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 (腦力上地) 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 (縱橫填字游戲) 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 (復(fù)雜度); otherwise, it will become repetitive (重復(fù)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 (認(rèn)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.
小題1: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.
D．How to make your brain healthy and work actively.
小題2:Which word can replace the word "boost" in the third paragraph?
A．Change.B．Promote. C．Decrease.D．Lose.
小題3: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
D．these puzzles can work on different areas of the brain
小題4:Which group of people have a slower rate of cognitive decrease?
A．Those who don’t often do crossword puzzles.
B．Those who don’t often count to 99 in threes.
C．Those who do their work very easily.
D．Those who can speak more than one language.

小題1:D
小題2:B
小題3:B
小題4:D

The skin which covers the tips of the fingers and thumbs is crossed by numerous ridges (隆起) arranged in different patterns. These patterns are permanent from birth and remain exactly the same throughout a person's life, even when the skin becomes wrinkled and cracked as a result of old age. Such patterns are never passed on from parents to children, and no one in the world has the same patterns as anyone else. Even identical twins have different sets of fingerprints. As a result, fingerprints offer a most useful and foolproof way of identifying people. Any ridged part of the hand and the foot may be used as a means of identification, but finger impressions are usually preferred since they can be taken easily and quickly.
Fingerprints are classified in the ways: by general shapes and contours(輪廓), by the finger positions of the pattern-types, and by size (often measured by counting the ridges in the loops). Every set of fingerprints has different “ridge characteristics” (i. e. the print of each separate finger is different from that of all the other fingers), which belong to one of four basic groups: arches, loops, whorls and composites. All fingerprints can then be divided into 1, 024 groups. By using details in the patterns above, these 1, 024 groups can be further divided into thousands of smaller groups, thus making it possible to find a particular set of fingerprints in a few minutes.
小題1:According to this passage, the true statement about human fingerprints is that ____.
A．people's fingerprints sometimes can be passed on from parents to children
B．people’s fingerprints are unique but identical twins may have the same fingerprints
C．using fingerprints is the only way to identify people
D．people's fingerprints will not change in all their lives
小題2:We prefer to use fingerprints to identify people because ____.
A．we can never find the same set of fingerprints among human beings
B．finger impressions can be taken easily and quickly
C．fingerprints offer a most useful and foolproof way of identifying people
D．a(chǎn)ll of the above
小題3:The word “foolproof” (Line 7, Para. 1) most probably means ____.
A．that is permanent　B．that is acceptable
C．that can not go wrong　D．that is not foolish
小題4:About the classification of fingerprints, which is TRUE? ____.
A．Fingerprints can be classified in three ways
B．All fingerprints can be divided into 1, 024 groups and can not be divided further
C．It is not easy to find a particular set of fingerprints in a short time
D．People can not classify the fingerprints in an effective way

She had been shopping with her Mom in Wal-Mart．She must have been 6 years old, this beautiful brown haired, freckle-faced image of innocence．Outside, it was pouring so heavily．
We all stood there just inside the door of the Wal-Mart．We waited, some patiently, others annoyed because nature messed up their hurried day．I got lost in the sound and sight of the heavens washing away the dirt and dust of the world．
Her voice was so sweet as it broke the hypnotic trance （昏昏欲睡） we were all caught in．"Mom, let's run through the rain," she said．
"No, honey．We'll wait until it slows down a bit," Mom replied．
This young child waited about another minute and repeated: "Mom, let's run through the rain．"
" We'll get wet totally if we do," Mom said．
"No, we won't, Mom．That's not what you said this morning," the young girl said as she tore at her Mom's arm．
"This morning? When did I say we could run through the rain and not get wet?"
"Don't you remember? When you were talking to Daddy about his cancer, you said, If God can get us through this, he can get us through anything!"
The entire crowd stopped dead silent．I dare say you couldn't hear anything but the rain．We all stood silently. No one came or left in. the next few minutes,Mom paused and thought for a moment about what she would say．
Now some would laugh it off and scold her for being silly．Some might even ignore what was said. But this was a moment of affirmation in a young child's lifetime when innocent trust can be developed so that it will bloom into faith．"Honey, you are absolutely right．Let's run through the rain．If get wet, well maybe we just need washing," Mom said．Then off they ran.
We all stood watching, smiling and laughing as they rushed past the cars and they held their shopping bags over their heads just in case．They got soaked．But they were followed by a few who screamed and laughed like children all the way to their cars．And yes, I did．I ran．I got wet．I needed washing．
You may lose your material possessions, your money and even your health, but no one can ever take away your precious memories．So don't forget to make time and take the opportunities to make memories．

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels(分貝) measured in water are different from those measured on land. A noise of 120 decibels on land causes pain to human ears. In water, a decible level of 195 would have the same effect.
Some scientists have suggested setting a noise limit of 120 decibles in oceans. They have observed that noises above that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises could seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing, which seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected(感染的).
Many researches whose work depends on ocean sounds disagree with a limit of 120 decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how many and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they previously believed. They want to prevent noises from harming creatures in the ocean.
小題1:The second paragraph mainly tells us that the noises on land and in water       .
A．a(chǎn)re both from human activities.
B．both do harm to sea animals
C．a(chǎn)re measured differently
D．have the same effect on humans
小題2:As to(依據(jù)) the effects of noises on whales, which of the following statements is TRUE according to the passage?
A．They are deaf to noises.
B．Noises at a certain level may hurt them.
C．They are easily confused by noises.
D．Noises will limit their ability to reproduce.
小題3:Many researchers think that the noise limit of 120 decibels would        .
A．protect whales from noises
B．benefit them a lot in their research work
C．do good to their health
D．increase industrial output
小題4:What will scientists most probably do in the future?
A．Count the number of sea animals.
B．Stop their research on the ocean.
C．Study the effect of different noises.
D．Protect sea creatures from harmful noises.

