Unit 4.
2
A life beyond Earth?
3
A. Is there intelligent life on other planets besides Earth?
4
For years, scientists weren't sure.
5
Today, this is changing.
6
Seth Shostak and Alexandra Barnett are astronomers.
7
They believe intelligent life exists elsewhere in the universe.
8
They also think we will soon contact these beings.
9
B. Why do these astronomers think intelligent life exists on other planets?
10
The first reason is time.
11
Scientists believe the universe is about 12 billion years old.
12
According to Shostak and Barnett, this is too long a period for only one planet in the whole universe to develop intelligent life.
13
The second reason is size.
14
The universe is huge.
15
Tools such as the Hubble telescope have shown that there are at least 100 billion galaxies, says Shostak.
16
and our galaxy, the Milky Way, has at least 100 billion stars.
17
Some planets that circle these stars might be similar to Earth.
18
Looking for intelligent life.
19
See, until recently, it was difficult to search for signs of intelligent life in the universe,
20
but now powerful telescopes allow scientists to identify many more small planets in other solar systems.
21
If these planets are similar to Earth and are close enough to a star, they might have intelligent life.
22
Making contact D have beings from outer space already visited Earth?
23
Probably not, says Shostak.
24
The distance between planets is too great.
25
Despite this, intelligent beings might eventually contact us using other methods such as radio signals or flashes of light.
26
In fact, they could be trying to communicate with us now, but we may not have the right tools to receive their messages.
27
This is changing, however, says Shostak.
28
He predicts that we will make contact with other life forms in our universe within the next 20 years.

练习技巧

在通过观看视频进行英语学习时，您可以运用 shadowspeak 练习法来提升您的听说能力。视频的语速适中，您可以逐句模仿，注重发音的细节。这种练习有助于您 提高英语发音，并使您在雅思口语练习时更有信心。

建议您在观看视频时，先听一遍完整的句子，然后慢慢重复。在重复的过程中，注意语调和节奏，使您的发音更加自然流畅。学习如何用不同的语气表达疑问和论点，将有助于您更好地理解交流的内容。

此外，您还可以使用 shadowing site 提供的资源，寻找类似主题的视频，加强您的学习效果。通过不断的练习，不仅能增强词汇量，还能更好地理解宇宙科学的相关信息。

视频中的语法

说话人最常用的结构，并附上视频中的原话：

结构视频中的用法
用 “might / may” 表可能 might/may + 动词 — 有可能但不确定的事might be · might have · might eventually contact
现在进行时 am/is/are + -ing — 此刻或近期正在发生的事is changing
“will” 表将来 will + 动词 — 决定、承诺或预测will soon contact · will make

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。
