《名词复数形式的构成法.docVIP

名词复数形式的构成法： 在词尾加“s”：book-books，map-maps 以“s”“x”“ch”结尾的词加“es”：bus-buses，box-boxes，watch-watches 以辅音加“y”结尾的词，将“y”改为“ies”：city-cities，dictionary-dictionries 以“f”或“fe”结尾的词，将它们改为“ves”：leaf-leaves，wife-wives 以“o”结尾的词，有生命的后面加“es”，没生命的加“s”：hero-heroes，photo-photos 单复数一样：fish-fish，deer-deer，sheep-sheep 没有规则的，必须死记硬背的：man-men，woman-women，child-children，foot-feet，tooth-teeth，mouse-mice I like apples. He likes apple. He watches TV. My mother washes my clothes. 疑问句和否定句的构成: 凡是含有be, can, may, must, shall, will等词的句子, 变为疑问句时, 就是将该此词移至句首, 变为否定句时就是在该词后面加 “not”: You are a student. Are you a student? You are not a student. She can dance. Can she dance? She can not dance. 没有含以上词的句子, 变为疑问句时, 在句首加 “do”(主语如果是第三人称单数则写成 “does”); 变成否定句时,在动词前加 “don’t”(主语如果是第三人称单数则写成 “doesn’t”) You like English. Do you like English? You don’t like English. He likes English. Does he like English? He doesn’t like English. They are farmers. Are they farmers? They aren’t farmers. He buys a car. Does he buy a car. He doesn’ t buy a car. You play football. Do you play football? You don’t play football. He can sing well. Can he sing well? He can’t sing well. 肯定句的主语如果是第一人称, 在疑问句中要改为第二人称. We are students. Are you students? I am a teacher. Are you a teacher? I like my mother. Do you like your mother? 肯定句中的 “some”, 在疑问句和否定句中都要改为 “any” I have some money. Do you have any money. I don’t have any money. There are some books. Are there any books. There aren’t any books. I can see some stars in the sky. We like our school. We go to school every day. He has a new computer. The new bag is mine. 一般现在进行时: “be + 动词ing” 表示该动作此时此刻正在发生,或正在进行. We are learning English in the classroom now. He is playing football on the playground. 表示该动作计划好, 安排好在将来发生(只有少数动词可以这样用) They are coming here tomorrow. I am leaving Xiamen tomorrow. 3.表示该动作在目前这段时间里频频地发生, 而不是每时每刻都在发生. He is reviewing his lessons this week for the tests next week. 将来时: 在动词之前加shall(用于第一人称), 或will(用于其他人称) I shall go to Beijing next week. We shall go to Beijing next
