AIncluding the following food or fruit in your breakfast makes you healthier and full of energy.Grapefruit“Even if you changed nothing else about your diet, eating half a grapefruit before each meal may help you lose up to a pound a week,” says Patricia Bannan, author of Eat Right When the Time Is Right. “Researchers found that when obese people ate half a grapefruit before each meal, they dropped an average of 3.5 pounds over 12 weeks,” she says.Tart CherryTart cherries have been shown to benefit heart health as well as body weight in a study on obese rats. A 12-week study by the University of Michigan found that rats fed tart cherries showed a 9 percent belly fat reduction. Moreover, the researchers noted that the cherry consumption had great ability to alter the expression of fat genes. Enjoy them during breakfast to kick your morning off right.Sweet PotatoSweet potatoes are packed with nutrients and can help you burn fat. They are high in fiber and have a low glycemic index (血糖指数), which means they are absorbed slowly and keep you feeling full longer.

It is very filling, which helps keep appetite and portions under control as the day goes on,” she says.Bell PepperGreen, red or yellow, fresh or frozen, peppers are never a bad companion for your eggs.

Agriculture.D. Technology.BMost people think their time problems are outer, and that they are caused by telephones, meetings, visitors, and delayed information or decisions. Although these problems often have a bad effect on us, as people call or drop in, we usually contribute to them, we fail to have calls screened by a skillful secretary or assistant, or we leave our door open, actually assuring constant interruptions.In almost all cases, it is possible to control. If not controlled, it usually can cause problems, such as, slowness and indecision, lack of self-discipline, the inability to delegate, or the tendency to fight fires, to act without thinking, and to jump from task to task without finishing any of them.Time is constant and it cannot be changed. The clock cannot be slowed down or sped up. Thus we cannot manage time itself. We can only manage our activities with respect to time.The same skills are needed as those used in managing others—the abilities to plan, organize, delegate, direct, and control. Time management is simply self-management. It is impossible to be effective in any position without controlling one’s time effectively.Successful time management does not mean working harder, but working smarter. All kinds of management skills must be used in the home and office to get most value from time. You must think ahead about what to do, making it get maximum results in the shortest possible period.4.

That’s the placeswhere students spend so much of their time. Although hours of studying burn mental energy, both your body and mind need physical exercise to function efficiently.The importance of exercise is nothing new. Thomas Jefferson once wrote that to be successful in academic studies, a person should spend two hours on exercise every day, for health must not be sacrificed (牺牲) for learning.A strong body makes the mind strong.It turns out Jefferson was on to something. A study by researchers at Tufts University found that students who said they exercised at least 3 days a week were more likely to report a better state of physical health and greater happiness than those who didn’t exercise. This and other evidence suggest that the real benefits of exercise may not come right after a workout but from a longer commitment to regular activity.But experts today do not demand 2 hours of daily exercise. The U.S. Department of Health and Human Services recommends that people get at least 60 minutes of physical activity most days of the week.Walking, jogging and swimming are easy ways to increase your heart rate and improve health. Exercise can also help lower blood pressure and reduce stress. For women, exercise that makes the body and bones bear weight—like walking or running—may reduce the risk of osteoporosis (骨质疏松) later in life.You’ll likely discover another benefit of exercise as well: greater self-confidence. This may make it easier for you to participate in class and help you perform well in academic and social situations.7. It can be inferred from the first paragraph that ________.A. a lot of students like to read while eatingB. dining halls can also be used to do exerciseC. study and exercise burn the same amount of energyD. many students don’t pay enough attention to exercise8.
