ESO, translated by — In child development,
3
one of the most important milestones is a concept called object permanence.
4
This is the understanding that objects continue to exist even when they cannot be seen, heard, or touched.
5
According to the psychologist Jean Piaget, infants usually develop this skill during the first two years of life.
6
For a very young baby, the world is essentially out of sight, out of mind.
7
If you show a four-month-old a colorful toy and then cover it with a blanket, the baby will act as if the toy has simply vanished.
8
They won't try to lift the blanket because, to them, the toy no longer exists.
9
However, as the child grows, they begin to maintain a mental image of the object.
10
By the age of eight or nine months, if you hide that same toy, the baby will reach out and move the blanket to find it.
11
This shows they understand that the toy is still there even though it is hidden.
12
Developing object permanence is a crucial step
13
because it allows children to move on to more complex tasks like symbolic play and language development.

17
Let's take a look at plate tectonics.
18
For a long time, scientists noticed that continents, like South America and Africa, seem to fit together, like pieces of a jigsaw puzzle.
19
In the early 20th century, the theory of continental drift was proposed.
20
It suggested that millions of years ago, all land was joined in a single supercontinent called Pangaea.
21
Over time, this landmass broke apart and the continents drifted away.
22
But how do continents move?
23
The Earth's outer shell is not one solid piece.
24
It is broken into sections called tectonic plates.
25
These plates float on a layer of hot, semi-liquid rock deep inside the earth.
26
As plates move, they interact.
27
At divergent boundaries, plates pull apart and molten rock rises to create new crust.
28
At convergent boundaries, plates collide.
29
This pressure pushes the land up to form mountain ranges like the Himalayas.
30
these movements explains why we have earthquakes and volcanoes.
31
Thank you.

Thank you.

Thank you.

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。
