如果你看不清英语的结构，你可以说 "I'm having trouble understanding the structure of the Engpsh sentence/phrase/text." 或者 "I'm having difficulty following the structure of the Engpsh sentence/phrase/text." 这样你就可以表达出你对英语结构的困惑。

例如：

"I'm having trouble understanding the structure of this Engpsh sentence. Could you help me parse it?"
"I'm having difficulty following the structure of this Engpsh phrase. Could you break it down for me?"
"I'm confused about the structure of this Engpsh text. Could you explain it to me in more detail?"

希望这些例句能帮到你。
