Happiness means different things to different people. For Mary, who has {#blank#}1{#/blank#} severe sleeping problem, happiness is as simple as having a good night's sleep.

    Bed was once a place {#blank#}2{#/blank#} Mary went to rest after a long, hard day. {#blank#}3{#/blank#}, she has not had a full night's sleep in almost six months. Her doctor said that{#blank#}4{#/blank#}(count) sheep might help her fall asleep. She tried this, but soon got tired of it after it failed to work. She finds the nights without sleep almost {#blank#}5{#/blank#}(bear) . She is always sleepy and lacks energy during the day.

    Mary is not alone. Studies show that more than one in three people worldwide struggle with getting enough sleep. It often takes on different {#blank#}6{#/blank#}(form) : some people can get to sleep, but wake up much too early; some get a full night's sleep, but are {#blank#}7{#/blank#}(disappoint)  to find that they still feel tired when they wake up; others, like Mary, find {#blank#}8{#/blank#} difficult to fall asleep in the first place.

    Specialists say that people should not worry too much about this problem. In most cases, a lack of sleep {#blank#}9{#/blank#}(cause) by anxiety and pressure. It is important to keep yourself {#blank#}10{#/blank#} good spirits and to be positive. 

    Are you facing a situation that looks impossible to fix?

    In 1969, the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It{#blank#}1{#/blank#}(be) unimaginable that it could ever be cleaned up.The river was so polluted that it{#blank#}2{#/blank#}(actual) caught fire and burned. Now,ears later,this river is one of{#blank#}3{#/blank#}most outstanding（杰出的）examples of environmental cleanup.

    But the river wasn't changed in a few days{#blank#}4{#/blank#}even a few months. It took years of work {#blank#}5{#/blank#}(reduce) the industrial pollution and clean the water. Finally,that hard work paid off and now the water in the river is{#blank#}6{#/blank#}(clean) than ever.

    Maybe you are facing an impossible situation. Maybe you leave a habit{#blank#}7{#/blank#}is driving your family crazy. Possibly you drink too much or don't know how to control your credit card use.When you face such an impossible situation, don't you want a quick fix and something to change immediately?

    While there are{#blank#}8{#/blank#}(amaze) stories of instant transformation, for most of us the{#blank#}9{#/blank#}(change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be {#blank#}10{#/blank#}(patience).

    When you are thirsty, you can drink some green tea. It tastes good and it's very healthy. The Chinese {#blank#}1{#/blank#} （know）about the benefits of green tea since ancient times, and they use {#blank#}2{#/blank#} to treat everything from headaches to depression. They have {#blank#}3{#/blank#}（actual）been using green tea as a medicine for over 4,000 years.

    Nowadays, there is scientific evidence of the health benefits of green tea. According to one study {#blank#}4{#/blank#} （publish）in a cancer research journal, drinking green tea {#blank#}5{#/blank#}（reduce）the risk of some types of cancer {#blank#}6{#/blank#} nearly sixty percent. USA researchers have also found that green tea may prevent the{#blank#}7{#/blank#}（grow）of cancer cells. There is also new evidence {#blank#}8{#/blank#}green tea can help to destroy bacteria in our bodies. It is especially effective at getting rid of the bacteria on your {#blank#}9{#/blank#}（tooth）and keep them healthy!

    According to the Chinese proverb, “It is {#blank#}10{#/blank#}（good）to go without food for three days than without tea for one.” So, in brief, you should definitely try a cup of green tea. It seems that it can only do you good.

    The day before he heads to a war, an undefeated {#blank#}1{#/blank#} (command) named Qi has a dream in which he loses a battle and dies. When he wakes up, Qi gets ready to go and fight. While gaining successive victories, Qi decides to celebrate, although there is a final battle {#blank#}2{#/blank#} (wait) for him. When he gets {#blank#}3{#/blank#} (drink) and falls asleep in his tent, Qi's army {#blank#}4{#/blank#} (attack) by the enemy and he gets killed just as his dream predicted. This is the story that has inspired the latest Kunqu Opera production.

    As one of the oldest of the traditional Chinese opera {#blank#}5{#/blank#} (form), Kunqu Opera, which is about 600 years old, {#blank#}6{#/blank#} (combine) singing, dancing and lyrical recitation. Performed in the Suzhou dialect (方言).UNESCO listed Kunqu Opera as an intangible heritage(非物质文化遗产)of humanity in 2001.

    Earlier this year, a plan of combining Kunqu Opera and traditional Chinese idioms was developed, {#blank#}7{#/blank#} would allow young Chinese directors and Kunqu Opera performers {#blank#}8{#/blank#} (work) together. The young artists are working on developing original plays based on traditional Chinese idioms to keep {#blank#}9{#/blank#} tradition alive while making it popular again{#blank#}10{#/blank#} new ideas.

    Yesterday, another student and I, representing our university's student {#blank#}1{#/blank#}(associate), went to the Capital International Airport to meet this year's international students {#blank#}2{#/blank#} were coming to study at Beijing University. After half an hour of waiting for their flight to arrive, I saw several young people enter the {#blank#}3{#/blank#}(wait) area looking around curiously. I stood for a minute {#blank#}4{#/blank#}(watch) them and then went to greet them.

    The first person {#blank#}5{#/blank#}(arrive) was Tony Garcia from Colombia, closely {#blank#}6{#/blank#}(follow) by Julia Smith from Britain. After I met them and then introduced them to each other, I was very surprised. Tony approached Julia, touched her shoulder and kissed her {#blank#}7{#/blank#} the cheek! She stepped back appearing surprised and put up her hands, as if in defence. I guessed that there was {#blank#}8{#/blank#}(probable) a major misunderstanding. Then Akira Nagata from Japan came in smiling, together with George Cook from Canada. As they {#blank#}9{#/blank#}(introduce), George reached his hand out to the Japanese student. Just at that moment, however, Akira bowed so his nose touched George's moving hand. They both apologized – another {#blank#}10{#/blank#}(culture) mistake!
