In the summer between my first year and second year in college，I was invited to be an instructor （辅导员）at a high school camp．On the first day，when we were dancing and playing games，I noticed a boy under the tree who was small and thin．His shyness made him appear weak．I walked towards him，introduced myself and invited him to join in the activities and meet some new people．He quietly replied，"No，I really don't want to do this．"I could understand that he was in a new world but I knew it wouldn't be right to force him，either．Actually，the boy didn't need a close talk but a friend．
At lunch the next day，I was leading camp songs when 1saw the boy under the tree sitting alone．I tried again with the same invitation，but he refused once again．That evening I was told the boy's name was Tommy．Then I asked the campers to pay special attention to the boy and spend time with him when they could．
The days went by and the time came when we had to leave．We held a big，warm party to celebrate the closing of the camp．All the campers shared their wonderful moments．To my surprise.1found the boy from under the tree dancing joyfully with two girls．I couldn't believe it was the same person．
In October of my second year，I received a phone call from Tommy's mother．She told me that Tommy was hit by a car and killed．I offered my deep sadness．The mother said："'Tommy mentioned you so many times．I want you to know that he went back to school and made new friends with confidence．You made a difference for Tommy during his last months．"
At that moment，I realized how easy it was to give a bit of yourself every day．You may never know how much each gesture may mean to someone else．I hope that everyone can pay attention to their own"boy under the tree"．

Zu Chongzhi was one of the greatest mathematicians（数学家） in ancient China.He was born during the Northern and Southern（1） （ dynasty）.From a young age，Zu was taught natural science，astronomy（天文学），math and so on.The little boy was （2） （ interest） in all of these subjects，especially in （3） .
Zu was best known for his calculation（计算） of pi （π）.According to the record，he did all the work using nothing but wooden sticks. （4） took him lots of time to work out the value —（5） 3.1415926 and 3.1415927.No one at that time was able to do better than Zu.And now the achievement is still praised by people around the world.In order to remember Zu，some mathematicians suggest （6） （call） pi"Zu Lv".
Zu was successful not only in math，but also in astronomy.He worked out that a year should be 365.24281481 days long and created the Daming Calendar. （7） ，government officials at that time did not agree with Zu.The great mathematician （8） saw his calendar put into use.Almost ten years after his （9） （die），the new calendar was finally accepted.
Zu was an inventor，too.He once made a vehicle（车辆） （10） carried a pointer （指针）.No matter how the vehicle turned，the pointer always pointed to the south.
Bicycle riding is good exercise.It helps people become （1）f .Bicycle riding can make the riders' hearts and lungs strong.It is also good for the environment because bicycles do not cause （2） （污染）.
Bicycles share the road with cars and trucks.Drivers do not always notice bicycles.So bicycle riders must （3）p attention to the traffic around them and know traffic signals.They must know and obey the safety （4）r .They must wear helmets to protect their heads.If they ride at night，they should have lights on the bicycle or wear light﹣colored clothes.In case of an accident，bicycle riders should know how to give first aid.If an injury is serious，they must call 120 for help.In a word，the best way to be safe is to be （5） （小心的）.
When we say "we threw something out，" what do we really mean？After all，our waste doesn't just disappear even if it is taken a（1） .So why not recycle it？
Have you ever used newspapers when you clean the windows？If you haven't，please try!I didn't believe it when I（2） （听到）and read that.I thought that they would certainly leave ink（墨汁）or bits of paper behind.Actually，I was so wrong.I have had clearer windows than before s（3） I tried it
When we mention cleaning products，we have to talk about paper towels（手巾）I used （4） to think more paper towels meant a cleaner home.I loved the idea of cleaning with the fresh white paper and then throwing（5） out.But now I know that I have to s（6） using paper towels，because paper towels are a huge waste problem.Cutting out paper towels would save（7） （树），water，air and our money.
Recently.my family and I have started collecting all old （8） （衣服），and then cut them into pieces.Getting one piece to do some cleaning has become our n（9） habit.I thought that it would be such（10） uneasy thing to break a 30﹣year old habit.Whatever，it really is the most meaningful thing that I have done during a long time.
