1、谓语动词是be动词，助动词, 情态动词等时，只要直接在这些词后面加not就构成否定形式。eg. Lily has already read this new book. (改为否定句)

Lily ______ ______ this new book ________.

2、谓语动词是行为动词时，必须在谓语动词前加助动词，一般现在时加助动词do ，第三人称单数加does，一般过去时加did，再和not构成否定结构。必须指出的是：don't, doesn't, didn't后都用动词原形。

eg.1)Jill has lunch at school every day. (改为否定句)

Jill _____ _____ lunch at school every day.

2)The children had a good time at the party. (改为否定句)

The children ______ _____ a good time at the party.

三．疑问句：是用来提出问题的句子。

A.一般疑问句：以be动词, 助动词、情态动词开头，以yes或no来回答。

它的基本结构是：

Be/Have /Has/Did等助动词（包括情态动词）＋主语＋谓语（包括表语）＋┄？回答常用简略回答。

1、谓语动词是be动词、助动词、情态动词时，只要直接把这些词置于句首，句末改成问号。eg. There's something wrong with his bike.（改成疑问句）

______ _____ _______ wrong with his bike?

2、谓语动词是行为动词时，必须在句首加上助动词Do、Does（三单）、Did（过去式）加上这些助动词后，句子中谓语动词必须用原形。

eg. 1)Edison built a science lab himself when he was ten. （改成疑问句）

______ Edison ______ a science lab himself when he was ten？

2)Those Japanese like Chinese food.（改成疑问句）

______ those Japanese ________ Chinese food?

注意：在把肯定句改成否定句或一般疑问句的时候,要注意句中是否有already、some、something、somebody 等词，如果有也必须进行改变，already要改成yet，some、something、somebody等分别改成any、anything、anybody等。另外，在改成否定句的时候注意把too改成either, both改成neither, all改成none等.在改成一般疑问句的时候，常常把第一人称I、we改成第二人称you。复合句变一般疑问句通常只变主句，从句不变B.特殊疑问句：以疑问代词或疑问副词开头，提出疑问的句子。

它的基本结构是：特殊疑问词＋一般疑问句语序。但是如果疑问词在句子中作主语或作主语的定语，就用特殊疑问词＋陈述句语序。常用的疑问词有：what, who(whom),

whose,which,when,where,how,why等，回答时针对问句中的代词和副词来回答，不用yes或no 来回答。

1)对指物名词或谓语动词提出疑问，疑问词用what
