一般現(xiàn)在時一般疑問句和否定句的變法.doc

.一般現(xiàn)在時一般疑問句和否定句的變法 一、 先將句子分成三類：1）含有am, is, are 的句子。 2）含有行為動詞的句子，（如like，have，play，eat，run，need） 3）含有情態(tài)動詞的句子，如can。 (1) 如果是第一類，即含有am, is, are 的句子。只將把am, is, are 調到句首。I am 和We are 要變成are you，some變成any，my變成your，句末用問號。否定句只在be后加not。如am-am not； is -isnt； are-arent。如： I am a boy. （否定句）- I am not a boy. (變成一般疑問句) -Are you a boy? Yes, I am. No, Im not. She is my mother.( 變成一般疑問句) -Is she your mother? Yes, she is. No, she isnt. This is a book.( 變成一般疑問句) -Is this a book? Yes, it is. No, it isnt. These are strawberries.( 變成一般疑問句) -Are these strawberries? Yes, they are. No, they arent. There is some chicken on the table.( 變成一般疑問句) -Is there any chicken on the table? Yes, there is. No, there isnt. (2)如果是第二類，即含有行為動詞的句子（如like，have，play，eat，run，need等）時，要分兩步看主語。 I / We / You / They 時，要借助于助動詞do的幫助來變成一般疑問句。即句型為： Do + 主語 + 動詞原形 + 其他？否定句只在動詞原形前加dont。 例如： I have some tomatoes in my backpack.(否定句)I dont have any tomatoes in my backpack. ( 變成一般疑問句)-Do you have any tomatoes in your backpack? Yes, I do. No, I dont. We play sports every day.（否定句）-We dont play sports every day. ( 變成一般疑問句)-Do you play sports every day? Yes, we do. No, we dont. He / She / It 時， 要借助于助動詞does的幫助來變成一般疑問句。即句型為： Does + 主語 + 動詞原形 + 其他？否定句只在動詞前加doesnt，然后將單三還原成原形。 She watches TV every evening. (否定句)-She doesnt watch TV every evening. ( 變成一般疑問句)-Does she watch TV every evening? Yes, she does. No, she doesnt. 注意：如果是其他名詞的話，在簡略回答中要用人稱代詞來替代，但替代都在第三人稱中，即 he, she, it, they四個中。如： my mother -she your brother - he a book -it five photos-they this/that-it these/those-they my family name-it Tom-he Mary-she Amys sister -she some friends-they (3) 如果是第三類情態(tài)動詞，如can 時，一般疑問句只將can提到句首，否定句將can 變成cant。同時注意一變二，二變一，三不變，some變any。(情態(tài)動詞不受人稱的限制) I can play basketball. ( 變成一般疑問句)- Can you p
