Lots of heat from the sun and a shortage of water are just a few of the challenges facing desert animals. Deserts are homes to many animals and plants. Few large animals have got used to life in the desert because their size makes it difficult to find shelter from the heat and they can't store water. In order to survive, desert animals have developed a number of ways to live in their special habitat. The most common way is staying under plants or rocks or digging underground in the heat of the day. And many desert animals stay in shelter during the day and hunt at night when it is cool. Some animals get the water they need from the insects, plants and seeds they eat, and do not need to drink. They do not have sweat glands and pass only small amount of waste water. Some animals develop their own ways of surviving in deserts. The Thorny Devil is a kind of lizard that lives in Australian desert areas. It has a body that channels raindrops directly into its mouth when it rains. Water-holding frogs spend most of the year underground in Australian desert areas, and develop a sort of cocoon that enables them to store water to keep them going through the dry times. When it rains, they come out to lay their eggs in ponds. The eggs hatch within days and develop quickly, before the water dries out. Question: Which of the following is not a source of water to some desert animals? Options: A: Insects B: Seeds C: Plants D: Sweat
D

Read the article and select the best answer. Article: As the railroads and the highways shaped the American West in the past centuries, a new electrical generating and transmission system for the 21st century will leave a lasting mark on the West, for better or worse. Much of the real significance of railroads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around. The 19 th century saw land grants offered to railroad companies to build the transcontinental railroads, leaving public land in between privately owned land. In much of the West, some of the railroad sections were developed while others remained undeveloped, and in both cases the landownership has presented unique challenges to land management. With the completion of the interstate highway system, many of the small towns, which sprang up as railway stops and developed well, have lost their lifeblood and died. Big solar plants and their power lines will also have effects far beyond their direct footprint in the West. This is not an argument against building them. We need alternative energy badly, and to really take advantage of it we need to be able to move electricity around far more readily than we can now. So trade-offs will have to be made. Some scenic spots will be sacrificed. Some species will be forced to move, or will be carefully moved to special accommodations. Deals will be struck to reduce the immediate effects. The lasting effects of these trade-offs are another matter. The 21st century development of the American West as an ideal place for alternative energy is going to throw off a lot of power and money in the region. There are chances for that power and money to do a lot of good. But it is just as likely that they will be spent wastefully and will leave new problems behind, just like the railroads and the highways. The money set aside in negotiated trade-offs and the institutions that control it will shape... Question: What was the problem caused by the construction of the railways? Options: A: Small towns along the railways became abandoned. B: Land in the West was hard to manage. C: Some railroad stops remained underused. D: Land grants went into private hands.

Read the article and select the best answer. Article: Sarah Outland's weeklong "staycation" gave her a chance to explore her new surroundings after moving to Chicago. A day after moving to the Windy City last year, Outland started a new job and never got a chance to explore her new surroundings. After nine months as a resident, she finally took a week off work to visit famous landmarks, museums and shopping centers that were right under her nose. If you glance through a newspaper or listen to a news broadcast recently, you may hear or spot a strange word, "staycation". Staycation is a new word the American press is employing to describe a vacation very close to your home, or simply staying at home during your vacation. It is a combination of words "stay"and "vacation". According to many news reports, these staycations are achieving great popularity among American families this year. When asked about the reason for their expected staycation, respondents stated "gas prices are too high" (61 percent), "travel in general is too expensive (44 percent). The high price of gas for cars and airplanes has made it very expensive for Americans to travel compared to past years. When you combine this with the weak American dollar, it all adds up to people deciding to stay close to home during their traditional summer vacations. For aggressive young Americans who are trying to balance family and work, a staycation can be a great concept. They want to enjoy their homes and the attractions in their area without the stress of packing or making reservation. They won't be paying high fuel prices either directly, at the pump, or indirectly, in airfare, other than the gas required to drive around town. Absolutely, it's friendlier on the environment when locals take trips to attractions in their own area, and not everyone is game for a vacation that involves staying on a hotel compound. Few people live close enough to a real destination to make this worth their while. Question: Staycations are popular with American people mainly due to _ . Options: A: high traveling expenses B: stress of packing C: relatively low income D: lack of real destinations.
