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 （脈搏）．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．
Check your emotions．Getting angry easily？If you can't put your finger on a clear reason，there may be something wrong with your emotions．Hoping to change the condition won't help．The only way out is a break．
Check your weight．If you lose or increase more than 1% of body weight from one day to the next，something is wrong．Maybe yesterday you were too busy and failed to notice you didn't eat and drink enough．Or maybe you failed to notice that you were eating too much．

3．How do you make friends？Some students are sharing their ideas with us．

Tom Although we are quite different，Adam and I have been close friends for 5years．We have a lot to talk．We play basketball together after school．We go for a picnic at weekends．It's always a pleasure to be with him．	Yumi I spend my spare time mostly with people from other countries．When I'm with them，I really get to know what they're like and how easy they are to get along with．They help me to improve my English．
Anna I've made some good friends at the gym I go to．People there are very friendly．Talking to them as I take exercise is a good way for us to get to know each other．	Peter I can make more friends on the Internet because it keeps me in touch with the whole world．I can get worldwide stories from my friends all over the world．

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）．

66．In the first paragraph，the underlined word"it"refers toB．
A．The hot air over the water   
B．The cool air over the earth
C．The hot air over the earth   
D．The cool air over the water
67．Now scientists knowA．

B．Everything about the ocean．
C．What happens to the salt in the ocean．
D．Why the ocean does not get more saltier．

D．Both B and C
69．Which of the following is NOT mentioned in this passage？D

B．The reason why the ocean doesn't get saltier every year．
C．The reason why the water in the ocean is salty．
D．The reason why rocks crack．
70．The main idea of this passage is thatB．
A．people feel cool when they are near a lake or an ocean．
B．scientists can explain many things，but not everything．
C．scientists can explain everything about the ocean．
D．the salt in the ocean comes from rocks．

1．Many people are surprised when they find that the Internet was set up in the 1960s．At that time，computers were large and expensive．Computer networks didn't work well．If one computer in the network broke down，then the whole network stopped．So a few network system had to be set up．It should be good enough to be used by many different computers．If part of the network was not working，information could be sent through another part．In this way computer network system would keep on working all the time．
At first the Internet was only used by the government，but in the early 1970s，universities，hospitals and banks were allowed to use it，too．However，computers were still very expensive and the Internet was difficult to use．By the start of 1990s，computers became cheaper and easier to use．Scientists had also developed software that made"surfing"the Internet easier．
Today it is easy to get online and it is said that millions of people use the Internet every day．Sending e-mails is more and more popular among young people．The Internet has now become one of the most important parts of people's life．

20．That day，I felt the world seemed wrong and I came to the park．The park bench（長(zhǎng)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（可憐的） 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 （點(diǎn)頭）．
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（多皺的） 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（殘忍的） 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

17．Thang-ga（唐卡） is a special kind of painting，It was found only in Tibet．China It started from the dynasty （唐朝）．Thang-ga  paintings show Tibetan people's lives．In recent years，Thang-ga paintings have caught the public's attention．At the same time，the Chinese government has also tried hard to protect the art．
The colors of Thang-ga paintings look wonderful and special Because of the special environment of Tibet and the excellent skills of artists，the paints （顏料）used in Thang-ga paintings are different from other paints．They were made from minerals like gold and silver，as well as some plants．The paints were made by hand and the beautiful colors could last （持續(xù)）for hundreds of years
However，with the development of technology，people now use cheaper and easily-made chemicals to make Thang-ga paints．The traditional paints used in Thang-ga paintings took a lot of work and they were made in many secret ways．Later people stopped making the paints and forgot about them．So the skills needed to make them were almost lost．The traditional Thang-ga paintings are difficult to find now．

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 （新陳代謝速度）can make you uncomfortable．You may feel dizzy （眩暈的）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(chǎn) 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．
