被動語態
The Passive Voice
In this lesson, we'll talk about sentences in passive voice. The structure is simple: be + past participle. The passive voice is used to emphasize the people or the things that are acted upon by some other performer of the verb, rather than emphasizing the performer as we do in active voice. This is shown in the example sentence, "We're going to show you how sleep is tied to your physical and mental health." Here, "is tied" is formed by the "be" verb and the past participle "tied" and is in passive voice.

本課要來介紹由被動語態構成的句子。
被動語態的結構並不複雜： 主詞(V) + Be動詞 + 過去分詞。
要注意被動語態是用來表示對「承受」某動作的人或物的關注，而不是關注「執行」某動作的人或物。

例如本課例句：So today, we're going to show you how sleep is tied to your physical and mental health.. 由 Be動詞 加上 tie的過去分詞「tied」所形成被動語態。
