Now, the study of biology is responsible for some of the most profound insights that humans have about the world around them.
2
So, take a look at these four panoramas.
3
In the upper left, you see some bacteria this happened to be, coli, you obviously see a butterfly, a flower, a dolphin.

7
If you see that at the outer space, just looks these different forms and structures.
8
You have no idea that they were all related to one another.
9
So one of the most profound things that biology told us is
10
that all life on Earth is exceptionally related to one another.

So one of the most profound things that biology told us is
14
that all life on Earth is exceptionally related to one another.
15
So, for example, all of these life forms rely on DNA and RNA for storing, transmitting and using their genetic and inherited information.
16
They are all based on cells.
17
Cells are the fundamental building blocks of all life.
18
All of these organisms consist of cells, and the cells essentially have the same chemicals inside of them.

22
All of these organisms consist of cells, and the cells essentially have the same chemicals inside of them.
23
carbon, hydrogen, oxygen and nitrogen, and the whole bunch of other stuff in much smaller amount.
24
All these organisms conducted metabolism, in other words, chemical reactions that use and convert energy from one form to another.
25
And the basic chemistry is all very similar to one another.
26
The type of molecule is used very similarly to one another.
27
carbon, hydrogen, oxygen and nitrogen, and the whole bunch of other stuff and much smaller amount.

- 词尾辅音 — 要读清楚，后面不要加元音: profound /pɹəˈfaʊnd/, inherit /ɪnˈhɛɹɪt/, transmit /tɹænsˈmɪt/, consist /kənˈsɪst/
- /æ/ — 嘴张大，不要读成 /e/: bacterium /bækˈtɪəɹ.ɪəm/, panorama /ˌpæn.əˈɹæm.ə/, transmit /tɹænsˈmɪt/, metabolism /məˈtæb.əˌlɪz.əm/
如何用这段视频练习
- 先完整听一遍视频，不要开口，记下不认识的单词。
- 用正常速度逐句跟读，每句重复到你的节奏与说话人一致为止。
- 录下自己的声音并与原声对比，特别注意 organism, bacterium, coli 这类单词。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
