5、，咖啡的和火腿月饼。There are 40 students in the classroom, including me. 班里有40名学生，包括我在内。同样，included也有介词用法，且：including + 宾语 = 宾语 + included。所以上个例句亦可写成：There are 40 students in the classroom, me included.4. succeedsucceed作不及物动词，意为“成功”；表示做某事做成功了，succeed 后通常接in doing sth。例如： His plan succeeded.他的计划成功了。At last he
