【题目】If I were to ask you to close your eyes and I 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 (舌头) helps you know what different foods taste like. Do you know that foods would taste different if you did not have a nose?

What You Need

a friend to help

small pieces of any food like carrot, orange, banana—whatever you have

small pieces of apples, raw (uncooked) potato and (if you are brave) onion (洋葱)

What You Do

There are actually three different experiments. You and your friend should take turns trying 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 raw potato. At the same time, hold a piece of apple right under her nose. Ask her to eat the potato and tell you what she thinks it is. She will say it is a piece of apple! You can even do it the other way around, and she will think she is eating a potato, or, perhaps, she won’t be able to name what she is eating.

Experiment 3: (for the brave)

Take a piece of raw onion. You don’t have to close your eyes this time. Press your nose closed with your other hand so that no smells can get into your nose. Now eat a small piece 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, you might use this science secret the next time you are forced 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.

1According to this article, what could a person know about food?

A. People hold their noses to eat onions.

B. If you close your eyes, food will taste better.

C. People need a sense of smell to taste some food.

D. If you can smell potatoes, you will taste apples.

2What is the most probable reason Experiment 3 is called “for the brave”?

A. You have to eat a raw onion. B. You keep your eyes open.

C. You have to hold your nose. D. You do the experiment alone.

3What can we learn from the passage?

A. Knowledge comes from personal experience.

B. Team work helps us to find out science secrets.

C. We should have courage while doing experiments.

D. We can’t draw a conclusion simply from the feeling.

4What’s the passage mainly about?

A. Why different foods can smell the same.

B. How smell influences the way food tastes.

C. Why some things smell better than others.

D. How smell changes the way we see things.

【题目】Look!People are gathering to get water from a huge well in the village of Natwarghad in the western Indian state of Gujarat!61.Because of the large population on the earth,the world is ________hungry,it is ______be thirsty for water now.The world’s population has reached 7 billion.And it could possible grow to 15 billion by the year 2100.

The sea seems to have the best answer.The is very big.Look at the map of the world,there is more sea than land.It covers three quarters of the earth.All that needs to be done is to get the salt out of the sea water.Scientists are trying to find a cheaper way of doing it.So you see,64如果我们可以找出解决方法,我们就不会有干涸(dry up)的危险。
