单选题
1.选C
2.选A；“at the age of+年龄”表示“在几岁时”,是一个固定结构.
3.选C；“I（dont't）think + that从句”固定结构,I 是第一人称单数,所以用dont't,题中只有C选项正确.
4.选A；“know about”意为“知道；了解”；整句意思是“我的外祖父对京剧有些了解”.
填空题
1.does；want ；“for dessert”意为“下午茶时间；甜点时间”；dessert是“甜点”的意思.整句意思是“你的阿姨下午茶想吃点什么?”
2.describable ；describle的形容词形式,意为“可描述的；可记叙的”.
3.successful ；成功的,形容词.
