求分析句子结构 It's about a 40-minute walk from here.
答
about a 40-minute walk from here表语（说笼统点）
it主语，is是谓语， a 40-minute 定语修饰walk, from here介词短语做定语修饰walk
答
it做形式主语，is做谓语，about做副词，40-minute walk做实际主语，from here做补语
答
【It 主语】【 is谓语】【 about a 40-minute walk from here表语】.
【a 40-minute 定语,修饰后面主体名词】walk【 from here 介词短语,定语,修饰前面名词】
