However, many places are complete unimaginable Some places attract people more than others. The incapability to understand the real story behind some of these phenomena draws many people. They are just so mysterious that there is no explaining it. 1.Blood Falls, Antarctica How is it that the coldest and driest place on the planet has a blood-red waterfall pouring down slowly into the McMurdo Dry Valleys, some of the most extreme desert lands on Earth? What causes the mysterious flow was only recently "discovered" in a study. Scientists believed for many years red algae gave the unusual color. But now research has shown that iron oxide is responsible for the hue. The waterfall even contains strange bacterial lifeforms. 2.Magnetic Hill, Moncton, New Brunswick Be very careful if you choose to drive to the bottom of this hill. Stories about what happens there have been around since early 1900s. As impossible as it sounds, your car will start to "roll" uphill. "And it doesn't just work on cars--vans, trucks and even tour buses roll upward in total defiance of natural law," according to Tourism New Brunswick. 3.Racetrack Playa, Death Valley, California Located in a remote valley between the Cottonwood and Last Chance Ranges, Racetrack Playa is a place of really beauty and mystery. The Racetrack is a dry lakebed, best known for its strange moving rocks. It looks like they "sailed" through the valley. Although no one has actually seen the rocks move, the long moving tracks left behind in the mud surface of the Playa prove their activity. The most logical explanation so far is that ice forms covering the stones, causing them to move. Question: What will happen if you drive your car at the bottom of Magnetic Hill, Moncton, New Brunswick? - The car will run in unusual way. - The car will run down the hill. - The car will run backward. - The car won't work at all.

Q: Read the following article and select the best answer. Article: Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood. Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear. This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert. Question: Land becomes desert after all trees are cut down because _ . - roots of trees break up the soil - there are too many rainfalls - strong winds bring a lot of sand - there are no longer trees to keep the rain and protect the top-soil.
A: roots of trees break up the soil

Read the following article and select the best answer. Article: Dear Amy, My husband is a loving, creative and sensitive person who is 15 years my senior. (I am in my mid-30s.) Now I still struggle with my ups and downs, and he is still broke. I have continually asked my husband to get a job. I know he's trying, but even a part-time job at a convenience store would make ends meet. His former profession as a freelance producer dropped off with the economy, and while he tries hard to find work in his field, he is extremely unwilling to accept the fact that he may need to get a "regular"job. I love him very much, but I can't continue to keep my frustration bottled up. I tell myself I'm going to leave him if he doesn't find work, but I really want to stay together. How should I handle this? Round the Bend Dear Round, Having been a freelancer for many years, I assure you (and him) that the true meaning of freelancing is that you have the freedom to accept a variety of jobs, as well as the responsibility to make a living between jobs. Freelancers teach, tend bar, sell things door to door and do anything it takes to bring home the money. Volunteering is also a wonderful way to keep busy and meet new people. Amy Dear Amy, "Joan" was a 50-year-old reader who wants to spend her parents' gift (money) on a trip to India. Her retirement fund is less than half of what she will need for retirement. It's also clear that she hasn't budgeted monthly for car repairs and other out-of-pocket expenses. In your answer, you encourage her to go. She's 50 and the clock is ticking! How will she feel about the trip she took when she turns 70 when she can't afford to retire? Maybe there are other ways she can experience Indian food, culture, history and art without spending the entire sum of money. When her "health slows her down." she may wish she had kept a rainy-day fund. Realistic Reader Dear Realistic, Your argument is very logical and realistic, but there are also times when you have to go for it. I hope she does. Amy Question: Amy suggested Joan _ . - go for her dream of traveling to India - experience Indian culture at home - save money for retirement - refuse her parents' gift money
