Read the following article and answer the question. Article: Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc. In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer. Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer. The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity . While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby , men. These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight. Question: 67.

- the effect of exercise on reducing chances of cancer
- how to lose weight effectively

Read the following article and answer the question. Article: One of the most recent social changes taking place in the world is social networking. Social networking has been in existence for at least 150 years, and probably longer than that. In the times before the invention of the computer and the World Wide Web (WWW), social networking was done in person. People who had similar likes and interests would gather together to share experiences, make new friends, and improve their businesses. On the Internet, social networking websites made their first appearances during the late 1990s. The first major social networking website in the United States was MySpace. MySpace allowed its users to exchange messages, share pictures, and make new friends in a way that was never thought of in the past. With MySpace, people who did not go out much could reach out to others from their own homes. In 2004, Facebook was created. It was first a website created for use by Harvard University's students and teachers, but it soon expanded to include just about everyone. It is now larger than some of the largest companies in the world. It is a website that is changing all the time. Facebook has completely changed the way people stay connected with each other and the rest of the world. The way it works is simple. Users can set up a new account easily. All a new user needs is an email address to start. Once a person has created an account and his friend also has his own Facebook page, he can invite his friend by sending a request out to him. Once you get started, making new friends will come easily. Question: What does the passage mainly tell us? Answer:
OPTIONS:
- The way to be a Facebook user.
- The importance of social networking.
- Two important social networking websites.
- The differences between MySpace and Facebook.

Answer: Two important social networking websites.

Read the following article and answer the question. Article: When doctors urge overweight kids to pick up more activities,reading probably isn't what they have in mind. Yet a new study by fatness researchers at Duke University finds that the simple act of reading--depending on the choice of material--can cause weight loss in teenage girls. The study's experimental group included 31 fat girls aged 9 to 13,who took part in the Healthy Lifestyles Program at Duke Children's Hospital. The girls read a novel called Lake Rescue,whose protagonist is an overweight teenager who struggles with low selfesteem,feelings of loneliness and teasing because of her size. A group of 33 girls read a different book called Charlotte in Paris,which did not have an overweight character,and another group of 17 girls read neither book. At the end of the sixmonth experiment,all the girls who read books had lost weight,but the girls who read Lake Rescue lost more. They lowered their body mass index (BMI) by 0.71,compared with 0.33 in the Charlotte group,an average 0.05 increase among the nonreaders. The idea behind the study,says Dr Sarah Armstrong,director of Healthy Lifestyles,was to find a way to encourage the girls without adopting the restrictive and often authoritative voice of so many other nutrition and diet programs. Lake Rescue was the perfect instrument,says Armstrong;it presents a likable character to whom the girls could relate and whom they could learn from. As the book progresses,its protagonist learns to make healthier lifestyle choices and finds an adviser to help keep her on track. Armstrong says," _ learns that she can become healthier,and the 'I can do it' feeling resonates with the teenage girls." Question: According to the passage we can know that _ . Answer:

- overweight girls are living unhappily
- reading is the best way to lose weight
