—Mum, let’s go shopping together.— Can’t you see I’m so busy, dear? I ______ tomorrow’s meeting.
-- How long has your son __________ the ipad2? -- Only about two weeks.
-- May I use your mobile phone, Meimei? --Sorry, I _________ it at home.
--Don’t _________ too late, or you will feel sleepy in class. --I won’t, Mum. Good night!
-- It’s too cold outside. Would you mind closing the window ? -- __________.
I prefer ________ at home rather than _________ out for a picnic on a rainy day.
