One possible version:

In my opinion, native language can promote foreign language learning; meanwhile, it also has some negative effects on foreign language learning.

Although different languages have different vocabulary and rules, language has one thing in common: it is the tool that humans use to express thoughts. Therefore, learning the native language well will help better understand a foreign language. Compared with those who are not good at their native languages, a good native language learner has better writing and speaking skills. These skills are also helpful for them to learn a foreign language. However, the native language has some negative effects on foreign language learning. For example, Chinese students often struggle with word order when learning English, even though they know that the two languages are quite different in this aspect.

In a word, people should try to learn their native language well, and, at the same time, avoid its interference in foreign language learning.
