二、阅读理解
In Chinese, what word do you usually use to call your mother? It's "Mama", isn't it? And as you know, in America, kids call their mother "Mom" or "Mommy". In French, the word is "Maman", and in Arabic, it's "Ummi".
Have you noticed that these words for "mother" all have a sound close to "m"? Similarly, the words for "father" almost all have the sound "b" or "p". There are over 7,000 languages around the world. The words for other things are usually very different from one language to another. But why are the words for "mother" and "father" so similar?
The answer lies in how babies start to talk. The easiest sound a baby can make is "ah". A child can make this sound without the use of his tongue (舌头) or lips (嘴唇). Then, if he is going to change things a little bit, the easiest thing to do is to break up that sound by closing his lips for a while. The child, by this point, has long been doing this to suck (吸吮) milk. And so, the baby makes the sound "mah".
In fact, babies "speaking" in this way are just playing. Adults, however, don't think so. When a baby says "mah mah", it sounds as if he is calling someone. And the person is most likely to be his mother. The mother takes "mah" as meaning her. When speaking to her baby, she calls herself "mama". The word "mama" starts to mean "mother". This happens with human babies worldwide.
After babies begin making "m" by putting their lips together, they pick up the sound "bah" or "pah" in a similar way. When they make this sound, they are thought to be calling their second closest person: their father.
In this way, you call your mother "mama", and your father "baba". In fact, you have been doing this ever since you started to make sounds.
