Mèo định bắt một chú chuột Nhắt và một chú chuột Cống. Chuột sợ Mèo nên tìm cách chạy xa khỏi Mèo. Chú chuột Nhắt luôn di chuyển sang trái 1 ô mỗi lần. Chú chuột Cống luôn di chuyển sang phải một ô mỗi lần. Mèo mỗi lần nhảy được 2 ô sang trái hoặc sang phải. Nếu Mèo quyết định bắt chuột Cống trước thì sau ít nhất bao nhiêu bước nhảy sẽ bắt được cả hai chú chuột? Biết ba con luôn di chuyển đồng thời.

I. Read the conversation and do the tasks below. Nam: Hello? Mr Long: Hello, Nam? This is Uncle Long. Is your dad there? I’d like to ask him out for a game of tennis. Nam: Well, I’m afraid he can’t go out with you now. He’s preparing dinner. Mr Long: Is he? Where’s your mum? Doesn’t she cook? Nam: Oh, yes. My mum usually does the cooking, but she’s working late today. Mr Long: How about your sister and you? Do you help with the housework? Nam: Yes, we do. In my family, everybody shares the household duties. Today my sister can’t help with the cooking. She’s studying for exams. Mr Long: I see. So how do you divide household chores in your family? Nam: Well, both my parents work, so we split the chores equally - my mother cooks and shops for groceries, my father cleans the house and does the heavy lifting, my sister does all the laundry, and I do the washing up and take out the rubbish. Mr Long: Really? It’s different in my family. My wife handles most of the chores around the house and I’m responsible for the household finances. She’s the homemaker and I’m the breadwinner. Anyway, I have to go now. Tell your dad I called. Bye. Nam: Oh yes, I will. Bye, Uncle Long 1. Which word from the conversation means “divide and share”? ____________. 2.
