unit 10if you go to the party, you will have a great time1. if you do,youll have a great time!如果你去参加聚会,你一定会玩儿得很开心的!该句是一个复合句。if you do是if引导的条件状语从句,主句为youll have a great time。do在这里代替上文中提到的动作。在英语中,为了避免重复,常用do/does/did代替上文中的实义动词(短语)。如:ill go to school on foot today.今天我将步行上学。if you do,youll be late for class.如果那样,你将会上课迟到。have a great time=have fun=enjoy oneself意为“玩得高兴,过得愉快”。如:we have a great time at school.=we have fun at school.=we enjoy ourselves at school.我们在学校里玩得很开心。2.half the class wont come班上一半的学生不会来half在本句中作形容词,修饰the class,此时half可以转换成名词的用法,即“half of+名词”。如:half the children are from mountain areas.=half of the children are from mountain areas.有一半的孩子来自山区。he spent half his spare time reading.他有一半的空闲时间都花在阅读上。注意:half the.作主语时,谓语动词的形式由其后的名词决定。如:half the work was done by his father.有一半的活都是他父亲干的。half the students in the class are boys.这个班有一半的学生都是男生。class作为整体名词作主语时,谓语动词用单数;指“全班学生”时,谓语动词用复数。类似的词还有school,team,family,nation等。如:the class are hard-working.这个班的学生很勤奋。his family is a happy one.他的家庭是一个幸福的家庭。3.if we ask people to bring food,theyll just bring potato chips and chocolate because theyll be too lazy to cook.如果我们让人们带食物来,他们将只带炸薯条和巧克力,因为他们太懒而不去做。ask sb.to do sth.“要求某人做某事”;ask sb.not to do sth.“要求某人不要做某事”。如:our teacher asks us to read every day.我们的老师要求我们每天阅读。potato chips“炸土豆片;炸薯条”,其中,名词potato作定语,变复数时只变后面的名词。如:apple treeapple trees苹果树【拓展】表示性别的man或woman作定语修饰名词时,如果变复数则man/woman以及其修饰的名词都要变。如:a man teacher(一位男老师)two men teachers(两位男老师)a woman doctor(一位女医生)some women doctors(一些女医生)4.if i(go) to the party,they(be) upset.如果我去参加聚会,他们将会很难过。upset形容词,意为“通过的;失望的;沮丧的”。如:he will feel upset when he hears the bad news.当他听到这个坏消息时,他将会感到很失望。5.if i(take) a taxi,it(be) too expensive.如果我乘出租车去,它将会太昂贵。take a taxi意为“乘出租车”。如:i sometimes take a taxi to school.我有时乘出租车去上学。【拓展】英语中交通方式的表达方式:take+a/the+交通工具名词。这是一个动词短语,在句中用作谓语。如:i often take a bus to school.我经常乘公共汽车去上学。by+交通工具名词。这是一个介词短语,在句中用作状语。by后的交通工具名词要用单数形式,且交通工具名词前不能有任何修饰词。如:i go to school by bus.我乘公共汽车去上学。用某些动词短语表示,如walk to.“步行去”;drive to.“开车去”;fly to.“乘飞机去;飞往”。对交通方式提问用疑问词how。如:how do you go to school?你怎样去上学?by bus./on foot.乘公共汽车。/步行。6.can you give me some advice please?你能给我一些建议吗?advice不可数名词,意为“劝告;建议”,没有复数形式也不能与不定冠词an连用,表示数量时要借助于piece或用some(一些),much(许多)等词。如:a piece of advice一条建议some pieces of advice许多条建议give sb.some advice给某人提一些建议语法指津if引导的条件状语从句主句从句例句主句是一般将来时从句时态应用一般现在时he will come here on time if it doesnt rain.如果不下雨,他会按时到达这儿。主句是祈使句please stay at home if it rains tomorrow.如果明天下雨,请待在家里。主句的谓语含有can,may,must等情态动词if you like,you can stay here for the weekend.你如果愿意就留在这里过周末。主句的谓语是hope,wish,want等动词i want to go there if the rain stops.如果雨停了,我想去那儿。例1 what should i do if such an unlucky thing_me?a.happens on b.happens to c.will happen to d.is happen on解析:考查时态。if引导的条件状语从句遵循主将
