9.What will the house of the future look like?Could it have gardens on its walls,or a pool with fish for dinner?Architects believe that they are all possibilities.The only thing for sure is that the houses will be as green as possible.
The tree house
  Many architects in the world would like to build a"tree house."Like a leaf,the surface of the house collects sunlight during the day.The energy can be used to heat water,produce electricity,and even create fresh air for the home.The"root"(根) of the house is deep under the ground.It uses the soil (土壤) to the home's temperature.
The Lizard house
   Like a lizard (蜥蜴),changing color with the weather is the most important design of a lizard house.When it's in the bright sun,the cover of the house will turn dark to protect it from strong heat.During dark days,it turns white and takes in as much light and heat as possible to produce energy.
Meals at home
  This design is perhaps as much about the future of food production as architecture (建筑風格).It has gardens on the outside wall of the house.People can plant tomatoes,carrots and green tea on them.So every day in the morning,you just need to walk outside and collect your meals.
Learning from the past
   Looking to the future isn't the only way to be green.Sometimes,ancient techniques (古老的技術(shù)) can also help cut down energy use.For example,a chimney (煙囪) can be a useful air conditioner because it is easier of hot air to flow out at the chimney.

40.What is the best title (標題) of the passage?A
A.Green house of the future.
b.The greener,the better.

A.with the root of a leaf.
B.with the energy from sunlight.
C.with the soil under the ground
D.with gardens on its walls.
42.What will happen to the cover of the lizard house when it's in the bright sun?C
A.It will take in light.
b.It will produce energy.
C.It will turn dark.
D.It will turn white.
43.The passage seems to tell us that meals at home in the futureD.
A.will be more delicious.
b.need more cooks.
C.cost as much as possible.
D.will be greener.

9.Up to 65% of children don't get as much sleep as they should do,and this can make them nervous and slower at school,scientists say.
So how long should young people sleep each night?The answer is between eight and ten hours.If you don't get enough sleep at night,you'll have less energy the next day.
But the scientists say many children have missed out on 4,500 hours of sleep by the time they are seven years old.They say that children miss sleep because they have TVs and computers in their rooms,and busy parents don't read to their younger children at night any more.The traditional"bedtime story"helps children to relax and fall asleep peacefully.Children with TVs and computers in their bedrooms were more likely to sleep badly,and to get less than eight hours'sleep.Even losing one hour's sleep a night can mean that children do less well at school.
German scientists think that your brain (大腦) keeps working while you are asleep.To show that they were right,they gave two groups of people a problem to work out.One group went to sleep,and the other group stayed awake.The result?The people who slept worked out the answer more quickly.
This showed that their brains had been trying to find the answer while the people were asleep.So,make sure you get enough sleep tonight,and you'll be at your best tonight,and you'll be at your best tomorrow!
56.What problem do more than a half of students have?C
A.They don't get on well with their studies.

C.They don't have enough sleep at night.
57.If you have less energy the next day,you'll probably feelBat school.

B.slow and nervous
C.a(chǎn)lone and angry
58.According to the third paragraph,what has worst influenced many children's sleep?B
