27．-I can't believe it． Tom failed the test again!
-He would not be so upset now your advice．
A．would he follow B．should he follow
C．did he follow D．had he followed
【答案】D
【解析】考查虚拟语气。句意：我真不敢相信，汤姆又考砸了！如果他听从你的建议，他就不会那么难过了。分析句子可知，本句是对过去时间的虚拟，if引导的条件句用过去完成时，if省略had提前，句子倒装，所以是had he followed。故D选项正确。
28．_____ the two presidents, China and Suriname signed a number of cooperation documents _____ such issues as jointly building the Belt and Road and mutual visa exemptions (免除).
A．To witness; covered B．Witnessing; to cover
C．Being witnessed by; covering D．Witnessed by; covering
【答案】D
【解析】考查非谓语动词。句意：在两个总统的见证下，中国和苏里南签订了很多合作文件，包括共同构建一带一路和免除双方之间的签证等问题。分析句子可知，第一空是非谓语动词作状语，逻辑主语China and Suriname和witness之间是被动关系，应用过去分词作状语；第二空是非谓语动词作定语，cover和逻辑主语documents之间是主动关系，应用现在分词作定语；虽然C选项中的being witnessed也表被动，但该句不表动作正在进行，故排除。综上所述，故选D项。
