so many jarring(不和谐) miles. Gut bacteria (肠道细菌)escaped into the blood, where some released toxins(毒素). The runners' bodies then responded by launching an immune response(免疫反应), and inflammation set in.
Some runners actually had blood profiles(文件)identical to those of patients admitted to the hospital with blood poisoning, or sepsis(败血症).【做研究，验证事实】
But the most well-trained competitors avoided the problem. Their bodies launched a counterattack(反击), unleashing (释放)anti-inflammatory(抗炎) compounds to tamp (夯实)down their bodies' immune overreaction(过度反应).【解决方案】
The authors say just four hours of activity is extreme enough to kick off this chain of inflammation. Suggesting it's key to gradually build up to new personal bests(个人的), even if they're not ultra (极端的)worthy. As has long been said: slow and steady wins the race.【总结】
总结：
1.本篇文章中有很多的专业词汇。比如，physical trauma (物理创伤)toxins(毒素)，这些词汇和短语学科性比较强，这样就符合ETS的出题思路，托福听力就是考察学生对学科的熟悉程度。就算是到了国外也可以轻松的听懂老师上课要讲的东西。
2.本文的逻辑。首段先总结全文，这就与托福听力中的第一题主旨题相符合。接着用研究证明事实或者用例子证明事实，阐述事实。而托福听力中也是由教授提出主题然后讨论，也是通过教授自己的讨论和举例子，陈述事实。
3.本文的知识。本篇文章可以属于生物学科中，而对于托福听力考试来说，生物类是一个很重要的学科，几乎每次必考。而sss上提供的都是最新科技类文章所以跟托福听力是不谋而合。
所以托福听力的背景知识积累的首选就是SSS-科学人60秒。好了。以上就是前程百利小编为大家总结的内容，希望对大家有所帮助。最后，小编预祝大家在托福考试中取得好成绩。
