4．When you work long hours and Sundays are no longer a day to rest，feeling overworked can become the new normal．Take sportsmen as examples and do the same yourself，so you'll know if you're overworking．
Check your resting heart rate （率）．Every day，before you get out of bed，take your pulse （脉搏）．Usually your heart rate will stay within a few beats every minute．But when you're overworked，the rate increases．If your heart rate is up in the morning，get a little more rest or sleep that night．

2．When the weather is hot，you go to a lake or an ocean．When you are near a lake or an ocean，you feel cool．Why？The sun makes the earth hot，but it can not make the water hot．Though the air over the earth becomes hot，the air over the water stays cool．The hot air over the earth goes up，then the cool air over the water moves in and takes the place of the hot air．When you are near a lake or an ocean，you feel the cool air when it moves in．You feel the wind and the wind makes you cool．
Of course，scientists cannot answer all of our questions．If we ask"Why is the ocean full of salt？"scientists will say that the salt comes from rocks．When a rock gets very hot or very cool，it cracks （崩裂），and rain falls into the cracks．The rain then carries the salt into the earth and the rivers．The rivers carry the salt into the ocean．But then we ask"What happens to the salt in the ocean？The ocean does not get saltier every year．"scientists are not sure about the answer to the question．
We know a lot about our world．But there are still many answers that we do not have，and we are curious（好奇的）．

20．That day，I felt the world seemed wrong and I came to the park．The park bench（长凳） was free as I sat down．Just then a young boy out of breath ran towards me．He stood right before me with his head down and said with great excitement，"Look at what I found!"
In his hand was a flower，and what a pitiful（可怜的） sight，with its petals（花瓣） all worn-not enough rain，or too little light．Wanting him to take his dead flower and go off to play，I nodded （点头）．
But he sat next to me and smelt the flower．He said with surprise，"It surely smells pretty and it's beautiful，too．That's why I picked it．Here，it's for you．"
The flower before me was dying or dead．But I knew I must take it，or he might never leave．So I reached for the flower，and replied，"Just what I need．"
But instead of placing the flower in my hand，he held it in the air．It was then that I noticed for the first time that the boy could not see：he was blind．
I was very surprised．I thanked him for picking the best one．"You are welcome，"he smiled，and then ran off to play．
Through the eyes of a blind child，at last I could see the problem was not with the world but the problem was me．And for all of those times I myself had been blind．
And then I held that flower up to my nose and breathed in the smell of a beautiful rose．

19．Very often，newborn babies are not beautiful．They are wrinkled（多皱的） or hairless，or they have an angry look on their faces．They seem to say，"Get away!I hate everybody!"But to a parent，that hairless，wrinkled，angry-faced baby is the most beautiful and perfect child in the world．When that proud father or mother asks you，"Well，what do you think…isn't she beautiful？"What are you going to say？Is this the time for the truth？Of course not!You look at that proud father or mother in the eyes and say，"Yes，she is!She is really a beauty．She is going to be a movie star!She is as beautiful as a picture．"
In English，this is a white lie．White lies don't hurt people．They are not cruel（残忍的） or angry words．People use them to make a difficult thing a little easier．When people don't want to meet someone，or eat something new that they really don't like to eat at a friend's house，they tell a white lie．They are trying to be kind．They feel that being kind is sometimes more important．

18．Dear editor，
I am not a good-looking boy and I'm not good at studying，either．Some people don't even want to talk to me．So I usually feel lonely．Sometimes I think that if I wanted to leave home，nobody would care．How can I stop feeling like this？
Peter
Dear Peter，
Without knowing more about you，it is hard for me to give you some good advice．
But first，I am sure that you are wrong that nobody would care if you left home．What about your parents？And other family members？It seems that you are very sad．You'd better go to see a doctor or talk to your parents．They will be able to help you．
Secondly，I'm sure there is someone in your class who feels lonely，too．You never know how other people feel inside．Try to make friends with them．
Or you may join a club to meet new people and to keep yourself busy．
You need to find happiness in yourself．Write a list of all the good things about yourself，learn to like yourself，and then others will see your confidence and like you，too．
Editor

15．When we exercise hard，we burn fat （脂肪）．But have you ever wondered where exactly the fat goes？
Some doctors think that fat is changed into heat and given off in the air．Others think the body burns it．Some even joke that someone comes and takes it．That's why you always weigh less in the morning．
Now a new study from Australia solves the mystery．
"The correct answer is that most of the fat is breathed out as CO₂．It goes into thin air，"says the study．
Scientists followed the atoms （原子）in 10 kilograms of fat as they are lost．They found that 8.4 of those kilograms are breathed out as CO₂ through the lungs （肺）．The other weight，1.6 kilograms，bccomes water and leaves the body．
"None of this is easy to understand because we can't see the CO₂ we breathe out，said the study's lead expert．
Does that mean you can lose more weight by breathing more？It is not as easy as you think．Breathing more than the body's metabolic rate （新陈代谢速度）can make you uncomfortable．You may feel dizzy （眩晕的）and become unable to see，move or feel，according to the study．
So how can people lose weight healthily？The key is to eat less and move more．You may have heard this many times．During a day．a 70kg person breathes out about 200g of CO₂．So if the same person wants to lose weight，he or she can do some light exercise，for example，walking fast．This can help lose 24Og of CO₂．
