----- Have you heard of Earth Day ?
----Yes . The first Earth Day ______ in 1970 to educate us to protect our planet .| A．celebrates | B．celebrated | C．is celebrated | D．was celebrated |
|
答案
| D |
解析
试题分析：根据语境可知此句的含义是第一个地球日是在1970年举行的。考查的是被动语态的基本构成，因描述的是过去时故用一般过去时的被动语态，其基本构成就是was或were+动词的过去分词，主语是单数故用was，而celebrate的过去分词是celebrated故选D。
点评：被动语态表示主语是动作的承受者。被动语态是动词的一种特殊形式，一般说来，只有需要动作对象的及物动词才有被动语态。汉语往往用“被”、“受”、“给”等词来表示被动意义。被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只改变be的形式，过去分词部分不变。疑问式和否定式的变化也如此 |
