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 have 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．

The passage mainly about

A. a way of preventing building from breaking down

B. a series of earthquakes in Haiti and Chile

C. a way of warning before buildings collapse

D. a newly-discovered structure of a molecule

According to the passage，we can conclude that

A．there are problems to solve before putting the new material to use

B．scientists have found the life circle of buildings from “birth” to “death”

C．bright fight makes the red color visible to human eyes

D．the new material is unlikely to be used in building bridges

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

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 stretched etched

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

Last weekend, my kids along with a few other kids from the neighborhood volunteered to help me wash my car．My 10-year-old daughter came up with the idea of 1 other people’s cars as well．It was pretty   2   outside and I had no plans to   3   being in the bright sun．She   4   wanted to give lemonade（柠檬汽水）to passers-by for free．I had seen little kids 5   and sell fresh lemonade for a small cost but not free．Although I felt   6 , I decided to help her．
7   she asked me, “What if we 8 this a smile car wash?” I couldn’t hold back my tears and   9   her and the other kids to go outside the house and           10  creative ideas．While I kept myself busy in drying the car, the gang walked up to me with a（n） 11   with beautiful images of smiles．They had “Free Car Wash” written on it and the   12   of their exercise was “smile”．It was pretty neat to see a team of kids ranging 5-11 years with the   13    to do something for others．
All that seemed   14   and came right from their heart．Nothing seemed to   15 to them: their playtime, the heat outside—they just wanted to   16 others and do something nice in the community!
I helped them make some fresh lemonade and brought out some additional   17 to help clean cars．Passers-by were   18 and one even shouted back to them saying “God Bless You, my kids…” One of them even tried giving them 5 dollars, which they   19 ．A pretty heartwarming  scene !
I felt blessed by being surrounded by such wonderful and loving   20 ．

The future is time that is to come. The future is not the present or the past. It is later. We have seen many possible futures in science fiction. They range from the world’s polar ice caps melting to nuclear winters. But not all futures are this morbid. We have seen the human race spread all over our universe, humans and aliens living in harmony together all over the universe.
It is very likely that we will make some kind of breakthrough in our ability to travel through space sometime in the next 150 years. This would give us the ability to rule other planets. Ultimately, the earth will die whether it be 1,000 years or 100,000 years. We will be forced to move to another planet then. It’s really just a matter of time. When we do so, what will we discover?
Personally, I think everyone will be speaking the same language in 200 years. A world government definitely seems to be in our future. It is stable and has few wars. Indeed, the only type of wars that can happen is the civil war.
And what if we face aliens? If they are friendly, we would probably benefit a lot from putting our knowledge together. They must have advanced technology to travel for great distances. We could seriously benefit from their technology. But if they aren’t friendly, then we are in trouble. Hope that we have become advanced enough, smart enough, and generally a better race by the time we meet them. But this is all probably being discussed for nothing, because any race out there among the stars is probably as curious as we are about other creatures.
