Why is 2004 a special year? Because it is a Leap Year（闰年）! What's so special about that? Well, Leap Year happens only once every four years. And it has 366 days instead of the usual 365. In a Leap Year, we have 29 days in February, while in a usual year we have only 28 days.

　　Why do we have a Leap Year? We have a Leap Year so we can keep the calendar（日历）in step with the seasons. The calendar is a kind of clock for the whole year. But how long is a year? A calendar year is 365 days. However, a true year is actually 365 days, 5 hours, 48 minutes and 46 seconds long. That's the time it takes the earth to travel around the sun. So every four years we have one more day, and we put it at the end of February, the shortest month of a year. Then we have a Leap Year.

Do you often think of your parents? You may say, “Of course, I  1 . I buy a present for my mother on Mother’s Day and on Father’s Day I give my father  2 ,too.” But what about the other days of the year?

I have a friend whose parents live in another city. One day I went to see her. We had a nice conversation . Then she wanted to  3 . So she dialed(拨号)the number, but then she put down the phone. After about fifteen  4 , she dialed the number again “Hi, Mom.”

Later I asked."  5  did you dial the number twice?” She smiled. “My parents are old and  6  . They can’t get close to the telephone quickly. I always do so when I call them. I just want to give them   7 time to answer the call.”

My friend is a good girl. She is  8  thinking about her parents. You also want to be a   9 child. Right? Please always remember to  10 your parents in every situation, not just on some important days.

Everyone wants to have healthy teeth. When you laugh, you will   1    your mouth and show your teeth. The healthier your teeth are, the happier you feel. Why is that?

Brush your teeth   4    a day, after getting up and before bedtime. And you brush all of your teeth, not just the front ones. Spend some time   5    the teeth along the sides and in the back. Take your time while brushing. Spend at least three   6     each time you brush. Be sure your toothbrush is soft. Ask your parents to help you get a new toothbrush   7    three months. Clean between your teeth with dental floss(牙线).It feels strange when you do it   8    first, but soon you'll get used to doing it. Brushing   9    your teeth healthy. You also need to care about what you eat and drink. Eat    10  fruits and vegetables and drink water instead of drinks.
