At night是狀語,
the moon 是主語
is是系動詞
high in the sky是表語
looking like a light是現(xiàn)在分詞短語 作伴隨狀語.
不是因為 你說的原因 因為這是簡單句 如果用 It looks like a light.前面必須是句號 或者 加and
At night,the moon is high in the sky looking like a light.
=At night,the moon is high in the sky and looks like a light.
=At night,the moon is high in the sky .it looks like a light.
另外 look這里 是系動詞 是沒有被動語態(tài)的
