It takes sb. some time to do sth. It’s very nice of you to offer me a seat. It’s very dangerous for children to cross the busy street. It was great fun to have a picnic there.

A. to keep B. keep C. keeping D. kept A 考点二：作宾语。 1、动词+不定式。 He managed to escape from the fire. 2、动词+特殊疑问词+不定式，“特殊疑问同+不定式”相当于名同，作宾语。 I don't know what to do.
