Article: The tourism business in Hong Kong has been through some very hard times. Ten years ago, with all the economic problems in Asia, far fewer tourists were visiting Hong Kong. However, the SAR was still one of the most popular destinations in Asia, and a favored location for international meetings and exhibitions. The year 1997 was the best year for tourism in the 1990s. However in 1998, the figure was down by 8% from 10.4 million tourist arrivals recorded in the previous year. Tourism was still big business, though. The mainland was Hong Kong's largest source of visitors, making up over a quarter of all arrivals. Travelers from Taiwan Province, South and Southeast Asia and Japan made up the most of other visitors. Tourism remained a major source of foreign exchange, although tourists spending dropped. Tourists often made short visits, staying an average of three to four days. Most tourists came to Hong Kong for business or leisure , or a mixture of both. Shopping was still the favorite thing of tourist activity and spending. The average visitor spent about HK$ 3,000 - not including accommodation and food. Hong Kong Tourist Association officials developed various plans to develop interest in Hong Kong as a tourist destination, and they hoped these policies would work.

Article: Giant pandas are now extremely rare. Their number is less than 1,000 in the wild. The hunting of pandas has been banned for many years, so this is not the problem. Destruction of its habitat, when areas are cleared for growing crops, is one of the main reasons for panda's decline . Another reason is that the bamboo on which they mainly feed, is dying back. The pandas find it difficult to move to new feeding areas. As the bamboo disappears, the pandas simply starve to death. Bamboo is a poor source of food, and pandas have to eat up 45kg of it every day, a process that takes them up to 16 hours. The process goes on day and night, with the pandas in a constant cycle of eating for eight hours and sleeping for four. They can eat other foods, but will rather starve than change their diet when bamboo is scarce. Giant pandas are very good climbers, and use this skill to escape from the enemy. The giant panda lives alone for most of its life, only coming together with another of its species for long enough to mate. A newborn panda baby is born hairless and blind, is about 15cm long and weighs only 100g. The baby will stay with its mother for about 18 months, until it is able to set up its own territory Chinese and American scientists are studying giant pandas and their habits in order to put in place a major conservation programme. Zoos around the world are taking part in panda breeding programmes. There is still hope that with human's help, the giant panda can survive in the wild.
Answer: Nearly 2 tons
How much bamboo does a panda eat every year?

Article: I had recently arrived in London and I wanted to see some of the famous places. Should I go to the seaside? Or maybe one of the famous parks? I walked along the street, past a kindergarten playground, and suddenly saw an underground railway station. I was surprised because it was not on my map. I went to buy a ticket. The ticket-seller looked very old. He gave me a ticket, said "Remember it's a return", laughed and walked away without taking my money. Was it special for tourists? A train arrived. I could not see any other passengers. I got on and the doors closed. I suddenly felt I should not have got onto the train. It started to go faster and faster, shooting along the tracks. As it entered the tunnel, everything became as dark as midnight and I do not remember the next few minutes. The train came to a station and I got out. I could see light shining in the distance so I walked towards _ and came to a door. Beyond it there was a busy street. There were lots of English people walking about, and I could see some of the famous buildings of London, but there was something wrong. The people's clothes were strange. There were no cars, no motorbikes--but there were horses everywhere. Was someone making a film? "Excuse me," I said to a man. "Would you mind telling me where I am and what is happening?" "What do you mean? Who are you? Where do you come from? Are you from China? This is London and everyone's going to work. Can't you see that?" he asked. "Thank you, sir. I'm sorry, but could I look at your newspaper?" I asked. "You can have it," he said as he walked off. I looked at it; I saw "New Bicycle Law" and above that "July 5, 1880". Maybe I should have walked around, but I ran back to the door. I waited a long time. I was very afraid. A train came. I got on. It took me back to the first station. As I left, a woman asked, "What were you doing in that abandoned station?" I had no answer, but I still had the newspaper in my hand.
Answer: Because he couldn't find the station on his map.
