知识点：动词begin（开始）、cease（停止）、start（开始）、continue（继续）后面既可以跟不定式，也可以接动名词，在意思上没有什么区别：
Even though it was raining, they continued to play / playing football.
尽管下雨了，他们依然在踢足球。
The students ceased to leam / learning French last semester.
上个学期，学生们就停止学习法语了。
注意：在使用以上四个动词时，如果句子为进行时态，一般不用动名词形式，以避免重复。
例；I am continuing learning New Concept English.
没有语法镨误，但显得累赘，
建议改为：I am continuing to learn New Concept English.
我在继续学习《新概念英语》。
As we had had a long walk through one of the markets of old Delhi, we stopped at a square to have a rest. After a time, we noticed a snake charmer with two large baskets at the other side of the square, so we went to have a look at him. As soon as he saw us, he picked up a long pipe which was covered with coins and opened oneof the baskets. When he began to play a tune, wehad our first glimpse of the snake. It rose out of the basketand began to follow the movements of the pipe. We were very much surprised when the snake charmer suddenly began to play jazz and modern pop songs. The snake, however, continued to "dance" slowly. It obviouslycould not tell the difference between Indian music and jazz!
