In northern Scotland there is a long, deep lake called Loch Ness. More than 200 meters deep, it is the largest lake in the UK. People say a big monster（怪兽）lives in its dark, cold waters. It weighs more than 1,000 kilos and is at least ten meters long. Some people say it has a heard like a horse. Others say it looks like a snake. Many people travel to Loch Ness to look for this strange monster, but only a few people have seen it. At least, they say they have seen it.
The Loch Ness Monster is a famous legend（传说）. The first story about a monster in Loch Ness was told over 500 years ago, but the legend of the monster spread widely only in the twenties century. In 1933, a husband and wife reported that they saw a big monster in Loch Ness. Several people have taken photos, but at least one of them was a hoax（骗局）. During the 1960s, a team was formed to look for the monster. They took many photos and made movies, but they were never able to find a monster.
There is no real fact that a monster lives in Loch Ness, but there is also no fact that one doesn't live. One thing is true about Loch Ness: there are a lot of tourists there.
