Its full _ water.A. with B. in C. of D. at答案：C思路分析：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”。3. maybe adv. 或许；大概；可能【用法】常位于句首表推测。【例句】Maybe that man is a policeman. 或许那人是警察。【辨析】maybe 和may be【考题链接】The boy may be his brother. （同义句转换）_ the boy _ his brother.答案：Maybe; is4. health n. 健康；人的身体（或精神）状态【用法】不可数名词。【例句】I think health is more important than money. 我认为健康比金钱更重要。【拓展】be in good/poor health 身体状况好/ 不好healthy adj. 健康的unhealthy adj. 不健康的【例句】My grandparents are both in good health. 我祖父母的身体都很好。We should eat healthy food. 我们应当吃健康的食物。【考题链接】Cola is _, and its not good for your _.A. healthy; health B. unhealthy; healthyC. unhealthy; health D. health; health答案：C思路分析：后一空前是your，形容词性物主代词，故后接名词；根据句意“它对你的健康不利”可知“可乐是不健康的”，故选C项。5. die v. 消失；消灭；死亡 【用法1】作“死亡”讲，是不及物动词，不能用于被动语态，是瞬间动词，不能与表示一段时间的状语连用。【例句】 His grandfather died five years ago. 他祖父五年前去世的。 【用法2】die可以用于进行时态，表示“即将死去，奄奄一息”。 【例句】He is dying. 他快要死了。 【拓展】dead 死的，是die的形容词形式。可作表语或定语。作表语时，表示状态。 death 死亡，是die的名词形式。 【例句】His dog has been dead for two weeks. 他的狗已死了两周了。His mothers death made him very sad. 他母亲的去世使他非常难过。【考题链接】Did the bird _?No, but it _.A. die; dying B. dead; deathC. die; is dying D. death; is dying答案：C思路分析：浏览题干可知问句是以助动词Did开头，其后接动词原形，故排除B，D两项；根据句意“这只鸟死了吗？没有，但是它快要死了。”可知，用现在进行时。6. however adv. 然而；不过 【用法】表示转折。【例句】He said that it was so, however, he was wrong. 他说事情是这样的，然而他错了。【拓展】however adv. 无论如何；不管怎样，相当于no matter how。【例句】However difficult it is, I want to have a try. =No matter how difficult it is, I want to have a try.不管多么难，我都想试一试。【辨析】however和but二者都有“然而；但是”之意，具体用法不同。however副词，可以放在句首、句中或句末，置于句中时，前后通常用逗号隔开。He wanted to go to the shopping mall, however, he didnt go at last. 他想去购物中心，但最后还是没去。but并列连词，常位于句中，引领一个表示转折关系的并列句。Mike is young, but he can do it well.迈克虽然年龄小，但是他能做好那件事。【考题链接】Those two girls are twins, _, they look very different.A. although B. but C. however D. because答案：C思路分析：根据句意“那两个女孩是双胞胎，但是，她们看起来很不同”可知前后表示转折；空后有逗号隔开，故选C项。【即学即练】根据句意和汉语提示完成句子1. _（可能）I can go swimming tomorrow.2. He visits his mother _（两次）a week.3. My bag is _（满的）of books.4. Its good for your _（健康）to eat more fruit.5. My pet dog _（死）last week.6. _（然而）, we dont have the same idea.答案：1.

