来源:趣趣ABC少儿英语 时间:2019-05-27 17:04:11

   听力的提高是一个循序渐进、日积月累的过程。在听力训练中,我们应该制定目标,坚持不懈,进行系统的听力训练,夯实语言基本功,掌握良好的听力技巧和语法知识,认真体会,不断实践,这样就一定能提高听力水平。

   一、名词:名词单复数,名词的格式

  (一)名词单复数

  1.一般情况,直接加-s,如:book-books, bag-bags, cat-cats, bed-beds

  2.以s. x. sh. ch结尾,加-es,如:bus-buses, box-boxes, brush-brushes, watch-watches

  3.以“辅音字母+y”结尾,变y为i, 再加-es,如:family-families, strawberry-strawberries

  4.以“f或fe”结尾,变f或fe为v, 再加-es,如:knife-knives

  5.不规则名词复数:

  man-men,woman-women,policeman-policemen,policewoman-policewomen mouse-mice

  child-children, foot-feet, tooth-teeth, fish-fish, people-people, Chinese-Chinese, Japanese-Japanese

  不可数名词的复数就是原型: paper, juice, water, milk, rice, tea

  (二)名词的格

  (1) 有生命的东西的名词所有格:

  a) 单数后加 ’s 如: Lucy’s ruler my father’s shirt

  b) 以s 结尾的复数名词后加 ’如: his friends’ bags

  c) 不以s 结尾的复数后加 ’s children’s shoes

  并列名词中,如果把 ’s加在最后一个名词后,表示共有, 如:

  Tom and Mike’s car 汤姆和迈克共有的小汽车

  要表示所有物不是共有的,应分别在并列名词后加’s

  Tom’s and Mike’s cars 汤姆和麦克各自的小汽车

  (2)表示无生命东西的名词通常用“ of +名词”来表示所有关系:

  如:a picture of the classroom a map of China。

  二、冠词:不定冠词,定冠词种类

  (1)不定冠词:a / an a unit / an uncle

  元音开头的可数名词前用an :

  an egg / an apple / an orange / an eraser / an answer / an ID card / an alarm clock / an actor / an actress / an e-mail / an address / an event / an example / an opera / an houran old man / an interesting book / an exciting sport / an action movie / an art lesson

  (8)在称呼或头衔的名词前:This is Mr Li.

  (9)固定词组中:at noon at night by bus

  三、代词、形容词、副词

  形容词,副词:比较级,最高级

  (一)形容词的比较级

  1.形容词比较级在句子中的运用:两个事物或人的比较用比较级,比较级后面一般带有单词than。比较级前面可以用more, a little来修饰表示程度。than后的人称代词用主格(口语中可用宾格)。

  2.形容词加er的规则

  ⑴ 一般在词尾加er ;

  ⑵ 以字母e 结尾,加r ;

  ⑶ 以一个元音字母和一个辅音字母结尾,应双写末尾的辅音字母,再加er ;

  ⑷ 以“辅音字母+y”结尾,先把y变i,再加er 。

  3.不规则形容词比较级:

  good-better, beautiful-more beautiful

  (二)副词的比较级

  1.形容词与副词的区别(有be用形,有形用be;有动用副,有副用动)

  ⑴在句子中形容词一般处于名词之前或be动词之后

  ⑵副词在句子中最常见的是处于实义动词之后

  2.副词比较级的变化规则基本与形容词比较级相同(不规则变化:well-better, far-farther)

  四、数词:基数词、序数词

  (1)1-20

  one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve,thirteen,fourteen,fifteen, sixteen,seventeen,eighteen,nineteen,twenty

  (3)101—999先说“几百”,再加and,再加末两位数或末位数;

  586→five hundred and eighty-six,803→eight hundred and three

  (4)l,000以上,先从右往左数,每三位数加一个“,”,第一个“,”前为thousand.第二个“,”前为million,第三个“,”前为billion

  6,260,309→six million two hundred and sixty thousand three hundred and nine

  750,000,000,000→seven hundred and fifty billion

  序数词

  (4)从二十一后的“几十几”直至“几百几十几”或“几千几百几十几”只将个位的基数词变为序数词。

  twenty-first,two hundred and forty-fifth

  基数词转为序数词的口诀:

  基变序,有规律,词尾加上-th.

  一,二,三,特殊记,词尾字母t,d,d.

  八去t,九去e, ve要用f替。

  ty将y变成i,th前面有个e.

  若是碰到几十几,前用基来后用序。
