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.

Psychology(心理学)tells us that many people hate to take risks. But it is good for us to take risks, especially when the risk is to achieve a desired(渴望的) result. In that way, we become stronger and braver.

Our human nature should be to take risks, but some people just sit and wish they didn’t have the fear to move on. This is because they failed a few times in their lives. Please step out and don’t let the past hold you back from living life to the fullest. Move forward and move on! In studying the psychology of taking risks, we find that human nature provides us with the desire to experiment and take chances.

Risk taking is a great advantage that allowed our ancestors(祖先) to become stronger and stronger day by day. By taking risks they fought off enemies and discovered new territories(领土). This attitude has become a part of our modern culture. Riding a roller coaster is a common risk taking activity. Even each person seems to enjoy the risk although they have the understanding that it is dangerous. This psychological and biological (生物学的) connection creates an interesting connection between what is unsafe and what humans enjoy.

Getting in a car each day is a risk. Getting out of bed is a risk, too. We need to take risks so that we can complete many things. Astronauts take risks when they get inside a rocket(火箭); however, the things they achieve are great. Businessmen take a risk when they buy parts of a company. However, without doing that, they could not make more money.

We need to take risks so that we can gain(获得) something. It is impossible to move forward in life, earn money, enjoy a relationship, play a sport, or do anything else without taking a risk. It is all part of the game. It’s one of the most important parts of life.

1.Some people don’t want to take risks, mainly because ___________.

   A. they are too lazy to move on

   B. they feel pleased with the present life

   C. they have failed several times before

   D. they show little interest in the strange world outside

2.What does the underlined part “This attitude” in Paragraph 3 mean?

   A. Taking risks                          B. Fighting off enemies

   C. Discovering new territories           D. Becoming stronger and stronger

3.What can we infer from the passage?

   A. Daily life is full of risks.

   B. The safest place has the greatest risk.

   C. People should take risks when they are young.

   D. We can always achieve our goals by taking risks.

4. Businessmen take a risk in order to __________.

   A. sell parts of a company

   B. complete many things

   C. make more money

   D. get inside a rocket

5.What would be the title for the passage?

   A. Taking risks is easier said than done    B. Risks taken by ancestors

   C. Live our life to the fullest              D. No risk, no gain.
