Hi Colin . How are you feeling today ?   Oh , I feel ok but I ’ m still very tired .   It's probably jet lag .   I think so . One minute I feel quite awake , and the next I feel very tired .   Do you want to visit any tourist spots in the city ?   Oh yes , I'm very interested in Chinese history so I ’ d like to visit the Summer Palace .   Good idea . I ’ d be very happy to go there .
