2. the, you, water, please, could, plants (?) (连词成句) ______
3. 玛丽,你能帮我洗衣服吗？(汉译英) Mary, ______ ______ ______ ______ do the laundry? 当然,妈妈。今天下午我可以和朋友打网球吗？ ______ ______, Mum. ______ ______ play tennis with my friends this afternoon? 抱歉,你不行。你必须先完成作业。 ______, ______ ______. You must finish your homework first.

2. 连词成句时，先确定疑问词Could，然后是主语you，接着是动词短语water the plants，最后是表示请求的语气词please，所以连成句子“Could you water the plants, please?”。
3. “你能帮我做某事吗”常用“Could you help me do sth.”；“当然”是“Sure/Certainly”；“我可以做某事吗”用“Could I do sth.”；“抱歉，你不行”是“Sorry, you can't”。
1. Sure; you can 2. Could you water the plants, please? 3. could you help me; Sure/Certainly; Could I; Sorry, you can't
