题目内容

Work your brain!
Between 2 and 3 pounds of wonder，it controls everything we say，do or think，who we are and what we care about. The way we walk or laugh or figure out things. What we like and the talents we possess. How we see and talk and run and jump and process our food.
The brain uses 20 percent of our body's oxygen and 20 percent of its blood. Somewhere within its protein，fat, 100,000 miles of blood vessels and 100 billion nerve cells，it helps us remember where we put our gym shoes. Change our temperature so we don't die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orangeflavored drinks.
Its intricacies(复杂性)are stunning，far beyond anything most of us can imagine. To keep this work of art as polished(有光泽的) as possible we need to eat right，exercise and keep mentally stimulated(刺激)．
Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone(荷尔蒙)in our brain that improves memory. Mental stimulation keeps you sharp even as you age.
“It's very important that we tell people to be physically active and mentally active，” said neurologist Malcolm Stewart.
“People cannot stop aging，but you're able to reduce the damage；you're able to keep the function up.”
Following are Dr.Stewart's advice for improving brain health：

Nutrition	Avoid fast food. Follow the old adage(格言，谚语)：For breakfast，eat like a king；for lunch，like a queen；for supper，like a beggar.
Exercise	Do a combination of stretching aerobic and musclestrengthening every day.
Mental games	Try to have a sense of hope about the future. Do puzzles. Listen to music. Reach out to others to make their lives better.

It`s 2035. You have a job, a family and you`re about 40 years old! Welcome to your future life.

Getting ready for work, you pause in front of the mirror. “ Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronics (智能电子元件) are rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe you`re 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You`re not even middle-aged!

As you go into the kitchen and prepare to pour your breakfast cereal into a bowl , you hear, “To lose weight , you shouldn`t eat that.” from your shoes. They read the tiny electronic code (电子源码) on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible foods appears on the counter as the kitchen checks its food supplies.

“Ready for your trip to space?” you ask your son and daughter. In 2005 only specially trained astronauts went into space – and very few of them. Today anyone can go to space for day trips or longer vacations. Your best friend even works in space. Handing your children three strawberries each , you add, “The doctor said you need these for space travel.” Thanks to medical advances, vaccination shots(防疫针) are a thing of the past. Ordinary foods contain special vaccines. With the berries in their mouths, the kids head for the front door.

It`s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office. Autopilot.” you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video film rather than read it.

55. What changed the color of your shirt?

A. The mirror

B. The shirt itself

C. The counter

D. The medicine

56. How do the shoes know that you shouldn`t eat the breakfast cereal?

A. By pouring the breakfast into a bowl

B. By listening to the doctor`s advice

C. By testing the food supplies in the kitchen

D. By checking the nutrition details of the food

57. The strawberries the children eat serve as________.

A. breakfast B.lunch

C. vaccines D. nutrition

58. How is the text organised?

A. in order of time

B. in order of frequency

C. in order of preference

D. in order of importance

In the face of tragedy(悲剧), you must of course let yourself feel: Cry without holding back, tremble with fear, yell out in anger, accept and follow your feelings. This is part of the wise approach to tragedy: The Upward Path – the feeling of emotions(情感), the acceptance of them, and the coupling of the emotional mind with wisdom. Along this path, you’ll take the experience – no matter how sad or upsetting – as a learning event, just as all other points on your journey will prove to be. While tragic, you must recognize this is still a chance for all involved to grow. You should let both sadness and joy, fear and courage, dark and light fill your world, and learn to find your steady, calm center in the midst of the opposing forces. This is the Upward Path. Use the event as a chance to gain balance and discover wisdom – the wisdom of love and of letting go, of non-attachment and non-resistance, and using this experience to eventually help others in need of guidance.
Being able to relate to others who have also experienced tragedy and inspire in them hope – of recovery, and of moving forward – is perhaps the greatest gift you can receive from tragedy. Turn the negative into positive, the pain into connection. After you’ve taken appropriate time to be sad, to feel your own pain, you should make it your work, your goal, your purpose to connect with others who need help. Show them how you’ve experienced feelings, achieved balance, and gained wisdom that you would never have otherwise had the chance to learn.
Feel, but do not Feed on tragedy. Rather, let it inspire you to go beyond the person who you were before. With demise comes renewal, so let this loss be also your rebirth. No matter how hopeless it seems, no matter how difficult this becomes, you have the power to transform yourself into someone greater than you ever knew you could be.
【小题1】When following the Upward Path, the person facing tragedy should _______.

A．free his emotions

B．hold back all his feelings

C．fill his world with positive ideas

D．give in to tragedy and all opposing forces
