五、典型例題解析
1.How often do you exercise? 你（你們）多久鍛煉一次身體？
How often + 助動(dòng)詞do(does或did) + 主語(yǔ) + do sth.? 疑問(wèn)詞how often是問(wèn)頻率(多久一次),（在這里助動(dòng)詞do(does或did) 是起幫助構(gòu)成疑問(wèn)的作用）與一般現(xiàn)在時(shí)或一般過(guò)去時(shí)連用，回答一般是用表示頻率的副詞，如：once, twice, three times…, sometimes, often, quite, often, never, every day, once a week , twice a month , three times a month , three or four times a month 等。
翻譯：
你們多久到工廠去一次？每星期兩次。 ?
他多久去購(gòu)一次物？”“一個(gè)月一次。 ?
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。”
第一個(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。
翻譯：
周末你通常做什么？我通常看電影。 ？
周末她通常做什么？她通�？催h(yuǎn)足。 ？
3. “What’s your favorite program?” “It’s Animal World.” “你最喜歡什么節(jié)目？”
4. As for homework , most students do homework every day .
as for...意思是 ，常用于句首作狀語(yǔ)，其后跟名詞、代詞或動(dòng)詞的-ing形式（即動(dòng)名詞）。如： As for him，I never want to see him here.
翻譯：至于我自己，我現(xiàn)在不想去。
