Nessie
Have you ever heard of the Loch Ness Monster? Many people believe that there is a huge animal (living/lived) in Loch Ness in Scotland.
The animal is about 50 metres long (including/included) its tail. Nobody knows anything about its (eating/eaten) habits. There are some photos of the animal (taking/taken) by different people (visiting/visited) the lake, but nobody can prove that they are real.
This animal (giving/given) the nickname Nessie has been one of the greatest tourists attractions to the area for years. Expeditions (sent/ sending) to Scotland tried very hard to find and catch Nessie. And so did individuals (looking/looked) for the animal. But there has been no result yet.
Nessie is still a great mystery. Very few things (knowing/known) about Nessie are: is has a long and thin neck like a giraffe’s, its head is quite small and looks like a horse’s, its colour is dark yellow and its habitat is the deepest and the coldest part of the lake.
