你好，你写得不错，不过有几个问题。 1、“我很想了学汉语”；“一位老师很喜欢了我” correct：“想”和“喜欢”是心理动词（mental verbs），this kind of verb can not followed by“了”，even the sentence is in past tense. But if the predicate has complement, you can use 了follow the mental verbs. For example：这个女孩我喜欢了十年。or 我喜欢这个女孩十年了。It means "I liked this girl for ten years." 2、“已经一年级我们学习汉语了” correct: Maybe you want to express that"我们已经学习汉语一年了or我们学习汉语已经一年了。（We have already learnt Chinese for one year ）" "already" is an adverb here, so it need to followed by verb or complement, and"一年"is complement about time so it usually need to follow the verb. 这是两个比较大的问题，希望对你有帮助。
