2 . ①Nowadays, people always make up their mind to give up sugar, but they always end up with failure. Why is sugar so powerful, and how can you beat it?
②Many sugar cravings (渴求) come from a blood sugar imbalance (不平衡). When your body takes in sugar, your blood sugar quickly goes up and your body lets insulin (胰岛素) out to lower it to a safer level. But if your blood sugar level is too low, your body will want more food to raise it.
③Some sugar cravings are from your brain as a result of lifestyle. For example, if you are too stressed, you will be thirsty for sugar to cheer yourself up. Besides, poor sleep can also lead to overeating sugar, because you need energy to free yourself from tiredness.
④ Sometimes the cravings come from a habit. Perhaps you watched your parents overeat sugar throughout your childhood. Now you do the same, eating pie, for example, even though you are not hungry at all. Or you may eat sweet food like chocolate or ice-cream to reduce (减少) sadness.
⑤ The key to dealing with sugar cravings is to eat foods that stop too much insulin from being released. Healthy fats and protein (蛋白质) are good choices. Protein helps you feel satisfied, which can cut down hunger.
⑥You may find it is hard to give up sugar totally. But once you start to deal with it, you can beat sugar and have a healthy life.

3 . Today, more and more people care about their health. But how can we stay healthy?
First of all, it helps to do some exercise every day. Doing exercise helps your lungs (肺部) work harder and your heart beat faster. This makes your heart stronger and cuts down on your risk of heart disease. You can start with some daily exercises, such as walking, running and dancing to music. You can also play ball games, including basketball, volleyball, ping pong and more.
Second, what you eat is also important. According to doctors, you’d better eat more fruits and vegetables and less meat. This is because meat has more fat in it. When too much fat builds up in your body, it can block your blood flow (阻塞血液流动). This can lead to a heart attack (心脏病发作).
Finally, ________, such as going to bed too late. You may clearly know the dangers of such habits. What you need to do is make up your mind to change yourself. If you follow these tips, you are sure to become a healthier, stronger person!

“Early to bed and early to rise, makes a person healthy, wealthy and wise.” These words of Benjamin Franklin have been backed by science. It has been proved that morning people are persistent and active. It leads to better performance, greater success, and higher standards of living. Rising up early also reduces stress because it gives you the time to squeeze in a workout before you get distracted(心烦意乱的).
Recent research has found that late sleepers generally need about 248 more calories than those who rise early. They prefer to only eat half as much fruit and vegetables and twice as much fast food as those early risers.
If you get into the habit of rising early and going to bed early you are more likely to have a better sleeping pattern.

6 . Most people know how to keep their body healthy, but not many people think about how to keep their brain (大脑) healthy. Brain health is very important. It can help to make your brain work better and to stay away from some brain problems, such as strokes (中风).
Our reporter Judy is speaking to Dr. Fida Cortez, professor of psychiatry about brain health.
Dr. Cortez: We must eat healthily. One of the best ways for the brain to get energy is from whole grain foods, like bread and rice. They can keep the brain working hard for longer.
Judy: Is fat important? What kind of fat should we eat?
Dr. Cortez: The brain needs fat to work well. Fatty acids (酸) are healthy fats found in fish and nuts. Fat from fast food like hamburgers is not good for the brain; it stops the brain using the fatty acids well.
Judy: People talk about berries a lot. Are they a “super food”?
Dr. Cortez: Yes, berries are very good for the brain. Blueberries, strawberries and blackberries are full of something called antioxidants. They help the brain to stay healthy.
Judy: What about sleep?
Dr. Cortez: Sleep is important. It is difficult for your brain to work well if you haven’t had enough sleep; too much sleep is also bad. It can make you feel tired.
Judy: We know exercise is good for our bodies. Is it good for our brain?
Dr. Cortez: Yes, exercise is another good way to take care of the brain. It makes the blood move to the brain more easily and quickly.

8 . As people all over the world struggled with higher levels of stress, depression and anxiety this past year, many turned to their favorite comfort foods: ice cream, pizza, hamburgers. But studies in recent years suggest that the high-sugar and high-fat foods when we are stressed or depressed, as comforting as they may seem, are the least likely to be good for our mental (精神上的) health. Instead, whole foods such as vegetables, fruit, fish, eggs, nuts may be a better bet.
Historically, nutrition research has paid much attention to how the foods we eat influence our physical (身体上的) health, rather than our mental health, though. Over the years, large population studies have found that people who are asked to follow a Mediterranean diet for three months had greater reductions in symptoms of depression after three months compared to a control group. Public health professors around the world have started encouraging people to take and use lifestyle behaviors like exercise, sound sleep, a heart-healthy diet and avoiding smoking that may reduce inflammation (发炎) and have advantages for the brain. Individual clinicians (临床医师) are already including nutrition into their work with patients. Dr. Drew Ramsey, a clinical professor at the Columbia University, begins his meetings with new patients by exploring their diet. He asks what they eat, learns their favorite foods, and finds out if foods that he considers important for the connection are missing from their diets, such as plants, seafood.
Dr. Ramsey said he didn’t want people to think that the only factor involved in brain health is food. “Lots of people get their food exactly right, live very active lives, and still have many troubles with their mental health,” he said. But he also teaches people that food can be empowering. “We can’t control our genes,” he said. “But we can control how we eat, and that gives people actionable things that they can do to take care of their brain health on a daily basis.”

| A．Some connection lives between our diets and mental health. |
| B．People can control their genes as well as how they eat. |
| C．People living active lives will not have mental problems. |
| D．Eating a healthy diet is going to cure depression. |

10 . Boys and girls, how is your body? Now let’s imagine that your body is like a big factory. It takes in “materials” and puts out “goods”. If you start with poor materials, it’s likely that your goods won’t be high-quality. But if you use better materials, your goods will come out much better.
What does this mean in real life? It means getting the right amount of sleep, eating food that is good for you, and exercising more often. You might not think about this much as a young student, but please believe in me that it becomes much more important as you get older.
It is very good to start building a better “factory” at a young age. Getting into the habit of living healthily can help you a lot in many ways. If you get enough sleep—not too little or not too much, you will be able to focus better on your studies. Eating healthy food helps your body grow strong and fight off sickness. And exercise can help you stay fit both physically and mentally.
This sounds like a lot to do. So start small—try to go to bed at the same time each night and wake up at the same time as well. Find time to eat a single apple each day—people often say “an apple a day keeps the doctor away”. Try to exercise each day, even if it’s only for 10 minutes. Doing these little things will help you build a great “factory”.
