6、how often 的特殊疑问句。【解读】how often 多久一次，用于对动作发生的频率进行提问。回答应该是频度副词或表示频率的词组，如always，usually，often，sometimes，hardly，ever，never，every day，once a week，three times a day等。How often do you go to the movies?你多久去看一次电影？Once a week.一周一次。【例题】_ do you practice English?Every day.AHow long BHow oftenCHow old DHow soonA

7、多长时间；多长(指长度)B多久一次C多大岁数D多久句意“你多久练习一次英语？” “每天。”2.What do you usually do on weekends？周末你通常干什么？【解读】本句是主语为第二人称的一般现在时的特殊疑问句，询问在现在一段时间内经常或习惯做的事情。其结构为：What do you动词原形其他？若主语为第三人称单数时，特殊疑问句结构为：特殊疑问词(组)does主语动词原形其他？What do you often do on Mondays?星期一你通常干什么？I often play soccer with my friends.我通常和朋友一起踢足球。【解读】usu

8、ally adv.通常，表频率。一般情况下，usually多用于一般现在时态中。I usually do my homework after supper.我通常在晚饭后做作业。【注意】表频率的副词一般放在行为动词之前，be动词、助动词或情态动词之后。【拓展】usual adj. 通常的，平常的He always does that in the usual way.他总是用惯常的方式做那件事情。【例1】When _she usually exercise?In the morning.Ado BdoesCdid Dis解析由usually 可知用一般现在时，故排除C项；由主语she是第三人称

9、单数可排除A项；由exercise是动词原形可排除D项。答案B句意“她通常什么时候锻炼？”“在早上。”【例2】 I _ shop on Saturdays.Afinally BalmostCusually DnearlyA最终B几乎C通常D几乎，差不多句意我通常在星期六去商店购物。3twice a week一周两次【解读】twice adv. 两次We have Chinese twice a day on Friday.周五我们一天上两节语文课。当提问twice时，可以用疑问词how many times(多少次)，但不能用how often 提问。how often 可提问twice a

10、week.How many times have you watched the program?这节目你看了多少次？How often do you watch the program?你多久看一次这个节目？【注意】英语中，once表示“一次”，twice表示“两次”，从“三次”起用“基数词times”表示次数。three times三次，five times五次。【例1】The Smiths go to Australia _ a year.Aone BtwoCthree Dtwice解析one，two，three 是基数词，后应直接接名词，而year 前有冠词，twice表示“两次”。答

11、案D句意史密斯夫妇一年去澳大利亚两次。【例2】对画线部分提问I went to Hainan twice last year._点拨：画线部分表示的是次数，那么就应该用询问次数的疑问词how many times 来提问。答案：How many times did you go to Hainan last year?4.Hmm.next week is quite full for me，Jack.呣下周我很忙，杰克。【解读】full adj. 忙的；满的；充满的常用短语为be full of.，意为“充满”；反义词是empty，意为“空的”。The bus is full of peopl

12、e.公共汽车里挤满了人。【拓展】full adj. 吃饱的；过饱的，其反义词是hungry，意为“饥饿的”。Are you hungry or full？你饿了还是饱了？【例题】There is a glass on the table. Its full _ water.Awith BinCof Dat点拨：本题考查full的用法。be full of意为“充满”，故用介词of。句意为“桌子上有一个玻璃杯。它装满了水”。答案：C5I go to the movies maybe once a month.我可能一月去看电影一次。【解读】maybe adv. 大概；或许；可能Maybe tha

13、t man is a policeman.或许那人是警察。【辨析】maybe 和may bemaybe副词，意为“或许；大概”，常位于句首表推测。Maybe he is at Jims home.或许他在吉姆家。may be由情态动词may和 be构成，意为“可能”，在句中作谓语。He may be right.他可能是对的。【例题】_ Li Hua wants to be an astronaut like Yang Liwei.AMay be BMayCAlso DMaybe解析首先看句子，A项可作谓语，B项与动词连用构成谓语，本句不缺少谓语，故排除A、B两项；C项不放在句首，而是置于系动

14、词、助动词、情态动词后，实义动词前，故排除。答案D句意或许李华想成为像杨利伟那样的宇航员。6He plays at least twice a week.他至少一周踢(足球) 两次。【解读】least adv.最小；最少adj.& pron.最少的；最小的，它是little的最高级。He has least money of all of us.在我们所有人中他的钱最少。She works least.她工作最少。We have least time.我们时间最少。at least 至少；不少于；起码，其反义短语为：at most 至多At least he should say thanks

15、.他至少应该说声谢谢。【例题】There are _ three thousand people in the park.Aat first Bat lastCat least Dat the least点拨：A项意为“首先”；B项意为“最后”；C项意为“至少”；D项短语有误。句意为“在公园里至少有三千人”。答案：C语法频度副词我们平时会这样说：你经常去看电影吗？ 他有时来我家玩。我一周给他写一封信。我从来没有去国外旅行过等等。诸如“经常，有时，一周一次，从来没有”这样的词在英语中叫频度副词。频度副词表示什么呢？频度副词表示行为动作的频率，本单元中我们接触的主要是频度副词，按其频率发生的高低分

16、别是：always 总是； usually 通常；often 经常； sometimes 有时；hardly ever 几乎不；never 从不。基本用法：1频度副词表示经常性的动作或情况，常和一般现在时连用，表示现在经常或反复发生的动作。They always go to the park by bus.他们总是乘公共汽车去公园。2频度副词一般放在系动词be、助动词、情态动词之后，实义动词之前。Kate is often late for school.凯特经常上学迟到。3对这些频度副词进行提问时，用特殊疑问词how often，意为“多久一次”。I sometimes_ watch TV

17、programs.(对画线部分提问)How often do you watch TV programs?你多久看一次电视节目？【例1】I hope _ to see him again.Aever BoftenCalways DneverA曾经 B经常C总是D从来不句意我希望再也不要见到他。【例2】How often do you visit your grandparents?_.AFor a week BOnce a weekCIn summer vacation DOn Friday解析由问句中的how often知应该用表示动作频率的单词或短语回答。for a week“ 一周”，表

18、示一段时间；in summer vacation“在暑假”；on Friday “在周五”，都是回答某个时间，故排除A、C、D三项。答案B句意“你多久去看望一次你的祖父母？”“一周一次。”【例3】My mother hates cyber bars(网吧)She _allows(允许)me to go in.Aonce BneverCoften DalwaysA一次 B从来不C经常D总是句意妈妈讨厌网吧。她从不允许我进入。Section B & Self Check课文翻译Section B 2bWhat Do No.5 High School StudentsDo in Their Free

24、于看电视这个问题的答案也很有趣。仅仅2%的学生一周看13次电视。13%的学生一周看46次。并且85%的学生每天都看电视。尽管许多学生喜欢观看体育节目，但是游戏节目仍然是最受他们欢迎的。尽管上网或观看游戏节目对放松很有好处，但是我们认为锻炼是最好的放松方式。锻炼使我们的大脑和身体更加健康。像参加体育运动这样的锻炼是有趣的，并且你可以与你的朋友和家人一起花费时间进行锻炼。请记住：“旧习惯是很难摈弃的。”所以我们要在身体还很健康的时候就开始锻炼。知识详解1She says its good for my health. 她说它对我的健康有益。【解读】本句是一个含有省略that的宾语从句的复合句。Sh
