a和an和the的用法冠词:冠词是虚词,放在名称之前,用来说明名词所指的人或事物。英语中的冠词有以下几个特点:最少;用得多;最容易用错。 一.不定冠词的用法: 1.用于可数名词单数前,表示某一类人或事物。 This is a ruler.He’s a student. 2.指人或事物,但不具体说明何人或何物。 There are seven days in a week.We have three meals a day. 3.表示“一个”,但数的概念没有one强。 There’s a tree on the hill.He has an interesting book. 4.指某类人或事物中的任何一个。 An elephant is bigger than a horse.A car runs faster than a bike. 5.用于某些固定词组中。 a lot of\ a bit\have a rest\have a cold\a kind of\a piece of\have a good time 6.首次提到的人或物。 二.定冠词的用法: 定冠词的用法比较难掌握,下面是根据在名词前什么时候用定冠词编的口诀,可以帮助学生加强记忆: 定冠词真古怪,不知何时才能戴,列举下列各情况,只有此时才能戴。 特指某些人或物: 1)彼此双方都明白Don’t tell him the news.They will meet at the school gate.2)前面提过人或物3)序数词前紧紧挨 4)形容词的最高级5)乐器各种头上戴6)独一无二宇宙间 7)普通组成的专有名词the Great Wall8)特指某(些)人或事物The bike under the tree is mine.9)巧学妙用记得快by the way 三.零冠词即不用冠词的情况: 1.专有名词和不可数名词: China,Class One如特指可与冠词连用。 2.泛指的复数名词前:Books are my best friend. 3.在星期、月份、季节、节日前 4.一日三餐、球类、学科、语言名词前 5.职务、头衔、称呼前:Doctor,I am not feeling well. 6.名词前已有指示代词、物主代词或不定冠词时 7.在某些固定短语中 四.注意:1.某些不可数名词表示泛指时,通常不用冠词:I like music.但当特指或具体化时,这些不可数名词与冠词连用:I like the music of the film. 2.季节特指时,也可用冠词:He was born in the summer of 1982. 3.如果由and连接的两个名词所指的是同一人或物,通常只在第一名词前加冠词,如所指的是两个不同的人或事,通常这两个名词前都需加冠词. 同一人时:He became the teacher and friend of the student.他变成了学生的老师和朋友. She is a dancer and singer.她是一名舞蹈家兼歌唱家. 两个人时:A boy and a girl entered together.一个男孩和一个女孩一起走进来. 4.both…and所连接的两个名词前都要用冠词.Both the boys and the girls did well in their exam. one和ones都用于泛指,ones是one的复数形式,二者都用来避免重复。有时二者前有冠词和形容词。不定冠词a和an表示数量“一”, a/an…one仍表示泛指。One用来代替前面提到的可数名词单数或a/an + adj +可数名词单数,ones用来代替前面提到的可数名词复数。二者前有定冠词the时,均表示泛指,且the one,the ones后面常有定语修饰,他们和前面提到的名词是同类异物的关系。 1.I lost my pen yesterday. I will buy one.(one 代a pen) 2.Your question is a difficult one.(one代question) 3.I do not like green apples. I like red ones.(one 代apples) 4.The film is not so good as the one I saw yesterday.(one 代film,后有从句I saw yesterday修饰) 5.The knife and fork that one closest to your plate one a little bit bigger than the ones beside them.(ones代 pairs of knifes and forks,后有介词短语beside them修饰) 本文来源:https://www.wddqw.com/doc/fa9a93a9d1f34693daef3e72.html
