怎么把英語句子改為否定句,一般疑問句
一、陳述句：是用來陳述一件事情或表示一種看法，可分為肯定句和否定句兩種形式.1、謂語動詞是be動詞，助動詞have,has,will，情態動詞can等時，只要直接在這些詞后面加not就構成否定形式.* has already read this new book.（改為否定句）Lily ______ ______ this new book ________.2、謂語動詞是行為動詞而又沒有助動詞或情態動詞時，必須在謂語動詞前加助動詞，一般現在時加助動詞do ，第三人稱單數加does，一般過去時加did，再和not構成否定結構.必須指出的是：don't,doesn't,didn't后都用動詞原形.eg.1)Jill has lunch at school every day.（改為否定句）Jill _____ _____ lunch at school every day.2)The children had a good time at the party.（改為否定句）The children ______ _____ a good time at the party.3)Rose didn't drink any milk this morning.（改為肯定句）Rose ______ ______ milk this morning.二、疑問句：是用來提出問題的句子.A.一般疑問句：以be動詞，have /has/do等助動詞、can/may等情態動詞開頭，以yes或no來回答的問句.它的基本結構是：Be/Have /Has/Did等助動詞（包括情態動詞）+主語+謂語（包括表語）+┄？回答常用簡略回答.1、謂語動詞是be動詞、助動詞、情態動詞時，只要直接把這些詞置于句首，句末改成問號.*'s something wrong with his bike.（改成疑問句）2、謂語動詞是行為動詞時，必須在句首加上助動詞Do、Does（三單）、Did（過去式）加上這些助動詞后，句子中謂語動詞必須用原形.eg.1)Edison built a science lab himself when he was ten.（改成疑問句）2)Those Japanese like Chinese food.（改成疑問句）注意：在把肯定句改成否定句或一般疑問句的時候，要注意句中是否有already、some、something、somebody等詞，如果有也必須進行改變，already要改成yet,some、something、somebody等分別改成any、anything、anybody等.另外，在改成否定句的時候注意把too改成either,both改成neither,all改成none等.在改成一般疑問句的時候，常常把第一人稱I、we改成第二人稱you.B.特殊疑問句：以疑問代詞或疑問副詞開頭，提出疑問的句子.它的基本結構是：特殊疑問詞+一般疑問句語序.但是如果疑問詞在句子中作主語或作主語的定語，就用特殊疑問詞+陳述句語序.。
