When we think summer, most of us think of fun in the outdoors. So it seems easy to lose weight over the summer. In fact, though, it's quite possible for us to put on weight. The good news is that we can avoid these problems if we know what to pay attention to.

    Here are some ways to keep summer weight away.

    When we don't have a plan, it's easy to spend summer moving from bed to the computer. So it is necessary to make a work or study plan, like learning a new skill or working at a job.

    Because we don't have to go to school, it's easy to sleep late, watch too much TV and eat more snakes as usual. So it's necessary to make sure your summer days follow a schedule—getting up at the same time each day and eating meals as usual times.

    Whenever you're free, find something special to do, like making a dinner for your family. But remember: limit your screen time, no more than two hours a day.

    If it's too hot outside or you don't like going to a gym, you can do you exercise indoors. If you love being outdoors, try swimming, running or playing soccer in the early morning or evening. Anyway, don't let the heat stop your exercise plans.

    A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. {#blank#}3{#/blank#}He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. {#blank#}4{#/blank#}

    When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(减压病). The bends can cause a diver to double up in pain. {#blank#}5{#/blank#}

C. They can even kill him.
