Text 2 While fossil fuels—coal，oil，gas—still generate roughly 85 percent of the world’s energy supply,it's clearer than ever that the future belongs to renewable sources such as wind and solar.The move to renewables is picking up momentum around the world：They now account for more than half of new power sources going on line.Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources.But increasingly the story is about the plummeting prices of renewables，especially wind and solar.The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.In many parts of the world renewable energy is already a principal energy source.In Scotland，for example，wind turbines provide enough electricity to power 95 percent of homes.While the rest of the world takes the lead，notably China and Europe，the United States is also seeing a remarkable shift.In March，for the first time，wind and solar power accounted for more than 10 percent of the power generated in the US，reported the US Energy Information Administration.President Trump has underlined fossil fuels—especially coal—as the path to economic growth.In a recent speech in Iowa，he dismissed wind power as an unreliable energy source.But that message did not play well with many in Iowa，where wind turbines dot the fields and provide 36 percent of the state’s electricity generation—and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.The question“what happens when the wind doesn’t blow or the sun doesn’t shine?”has provided a quick put-down for skeptics.But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.The advance is driven in part by vehicle manufacturers，who are placing big bets on battery-powered electric vehicles.Although electric cars are still a rarity on roads now,this massive investment could change the picture rapidly in coming years.While there’s a long way to go，the trend lines for renewables are spiking.The pace of change in energy sources appears to be speeding up—perhaps just in time to have a meaningful effect in slowing climate change.What Washington does—or doesn’t do—to promote alternative energy may mean less and less at a time of a global shift in thought.
It can be learned that in Iowa,_____

A.wind is a widely used energy source
B.wind energy has replaced fossil fuels
C.tech giants are investing in clean energy
D.there is a shortage of clean energy supply

Green Energy

1.Green energy is energy that is produced in a manner that has, less of a negative impact to the environment than energy sources like fossil fuels,which are often produced with harmful side effects."Greener" types of energy that often come to mind are solar,wind,geothermal and hydro energy.There are several more,even including nuclear energy,that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.
2.The goal of green energy is generally to create power with as little pollution as possible produced as a by-product. Every form of energy collection will result in some pollution,but those that are green are known to cause less than those that are not. Most people who advocate greener sources of energy claim that the result of worldwide use of green energy will result in the ability to preserve the planet for a longer time.Greenhouse gases,a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming,or the process of the Earth heating up at an accelerated pace.
3.It is not completely necessary for green energy sources to come from places like solar or wind fields,which are examples of green"power plants".A green energy source can be a building that is designed in a way that it keeps itself cool in the daytime and heated in the night through its architectural design rather than having an air-conditioning or a heating system. The conservation of energy through architectural（建筑学的）design becomes, itself, a green energy source. Similarly, many sources of green energy can come directly from the area in which the energy is needed rather than from an outside source.
4.One of the goals of green energy technology is to take existing fossil fuel energy technology and clean it up so it is produced more cleanly. One such case is that of clean coal technology,where scientists are trying to find ways to extract energy from coal and other fossil fuels without all of the harmful side effects.The success of such these types of green energy depend upon the ability to extract harmful by-products from fossil fuels while not only being energy efficient,but by being cost efficient as well.

Greenhouse gases are thought to be causing______.
A:global warming
B:carbon emission
C:lower waste output
D:a green energy source
E:fossil fuels
F: clean fuels

Passage Four
How can we get rid of garbage?Do we have enough energy sources to meet our future energy needs?
These are two important questions that many people are asking today．Some people think that man might be able to solve both problems at the same time,They suggest using garbage as an energy source,and at the same time it can save the land to hold garbage．
For a long time,people buried garbage or dumped it on empty land．Now,empty land is scarce．But more and more garbage is produced each year．However,garbage can be a good fuel to use．The things in garbage do not look like coal,petroleum,or natural gas;but they are chemically similar to these fossil fuels．As we use up our fossil-fuel supplies,we might be able to use garbage as an energy source．Burning garbage is not a new idea．Some cities in Europe and the United States have been burning garbage for years．The heat that is produced by burning garbage is used to boil water．The steam that is produced is used to make electricity or to heat nearby,buildings．In Paris,France,some power plants burn almost 2 million metric tons of the cities garbage each year．The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil．
Our fossil fuel supplies are limited．Burning garbage might be one kind of energy source that we can use to help meet our energy needs．This method could also reduce the amount if garbage piling up on the earth．

According to the passage,using garbage is______

A.for heating in France each year
B.a new way in a modern society
C.a good way to solve the problem of energy shortage
D.too expensive as an energy source
