If you want to 小题1:_ your child"s results at school, you could do a lot worse than ensuring that they do plenty of exercise．Scientists have already shown that physical activity can make you cleverer．A team in America has used scans to show that an important part of the brain _小题2:_ grows in children who are fit．These youngsters tend to be more intelligent and have better _小题3:_ than those who are inactive．
Scientists also found that one of the most important parts of their brains was 12 per cent larger than those of unfit youngsters．They believe that _小题4:_ children to take exercise from a very young age could help them do better at school later．Researchers from the University of Illinois, in the U．S．, studied the brains of 49 children aged nine and ten using a magnetic resonance _小题5:_ scan, a technique which provides very detailed pictures of organs and tissues in the body．
They also tested the _小题6:_ levels of the children by making them run on a treadmill．The scientists found that the hippocampus（海马体）, a part of the brain _小题7:_ for memory and learning, was around 12 per cent larger in the fitter youngsters．
Professor Art Kramer, who led the study published in the journal Brain Research, said the findings had important _小题8:_ for encouraging individuals to take part in sport from a young age．"We knew that experience and environmental factors and socioeconomic status all _小题9:_ brain development," he said．"If you get some lousy（坏的） genes from your parents, you can"t really fix that, and it"s not easy to do something about your economic status．But here"s something that we can do something about． |
Directions: Read the following passage and choose the most suitable heading from A—F for each paragraph. There is one extra heading which you do not need．
A．The results explained why time passes quickly when we are dealing with more tasks
B．Time flies when you are having fun and drags when you are bored．
C．Volunteers were told to finish three different tasks in the study．
D．There are areas of the brain having the function of estimating time．
E．Concentrating on time passing is probably a more accurate perception of reality
F．Focusing on" the duration or the color the of image makes trips speed．
小题1:
Scans have shown that patterns of activity in the brain change depending on how we focus on a task． Concentrating on time passing, as we do when bored, will trigger brain activity which will make it seem as though the clock is ticking more slowly．
小题2:
In the study, 12 volunteers watched an image while researchers monitored their brain activity using MRI scans．Volunteers were given a variety of tasks．In one they were told to concentrate simply on the duration of an image, in another they were asked to focus on the color, and in a third they were asked to concentrate on both duration and color．
小题3:
The results showed that a network of brain regions was activated when more subjects were paid attention to duration．It is thought that if the brain is busy focusing on many aspects of a task, then it has to spread its resources thinly, and pays less heed（注意） to time passing．Therefore, time passes without us really noticing it, and seems to go quickly．
小题4:
However, if the brain is not stimulated in this way, it concentrates its full energies on monitoring the passing of time．This may make time seem to drag, but in fact the researchers found that the more volunteers concentrated on the duration of the images, the more accurate were their estimates of its duration．
小题5:
Lead researcher Dr Jennifer Coull said many of the areas of the brain involved in estimating time were the same that played a key role in controlling movement, and preparing for action．She said this overlap suggests that the brain may make sense of time as intervals between movements, in much the same way as a musician marks time with his foot, or an athlete anticipates the sound of a starter"s pistol（手枪）． |
Directions: Read the passage carefully and answer the questions or complete the statements in no more than 12 words．
The iPad is a tablet computer designed and developed by Apple．It is particularly marketed as a platform for audio and visual media such as books, periodicals, movies, music, and games, as well as web content．At about 700 grams （25 ounces）, its size and weight are between those of most contemporary smart phones and laptop computers．Apple released the iPad in April 2010, and sold 3 million of the devices in 80 days．
The iPad runs the same operating system as the earlier iPod Touch and iPhone．It can run its own applications as well as ones developed for the iPhone．Without modification, it will only run programs approved by Apple and distributed via its online store．
Like iPhone and iPod Touch, the iPad is controlled by a multi-touch display ?a break from most previous tablet computers, which used a pressure-triggered stylus（尖笔）．The iPad uses a Wi-Fi data connection to browse the Internet, load and stream media, and install software．Some models also have a 3G wireless data connection, The device is managed and synced（同步） by iTunes on a personal computer via USB cable．
Media reaction to the device has generally been neutral or positive, with more positive reaction after the device was launched．
（Note: Answer the questions or complete the statements in NO MORE THAN 12 WORDS．）
1．The Marketing Strategy of iPad is to make it ____ for audio and visual media．
2．The programs approved by Apple can only be bought from ____．
3．How do people control some previous tablet computers?
4．What"s the media reaction to the device prior to its launch? |
