1．(2019·苏州模拟)________ the food, the foreign guests did enjoy the dinner for the Spring Festival.
A．Eat up B．Eaten up
C．To eat up D．Having eaten up
解析：选D 句意：把所有的食物都吃掉以后，这些外国的贵宾非常享受中国春节的年夜饭。根据句意可知这些外国贵宾与吃掉美食之间是主动关系，而且动作已经完成，所以选现在分词的完成式。
2．(2019·无锡模拟)A case of suspected food poisoning in New York has led to 6 high school students ________ to hospital.
A．being sent B．sent
C．sending D．to be sent
解析：选A 句意：纽约一起有嫌疑的食物中毒案导致六名高中学生被送进了医院。动词短语lead to 后面应该跟动名词作宾语，且因为学生是被送往医院，所以用动名词的被动式作宾语。
3．(2019·扬州模拟)Once winter became less of a threat to human beings in literature, literary works ________ it became more positive.
A．featuring B．being featured
C．having featured D．featured
解析：选A 句意：一旦冬天在文学中对人类的威胁减少，以冬天为特征的文学作品就变得更加积极。“以冬季为特点的”作定语，修饰literary works，“feature”与“literary works”之间存在主动关系，所以用现在分词作定语。
