_______ special classes we had! We have learned a lot about paper cutting.
解析本题考查感叹句的结构。句意：我们上的课真特别啊！我们学了很多关于剪纸的知识。class是可数名词，意为“课；课程”，感叹名词要用what，先排除C和D；classes是复数形式，其前不必加不定冠词。适合本题的感叹句的结构是“What+adj.+可数名词复数+主语+谓语！”，故答案为A。
The food is very delicious in that restaurant. We could go and _____ it.
本题考查动词的词义理解。四个选项的含义分别是：sell 卖；help 帮助；produce 生产；try 尝试。根据题干中的“那家餐厅的食物很美味”可推断，我们可以去尝一尝，故所缺的词是try。
—Would you like _____ a film with us tonight?
—Sorry,I have to help my mother do housework.
本题考查 Would you like to do sth.? 句式。问句的含义是“你今天晚上想和我们一起去看电影吗？”，would like to do sth. 意为“想要做某事”，故答案为B。
