PTE考生目前最大的问题之一就是练习题缺乏。除了有限的基本官方书（PLUS，Testbuilder, OG）之外
就没有题了。很多英语基础不是很扎实的同学很难找到练习材料。悉尼文波雅思PTE培训学校专门为澳洲，尤其是悉尼、墨尔本的PTE考生准备了适合PTE听力阅读练习的科学60秒。各位PTE同学可以练习PTE听力中的summarise spoken text和PTE口语中的retell lecture，PTE听力口语-科学60秒-Frosty Moss练习记笔记技巧和复述。废话少说，下面开始：

If you’re serious about fitness, you know the importance of training your muscles and your brain.
Without the right prep,you won’t have the physicalor mental endurance to finish,whether it’s a five–kor an Ironman.
But it turns out that it may be just as important to train your gut—or suffer inflammatory consequences.
So says a study in the International Journal of Sports Medicine.
Researchers sampled the blood of 17 runners before and after a 24-hour ultramarathon—whererunners covered anywhere from 75 to 130 miles on foot.
During the race,their guts got leaky—due to a lack of blood flow to the intestines,and the physical trauma from so many jarring miles.
Gut bacteria escaped into the blood,where some released toxins.
The runners’ bodies then responded by launching an immune response,and inflammation set in.
Some runners actually had blood profiles identical to those of patients admitted to the hospital with blood poisoning, or sepsis.
But the most well–trained competitors avoided the problem.
Their bodies launched a counter attack,unleashing anti–inflammatory compounds to tamp downtheir bodies’immune overreaction.
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,even if they’re not ultra worthy.
As has long been said: slow and steady wins the race.
