How much2. will EzhouHuanggang Bridge be finished(被完成)（2002黃岡市） In a few months. A. How soon B. How long C. How often D. How far考題解析： How long意為“多長(zhǎng)時(shí)間”，多用于對(duì)（for）時(shí)間段的提問

7、；how soon意為“多久以后”，多用于對(duì)in時(shí)間段的提問（以現(xiàn)在的時(shí)間為起點(diǎn)）；how often意為“每隔多久”，多用于對(duì)頻率的提問；根據(jù)各題答語(yǔ)，題1對(duì)時(shí)間段提問，選B；題2對(duì)in短語(yǔ)的提問，選A。“頻率副詞”一族說起“頻率副詞”，你可能不太了解。談起often，always，usually，sometimes，你一定會(huì)脫口而出，它們是一般現(xiàn)在時(shí)的“標(biāo)志詞”。它們是表示頻率的副詞。這些詞表示經(jīng)常性動(dòng)作或情況，不是某一具體動(dòng)作，常用于一般現(xiàn)在時(shí)。 這些頻率副詞在句子中的位置比較靈活，可以用于句首、句中和句末。在句中的位置一般在系動(dòng)詞be，情態(tài)動(dòng)詞（can，may，must等）或助動(dòng)詞（d

8、o，does等）之后，行為動(dòng)詞之前。這些頻率副詞在表示動(dòng)作發(fā)生的頻率時(shí)，程度上有所不同，可這樣表示： alwaysusuallyoftensometimes 1. always意為“總是，一直”。這是頻率最大的詞，表示動(dòng)作重復(fù)，狀態(tài)繼續(xù)，中間沒有間斷。如： Mary is always late for school. 瑪麗總是上學(xué)遲到。 2. usually意為“通?！保硎玖?xí)慣動(dòng)作，頻率僅次于always，相當(dāng)于most often。表示除個(gè)別情況外，基本上沒有變化。如： He usually gets up at 6 oclock. 他通常6點(diǎn)鐘起床。 3. often意為“時(shí)常，經(jīng)?！?/p>

9、，表示動(dòng)作重復(fù)，中間有間斷，表示發(fā)生的頻率比usually要小，但比sometimes要大。如： I often go to school by bike，but sometimes I go to school by bus. 我經(jīng)常騎自行車上學(xué)，但有時(shí)乘公共汽車去。 4. sometimes意為“有時(shí)”，表示發(fā)生的頻率最小。sometimes一詞在書寫時(shí)要十分小心，若分開寫成 some times就成了“好幾次，數(shù)次”。如： He has lunch in the factory sometimes. 他有時(shí)在工廠吃午飯。 I read this story some times. 這個(gè)故

He gets home from work at five thirty.2) We need outdoor exercise every day. So after the third class, everybody should go to exercise on the playground

13、. Its good for our health. 建議: 讓學(xué)生做一個(gè)pre-task, 在Book One、Book Two中找一找已學(xué)過的名詞動(dòng)詞兼類詞。 2頻度副詞表示的次數(shù)多少要求學(xué)生有大概的概念。 3英語(yǔ)中表示次數(shù)的多少應(yīng)該用： Once a week（每周一次），twice a week（每周兩次），three times a week（每周三次）。三次以上一般都用times表示。 “a week”短語(yǔ)還可用 a month，a year， every week， every year來代替。 4Its good for my health. But Im pretty hea

14、lthy. 句子中的health是名詞, healthy是形容詞。英語(yǔ)中有的名詞加詞尾可以變成形容詞。讓學(xué)生舉出更多的單詞。A TV programA: Do you often watch TV?B: Yes, I do. I watch TV everyday. It is my way to relax.C: No, I dont.

19、 This is because acid formation occurs within 30 minutes of consumption of food. However, this may be difficult most of the time because hardly any of us carry our toothbrush around.

22、nds. I used to play tennis a lot and go for long walks. In those days I didnt earn very much. I had a job in an office.

23、 longer, too. I bought a car and drove to work every day. And I began to take people out to lunch. “expense account” lunches. And I began to put on weight, too. I stopped playing tennis and going for walks at the weekend because I just didnt have any time for things like that any more. Theres a lot of stress in a job like mine. Perhaps thats why I started drinking more than I used to. For example, I used to have only half a glass of whisky when I got home, then I started filling the glass to the top. Then I had another glass, and then another.
