).
A.closeB.closingC.to closeD.closed
2.--What shall I pay attention to when I make a speech?
--First of all,you should make yourself(
).
A.hearB.hearingC.heardD.to hear
答案上说第一题选D，第二题选C
我觉得这两题有很多相似之处，请高手点拨一下，讲一下理由
这两道题的确相似。从句子结构和成份的角度讲，keep their eyes CLOSED和 make yourself HEARD两个题考察的都是动词的过去分词作宾语补足语。keep后接一个名词或代词作宾语，其后还可接形容词(keep your room CLEAN)、副词(keep the dog OUT)、介词短语(keep the meat IN the fridge)、动词现在分词(keep sb waiting)、过去分词(keep the door closed)作宾语补足语，来补充说明宾语的状态和谓语动词对宾语的影响。类似地，make可接名词(make sb CHAIRMAN)、形容词、副词、介词短语、动词现在分词、过去分词、动词原形[实
