      Lots of people like diving into water, because they can explore the underwater world. But there is

another kind of diving.  Some people dive into the sky! This is really a very exciting sport. A skydiver

goes high up in the air on a plane. Then he jumps off the plane and floats(飘)in the air with the help of 

a parachute(降落伞)．A parachute is like a huge umbrella.It is put on the back of the skydiver. When

the skydiver reaches a certain height, he will pull a string(细绳)and the parachute will open up in seconds

and carry him gently(轻轻地)down to the ground.  Skydivers like doing a lot of fascinate tricks in the

air.  After jumping off the plane one after another, they will try to stay in the air and hold each other's

hands. |They can form different shapes. Is it safe to do skydiving? Yes, as long as we receive right training. But sometimes, accidents do happen. In Canada, two skydivers were killed in 1991 when they jumped

off  the plane.  Because their parachutes got tied up with each other, the parachutes couldn't open up and

both crashed down and died.
