It was a short flight from Shanghai to Xi' an. Xi' an is one of the four great ancient capitals of Chinaover 3,100 years of history. Its ancient walls date from the Ming Dynasty and are the best  (preserve) in the world. There are bicycles for people to hire. It is (amaze) to ride along the walls to survey this fascinating city.

    The Tang Dynasty Music and Dance show is not to be missed, but my favorite is an art gallery, we can enjoy some beautiful artwork and learn how to write Chinese characters.

    Most tourists makeway to Xi' an to see the life-size terracotta warriors (兵马俑) and we were no  (difference). The collection, which shows the armies of the first Emperor of China, (remain) hidden until 1974 when they were discovered by a farmer sinking a well. Walking among the statues is forbidden unless you are a VIP — but there are plenty of souvenir(shop) in which tourists can buy the replicas(复制品)of them.

    All too soon it was time(leave). I really enjoyed my stay in Xi' an. It is indeed a place of interest worthsecond visit.

    To be a good journalist, there are many things to do. Maybe the following suggestions could strongly  your life as a journalist.

    Don't go out on a story immediately. Firstly, you should work as a(n), then you can cover a story by yourself.

    You needn't take a camera with you, because the  photographer with you takes photographs. Your colleagues are very  to assist you.

    You need to be curious about covering the story. Only if you have a good ＂nose＂ for a story can you  all the information you need.

    Listening is also important. You have to listen for  facts.  you have to prepare the next question depending on what the person says.

    Make use of the trick of the . Sometimes a recorder is used. It is also useful if a person wants to  you. You have the  to support your story.

    Many English language learners believe that the  (great) difficulty with listening comprehension (理解) is that the listener cannot control how quickly a speaker speaks. They feel that what the speaker says disappears  they can follow. This frequently means that students  are learning to listen cannot keep up. They are so busy working out the meaning one part of what they hear that they miss the next part. Or they (simple) ignore a whole section because they fail to catch it quickly enough. Another difficulty is that the listener is not always in a position to get the speaker to repeat what has been said. And, of course, repeats cannot (ask) for when listening to the radio or watching TV.

    Besides, (choose) of vocabulary is in the hands of the speaker, not the listener. Very often, for people listening to a foreign language, an unknown word can be like a suddenly  (drop) stone making them stop and think about the meaning of the word, (cause) them to miss the next part of the speech. In listening, it really is a case of “He who (stop) to work out the meaning is lost.”

    Five meteorologists (气象学家) who were trapped for two weeks after polar bears surrounded their weather station are now able to leave after the creatures were chased away. Their supervisor told NBC News early Wednesday.

    Russian officials had feared the siege could last for another month, the time it would take to reach the islands in the Kara Sea, high in the Arctic Circle. But on Tuesday night a research ship took a detour (绕道) to assist those weathermen, station supervisor Vasily Shevchenko told NBC News. The ship run by Russia's state-run oil firm Rosneft frightened away the bears using its helicopter, before resupplying the weather station with more food and puppies (幼犬) . The puppies are not yet big enough to deter the bears, but the station is planning to draft in a replacement adult guard dog as soon as possible.

    Some of the bears had taken to sleeping directly outside the windows of remote outpost. There was no risk of the researchers starving because they had a year's worth of food, but they were forced to take dangerous trips to a nearby building, holding a gun for protection, according to Shevchenko.

    Polar bears are an endangered species. In Russia, it's a crime to shoot them unless in self-defense. The bears usually leave the islands in the summer, but this time they were trapped by the melting ice, an apparent sign of climate change, according to Shevchenko. “They've stayed on the island because there is nowhere for them to go,” he said.

    The animals suffer from global warming because it shrinks the floating ice that forms their main hunting ground. According to the environmental group the World Wide Fund for Nature, known as the WWF, this has got some polar bears to go near human habitats in search of food.
