    The day will come when renewable energy such as wind, solar, geothermal and others replace fossil fuels as the major source of world energy. However, most analysts insist that this day will not arrive for many decades to come—certainly well past the middle of the century. Systems of fossil fuels have already been firmly set up, and it is too costly or impractical to replace the existing systems with renewables. But there are good reasons to believe that the transition (转变) to renewables will come much faster than previously thought.

    It is hardly surprising that many experts say we will see a relatively slow transition from fossil fuels to renewables, given what is known about previous energy changes of this sort. "Energy transitions take a long time," observed Vaclav Smil of the University of Manitoba in Scientific American. It took more than 50 years for coal to replace wood as the world's leading source of energy and another 50 years for oil to replace coal; the change from fossil fuels to renewables, he argued, is not likely to come any faster.

    Under ordinary circumstances, Smil's forecast would no doubt prove accurate. But these are not ordinary times. Growing concern over climate change is leading to increasingly strict controls on CO2 and other greenhouse gas (GHG) emissions (排放), while the development in renewables technology is lowering their price and speeding their installation.

    There are, of course, many difficulties in the effective control of carbon emissions, as demonstrated by coal companies to block the introduction of new rules by the US Environmental Protection Agency. Nevertheless, it is impossible to dismiss the progress being made at the local and international levels to promote the use of renewables. The European Union (E. U), for example, is well on the way to achieving a 20% reduction in GHG emissions from 1990 levels by 2020, along with a 20% increase in the use of renewable energy.

    The transition to renewables will be faster due to dramatic improvements in the pricing and performance of such systems. As a result of the steady increases in the efficiency of wind and solar systems, together with the savings achieved through large-scale manufacture, the price of renewables is falling globally. With prices dropping this fast, solar energy is now proving competitive with fossil fuels for generating electricity in many areas.

    The change from fossil fuels to renewable energy will not come overnight, and it will not escape many setbacks. Nevertheless, renewables are likely to replace fossil fuels as the main source of electrical power well before mid-century.

(1)、Vaclav Smil believes that ________.
A、renewable energies are not very practical B、the change to renewables will come slowly C、systems of fossil fuels have been firmly set up D、there are many setbacks of renewable energies
(2)、We can learn from the passage that European Union ________.
A、has cut down half of the carbon emissions B、has failed to find a way to reduce GHG emissions C、is trying their best to encourage the use of renewables D、tries to stop the introduction of new rules on renewables
(3)、The renewables are more competitive because of ________.
A、their falling prices B、the decline in coal industry C、international trade D、the new rules on CO2 emission
(4)、The author writes this passage in order to ________.
A、call on people to use less fossil fuels B、give advice on how to promote renewables C、argue that the energy transition will come sooner D、prove the renewables will be the major source of energy

Grandparents Answer a Call

    As a third generation native of Brownsville, Texas, Mildred Garza never planned to move away. Even when her daughter and son asked her to move to San Antonio to help with their children, she politely refused. Only after a year of friendly discussion did Ms. Garza finally say yes. That was four years ago. Today all three generations regard the move as a success, giving them a closer relationship than they would have had in separate cities.

    No statistics(数据) show the number of grandparents like Garza who are moving closer to adult children and grandchildren. Yet there are evidence showing that the trend(趋势) is growing. Even President Obama's mother-in-law, Marian Robinson, has agreed to leave Chicago and move into the White House to help care for her granddaughters. According to a study by grandparents. com, 83% of the people say Mrs. Robinson's decision will influence grandparents in the American family. Two-thirds believe more families will follow the example of Obama's family.

    “In the 1960s we were all a little wild and couldn't wait to get away from home far enough or fast enough to prove we could do it on our own,” says Christine Crosby, publisher of Grand, a magazine for grandparents. “We now realize how important family is and how important it is to be near them, especially when you're raising children.”

    Moving is not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices(奉献), but sometimes it is wiser to say no and visit frequently instead. Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder.

    It has long been thought that elephants rely on their large ears and bathing in rivers to stay cool in hot climates. New research, however, has showed that the world's largest land animals have a secret trick of controlling their body temperatures.

    Scientists have long been puzzled by temperature regulation(调节)in elephants. Generally, animals with large bodies tend to hold more heat because, compared to their size, they have a small surface area for heat to escape from. Elephants, with their heavy­weight frames, would appear to be at a disadvantage in the heat of their African and Asian habitats, especially because they have thick fur to protect them from bushes and trees.

    Scientists thought that these creatures, which weigh up to 13 tons when fully­grown, grow large ears to help them stay cool. The skin on the ears is thinner, so blood which flows into them cools down more easily. But findings by researchers at two universities in Vienna have showed that elephants are also able to cool down by increasing the blood flow to skin patches(斑) in other parts of their bodies.

    The researchers studied six African elephants at Vienna Zoo as they moved between outdoor and indoor environments to see how the temperature on their skin surface would change. They found up to 15 “hot spots” all over an elephant's body surface, in addition to large patches on the ears. The study shows how these patches expand as the air temperature increases and more blood flows nearer to the skin surface. Other experiments show that elephants in the wild use the same “windows” to control their body temperature.

    Elephants have two additional ways to stay cool: flapping(拍打)the ears and bathing. Together with these tricks, the skin hot spots allow the animals to keep their body temperature always at about 36 degrees—one degree less than humans'.

    It was the night before my election. I was running for Sophomore Vice President.

    I had prepared a performance for the election--a funny boxing match. The fight had popular moves as seen in Dodge Ball, Iron Man, and Super Smash Brothers. In the end, I would perform my famous move, the Power-Punch from Hot Rod.

    My friend Cheyenne and I rehearsed (排练) the fight for hours, but the fight would not be a fight without music and sound effects. This is where my brother came in. He stayed up all night to work on that soundtrack. And when my computer's disk burner (刻录机) went out at 6 in the morning, he spent a college student's week's worth of incomes to replace it.

    Why would he go into all that trouble? Because he knew that out of all the other important things he could be doing, this was imperative to me. He knew because it was once important to him. Having graduated from Layton High just a year earlier, he knew what it was like to be in the center of people's attention. He knew how fun high school could be, and he wanted me to have a great experience.

    I ended up losing the election, but that day changed my world forever. The lesson my brother taught me became my most important belief. But it wasn't until I had a similar opportunity that I really understood why he cared so much.

    What did it take for me to understand? It was the performance. The rest of the cast and I would rehearse every day after school for 6 months all for what? The chance to perform a play eight times. As I came out on that stage for the first time and listened to the laughter, I was filled with joy. By the end of the play, the audience broke into tears, and so did we. What happened? We had the sweet opportunity of giving them an unforgettable theatre moment -- a moment to laugh, reflect, and shed tears.
