If the temperature rises by 5 degrees tomorrow, you will probably take off just one coat. But such a change in the average world temperature would be a serious problem. Many animals and plants would not be able to deal with these changes, and would die.

The UNEP(联合国环境规划署) released(发布)the Report 2012 on November 21, 2012. It says that if we don’t take action now, the world temperature will have risen by 3 to 5 degrees by the end of this century.

A large rise in temperatures could be terrible for us and for many other living things on Earth. Sea levels will rise because higher temperatures will cause melting ice flow into the sea.Large coastal (沿海的) cities in countries such as the Netherlands and Bangladesh could be flooded.

Some plants such as corn and sugarcane (甘蔗) will not grow well in higher temperatures. Some countries, such as Brazil and parts of Africa, will not have enough food. The change may cause less rain and even make some places very dry.

On November 26, people from around 200 nations and regions gathered again in Doha (多哈) for the annual UN climate talks.“Climate change is coming to all human beings and effective actions need to be taken to deal with it.”president of the conference said at the opening ceremony.  

1.What will you probably do if the temperature rises by 5 degrees tomorrow?

2.When was the Report 2012 released by the UNEP?

3.Why will sea level rise?

4.Where did they attend the annual UN climate talks?

5.As a student, what action will you take to deal with the rising temperatures?(请自拟一句话)

What would happen if you tried to blow a soap bubble in freezing weather? Would it freeze solid(固体) 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 (结霜), becoming cloudy instead of clear. And what about those rainbow swirls(旋转) 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.
【小题1】It is the perfect time to blow frozen bubbles on a ___________day.

A.cold winterB.warm springC.hot summerD.sunny autumn
【小题2】When the frozen bubbles break, _________.
A.they make a big soundB.they turn into small drops
C.they fall to the ground like rain D.they become rainbow confetti
【小题3】The purpose of the passage is _______.
A.to learn how to do a science experiment
B.to show the experiment of blowing frozen bubbles
C.to discover games that are fun to play in the snow
D.to invent a new kind of soap that makes stronger bubbles
