+
have
done结构，表示过去本来有能力、有可能、有打算、有选择做某事的，但实际上却没有那样做，通常译为“本来可以”，“本来能够”，根据句意分析，主语energy与谓语动词save构成被动意义，故答案为could

“本可以带”（没有带）；C项，mustn't
have
taken（一般不用这种说法）；D项，needn't

“本不需要带”（带了）。由题中“昨天天气不错”可知，此处应指“我本不需要费力带伞”，只有D项符合题意，故正确答案为D。

答案及解析：B
may/might
have
done
(?http:?/??/?www.21cnjy.com?)可能已经做了某事；should
have
done本应该做某事（实际上未做）；must
have
done一定已经做了某事。根据情境可知，手提包没有被偷，这里只是一个不确定的推测。句意：——我把手提包落在火车上了，但是，幸运的是，有人把它送到了铁路办公室。——能重新找回真是难以置信！我是说，有人可能已经偷走了它。故B正确。

答案及解析：D
句意：——玛丽写完了她的文章吗?——没
(?http:?/??/?www.21cnjy.com?)有，而且它应该在下课前完成。从句子结构看，it与finish之间为被动关系，应该使用被动语态；从句子class
was
over.表示过去的时间看，表示的是过去应该做完。ought
to
have
done
sth.表示"过去应该做完某事，但实际上还未完成"。意思与should
have
done
sth.相同，只是语气更重一些。故选D。

答案及解析：A
句意：法律面前人人平等。没有人能
(?http:?/??/?www.21cnjy.com?)凌驾于法律之上。A.
shall用于第二、第三人称，则含有命令、警告、允诺或威胁的语气。B.
must（必须，一定）用于肯定句。C.
may（可以，能够）表允许时一般不与第三人称连用。D.
need
(表示没有必要或询问是否有必要)
需要；故选A。
19.He

答案及解析：B
句意：如果房产税生效，中国可能会出现房价下跌
(?http:?/??/?www.21cnjy.com?)。根据语境可知，这里表示与将来事实相反的假设，与将来事实相反的虚拟条件句中常常用“should
+do”，并且可以将if省略，should提前到句首；本题从句完整的表达是“If
house
property
tax
should
come
into

答案及解析：B
句意：天气很冷而且地面是湿的，
(?http:?/??/?www.21cnjy.com?)昨晚一定下了雨。根据上文the
ground
is
wet可知“昨晚下了雨”是肯定的，故用must

done。故选D。
