It's very easy
Piece of cake
It's impossible
When pigs fly
Raining a lot
It's raining cats and dogs
A person who pretends to be good but isn't
A wolf in sheep's clothing
Eating a lot of food
To eat like a horse
Don't hurry!
Hold your horses
You're daydreaming
Head in the clouds
Good luck
Cross your fingers
I'm very nervous
Butterflies in the stomach
Pretending to be sad
Crocodile tears
I've had enough
It's the last straw
Always following the rules
Goody two shoes
