Unit2 How often do you exercise? 一．重点知识解读 1. I hardly ever watch TV.我几乎从不看电视。 （1）hardly只用作副词，意为“几乎不；几乎没有”，表示否定概念，相当于almost not。如： There is hardly any food left,is there?几乎没有食物剩下了，是吗？ （2）hardly ever意为“几乎从不”。如： ①Peter is hardly ever late.彼得几乎从不迟到。 ②She hardly ever eats anything for lunch.她午饭几乎不吃东西。 跟踪练习 I could_____________(hard) hear her because of the loud noise. 2. No,I never go shopping.不，我从不去购物。 （1）never是常用的表示频率的副词，意为“从不”。如： Tom is never late for school.汤姆上学从不迟到。 （2） go shopping意为“去购物”。“go+v.-ing”形式表示进行某项活动。 如：go swimming/shopping/skating/skiing/fishing/climbing/hiking（去游泳/购物/滑冰/滑雪/钓鱼/爬山/徒步旅行）。 跟踪练习 ①他永远不会伤害任何人。 _________________________________________________________________________ ②我妈妈经常在星期天早上去购物。 _________________________________________________________________________ 3. I go to the movies maybe once a month.我大概一个月去看一次电影。 maybe 意为“大概；或许；可能”，作副词，常位于句首或句中。如： Maybe they are going to the beach.或许他们将去海滩。 词汇辨析-辨析：maybe与may be maybe是副词，在句子中作状语。may be是由情态动词may与动词原形be构成，作句子的谓语，意为“可能是”，它们有时也可互换。如： Maybe they are in your schoolbag.=They may be in your schoolbag.或许它们在你的书包里。 跟踪练习 ①He may be in the office. =________________________________________________________________________ ②He may know where she comes from. =________________________________________________________________________ 4.She says it's good for my health.她说这（喝牛奶）对我的健康有好处。 be good for..意为“对……有好/益处”，其反义短语为be bad for...，意为“对……有害处”。如： Taking a walk after dinner is good for you.晚饭后散步对你有益。 跟踪练习 Eating vegetables is good_____________ your health. 5. And twenty percent do not exercise at all!还有20%的学生从来不锻炼！ not...at all 意为“一点儿也不”not和be动词，助动词或情态动词连用。如： （1）The story isn't interesting at all.那个故事一点儿也不有趣。 （2）They didn't enjoy the vacation at all.他们一点儿也不喜欢那个假期。 （3）He can't use the computer at all.他一点儿也不会用电脑。 跟踪练习 他一点儿也不觉得累。 _________________________________________________________ 6.The answers to our questions about watching television were also interesting. 对我们提出的有关看电视的问题的回答也颇有意思。 the answers to the questions 意为“问题的答案”，介词用 to,不用of。to在这里为介词，意为“指向；对于；针对”。类似的短语还有：the key to the door 门的钥匙；the way to the zoo去动物园的路。如： Do you know the answer to the question?你知道这个问题的答案吗? 跟踪练习 Mike, do you know the answer__________Question 4? It's a little difficult for me. 7.Although many students like to watch sports, game shows are the most popular. 虽然许多学生喜欢观看体育节目，但游戏类节目却是最受欢迎的。 although是连词，用来连接主从复合句，表示让步关系，意为“虽然；即使；尽管”。在一句话中，只能用一个连词连接主从复合句，用了although就不能再用but。如： Although she was tired, she went on working.=She was tired, but she went on working. 虽然她很累，但她还是坚持工作。 跟踪练习 We lost the game,____________everyone played well.（用适当的连词填空） 8.It is good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise.通过上网或看游戏类节目放松是很好的，但是我们认为最好的放松方式是通过锻炼。 （1）It is+adj.+(for sb.) to do sth.是一个固定句型，意为“（对于某人来说）做某事是……的”。 （2）do sth.by..意为“通过……来做某事”，此处的by意为“通过”。如： We need to get good grades by working hard.我们需要通过努力学习来取得好成绩。 （3）through意为“以；凭借；通过”。through还有“穿过”之意。如： ①He got the job through his friend.他通过他的朋友得到了这份工作。 ②The river runs through the village.这条河流流经那个村庄。 跟踪练习 ①Nowadays it's very common____________（网购）among young people. ②We'd better tell him the date of exams_________（通过……谈论）on WeChat. ③It's his dream to swim___________ the Yangtze River one day.（across或through） ④We helped her get out___________the back door.（across或through） 9.It is healthy for the mind and the body.它有益于身心健康。 mind意为“头脑；心智”，常见短语有：change one's mind 改变主意，make up one's mind to do sth.下决心做某事。如：No matter what you may say, I won't change my mind.不管你可能会说什么，我都不会改变主意。 知识拓展：mind 还可以作动词，意为“介意；反对”，其后跟名词、代词或动名词作宾语，也可跟条件状语从句。如： （1）Would you mind closing the window?请关一下窗户好吗? （2）Do you mind if I close the window?我把窗户关上，你介意吗？ 跟踪练习 ①I made up my mind_____________(wait) for her. ②I don't mind______________(wait) here for a long time. 语法提优 频度副词 教材例句 1.I usually watch TV. 2.I always exercise. 3.She sometimes goes shopping. 4.No, I never go shopping. 1.概念 频度副词是用来表示动作发生频率的词。常用来表示不确定时间，主要包括 always，usually， often,sometimes,hardly(ever),never等,如果表示具体频度次数，可采用次数加单位时 间。如：once a week一周一次 twice a month一月两次 2.常用频度副词的区别 always意为“总是；永远”，表示频度最高。 usually意为“通常地”，即很少有例外，多用于一般现在时。 often意为“经常”，在频度上不如usually 那么频繁。 sometimes 意为“有时；偶尔”。 hardly ever 意为“几乎从不”，表示否定意义。 never 意为“从来没有；绝不”，表示否定意义。 以上几个频度副词所表示的频度，从高到低为：always→usually→often→sometimes→hardly→ever→never 3.频度副词在句子中的位置 在句子中，频度副词常放在实义动词前面，be动词、情态动词和助动词后面。如： He always helps others.他总是帮助别人。 4.对句子中频度副词进行提问，用“how often”。如： ---How often does he watch TV?他多久看一次电视? ---He sometimes watches TV.他偶尔看一次电视。 语法精练 一、用括号中所给词的适当形式填空 1.
