1 . One day, you open the fridge and find some moldy (发霉的) food. But before you can throw it away, your mother stops you. She wants to cut off the moldy part and eat the rest. Is it safe to do this?
Mold (霉菌) can grow on almost all kinds of food. Mold is usually green, white, black or grey. Mold makes food soft and changes its color. Moldy food tastes quite bad and it’s not safe to eat. If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains water inside. And the water inside allows mold to easily grow below its surface. Bacteria (细菌) can also grow along with it.
But it’s easy to clean mold from hard food. The mold can’t grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold to clean it. It’s OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, throw it away.
Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, penicillium (青霉菌) can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat and they’re quite delicious as well.
So, if the food is not the special cheese, stop your mother from eating it!

It used to be that people would drink coffee or tea in the morning to pick them up and get them going for the day. Then cola drinks hit the market. With lots of caffeine and sugar, these drinks soon became the pick-me-up of choice for many adults and teenagers. Now drink companies are putting out so-called “energy drinks.” These drinks have the specific aim of giving tired customers more energy.
One example of a popular energy drink is Red Bull. The company that puts out this drink has reported that Red Bull is not a thirst quencher (解渴饮料). Instead, the drink is meant to revitalize (使恢复生机) a tired customer’s body and mind. In order to do this, the makers of Red Bull, and other energy drinks, typically add vitamins and certain chemicals to their drinks. The added chemicals are like chemicals that the body naturally produces for energy. The vitamins, chemicals, caffeine, and sugar found in these drinks all seem to give a person energy.
Health experts are not so sure, though. For one thing, there is not enough evidence (证据) to show that all of the vitamins added to energy drinks actually raise a person’s energy level. Another problem is that there are so many things in the drinks. Nobody knows for sure how all of the ingredients in energy drinks work together.
Dr. Brent Bauer cautions (告诫) people about believing all the claims (申明) energy drinks make. He says, “It may be true if you put these twelve things together, you will get a good result.” However Dr. Bauer adds the mix of ingredients could also have a negative impact (负面影响) on the body “We just don’t know at this point,” he says.
1. Which of the following can be found in most energy drinks?①Caffeine ②Sugar ③Vitamins ④Thirst Chemicals
| A．①②③ | B．①②④ | C．①③④ | D．②③④ |
| A．The age of the customers. | B．The number of ingredients. |
| C．Natural chemicals in a person’s body. | D．The company that makes the drinks. |
| A．Drinks for teenage athletes. | B．Vitamins and chemicals in the body. |
| C．Countries where Red Bull is popular | D．Habits of healthy and unhealthy adults. |
| A．Red Bull is a good energy drink. | B．Caffeine is bad for people to drink. |
| C．Energy drinks may or may not work. | D．Teenagers should not drink energy drinks. |
6 . Here is some advice from three doctors. If you’re in one of it, you can choose it.
Drinking hot water without anything in it is very useful, if you have a fever or have a cold. Water can make something dirty out of your body. It can also lower (降低) your blood pressure (血压). Don’t drink too much water at once, because it’s bad for your stomach. It shows you drink enough when you feel full. Mr. King |
When you cough, you can’t eat or drink something sweet like sweet milk, cakes and sugar. You should eat something light such as vegetables and fruit, and drink hot water. Don’t eat peppers. You can’t drink or eat something cold, either. They’ll make you cough worse. Drinking some hot pear water is a good way to keep you off cough. Mr. Green |
If you have a stomachache, you can’t drink wine (酒) or eat peppers. You can’t drink thick (浓的) tea, coffee and something too cold or hot. You can eat porridge or noodles and drink soup. Staying up late at night and keeping too worried may be bad for your stomach. You need to drink more water, take some medicine and take exercise to keep your stomach healthy. Mrs. Smith |

I like eating fruit, but I don’t like eating meat. I sleep for eight hours a day. I want to be tall. I am taking medicine. I think that medicine can make me grow tall. My head teacher tells me that you are a great Chinese doctor. Can I grow tall? Do I need to take the medicine? Yours, Tom |
| Dear Tom, I think that you can grow tall, because your father and brother are both very tall. You are still growing. As for the medicine, you should stop taking it. It is not good for your health.

| A. Exercise, or even just spend an hour jogging. You need to move. Even a walk is quite healthy if you can keep it for 30 minutes a day. Walking to the subway and taking it instead of driving a car is a good way to help you exercise more and lose more weight. B. Sleep earlier. Your body has a better rest when you go to bed earlier. Enough sleep helps you to work more effectively. A good sleeping habit will be good for your health. Try to contact your doctor if you can’t fall asleep or often wake up during the midnight. C. Eat more vegetables and cut down junk food. Junk food is bad for your health. It’s hard to change your eating habit in a short time. But don’t forget the fact that health is more important. D. Always have breakfast. A good life starts with a good breakfast, which keeps you in a good mood and full of energy the whole day. Try to develop a good living habit by eating less in the evening. You are sure to feel hungry in the morning. E. Don’t let yourself be very hungry. If you eat something before you are very hungry, you’ll eat less. If you eat right after you find yourself hungry, you’ll eat more than you really need. F. Think twice about joining weight loss programs. Some of such programs couldn’t work for some people. You may get hurt if you don’t follow the correct instruction. To lose weight healthily, you can visit websites such as eDiets. G. Visit your doctor twice a year. Go to a doctor for some tests even if you are well. If you have tests twice a year, you can get to know the problems inside your body as soon as possible. |
Sometimes it may seem difficult to improve our health.
Eat breakfast every morning.
Research shows that if you eat a meal in the morning, you may not become too fat or eat too much during lunch. Eating breakfast can help people feel better through the day.
Poor sleep can influence our memory and learning. It can also cause traffic accidents! Studies show that people who don’t get enough sleep seem to get into more accidents. So get enough sleep and stay safe!
Take a walk every day.
Walking is an easy way to exercise. You’d better meet friends for a walk, not for a meal.
Join social groups.
Social groups can provide support. They might include sports teams, art or music groups. The people in the group can offer advice and help each other in difficult times.
