A rainforest is an area {#blank#}1{#/blank#} (cover) by tall trees with the total high rainfall spreading quite equally through the year. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate.{#blank#}2{#/blank#}the forest cover, these areas would reflect more heat into the atmosphere,{#blank#}3{#/blank#} (warm) the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.

    In the past hundred years, humans {#blank#}4{#/blank#} (begin) destroying rainforests in search of three major resources: land for crops, wood for paper and other products, land for raising farm {#blank#}5{#/blank#} (animal). This action affects the environment as a whole. For example, a lot of carbon dioxide in the air comes from burning the rainforests. People{#blank#}6{#/blank#} (obvious) have a need for the resources we gain from cutting trees{#blank#}7{#/blank#} we will suffer much more than we will benefit.

    Rainforests are often called the world's drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their{#blank#}8{#/blank#} (medicine) value. It is extremely likely {#blank#}9{#/blank#} our best chance to cure diseases{#blank#}10{#/blank#} (lie) somewhere in the world's shrinking rainforests.

    The Great Wall was listed as a World Heritage by UNESCO in 1987. Just like a dragon, it winds up and down across deserts, grasslands and mountains,{#blank#}1{#/blank#}( run) approximately 21,196 kilometers from east to west.

    The{#blank#}2{#/blank#}( construct) of the Great Wall was not that easy, {#blank#}3{#/blank#}drew heavily on the local resources for building materials. The walls were{#blank#}4{#/blank#}( original) built in the Spring & Autumn Period and the Warring States Period. Emperor Qin Shi Huang succeeded in his effort to have them joined together. Since then, the Great Wall{#blank#}5{#/blank#}( serve) as a monument of the Chinese nation throughout history.

    With {#blank#}6{#/blank#}history of about 2,700 years, some parts of the Great Wall are now {#blank#}7{#/blank#}ruins or have disappeared. However, the Great Wall of China is still one of the most appealing{#blank#}8{#/blank#}(attraction) all around the world owing to its historical significance. The best-known part of the Great Wall of China, Badaling, {#blank#}9{#/blank#}(locate) 43 miles northwest of Beijing, attracts thousands of national and foreign tourists every day.

    Today, the Great Wall{#blank#}10{#/blank#}(recognize) as one of the most important impressive architectural achievements in history.

    Sometimes our emotions can seem to defeat us. When this happens, {#blank#}1{#/blank#}is possible to give people the wrong {#blank#}2{#/blank#}(impress) or do something we regret. Learning to express your emotions effectively will allow you to communicate clearly and carefully, without hurting those around you or{#blank#}3{#/blank#}(make) the situation worse. So it's important to learn to express emotions.

    Firstly, you need to learn how to express your angry feelings. Anger can cause you to say things you regret, so sometimes you should control your angry feelings. If you're afraid of saying something that hurts someone, then try to think{#blank#}4{#/blank#}(care) before you speak. Also, you can write down your angry thoughts as if you were shouting it out to the world. This allows you{#blank#}5{#/blank#}(express) your anger.

    Secondly, it's necessary to learn to express sadness. Sadness is particularly hard to deal{#blank#}6{#/blank#}, especially when people can see you are sad. But you needn't hide it. Instead, try talking about {#blank#}7{#/blank#}is making you sad. It doesn't matter if you cry, as it has proved that crying can reduce stress. What's more, if you feel your secrets are safe in your dairy, then write down what{#blank#}8{#/blank#}(upset) you.

    Learning to express worry is also important. If you're worried about a friend or a loved one, talk to them about your worry. This could give you some peace of mind. Also, you can choose an activity {#blank#}9{#/blank#}you are interested in and spend some time doing it. The less you think about the problem, the {#blank#}10{#/blank#}you will worry.

    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.

    A few years ago, after a long morning of sightseeing in New York, my children and I took a rest on a park bench in Central Park.

    "Look!" my son said, {#blank#}1{#/blank#} (point) to a nearby rubbish bin. That's when we saw our first raccoon (浣熊). Quite at home in the big city, he paid us no attention, concentrating only on finding a {#blank#}2{#/blank#} (taste) lunch. He sorted through a few options before coming out with a wrapped sandwich {#blank#}3{#/blank#} (hold) between his paws.

    {#blank#}4{#/blank#} (surprise), rather than run away, he jumped down and walked casually to a spot on the path, not a metre from {#blank#}5{#/blank#} we sat. The children were spellbound, the raccoon providing better {#blank#}6{#/blank#} (entertain) than any museum. He glanced at us, perhaps checking to see {#blank#}7{#/blank#} we were about to steal his lunch.

    {#blank#}8{#/blank#} his fingers, he peeled back the layers of plastic wrap until the half-eaten sandwich {#blank#}9{#/blank#} (uncover).

    Then he surprised us all. Instead of starting his food, he {#blank#}10{#/blank#} (turn) to a nearby pool of water and dipped his paws in. With a casual air, he rubbed his paws together underwater for a moment, brushed his fur, then started gracefully picking at his meal.
