Running is the best way to get fit.
  There's no best method to get fit. You have to enjoy your exercise or you will find reasons to quit. Nobody can get fit or lose weight or build a muscle in an instant. Fitness requires time and patience, and you get rewards as you go along. If you are looking only at running or at instant success, you are looking for trouble!
  If you don't exercise an hour a day, six days a week, you do nothing.
  Don't believe in this all-or-nothing way. Even if you exercise as little as three times a week for half an hour you will benefit from it. However, if you want to get fit for sport, you may have to work out five to six days a week.
  Warming up before working out isn't necessary if you're careful.
  Warming up is a must before you exercise. Warming up and stretching not only help you avoid injuries but also prepare your heart and body to accept the shock of an increased workload.
  No pain, no gain.
  Pain means that the body is showing that there is something wrong. If you feel painful when exercising, either slow down or stop the exercise. To gain from exercise, you may have to make do with a bit of discomfort, but pain is different. If you continue exercising with pain you may damage a muscle or tendon forever.
  Taping （用绷带包扎） an injury prevents further damage.
  If you are injured and you tape it for support, chances are that you will aggravate the injury further. What's more, you may injure other joints because of the limited flexibility（灵活性） that the taped knee or ankle allows.

When Peng Liyuan stepped off the plane in Moscow, the whole world wanted to know who dressed the elegant first lady. The reporter released the secret--Ma Ke.
  Peng Liyuan has been wearing Ma Ke's designs for more than a decade, a fact that was only highlighted recently when she was on her first state visit, accompanying her husband President Xi Jinping. The elegant and attractive Peng, formerly a popular singer, has been compared with the US' first lady Michelle Obama and France's Carla Bruni- Sarkozy, since stepping off the airplane in Moscow on March 22． Suddenly, everyone was curious to know more about the first lady's wardrobe.
  Even so, Ma prefers a low-key approach." If you eat a tasty egg why would you want to see the hen？" she says of all the media attention.
  Ma's relationship with Peng began 10 years ago after a concert in Guangzhou when a reporter told Peng she knew the designer behind the label Exception de Mixmind. Peng asked for an introduction because she was a fan of Ma's designs and had been wearing them for years.
  The two naturally became friends. Ma says： "The painting reflects the painter, and clothes reflect both the designer and the wearer. Someone desires fame and wealth, or love and sympathy； what you have in your heart is reflected in the design. Those who don't share my philosophy won't buy my clothes. Peng is a caring person, devoted to charity and environmental protection, which is exactly what I'm doing now."
  However, regardless of the brand, Peng's support of Chinese labels has surprised millions of Chinese who favor foreign fashion brands.
  "Instead she presented a vision of Chinese fashion, desiring to bring Chinese designers to the world stage," says a western designer.
  The first lady's double-breasted coat and her black leather handbag aren't available at any of Exception's shops, though Exception's physical stores do have seen a rising number of visitors.



The passage mainly discusses ______ ．

A. the friendship between Peng Liyuan and her designer
B. the designer of the first lady Peng Liyuan's dress, Ma Ke
C. Peng Liyuan's clothes on her first state visit
D. the reactions to Peng Liyuan's first visit to Moscow

In the underlined sentence in Paragraph 3 Ma Ke mentioned "an egg and the hen" to show ______ ．

C. the outcome was more important than the process
D. her dissatisfaction with the media attention on her dress

C. Ma Ke offered to design the first lady's clothes through her friends.
D. Peng had liked Ma's designs long before she got to know her in the flesh.
