While scientists are worried that humans are causing higher temperatures on the Earth, a Maryland man, Ace, thinks we can save the world by spraying(喷射)huge amounts of water into the air.
Ace told the McClatchy News Service that at least 1,000 places should be chosen to spray water. The water would be sprayed between 20 and 200 feet into the air. Thousands of tons of seawater would be sprayed for years at a time.
The 1,000 sites would be picked after more studies. They would be mostly in the Northern Hemisphere(北半球). Ace says he would avoid tropical(热带的)areas of the globe. He says water turns to rain too quickly in these areas for his plan to work.
The water would be changed into vapor. That process requires heat. The water vapor would rise above the Earth. The water vapor would form clouds. The clouds would help in several ways. They would cool the Earth by reflecting sunlight. They would later turn into rains. The rains would provide another way of cooling the Earth.
Ace’s plan has gotten some support from a limited scientific study. Kenneth Caldeira is a climate scientist. He works at the Carnegie Institution’s Department of Global Ecology at Stanford University in California. Caldeira tested some of the Ace’s figures on a computer program. The computer model is used by top scientists to study global climate change. The model showed that the plan might work.
“More tests are planned in 2009. Ideas like Ace’s should be considered carefully and with an open mind,” Calderira said. “Every brilliant(卓越的)invention in the history of technology looked a little bit mad when first put forward.”
65.What’s the purpose of Ace’s plan?
A. To reduce air pollution.                  
B. To make summer cooler.
C. To offer dry areas more rain.                  
D. To solve the problem of global warming. 
66.According to Ace’s plan,___________.
A. planes would be used to spray water.       
B. it would be best to spray water on rainy days.
C. seawater would be sprayed high into the sky
D.1,000 sites in the Southern Hemisphere would be chosen.
67.Why wouldn’t Ace spray water in tropical areas?
A. Water is changed into vapor too quickly.      
B. Water turns to rain too quickly.
C. It is hard for vapor to form clouds.           
D. It is bad for local plants to have too much rain.
68. It seems that Caldeira ____________.

In a book called Magnificent Obsession, by Lloyd C. Douglas, a description is given of people helping others but doing it secretly. When difficult problems worried an individual, friends nearby would meet to discuss possible solutions without the individual knowing their actions. When a solution was agreed upon, one or two of the friends would carry out the plan and solve the problem secretly, to the great delight of the worried individual. The helpers would stand by privately, content with their success. No reward was given to the problem solvers, not even a sincere “thank you”, because they were never known.
This concept is popular today but in a different way. The phrase “pay it forward” is now used when one person helps another. However, the person helped may not be able to repay the person or group that helped them. So rather than return the favor to their helpers, they are supposed to help someone else in the future, which means they pay it forward. It is a sense of responsibility which makes us want to give back in equal measure to the one who has helped us. But, in this case, the responsibility turns to helping someone in the future.
Suppose your elderly grandmother pays part of your schooling. She may tell you there is no need to repay her because it is a gift from someone who loves you very much. Nothing would please her more than to have you use her money to get a good education.
You may never be able to repay her for such a gift. However, she not only gave you some money, but she provided you with an example that you should also help other people who need it.
People with serious needs are everywhere. Many are children who need better clothes, more books and even better schools. Some are elderly people who can’t afford their medicine or a doctor’s care. Consider how you can “pay it forward” rather than pay money back to your grandmother.
【小题1】The helpers in the book “Magnificent Obsession” were not rewarded because ________.

A.they hadn’t solved the problems thoroughly
B.they expected to be paid back in the future.
C.they were friends of the worried individual
D.they had solved the problems secretly
【小题2】 The underlined word “pay it forward” means ________.                    
A.to repay someone who has helped you
B.to help someone else who needs help
C.to help someone who has helped you
D.to pay someone else who needs help
【小题3】What does the writer suggest with the example of “your elderly grandmother”?
A.We should also lend a hand to other people in need of help.
B.We should work hard to get a good education.
C.We should learn to respect our grandparents.
D.We should never forget to repay people for their help.
【小题4】By writing the passage, the author wishes people in the world to be ________.