He knows five languages _ English and Japanese. A. are like B. such as C. such like D. as such答案：B思路分析：A项意为“像”；C项错误；D项错误；句意为“他懂五种语言，例如英语和日语”。2. Can you believe that in _ a rich country there should be _ many poor people?A. such; such B. so; so C. such; so D. so; such答案：C思路分析：a rich country意为“一个富有的国家”，用such修饰；many要用so修饰。句意为“你能相信在这么富有的一个国家里有如此多的穷人吗？”3. more than 多于【用法】常用在数词之前，表示数量超过多少，同义词是over。其反义短语是：less than。【例句】She sleeps more than/ over nine hours every day. 她每天睡觉达九个多小时。【考题链接】We stayed in the countryside for _ than three weeks.A. taller B. more C. better D. bigger答案：B思路分析：three weeks意为“三周”；A项意为“更高的”；C项意为“更好的”；D项意为“更大的”，均不符合句意；more than three weeks意为“三周多”。【即学即练】根据汉语意思完成下列句子1. 他早餐吃了一些水果，例如香蕉和橙子。He ate some fruit _ _ bananas and oranges for breakfast.2. 你至少一周应该锻炼两次。You should exercise _ _ twice a week.3. 昨天我休息了三个多小时。Yesterday I rested for _ _ three hours.4. 看！我的苹果不到五个。Look! I have _ _ five apples.答案：1. such as 2. at least 3. more than 4. less than四、重点句型【句型学习】1. How often do you exercise? 你多久锻炼一次？【句析】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。回答应是频率副词或表示频率的词组，如always, usually, often, sometimes, hardly, ever, never, every day, once, once a week, three times a day等。【例句】How often do you go to the movies? 你多久去看一次电影？Once a week. 一周一次。【考题链接】_ do you have an Art Festival in your school?Once a year.A. How long B. How often C. How far D. How soon答案：B思路分析：考查疑问词的用法。从答语来判断，应用how often，意为“多久一次”；how long意为“多久；多长”；how far意为“多远”；how soon意为“多久以后”。2. She says its good for my health. 她说它对我的健康有益。【句析】本句是一个含有省略that的宾语从句的复合句。She says 是主句，其后省略了that, its good for my health作says的宾语。be good for 对有益【例句】Exercise is good for you. 锻炼对你有益。【拓展】be good at 在方面做得好；擅长；be good with 与相处融洽；be good to 对友好【例句】He is good at learning languages. 他擅长学习语言。The teacher is good with his students. 这位老师和他的学生相处融洽。My new deskmate is good to me. 我的新同桌对我很友好。【考题链接】Are the sunglasses good _ eyes?A. to B. with C. for D. at答案：C思路分析：be good for eyes意为“对眼睛有益”，故选C。3. Although many students like to watch sports, game shows are the most popular.尽管许多学生喜欢体育节目，但是游戏节目仍然是最受他们欢迎的。【句析】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不能同时出现在同一个句中，即二者只能取其一。【例句】Although he is tired, he didnt stop to have a rest. =He is tired, but he didnt stop to have a rest. 尽管他累了，但他没有停下来去休息。【考题链接】_ she is young, _ she knows a lot.A. Although; but B. Though; but C. Although; / D. /; /答案：C思路分析：although/though和but不能同时用在一个句子中，故排除A，B两项；D项不能表达原句句意；C项符合。句意为“虽然她年轻，但是她知道的很多”。【即学即练】单项选择1. Do you think the best way to relax is _ exercise?A. though B. through C. over D. across2. You bought the car about ten years ago?Yes. _its old, it still runs well.A. Because B. Since C. Although D.

B思路分析：1. 考查介词的用法。句意为“你认为放松的最好办法是通过锻炼吗？”，此处through是“通过；凭借”之意。A项是连词；C项意为“跨越”；D项指从表面穿过。2. 考查连词的用法。because意为“因为”；since意为“既然；自从”；although意为“尽管”；but意为“但是”。根据句意应选C项。3. 考查疑问词的用法。从答语来判断，应用how often，意为“多久一次”；how long意为“多久；多长”；how far意为“多远”；how soon意为“多久以后”。4. 考查介词短语的用法。be good for 对有益；be good at 在方面做得好；擅长；be good with 与相处融洽；be good to 对友好；根据句意“我弟弟擅长打篮球”可知B项正确。【课文领读】What Do No. 5 High School Students Do in Their Free Time?Last month we asked our students about their free time activities. Our questions were about exercise, use of the Internet and watching TV. Here are the results.We found that only fifteen percent of our students exercise every day. Forty-five percent exercise four to six times a week. Twenty percent exercise only one to three times a week. And twenty percent do not exercise at all!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. Most students use it for fun and not for homework.The answers to our questions about watching television were also interesting. Only two percent of the students watch TV one to three times a week. Thirteen percent watch TV four to six times a week. And eighty-five percent watch TV every day! Although many students like to watch sports, game shows are the most popular.It is good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise. It is healthy for the mind and the body. Exercise such as playing sports is fun, and you can spend time with your friends and family as you play together. And remember, “old habits die hard”. So start exercising before its too late!Units 1-2语法归纳一、预习新知1. 不定代词的用法2. 频度副词的用法二、预习点拨思考问题一：表示人的不定代词有哪些？思考问题二：表示物的不定代词有哪些？思考问题三：频度副词的位置一般在哪里？（答题时间：40分钟）上册Unit 2 How often do you exercise?重点单词. 单项选择1.
