she was told a piece of exciting news ,and __to tears.

因为是被一则令人兴奋的新闻感动得流泪的,是被感动,所以用被动语态,

and起的作用。

被感动得哭， 是被动， 所以要用was moved

she was told a piece of exciting news ,and was moved to tears.
她获悉了一条令人激动的消息，感动得落泪。

move to tear 指的是流泪,但这里的流泪是因为前面提到的she was told a piece of exciting news引起的,所以是被a piece of exciting news这件事感染而流泪,所以填被动态be done,而且要注意时态是过去时,所以用was,即was moved

was moved 即被感动的，和to tears 连起来是听到这个令人激动的消息，她被感动的落泪了。
