Twice a week.你們多久到工廠去一次？每星期兩次。 Eg2) How often does he go shopping? He goes shopping once a month. 2.“What do you usually do on weekends?” “ I usually play soccer.”“周末你通常做什么？”“我通常踢足球?！苯馕觯旱谝粋€(gè)do為助動(dòng)詞, 在這起幫助構(gòu)成疑問(wèn)的作用；而第二個(gè)do則是實(shí)義動(dòng)詞。Eg1) What do you usually do on weekends? I often go to the movies.Eg2) What does she usually do on weekends? She sometimes go hiking.5課堂練習(xí):(1).單選1）_do you do your homework? -Every day. A. When B. How often C. How many times D.
