At the beginning of this century, medical scientists made an interesting discovery（发现）: we are built not just of flesh (肌肉) and blood but also of time. They were able to show that we all have a ‘body clock’ us, which controls the and fall of our body energies. It can us different from one day to the next.
The idea of a ‘body clock’ should not be too because the lives of most living things are controlled by the 24-hour night-and-day cycle (循环). We feel and fall asleep at night. We become and energetic during the day. Most people will have a bad feeling if the 24-hour cycle is . For example, people who are not used to working at night can find that lack (缺少) of sleep causes them to badly at work.
the daily cycle of sleeping and waking,we also have other cycle which lasts longer than one day.Most of us would that we feel good on some days and not so good on others;sometimes our ideas seems to be so active and at other times,they are not.

I have always wanted to share this story because it is one of the things that I will remember for my whole life. And I’m sure the other person feels the same.
We had a new teacher in my middle school World History class. She was very nice and excited to see us. She told a story about her fighting in a war and brought a picture of him. After about fifteen of her talking, the class started talking softly to each other they were getting bored. Looking , she asked “So, you guys don’t really want to hear any more?” No one dared to say “no” to her loud one kid. He said, “No, not really!” a disrespectful(无礼的) way. Some kids were a little and thought that it was rather rude.
I felt really bad for this teacher. No one should be in such a disrespectful manner. Therefore, near the end of the class I went up and said to her for the guy’s rude behavior. I told her I had been listening, and even though I may not really like , I was grateful to her for sharing her story. I asked her about her father and asked to see the picture of him. We had a very nice, sincere conversation about her father.
The teacher was touched. She thanked me for coming up and actually treating her with the respect(尊敬) that she deserved. I felt at full peace with knowing that I did the right thing and I was super happy that I made her day. Even though I didn’t really care for history, I listened, and I hope that others in different situations will do the same. Listening means a lot to the people sharing; it really . If I had just left the class without saying a word, I would have felt very and would have a constant reminder, probably to this day, that justice(公义) was not served and I had left a person in their time of need.

The children of migrant workers who have remained in their hometowns while their parents work in the cities are known the "left-behind children" in China.
During the summer vacation, a lot of these children travel afar, often to a remote city and only for a short visit to see their . But meeting their parents doesn't mean these children are going to enjoy a enjoyable summer . Many of their parents are migrant workers who spend all day building houses or selling vegetables on the market.
Most of these children are aged between 6 and 12, so leaving them home alone is not a safe choice.
And sending the left-behind children to the summer camp or taking them to amusement parks may a lot of money, so even when these children visit their beloved parents, of them just spend the holiday watching TV or going to the library. Also, many parents choose to take their children with them even when they are working.
Going to a summer school where they can have a safe place to either study or play is a good choice for migrant worker parents it saves money. , many of the summer schools are already too crowded because the number of children of migrant workers is too . And more summer schools for children of migrant workers are needed.

When I was nine years old, I used to go to the post office with my mother, sending greeting cards to my aunt in Singapore. To me, these trips were really memories. And receiving mail through a mailbox outside our gate was just exciting. My small hands could get the mail without using a key! I always couldn’t wait to see how much I was . Oh, a letter! From Singapore! I would run back home and show it to my . When there was a letter for me, I wouldn’t run—I would open it right there.
After my family moved back to Singapore, I going to the post office. Years later, my company sent me to Shanghai, and the post office found me again. Two years ago I celebrated my with five friends on top of the mountain in Longsheng, China. At sunrise we up to a beautiful view from the mountain top. Later in the afternoon, as we were going the mountain and returning from the sunrise viewing place, a shop caught our attention. It only sold noodles, coffee and had a China sign.
We asked the owner if she could really send mail. She happily said yes. It seemed hard to believe we were at the highest top of the mountain. I picked one postcard out and asked my friends to write a birthday note. We bought a stamp, wrote some notes and gave the shop owner the postcard.
Three weeks later, I arrived home and my mailbox: Hello, postcard! I broke into a big smile.
That birthday postcard attracted me again to the post office and all its delights. I had the post office all these years. Today I send postcards to friends. And every time I am at the post office buying stamps, I cannot help but smile—how one postcard will make its way across the world and brighten up someone’s day.