A school in Nanjing plans to order Korean-style school uniforms (校服) for students, but parents were against the move, believing that the new uniforms looked too good and would encourage early romances among the students.
Parents: “My daughter was so excited about the Korean-style uniform, saying it’s her dream to wear a miniskirt to school every day,” a mom said. “My daughter also called her classmates to talk about how handsome the boys looked in the uniforms! If the students wear such beautiful uniforms, how can they concentrate on their studies?”
School: We had to stop the plan because many parents were strongly against it. Some parents thought it was just a way for the school to make money, and others thought the new uniforms would take students’ attention away from their studies.
Students: The students were very disappointed about the school’s final decision. They thought the sportswear uniforms made them look dull. They said the Korean uniforms had many advantages such as raising interest in class and lifting confidence.
As for concerns about romance, the students believe that love is love and has no relationship to the uniforms.
The Department of Education: The schools can choose their own styles. Either sportswear or other uniforms are OK. Currently, most middle and elementary schools in Nanjing have sportswear uniforms.
Expert: Fashionable school uniforms can increase students’ interest in learning.
Parents don’t need to worry too much about early romances. Today’s primary and middle school students have strong personalities and their appreciation of beauty is rapidly forming. A fashionable uniform can develop their sense of belonging to the school and reduce their resistance(反抗) to the school’s management.
But we don’t have to follow Korean or Japanese styles. We should design our own Chinese style uniforms.
1.Students think the new uniforms will________.
    A. make them have good taste in fashion        B. make them feel confident
    C. make them feel proud of their school        D. reduce their fear of teachers
3.The opinion of the expert is to________.
   A. forbid the students to wear fashionable uniforms
B. encourage the students to wear sportswear uniforms
C. design uniforms in a Chinese style
D. wear new uniforms in a foreign style
3.We can infer from the passage that_________.
A. school uniforms are mostly blue or black
B. few students are willing to wear school uniforms
    C. school uniforms are a waste of money
D. schools are encouraged to choose their own uniforms

I woke up late and had breakfast in a hurry. I had never been late and didn’t want my boss to be unsatisfied.
However, it seemed that day wasn’t a lucky one for me from the very second I left my flat. The moment I wanted to rush downstairs one of my stiletto heels (细高跟) broke. I had to return to change my red shoes. I also had to change my purse and other little things that I had tried to match with the shoes. I was sure I would be late for work.

Diana Jacobs thought her family had a workable plan to pay for college for her 21-year-old twin sons: a combination of savings, income, scholarships, and a modest amount of borrowing. Then her husband lost his job, and the plan fell apart.
"I have two kids in college, and I want to say come home. ' but at the same time I want to provide them with a good education," says Jacobs.
The Jacobs family, did work out a solution: They asked and received more aid from the schools, and each son increased his' borrowing to the maximum amount through the federal loan (贷款) program. They will each graduate with $ 20,000 of debt, but at least they will be able to finish school.
With unemployment rising, financial aid administrators expect to hear from more families like the Jacobses. More students are applying for aid, and more families expect to need student loans. College administrators are concerned that they will not have enough aid money to go around.
At the same time, tuition (学费) continues to rise. A report from the National Center for Public Policy and Higher Education found that college tuition and fees increased 439% from 1982 to 2007, while average family income rose just 147% . Student borrowing has more than doubled in the last decade.
"If we go on this way for another 25 years, we won't have an affordable system of higher education," says Patrick M. Calan, president of the center. "The middle class families have been financing it through debt. They will send kids to college whatever it takes, even if that means a huge amount of debt."
Financial aid administrators have been having a hard time as many companies decide that student loans are not profitable enough and have stopped making them. The good news, however, is that federal loans account for about three quarters of student borrowing, and the government says that money will flow uninterrupted.
