2018 年高考考试英语浙江卷的语法填空题有如此一句：
If you are not going to suffer this problem, then I suggest that the next time you go to your mum’s home for dinner, get a few cooking tips from her. Cooking food can be fun. You might also begin to notice the effects not only on your health but in your pocket.
我不知道为何不需要 on your pocket，这里应该是 the effects not only on...but on...的结构吧？
but in your pocket.
学习英语不可以机械，要灵活。自己做饭不但有益于健康，还省钱。effect on your health and on your money. 但不可以说on your pocket.
