【推荐1】Many people want to know how to help kids be fitter. There are some steps only parents can take, but kids can take charge, too.     1    

1. Eat a variety of foods, especially fruits and vegetables.     2     In that case, you’re more likely to get the nutrients your body needs. Shoot for at least five servings of fruits and vegetables a day—two fruits and three vegetables.

2.     3     When you’re really thirsty, cold water is the No. 1 thirst-quencher (饮料). And there’s a reason your school cafeteria offers cartons of milk. Kids need calcium to grow strong bones, and milk is a great source of this mineral. Aim for 3 cups of milk per day, or its equivalent.

3. Listen to your body. What does it feel like to be full? When eating, notice how your body feels and when your stomach feels comfortably full.     4    

4. Limit screen time. Screen time is the amount of time you spend watching TV or DVDs, playing video games, and using the computer.     5     Try to spend no more than 2 hours a day on screen time.

5. Be active. One job is to figure out which activities you like best. Not everyone loves baseball or soccer. Maybe your passion is kickball, or dancing. Ask your parents to help you do your favorite activities regularly. Find ways to be active every day.

A．The following healthy foods can be of great help to your body.

B．Eating too much can make you feel uncomfortable and, over a period of time, can lead to unhealthy weight gain.

C．You may have a favorite food, but the best choice is to eat a variety.

D．If you, a kid, want to be fit, the following may be useful.

E．Go to bed early and get up early.

F．Drink water and milk most often.

G．The longer you spend on these sitting-down activities, the less time available for active stuff, like basketball, and swimming.

【推荐2】Scientists have long known that humans are built for endurance. Now, a new study shows people's hearts are also bettered for endurance — though how much depends on whether we run, farm, or stay put on the sofa.

To get to the heart of the matter, researchers examined the hearts of more than 160 adult men from four groups: long-distance runners, sedentary adults, highly trained football player, and the Tarahumara, native American farmers famous for their running ability.

When researchers compared the thickest of the heart's ventricles, they found there were clear differences. Endurance runners and farmers had larger, longer ventricles with thin walls, which could help pump more blood for a long time, the researchers report today in the Proceedings of the National Academy of Sciences. The football player, whose training was short, high-intensity exercise, had shorter, wider ventricles with thicker walls. So did the sedentary humans.

Because high-intensity activity causes blood pressure to increase for a short amount of time, such shorter ventricle, thick walls, and rounder shapes are good for the football players, researchers say, by making sure enough blood is pumped to the brain. But even without those pressures, a couch potato lifestyle seems to result in the same kind of thickening.

But sedentary readers shouldn't feel heartbroken — the researchers said that changes in heart shape are likely reversible, with more endurance activities.

1. What was the aim of the research into hearts?

A．To work out why humans are built for endurance.

B．To make out what kind of ventricle is the healthiest.

C．To figure out whether hearts are bettered for sedentary adults.

D．To find out how endurance activities can make our hearts better.

2. Jimmy is a computer engineer who has to work for long hours on computer. Which of the following ventricle and walls may suit him according to the passage?

A．	B．
C．	D．

3. What will the passage talk about following the last paragraph?

A．Introduction to endurance activities.	B．Benefits of heart shape.

According to a study following about 3,600 American adults, almost one-third of them watched TV for more than four hours a day. More than one-third of them spent between two and four, hours on TV a day. The rest watched TV for less than two hours a day. Compared to people who watched less than two hours of television daily, those who spent more than four hours on TV were 49 percent more likely to die or have a heart attack. But the bad health effects of TV appeared to be limited to adults who failed to get there commended amount of weekly exercise. That is around 150 minutes of moderate(适度的) physical activity or 75 minutes of strong exercise every week.

Annie Brown, a researcher at the University of Calgary, says it is possible that sitting in front of TV might be worse than sitting at a desk because people snack while watching TV. Some people stay up too late and do not get enough sleep. “Eating treats or lack of sleep could both cause weight gain and increase risk factors for heart disease. These factors could make people more likely to die early”, she added. Annie explained that “the evidence on TV viewing and health risks is strong.”

Arch Mainous is a researcher at the University of Florida. He said that it would be a mistake for people with desk jobs to think there is no need .to get moving during the workday. “Take the stairs rather than the elevator, or take a walk at lunch”, Mainous advised. “Leisure time physical activity is definitely beneficial, but walking more steps in the workday should also be encouraged.”

D．Harmful.

3. What may Arch Mainous advise us to do?

A．Have-lunch out of the office.

B．Try to get enough sleep.

A．Overeating, overweight

B．Sit before TV long, die young

【推荐2】Photography was once an expensive, laborious experience reserved for life's greatest milestones（里程碑）. Now, the only apparent cost to taking infinite photos of something as common as a meal is the space on your hard drive and your dining companion's patience.

But is there another cost, a deeper cost, a deeper cost, to documenting（记录）a life experience instead of simply enjoying it? "You hear that you shouldn't take all these photos and interrupt the experience, and it's bad for you, and we're not living in the present moment," says Kristin Diehl, associate professor of marketing at the University of Southern California Marshall School of Business.

Diehl and her fellow researchers wanted to find out if that was true, so they embarked on a series of nine experiments in the lab and in the field testing people's enjoyment in the presence or absence of a camera. The results, published in the Journal of Personality and Social Psychology, surprised them. Taking photos actually makes people enjoy what they're doing more, not less.

"What we find is you actually look at the world slightly differently, because you're looking for things you want to capture, that you may want to hang onto," Diehl explains. "That gets people more engaged（参与）in the experience, and they tend to enjoy it more." Take sightseeing. In one experiment, nearly 200 participants boarded a double-decker bus for a tour of Philadelphia. Both bus tours forbade the use of cell phones but one tour provided digital cameras and encouraged people to take photos. The people who took photos enjoyed the experience significantly more, and said they were more engaged, than those who didn't.

Snapping a photo directs attention, which heightens the pleasure you get from whatever you're looking at, Diehl says. It works for things as boring as archaeological museums, where people were given eye-tracking glasses and instructed either to take photos or not.

"People look longer at things they want to photograph," Diehl says. They report liking the exhibits more, too. To the relief of Instagrammers everywhere, it can even make meals more enjoyable. When people were encouraged to take at least three photos while they ate lunch, they were more immersed in their meals than those who weren't told to take photos.

Was it the satisfying click of the camera? The physical act of the snap? No, they found; just the act of planning to take a photo—and not actually taking it—had the same joy-boosting effect. "If you want to take mental photos, that works the same way," Diehl says. "Thinking about what you would want to photograph also gets you more engaged."
