Our teacher demanded that all of us English every day．

A. should practise to speak

B. would practise speaking

C. could practise speaking

D. practise speaking

答案：

A. should practise to speak

B. would practise speaking

C. could practise speaking

(答案→)D. practise speaking

解析：考查词组和虚拟语气：句意：我们老师要求我们所有的人每天练习说英语。Practise doing练习做…，排除A，还有这句话的主句谓语是demand，从句的谓语应该是虚拟语气，用should do，should可以省略，选D。
