7. Dental caries and gingivitis can be exacerbated not only by the foods patients eat but also by when the patients eat them. (A) not only by the foods patients eat but also by when the patients eat them (B) by not only the foods patients eat but also by when the patients eat them (C) not only by the foods patients eat but also by time when the foods are eaten (D) by not only the foods that are eaten by patients but also by the times the foods are eaten (E) not only by what patients eat but also by when they eat it
选E,不过E中的2个并列成分中what patients eat是当成名词了,而 when they eat it也可以这样当作名词用了吗?
