為什麼being是動詞，done是形容詞

done 不是形容詞，是過去分詞beingdone為現在分詞被動語態。

done是do的過去分詞形式，being done是do的進行時被動態

1，現在進行時態的被動語態is/are being done:

A new bridge is being built over the Qiantang River at the moment.錢塘江上正在修建一座新橋。

The cliffs are being constantly eroded by heavy seas.峭壁不斷被洶湧的海水侵蝕。

A hotel room is being prepared for them.

正在為他們準備酒宴

表示動作正在發生，同時動作是被動的，就要用現在進行時態的被動形式。

2，過去進行時態的被動語態was/were being done

I got the feeling I was being watched.

我感覺受到了監視。

The cars were being sold at an average price of $11000.這些汽車以平均11000美元的價格銷售

1. being為助動詞時的用法

當being為助動詞時，用作謂語動詞動詞的being主要與過去分詞連用，構成被動語態。

如：

I'm always being criticized. 我總是挨批。

He is being interviewed now. 他現在正在接受面試。

He is being met at the station tonight. 今晚有人去車站迎接他。

2. being為連繫動詞時的用法

當being為連繫動詞時，用作謂語動詞動詞的being主要與形容詞連用，表示臨時特徵或暫時現象。如：

You’re being stupid. 你真傻。

You are not being very polite. 你可是不大客氣呀。

Your brother is being very annoying this evening. 你兄弟今晚很煩人。
