(3) The Grey man lives on mountains in Scotland.

(4) It has a small head and a long tail and some people believe it is a dinosaur.

Step 2. Leading-in

Purpose: To let Ss have a discussion about the Monster of Lake Tianchi.

1. Group work

Show four pictures and ask Ss to say something about the Lake Tianchi and the monster.

2. Group work

Let Ss reported their discussions to the class and collect them. Then give a simple introduction to lead in the reading.

For your reference:

Lake Tianchi is located in the north-eastern Jilin province near the border of North Korea, in China. The lake is 1,243 feet deep and has had some volcanic activity in the last 300 years. Tianchi is honoured as the deepest mountain lake and the largest crater lake in China.

There have been more than 30 reported sightings by tourists from home and abroad over the past 20 years. They said that they saw the great monster in the lake. There are quite a few pictures and videos of this creature, but none is clear enough to give a good appearance of it. Some persons made the picture with computer images of it based on interviews. Someone drew a picture to show its shape, but it remains unconfirmed.
