Water________ice by us．
- A.can change into
- B.can be changed
- C.can change
- D.can be changed into
分析：change…into…(把……变成……)是及物性的动词短语，change和into之间的词是宾语，把这宾语作主语的话就要用被动语态。change into…(变成……)，此时是不及物性的动词短语，掌握这两者的区别还是从“内力”和“外力”来看，如：The genie(妖怪)changed into smoke，and disappeared．(自己变，是“内力”)The stone was changed into gold by the genie．(是“外力”)本句中有by us，表示的是动作执行者，所以应该用被动语态。B项是被动语态，但缺了into，所以是错的，该选D．
