陈述句用来说明一个事实或表明说话人的看法； 陈述句的末尾用句号，朗读时一般用降调；陈述句分为肯定句和否定句式；陈述句用正常语序。下面我们就来看看陈述句的形式：陈述句的肯定句式：1.主语+系动词+表语He is a teacher.他是一名老师。2.主语+实义动词+其他Lily dances well. 莉莉跳舞跳得很好。3.主语+情态动词+动词原形+其他Mary can speak Japanese.玛丽会说日语。4.主语+助动词+动词原形+其他They will go aboard next year. 他们明年要出国。陈述句的否定句式1.主语+be动词/情态动词+not+其他These are not my pencils.这些不是我的铅笔。She cannot play the piano well. 她钢琴弹得不好。2.主语+do/does/did+not+动词原形+其他。I don’t like singing.我不喜欢唱歌。3.主语+助动词will+动词原形+其他。I won’t go to work tomorrow. 我明天不去上班。由肯定句变否定句的方法1.找原句的动词若动词是am, is, are, can, must, will等，直接在动词后加not做否定。若动词是have, want, like等实义动词，要借助助动词don’t或doesn’t放在原句动词之前变否定句（原句动词为单三形式用doesn’t,其他形式用don’t）.2.原句其他单词位置不变E.g. I am a teacher. ----I am not a teacher.Mary likes apples.------Mary doesn’t like apples.
