許藩芳

The writer thinks that people's fear of snakes 18- irrational.

Snakes found in the sea are a menace to human beings because in water a swimmer or a fisherman can be taken by surprise.

It is because on a surface free from obstacles only a few species are capable of catching human beings. Through their bodies snakes can get the warning when human beings are approaching. "They can keep the rodent population in check, thus helping the farmers to a great extent,"

It is because the forward

movement itself is rather

slow.

A dense jungle or undergrowth is often the home of snakes. The vast majority of snakes are not poisonous.

10. It is because the man can kill

the snake before the fatal. moment comes to him,
