问题补充：

When I stayed in the countryside, I enjoyed leisurely walk in the fields, and felt warmth of the sun on my face.

A. / ; the

B. a ; a

C. / ; a

D. a ; the

答案：

A. / ; the

B. a ; a

C. / ; a

(答案→)D. a ; the

解析：考查冠词。前文泛指任何一次悠闲地散布，故用不定冠词。下文根据warmth 后的修饰语of the sun on my face.可知是特指阳光照在脸上的温暖，故用定冠词。选D。
