It is reported that 300 million people in China have eyesight(视力) trouble. More and more parents hope to improve their children's eyesight with medicine, or by correcting the ways that children read and sit. But in fact, one should start with the exercise on one's feet. Here are three ways to improve eyesight.
First, don't tie your shoes too closely. Try wearing comfortable and soft socks or walking without socks and shoes at home. While you are traveling, try wearing cloth shoes in order to improve blood circulation (循环).
Second, walking on tiptoes is good for one's eyesight. It can fight against eyesight trouble. Numbers show that most of ballet(芭蕾舞) performers' eyesight is better.
Third, rope skipping(跳绳) can also be good for one's eyesight. While skipping rope, one has to move quickly, making both the brain and the eyes excited. It may also help make one grow taller.
Besides foot exercises, it is good to pull one's ears. Pulling the ears 20 times quickly is also a great way. It can keep one's eyes healthy.

Turn on the radio. A program will come out from a broadcasting station miles and miles away. We know that sounds and music themselves couldn’t travel that distance through space .There must be something that brings the program from the station. But what is this silent carrier ( 载体) ?
This is known as radio waves. However, we can’t see them or even hear them. In fact, nobody knows exactly what they are. Nevertheless( 然而) ，we know that they are made by electricity .
At the broadcasting station, people talk, sing, play musical instruments or make many other sounds. These sounds are changed into electricity. Then from the broadcasting aerial (天线)of a tall tower , electricity sends out radio waves which travel in all directions .And some of them reach your radio aerial. What happens next is a magical thing. The radio waves start an electric current ( 电流) in your aerial like the one that was first made in the broadcasting station . Finally, the loudspeaker in your radio set changes the electricity into sound .Therefore, you hear the program.

Of course, that doesn’t matter to Ricky and Lucy. They have a habit that they must find a place to fight with each other no matter how cold or hot it is.
As cold as it was, I was excited thinking about how wonderful this special cold really was.
Then the sun broke through the clouds and memories of summer’s really hot days came through my mind. I could remember standing in heat of the afternoon, with sweat pouring down my head and the hot, burning sun against my face.
