正在创建课程...
1
This worm has won more Nobel Prizes than anyone else.
2
Meet C elegans, a worm so small it could pass through the eye of a needle.
3
Thanks to its transparent body and speedy life cycle, scientists were able to track every one of its 959 cells from cradle to grave,
4
building the first complete blueprint of a living organism.
5
They even mapped all of its neurons and their connections, creating the first connectome, kickstarting the science of brain mapping and unlocking powerful genetic tools.
6
C elegans was also the first animal where green fluorescent protein was used to track gene activity.
7
When certain genes were switched on, the worms would literally light up.
8
It even helped us in switching off specific genes, which became a key tool in genetics and drug development.
9
By helping us to find the genes that tell cells when to grow, divide or die, it brought us closer to understanding diseases like cancer.
10
This worm even went to space, helping scientists explore how microgravity affects muscles, aging and DNA repair.
11
If a tiny worm can help win four Nobel Prizes, surely the rest of us can aim for at least one.

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。
