Unit 7.
2
B. Mystery of the Terrible Hand.
3
A whose hand is this?
4
For 50 years, paleontologists searched for an answer to this question.
5
In 1965, paleontologists discovered a pair of giant arms in Umnagobi, an area in Mongolia's Gobi Desert.
6
The length of each arm was 2.4 metres.
7
The claws were over 25 centimetres long.
8
Palaeontologists called the animal Dinochirus, meaning terrible hand.
9
What did the body of this animal look like?
10
Palaeontologists had different opinions, but no one knew for sure.
11
They examined the area many times, but found only a few other fossils of the dinosaur.
12
So scientists used Dinochirus's arms to estimate its body size.
13
Recently, however, a team of palaeontologists dug up many more bones that tell us a lot about Dinochiris' appearance.
14
C. Dinochiris was one of the Ornithomimosaurs, a type of dinosaur that looked like a modern-day ostrich.
15
It was 11 metres long and weighed 6,000 kilograms, almost as big as a T-Rex.
16
Dinochirus was clearly very big, but it was not a predator.
17
It couldn't move quickly and in fact it had no teeth.
18
Its head looked similar to a horse's head and it had a long tail, perhaps with feathers at the end.
19
Most Surprisingly, though, Dynachyrus had a rounded hump or sail on its back.
20
This dinosaur probably ate fish, small animals and soft plants.
21
Why did it need such long limbs?
22
Paleontologists now believe that its long arms were used simply to dig for food or to pull down high branches.
23
D. So the mystery of the terrible hand, it seems, has been solved.
24
It is amazing to see what Dinokyrus actually looked like and to find out more about this giant dinosaur.
25
But Dala Zelenitsky from the University of Calgary says it's also sad in a way.
26
Even scientists like a bit of mystery and that mystery is now gone.

练习技巧
在进行英语口语练习时，"shadow speech"是一种非常有效的方法。当你观看这段视频时，试着跟随说话者的语速和语调进行练习。以下是一些具体的建议：
- 反复观看：首先，观看视频一次，理解内容后再进行逐句模仿。
- 慢速开始：如果你觉得视频速度较快，可以调整播放速度，先以慢速观看，确保能够跟上。
- 暂停与复述：在重要的短语出现时，暂停视频并尝试复述这些短语，确保发音准确。
- 专注语调：注意说话者的语气变化，特别是在描述Dinochirus外观和习性时，试着用相似的情感表达自己。
- 多角度练习：可以和朋友一起练习，把视频中的内容用不同的方式进行复述，增强记忆。
通过上述练习，你将能够显著提高英语口语能力，尤其是在描述复杂概念时的流利度，让你的“看YouTube学英语”之旅更加丰富多彩。
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。
