学 习 过 程
一、预习与交流A、翻译下列句中的 ( http: / / www.21cnjy.com )汉语：1. （也许 ( http: / / www.21cnjy.com )）he is at home, but his father (也许) not at home.2. --- （多久一次）do you exercise --- Every day.3.

He never speaks Japanese. （3）对句中的频度副词提问，使用How often(多久)， 如：She hardly ever wat ( http: / / www.21cnjy.com )ches TV on weekends. How often does she watch TV 2. sometime 将来某时 ( http: / / www.21cnjy.com ) some time 一段时间 sometimes = at times 有时 some times 数次3. health (n) 健康 healthy (adj) 健康的 healthily (adv) 健康地4. exercise = take exercise = do sports=play sports 锻炼She exercises once a day.= She does exercise once a dayexercise作名词 表“运动，锻炼” 是不可数名词；表“体操，眼保健操”是可数名词。Doing eye exercises is good for your eyes. 做眼保健操对你的眼睛有好处。5. hard可充当形容词和副词两种角色 ( http: / / www.21cnjy.com )。用作形容词有“硬的”，“困难的、艰难的”的意思。其中用作“难的”讲时，在口语中与difficult通用。The problem is too hard, I can't work it out. 这个问题太难了，我算不出来。 hard也用副词，意为“努力地、刻苦地”，“猛烈地”，注意不要把hardly当作“努力地、刻苦地”来用。hard用作“猛烈地”讲时，同heavily相同。 He works hard only before exams. 他只在考试前努力学习。 It is raining hard outside. You can't go out. 外面正下着大雨。你不能出去。 hardly只用作副词，其词义不要与hard(adv.)相混淆。其意思是“几乎不”、表示否定概念.注意 hard与hardly用作副词时，词义可是有很大差别。 He works hard. 他努力工作。 He hardly works. 他几乎不工作。四、课堂练习.A、用所给单词适当形式填空1. He often (have) dinner at home.2. Daniel and Tommy (be) in Class One.3. We (not watch) TV on Monday.4. Nick _______(not go ( http: / / www.21cnjy.com )) to the zoo on Sunday.
