What would happen if you tried to blow a soap bubble in freezing weather? Would it freeze solid(固體) and fall to the ground? Would you have to hit it to break it? These questions happened to me on a cold winter day. It was too cold to play in the snow, but it was a perfect time to experiment with blowing frozen bubbles.
To blow frozen bubbles, I used dishwashing soap and a drop of glycerin(甘油) to make it even better. I chose a place out of the wind, and blew bubbles the same way I always do. I watched to see what would happen. Here’s what I learned.
If the temperature is low enough, the skin of the bubbles frosts over (結(jié)霜), becoming cloudy instead of clear. And what about those rainbow swirls(旋轉(zhuǎn)) you see in soap bubbles? The rainbow colors stay even when the bubbles frost, but they don’t swirl anymore. The bubbles still stay in the air. They don’t fall to the ground any faster than they would on a warm summer day.
When these frozen bubbles break, they don’t turn into small water drops as summer bubbles do. They turn into flashing rainbow confetti(碎屑) and move slowly to the ground. Sometimes a frozen bubble will roll across the snow without breaking. If nothing disturbs the bubble, it may stay there for a long time. Sometimes I could catch a bubble and hold it until the heat of my hand made it pop.
I learned another thing about blowing frozen bubbles. It’s so interesting that I want to try it again next year.
小題1:It is the perfect time to blow frozen bubbles on a ___________day.
A.cold winterB.warm springC.hot summerD.sunny autumn
小題2:When the frozen bubbles break, _________.
A.they make a big soundB.they turn into small drops

What do you think is the most important invention in the world? The TV? The printer? The telephone? Or the computer? A report shows that they are not the only important inventions. Here are three other important inventions.
One of the simplest inventions is the toilet. Before toilets, people poured or dumped waste into rivers from people’s houses. Illnesses were common in big cities, and it was often difficult to find clean drinking water.
Animal food is another important invention. Before the invention, most animals were killed every autumn because there was not enough food for them in winter. After hay(干草) became a kind of common animal food, animals could live through the long winter.
The third great invention is glasses. Glasses help people read, write and do “close work” after the age of 45. Without glasses, the word would be difficult for the people above 45.

I live on the twelfth floor of a building. One afternoon I was coming home from a friend's house. It was just after four o'clock. I got quickly into the lift and pressed Button (按鈕) 12.
The lift started to go up, but very slowly. And then, halfway up, it suddenly stopped between two floors. I couldn't understand it. I pressed all the buttons from 1 to 14. I called for help very loudly. But nobody answered.
Then suddenly the lights went out, and I was alone in the dark. I started to cry and beat the walls of the lift. I cried and cried until I had no voice left. Then, I felt hopeless, and pressed all the buttons with my open hands. And all at the same time, there was a bell far away. It rang and rang. It was the fire alarm (火災(zāi)警報). I thought the whole building was on fire. I said to God quietly, "Just get me out of here. I'll never be bad again."
Just then, I realized the lift was moving very slowly. On the ground floor it stopped, and the doors opened. A man was standing there. "How long have you been in the lift? It is good that you pressed the alarm bell. But haven't you learned to read at your school?" He pointed at a small piece of paper on the wall beside the lift. It said:
"Attention: This lift will be stopped for repairs between 4pm and 5 pm on Thursday March 13."
