Today is Saturday. Ben, Kitty and Mum are at home. Ben and Kitty want to go out and play. But Mum doesn’t agree with them because it’s a rainy day. So they have to(不得不)stay at home and watch TV in the living-room. The weatherman on TV tells them that tomorrow will be a fine day. So they are very happy. Kitty plans to ride to the zoo with Alice and Ben wants to go and play football with his friends. There is no sugar and salt in the kitchen. So Mum needs to go to the supermarket tomorrow. All of them will be busy tomorrow.
