Lesson 23 Television Day:Right or left?

第23课 电视日:是右还是左?
Which of your two hands do you use most?

你最常用哪只手?
Very few of us can use both of our hands equally well.

我们当中很少有人能双手都运用自如
Most of us are right-handed.

多数人惯用右手
Only about five people out of a hundred are left-handed.

每100人中大约只有5人是左撇子

but in about two years they usually prefer to use their right hands.

但过2年他们通常用右手了
Scientists don't know why this happens.

科学家不知道这是怎么形成的
They used to think that that we inherited this tendency from our animal ancestors

过去他们常认为我们从我们的动物祖先那儿继承了这一习性
but this may not be true.

但这不一定对

猴子是我们在动物世界中关系最近的动物

科学家们发现
monkeys prefer to use one of their hands more than the other

猴子喜欢用某只手多于另一只手

但这可是两只手中的任何一只
There are as many right-handed monkeys as there are left-handed ones.

用右手的猴子与用左手的猴子一样多
Next time you visit the zoo,watch the monkeys carefully.

下次你去动物园时,仔细观察一下猴子
You'll see that some of them will prefer to swing from their right hands

你会发现有些猴子用右手荡秋千
and others will use their left hands.

而另一些猴子则用左手
But most human beings use their right hands better.

但大多数人用右手更为灵活
and this makes life difficult for those who prefer to use their left hands.

这就使得用左手的人生活较困难些
We live in a right-handed world.

我们生活在一个惯用右手的世界
