5、申science fiction 科幻小说；top science 尖端科学2History n历史，历史学：Chinese history 中国历史；in history 在历史上记忆法his + story，字面意思为“他的故事”，引申为“历史”。引申modern history 近代史；ancient history 古代史。 3Favorite n最喜爱的人或物：He is a favorite with his uncle他是他伯父最喜欢的人。adj喜爱的记忆法favor和favorite联系记忆。引申同义词：nbeloved，dear，preference，adjdearest，e

6、steemed，preferred；反义词：npet-hate adjhatred。the favorite 热门，最有可能获胜的。4Teacher n教员，老师引申王老师不能说teacher Wang，而应说Mr(Miss，Mrs)Wang，王教授应该为Professer Wang。5Because conj因为记忆法be + cause “be”意思为“是”，“cause”意思为“原因”，be + cause则是“是的原因”，即“因为、由于”之意。考点短语because of 因为、由于，后面直接接名词或动名词：Because of the bad weather，they have to

9、gyn生物学记忆法bio + logy，“bio”前缀译为“生活的，生物的”，“logy”后缀，译为“某门学问”。bio + logy则为“生物的学问”即“生物学”。引申sociology 社会学。基本句型1Whats your favorite subject？你最喜欢什么科目？favorite adj特别喜爱的，如：a favorite song 一首喜爱的歌，his favorite daughter 他最疼爱的女儿，my favorite lesson 我最喜欢的功课。注：favorite与like汉语均有“喜爱”的意思，但他们的词性不同，在句子中所处的位置也不同。试比较：He lik

10、es playing football very much他非常喜欢踢足球。(like在主语后作谓语)Football is his favorite sport足球是他喜爱的运动。(favorite在名词前作定语)句中favorite本身就含有“最”的意思。因此，它没有比较等级。类似的问题有Whats your favorite fooddrink？回答时就说：My favorite fooddrink is.很喜爱like.very much like.a lot2Its Tuesday，November 11今天是11月11日，星期二。句中的It通常用来指代时间日期，询问星期通常用“Wh

11、at day is today？”。英语中表示星期名称的单词，第一个字母应大写，且都以-day结尾。按西方风俗，一周的第一天为星期天“Sunday”，而不是星期一“Monday”。英语中表示月份名称的单词，第一个字母都应大写，且前面不加冠词。在表达日期概念时通常先写月后写日，且日多用序数词来表达，即在基数词后面加上th。但并不是所有的基数词变序数词都在后面加th，请记住下面的顺口溜：1，2，3特殊记，8去t，9减e，ve变f再加th，遇y变ie再加th。3Why do you like PE？你为何喜欢体育课？Because its fun因为它有趣。(1)疑问词why用来提问原因，往往用表示

12、原因的because从句回答。如：Why are you late for work？你今天为什么上班迟到了？Because the traffic is too bad因为交通太糟糕了。because因为，是一个连词，它的后面必须是一个从句。如：He doesnt go to school today because he is ill今天他没来上学，因为他病了。(2)fun作形容词，译为“有趣的，愉快的”(美)。如：You are great fun你真有趣。We have a fun holiday我们假日过得很愉快。fun还可作名词(不可数)，译为“玩笑，娱乐，嬉戏”或“有趣，有趣的人

13、或事(此时不加a)”。如：Playing computer games is great fun玩电子游戏很有趣。(3)PE= physical education 体育课。4After class I have volleyball for two hours课后我打两个小时的排球。(1)after class“课后”。注意class前不加冠词。(2)此处“have”表示“从事，进行(由后接的名词所表示的动作)”，如：have a swim 游泳have a walk 散步have 的应用很广泛，在不同的场合有不同的意思，可译为“有、吃、喝、开、举行、上”等。如：I have a child

14、我有一个孩子。have breakfastlunchsupper 吃早饭午饭晚饭have a cup of tea 喝杯茶have some fruit 吃些水果have a meeting 开会have a sports meeting 开运动会have a party 举行一个晚会have sports 进行体育活动have a look 看一看have to 不得不(3)for后加表示时间的名词，译为“之久”表示一段时间。如：We have a talk for ten minutes我们谈了十分钟。相似词辨析1名词作定语即前一名词对后一名词起限制、修饰的作用。如：boy student

