For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive （善于接受的） to such messages.
Scientists are using powerful radio telescope to listen to signals from about 1,000 stars, all within 100 light years of earth. In addition, they will scan (扫视) the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy （银河星系）, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent （有智力的） life exists on other planets. Some believe that twenty years of searching without any intelligible （可理解的） messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family in only about five billion years old, our galaxy is about 20 billions years old. In that time, some scientists think it is likely that civilizations are much more advanced than ours. Perhaps these civilizations （文明） send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.According to the passage, how many planets in our galaxy might be inhabitable?

Good nutrition and a balanced diet will help your children grow up healthily. No matter how old your kids are, you can take steps to improve nutrition and to encourage smart eating habits. Here are some suggestions.
Family Meals
Family meals are comforting for both parents and kids. Children like to guess what they are going to have and parents get the chance to introduce new foods to children and to find out which foods they like and which ones they don’t.
Teens may turn up their noses at your plan of a family meal. It is not surprising because they’re trying to establish independence. Yet studies find that teens still want their parents’ advice, so they use the mealtime as a chance to reconnect.
Stocking Up on Healthy Foods
Kids, especially younger ones, will eat mostly what they can get at home. That’s why it’s important to control the supply lines—the foods which you serve for meals and have on hand for snacks. You should have enough fruits, vegetables, lean meat and other good sources of protein, such as eggs and nuts, and healthy snacks, such as yogurt, peanut butter and whole-grain biscuits.
Being a Good Example
The best way for you to encourage healthy eating is to eat well yourself. Kids will follow the lead of the adults they see every day. By eating fruits and vegetables and avoiding fast food and sugary drinks, you’ll be sending the right message.
No Conflicts over Foods
Parents might find themselves shouting at children to get them to have healthy foods in front of them. This in fact can make children dislike what they are asked to eat.
Get Kids Included
Most kids will enjoy making the decision about what to make for dinner. Talk to them about making choices and planning a balanced meal. It can help prepare them to make good decisions on their own about the foods they want to eat.

“Hey, Sheba” she said, “I’ve got no time for you now, but I’ll take you out as soon as I get back from tennis club.” Then she noticed Sheba seemed to be coughing or choking. Obviously, she could hardly breathe. Immediately Joanne realized she would have to take her to the vet (兽医). When she got t
here, the vet was just about to close for the day. Seeing the state of Sheba, Dr. Sterne brought her quickly into his office.
“Listen, doctor, I’m really in a rush to get to a meeting. Can I leave her with you, and go and get changed? I’ll be back in ten minutes to pick her up, and then I’ll take her on to the meeting with me. Is that OK?”

Quality after-school programs are designed to improve academic performance, decrease youth crimes and other high -risk behaviors, and help young people grow into healthy, successful adults.
The effect of quality after-school programs on academic performance is clear. Studies show that students who take part in such programs show better work habits, higher rates of homework completion, improved grades, and higher scores on achievement tests. They also have fewer absences and are less likely to blame. After-school programs also influence high-risk teen behavior. Various studies show decreased rates of crime, drug use, and teen sex among youth who join in well-run after-school programs when compared to similar youth who do not. Finally, after-school programs play an important role in supporting the following fields of development: physical development, mental development and social development. Thus, one can safely say that after-school programming is an effective method to help young people become contributing members of society.
Although there is enough proof from both small and large assessments that after-school programs can make a positive difference, it is important to note that not all programs are equal. First, dosage（时量）matters —young people who attend the most hours over the most years benefit more than members who attend less often or over a shorter period of time. Next, after-school programs make a bigger difference for those students who need help most and have the fewest choices. Finally, program qualities matter. After-school programs work best when they create unique opportunities for youth. They should provide opportunities, skill building meaningful involvement, expression suggestion, service, and work. Staff characteristics make an important difference in the quality of a program. The adults should treat youth as partners, create safe and fair environment, encourage personalized involvement, and actively create learning opportunities. In short, although after-school programs have promising future, how they are designed and run matters.
1. Quality after-school programs can not help the students.
A. have fewer attendances B. improve academic performance
C. have high scores on tests D. decrease high-risk teen behavior
2. According to the passage, a good after-school program is usually determined by .
a. its unique opportunities b. safe and fair environments
c. work staff characteristics d. students’ willingness and family backgrounds
A. a, b, c, d B. a, b, c C. a, c, d D. b, c, d
3. The main intention of the writer is to.
A. present the problems with quality after -school programs
B. warn school leaders of quality after-school programs
C. compare quality after-school programs with bad ones
D. give an introduction of quality after -school programs
4. Which of the following structures suits the passage best?
A. Quality Aims
After-school Effects
Program Analysis Conclusion
B. Quality Aims
After-school Causes Effects Program Analysis Conclusion
C. Quality Aims
After-school Causes Conclusion Program Analysis
D. Quality Aims

In 2001, 11-year-old Kevin Stephan was a bat boy for his younger brother's Little League team in Lancaster, New York. It was an early evening in late July. Kevin was standing on the grass away from the plate, where another youngster was warming up for the next game. Swinging his bat back and forth, giving it all the power an elementary school kid could give. The boy brought the bat back hard and hit Kevin in the chest. His heart stopped.
When Kevin fell to the ground, the mother of one of the players rushed out of the stands to his aid. Penny Brown hadn't planned to be there that day, but at the last minute, her shift(换班)at the hospital had been changed to see her son’s performance. She was given the night off. Penny bent over the senseless boy, his face already starting to turn blue, and giving CPR, breathing into his mouth and giving chest compressions. And he revived in the end.
After his recovery, he became a volunteer junior firefighter, learning some of the emergency first-aid techniques that had saved his life. He studied hard in school and was saving money for college by working as a dishwasher in a local restaurant in his spare time.
Kevin, now 18, was working in the kitchen when he heard people screaming, customers in confusion, employees rushing toward a table. He hurried into the main room and saw a woman there, her face turning blue, her hands at her throat. She was choking.
Quickly Kevin stepped behind her, wrapped his arms around her and clasped his hands. Then, using skills he'd first learned in Scouts. The food that was trapped in the woman's throat was freed. The color began to return to her face.
"The food was stuck. I couldn't breathe," she said. She thought she was dying. "I was very frightened."
