What’s your favorite…..? 你最喜欢的……是什么？11 start doing sth. 开始做某事 12. the best way to do sth. 做某事的最好方式词汇精讲1. maybe maybe是副词，意思是“也许，可能”，在句中作状语，相当于perhaps，常位于句首。 例如：Maybe she’ll come this afternoon. 她可能今天下午来。 Maybe you put the letter in your pockets. 大概你把信放在衣袋里了。 【拓展】I can’t find my watch. ____________________ in your pocket. 我找不到我的手表了，它可能在你的口袋里。 ______________________________ 他可能是军人。 （2）maybe和may be可相互转换。 例如：He may be in the office. = Maybe he is in the office. 他或许在办公室。 You may be right. = Maybe you are right. 你或许是对的。2. although 相当于though，意为“尽管，虽然”，用来引导让步状语从句。它所引导的从句不能与并列连词but; and; so等连用，但可以和yet; still等词连用。例如： Although he lives alone, he doesn’t feel lonely. = ___________________________________________ 虽然他一个人住，但他并不感到孤独。There is air all around us, although we cannot see it. 虽然我们看不见空气，但空气却存在于我们的周围。【拓展】although与though的辨析：（1）用作连词，表示“虽然”，二者可以互换使用，但although比though更为正式。 Though/Although it was raining, we still went there. 虽然下着雨，但我们还是去了那里。（2）although一般不用作副词，而though可用作副词，且一般放在句末（不放在句首），意为“可是，不过”。例如：It’s hard work; I enjoy it, though. 工作很辛苦，可是我很喜欢。We all tried our best. We lost the game, though. 我们都尽了最大努力，但我们还是输了。（3）在as though(好像，仿佛)，even though(即使，纵然)等固定短语中不能用although。例如： He talks as though he knows everything. 他夸夸其谈，好像无所不知。3. die die是动词，意为“死亡”，是短暂性动作，常用于过去时中，过去式为died。例如：Plants and people will die without water. 没有水，植物和人都会死。His father died two years ago. 他的父亲两年前去世的。【拓展】die有多个变形词：例如：The tree has been dead for ten years. 这棵树死了10年了。 She looked at her _____ cat sadly. 她伤心地看着她死去的猫。 My grandpa _________ two years ago. 我爷爷两年前去世了。 The fish will ____without water. 鱼离开水会死去。 Car accidents have caused a lot of ________. 车祸造成很多人死亡。 The doctors have saved the _________man. 医生们救活了那个垂死的人。4. however＆but however和 but都意为“可是，但是”；但是用法不同。 （1）however不能直接连接两个分句，必须另起新句，并用逗号隔开。例如：It was raining hard. However, we went out to look for the boy. 雨下得很大，然而我们还是出去寻找那个孩子。 （2）but是并列连词，连接两个并列分句，后面不用逗号，前后两句在总的意义上构成了对比。例如：I really don't like cheese, but I will try just a little this time.我实在是不喜欢吃奶酪，但是这次我要尝一点。 （3）however比but用的场合更正式, 因此however用于书面语,而but 常用于口语。另外, however的意思还不只局限于“但是;然而”，它还有其他的用法。例如： However hard I worked, she was never satisfied. 无论我多么努力地工作，她从来没满意过。 However did you get here without a car? 没有汽车你究竟是怎样来的呢?5. hardly＆hard hardly和hard形式上很接近，但意义截然不同。 （1）hardly是表频率的副词，意为“几乎不；几乎没有”，相当于almost not。例如：There is hardly any coffee left. = There’s almost no coffee left. 几乎没有剩余的咖啡了。 （2）hard作形容词时，意为“困难的；硬的；勤奋的；严厉的；苛刻的”。hard作副词时常用来表示程度，意为“努力地；猛烈地；剧烈地”。例如：This ground is too hard to dig. 这块地太硬，挖不动。They tried hard to succeed. 他们努力工作，以求得成功。【拓展】常见的表示频度的副词： （1）always 的频度为100%，表示动作重复、状态继续，中间没有间断，意思是“总是”、“永远地”。例如：The sun always rises in the east and sets in the west. 太阳总是东升西落。（2）usually 的频度为70%左右，意为“通常”、“平常”，即很少有例外。例如：He usually goes to bed at ten o’clock. 他通常10点钟睡觉。（3）often 的频度为50%左右，意为“常常”，但不如usually那么频繁，表示动作重复，中间有间断。例如：He is often late for school. 他上学经常迟到。 （4）sometimes 的频度为20%左右，意为“有时”，表示动作偶尔发生。可以位于句首，以示强调。例如：It is sometimes hot and sometimes cold. 天气忽冷忽热。（5）hardly ever 的频度为5%左右，意为“几乎不”、“偶尔”。