题目很简单,分析如下：
第一题,这里考的是虚拟预期.it is essencia that ……should be……是一般结构,当然,should 可以省略,因此,答案选择C.
第二题,过去完成时.这里主要考察时态,过去完成时表面在过去一点前已经完成的事情,结合题目意思,显然选择D；
第三题,考察keep的用法,keep sb informed of这里是个比较好的搭配,informed of总体做宾语补足语,其他词都不适合.因此,选择C.
第四题,主要考察语法知识.这是结合了时态和主动与被动的句子.由于前一分句和后一分句说的内容不一样,前面是说technique,而主语却是说的yield,因此,分词首先要考虑前面跟了什么,因此,首先排除D,因为没有这样的用法,如果用D,前面就不应该有technique.其次,就时态来说,用现在完成进行时态比较符合句子意思；最后注意到work out设计出,是个及物动词,因此technique需要用被动,因此答案选择C.