Wendy Gallegos writes “concer” on the board. One of her students raises her hand.
“Ms. Gallegos, you should have written ‘conocer’ instead,” she said, referring to the Spanish verb for “to know.”
Gallegos looks at the board, smiles and quickly erases her mistake.
“You see, I have taught you so well, you pick up on my mistakes,” she said with a laugh.
To Gallegos, the scene in her classroom is typical（特有的）of the children she teaches. Gallegos teaches high school Spanish. She became part of their lives and families for three years. She is willing to help her children succeed. After a couple of years, Gallegos’ class becomes like home. Gallegos’ Spanish class is taught mostly in English in sixth grade. By the time the students are eighth-graders, they are speaking fewer words of English and more of Spanish during the 50-minute classes.
“My goal is to get my kids to say something in Spanish every day,” she said, “I want them to be able to talk to me. That’s why I help them, I praise them, I recognize them when they do good work. And we have fun. The day I stop having fun is the day I am going to consider a different job.’’
If a student needs help, Gallegos offers the student a “l(fā)ifesaver,” which is help from a classmate. The lifesaver gets a piece of candy as a reward. As the students said: “Gallegos’ class is anything but boring.” It is because of Gallegos’ efforts and determination that she is the teacher who they think is most deserving of one of Collier County’s Golden Apple Awards.

A group of graduates, well established in their careers, were talking at a reunion and decided to visit their old university professor, now retired. During their visit, the conversation turned to complaints about stress in their work and lives.
Offering his guests hot chocolate, the professor went into the kitchen and returned with a large pot of hot chocolate and other things including cups-porcelain(瓷杯子), glass, crystal, some plain looking, some expensive, some elegant -- telling them to help themselves to the hot chocolate.
When they all had a cup of hot chocolate in hand, the professor said: "I notice that all the nice looking and expensive cups were taken, leaving behind the plain and cheap ones. While it is normal for you to want only the best for yourselves, that is the source of your problems and stress. The cup that you're drinking from adds nothing to the quality of the hot chocolate. In most cases it is just more expensive and in some cases even hides what we drink. What all of you really wanted was hot chocolate, not the cup; but you consciously went for the best cups... And then you began eyeing each others cups. Now consider this: Life is the hot chocolate; your job, money and position in society are the cups. They are just tools to hold and contain life. The cup you have does not define, nor change the quality of life you have. Sometimes, by concentrating only on the cup, we fail to enjoy the hot chocolate we have. The happiest people don't have the best of everything. They just make the best of everything that they have. Live simply. Love generously. Care deeply. Speak kindly. Thank the Lord for your blessings in 2011. And enjoy your hot chocolate in 2012!”
小題1: When did they decide to go to see their professor?
A．After the reunion.B．During the get-together.
C．Before they graduated.D．Just after the professor retired.
小題2:Why did the professor offer them different cups?
A．Because cups were not enough for everyone.
B．Because cups were beautiful.
C．Because the professor wanted to teach them something.
D．Because hot chocolate should be contained in different cups.
小題3:What caused the professor to say those words?
A．Their graduation.B．Their reunion.C．Their visit.D．Their complaints.
小題4:What does the word “cup” in this passage refer to?
A．LifeB．happy things in life
C．hot chocolateD．tools to hold and contain life
小題5:What is the purpose of the professor’s words?
A．To tell them life is not easy, so try their best to be happy.
B．To educate them that the happiest people don't have the best of everything.
C．To wish them to be grateful to their life and make the best of everything that they have.
D．To use different cups to tell them they should try different things in life.

The weather predictions for Asia in 2050 read like a story from a doomsday movie．
Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring．In the decades to come, Asia—home to more than half the world's 63 billion people—will change from one climate extreme to another, with tired farmers battling droughts, floods, disease, food shortages and rising sea levels．
"It's not a pretty picture," said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam．Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come．
Already, changes are being felt in Asia but worse is likely to come．Sawyer and top climate bodies say, and could lead to mass migration and widespread human disasters．According to predictions, icebergs will melt faster, some Pacific and Indian Ocean islands will have to evacuate or build sea defenses, storms will become stronger and insects and water-borne diseases will move into new areas as the world warms．
All this comes on top of rising populations and demand for food, water and other resources．Experts say environmental worsening such as deforestation and pollution will likely enlarge the results of climate change．
In what could be a sign of the future, Japan was hit by a record of 10 typhoons and tropical storms this year, while two - thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill．
The year before, a winter cold strike and a summer heat wave killed more than 2,000 people in India．
小題1:This passage is mainly about ____ ．
A．present situation and predictions of environmental problems in Asia.
B．the weather predictions for Asia in the future and the reasons
C．how to improve our environment
D．reasons why the world will no longer be suitable for us to live in
小題2:In the future the Asian farmers will have to face the following except ____ ．
A．food shortagesB．droughts C．warsD．floods
小題3:The underlined word "doomsday" in the first paragraph may mean____ ．

A．Asian climate will change greatly．
