Are you going to the school party?這句話的肯定回答應(yīng)該用：Yes,I am.
be going to do 因為有助動詞be,所以回的也用be的相應(yīng)形式
遇到這種問題可以搜索 be going to 的用法,你就會查出你要的答案的,下面是我?guī)湍悴榈降?br/>三、含be going to 的句子變否定句和一般疑問句的變法
由于句子中有助動詞be,因此be going to 的否定句和一般疑問句的構(gòu)成很容易,即在be (am,is,are) 的后面加上not 就構(gòu)成了否定句；把be (am,is,are) 放到句首,在句末加問號就構(gòu)成了一般疑問句,其答語為：Yes,主語+ am/is/are./ No,主語+ isn't/aren't./ No,I'm not.不過 I am...在改為一般疑問句時常常改為“Are you .”.例如：
They are going to see the car factory next week.(肯定句)
They are not going to see the car factory next week.(否定句)
—Are they going to see the car factory next week?
—Yes,they are.(No,they aren't.) (一般疑問句及其回答)
