(1) on weekends/on the weekend在周末 (2) go to the movies 去看电影 (3) 第一个do 助动词 第二个do 实意动词 2. hardly ever 几乎从不 hardly ever 相当于 hardly, ever起强调作用。 hardly 为副词，意为“几乎不没有）”，相当于almost not，本身具有否定含义，不能再使用其他否定词。 She hardly eats anything. 辨析: hardly 和hard hard作形容词，意为“困难的，艰苦的，硬的”； hard作副词，意为“努力地，猛烈地”。 hardly意为“几乎不” (1) The ground is too to dig (2) I can understand them. (3) It's raining ,the people can go outside. 3. ----How often do you watch TV? ----Twice a week. (1) how often 意为“多久一次，多长时间一次”，用来提问频率。 (2) twice a week 一周两次 【解析】本句是含有特殊疑问词how often 的特殊疑问句。 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。 how often: 多久一次，用来提问在某一特定时间内进行某个动作的次数，答语有never, sometimes, often, usually, always, three times a year等。 how long: 多长时间， 用来对“for + 一段时间”提问，强调时间的延续，其谓语动词应为延续性动词；此外，还可用于询问物体的长度。 how soon: 需要多长时间，过多久才……答语有in a week/ month/ year等。 how far：多远，用来询问距离，答语常用“数字 + miles/ kilometers”等。 拓展: 一次 once 两次 twice 三次或三次以上 基数词+ times three times four times 4. What's your favorite program? = What program do you like best? 你最喜欢的节目是什么？ 5. How come?怎么回事？怎么会？ 表示某件事情很奇怪，有点想不通；可单独使用，也可引导一个问句。相当于疑问词why。但how come 开头的特殊疑问句使用的仍是陈述语序。 How come you didn't tell me about it? = Why you didn't tell me about it? 6. I go to the movies maybe once a month. 我也许一个月去看一次电影。 maybe 副词，意为“或许，大概，可能”，常位于句首。 Maybe he knows the way to the park. 辨析：maybe 与 may be maybe副词，作状语，意为“或许，大概，可能”，常位于句首。 may be 属于“情态动词+be 动词”结构，意为“可能是”。 (1) The baby is crying she is hungry. (2) The woman a teacher . 7. Last month we asked our students about their free time activities. ask sb. about sth. 询问某人某事 8. We all know that many students often go online, but we were surprised that ninety percent of them use the Internet every day. The other ten percent use it at least three or four times a week. 我们都知道许多学生经常上网，但是让我们感到惊讶的是90%的学生每天都上网，而另外10%的学生一周至少上网达三至四次。 (1) other: adj. 其他的+名词 the other: adj. 其他的+名词(在特定的范围内) one?the other? 一个??另一个 One of them is blue，the other ones are purple. others: 其他的东西 the others: 其他的东西(在特定的范围内) One of the children likes reading，the others like singing. 后句可替换为the other students like singing.

Although many students like to watch sports, game shows are the most popular. 尽管许多学生喜欢看体育节目，但是娱乐节目是最流行的。 12. It is good to relax by using the Internet of watching game shows, but we think the best way to relax is through exercise. 通过使用因特网看娱乐节目来放松很不错，但是我们认为最好的放松方式是通过锻炼来放松。 (1) It’s +adj.+to do sth 做某事??的 It’s very easy to learn English well. (2) by doing sth. 通过做某事 (3) the best way to do sth. is做某事的最好方式 13. It is healthy for the mind and the body. 这有益于身心健康。 stay healthy = keep healthy = keep in good health 保持健康 下面是申申老师对本单元语法知识拓展讲解: 1. 频度副词的含义 表示次数、频率的副词称为频度副词。 常用的频度副词按高低依次为 always > usually > sometimes > seldom > hardly ever > never 100% 80% 60% 30% 10% 0% 2. 频度副词在句中的位置 (1 )频度副词一般在实意动词之前，be 动词、助动词或情态动词之后 E.g. We never eat junk food. Lucy is sometimes very busy. I can hardly say a word. (2)有些频度副词也可位于句首，但表示不同含义 sometimes 常位于句首，和位于句中区别不大。 Sometimes Jack plays computer games. often 用于句首时，通常表示强调，且其前一般有quite，very 修饰 Very often he goes online. Usually 也可位于句首，其前不用修饰语。 Usually my father goes up early. Always 一般不用于句首，但可以用在祈使句中。 Always remember this. 2. Hmm...next week is quite full for me，Jack.呣……下周我很忙，杰克。 【解析】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 people. 公共汽车里挤满了人。 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？ 3.She sometimes goes shopping. 她有时去购物。 【解析】sometimes为频度副词，意为“有时候”，多用于一般现在时或一般过去时中。 辨析： sometimes, sometime, some time与some times Sometimes意为“有时”，可放于句首或句中。（How often提问） Sometime表示在某个时间段内的某个时候，既可以表示过去某个时间也可以表示将来的某个时间。（When提问） Some time 名词性短语，意为“一些时间”，time是不可数名词，意为“时间”。 （How long提问） Some times表示“几次”，time是可数名词，表示“次；次数”。 （How many times提问） Even friends sometimes disagree. 即使是朋友，有时也会意见不合。 I hope to see you again sometime next year. 我希望明年的某个时候能再见到你。 Please give me some time to red this passage.请给我一些时间看这篇文章。 I have been to Beijing some times before. 我以前去过北京几次。 4．He plays at least twice a week.他至少一周踢(足球) 两次。 【解析】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. 他至少应该说声谢谢。 5．She says it's good for my health. 她说它对我的健康有益。 【解析】be good for 对……有益 Exercise is good for you. 锻炼对你有益。 be good at 在……方面做得好；擅长…… He is good at learning languages. 他擅长学习语言。 be good with 与……相处融洽 The teacher is good with his students. 这位老师和他的学生相处融洽。 be good to 对……友好 6.My new deskmate is good to me. 我的新同桌对我很友好。 health n. 健康，是不可数名词。 I think health is more important than money. 我认为健康比金钱更重要。 be in good/poor health 身体状况好/不好 My grandparents are both in good health. 我祖父母身体都很好。 healthy adj. 健康的 We should eat healthy food. 我们应当吃健康的食物。 unhealthy adj.不健康的 Junk food is unhealthy. 垃圾食品是不健康的。 7.How many hours do you sleep every night？你每天晚上睡几个小时？ 【解析】how many 和how much how many和how much都可以表示“多少”，但how many后接可数名词复数，而how much后接不可数名词。 How many girls can you see? 你能看见多少个女孩？ How much milk do you want? 你想要多少牛奶？ 8．Although many students like to watch sports，game shows are the most popular.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。 【解析】本句是复合句，although many students like to watch sports是让步状语从句。 although conj. 虽然；尽管；即使 相当于though，引导让步状语从句。 在英语中，although(though)和but不能连用在同一个句中，即二者只能取其一。 .
