冒犯了,Kevin,I beg to differ.

“You should have just something to keep in mind”不是地道英语（idiomatic English），不信可以去google一下。不能这么解释。

“Just something to keep in min ...

能否推荐点合适的阅读材料？谢谢

June 29, 2007: 60-Second Science
Each Human Baby Has Its Own Unique Intestinal Microbe Collection

Top down思维知识提示：

Have an obsessive interest in what comes out of their babies’ bottoms
Diaper diving
Colonize the human gut
GI tracts   （gastrointestinal tract）
Help digest food
Devoid of bacterial inhabitants
A cavalcade of microbes set up shop, establishing a vibrant intestinal community
Outnumbered
With established species disappearing and new ones…
Each harbored a dynamic but unique intestinal fauna（见注）
A set of fraternal twins had the most similar bugs   （听过flu bug吗？类似用法）
Stick around
Formula versus breast milk
Mining diapers

注：Intestinal fauna用的人很少，这个用法是否正确我不知道，必须问一下科学家，但可以肯定的是多数人说intestinal flora (google里有50万个citations). 不管是Intestinal fauna还是intestinal flora, 指的都是肠道里的bacteria细菌。Fauna是动物，flora是植物，bacteria人们一直以为是植物的祖先，但现在也有人猜测它是动物的祖先，所以你说它是动物还是植物？好在托福不深入探讨科学问题，咱们只需把这几个托福词汇背起来就行了。


又，注意到前后呼应的diaper幽默吗？

Good question! But it is hard to give you a good answer. If you are not pressed for time to take the TOEFL, try to read a wide variety of materials (and by the way, chuck your Chinese newspapers if you are still reading them).  If you only have a few months to prepare for TOEFL, National Geographic, Discovery, Nature, NPR all have TOEFL-like texts you can read. If you only have a few weeks to prepare for TOEFL, forget about this question and go enjoy yourself.  :loveliness:   There is nothing you can do to have an impact on your reading score; not even the old TOEFL trick of memorizing 10,000 words will save you!

Thx. I am not sure if I will take the TOFEL. I just want to enjoy my time  improving my English.

先暂停一段时间:(
希望大家坚持。。。。。:)
我会注意top down 思维的;)

大家觉得今天的60秒难度怎么样？
我听了一下，觉得没有能力抄写啊，对我来说就是天书，看了zhenzhen_163 的分析，里面专业术语很多，不知道IBT是否也是这样的难度？
直接没信心了。。。。SOS。。。。

好

不要气馁。Karen 的diction (enunciation)不如Steve清楚，如果换了Steve来读，咱们可能就能多懂一些。托福的录音都较慢、较清楚，我在#635楼已说过，去看看，你会感觉好一些。:)

Many people have asked me how many times I have to listen to the recording in order to transcribe the entire text. This, to me, is akin to asking how good my memory skills are. I am not a professional stenographer; neither do I have perfect memory. Therefore, it always takes me many times before I can write down every single detail.

Please read my posts #635, #698 and #724. Risking repeating myself, I think we should all be paying more attention to top down processing and not be worrying about how many times it takes us to figure out the individual words based on sound alone.

New parents can act pretty strangely, for example, they often have an obsessive interest in what comes out of their babies’ bottoms. Now researchers at Stanford University join them in a diaper diving to explore when and how bacteria colonize the human gut. Adults harbor complex microbial ecosystems within their GI tracts. These bacteria help digest food and contribute to a healthy immune system. But when a baby is born, its intestine is devoid of bacteria inhabitants. Within days, however, a cavalcade of microbes set up shop, establishing a vibrant intestinal community whose residents soon are members of the baby’s own cells. The researchers found that the early months were chaotic, with established species disappearing and new ones taking their place. But by the time the babies were 12-month old, each harbored a dynamic but unique collection of intestinal fauna. A set of fraternal twins had the most similar bugs, which suggested the (删) genetics may have something to do with which bacteria take (stick) around. Next They'll have a look at how formula versus breast milk affects babies’ intestinal ecosystem. With so many questions left to explore, the researchers will no doubt be mining diapers for some time to come.
