In the atmosphere , carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun’s rays to enter but prevents the heat from escaping.
According to a weather expert’s prediction, the atmosphere will be 3 ℃ warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several meters and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球), possibly resulting in an alteration of the earth’s chief food growing zones.
In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.
Satellite pictures show that large areas of Antarctic ice are already disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warms the earth
However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling. Scientists conclude, therefore, that up to now natural influences on the weather have gone beyond those caused by man. The question is: Which natural cause has most effect on the weather?
One possibility is the variable behavior of the sun. Astronomers at one research station have studied the hot sports and ‘cold” spots( that is, the relatively less hot spots) on the sun. As the sun rotates(使旋转), every 27.5 days, it presents hotter or colder faces to the earth, and different aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earth’s atmospheric pressure, and consequently on wind circulation. The sun is also changeable over a long term: its heat output goes up and down in cycles, the latest trend being downward.
Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering a new Ice Age and it is hot. One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(惯性) of the earth’s climate. If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun’s fading heat.
It can be concluded that concentration of carbon dioxide in the atmosphere would ____.
A. mean a warming-up in the Arctic.
B. raise the temperature of the earth’s surface.
C. prevent the sun’s rays from reaching the earth’ s surface.
D. explain the cause of great changes in the climate in the northern hemisphere.
The article was written to explain____.
A. the greenhouse effect. B. the solar effects on the earth.
C. the causes affecting weather. D. the models of solar weather of solar weather interactions.
Although the fuel consumption is greater in the northern hemisphere, temperature there seems to be falling. This is ____.
A. mainly because the levels of carbon dioxide are rising
B. partly due to changes in the output of solar energy
C. possibly because the ice caps in the poles are melting
D. only due to the effect of the inertia of the earth’s climate
On the basis of their models, scientists are of the opinion that .
A. the climate of the world should be becoming cooler
B. the new Ice Age will be delayed by the greenhouse effect
C. the man-made warning effect helps to increase the solar effects
D. it will take thousands of years for the interia of the earth’s climate to take effect.
If the assumption about the delay of a new Ice Age is correct, ___.
A. ice would soon cover the northern hemisphere.
B. the greenhouse effect could work in favor of the earth.
C. the best way to overcome the cooling effect would be to burn more fuels.
D. the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly.

Hundreds of students from around the world gathered in New York City last week for the Microsoft Imagine Cup finals. They came to present their ideas for using technology to solve world problems.
Microsoft education director Suzi Levine says the nine-year-old program began mainly as a competition to create technology.
SUZI LEVINE: "When we realized that students really actually want to have a purpose for what they're creating, we introduced the idea of inspiring them with the UN Millennium Development Goals and suggesting that they use those for their muse(灵感). "This past year we also rolled out something called the Imagine Cup Solve This library（创新杯求解计划知识库）, where IGOs, NGOs and nonprofits can submit some of the technical challenges that they would like students to consider for their solutions."
Microsoft says over 350，000 high school and college students registered for this year's competition. Judges chose more than four hundred of them to attend the finals.
SUZI LEVINE: "One from Thailand was called NewKrean, where they created a Windows Phone 7 application that allows you to broadcast your location to your social network of friends so that you can be more easily rescued." They named their application Terra.
Suzi Levine says there were also ideas from Egypt inspired by the revolution that overthrew president Hosni Mubarak in February.
SUZI LEVINE: "One was to use Bluetooth as sort of a Twitter equivalent so that if the government shuts down the Internet, you actually can still have a massive social distribution."
Students competed in nine categories. For example, in software design the top prize of twenty-five thousand dollars went to Team Hermes from Ireland. The students developed a device for cars to collect information on road conditions, driving behavior and traffic incidents.
A team from Taiwan's National Tsing Hua University won first place in the embedded（内嵌的） development category. They developed a network of wireless devices to help plot the safest escape routes during a fire.
Next year's awards ceremony will take place in Australia. Registration for Imagine Cup twenty-twelve opened Friday. Also, Microsoft announced plans for a three million dollar program to help Imagine Cup winners further develop their projects.

As rain begins to fall from the clouds, it is very pure. However, as it falls through the air it dissolves some of the gases in the air ,It also collects bits of dust and microbes(微生物)that are floating in the air, When the rain reaches the ground it begins to pick up more dust and dirt, Many kinds of mineral substances dissolve in the water ,Sand and nud cannot dissolve in water.
Since water is so important to us, it is very important that the water we use should be clean , Otherwise, we might get some of the diseases that are carried by water Many microbes are harmful ,They are so small that we cannot see them ,These microbes must be removed or killed before the water is not clean, people who drink this water may get these diseases, Thus , to provide people with clean water, the government purifies the water.
Purification is a long process and consists of three stages: storing ,purifying and distributing ,The first stage is storing , Man-made lakes called reservoirs are used for this purpose ,Water from the rains ,other lakes, streams and rivers is collected in the reservoirs ,This water is usually dirty and muddy.
In the second stage shich is purifying , water from the reservoirs is filtered in a special pond, Stones, sand and other unwanted tiny things are caught in it, After that, tiny microbes are still present in the water ,These microbes are removed by “airing ”the water and by adding a chemical substance called chloring(氯)to the water ,This kills all the microbes in the water ,A fter this the water can be safely used for drinking.
The third stage is the distribution of the purified water to homes ,hospitals, offices ,factories and other places, This is done through a network of pipes of various sizes, These pipes must be make of a suitable material.

Environmental health is defined as the control of the factors (因素) in the environment that may have harmful effects on people’s physical, mental, or social well-being (安乐). Because natural disasters expose people to danger by bringing up or threatening their immediate environment, effective management of environmental health after a natural disaster is of great importance.
The environmental health measures that must be considered after a natural disaster include the supply of appropriate shelter for individuals or groups of people left homeless, the distribution (分配) of safe and accessible water, and the protection and distribution of safe food products and so on.
To effectively manage environmental health during and after a disaster, it is important that a state of preparation is in effect before the event actually occurs. During an emergency, success largely depends on making good, rapid judgment and appropriate response measures. High-level decision makers, therefore, must be familiar with sound measures beforehand and should be given an accurate judgment of the disaster’s specific effects as quickly as possible.
This book is intended to serve as a guide for those who may be called upon to make emergency decisions after disaster strikes. The recommended environmental health measures have been listed in the order of priority in which they should be taken during an emergency. However, each natural disaster is unique in the degree or type of emergency. In response to any given disaster, decision makers may find it necessary to change the priority assigned to any particular measure.
1.The first paragraph is mainly to _____.
|
A．tell the reader how to understand environmental health |
|
B．express why environmental health after a natural disaster is important |
|
C．describe the terrible scene that is caused by the natural disasters |
|
D．give advice on how to deal with the management of environmental health |
2.In order to effectively cope with the emergency, the most important is that _____.
|
A．we should have enough shelters and tools |
|
B．everyone should be familiar with the situation |
|
C．we should be well prepared for it in advance |
|
D．we can deal with it just as we did before |
3.We can’t do just as the recommended environmental health measures because _____.
|
A．some of the measures have not been taken before |
|
B．they are not the same according to different degrees or types of emergency |
|
C．they are probably made up by someone without experience |
|
D．they can’t be changed once they are taken by the experts |
4.The best title of this passage should be _____.
|
A．Environmental Health Management after Natural Disasters |
|
B．The Bad Influence of the Natural Disasters |
|
C．Useful Measures to Avoid the Natural Disasters |
|
D．The Importance of the Environmental Health Management |
