12.In winter,when the sun hides behind the clouds,everyone feels a bit low.You may be tired and find you want to sleep all the time.What you may not know is:you are suffering from (患有) SAD(季節(jié)性抑郁癥).
But don't worry-it's normal.Colder temperatures and fewer hours of daylight can steal your energy and put you in a bad mood.

19.How much do you know about the bird world?
Birds use three gaits:walking,running and hopping.
In walking,the left and the right feet move in turn(輪流).Each foot is on the ground for more than half the time,so there are more times when both feet are on the ground.In running,each foot is on the ground for less than half the time,and there are more times when both feet are off the ground.In hopping,the feet move almost at the same time.This means that for much of the time both feet are off the ground.
Middle-sized and large birds walk at low speed and either run or hop at higher speed.Small birds,such as sparrows and swallows,usually do not walk,because walking may be too slow for them.It seems that the more time a bird spends in trees,the more likely it is to hop.Perhaps there is wide space in a tree between one thin branch(樹枝) and the next,so walking is not a good choice,while on each small branch there is enough room to set both feet down side by side,so hopping seems to make sense.

根據(jù)短文內(nèi)容,選擇最佳答案,并在答題卡上將選定的答案標號涂黑.

7.The Australian government researchers did research on the eyesight and habits of 100seven-year-old children in Singapore and Australia.The research shows that sunlight is good for people's eyes.If you spend two or three hours playing outdoors each day,it is not easy for you to become short-sighted.
    Both groups spent a similar amount of time reading,watching TV and playing computer games.However,the Australian children spent an average(平均)of two hours a day outdoors-90minutes more than the Singaporean children.As a result 30% of the Singaporean children were short-sighted-this rate(比率)was ten times higher than Australian children.
    Dr.Ian Morgan said,"Humans are naturally long-sighted,but when people begin to go to school and spend little or no time outdoors,the number of short-sighted people gets larger.We're also seeing more and more short-sighted children in cities all around the world-and the main reason may be that city children spend less time outdoors."
    Daylight can be hundreds of times brighter than indoor light.But why does playing outside stop us from becoming short-sighted?Scientists believe that natural light has a special chemical(化學物質(zhì)).It can stops the eyeball from growing out of shape and stop people becoming short-sighted.
    So be outdoors.It doesn't matter if that time is spent having a picnic or playing sports.
66.The researchers did research onB of the children in two countries.
A.habits and foodB.eyesight and habits C.eyesight and food D.eyesight and studies

A.food B.studies C.indoor light D.sunlight
68.According to the second paragraph,the Singapore children spend an average ofA outdoors a day.
A.30minutes B.90minutes C.1hour D.2hours
69.What is the fourth paragraph mainly about?C
A.Why people become short-sighted.
B.Why natural light has a special chemical.
C.Why playing outside is good for one's eyesight.
D.Why sunlight is much brighter than indoor light.
70.From the passage,we learn thatB.
A.children in Australia are more likely to become short-sighted than those in Singapore.
B.children in the city are more likely to become short-sighted than those in the countryside.
C.people won't become short-sighted if they stay indoors every day.
D.people will all become short-sighted after they begin to go to school.

17.(1)Sweden's program of producing genergy from rubbish is so successful,but recently its success has also produced a surprising problem:There is simply not enough rubbish in this country.It has been reported that only 4% of their rubbish goes into landfills(垃圾填埋場). The rest 96% is recycled or more recently being re-used as fuel(燃料)in their waste-to-energy factories that are able to deal with up to 2 million tons of rubbish every year.And this situation has made Sweden face the serious and special problem mentioned above.
(2)Sweden has recently begun buying much waste every year from other countries,such as Norway,Bulgaria,Romaniaand Italy.These countries depend heavily on landfills.In the United States,where 250 million tons of rubbish was produced in 2010 alone,only about 34% was recycled.As a result,more than half of their waste ends up in landfills.
(3)Sweden is now paid by Norway to take its waste away.Sweden not only gets money from other countries but also changes the waste into energy in Sweden,which provides electricity and heating for so many homes.It's a win-win situation.Clever!

4.Healthy eating doesn't just mean what you eat,but how you eat.Here is some advice on healthy eating.
Eat with others.It can help you to see others'healthy eating habits.If you usually eat with your parents,you will find that the food you eat is more delicious.
Listen to your body.Ask yourself if you are really hungry.Have a glass of water to see if you are thirsty-sometimes you are just thirsty,you need no food.Stop eating before you feel full.
Eat breakfast.Breakfast is the most important meal of the day.After you don't eat for the past ten hours,your body needs food to get you going.You will be smarter after eating breakfast.
