l+like+snowshoeing改为否定句？
原句：l like snowshoeing.（我喜欢雪鞋健行。）
改为否定句：l don't like snowshoeing.（我不喜欢雪鞋健行。）
雪鞋健行(Snowshoeing)是近年来流行的冬季运动，虽然少了滑雪活动在雪上驰骋那份刺激，但却比滑雪容易得多，称得上为老少皆宜的健康运动。
怎样才能穿过厚厚的雪地？踩在雪地，一步一脚印地趟过去吧。雪鞋健行的起源可以追溯到数千年前，这是一种愉快、有效地游览冬季景观的方式。在沿着幽静的小径踏往冰冻湖泊的途中，你可以一边听着雪块滚落的声音，一边欣赏沿途的美景色。
英语中陈述句改为否定句怎么改？
1、句中有be动词(am/is/are/was/were)的，在be动词后加not。
如：I can swim.——I can't swim.
He is a math teacher. → He is not a math teacher.
2、句中有情态动词的(can/should/must/would)，在情态动词后面加not;
如：There will be a new building next year. → There will not be a new building next year. (will not可以缩写为won’t)
3、句中没有be动词和情态动词的，在动词前加don’t或doesn’t
① 句中动词为原形的，加don’t .如： I like apples. I don’t like apples.
②句中动词为三单式的，加doesn’t，并将三单式的动词还原成原形。
如：He likes apples. He doesn’t like apples.
4、肯定句中的some在否定句中应改为any
如：There are some students in the classroom. There are not any students in the classroom.
