听力原文： In public speaking, the watch word is preparation. Most of us tend to put things off, at least occasionally. It's so easy to put things off especially those things we do not look forward to doing. So if the speaking engagement is several weeks off, we may feel that we still have plenty of time. But as the day draws closer, we begin to panic. Don't let this happen to you. Start preparing as soon as you're given or accept the speaking assignment. You have much to do and to do it right will take time. How much better your speech will be and how much better you'll feel if you have taken the time to do it right! When you are prepared, you have gathered the needed data, determined what is appropriate to the listener's understanding and acceptance levels, organized the ideas so they flow logically, selected examples and other supports for your ideas and made them interesting to your listeners, developed a great opening that you know will capture the attention of even the daydreamers in your audience checked out the room where you'll be speaking and requested any feasible changes you wish in the set-up of the room If you are prepared, you are confident that you can best convey your message to your listeners. If you waited until a few days before your presentation to begin to prepare, or worse, yet, the day before, no doubt you'll be anxious and with good reason. And now there is not enough time to engage in more than a superficial attempt. Both you and the audience will feel uncomfortable, like retirement planning. It is never too early to start preparing for your presentation. So, start preparing right away.

When you are at school, have you ever been told to stop daydreaming and concentrate? __1__. However, understanding how to do it, and knowing what is distracting(使分心)you，can help.
Scientists have looked at what makes us distracted and found a number of ways to help us stay in the zone. __2__. Research by Science Focus magazine found silence or gentle background music is best for concentration. So studying in a quieter location helps us focus on the task at hand. It's also necessary to put your phone in another room or switch it off altogether.

Regular exercise can also help to improve your quality of sleep which is vital in helping your focus. __4__, preferably before you study, or between two study sessions.

Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitive areas such as attention and memory. This is true regardless of age.
People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.
Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. “The idea is not necessarily to learn to memorize enormous amounts of information,” says James Fozard, associate director of the National Institute on Again. “Most of us don't need that kindof skill. Such specific training is of less interest than being able to maintain mental alertness.” Fozard and others say they challenge their brains with different mental skill, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.
Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. “The point is, you need to do both,” Cohen says. “Intellectual activity actually influences brain-cell health and size.”
6. People who are cognitively healthy are those _______.
A、who can remember large amounts of information
B、who are highly intelligent
C、whose minds are alert and receptive
D、who are good at recognizing different sounds
7. According to Fozards argument people can make their brains work more efficiently by _______.
A、constantly doing memory work
B、taking part in various mental activities
C、going through specific training
D、making frequent adjustments
8. The findings of James and other scientists in their work _________.
A、remain a theory to further proved
B、have been challenged by many other experts
C、have been generally accepted
D、are practiced by the researchers themselves
9. Older people are generally advised to ___________.
A、keep fit by going in for physical activities
B、keep mentally active by challenges through specific training
C、maintain mental alertness through specific training
D、maintain a balance between individual and group activities
10. What is the passage mainly about？
A、How biochemical changes occur in the human brain.
B、Why people should keep active not only physically but also mentally.
C、How intellectual activities influence brain-cell health
D、Why people should receive special mental training as they age.
