解析
试题分析:考查分词做定语和主谓一致。本题第一空的名词those与动词invite构成被动关系,故使用过去分词短语在句中做定语修饰those;第二空与句子主语nobody保持一致,使用单数形式。句意:除医生和护士和那些胡教授邀请来的人,没有人没有进入病人的房间。故A正确。 点评:当分词做定语的时候,如果构成分词的动词与名词构成主动关系,就使用现在分词做定语;当二者构成被动关系,使用过去分词做定语。单独的一个分词做定语要放在名词的前面,分词短语做定语要放在分词的后面。在英语中,句子的主语和谓语动词要保持数上的一致关系,叫主谓一致。这种关系通常要遵循下面三条原则:1.语法一致原则。句子的主语是单数形式,谓语动词要用单数形式;主语是复数形式,谓语动词用复数形式2.意义一致原则即谓语动词该用单数还是复数取决于主语所表达的内容在含义是单数意义还是复数意义。3.邻近原则谓语动词该用单数还是复数形式,取决于最邻近它的名词、代词或其它词的数。 |
