I'm speechless to know that so many people are behind me.

参考译文 知道这么多人在背后支持我，（感激之情）实在是难以言表。

难点突破 本句的难点在于对behind一词的理解。此处behind是介词，意为“支持；赞成”。speechless指“（因惊讶或愤怒等）说不出话的”，如：She was speechless with rage. 她气得说不出话来。

考点归纳 与behind相关的口语表达还有：

fall behind意为“落后，落后于”，如：

Campaigners have warned that the British government is not doing enough to prevent left-handed pupils from falling behind their peers. 活动人士警告说，英国政府在防止左撇子学生落后于同龄人方面做得不够。

behind sb.'s back意为“背地里，私下”，如：

Have you been talking about me behind my back ? 你们是不是在背后说我的闲话？
