英语中,谓语用动词的某种固定搭配时的句子成分?
如果使用类似be willing to,be to do,be going to 之类的固定搭配组句,宾语是哪一部分.比如说：a great many people are often willing to sacrifice higher pay for ``````这句中,哪个是谓语,是are?还是are often willing to 都是谓语?宾语应该是哪部分?您能帮我完整的分析一下下面句子的成分吗?Don't worry,I am about to make a close examination on you.请详细一点,我语法实在不济.我自己分析的快疯了,呵呵
