  A You know eating fruit and vegetables does good. But do you know it can also make you look good? People who increased their intake over just six weeks developed a healthy glow and appeared more attractive,researchers found. Scientists at St Andrews University found eating them slightly increased yellow and red pigments in the volunteers' skin. They monitored the food in?take of 35 people and took pictures of their faces,arms and hands using a sen?sitive camera at the start,and after three and six weeks. Increasing their in?take of greens by 2. 9 portions a day was found to make the person look more healthy and an extra 3. 3 portions could enhance their attractiveness,when their photographs were rated by others.

  Fruit and vegetables are rich in carotenoids (类胡萝卜素) ，which are known to protect against cell damage from pollution and UV rays,and can also prevent agerelated diseases including heart disease and cancer. But while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange,it was not known a small increase was perceptible (可察觉的) to others―and was seen as appealing.

  A camera measured changes to the skin's redness,yellowness and lightness,and found it significantly changed in people who naturally increased their intake. These changes were not evident in three weeks. Using light sensors,the researchers found these red and yellow hues were linked with the levels of ca?rotenoids in their skin. There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene (番红素) 一which gives tomatoes and red peppers their red colour―and betacarotene found in carrots as well as broccoli,squash,and spinach. Skin colour is also affected by chemicals called polyphenols (多元酚) ，found in apples,blueberries and cherries,which cause blood to rush to the skin surface.

  Busy as I am every day,I always open my com?puter and check my email. Most of the time I am sim?ply doing finger exercises,another form of piano prac?tice without beautiful tones. Sometimes,however,I ,receive a gift,reminding me of the gifts in my life. The following passage is one of those gifts.

  Peter Jones is a 92-year-old,short,calm and proud man. Every morning he is fully dressed by eight o'clock,with his hair fashionably combed and face per?fectly shaved even though he is unable to see anything. He would move to a nursing home today. His wife of 70 years old has recently passed away,making the move necessary.

  After hours of waiting patiently in the entrance hall of the nursing home,he smiled sweetly when told his room was ready. As he moved his walking stick skilfully to the elevator,the nurse provided a visual de?scription of his tiny room. "I love it," he stated with enthusiasm. "Mr Jones,you haven't been to the room," said the nurse.

  "That doesn't have anything to do with it”， he re?plied. "Happiness is something you decide on ahead of time. Whether I like my room or not doesn't depend on how the furniture is arranged but how I arrange my mind. I have already decided to love it. It's a decision I make every morning when I wake up. I have a choice ： I can spend the day in bed complaining of the difficulty I have with the parts of my body that no longer work,or get out of bed and be thankful for the ones that do."
