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.

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

小題3:What’s the best title of the passage?

A．Your Eyes Knows	B．Your Nose Knows
C．Your Mouth Knows	D．Your Tongue Knows

Answer 1

小題1:C
小題2:B
小題3:B

試題分析：本文通過三個實驗說明鼻子的重要性，只有鼻子與舌頭一塊工作才能嘗出味道。
小題1:C 細(xì)節(jié)理解題。根據(jù)第一段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.你知道如果沒有鼻子食物嘗起來還會不同嗎，這個試驗證明當(dāng)你嘗東西時鼻子的是重要的。所以選C項。
小題2:B 細(xì)節(jié)理解題。根據(jù)倒數(shù)第二段提到Squeeze your nose closed with your other hand so that no smells can get into your nose捂住你的鼻子，為的不讓氣味進(jìn)入你的鼻子，Now take a nibble of the onion. Surprise! As long as you hold your nose, you will not be able to taste the onion.現(xiàn)在嘗嘗洋蔥，令人吃驚的是，只要捂住你的鼻子，你就嘗不出洋蔥的味道，可見這個試驗是需要勇氣來吃洋蔥的，所以選B項。
小題3:B 主旨大意。本文通過三個實驗來證明Your nose and your tongue work together to make food taste the way it does.你的鼻子和舌頭一塊作用才能吃出食物的味道。再根據(jù)第一段This experiment shows how important your nose is when you taste things.，說明鼻子的重要性，所以選B項。
