【分析】
1. 画线部分表目的,需用疑问词why提问;原句是一般现在时,主语roots为复数,借助助动词do,动词用原形grow,据此填写。
2. 复数句改单数句时,leaves变为the leaf,动词look变为第三人称单数形式looks,small umbrellas变为单数形式a small umbrella,据此改写。
3. 主语the pine cone是单数第三人称,一般现在时的一般疑问句需借助助动词Does,动词用原形look;否定回答用it指代主语,后接doesn't,据此完成。
4. 连词成句时,先确定主语为The morning glory,再用固定搭配looks like连接宾语a purple bell,组成正确句子。

1. 对目的状语提问用why,原句为一般现在时,主语roots是复数,助动词用do,动词用原形grow,故填Why do; grow。

3. 主语the pine cone是单数第三人称,一般疑问句用助动词Does,动词用原形look;否定回答为it doesn't,故填Does; look; it doesn't。
4. 按“主语+谓语+宾语”结构,组成句子The morning glory looks like a purple bell。
