第二题A选项是平行呀，add complementary flavors to many food 和stimulate the release of endorphins in the brain。动作和动作平行。只是因为besides是介词，动词要加ING...个人理解啊

dreamflyhigh

可为什么用的these 不是they呢

dzxu

既然add complementary flavors to many food 和stimulate the release of endorphins in the brain，那应该写成“Besides adding complementary flavors to many foods, stimulating the release of endorphins in the brain ……”啊？


these在此题中确实特殊。应该单独做了主语，按照通常规则是不行的。

dreamflyhigh

哦哦，these 确实特殊。。stimulate在句子中是做谓语动词的，—ing做不了谓语。前面的add同为动词，但为了配合besides的介词用法，因此加了ing

找到一道题。188. (GWD-7-Q33) The health benefits of tea have been the subject of much research; besides possibly preventing or inhibiting some forms of cancer, the brewed leaves of Camellia sinensis may also play a role in reducing the risk of heart disease and stroke。。besides可以引导句子中各种成分间的平行，不一定把它放到句首，就一定是主语与之平行。

嗯。


stimulate在句中是做谓语。我的意思是：如果是平行，为了和前面adding的ving形式保持一直，应该改用stimulating，后面再补齐句子的谓语等成分。为什么不是用的这种形式？


目前答案的这种形式：前面是adding，后面是hot sauces，一个ving，一个名词，好像不平行啊？

见楼上那个prep的句子~

非常棒！！！谢谢！


这个例子很好。有点理解了。再找几句来体会体会。




preventing or inhibiting some forms of cancer, the brewed leaves of Camellia sinensis may also play a role in reducing the risk of heart disease and stroke。
