Or和and的用法

Or和and的用法 一、连词or主要用法分述如下: 1、用在选择疑问句中连结被选择的对象,意为“或者,还是”。例如: Is he a doctor or a teacher? 他是医生还是教师? Did you do your homework or watch TV last night?你昨晚做作业还是看电视了?Are they singing or reading English? 他们是在唱歌还是在读英语? 下列两个疑问句中的并列成份由于使用了不同的连词,因而句式有所不同。试比较: A、Does he like milk and bread? 他喜欢牛奶或者面包吗? B、Does he like milk or bread? 他喜欢牛奶还是面包? 分析:A 句中使用了连词and,是一般疑问句,对其作肯定或否定回答应用:Yes,he does.No,he doesn`t.B句中使用了并列连词or,因而是选择疑问句,对其回答不用“yes”或“no”,而应根据实际情况直接选择回答:He likes milk.或:He likes bread. 2、用于否定句中连结并列成分,表示“和,与”之意。例如: There isn`t any air or water on the moon.月球上既没有空气也没有水。 The baby is too young. He can`t speak or walk.那婴儿太小,他不会说话,也不会走路。 He hasn`t got any brothers or sisters.他没有兄弟和姐妹。 肯定句中并列连词应用and,在把含有and的肯定句改为否定句时,莫忘把连词and改为or。例如: The students sang and danced in the park yesterday. →The students didn`t sing or dance in the park yesterday. 3、用于句型“祈使句+or+陈述句”中,表示在以祈使句为条件下的相反假设,意为“否则,要不然”。例如: Work hard,or you will fall behind.你要努力学习,否则会落后。 Get up early tomorrow,or you will miss the early train.你明天要早点起身,要不然就赶不上早班火车了。 Don`t jump the queue,or other peopoe will not be pleased.别插队,否则别人会不高兴的。 可以把这类句型中的祈使句换为一个条件句(注意改写时应去掉连词or)。例如:Hurry up,or you will be late for the meeting.→If you don`t hurry up,you will be late for the meeting. 4、用于“either…or…”结构中,意为“不是……就是……”,“要么……要么……”。连结的并列成份可在句中作主语、表语、谓语、宾语等。(注意:连结并列成份作主语时,谓语动词通常与or后的部分保持一致。)例如: Either she or I am right.不是她对就是我对。(连接主语) The shoes in the shop were either too big or too small for me. 店里的鞋对我来说不是太大就是太小 He either does his homework or watches TV on Sundays.他星期天要么做作业,要么看电视。( We play either football or basketball in the afternoon.下午我们不是踢足球就是打篮球。 5、用于连结并列成份,表示不确切、模糊的陈述。例如: This story happened five or six years ago. 这个故事发生在四、五年前。

and的用法及含义

and的用法及含义 And是英语中一个普通的连词,然而and并非只作并列连词用,它还具有一些不太常见的表达方式和意义,应根据上下文的特殊环境,作出判断才能准确理解其用法和意思。 1.and作并列连词,译为“和、并且”等,当连接三个以上的并列成分时,它放在最后一个成分之前,其余用逗号分开,例如: He bought a book and a pen.他买了一本书和一支笔。 Solid,liquid and gas are the three states of matter.固态、液态和气态是物质的三种状态。 2.名词+and+名词,若这种结构表示一个概念时,and+名词相当于介词with+名词,译为“附带、兼”的意思,例如: Noodle and egg is a kind of delicious food.(and egg=with egg)鸡蛋面是一种美味食物。 Whose is this watch and chain?(and chain=with chain)这块带表链的手表是谁的? 3.名词复数+and+同一名词的复数,强调连续或众多的含义。例如: There are photos and photos.照片一张接着一张。 They saw film hours and hours last week.上星期他们一小时接一小时地看电影。 4.形容词+and+形容词,这种结构形似并列,实际并非并列结构。例如: This roon is nice and warm(=nicely warm). The coffee is nice and hot(=thoroughly hot). 5.用and连接动词的用法:and+动词作目的状语。动词go(come,stop等)+and+动词,此时,and+动词相当于in order to+动词,例如: ①I'll go and bring back your boots,(go and bring back=go in order to bringback)我去把你的靴子拿来。 ②and+动词,起现在分词的作用,表示方式或伴随情况。例如: He sat and waited.(and waited=waiting)他坐着等。 ③and+同一动词表示动作长时间地“继续”或“重复”,例如:

or的用法

连词or 连词or在初中英语中是个常用,虽然它只有一个词性,但它却有不同的使用情况。现将主要用法分述如下: 一、用在选择疑问句中连结被选择的对象,意为“或者,还是”。例如: Is he a doctor or a teacher? 他是医生还是教师? Did you do your homework or watch TV last night?你昨晚做作业还是看电视了? Are they singing or reading English? 他们是在唱歌还是在读英语? 下列两个疑问句中的并列成份由于使用了不同的连词,因而句式有所不同。试比较: A、Does he like milk or bread? 他喜欢牛奶还是面包吗? B、Does he like milk or bread? 他喜欢牛奶还是面包? 分析:A 句中使用了连词and,是一般疑问句,对其作肯定或否定回答应用:Yes,he does.No,he doesn't.B句中使用了并列连词or,因而是选择疑问句,对其回答不用“yes”或“no”,而应根据实际情况直接选择回答:He likes milk.或:He likes bread. 二、用于否定句中连结并列成分,表示“和,与”之意。例如: There isn't any air or water on the moon.月球上既没有空气也没有水。 The baby is too young. He can't speak or walk.那婴儿太小,他不会说话,也不会走路。 He hasn't got any brothers or sisters.他没有兄弟和姐妹。 肯定句中并列连词应用and,在把含有and的肯定句改为否定句时,莫忘把连词and改为or。例如: The students sang and danced in the park yesterday.→The students didn't sing or dance in the park yesterday. 三、用于句型“祈使句+or+陈述句”中,表示在以祈使句为条件下的相反假设,意为“否则,要不然”。例如: Work hard,or you will fall behind.你要努力学习,否则会落后。 Get up early tomorrow,or you will miss the early train.你明天要早点起身,要不然就赶不上早班火车了。 Don't jump the queue,or other peopoe will not be pleased.别插队,否则别人会不高兴的。可以把这类句型中的祈使句换为一个条件句(注意改写时应去掉连词or)。例如: Hurry up,or you will be late for the meeting.→If you don't hurry up,you will be late for the meeting. 四、用于“either…or…”结构中,意为“不是……就是……”,“要么……要么……”。连结的并列成份可在句中作主语、表语、谓语、宾语等。(注意:连结并列成份作主语时,谓语动词通常与or后的部分保持一致。)例如: Either she or I am right.不是她对就是我对。(连接主语) The shoes in the shop were either too big or too small for me. 店里的鞋对我来说不是太大就是太小(连接表语) He either does his homework or watches TV on Sundays.他星期天要么做作业,要么看电视。(连接谓语) We play either football or basketball in the afternoon.下午我们不是踢足球就是打篮球。(连接宾语) 五、用于连结并列成份,表示不确切、模糊的陈述。例如: This story happened five or six years ago. 这个故事发生在四、五年前。 --Is the street straight? --More or less.
