No one can believe that the Great Wall might disappear some day. Believe it or not, the Great Wall is being destroyed by people. Less than 20 percent of the Great Wall built in the Ming Dynasty is still perfect, but about 80 percent is in danger. The Great Wall can be called "great" mostly because of its amazing length. But we should realize that the length was made up of one brick at a time. If we do nothing to save the Great Wall, it will become a series of separate wasteland rather than a historic site.

    The Great Wall is actually a series of walls built and rebuilt by different dynasties over the past 2,000 years. It began in the rule of China's first emperor, Qin Shihuang of the Qin Dynasty, and lasted into the Ming Dynasty. The parts built before the Ming Dynasty have nearly disappeared. People are familiar with sections such as Badaling in Beijing and Jiayuguan in Gansu because they have been open to tourists for many years. But those sections far away from the public eyes have been almost forgotten.

    Few local people knew the 3­metre­high walls made of earth and stones beside them are part of the Great Wall. The lack of knowledge is considered as one of the main reasons.

    The bricks on the Great Wall were carried off by local countryside people to build their houses,  sheep corrals (畜栏) and pigsties (猪圈). Some were taken away to build roads. Bricks carved with people's names are put away as remembrance (纪念). Rubbish is spread over the  battlements (城垛). The bricks can be sold for 15 yuan per tractor load. Those who destroyed and are destroying the Great Wall know its name, but are not clear about its cultural meaning. It will take a long time to let them know this. The local farmers not only carried off the body of the Great Wall but dug out the entire base.

    It is necessary to preserve the Great Wall. The officials should be aware of the importance of the Great Wall. Young Chinese should know more about the nation's great civilization and learn to love it.

    Tahiti is one of the largest islands of French Polynesia. It is located in the southern Pacific Ocean. The capital of Tahiti is Papeete, which lies on the northwest coast. This island has mountains that are volcanic (火山产生的). The people of Tahiti came from Polynesia. The Spanish first discovered this island, but they didn't rule it. Tahiti is close to South America and Los Angeles is just seven and a half hours' journey away by air. The scenery is beautiful and tourists often spend their vacations there.

    The weather in Tahiti is warm and there are heavy rains in the mountainous areas. The weather doesn't change much, so it is generally sunny. The weather is important for the plants and animals on this Polynesian island. The green rain forest is home to a lot of plants and animals. Flowers are seen here and there.

    Tourism is an important industry in Tahiti. There are many archaeological (考古学的) wonders, which are worth seeing in Tahiti. There are also festivals and activities such as boat riding, shark feeding and whale watching which are interesting experiences for travelers.

    Tahiti is a dream destination for divers as the sea waters are warm all year round and are full of active sea life, Raiatea Mountain is where mummies(木乃伊) of former rulers of Tahiti are kept. The people here consider it a holy place.

    Travelers are welcomed and a travel agent can help plan a well­arranged trip to Tahiti.

    My wife Lynn was beginning her third day on an oxygen mask (氧气面罩). "She must1in the next twenty-four hours, or you will probably leave her here," the doctor said to me. Those2words had me near the breaking point. However, I didn't want to3.

    Suddenly, a(n)4 hit me. Then I5 the nurses' station. There I got a piece of6 I wrote, "Keep Hope Alive! Miracle (奇迹) in Progress!" Then I returned to Lynn's room and put it up on the7, hoping somehow that those words would bring a miracle.8, there was not any sign of9. In the afternoon, the shift changed and a10 who I had not seen before came in. She had a soft smile and a11 manner. "I'll be helping Lynn tonight," she said. She gently cleaned her face and body. After finishing her work, she was ready to12, but she stopped when she noticed the13on the wall. She said to me, "Don't14, sir! I believe she will be fine. You know, my name is Tammy Miracle." It was 15. What were the chances of a nurse named Tammy Miracle being sent to Lynn on a day when I had put up a sign16 a miracle?

    The next morning, Lynn was awake. I couldn't help 17. The other day, I was further18 to learn that Tammy Miracle had been called in from other department due to a shortage of ICU nurses. I am 19 that Tammy Miracle was sent to us. So if you20 hope, try to believe that an angel may be looking for you, too.
