【分析】
连词成句需遵循“找主语→定谓语→连搭配→加标点”的思路：首先从所给单词中找出作主语的人称代词（如we、I、he等）；再确定谓语（be动词、情态动词+实义动词、实义动词的适当形式）；接着结合固定搭配（如be interested in、a lot of等）连接各成分；最后添加标点。
【解析】
1. 先确定主语为We，固定搭配are interested in，后接宾语English，加句号，组成句子：We are interested in English.
2. 主语为I，现在完成时结构为have+动词过去分词（learn的过去分词为learned），固定搭配a lot of后接words，加句号，组成：I have learned a lot of words.
3. 主语为We，情态动词can后接动词原形play，固定搭配in English，加句号，组成：We can play in English.
4. 主语为He，情态动词can连接并列的动词短语play games和do tasks，加句号，组成：He can play games and do tasks.
5. 主语为I，固定结构begin to do sth，此处用过去式began，后接learn English，时间状语three years ago放句末，加句号，组成：I began to learn English three years ago.
【答案】
1. We are interested in English.
2. I have learned a lot of words.
3. We can play in English.
4. He can play games and do tasks.
