Suddenly, I hear a high-pitched keening sound: Oh no, oh no. Dad puts down the phone and turns to me, crying.

突然，我听到一尖锐哭: “，不，，不。”爸爸放下电话，哭着转向我。

It landed on its hands and knees and made a high keening noise like a cornered rat.

它用手和膝盖着地， 像一只被逼到老鼠一样发出尖锐哀嚎。

The screaming had a thin sharp unreal sound, something like the screaming of coyotes in the moonlight, but it didn't have the rising keening note of the coyote.

尖叫有一种虚幻尖锐音， 有点像郊狼在月光下尖叫， 但没有郊狼上升哀嚎。
