(单选题)

good knowledge of first aid will keep us safe and help save other’s lives in an emergency, so never stop when possible.

A.The, to learn

B.A, to learn

C.A, learning

D.The, learning

参考答案：C

参考解析：

考查冠词和非谓语动词。句意：好好掌握急救知识将保证我们的安全，并有助于拯救他人的生命，所以如果可能的话，永远不要停止学习。前一空考查冠词，knowledge本身是不可数名词，当后面接有具体内容时，前面需要加不定冠词a，构成a knowledge of的结构，意为“掌握”；第二空考查的是非谓语动词做宾语，stop doing意为“不要停止做某事”，综合选项可知，C项正确。故选C。