15、 男学生 woman doctor 女医生film star 电影明星 credit card 信用卡music teacher 音乐教师 bus stop 公共汽车站注意：(1)当一个名词作定语修饰另一名词时，比如在复合名词中，前一个名词一般应用单数形式。如：a bus stop 公共汽车站apple trees 苹果树the grievance committee 申诉委员会但用复数形式的情况也不少，须个别记忆。如：a glasses frame 眼镜框sports equipment 运动器材an appointments committee 任命委员会(2)用作定语的名词如指人，一般亦

16、用单数形式。如：a boy student 男生girl friends 女友但woman和man用作修饰复数名词的定语时，则一般须用复数形式。如：men doctors 男医生women teachers 女教师(3)复合名词的重音一般在第一个词上，如：a blackbird 黑鹂(以别于a black bird 黑色的鸟)the White House 白宫(以别于the white house 白色的房子)(an English teacher“英语教师”与an English，teacher“英国教师”的区别与此类似)2at school和in a schoolat school和in

17、 a school 都可译为“在学校”，但at school常表示抽象意义，译为“上学”，“求学”，in a school 表示场所，译为“在学校”。如：My son is at school我儿子在学校学习。Tom works in a school，near here汤姆在离这儿不远的一所学校里工作。3class的语义有许多(1)“班级”。如：Are you in Class One？你在一班吗？(2)“课”。如：They have four classes in the afternoon午后他们有四节课。(3)“同学们”。如：Good morning，class同学们，早上好。 (4)

18、“教室”。如：He sits in the middle of the class他坐在教室的中间。中考考点例1 What _ do you like best？FootballAfood Bsubject Csport Dmusic精析 由回答得知，football是一种体育项目，故提问时应用What sport。其他选项均不符合题意。答案 C例2 Mrs Liu teaches _ EnglishWe like _ class very muchAme；his Bme；herCus；his Dus；her精析 us是we的客格人称代词，因后句有we，故选us以作对应。同样class前需要一

19、个形容词性物主代词修饰，故选her与Mrs Liu相应。答案 D例3 _？Its Monday！AWhats the time BWhat day is it todayCIs it Monday DWhats the date精析 根据答语可以推断出此句是用来问“星期几”的。问“星期几”的表达方式就是：What day is it today？答案 B例4 _？Its seven thirtyAWhen BWhat time do you go to schoolCWhats the time DHow did is he精析 根据答语可以推断出此句是用来问时间的。答案 C【跟踪训练】一、选

35、显示出)six days of the weekWhich day is missing？参考答案【跟踪训练】、1B 一般现在时表示经常性动作。本句句意为“330上课。”主语为第三人称单数，故选B。2A be at school 在上学，go to school 上学，本句主语是复数，故选are。3B 英语中每星期以Sunday为第一天。4D 前一句问“你为什么不喜欢数学？”故下一句应给出不喜欢的原因，A、B、C三项皆是近于喜欢的形容词。5A 复合名词的复数形式，只需后一名词变为复数，有man，woman修饰的名词除外。6D 句意为“12月份是一年中第几个月份。”故用序数词，据常识Decemb

36、er是12月，一年中第12个月份。7B 将各疑问词置于题空中，问句中少主语，惟有B项可使句意通顺。8A 课程名称前不加冠词。9C 表示时间日期时若具体到某一天，则用介词on。10A 本题考查连词的使用。句意为：我喜欢音乐因为它使人轻松。故选A。but有转折意味，而or是选择连词均不符合题意，用why句意不通。二、1favorite 2breakfast 3computer 4Swimming 5subject 注意用subject的复数形式。 6teacher 7Wednesday 8interesting 9Chinese 10Biology三、 Thursday October 12thT

38、运动。we是第一人称，所以A不能选，C和D不能直接作谓语。5C some of us 我们中的一些人。A用于否定句，B、D与have的第三人称搭配，D无此结构。6A a singing classlesson 唱歌课，a用在辅音音素为首的单词前。7D a drawing classlesson 绘画课，名词作定语。8C practise doing sth练习做某事。9C would like 后加to do sth为固定结构。10B with表示“和”、“与”之意。五、A 1T 2F 3F 4T 5TB 1C 见文中第一段最后一句。2D 从文中第二段可知。3B 见第三段。4D 见第五段。5A 见最后一段。六、My favorite sport is footballRonaldo is my favorite football playerI am also good at basketballI am on our school basketball teamAfter school I play with my friends【思维拓展训练】1Sunday 2Friday 3Thursday 4Wednesday 5Saturday 6MondayThe day missing is Tuesday
