1、考点5:助动词及其他真题再练在下列句中的空白处填入适当的内容(1个单词),并说明理由。(2014卷II68)Then the driver stood up and asked,“_anyone lose a suitcase at the last stop?”考查疑问句的结构,由asked可知直接引语是一般疑问句;由“at the last stop”(在上一个站)可知,谓语动词应用一般过去时,而lose是原形,故应填助动词Did,构成一般过去时的疑问式,注意句首首字母要大写。Did思路点拨1.由单词asked判断,其后的直接引语为疑问句。疑问句的主语前应是情态动词、be动词,或者助动词d
