​"DIVING"

​ENGLISH SPARK READING - WEEK 7

Directions: Read the short story and answer the following questions.​

​Diving

​Humans do not have the capacity to breathe underwater unaided by external devices. A diver who wants to stay underwater for more than a few minutes must breathe air on a special mixture of gases. He can wear diving suits and have air pumped to him from above or he can carry tanks of air on his back and breathe through a hose and a mouthpiece.

​

​Early divers discovered that it is not enough to supply air to breathe comfortably underwater. The diver’s body is under great pressure in deep water because water weighs 800 times as much as air. Tons of water push against the diver deep in the sea.

​Diving

​When this happens, his blood takes in some of the gases he breathes. When the diver rises to the surface, the water pressure becomes less. If he rises too quickly, the gases in his blood form bubbles that make breathing difficult. He suffers from bends, causing him to double up in pain.
