题目内容
7．I am making some signs to put up around the school．（改为否定句）Iam not making some signs to put up around the school．
分析 --我正在做一些招牌来张贴在学校附近．
--我没正在做一些招牌来张贴在学校附近．
解答 答案：am not making．考查否定句．本句含有be动词am，变否定句直接在后面加not．am making现在进行时态的结构，making不变．答案是am not making．
点评 考查否定句．通常是在be动词，情态动词后加not．一般现在时态，主语不是第三人称单数用don't，主语是第三人称单数用doesn't．一般过去时态用didn't．还有其它用法需要牢记．
