Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球場) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

There are many environment-friendly sport. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”.

Ever walked to the shops only to find, once there, you’ve completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we’ve accepted that a forgetful brain is as much a part of aging as wrinkles and gray hair. But now a new book suggests that we’ve got it all wrong.

According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s — much later than previously thought.

Furthermore, rather than losing many brain cells as we age, we keep them, and even produce new ones well into middle age. For years it’s been assumed that brain, much like the body, declines with age. But the longest, largest study into what happens to people as they age suggests otherwise.

This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that on average, participants performed better on cognitive (認知的) tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving. Where they performed less well was number ability and perceptual speed — how fast you can push a button when ordered. However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are now coming up with scientific proof that we do get wiser with age.

Neuroscientists are also finding that we are happier with aging. A recent US study found older people were much better at controlling and balancing their emotions. It is thought that when we’re younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we’ve learned our lessons and are aware that we have less time left in life: therefore, it becomes more important for us to be happy.

1.Barbara Strauch probably agrees that ______.

A. the young are better at handling important things

B. people’s brains work best between their 40s and 60s

C. aging leads to the decline of the function of the brain

D. wrinkles and gray hair are the only symbols of aging

2.The continuing research has found older people perform better on ______.

A. perceptual speed B. number ability

C. vocabulary tests D. body balance

3.People are happier with aging because ______.

A. they learn to value the time left

B. they know how to share feelings

C. they cannot focus on negative aspects

D. they do not realize the possible dangers

4.What is the main idea of the passage?

A. People get happier with age.

B. People get wiser with age.

C. People get more forgetful with age.

D. People get more self-aware with age.

My darling daughter,

Recently I saw a diary of years. It was written when you were nine. I read your goals in the diary, and one little goal was really surprising for me. It was “to make Mom happy”.

I was so moved, and I would have told you that you made me happy every day of my life. My first thoughts in the morning were of you. When I got home from work, I couldn’t wait to see you. I liked talking to you very much and I wanted to know what your day was like. You kept my spirit alive, my mind challenged and my body active. You were, and still are, the light of my life. Without you, my life would have been boring. You made me happy and you continue to do so.

You are a mother now, with a child of your own. I know you love her, so I think you should tell her how happy she makes you. Sometimes we forget to say the words that are in our hearts. These words can be very important to a child. They can change their world completely. They can create a beautiful world for them.

You are my joy in life, my little one. You always have been, and you always will be. Never forget that, and tell that to your child. Tell her that she is the most important thing in the world for you, because she makes things joyful in your life! I love you, my dearest daughter.
