Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age. Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25. The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time. Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here's where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles -- making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles -- so it appeared to be smaller than the real smaller orange circle. When young children aged 4 to 6 looked at these tricky pictures, they weren't fooled -- they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time. As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they're more likely to fall for this kind of visual trick. When asked to find the larger circle, _ . A) children at 6 got it wrong 79 % of the time with no gray ones around B) only adults over 18 got it right 95% of the time with gray ones around C) children at 4 got it right about 79 % of the time with gray ones around D) adults got it right most of the time with gray ones around

The food on the moon has come a long way from the freeze - dried bread to half - dried food. They have changed a lot in the past few years. And now US scientists want to grow vegetables in mini - greenhouses on the moon. Scientists say they are looking forward to a time when people on the moon or even Mars will be able to eat green and fresh vegetables. Paragon Space Development Corporation has shown people what it called the first step toward growing flowers - and finally food - on the moon. Paragon, which is a partner of NASA in experiments at the International Space Station, calls it a "Lunar Oasis " This is a closed greenhouse placed in a metal box. It is designed to safely land a laboratory plant on the moon surface, and protect it while it grows. The small greenhouse is to be sent up into space by Odyssey Moon Ltd, which takes part in the Google Lunar X Prize. This competition offers $ 20 million to any company which can send up, land and operate a lunar rover on the moon surface. Leaders of Paragon say future testing of the "Lunar Oasis" will be driven by Odyssey's flight schedule, which will not happen until 2012 at the earliest. When it is sent up, the greenhouse will have the seeds of cabbage inside it. Because they go from seed to flower in just 14 days, they can complete their life cycle in a lunar night. "Growing plants on the Moon or Mars seems so far away, but it is important that we do this research now," Paragon president Jane Poynter said. "It takes a long time to do a lot of research." What would be the best title for the passage? A) Exploring the Moon and the Mars B) Making Use of the Lunar Rover C) Researching Fresh Food on the Moon D) Seeking the Living Things on the Moon

Ques: Here are a few tips to help you, the workaholic, re-focus and get the best out of life. EIGHT HOURS OF SLEEP! Make it a point to get at least eight hours of sleep and plenty of rest. Don't believe that you can always "catch some sleep or rest later." Your body cannot make up for lost sleep or rest time because it is not physiologically possible. STRICTLY FAMILY ON WEEKENDS! Resolve to make Saturdays and Sundays strictly for family time. And stick to this! Mondays until Fridays you make an excuse not to relax and spend time with your family because it's work time, why not make a similar excuse for Saturdays and Sundays? "I can't work today because I'm spending time with my family." GET SOME FOOD IN! Make sure you get food in your stomach. Workaholics are known to be food-skippers. If you can't afford to get off your desk or from doing paperwork, have food delivered to you. It's always a good idea if you have crackers on your drawer to ease the hunger pangs. CONFINE WORK! Resolve to _ work in your office. Don't bring work to your home! Keep those files in your office desk where they belong. Practice working only within your working hours. If you have an eight-to-five working schedule, stick to it. WORK UP THOSE MUSCLES! Exercise, exercise, exercise! Set aside at least an hour each day or every other day for exercise. You body needs to be conditioned, and working non-stop isn't going to give it the proper physical conditioning it needs. Since most workaholics tend to have their behinds stuck on their chairs, it's even more important that you get some exercise. MAKE A PLAN! Plan your day. Work on only one or two things at a time. It's much easier to work on something and finish it first and then move on to the next rather than do a number of things all at the same time and never finish or accomplish anything at the end of the day. Make out a list of priorities. Write down things that need to be worked on immediately or are urgent, keeping the least ones at the bottom of your list. After you've done this, be... By making a plan, the author mean _ . A) working on only one or two things each day B) finishing a number of things at once C) organizing your time and finishing urgent things first D) accomplishing as much work as possible at any given moment
