Many students in our school are either wearing glasses because of their poor eyesight or being overweight due to lack of enough exercise.
这句话中overweight 前的being能否删掉?Many students are being overweight.还是Many students are overweight?
are wearing为进行时态,are是助动词,wearing是现在分词。either...or...并列相等的语法结构,所以or后面也应该是现在分词being overweight,不能省略being, 因为are不是系词。are being overweight 用be的进行时态,暗示这种状态是临时的、可以改变的。如果觉得进行体使用欠妥,则句子二个时态都应该调整,改为:
Many students in our school either wear glasses because of their poor eyesight or are overweight due to lack of enough exercise.
