Are you afraid of sharks? You shouldn't be! Below we cleared up the main _ about one of the world's most perfectly formed creatures ... All sharks are the same. This is ly not true. There are nearly four hundred species of sharks and they vary widely in habitat, size, features, diet and lifestyle. They range from the cigar shark, which is about 15 centimetres long, to the whale shark, which can be up to about nine meters long. More than 50 percent of sharks are less than a metre long and more than 90 percent are less than two metres long. And their habitat ranges from shallow to deep water and from the Arctic to the Tropic. _ This is not true, either. In fact, many shark populations are decreasing. The chief reason for this is that hundreds of thousands of them are caught in fishing nets. Depending on where they are caught. They are either killed for their fins , which are used in shark's fin soup, or they are tossed back into the sea because they are unwanted. Almost all sharks which are discarded in this way die. Also, sharks mature late in life and produce very few young. If the current reduction in numbers continues, the ecological balance of the oceans will be severely threatened. Sharks will always attack you This is nonsense. The chances of being attacked by a shark are minimal. You are 250 times more likely to be killed by lightning than by a shark, and your chances of being killed by lightning are practically zero. However, if you are planning to take a swim in shark territory, then follow these simple rules: Avoid swimming at dawn or duck when visibility decreases. Avoid areas where there are breaking waves. Turbulent water makes it difficult for sharks to see and determine whether you are prey . Do not wear jewellery in the water. Sharks are attracted to shiny fishes, and jewellery may resemble their scales . Do not swim near schools of small fish, which are the favorite food of some sharks. Which of the following rules should you follow when you're going to swim in shark areas? A) Don't swim before day breaks. B) Choose areas where there are big waves. C) Wear something shiny when swimming. D) Choose areas where there are many small fish.

Traffic jam and cities, it seems, go hand in hand. Everyone complains about being stuck in traffic; but, like the weather, no one seems to do anything about it. In particular, traffic engineers, transportation planners, and public officials responsible for transportation systems in large cities are frequently criticized for failing to solve traffic jam. But is traffic jam a sign of failure? Long queues at restaurants or theater box offices are seen as signs of success. Should transportation systems be viewed any differently? I think we should recognize that traffic jam is an unpreventable by-product of successful cities, and view the "traffic problem" in a different light. Cities exist because they promote social interactions and economic transactions.Traffic jam occurs where there are lots of people but limited spaces. Culturally and economically successful cities have the worst traffic problems, while _ cities don't have much traffic. New York and Los Angeles are America's most crowded cities. But if you want access to major brokerage houses , you will find them easier to reach in crowded New York than in any other large cities. And if your firm needs access to post-production film editors or satellite-guidance engineers, you will reach them more quickly through the crowded freeways of LA than through less crowded roads elsewhere. Despite traffic jam, a larger number and wider variety of social interactions and economic transactions can be made perfect in large, crowded cities than elsewhere. Seen in this sight, traffic jam is an unfortunate consequence of prosperity, not a cause of economic decline and urban decay. So while we can consider traffic jam as increasing costs on the areas of big cities, the costs of inaccessibility in uncrowded places are almost certainly greater. There is no doubt that traffic jam brings the terrible economic and environmental damage in places like Bangkok, Jakarta, and Lagos. But mobility is far higher and traffic jam levels are far lower here in the US, even in our most... According to this article, which statement about "New York" and "Los Angeles" is true? A) The traffic jam in the two cities has been worsened. B) New York and Los Angeles are the least successful cities in the US. C) It is easier to reach major brokerage houses in the two cities than in other cities. D) Despite the traffic jam in LA, you'll find a satellite-guidance engineer more quickly there.

A man enters a store to buy milk. He walks out of the store with milk. That is all-- milk. At the same time, a woman enters the same grocery store also to buy milk. She buys it. But, she also buys chicken and lemons to make dinner that night. Then she remembers to buy food for her son to eat at school. She also gets a bottle of wine for drinks with friends and a birthday card for her husband's niece. Then she gets coffee for breakfast, ice cream for dessert and remembers stamps to mail the bills. And don't forget soap for the bathroom. And that is the difference between the female and male brains simply explained in a grocery store. Generally speaking,men do one thing at a time. Women do many. Doing many things at one time is often called "multi-tasking", a very popular word these days. Now scientific research supports this theory about male and female brains. A recent study has confirmed what we have known all along--men and women think differently. Scientist at the university of Pennsylvania studied brain images of 949 people aged from 8 to 22 years old. They found that male brains have more connections on one side of the brain, or hemisphere. In female brain, they found more activity and connections between the right and left sides of the brain. The left side of the brain is known as the side of "reason" The right hemisphere is known as the "creative" side. Regina Verma is a professor at the University of Pennsylvania. She co-wrote the report. She says when women are asked to do something difficult they might use different parts of the brain. Men, she adds, generally use just one side of the brain. As a result, men generally deal directly with a problem. There is a strong connection between the "understanding" and the "action" parts of their brains. Women, however, might include other parts of the brain, like the part connected with reason and the part connected with sensitivity when solving a problem. Women take a less direct path to find a solution. Dr. Venma warns that the study should not lead anyone... When asked to deal with a problem, _ . A) men tend to take action straight B) women tend to take action straight C) women tend to use a single part of the brain D) men tend to use connected parts of the brain
