When you're returning to Australia, be careful that you don't bring in pests and diseases. Some items you might bring back from overseas can be pests and diseases that Australia doesn't have. When you return, declare all food, meat, fruits, plants, seeds, wooden souvenirs, animal or plant materials. Australia has strict quarantine laws and tough on-the-spot fines. Every piece of luggage is now screened or X-rayed. If you fail to declare any quarantine items, or if you make a false declaration, you will get caught. In addition to on-the-spot fines, you could be accused and fined more than $60, 000 and you may risk 10 years in prison. All international mail is also screened. Some products may require treatment to make them safe. Items that are restricted because of the risk of pests and diseases will be seized and destroyed by the Australian Quarantine and Inspection Service(AQIS). In many cases, the goods you declare will be returned to you after inspection. However, any item that presents a quarantine risk will be withheld . You will be given a range of options for each item depending on the quarantine risk: Treating the item to make it safe; Holding the item until an import permit is presented*; * Re-exporting the item; Destroying the item. Those treatments with the sign "*" are subject to fees. Further information: For more detailed information about bringing in food, animals, plants, animal or plant materials, call the AQIS at 1800-020-504. Which of the following don't you need to declare when returning to Australia? A) Tea. B) Wooden combs. C) Some bread. D) A pair of glasses.

Imagine putting some bacteria in the freezer and taking them out millions of years later to find that they are still alive. That would be similar to what happened recently, when scientists brought eight-million-year-old bacteria back to life -- simply by thawing them out. The ancient bacteria were found frozen in the world's oldest known tracts of ice, the glaciers of Antarctica. Professor Bidle and his colleagues found and revived two samples of bacteria from the glacial ice. The first was a hundred thousand years old, and the second was around eight million years old. The eight-million-year-old bacteria were alive. But their genes were seriously damaged from long exposure to cosmic ( ) radiation, which is higher at the earth's poles. Most of the bacteria in the samples probably blew over from African deserts, said Paul Falkowski, a scientist at prefix = st1 /RutgersUniversity. Once the bacteria landed on the glacier's snowy surface, they combined with the snow to form ice. "These ices are actually gene banks," he added. As glaciers and ice caps melt as a result of increasing global warming, large amounts of bacterial genetic material might be washed into the ocean. These bacteria might get incorporated into today's bacteria in the ocean, or living bacteria from the ice might also grow and have an important effect on the ecosystem. "How that's going to play out, we don't know," Bidle said. He and Falkowski plan to focus their future work on how current ice melting influences modem bacteria's genetic diversity. Professor Bidle found that the eight-million-year-old bacteria were _ . A) alive with their genes damaged B) as active as the one-hungred-thousand-year-old ones C) totally the same as what they used to be D) harder to revive than the one-hundred-thousand-year-old ones

Q: Hey there, So you're about to spend four years of your life and tens of thousands of dollars of your parents' money, and all you really know about college is that all of your friends are going. Do you ever stop to wonder why you're going? Relax. You're making the right decision. First of all, you'll discover what interests you by taking courses in many subjects. For example, it's hard to decide if you want to be a painter if you've never painted any pictures; once you're in a drawing-room on campus, you'll know one way or the other. College is also a lot of fun--after you graduate, you'll be working every weekday for 50 or so years. And remember that college graduates get about twice the of those who never attended college. Finding the right college can be difficult. Fortunately, is here to help you every step of the way. Researching School. To us, the most important decision you'll make is to choose the school that really fits you best---- not the one that is the most competitive or has the best-equipped rooms. Applying to School. On , you'll find hundreds of actual college applications and links to many more. Raising Your Scores. American College Test is one of the most important parts of the admissions course. It's not the most important, though, and not everyone needs to prepare for the best. But, if you think you can do better, find the right course for better scores. Paying for School. Most families need financial aid for the high cost of college. The problem is that financial aid seems difficult to get and many families get caught up in the price of college. However, if you really do your research, you'll learn that there are many ways to get financial aid and that you can afford to attend any college, no matter the cost. For more information, call 600-3681 or visit J , wherever you go, have a nice trip! Johnson Smith Founder and CEO John Review What does the author advise you to do to pay the high cost of college? A) To ask the family for help B) To make a study of financial courses C) To do research on the price of college D) To get to know how to ask for financial aid

Fast food advertisements greatly influence teens' eating habits and advertisers are increasingly targeting them with a wide range of promotions. Fast food advertisements significantly affect teens' eating habits, leading to consequences such as obesity. TV Advertising The television is the largest source of food ads to teens. It is worth noting that TV watching may not be the chief cause of obesity, but rather the fast food commercials. This implies that fast food commercials greatly influence teens' eating habits, since food is the most advertised item on television. Online Advertising The Internet has become part of a teen's daily life. Fast food manufacturers have taken advantage of this to target teenagers with food commercials. McDonald's corporation has created websites such as 365Black.com. which target minority groups. MeEncanta. com is a McDonald's website that targets Latino youth, who are four and a half times more likely than other youth to visit the site. Eating Habits There is a strong connection between teens' eating habits and fast food commercials. In a study of more than 12,000 teenagers to inquire into the effects of fast food advertising on teenagers, teens who spent more than two hours watching commercial TV were likely to allow themselves to eat more unhealthy foods like fast foods, sugary drinks and snacks than those who did not. Obesity Teens who view fast food ads are at a higher risk of becoming overweight than those who do not, reports the American Academy of Pediatrics. In a survey of 3,342 youths aged between 15 and 23 researchers found that a higher percentage of obese and overweight participants identified with fast food ads. What's the author's attitude to fast food advertisements? A) Objective. B) Favorable. C) Critical. D) Doubtful.
