Rome wasn't built in a day: If students know 1000 words, they might not be able to say one correct sentence because they didn't study (and memorize) phrases and clauses. But if you know 1 phrase or clause, you can make hundreds of correct sentences and so on. I like golf. Golf is relaxing.I like fishing for salmon và Fishing for salmon is relaxing. They already knew about these vocabularies, but how to put many words together to create a proper sentence. Remember this: “My sentences were similar to sentenses which I knew to be correct”.
