Question

6．我们英语老师善于讲有趣的笑话．（be good at）Our English teacher is good at telling interesting jokes．．

Answer 1

分析 Our English teacher is good at telling interesting jokes．

解答 答案：Our English teacher is good at telling interesting jokes． 说的是客观事实用一般现在时，主语是our English teacher单数，故be good at（表示擅长…）中的be动词选择is，at是介词，后加动名词短语telling interesting jokes做宾语，tell jokes表示讲笑话，故答案是Our English teacher is good at telling interesting jokes．

点评 be good at中的at是介词，后加名词代词或动名词做宾语．
