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.

    Liu Tuchi, an 87­year­old man, has given away thousands of books to kids in five villages in Southwest China and built some reading rooms in the past 13 years by collecting and selling rubbish.

    "After selling the rubbish, I go to bookstores to search for good books," Liu said. When he has enough books, he sends them to the kids in the villages.

    Liu was an officer in Sichuan Province before retiring (退休) in 1993. "I passed by a primary school in Qilong Village in 2005 and was shocked by the poor conditions," he said. With old classrooms and broken desks, the students hardly had any books. So Liu took out more than 5, 000 yuan and raised more than 8, 000 yuan from his family and friends to give away books to the school. Since then, he has kept on giving away books to rural (农村的) kids.

    Liu's work has opened his new lifestyle (生活方式). He collects and sells waste, such as bottles and old newspapers. In 2008, Liu started building reading rooms. So far he has built more than 15 reading rooms. Liu always says, "Children in rural areas should not be left behind, especially in education."

    How do you get to school? Do you walk or ride a bike? Do you go by bus or by train? For many students, it is easy to get to school. But for the students in one small village in China, it is difficult. There is a very big river between their school and the village. There is no bridge and the river runs too quickly for boats. So these students go on a ropeway to cross the river to school.

    One 11-year-old boy, Liangliang, crosses the river every school day. But he is not afraid. "I love to play with my classmates. And I love my teacher. He is like a father to me."

    Many of the students and villagers never leave the village. It is their dream to have a bridge. Can their dream come true?

    Confidence(自信) is very important in daily life. It can help you to develop a healthy attitude (态度). A study shows that the people who are more confident are much happier. They can have more chances to make themselves successful. But how to be more confident? Here are some suggestions:

    Speak loudly When you are not confident，you can't do well what you want to do. You speak in a voice so low that other people can hardly hear you. Try to speak loud enough so that people can understand you clearly. The high voice can help you become more confident.

    Play sports Playing sports makes you tired but completely relaxed. When you do sports，you will be full of confidence.

Encourage yourself Write down a list of things you did during the day and see how many things you have done well. Did you finish your homework? Did you tell a joke that made everyone laugh? Give yourself praise for the good things you've done.

    Get rid of(消除) fear Fear comes along with failure(失败).But it's easy to get over(克服) if you know that failure is part of your life. Don't hide your head just because you said something stupid last time. Try to start again and believe you can do better.

    Pick up what you like to do If you like singing, sing as much as you can. In some ways, a hobby can make you excellent. And it will make you happy and confident.
