It's getting hotter and hotter outside. Summer is already here! Summer means high temperature, more outdoor activities and all kinds of fruit and vegetables. How can we stay fit in this exciting season? Here are some good ideas:

 Eat and drink properly

 What is healthy to eat in summer? Fresh and light food. Fish can be a good choice. It can keep your body energetic and help fight against the burning sun. Colorful fruit and vegetables is another good choice. They not only please your eyes, but are full of healthy chemicals(化学物质). Tomatoes can help protect your skin against sunburn. Blueberries are good for your brain and eyes. The more color, the better!

With all those summertime activities you will be thirsty. What to drink? Water. Water has zero calories（卡路里）and is the perfect drink to stop you thirst. Try not to drink too many energy drinks, sports drinks and soda drinks which have lots of sugar and caffeine（咖啡因）in them.

 Stay active and cool

Summer is a great season to enjoy outdoor activities and play. It's also a good time to lose weight. If you are lucky enough to be near a body of water, try water sports like swimming, surfing, water skiing and so on. These sports keep you cool and active at the same time. You'll have no problem beating the heat and keeping fit as well.

 Be careful of the          

Summer allows us more chances to get outside, but it also means more possibilities to get burnt by the sunshine. If you are going outside, keep away from the sun when it's the strongest – usually between 11a.m. and 3p.m.. If you have to stay in the sun for a long time, sunscreen（防晒霜），a big hat and a long-sleeve jacket will be necessary.

    What are most 14-year-old boys doing? Going to school, playing sports with friends and doing their homework. But life is much more colorful for the TFBOYS members.

    TFBOYS is a singers' group started in 2013. Its full name is The Fighting Boys. It has three members, Wang Junkai, Wang Yuan and Yi Yangqianxi. Wang Junkai, the group leader, is 15 years old. The other two boys are both 14 years old. When most boys at their age are spending their whole day in the classroom, the three young singers present（展示）themselves to thousands of people. They had made three albums（唱片）and won two singing awards（奖）. Now the three boys are among the most popular singers in our country.

    Many students are interested in TFBOYS, because they are friendly and good at singing. They are still junior high school students. During the week they study at school with their classmates. On the weekends and holidays they have singing class, dancing class and other training. Most of their fans are teenagers. “We are of similar age,” some fans said, “TFBOYS feel like friends to us and we love their songs.”

    Jason Queally is one of the fastest men in the world on a bicycle.

Every year, an important human-powered bicycle race is held in Nevada, the USA. The speed of the bike is measured for only 200 meters, but players take more than a kilometer to get their bikes going fast. Jason Queally's fastest speed for the 200-meterrase was 103.5 kilometers an hour.

    At this year's race, Jason failed to reach the finishing line. He was speeding along about seventy kilometers an hour when he began to lose control of his bike. When he tried to slow down, it began to smoke. Soon the inside of his bike was filled with smoke. He couldn't see, and he couldn't breathe. At seventy kilometers an hour, a crash could be very serious. Jason was frightened, but he managed to stop the bike safely. He would repair his bicycle and try again another time to be the world's fastest man on a bike. Better luck next time, Jason.

The most amazing one was when they had to exchange things worth a thousand yuan with only a piece of paper in half an hour.
