ДАЮ 80 БАЛОВ!!!!!! READ THE CONVERSATION BETWEEN AMY AND HER MUM. WRITE THE LIST OF FOOD AMY AND HER FATHER ARE GOING TO BUY IN THE SUPERMARKET ON THE PAPER BAG.

Mum: Hello?

Amy: Hi, Mum. It’s Amy. Dad and I are here at the

supermarket. We’ve got your list, and we’re doing

the shopping, but we’ve got some questions. Mum: No problem, Amy. What do you want to know?

Amy: We’ve got the crisps and biscuits for my school snacks, but Dad and I don’t know what type of oil to buy.

Mum: Get olive oil. I always cook with olive oil because it’s the healthiest type of oil.

Amy: Right, olive oil. Now, should we get orange juice or fizzy drinks?

Mum: Get both. We’ll have orange juice for breakfast and fizzy drinks with dinner tonight.

Amy: Speaking of dinner ... you’re making beef with baked beans, right?

Mum: Yes, that’s right. Beef with baked beans is your dad’s favourite meal. It will be ready in half an hour, so please hurry. And don’t forget the carrots. I want carrots for the salad. In fact, get about half a kilo of carrots.

Amy: Right, carrots and peppers are on the list and Dad’s getting them right now. What about dessert? What’s for dessert?

Mum: Would you like fruit salad or watermelon?

Amy: Watermelon is a great idea! Uh, Mum, I love watermelon but I don’t know how to choose a good

one.

Mum: Ask your dad to show you. He knows how to

choose a perfect watermelon.

Amy: Dad, can you help me choose a watermelon?

Mum, we’re getting the watermelon. We’ll just pay

and come right home.

Mum: Get some popcorn, too, so we can have popcorn

and watch a film on TV after dinner. Amy: OK. See you soon.

Mum: Bye!
