心香半瓣：请star-light及其他大师帮忙翻译４个短语：

１：幕然回首
２：怦然心动
３：小肚鸡肠
４：成全（in 我终于决定＂成全＂你做。。。）

一次问的太多，不好意思。这是几天积累的问题，还有几处没问。以后再问吧。：）
谢谢了！

ANSWER >>>>>>>>>>>>>>>>>>>>>

* 蓦然回首

After searching for him hundreds or thousands of times in the crowd
Suddenly I turned back
Only to find that he was right by a dim light

*怦然心动
