Some years ago, Danny gave up his job as a doctor to become a freelance(特约的) model maker, but now he has money trouble. He says that he wishes he'd never 1 to set up his own business.

    "I am now in such a bad situation," says Danny. "I hope I'm 2 working as a doctor. You see, I was 3 with my job, and I didn't have any fun. I said to a few friends that I wanted to go into 4 and they said that they could give me work, so I left the hospital.

    At first, everything was 5: I had too much work to do. I got too many orders every day. And soon I 6a large number of money. I had a really great lifestyle, and when the work was finished, I used to take good 7 in places like the beautiful blue Aegean Sea, Maldives, Hawaii and so on, just to get relaxed.

    Like this, I was busy having fun all around the world, and charged (支付) everything to my credit (信用) cards, but then I began to 8 how much in debt (负债) I was. At last, I had to sell all my office equipment (设备). Now I could do almost 9 even if people asked me. I've had to 10 my business now and I don't know what I'm going to do for money. It just goes to show if you set up your own business, you shouldn't spend money you don't have."

    Don't throw away your old phones. You are actually throwing away real gold! Smartphones have many kinds of useful metals. People can recycle them to make new electronics.

    But many people may not know this. In Australia alone there are more than 25 million unused mobile phones lying around, The Sydney Morning Herald reported. The gold in these phones can add up to a value of more than $80 million. There are about 2 billion smartphone users around the world, who change their phone once every 11 months on average. So in China, eighty million old phones come along every year.

    However, it's not easy to get the useful things out of the phones. Smartphones have not only useful things but also harmful materials. Guiyu, a small town in Shantou, Guangdong, is one of the world's biggest dumping grounds for electronic waste, Reuters reported. Many recycling centers in Guiyu simply break the old electronics by hand and don't think about the pollution it causes. It's reported that 81 percent of children in Guiyu are harmed by lead poisoning(铅中毒).

    Veena Sahajwalla, a professor at Australia's University of New South Wales, has made a mini factory. It makes smartphone recycling cleaner and easier. The mini factory is very small and easy to move around. It breaks the phones and automatically(自动地)removes the phone's useful things. That way, humans do not get poisoned.

    Well, have you ever wondered what happens to the old phone after it's no longer yours? A part of your old smartphone could soon be proudly worn around the neck of one of the world's top athletes. Organizers of the 2020 Tokyo Olympics say that medals for the event will be made from recycled phones. They will also be made out of people's thoughts for avoiding waste. They think there is an important message in this for the future.

    Obesity (肥胖症) is becoming a problem in our busy society, almost one in three American adults is now considered to be obese. Children obesity is also at an all-time high.

    Obesity means being very overweight. If you are obese, you have too much body-fat. If you eat more food than your body can use, this will make you put on weight. Food that your body does not need will be stored (储存) as fat by your body.

    The following are the major factors (因素) that increase the risk of obesity.

    What you eat plays a major role in weight gain. Eating a lot of fattening food such as hamburgers, sweet drinks, ice creams and other sweet food can increase the risk of becoming obese.

    If you do not do enough exercise, you will put on weight as the food you eat is not being used to make energy for physical activities.

    The chances of your being obese are greater if your parents are obese.

    There are many psychological (心理的) factors that cause people to eat too much. People who are worried, unhappy or bored will often eat to make themselves feel better. This is known as comfort eating.

    Age is another factor, as you tend (趋于) to be less active when you get older. When you get older, you need to eat less, and if you do not eat less, you will put on weight.

    Obesity can cause many health problems such as heart problems, high blood pressure and many other serious medical conditions.

Do you like taking a trip? Now many students like riding bikes to take a trip. But it may be dangerous. For your own safety (安全), do the following things.

Follow the rules on the road. Always ride on the right side of the road. Please first look behind you before you turn left or turn right. And don't ride too closely (接近) to the cars--the cars may stop and the door may open suddenly! Also, don't just listen to music when you are riding a bike. If you listen to music, you may not know there is a car behind you. 

If you follow these tips, you'll be safe riding on the road. 

Many people catch a cold in the springtime or fall. Although scientists can send a man to the moon, why can't they find a way to stop the common cold? The 1 is easy. There are actually hundreds of kinds of cold viruses（病毒）out there. You never know which one you will 2 , so there isn't a cure（治疗）for each one. 

When a virus gets into your body, your body works hard to fight against it. When you have a cold, blood（血液）rushes to your nose and makes it stuffy（堵塞的）. You feel 3 because you can't breathe well, but your body is actually "eating" the virus. Your temperature rises and you get a fever, but the heat of your body is 4 the virus. You may feel uncomfortable, but actually your wonderful body is doing everything it can to kill the cold. 

Different people do different things to deal with colds. In the United States and some other countries, for example, people might eat chicken soup to feel 5 . Some people take hot baths and drink warm drinks. Other people 6 medicine to stop the uncomfortable feelings of colds. 

There is one interesting thing to note—some scientists say taking medicine when you have a cold is actually 7 for you. The virus stays in you longer because your body doesn't have a way to 8 it and kill it. Bodies can do an amazing job on their own.
