职称英语常用语法详解10

3） 双宾语（直接宾语和间接宾语）结构和复合宾语（宾语 + 宾语补足语）结构：比较下面两个句子：

　　My mother made me a cake.（母亲给我做了块蛋糕。）

　　My father made me a doctor. （父亲把我培养成一名医生。）

　　第*句是双宾语结构，即 My mother made a cake for me.

　　第二句是复合宾语结构，其句能为：My father made me （to） be a doctor （I am a doctor）. 说明复合宾语结构中，宾语和宾语补足语之间有"主谓关系".

　　4） 情态动词：must, should, ought to, can, may, need, used to 等动词称为情态动词，有三大特征：A. 不受主语人称和数的影响，如：He may go now. / May I go now? 句中may的形式不变；B. 否定时在后面加not, 如：You ought not to have cheated her. C. 与另一动词连用，中间不用 + " to ", 如上举例。

　　请根据上述原则，（从语法角度）说出以下那种表达方式是对的：

　　A. She needs to see a doctor.

　　B. She doesn't need to see a doctor.

　　C. Does she need to see a doctor?

　　D. She needs not see a doctor.

　　E. She needn't see a doctor.

　　F. She doesn't need see a doctor.

　　G. She needs see a doctor.

　　从语法角度看，A、B、C、E是对的。

　　5）助动词：帮助实意动词构成某种结构的词，如: He did come yesterday; I saw him in the office.（他昨天确实来了；我在办公室见到他的。—— 表示强调）