例如：I hardly ever go out these days. 这些天我几乎不出门。（6）never 的频度为0，意为“从来不”、“永不”。 例如：　　 My parents are never late for work. 我父母上班从来不迟到。6. exercise 　 （1）作不及物动词，意为“锻炼、运动”。例如：－How often do you exercise? 你多久锻炼一次？　　 －I exercise every day. 我每天都锻炼。 （2）作不可数名词，意为“锻炼、运动”，常与动词take连用。（3）作可数名词，意为“练习；操”。We do morning _______________every day. 我们每天做早操。___________makes me keep healthy. 运动使我保持健康。We do English __________to help us learn English well. 我们做英语练习以便学好英语。　 7. healthhealth为名词，意为“健康”，其形容形式为healthy，意为“健康的”。unhealthy意为“不健康的，是healthy的反义词。healthily是“健康地”，是副词。在名词词尾加y构成形容词，类似的词还有：rain—rainy 雨—下雨的 sun—sunny 太阳—晴朗的 luck—lucky 幸运—幸运的 wind—windy 风—刮风的8. once / twice once“一次”，twice“两次”，在英语中三次或三次以上通常用“基数词+times”表示，time在这里为可数名词，意为“次数”，复数加s。例如：I wash my face twice a day. 我每天洗两次脸。He has been there four times. 他去过那里四次。 9.mind n. 头脑，心智eg. Playing chess is good for your mind and body. mind v. 介意 常用在句型would you mind sth./ doing sth? 你介意（做）某事吗？eg. Would you mind moving your bike? 【练习】Would you mind not _______ ?

She says it’s good for my health.be good for意为“对……有好处，对……有益处”，介词for后接名词或代词。其反义词为be bad for，意为“对……有害处”。例如： ___________________________________垃圾食品对我们的健康没有好处。 ___________________________________________吸烟对你有害。【拓展】（1）be good to“对……好”，其反义短语为be bad to“对……不好”。介词to之后一般接表示人的名词或代词。例如：She is very good to us. 她对我们很好。The boss is bad to his workers.那个老板对他的工人不好。（2）be good at“在……方面擅长”，介词at后面常接名词、代词或动词-ing形式，同义短语为do well in。例如：She is good at English and Chinese. = She does well in English and Chinese. 她擅长英语和汉语。（3）be good with“和……相处得好；擅于和……相处”。例如： Are you good with children?你和孩子们相处得好吗？4. It is good to relax by using the Internet or watching game shows… It is/was + adj. + to do sth. 意为“做某事是……的”，to do sth.为句子的真正的主语，而it为形式主语，形式主语不能用别的词来代替，句中可在形容词后加for sb.，意为“对于某人来说，做某事是……的”。例如： ___________________________________________对我们来说，学习一门外语是相当重要的。 ____________________________________________ 对我们来说，多吃蔬菜和水果是必要的。【拓展】 这个句型中的for sb.有时也可以用of sb. 二者意义有区别： （1）在It’s + adj. + for sb. to do sth. 中，for sb.意为“对某人来说”，句中的形容词是用来说明to do sth.的，形式主语只能用it。 （2）在It’s + adj. + of sb. to do sth. 中of sb. 意为“某人……”，句中形容词可与逻辑主语sb. 构成系表结构，即形容词是用来说明或形容sb.（某人）的 It’s very kind_________ you to help us. It’s necessary _______the students to do some housework. 5.

A how often“多久一次”，提问频率；how old “多大”，提问年龄；how many“多少”，提问可数名词的数量；how much“多少钱；多少”，提问物品价格或不可数名词的量。由答语“几乎从不”可知此处提问频率，故用how often。3. A always“总是”；sometimes“有时”；hardly“几乎不”；never“从不”。由上句句意“林老师很受学生们的欢迎”可知，本句句意为“她的课总是生动有趣”，故always符合句意。4. A 由常识可知，英国人从不在男子的名字前用Mr.。never意为“从不”，故选A。5. A 由答语第二句句意“我一点儿也不喜欢钓鱼”可知前面应是表否定意义的词，故选A。6. C usually通常；almost几乎；hardly几乎不；nearly将近。由上句句意“请大声说”可知是“我几乎听不见你说话”，故选C。 7. D 由答语句意“每周一次”可知，问句询问动作发生的频率，所以用how often。8. A 频度副词要放在连系动词、助动词、情态动词之后，实义动词之前。be late for迟到。9. B 由后句句意“他喜欢使用网络”及选项可知，上句句意为“张浩几乎从不看电视”。hardly ever是固定短语，意为“几乎从不”。hardly ever表示否定含义，前面不能再加表示否定的doesn’t。故选B。10. C 本题考查反义疑问句。hardly几乎不，表示否定，因此后半句应该用肯定形式。时态是一般现在时，因此选C。Unit 2 How often do you exercise? 语法练习------ ______ do I need to feed the pet dog?------ Twice a day .A . How long B . How much C . How soon D .
