How do you remember the way to your house? Where do dreams come from? It is your brain(大脑) that does these things. A British scientist showed that “sleep can improve one’s memory.” It’s not a dream for students to study when they sleep. In fact, your brains is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(天才按钮)” in the human brain. It might make a person more talented.
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠) keeps our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
l Eat healthy food.
l Get a lot of playtime or exercise.
l Don’t drink or smoke.
l Use your brain a lot.

A reader wrote in to say that she was feeling lonely at break because her best friend
wasn’t around．Here’s our advice to her—and to all kids who feel lonely sometimes．
It’s hard when a best friend isn’t around—maybe because she moved to a different
school or a different class．You may feel lonely at break or lunchtime．You want to have new
friends．but how do you make them? Maybe it seems like everybody else already has their
friends．But remember, there’s always room for more friends． 。．
Start by looking around your classroom—think about which kids you’d like to play
with at break．Look for chances to say hi to them，smile，and be friendly．Offer to share
something or express your appreciation(欣赏)to them．Invite someone to play with you or
say “Do you want to sit here?” in the lunchroom．When you’re at break，walk over to kids
you want to play with．act friendly，and say “Hi，can l play, too?” or just join in．
If you have trouble doing this or if you’re feeling shy, ask your teacher to help you make
new friends．Teachers are usually pretty good at matching up friends．The best way to make
friends is to be a friend．Be kind，be friendly，share，say nice things，offer to help—and pretty soon，you’ll have one，or two，or even more new friends.
You might still miss that special best friend．But when you see each other, you can share
something you didn’t have before she left：You can introduce her to your new friends!
