In conclusion, I think simultaneous bilingualism is an advantage, and it’s very helpful for children’s social interaction and future development. However, sequential bilingualism can also achieve the same results by spending a lot of time to study hard. In addition, I think the use of slang and jokes can also help the sequential bilingualism learn more quickly. So I think that becoming a better speaker is not only conditioned by when the languages are acquired, but the exposure time we have in each of them.
