A mouse looked through a hole in the wall to see the farmer and his wife opening a package. What food might it contain? He was astonished to discover that it was a mouse trap!
Running to the farmyard, the mouse shouted, warning, “There is a mouse trap in the house; there is a mouse trap in the house.” The chicken with her head high, said, “Shut up, Little Ugly. This is a great concern to you, but it has nothing to do with me; I cannot be bothered by it.”
The mouse turned to the pig and told him, “There is a mouse trap in the house.” “I am so very sorry, Mr. Mouse,” said the pig, “but there is nothing I can do about it but pray; you are always in my prayers.”
The mouse turned to the cow, who said, “A mouse trap; am I in great danger, huh?”
So the mouse had to face the farmer’s mouse trap alone.
That very night a sound was heard through the house, like the sound of a mouse trap catching its prey. The farmer’s wife rushed to see what was caught. In the darkness, she did not see that it was a poisonous snake whose tail the trap had caught. The snake bit the farmer’s wife. The farmer rushed her to the hospital.
She returned home with a fever. It is said that drinking fresh chicken soup will help treat fever, so the farmer took his sharp knife to the farmyard for the soup’s main ingredient. His wife’s sickness continued so that friends and neighbors came to sit with her around the clock. To feed them, the farmer killed the pig. The farmer’s wife did not get well, in fact, she died, and so many people came for her funeral. The farmer had the cow killed to provide meat for all of them to eat.
So next time someone is facing a problem, don’t say that has nothing to do with you.

We’ve heard about radiation from the damaged nuclear reactors in Japan reaching American shores. Experts say so far there is no reason to worry, and point out that we meet radiation every day. Where and how? NPR’s Renee Montagne posed that question to Peter Caracappa, a radiation safety officer and professor of nuclear engineering.
MONTAGNE: How many things emit radiation?
Dr CARACAPPA: Well, radiation and radioactive material is a part of nature. So everything that’s living has some amount of radiation coming from it—a very small amout. Plus there’s radiation in the ground and the air.
So the extremes are uranium in the soil to bananas?
Yes.
By the way, why do bananas have radiation?
Bananas have a lot of potassium(钾). And a small amount of potassium naturally is called potassium 40, which is radioactive
What’s the difference between radiation that’s harmful and not harmful?
Well, the term radiation can apply to a lot of different things. But the harmful radiation is ionizing(离子)radiation. It has enough energy that it can make chemical changes in material. We could get ionizing radiation from an X-ray, for example. It’s the kind of radiation that causes cancer.
The broader definition of radiation includes a lot of things that we call non-ionizing radiation. That includes everything like radio waves and visible light and your microwave.
So what then is the largest contributor of ionizing radiation?
For the natural sources of ionizing radiation, actually the biggest chunk of that tends to come from radon(氡), which is a radioactive material that is present in the air. It can become a concern when it builds up in low-lying areas of homes like basements.
Would it be fair to say that most people do not need to worry about the danger of being exposed to radiation?
I would say that the everyday exposure to radioation that we meet contributes an extremely tiny risk to our life or to our health compared to all of the other risks that we meet in our day-to-day life.

|
B．whether it changes chemical in materials. |

C．whether it has energy to change materials |
|
D．whether it is visible in life |

If you are asked to name some national emblems of China, the dragon will probably be one of the famous images that pop into your head. We Chinese often consider ourselves "the descendants（后代）of the dragon." It is not unfamiliar to you that your parents hope that you "may become the dragon".
As a mythical（神秘的）creature, the dragon is deeply rooted in Chinese culture. Traditionally, dragons are considered to govern rainfall. They have the power to decide where and when the rain falls. In addition, the dragon is a symbol of imperial （帝王的）power. The emperors thought they were real dragons and the sons of the heaven.
But the creature is regarded differently in Western countries. In the Bible, dragons represent the devil（恶人）. Western people usually see dragons as cold-blooded reptiles（爬虫）, like snakes and cruel killers. In their eyes, dragons are also dishonest.
Dragons in Western literature are presented as monsters（怪物）. It is a common tale for a mediaeval knight（中世纪的骑士） to kill a dragon and save a princess and her country from its evil. Even the popular boy wizard Harry Potter has to battle against a dragon.
However, dragons are not all bad in the West. "Puff the Magic Dragon" is a well-known song. The lyrics(歌词) tell a bitter-sweet story of the dragon Puff and his playmate Jackie Paper, a little boy. When Jackie grows up, he loses interest in the imaginary adventures of childhood and leaves Puff upset. Puff represents the innocence of a child's imagination, which is very positive for a dragon.
1.The underlined word” emblems” in the first paragraph means “_______”.
|
A．symbols |
B．names |
C．places |
D．parks |
2.What is a dragon presented as according to Western literature?
A wizard B. A mediaeval knight C. A princess D. A monster
3.The writer gave the example of “ Puff the Magic Dragon” to show_____.
|
A．dragons can represent the innocence of child’s imagination |
|
B．children don’t like to play with dragons |
|
C．dragons are not all bad in the West |
|
D．not all people in the West like dragons |
I am always eager to do experiments, especially chemistry ones. It's _26_ to work with test tubes and beakers（烧杯） , even though sometimes my efforts end in__27___. Experiments were fun for me __28 a recent accident.
The 29 happened when I was heating a big test tube with an alcohol burner（酒精灯） , chatting to my partner while waiting for__30____ changes. All of a sudden, the tube cracked. Even though I jumped from my seat when I heard the crack, the hair on my forehead was __31____ as I was leaning too close to the test tube.
__32___ I had no time to be sad about my hair: the liquid in the test tube poured onto the table and caught fire. I'd never 33 _ anything so bad! My___34___went blank （空白）for a moment. Then I quickly covered the fire with a damp cloth to__35____.
The teacher told me that the test tube broke in half at the bottom because we didn't dry it properly before __36___ it.
We calmed down and did the experiment, again. But our hearts were still __37____ rapidly even after we walked out of the lab.
But my bad __38___ didn't end there! Since all __39 was focused on the flames while we were in the lab, I didn't see the liquid falling onto my trousers.
During the following class, I felt a __40___ in my leg. Soon it became more and more painful and I touched the area with my fingers, _41_ to make things better. But to my great 42___ , the material of my trousers turned into powder! “Vitrio（硫酸）! ! !”The terrible word came into my mind. I rushed out right away to wash and examine my poor skin. _43_ , it was not a serious injury.
After changing my __44____I sat down and told myself: danger is no joke! It's very important to have a serious___45___ in chemistry class. Doing scientific experiments as a learner is no laughing matter.
