1.Mike will be a singer in the future,that's what we think.
2.Lisa hurt her leg,so she doesn't have to go to the museum with us.
4.The girls sing English songs was heard by me.
1.It is thought that Mike may be a singer in the future by all of us. (估计考点在于主动语态与被动语态的互换同时考察主语从句）
2. Lisa needn't go to the museum with us because she hurt her leg.(情态动词need的用法）
3.It is said that Yuan longping is one of the ridest people in China.(主动和被动 主语从句的用法）
4.The English songs which are sung by the girl are often heard by me.(这个句子弄的有点复杂，希望其他高手给个简单点的。）
