B 主语 I 与 invite 之间是被动关系，故用被动语态；由 last week 可知“被邀请”发生在过去，需用一般过去时态。因此空格处应用一般过去时的被动语态，构成为：was/were+过去分词。3. D 主语 The first Earth Day 与 celebrate 之间是动宾关系，需用被动语态；由时间状语 in 1970 可知用一般过去时态。因此空格处应用一般过去时的被动语态。故选 D。4. B 由时间状语 in 1989 可知用一般过去时态；happen“发生” ，没有被动语态，用主动表示被动。二、1. was made2. was invented3. was invited4. were produced5. to laugh
