7.Wouldn't it be great if you could just look up at the sky and read the weather forecast right away?
Well,you CAN.The forecast is written in clouds.If you can read that writing,you can tell something about the atmosphere.With some practice,you can become a pretty good weather forecaster.Who knows,you might even do as well as meteorologists (气象学家).
Meteorologists use much more information than just the appearance of the clouds to make their forecast.They collect data from all over the world.Then they put it into powerful,high-speed computers.
This does give meteorologists an advantage,because they can track weather patterns as they move from west to east across the country.
But you have an advantage,too.You have your brains.You can look at the sky and get your data directly.A meteorologist uses a computer forecast that's several hours old to make a local forecast.
What are you seeing when you look at a cloud?"A picture of what moisture (水气) is doing in the atmosphere,"says meteorologist Peter Leavit.There's moisture throughout the atmosphere.Most of the time you don't see it,because it's in the form of an invisible gas called water vapor.
    Sometimes,the temperature of the air gets cold enough to cause the water vapor to change to liquid water.That's called condensation,and we see it happen all the time,for example,when humid air from the shower hits the cold glass of a mirror.When enough water vapor condenses,droplets form in the air.These droplets scatter light.A cloud is seen.
Watching clouds over a day or two tells you a lot more than a single cloud about the weather to come.Changes in clouds show changes in the atmosphere.
You should begin to notice patterns.Certain clouds,fol1owing each other in order,can signal an approaching storm.But don't take our word for it; see for yourself.
53.According to the passage,ordinary people can tell the weather becauseD.
A.they can look up at the sky                         
B.they can read weather writings
C.information is stored in computers              
D.clouds signal the weather to come
54.Your advantage in weather forecast is thatC.
A.you can keep weather patterns in mind.
B.you have more powerful computers at home
C.your brain works as well as a high-speed computer
D.meteorologists give their data to you as soon as they get them
55.A cloud is formed whenA.
A.there are droplets in the air                        
B.light is scattered
C.moisture exists in the form of invisible gas  
D.water vapor changes to liquid water
56.This passage mainly tells us about howD.
A.to become a weather forecaster                   
B.to collect data directly
C.to be an assistant to a meteorologist             
D.to keep an eye on the weather.

8.It was 3:30 in the morning and 8-year-old Walt Disney was doing what he did at that time every morning-rolling hundreds of newspapers he would soon deliver in his neighborhood.

5.People living more than three thousand meters above sea level find it difficult to raise vegetables all year long.People living in the highlands of Peru and Bolivia,for example,cannot grow vegetables outdoors during the months of May through September.It is very cold in the highlands at that time of year.If traditional farming methods are used,vegetables will not survive.
However,there is another way to grow vegetables throughout the year in cold areas.It is a method of gardening developed by a private agency called World Neighbors.The method uses"hot houses"built below ground.A hot house is a building covered with plastic or glass in which vegetables or flowers are grown.The traditional hot house is built above ground.
The air temperature is cold in the highlands of Peru and Bolivia during the winter.But,the winter sun is hot.So,World Neighbors advises farmers there to build hot houses below ground.The design is simple.The material does not cost much.Here is how World Neighbors says to build it:Dig a hole two and one-half meters wide and six meters long.Make it about two meters deep.Build wall with a door in one end of the hole.Dig steps from the ground down to the door.
Now,build a wall along the top edge of the hole.Make it about one-half meters tall.Earth bricks work fine.Build two shorter walls on the ends.These will be uneven; one side will be as high as the existing wall.The other side will be at ground level.Leave a small opening in each of these sloping walls.This prevents the hot house from becoming too hot.Now,make the roof.Build a wood frame.Cover it with clear plastic.Connect it to the brick walls.
The underground hot house we have described is large enough for two raised vegetable beds.Each is one meter wide and six meters long.Each is seeded and watered just as if it were in a garden above ground.
The dirt walls protect the growing plants from the cold.The clear plastic roof permits the sun's heat to enter.At night,the roof should be covered with straw.This helps prevent cold air from entering.An under ground hot house this size will provide enough vegetables for one family.Groups needing more vegetables can make it bigger.

66.If you lived in Peru,youC.
A.should raise the special kinds of vegetables that can endure cold
B.could not plant at all
C.had to work out some new unusual plans
D.would not have many vegetables to eat
67.To our surprise,the"hot houses"invented by World Neighbors areB.
A.covered with a transparent plastic ceiling
B.built under ground
C.quite small
D.hotter than traditional ones
68.The hot house can be kept warm by usingD.
A.a big oven
B.an electricity heater
C.the heat of the earth's interior
D.the sun shine
69.The measure to prevent the hot house from becoming too hot is toB.
A.make the roof sloped
B.dig holes on the walls
C.make the wall not vertical
D.make the walls shorter than the ground level
70.According to the passage,the method suggested by World Neighbors isD.
A.new and difficult     B.uneasy to explain
C.at trial step         D.simple and practical.

12.The way we cook is important.In many countries,the two sources of heat used for cooking are nat-ural gas or electric stoves.The World Health Organization (WHO) warns that millions of people are dying every year from indoor air pollution.The WHO finds that poor cooking,heating and lighting technologies are killing millions of people each year.
     Indoor air pollution results from the use of dangerous fuels and cook stoves in the home.WHO of-ficials say nearly three billion people are unable to use clean fuels and technologies for cooking,heat-ing and lighting.And they say more than seven million people die from exposure to indoor or outdoor air pollution each year.Of that number,the WHO says about 4.3 million people die from household air pollution given off by simple biomass(生物燃料 ) and coal stoves.
       These findings show that the home use of poisonous fuels is to blame for many of these deaths.
 These fuels inrlude wood,coal,animal waste and so on.Carlos Dora is Coordinator in the WHO's De-partment of Public Health,Environmental and Social Determinants of Health.He says people should  not use unprocessed coal and kerosene (煤油 ) fuel indoors.He says opening a window or door to let out the harmful air will not correct the situation.It will only pollute the outdoors."New technologies  and clean fuels can rid people of this problem."
         The United Nations found that more than 95 percent of families in suh-Saharan Africa depend on  solid fuels for cooking.It says huge populations in India,China and Latin American countries,such as Cuatemala and Peru,are also at risk.
         Nigel Bruce is a professor of Public Health at the University of Liverpool.He says researchers are developing good stoves and other equipment to bum fuels in a more efficient way."There are already many technologies for clean fuels available now.An effective and reasonably low-cost ethanol(酒精)stove that is made by Dometic (a Sweden-based company) is now being tested out.Another interesting development is electric induction stoves."In India,you can buy an induction (屯磁) stove for about 8.AndinAfricayoucanbuyasolarlampforlessthan1.
25.According to Carlos Dora,what is the best solution to indoor air pollution?B
A.People should use an effective air cleaner.
B.People should use new technologies and clean fuels.

A.By listing numbers.
B.By following time order.
C.By describing a process.
D.By making classifications.
27.What can we learn from the passage?A
A.Burning solid fuels can help limit indoor air pollution.
B.People can buy ethanol stoves made by Dometic in India.
C.There are already two technologies for clean fuels available for use.
D.Most of the deaths from indoor pollution are in developing countries.
28.Which would be the best title for the passage?D
A.The Way We Cook Is Changing
