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】

试题分析：本文利用三个小实验来阐述了一个科学奥秘，舌头能品尝酸甜苦辣，但是当你把你的鼻子堵住的时候，你却什么也味道也品尝不出来了。在你品尝事物的时候鼻子起到了多么重要的作用。

1.主旨大意题。根据. All of the other “tastes” are actually “smells,” and you need your nose to “taste” them.         可知人们需要嗅觉来闻到不同种类的食物，故选C。

2.细节理解题。根据Squeeze your nose closed with your other hand so that no smells can get into your nose.用你的手轻轻的捏住鼻子不让气味进入你的鼻子，故选B。

3.标题归纳题。根据文章利用三个实验来说明鼻子在品尝事物时有多么的重要，故选B。
