Global Warming is a term used to descri be an increase in the average sur face temperature of the
Ear th over a period of time . I t can refer to past periods of warming ,such as occurred about 15,000
years ago , towards the end of the last ice Age , but i t is usually used to mean the change in the climate
that it i s thought l ikely will occur as a resul t of thegreenhouse effect, as explained below .
The present average sur face temperature of the Earth i s about 15 C ( 59 F ) and this vari es by few
tenths of a degree each year . Over longer periods of time , the Earths surface has been both cooler
(perhaps about 11 C or 12 C (between 52 F and 54 F ) dur ing the Ice Age , or glacial ) and warmer
( perhaps about 16 C (61 F ) dur ing some per iods between the I ce Ages-the interglacials ) .Over
the past 100 years or so , the average surface temperature has increased by about 0.5 C (1 F)
The most probable explanation for the present global warming is that i t is the resul t of increasing
concentr ations in the atmosphere ofgreenhouse gasessuch as carbon dioxide , methane , and
chlorofluorocarbonswhich all ow energy from the Sun to reach the Earth , but prevent some of i t
from escaping back into space . These gases have been steadily building up for over 100 years , largely
as a result of mankinds use of fossil fuels , such as coal and petroleum , to provide energy . Since we
wil l almost certainl y continue to rely on fossil fuels as our main source of energy for many years to
come , and since the Earths population is expected to have doubled by the year 2100 , the
concentr ations of greenhouse gases wil l continue to rise thr oughout the next centur y . It is estimated
that global warming wil l i ncrease the average sur face temperature of the Ear th by between 1C and
2 C( 2 F and 4 F ) by the year 2100.
1. Which is the best definition for global warming ?
1) An increase in the average surface temperature of the earth over a period of time.
2) The change in the climate that happens as the Earth grows older .
3) A collection of different climates around the world .4) The past periods of warming about15,000years ago, towards the end of the last Ice Age .

Speed is important in tr ansporting f ish and many other f resh foods . Food that spoil easi ly must
reach the market and the dinner table as quickly as possible . But now planes , trucks, trains ,
and ships have made thi s transportati on easier . Planes are the fastest way to tr ansport food .
They are especial ly useful in carrying food to people and animals that could not be reached by
trains or trucks . Unless packages of food could be dropped by planes , the people might starve .But there is a disadvantage in using planes : air transportation is usuall y the most expensive way
of carrying f ood . And so with in a country most perishable foods are transported by trucks and
trains .

3) nobody would suffer from lack of food

3) can be quickly spoiled 4) are normally canned

Reading 4 ( azad tajrobi 91 )
BPA is a chemical that put into plastic that are used as food containers . Unfortunately , some of the
BPA passes from the containers into the foods that they are meant to protect . When people and
animals eat those foods , BPA goes into their bodies . There are studies that have found that BPA canincrease our chances of getting a number of serious disease . Many food companies are concerned
about that risk and are starti ng to use containers that contain no BPA.
Thats good right ? Not necessarily . Some scientists say that the other chemicals being used might
tur n out to be dangerous as well . They could possibly be even worse !
1. According to this article ,BPA .1) leaks into food 2) is used to make food taste better2) means Better Plastic Articles 4) makes us strong
2. Food companies are starting to . .1) charge more for BPA2) tell people not to worry about PBA3) use containers that do not contain BPA4) tell that they dont use BPA in their containers
3. Some of the new food containers .1)look more colorful
2)might have chemicals that are dangerous
3) have extra BPA at no additional charge
4) leak all over shelves
4. The underlined word concerned is closest meaning to .1)sorry 2) worried 3) pleased 4) ashamed
5. The final paragraph of the article makes the point that . 1)there is no such thing as a safe food container
2) BPA might really be good for us
3) its best to just stop eating
4) change does not always mean improvement

Reading Five : ( e . s . 92 )
To obtain power from the suns rays is to use nuclear power developed at no expense in a
laboratory 93 million miles away . For the bright energy of the sun is maintained by nuclear
transformation of chemical elements occurring in the suns interior at temperatures of many
million degrees , and at pressures of many million atmospheres . The resources of solar power are
enormous . If 100 percent efficiently could be secured in the transformation of radiant solar energy
into mechanical work , a horsepower per square yard of ground surface would be available under
cloudless skies . The expense of collecting solar energy still prevents its competition with the usual
power sources . Yet , unless the vague promise of safe thermonuclear power from oceans becomes
realized , solar power must supply the enormous and growing requirements of children within two
centuries . Because the ground sources ( coal , oil and uranium ) may be used up soon , they will
become more costly than solar power .
1.According to the reading , what do we need to convert sunrays to energy ?
1.Thermonuclear power sources . 2.A constant resource of chemicals .
3.A laboratory millions mile away . 4.A cloudless sky at temperatures of enormous degrees .
2.Which of the following is the best topic for the reading ?
1.solar energy : an impossible energy source 2.Solar energy : facts and realities
3.Expenses of using solar energy 4.Different sources of energy
3.According to the reading , an alternative to solar energy can be .. .
1.ocean thermonuclear power 2.energy from fossils
3.radiant energy 4.nuclear power
4.The writer points out that solar energy is not used on a large scale.
1.though it is clean and safe
2.because the expense of controlling it is enormous
3.because it can create some dangers to the environment
4.since it is costly and less costeffective than other sources of energy
