Your smartphone can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little equipment of yours----- it might also spread disease.

“People are just likely to get sick from their phones as from handles of the bathroom, ” Jeffrey Cain, the president of the American Academy of Family Physicians , told The Wall Street Journal.

This may be hard to believe, but scientists reached this conclusion after they tested eight cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms (大肠菌), a kind of bacteria found in human waste , with about 2700 to 4200 units of the bacteria on each phone. The bacteria can cause flu, pinkeye and other diseases . That is right --- your phone is covered in our human waste.

Although computers, keys and pens carry germs (细菌) , our phones get far dirtier. They touch a lot of things, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn’t played Angry Birds or Fruit Ninja while sitting on the toilet?

“Some things that we think are personal are actually more public than we imagine,” Cain said.  What is even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don’t think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease (油脂) , an environment that germs really like.

So how do you keep your phone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone’s surface: wash your hands regularly.

Dreams can be familiar and strange, fantastical or boring, but some dreams might be connected to the mental processes that help us learn. No one knows for certain why people dream, but some dreams might be connected to the mental processes that help us learn. In a recent study, scientists found a connection between nap-time dreams and better memory in people who were learning a new skill.

In the study, 99 college students between the ages of 18 and 30 each spent an hour on a computer, trying to get through a virtual maze(迷宫). The maze was difficult, and the study participants had to start in a different place each time they tried — making it even more difficult. They were also told to find a particular picture of a tree and remember where it was.

For the first 90 minutes of a five-hour break, half of the participants stayed awake and half were told to take a short nap. Participants who stayed awake were asked to describe their thoughts. Participants who took a nap were asked about their dream after sleep — and they were awakened within a minute of sleep to describe their dreams.

Stickgold, a neuroscientist (神经科学家), to know what people were dreaming about when their eyes weren’t moving, during sleep.

Four of the 50 people who slept said their dreams were connected to the maze. Some dreamed about the music that had been playing when they were working; others said they dreamed about seeing people in the maze. When these four people tried the computer maze again, they were able to find the tree faster than before their naps.

Stickgold suggests the dream itself doesn’t help a person learn — it’s the other way around. He suspects that the dream was caused by the brain processes associated with learning.

All four of the people who dreamed about the task had done poorly the first time, which makes Stickgold wonder if the dreams show up when a person finds a new task particularly difficult. People who had other dreams, or people who didn’t take a nap, didn’t show the same improvement.

1.Before having a short nap, participants of the experiment were asked to ________.

A. stay in different place in the maze

B. design a virtual maze which is difficult to get through

C. experience the experiment and try to remember something

D. get through a virtual maze on a computer from the same place

2.After doing what they were asked on computers, participants ________.

A. were divided into two groups to do different things at break

B. were so tired as to fall asleep

C. felt bored with the experiment and they were sleepy

D. were asked to remember their experiment separately

3.What can we learn from the passage?

A. Participants who took a nap were required to express their thought.

B. Some dreams may encourage people to invent something new.

C. Participants who dreamed about films could finish the task more easily.

D. Participants whose dreams had something to do with the maze could find the tree faster.

4.According to Stickgold, ________.

A. every person may dream about what they learned

B. people’s brain processes may still be connected with their learning in their dreams

C. once people’s eyes stop moving, they are sure to dream about something

D. no matter how fantastical or boring, dreams are connected with people’s life
