5、）But my mother wants me to drink it. “want sb. to do sth.” 想叫某人做谋事”The teacher wants us to clean the classroom right now.I want him to help me with my English.2) She says its good for my health. “Its good for” 那对有好处。Dont read in the sun.

How much2. will EzhouHuanggang Bridge be finished(被完成)（2002黄冈市） In a few months. A. How soon B. How long C. How often D. How far考题解析： How long意为“多长时间”，多用于对（for）时间段的提问

7、；how soon意为“多久以后”，多用于对in时间段的提问（以现在的时间为起点）；how often意为“每隔多久”，多用于对频率的提问；根据各题答语，题1对时间段提问，选B；题2对in短语的提问，选A。“频率副词”一族说起“频率副词”，你可能不太了解。谈起often，always，usually，sometimes，你一定会脱口而出，它们是一般现在时的“标志词”。它们是表示频率的副词。这些词表示经常性动作或情况，不是某一具体动作，常用于一般现在时。 这些频率副词在句子中的位置比较灵活，可以用于句首、句中和句末。在句中的位置一般在系动词be，情态动词（can，may，must等）或助动词（d

8、o，does等）之后，行为动词之前。这些频率副词在表示动作发生的频率时，程度上有所不同，可这样表示： alwaysusuallyoftensometimes 1. always意为“总是，一直”。这是频率最大的词，表示动作重复，状态继续，中间没有间断。如： Mary is always late for school. 玛丽总是上学迟到。 2. usually意为“通常”，表示习惯动作，频率仅次于always，相当于most often。表示除个别情况外，基本上没有变化。如： He usually gets up at 6 oclock. 他通常6点钟起床。 3. often意为“时常，经常”

9、，表示动作重复，中间有间断，表示发生的频率比usually要小，但比sometimes要大。如： I often go to school by bike，but sometimes I go to school by bus. 我经常骑自行车上学，但有时乘公共汽车去。 4. sometimes意为“有时”，表示发生的频率最小。sometimes一词在书写时要十分小心，若分开写成 some times就成了“好几次，数次”。如： He has lunch in the factory sometimes. 他有时在工厂吃午饭。 I read this story some times. 这个故

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. 建议: 让学生做一个pre-task, 在Book One、Book Two中找一找已学过的名词动词兼类词。 2频度副词表示的次数多少要求学生有大概的概念。 3英语中表示次数的多少应该用： Once a week（每周一次），twice a week（每周两次），three times a week（每周三次）。三次以上一般都用times表示。 “a week”短语还可用 a month，a year， every week， every year来代替。 4Its good for my health. But Im pretty hea

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.
