Do you and your friends ever talk about your dreams with each other? If you do, you might have noticed something interesting – some of your friends seldom remember their dreams, but some can always describe their dreams so clearly that it seems like they're describing things that really happened to them. What makes those people different?

    The answer is simple. There are two different types of dreamers – low dream recallers（回忆者）and high dream recallers.

    Low dream recallers usually remember their dreams only twice a month. But high dream recallers are able to remember them about five mornings a week. And a new study suggests that activity in a certain part of the brain could have something to do with it, reported The Huffington Post.

    Perrine Ruby, a French researcher at the Lyon Neuroscience Research Center, studied 41 people (21 high dream recallers and 20 low dream recallers) and recorded their brain activity.

    She found that a part of the brain called the temporo-parietal junction (颞顶联合区) was more active in high dream recallers than in low dream recallers – both when they were sleeping and awake.

    This brain area collects and processes（编程）information from the outside world. This means that high dream recallers know more about what's happening around them. For example, when they are awake, they respond (对……有反应) more strongly to hearing their own names, and when they are sleeping, they are woken more easily by sounds and movements.

    By closely studying people's brain activities, Ruby found that high dream recallers have twice as much “wakefulness time” during sleep as low dream recallers do. And it is during these short times of wakefulness that the brain remembers dreams.

    “The sleeping brain is not able to remember new information,” Ruby told The Washington Post. “It needs to wake up to be able to do that.”

    This is not hard to understand. Just try to think of your own sleeping experiences. If you are worried during the night, you are more likely to remember your dreams, but if you sleep well, you will remember little in the morning, and this is because “you never get a chance to remember”, Robert Stickgold, a Harvard Medical School researcher, told The Washington Post.

    Nowadays, computers and Internets are playing an important part in our life. Some people even say they can't live without them. We usually need to set passwords (密码) when we use computers and Internet. But not all the passwords are safe. In order to keep our accounts (账户)and personal information safe, we must learn how to make safe passwords.

    How can you make your computer and Internet passwords safe? Experts have some advice for you. You'd better remember the advice and they are useful for you. Here are the suggestions.

    Firstly, make your password out of capital(大写) letters. If your password is made of capital letters, it will be difficult for others to get into your account. It only takes a hacker(黑客) 10 minutes to work out a six- letter password made of small letters. But the same password in capital letters takes 10 hours to work out.

    Secondly, add numbers or symbols to your passwords. It may be much safer. Sometimes such password is not easy to remember, but it is really safe.

    Thirdly, never use personal information for passwords and use different passwords for different accounts. Experts say that a user should change his or her passwords every 90 days. In this way, hacker won't guess your passwords.

   The cold wind blew strongly outside. Amaya was warm in her house, thinking about an article she'd read at school. The article was about kids who helped out their communities, and she thought it would be really cool to help her own town, Harvard.

   The only problem was that she wasn't sure how to help. In the article, the kids had grown food for people who needed food, but it was winter. She couldn't start a garden. Amaya was deep in thought when her mom said it was time to go shopping.

   As they drove along the road, Amaya saw a family walking on the sidewalk(人行道), wearing only light jackets. How could they must be! That gave her an idea! She could collect winter coats, hats and gloves for people who needed them.

   She shared her idea with her mom, who thought it was great. But how would they spread the idea to get plenty of winter clothing? Amaya decided to talk to her teacher, because then she could share her idea with her classmates at least.

   Ms. Monroe agreed when Amaya talked about her idea. They decided to call the project Hats in Harvard. Then they wrote a letter explaining the project. Ms. Monroe even said she could help Amaya talk to the headmaster aboutit, so they could get the whole school to join in it. They met with the headmaster during lunch time. He was excited about the idea, and said he would make sure copies(复印件) of the letter went home with all the students.

   They collected enough winter clothing in only one week. Then they left the clothes around two parks, so families who needed clothes could get them there. Three days later, Amaya and her mom went shopping again. She saw the same family that had given her the idea for Hats in Harvard. This time, though, the family looked nice and warm in some new coats, hats and gloves. Amaya felt warm in her heart, and was very glad she could help others.
