Question: Read the following article and select the best answer. Article: A rainfores is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16degC.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world .Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world. In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit . There are two main reasons for _ . Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world' s wood supply. Rainforests are often called the world's drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world's shrinking rainforests.

Question: Read the following article and select the best answer. Article: One important attraction of walking is its long-lasting appeal. Whereas jogging and aerobic dancing can _ quickly, walking provides a popular activity that seems to endure. Fitness foundations estimate that 35 million adult Americans walk for exercise every day, with at least 15 million walking two or three times a week. Among the most regular walkers are those 65 years and older--evidence that walking is an exercise that lasts. In addition to its many physical benefits, walking, like other physical activities, has a comforting effect on the psyche. Walking can help you to think more clearly and feel more relaxed. It also can be a sociable activity. An early morning walk around the neighborhood provides an opportunity to chat with friends or simply admire the flowers. Or because it does not require a team or even a partner, walking is something you can do on your own time, by yourself, whenever the mood strikes. Easily affordable, all you need to start walking is enthusiasm and a pair of comfortable and sturdy low-heeled shoes. Dr.ChristineL. Wells recommends an Oxford-style shoe with ties for better foot support; she does not recommend sneakers or other "cheapies". If you plan to walk regularly, you might want to invest in a pair of so-called walking shoes. If so, expect to spend at least $35. For walking during the hotter months, early morning or evening hours are best. Clothes should fit loosely and be lightweight and light-colored. Elderly walkers should consider wearing long sleeves, and all Arizonans need to be particularly concerned about skin cancer.

Wells advises drinking an 8-ounce glass of water before you start out, and more when you return.

Question: Read the following article and select the best answer. Article: To be successful in any aspect of life, you need to know when to use the carrot or the stick. Here are a few tips to help you decide whether it's better to use the carrot or the stick. With the kids The carrot When it comes to raising a kid, the carrot or the stick dilemma is quicklydisappearing as too many parents take the carrot approach to the extreme. In child raising, the carrot should never be materialistic things. If you want to ask for good behavior with a reward, it should be with something that can't be bought, say, trust. The stick Nowadays, no one likes to use the stick any more, or in my father's case, the belt. I'm not overlooking child abuse, if you ever want to call it that, but I am encouraging parents to toughen up a bit. You don't want your kid to test your limits only to find out he can get away with it. If you want to raise a kid, raise the hand and let him know it comes down on the second offense. At the office The carrot People need encouragement and motivation to perform well. However, the carrot only really works well with employees who have already proved themselves. Ifyou've got someone who can't show up at the office before noon, the promise of a raise isn't going to do much. On the contrary, if there's a guy with a good work moral, he'll thrive (grow stronger) when you add a promotion to the picture. The stick When considering the carrot or the stick in the office, remember that, overall, the stick is the more practical method in the office. A wise man, who just happened to be an Italian, once said "It's best to be both loved and feared." It's nice to have everyone love you, but running a business isn't like running a family. You need to have the stick constantly raised. With the wife The carrot When it comes to marriage, always use the carrot. I've had a lovely marriage for many years, and I've always stuck to the carrot approach. Sometimes you catch more flies with honey, and sometimes it's the crack of a whip that gets the horse moving. Try not to use too many sticks at home;...
