她问我们是否愿意来帮她的忙。

    UN Chinese Language Day {#blank#}1{#/blank#} (celebrate) yearly on April 20. This year, Doreen Hynd was among those invitees, who are either experts on the Chinese culture {#blank#}2{#/blank#} have a special skill related to it.

    Hynd astonished all those present while performing Tai Chi, {#blank#}3{#/blank#} Chinese martial (武术的) art form, at an event held by the UN Tai Chi Club. The audience could hardly believe she was a 93-year-old grandma. It was definitely amazing that she could bend her body and raise her leg so {#blank#}4{#/blank#} (easy) and keep herself still standing on one leg.

    Hynd owes (归功于) all this to her continuous practice of Tai Chi.

    Born in Australia in 1925, Hynd began Tai Chi training in her 50s and then moved to the US, {#blank#}5{#/blank#} she later became an instructor herself.

    When {#blank#}6{#/blank#} (ask) about the greatest benefit she gained from Tai Chi, Hynd said, “balance.” Hynd has been teaching people of all ages and different {#blank#}7{#/blank#} (culture) backgrounds how to practice Tai Chi. They have benefited greatly from their association with the Chinese culture. They've developed a balanced state of mind and improved their health after {#blank#}8{#/blank#}（month）of practice. Tai Chi allows these people {#blank#}9{#/blank#}（understand）that, from the perspective（视角）of yin and yang, all things are closely connected with each other. This might be where the attraction of Tai Chi {#blank#}10{#/blank#}（lie）. Hynd enjoys sharing this great gift from China with her students.

    How would you feel if you woke up and found your entire computers—including your photos, your recent documents—no longer{#blank#}1{#/blank#}(access)? What if you found out that they had been wiped from your computer, {#blank#}2{#/blank#}(leave) you with nothing but heartache?

    Guess what? It happens to people every single day. Every day, people across the country head into their local Apple store in{#blank#}3{#/blank#} (tear), broken computer in hand, praying as they wait in line that an expensive repair might, just might, recover the priceless, irreplaceable files. A few get lucky. {#blank#}4{#/blank#}for the rest, there's nothing anyone can do{#blank#}5{#/blank#} (help).

    Hasn't it happened to you? If your computer remains unprotected, it will, and it's only {#blank#}6{#/blank#}matter of time. But thanks {#blank#}7{#/blank#}recent breakthroughs in computer backup (备份) technology, you now have a number of options to prepare, and if you' re smart, when your computer{#blank#}8{#/blank#} (crash), you shouldn't have any trouble{#blank#}9{#/blank#} (get) 100% of your files back that same day. I'm not talking about an external hard drive. I'm talking about an online backup solution that runs{#blank#}10{#/blank#} (quiet) in the background on your computer. If you have one installed (安装)，when your computer crashes, you'll be just one click away from bringing your files back to life.

    Our cat was ready to give birth to her kittens. My son was curious and excited to see the birth of these new babies. The event took place yesterday. The cat {#blank#}1{#/blank#}(give) birth to one kitten by the time he arrived home from school. He was so amazed at {#blank#}2{#/blank#} he saw. When the second was on its way, the mother cat began to yell very loudly. I saw tears in my son's eyes because he learned about the pain of giving birth.

It is widely accepted that optimistic attitudes promote health as well as happiness. The secret of a long life is {#blank#}1{#/blank#} (universe) desired and has long been sought. Today we can reveal it: always look on the bright side. A huge research project {#blank#}2{#/blank#} (lead) by scientists at the Boston University School of Medicine concludes that optimists live {#blank#}3{#/blank#} (long).

Lewina Lee, lead author of the study, said, "A lot of evidence {#blank#}4{#/blank#} (suggest) that exceptional longevity(长寿) is widely accompanied by a longer span of good health and living {#blank#}5{#/blank#} disability. Therefore our findings raise an exciting possibility {#blank#}6{#/blank#} we may be able to promote health and happiness by {#blank#}7{#/blank#} (develop) positive attitudes such as optimism."

However, the study doesn't suggest that we should aim for great pleasure. Sadness is {#blank#}8{#/blank#} important part of the human condition. Any normal person sometimes experience disappointment, ambitions and the {#blank#}9{#/blank#} (lose) of loved ones. But for many people, these matters of human existence {#blank#}10{#/blank#} (transform) into an abnormal state of despair. There is a vital place in public health for providing mental treatment in helping to correct these cognitive errors. It is not weakness to be defeated by setbacks. It is merely a mistake.
