题目内容

4．_______ from endless homework on weekends，the students now find their own activities，such as attending school literature clubs．（　　）

A．

Having freed

B．

Freeing

C．

To be freed

D．

Freed

分析周末从无休无止的作业中解脱出来，学生们现在可以找到自己的活动了，例如参加学校文学俱乐部．

解答答案：D 题干中有逗号分隔，没有连词，要用非谓语动词；free sb from从某事中解脱出来，free与主语students构成动宾关系，且句意表达的是客观事实，要用过去分词作原因状语．故选D．

点评过去分词是非谓语动词的一种，用法很灵活，分为简单式done（表示与谓语同时或几乎同时发生的动作）；完成式having been done（表示先于谓语的动作）．学习时，要把握其用法特征：表示被动和完成．同时还要注意区分现在分词和不定式．

13．My friend，Peg，and I were seeking evidence that there were people who were treating our soil，our waters，our air with the love and respect they deserved．And we found it．
One day we saw a busload of school children on an outing．The bus had stopped at a hamburger stand where we were having a rest，and half-a-hundred children poured out．Busloads of children，of course，were not new，and I hardly gave them more than a glance until I realized what they were doing．Chatting and laughing，the children were picking up as much waste as they could carry from around the stand and its parking area．They took the waste to their bus，where several bags had been brought out for the waste．
Within five minutes，before our astonished eyes，that parking lot had been picked c lean．Impressed，I walked over to their teacher．"I'm interested，"I began．"In fact，I'm surprised at how those kids worked this place over．Is this some kind of environment protection class？"
"You'd never guess it，"he said，"but we're a history class．"
