Simple happiness is filled with my heart. 对吗？是is还是are？

好像反了

应该是

My heart is filled with happiness. 才对

给楼主提供三种说法吧

My heart is filled with simple happiness.

Simple happiness fills my heart.

My heart is full of simple happiness.

My heart is filled with simple happiness.

or:

Simple happiness had filled my heart.

都可以.

不对呀。be filled with不是这样用的。
应该是My heart is filled with simple happiness。
对比句子：The bottle is filled with water。
fill 指“充满”
be filled with 就表示“被……充满”

不懂、。。。
