【题目】Are you preparing for a big test? If so, you may want to go to 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 (血管), including those in the brain, stronger and more fully developed. Dr. Cameron is sure that this allows people who exercise to think better. As she says, “While we already know that exercise is good for the heart, exercise can actually 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 show greater brain development than babies who are less physically active. Even a little movement can show big results. Margaret Barnes, a scientist, also believes in the importance of exercise. She thinks that many learning disabilities that children have in primary school or high school can result from a lack of movement as babies. Babies need movement that encourages and excites their five senses. They need to set up a connection between motion and memory. In this way, as they get older, children will begin to connect physical activity with higher learning,” says Margaret.

Older people can develop their brains as well. Cornell University studied a group of seniors who have 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 babies, exercise for older people should not be too simple. Learning some new skills or actions, such as with yoga or tat- 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 aim 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.

A. How exercise makes people strong.

D. How the brain can change one’s memory.

2According to the passage, what is the connection between exercise and brain development?

4Why is yoga suggested for seniors?

A. It does good to the joints of old people.

Do’s and Don’ts of Donating

Giving up your unused or unwanted stuff is a great way to make space in your home for the items that you do enjoy on a regular basis. Not sure where to start? Here are some do’s and don’ts of donating your belongings.

Do Prepare Your Clothes

You’ve thoroughly cleaned out your closet and drawers, and have a mountain of clothing waiting to be donated. 1 Make sure all buttons are accounted for, and that you can’t see any dirty marks, or damage.

2

The number one rule of donating your stuff is to make sure that it’s in good, usable condition. Don’t pass along old clothes or furniture, chipped dishes, books that are missing pages, or toys with lost pieces. Nobody wants to accept your damaged belongings. Find a local company that will recycle these items instead.

Don’t even think of donating these items

With a little common sense it’s easy to figure out items that are ideal for donations.3As a gentle reminder, it’s never a good idea to donate car parts, dangerous waste, construction materials and weapons.

Don’t donate large appliances

Major appliances such as stoves, fridges, freezers, washers and dryers typically reside on the ‘do not donate’ list due to health and safety reasons. All items accepted for donation must be thoroughly clean and in good working order. With secondhand appliances, it can be difficult to guarantee that they fit the bill.4

Don’t donate recalled items

Every so often a product recall hits the news headlines. Highchairs, toys, holiday lights for Christmas trees—the list of recalled items due to safety concerns is endless. 5 A dangerous product should be thrown away, and not passed on to an unsuspecting person. Think of the well-being of others before dropping off something that’s viewed as a hidden danger in your own home.

A. They’re all acceptable items for donation, too.

B. Instead of donating an unwanted large appliance, call your local trash collection company and arrange for their safe disposal.

C. But unfortunately some people will throw away the contents of their home without a second thought.

D. Before you bag up these pieces, inspect each one to ensure that they’re in good condition and ready to be owned by someone else.

E. Don’t donate damaged items.

F. Clothes aren’t the only household items that can be donated.

G. Never donate recalled items!
