Change是部分的改变,如人和物的改变,最普通的词.例如：这个人长变了,城市变样了等.
Transform是完全改变（通常结果是变好）,例如：普京完全改变了俄罗斯经济.
Exchange是交流交换,和改变的意思相差甚远.如文化交流（Cultural Exchange）,汇率 .
短语：transform from 指由什么变来的
transform into 指变成
change into 变成 change for 替代
在句子中可以看出,“我正在使车库变成变成康乐室.

虚拟语气,关于虚拟语气的省略,你只需记住：
若从句中有were、had或should,即可省略if,并将这三个词置于句首,构成半倒装.
