Nice sentence:

1. (雙語者的3個好處）Two-tongued people enjoy a variety of non-linguistic advantages. Most notably, they have shown that bilinguals get dementia on average four years later than monolinguals, and that they have an edge in（有優(yōu)勢） "executive control" - a basket of abilities that aid people doing complex tasks, irrelevant information and updating working memory. As well as that, a second language expands the number of people you can talk to. It adds to the ways you can say things, and so offers a second point of view on the whole business of expression. In addition, bilingualism may help you understand other people. In other word, people who speak two languages are better at grasping other perspectives, perhaps because they are always keeping track of who speaks what, a regular reminder that everyone is different.
2. (為什么雙語能力會產生產生以上好處）Although the philosophy behind the benefits I mentioned before is unclear, there is a hypotheis, go popular, which suggests that having two languages means suppressing one when speaking the other, a kind of constant mental exercise that makes the brain healthier. That is why the ability of speaking two or more languages can delay the onset of dementia.
