THREE RHYMING RIDDLES

1)

A word of six letters - a noxious drink,

Of whose effects you shudder to think.

Change my second letter - and then,

You convert me to a dreadful den.

And it's here where the one

Who gave you that drink,

Awaits a fate of which he shudders to think.

2)

My step is slow, the snow's my breath,

I give the ground a grinding death;

My own marching makes an end to me,

Slain by sun or drowned by sea.

3)

I'm food upon your plate,

When you eat in morning light;

I'm a drink inside your glass,

After dinner-time at night.
