Question

If I ask you to shut your eyes and gave you a piece of apple to eat, would you be able to tell me what it is just by tasting it? Of course, you could. Your tongue is covered with tiny “taste buds” which help you know what different foods taste like. Do you know that foods would taste different if you did not have a nose? This experiment shows how important your nose is when you taste things.

What You Need:

• a friend to help

• small pieces of any food like carrot, orange, banana

• small pieces of apple, raw(生的) potato, and onion

What You Do:

There are actually three different experiments. You and your friend should take turns to try them on each other.

Experiment 1:

Have your friend close her eyes and open her mouth.

Give her a piece of the food and ask her to taste it.

Then, ask her what she thinks it is. She will probably guess correctly.

Experiment 2:

While your friend has her eyes closed, give her a piece of the raw potato. At the same time, hold a piece of apple right under her nose. Ask her to eat the potato (but don’t call it by name) and tell you what she thinks it is. She will say it is a piece of apple!

Experiment 3: (for the brave)

Take a piece of raw onion. You don’t have to close your eyes this time. Squeeze your nose closed with your other hand so that no smells can get into your nose. Now take a nibble of the onion. Surprise! As long as you hold your nose, you will not be able to taste the onion.

The Science Secret

You already know the science secret. Your nose and your tongue work together to make food taste the way it does. Your tongue, however, can taste only certain flavors like salty, bitter, sour, and sweet. All of the other “tastes” are actually “smells,” and you need your nose to “taste” them. Oh, and you might use this science secret the next time you are told to eat something you don’t like the taste of. If you hold your nose while you eat it, you won’t “taste” it at all.

3.B

【解析】

試題分析：本文利用三個小實驗來闡述了一個科學奧秘，舌頭能品嘗酸甜苦辣，但是當你把你的鼻子堵住的時候，你卻什么也味道也品嘗不出來了。在你品嘗事物的時候鼻子起到了多么重要的作用。

1.主旨大意題。根據. All of the other “tastes” are actually “smells,” and you need your nose to “taste” them.         可知人們需要嗅覺來聞到不同種類的食物，故選C。

2.細節理解題。根據Squeeze your nose closed with your other hand so that no smells can get into your nose.用你的手輕輕的捏住鼻子不讓氣味進入你的鼻子，故選B。

3.標題歸納題。根據文章利用三個實驗來說明鼻子在品嘗事物時有多么的重要，故選B。
