请高人指点一下 eat fava beans and discover  与 eating fava的用法

不明白你问什么，尝试一下。

eat and discover  做句子主动词， 表示主语的主要动作。

eating是分词，表示主语的伴随/etc动作。

就是这个地方eat xx and discover xx，为什么用 eating xx会比较好呢？

不好意思，表达不清

eating fava beans triggers hemolytic anemia.

表因果或者先后关系吧.

那 eat and discover好象也能表示一个动作的连续性吧。

这个题A错是不是因为they的问题会产生歧义，怀疑。
