2．For better eyesight（视力），doctors advise limiting（限制） the hours of screen time and encourage having enough eye resting time．
However，another study shows that sitting in front of computer or TV screens for long hours is not the only reason for myopia（近视）．An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia．The research team found that there were less children who had myopia in Sydney than those in Singapore，even though they spent more time in front of computer and TV screens．The major finding is that children in Sydney spend longer hours on outdoor sports than those in Singapore．
Indoor and outdoor sports both make the eyes pay attention to more distant（远处的） objects，which stops the eyes from changing original shape．But outdoor sports may be better than indoor sports for myopia．Because natural light is good for eye growth and vitamin（维他命） D from the sunlight might be useful to it．Many doctors suggest that every child get its first eye test when he/she is about two and half years old，and even if his/her sight seems good enough．It is necessary for myopic（近视的） children to wear glasses to stop headaches，trouble reading and so on．It is also important that schools invite doctors to test their students'eyes．
If that is not possible，school teachers should at least encourage parents and children to have regular eye examination and wear glasses．And parents should remember not only to limit the total screen time for their children，but also to encourage them to spend time outdoors．

71．What did the Australian research team study for？A．
A．To find the reasons for myopia．
B．To find the ways to treat myopia．
C．To learn to choose right glasses．
D．To improve children's eyesight．
72．Why are there fewer children with myopia in Sydney than those in Singapore？D．
A．Because the children in Sydney watch TV less．
B．Because the children in Sydney have more eye resting time．
C．Because the children in Sydney use computer less．
D．Because the children in Sydney do more outdoor sports．
73．What is good for eye growth according to the passage？C．
A．Natural light．B．Vitamin D．
C．Natural light and Vitamin D．D．The sun．
74．Which of the following is true？B．
A．Children should have eye tests as soon as they reach school age．
B．Looking more at distant objects can help the eyes keep their original shape．
C．Doing outdoor sports with no glasses is good for myopic children．
D．Children should limit their time in the sun to protect their eyes．
75．The passage mainly tells usC．
A．the children in Sydney spend more time in front of screens
B．the children in Singapore like outdoor sports
C．doing outdoor sports and limiting the hours of screen time are good for eyes
D．it's important to test students'eyes．

8．Feeling left out？
A reader wrote in to say that she was feeling lonely at break because her best friend wasn't around．Here's our advice to her-and to all kids who feel lonely sometimes．
It's hard when a best friend isn't around-maybe because she moved to a different school or a different class．You may feel lonely at break or lunchtime．You want to have new friends．but how do you make them？Maybe it seems like everybody else already has their friends．But remember，there's always room for more friends…
Start by looking around your classroom-think about which kids you'd like to play with at break．Look for chances to say hi to them，smile，and be friendly．Offer to share something or express your appreciation（欣赏）to them．Invite someone to play with you or say"Do you want to sit here？"in the lunchroom．When you're at break，walk over to kids you want to play with，act friendly，and say"Hi，can I play，too？"or just join in．
If you have trouble doing this or if you're feeling shy，ask your teacher to help you make  new friends．Teachers are usually pretty good at matching up friends．The best way to make friends is to be a friend．Be kind，be friendly，share，say nice things，offer to help-and pretty soon，you'll have one，or two，or even more new friends．
You might still miss that special best friend．But when you see each other，you can share
something you didn't have before she left：You can introduce her to your new friends!

5．A 5R Rule for Environment
1．Reduce（减少）
If you want to reduce waste，you should use things wisely．A large number of trees are being cut down to make paper．If everyone uses a little paper carelessly and throw it out，soon we would not have any trees left．Other things are also being wasted，and people don't know what to do with the waste in big cities．So it is necessary to reduce the waste．
2．Reuse（再利用）
You should always think of reusing the usable things before throwing them out．Give your clothes you do not use or the ones which are too small to the poor．In a family，you may pass on such clothes to younger brothers or sisters．
3．Recycle（回收）
Bottles，cans and paper can easily be recycled．By doing so we save lots of time and money．For example，coke cans are sent to a factory，where they are smashed（打碎） flat and melted（融化） and the metal things are made for new coke cans．
4．Recover （恢复）
When you buy a box of apples，there may be a few rotten apples，you have two choices：one is to throw the whole apples away，or you could cut off the rotten parts and use the good parts．In this way，you are recovering the eatable parts of food．
5．Repair（修补）
If one of the legs of your table is broken，you can repair it．If you want to change for better ones，it is better for you to sell the old things or give them to other people who can use them after doing some repair．It is true that North America is a"throw-away"society，but the time has come to change our way of life so that we can protect our environment．Every one of us should try our best．

66．The"Reduce"rule mainly requires（要求） usA．
A．to use things wisely
B．to cut down many trees
C．to use less paper
67．The right order of recycling coke cans isB．
a．collect the used cans   b．melt them   c．smash them flat  d．send them to a factory
A．a b c d
B．a d c b
C．d b c a
68．The"Recover"rule mainly requires usC．
A．to throw thing away
B．to cover waste thing with the earth
C．to get back the useful parts
69．B is the best way to do with your broken tables．
A．Throwing them away
B．Repairing them
C．Putting them away
70．According to the passage，C can not be reused．
A．clothes
B．shoes
