Things similar continuously happened in Haiti and Chile．Thousands of people were
buried in the earthquake and lost their fives．What if we could have warned them? People are always trying hard to find a way of preventing building collapsing(坍塌)．Better materials and technology help，but are not a solution．Just like humans，a building has its own life circle from “birth” to “death”．If we know when a building is going to collapse，we can repair it in advance or get out before it falls．
Now, scientists at the University of Illinois ha、，e developed a material that turns red before it breaks．The invention could be used in things like climbing ropes，or bridge supports．The secret behind the color-changing material is a type of molecule(分子)．A molecule is a group of atoms held together by chemical bonds(化学键)．Imagine you and your friends standing in a circle，holding hands．Each person stands for one atom，your hands represent the bonds，and the entire circle represents a molecule．If one person lets go of his or her hands，the molecule changes color．The research team put the molecule into a soft material．When the researchers stretched(拉长) the material：it turned bright red a few seconds before it broke into two pieces．
When they repeatedly stretched and relaxed the material，without breaking it，it only turned a little red．
The major problem is，light can get rid of the red color．When the team shone a bright light on the molecule，the broken bond was fixed，and the color disappeared．If bright fight keeps the red color from appearing，the material’s warning system will be useless．Scientists still have a lot of work to do before the color-changing molecule can be used outside the lab．
49.The passage is mainly about______________
A．a way of preventing building from breaking down

51.The color-changing molecule can___________
A．make building materials much stronger
B．help building materials get stretched if necessary
C．prevent the earthquake from killing people
D．remind people to leave buildings before they fall
52．The warning system is based on the fact that____________
A．red color won’t show up when it meets bright fight
B．a material with a certain type of molecule Can turn red when setched
C．a building has its own life circle of “birth”to“death”
D．the broken bond will fix itself when a molecule meets bright fight

I grew up in a small town. I was only ten years old when my dad gave me the responsibility of feeding the chickens and cleaning up the stable (马厩). He believed it was important for me to have those jobs to learn responsibility. Then, when I was 22, I found a job in Natchbill at a country music club called the Natchbill Palace. I washed dishes and cooked from 4:00 pm to 9:00 pm and then went on stage and sang until 2:00 in the morning. It wasn’t long before I became known as a singing cook. I had been rejected so many times by record companies that it was hard not to be discouraged.
One night, a woman executive (董事) from a company named Warner Brothers Records came to hear me sing. When the show was over, we sat down and talked and after she left, I said to myself it was one more rejection. A few weeks later, my manager received a phone call — Warner Brothers wanted to sign me to a record deal. Soon after, I had my first record in June 1986. It sold over 2 million copies. My best efforts had gone into every job I’ve ever held. It was the sense of responsibility that made me feel like a man.

What should I eat for breakfast? Who should I go out with on weekends? What should I do if I miss the bus to school? What colleges should I apply for? Again and again Chinese kids ask these questions to their teachers and parents. They can’t make their own choices.
Kids in America would be very surprised to hear how much Chinese children depend on adults. When they are ten years old, kids decide what clothes they want to wear and buy. By twelve they know what classes to take for middle school. Thirteen years old is the beginning of being what Americans call a “teenager”. Now the child is up to almost all his / her decisions. Finally at sixteen the kid usually gets a car from his / her parents.
Why should kids be independent? Think about it. After high school most of us will be by ourselves. Will our parents be able to tell us what to eat for breakfast in college? Can our teachers decide what we should do at work?
Making our own choices can be quite hard and scary. But we can start with making small choices, and then slowly make bigger and more important choices.
