Pilates(普拉提), yoga and running, whether in the gym or at home, get all the attention when it comes to popular ways to keep fit.    1    (与它们相比，散步不是这么有吸引力，但它却有很多益处。)

Certified fitness professional Jolynn Jaekel explains, “What I love about walking is that anyone can do it at any age and any fitness level. Besides, it is good for your heart, your head and your wallet.     2    (很明显，散步是让人惊叹的运动，不是吗？)”

Scientists at the Lawrence Berkeley National Laboratory in California found that quick walking reduced the risk of heart disease more effectively than running.     3     (正是因为这个原因，一些有心脏病的人喜欢散步胜于跑步。) Scientists observed participants aged between 18 and 80 over a six-year period and found that walking reduced the risk of heart disease by 9.3%, while running reduced it by 4.5%. And there is better news: 30 minutes of quick walking over five days could help people sleep easily, according to research by Oregon State University.    4    (散步帮助青少年更好地睡眠，使得他们积极参加学校活动并专注于学校生活。)

    5    (你越早开始，你将会越早注意到散步对你的大脑和身体有巨大影响。) So, go out for your 30-minute walk in a nearby park or green space.

I want to thank you for your last letter.     1     I felt very happy when I saw it. I’m so glad I have persuaded you to apologize to Rachel. Isn’t it great to have good friends? Speaking of friends,     2       I’ve met some nice people here in London and I think we might become close friends. I decided to write rather than e-mail you about my new friends because it’s always nice to receive a letter from someone special.

I met Monica when I joined the school badminton team.     3     我们彼此相处得非常好 and soon a great friendship developed.     4       She invited me to go to her house and watch DVDs. We have been friends ever since. My other friend is Jane. She always lets me borrow her Maths notes. She is hardworking and seems to try her best all the time. How are you doing at school?     5     我迫不及待要再见到你。

Yours,

Sally

In the West, if you are going to visit someone’s home, it is polite to take a present with you. Flowers, wine and sweets are all good choices. However, if you want to impress the host or hostess,     1     why not bring with you something handmade?

It is always wise to bring books about China to your foreign friends     2     目的是为了让他们更多地了解中国. If you think books are too ordinary, you can bring some traditional handicrafts such as fans.     3     In the past, fans were used not just to cool oneself. Sometimes fans were decorated with paintings or poems. When you give your friends the present, you can tell them a little about Chinese history. For the hostess, you can give her silk or a present with beautiful Chinese decorations, such as a handmade purse or a Chinese comb. I’m sure she will like it.

You can also give your foreign friends something to eat or drink.     4     你可以做一些中国菜and take them to your friends’ house. You can also bring Chinese tea. Tea is a national drink in China. It is an important part of Chinese culture.

    5     If you need to bring a present to children, toy pandas are a good choice. The giant panda is China’s national treasure. It is popular around the world.
