小学生必备英语知识——基础篇_sing

一、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、名词的格式

(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

l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

l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

(情态)动词can,must, should 后面直接用动词原形。

eg:

1. i / he / she / they can sing.

2.you should keep quiet in the library.

四种简单时态:

一般现在时:i play football.

一般将来时:be going to…/…will …句型: i am going to go to school.

(打算、将要) it will be windy in beijing.

一般过去时:i bought you a book. we went to the park yesterday.

现在进行时:be+动词ing 句型:i am doing my homework.

特殊问句(问什么,答什么)
