Are you preparing for a big test? If so, you may want to go play some basketball in between hitting the books. Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels（管）, including those in the brain, stronger and more fully developed. Dr. Cameron claims this allows people who exercise to concentrate better. As she says, "While we already know that exercise is good for the heart, exercise can really cause physical changes in the brain."
The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. With babies, even a little movement can show big results. Margaret Barnes, a pediatrician（儿科医生）, believes in the importance of exercise. She thinks that many learning disabilities that children have in elementary school or high school can be traced back to（可追溯到） a lack of movement as babies. "Babies need movement that stimulates their five senses（感官）. They need to establish a connection between motion（动作）and memory. In this way, as they get older, children will begin to associate（联系） physical activity with higher learning," says Margaret.
Older people can beef up（加强） their brains as well. Columbia University studied a group of seniors ranging in age from（从...排列到） seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for infants（婴儿）, exercise for older people should involve some complexity. Learning some new skills or motions, such as with yoga or tai-chi, helps to open up memory paths in the brain that may not have been used for a long time.
For most people, any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.

TOEFL seats to increase by 80%
Eighty percent more Chinese students can take the Test of English as Foreign Language (TOEFL) through the Internet at the end of this year, the US Educational Testing Service (ETS) has said.
Net-based test seats will increase from 1,950 in June to 3,550 at the end of the year, an ETS press release said on Tuesday.
The ETS and China's National Education Examinations Authority worked jointly on their network to meet the increased demand for TOEFL in China.
Advanced technological solutions will be implemented by the ETS to monitor the TOEFL registration website to ensure an open and fair test registration process, according to the ETS.
More than 6,000 colleges and universities in 110 countries accept TOEFL scores. The number of students who want to take the test on the mainland has grown steadily in recent years, with the average staying above 70,000 a year.
"The ETS is committed to ensuring that everyone in China who wishes to take the test gets the chance to do so," ETS's global division senior vice-president Paul Ramsey said.
Some Chinese students see the announcement as an encouragement.
"It used to be very hard to get a chance to sit for the test, and I had to ask my friends to help take online registration on other computers," said Chen Lu, a second-year postgraduate student of Renmin University of China who took the test a few months ago to apply for doctoral studies in the US.
But some say the increase is still not big enough. "More and more students are preparing for TOEFL to get a chance to study abroad or to prove their ability. So I still see a gap between supply and demand," said Wu Qi, a final year undergraduate in Peking University.
