There are a lot of things to be done. 有很多事要做。

2. 现在分词的被动语态：由“being+过去分词”构成。如：

The building being repaired is our library. 正在维修的那座楼是我们的图书馆。

3. 动名词的被动语态：由“being+过去分词”构成。如：

She doesn’t like being kept waiting. 她不喜欢人家让她久等。

He was afraid of being laughed at. 他担心备人嘲笑。(from www.zkenglish.com)

【注意】过去分词本身可以表示被动意义，所以没有相应的被动语态形式：

The door remained locked. 门仍然锁着。
