You will spend hours at the gym training your body, but do you ever think about training your brain? Here are four ways to keep your brain mentally (脑力上地) active and healthy.
Play games
Your brain is a muscle just like the ones in the rest of your body. If you don’t use it, you will lose it. For example, doing a crossword puzzle (纵横填字游戏) once a day is a good way to give the brain the exercise it needs. This kind of puzzle is good at training different areas of the brain. But remember that when doing this puzzle, you should gradually increase the complexity (复杂度); otherwise, it will become repetitive (重复乏味的) and stop being mentally challenging.
Talk aloud
Although it might sound strange to you, talking aloud is a great way to boost your memory. A good exercise to try is counting to 99 in threes as fast as you can.
Be a team leader
If you find you can do your work very easily, you should find a new task. It is important that your job should be mentally challenging. Complex jobs are often more challenging and make the brain work a little harder.
Learn a language
A study found that, compared with those who could speak only one language, the people who could speak two languages had a slower rate of cognitive (认知能力) decrease. Learning a new language is very challenging and it makes sure that different areas of the brain have their lights on.What is the main idea of this passage?
| A．Why you should train your brain. |
| B．How to be a good team leader. |
| C．Training the brain is more important than training the body. |

We should gradually increase the complexity when doing crossword puzzles because ______.
| A．if we don’t use our brain, we will lose it |
| B．we should make our brain face different challenges |
| C．our brain is a muscle like other parts in our bodies |

A primary school has banned Valentine’s Day cards because of concerns that young pupils spend too much time talking about boyfriends and girlfriends.
Ashcombe Primary School in WestonsuperMare，Somerset，has told parents that cards declaring love can be “confusing” for children under the age of 11，who are still emotionally and socially developing.
In his February newsletter(简讯)，Peter Turner，head teacher，warned that any cards found in school would be confiscated.
He wrote，“We do not wish to see any Valentine’s Day cards in school this year.Some children and parents encourage a lot of talks about boyfriends and girlfriends.”
“We believe that such ideas should wait until children are mature enough emotionally and socially to understand the commitment involved in having or being a boyfriend or girlfriend.”
Mr.Turner said any families wanting to support the Valentine’s Day concept should send cards in the post or deliver them to home addresses by hand.
His views were supported by Ruth Rice,46，who has twins Harriet and Olivia,9，at the school.
She said，“Children at that age shouldn’t really be thinking about Valentine’s Day，and they should be concentrating on their schoolwork.”
“They are at an age when they are easily influenced and most parents including myself are with Mr.Turner.”
She added，“The cards caused too much competition.If someone gets a card and another doesn’t then he or she will be disappointed.”
However，Rajeev Takyar,40，who sells newspapers and has two children Jai,11，and Aryan,5，at the school，said he was “genuinely outraged”．
He said，“There are schools that have banned conkers(康克戏) and snowballs，and now Valentine’s Day cards.”
“I think banning the cards stops children from having social skills.How are they going to learn about relationships otherwise？It’s ridiculous.”
Alec Suttenwood，founder of the AntiPolitical Correctness Group，said of the ban，“It’s totally ridiculous.Young children just send the cards to each other as friends and to their parents.It’s just a bit of harmless fun.There is no difference between this and Mother’s or Father’s Day.”Valentine’s Day cards may cause confusion among young children because ________.
| A．they are too young to understand what love is |
| B．teachers haven’t taught them how to make friends |
| C．children shouldn’t learn about social relationships |
| D．students talk too much about boyfriends and girlfriends |
The underlined word “confiscated” in Paragraph 3 can probably be replaced by “________”．
| A．collected | B．destroyed | C．taken away | D．burnt away |
Ruth Rice was in favor of Mr.Turner’s view in that ________.
| A．children like to compare Valentine’s Day cards |
| B．children should focus their mind on their lessons |
| C．sending holiday cards wastes both time and money |
| D．making friends has a negative influence on children |

On May 23,1989, Stefania Follini came out from a cave at Carlsbad, New Mexico. She hadn’t seen the sun for eighteen and a half weeks. Stefania was in a research program, and the scientists in the program were studying body rhythms (节奏)。In this experiment Stefania had spent 130 days in a cave, 30 feet in depth.
During her time in the cave, Stefania had been completely alone except for two white mice. Her living place had been very comfortable, but there had been nothing to fell her the time. She’d had no clock or watches, no television or radio. There had been no natural light and the temperature had always been kept at 21℃.
The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn't kept to a 24-hour day. She had stayed awake for 20-25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 17lbs in weight as a result! She had also become rather depressed (抑郁).
How had she spent her time in the cave? As part of the experiment she'd done some physical and mental tests. She'd recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she'd played cards, read books and listened to music. She'd also learned French from tapes.
The experiment showed that our body clocks are affected by light and temperature, For example, the pattern of day and night makes us wake up and go to sleep. However, People are affected in different ways. Some people wake up naturally at 5:00 am, but others don't start to wake up till 9:00 or 10;00 am. This affects the whole daily rhythm. As a result, the early risers are at their best in the late morning. The late risers, on the other hand, are tired during the day and only come to life in the afternoon or evening!

It was a cold winter day. A woman drove up to the Rainbow Bridge tollbooth (收费站). “I’m paying for myself, and for the six cars behind me,” she said with a smile, handing over seven tickets. One after another, the next six drivers arriving at the tollbooth were informed, “Some lady up ahead already paid your fare.”
It turned out that the woman, Natalie Smith, had read something on a friend’s refrigerator: “Practice random kindness and senseless acts of beauty.” The phrase impressed her so much that she copied it down.
Judy Foreman spotted the same phrase on a warehouse wall far away from home. When it stayed on her mind for days, she gave up and drove all the way back to copy it down. “I thought it was beautiful,” she said, explaining why she’d taken to writing it at the bottom of all her letters, “like a message from above.” Her husband, Frank, liked the phrase so much that he put it up on the classroom wall for his students, one of whom was the daughter of Alice Johnson, a local news reporter. Alice put it in the newspaper, admitting that though she liked it, she didn’t know where it came from or what it really meant.
Two days later, Alice got a call from Anne Herbert, a woman living in Marin. It was in a restaurant that Anne wrote the phrase down on a piece of paper, after turning it around in her mind for days.
“Here’s the idea,” Anne says. “Anything you think there should be more of, do it randomly.” Her fantasies include painting the classrooms of shabby schools, leaving hot meals on kitchen tables in the poor part of town, and giving money secretly to a proud old lady. Anne says, “Kindness can build on itself as much as violence can.”
The acts of random kindness spread. If you were one of those drivers who found your fare paid, who knows what you might have been inspired to do for someone else later. Like all great events, kindness begins slowly, with every single act. Let it be yours!Why did Natalie Smith pay for the six cars behind her?
| A．She knew the car drivers well. |
| B．She wanted to show kindness. |
| C．She hoped to please others. |

| C．decided to write it on a warehouse wall |
| D．wanted her husband to put it up in the classroom |

| A．Kindness and violence can change the world. |
| B．Kindness and violence can affect one’s behavior. |
| C．Kindness and violence can reproduce themselves. |

| D．People who receive kindness are likely to pay it back to the giver. |
