Article: As many people hit middle age, they often start to notice that their memory and mental attention are not what they used to be. We suddenly can't remember where we put the keys just a moment ago, or an old friend's name, or the name of an old band we used to love. It happens to most of us, but is it unavoidable? Scientists are increasingly showing that there's actually a lot that can be done. It turns that the brain needs exercise in much the same way as our muscles do, and the right mental workouts can improve our basic cognitive  functions. Now, a new San Francisco Web-based company has taken it a step further and developed the first "brain training program" designed to actually help people improve and regain their mental sharpness. Called Lumosity, it was designed by some of the leading experts from Stanford University. Lumosity is far more than an online place to exercise your mental skills. That's because they have combined these exercises with a Web-based program that allows you to systematically improve your memory and attention skills. Apparently it works. One study showed students improved their scores on math tests by 34 percent after using Lumosity for six weeks, greater gains than those made by other students in the same class, who were not training with the Lumosity program. The company says its users have reported clearer and quicker thinking, improved memory for names, numbers, directions, increased alertness  and awareness, high mood, and better concentration at work or while driving. 
 Answer: To improve students' scores on test.
answer:
What is the purpose of Lumosity?

Article: No one can change the weather. Nobody can control the weather. But if we read correctly the signs around us, we can tell what the more important changes in the weather will be. This way of telling what the weather will be like on the following day or two is called weather forecasting . For many centuries and in all countries, people have studied the weather and tried to make weather forecasting. Rings around the sun are a sign of coming rain. That many people feel their joints  hurt is a sign of wet weather. Some birds fly high if fine weather is coming, but they fly near the ground if rainy or stormy weather is on the way. If you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. Such rainbows come in the evening. If the stars twinkle clearly at night, then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset is mostly red in colour, then the following day will be fine. If a rainbow appears in the morning, rainy weather will probably come. Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting. 
 Answer: Weather forecasting is a way of telling what the weather will be like.
answer:
Which is true about weather forecasting?

Lan Yujie, professor at Anhui University of Technology, regards Mu and Zhang as good examples of choosing "what I like" instead of " what is practical" in finding jobs and seeking further study.
