句型转换
【小题1】He has to help his parents at home. （改为否定句）
He doesn’t have is good at to help his parents at home.
【小题2】She does well in English. ( 改为同义句)
She How many too young ,to What , do English.
【小题3】She needs two teaspoons of yogurt.（对划线部分提问）
　 　 teaspoons of yogurt does she need?
【小题4】She is too young. She can’t look after herself. (改为简单句)
She is 　 　 　 look after herself.
【小题5】She saw a movie about animals last week. (对划线部分提问)
　 did she 　 last week ?

解析：【小题1】Have to半助动词，其否定形式要借助助动词do的形式。【小题2】do well in =be good at【小题3】可数名词的量要用how many来提问。【小题4】too…to…太…而不能【小题5】询问物时要用what.

就是这个解释
