套句展示：

It is necessary that effective actions be taken to prevent this problem.

省略，在语言中，尤其在对话中是一种常见的现象，它可以使语气明了。英语里被省略部分一般可以在句子中补上。本句是省略should的虚拟语气，完整句为It is necessary that effective actions should be taken to prevent this problem. 这种对虚拟语气的省略在四级作文句子里面广为存在，

又如：It is hoped that great efforts should be directed to (expended on / focused on) finding (developing / improving)…中的should也可省略。

必考句型：

(1) Although many have tried, few have succeeded in attempts to .

【分析】本句中tried后的宾语可根据后半句的语义推测得知，所以可以省略，避免重复。

Although many have tried, few have succeeded in attempts to find perfect solutions.

(2) , be it , will bring a lot of happiness into our lives.

【分析】本句是一个超难句型，中间一节省略了whether和might，并进行了倒装，将“be it”恢复后应为whether it might be。Be it…，可译为“比方说”，用来给出更多细节。

The application of electric power, be it to light our rooms or to listen to music, will bring a lot of happiness to our lives.

(3) Christie stared angrily at her boss and turned away, as though to go out of the office.

【分析】as though引导方式状语从句，谓语常用虚拟语气，本句中主句的主语与从句的主语相同，故从句中的主语和谓语省略，即省略了she wanted;如果补全，即为：as though she wanted to go out of the office.
