求助各位大佬，上一次口语三个fair得了23分，看了一下诊断基本上就是小错误+词汇limit+没有fully developed。应该怎么有针对的提高呢？
Speaking  Skills         Level          Your Performance  
Speaking about familiar topics        Fair(2.5 - 3.0)         Your responses indicate you are able to speak in English about your personal experiences and opinions in a mostly clear and coherent manner. Your speech is mostly clear with only occasional errors. Grammar and vocabulary are somewhat limited and include some errors. At times, the limitations prevent you from elaborating fully on your ideas, but they do not seriously interfere with overall communication.
 
Speaking about campus situations        Fair(2.5 - 3.0)         Your responses demonstrate an ability to speak in English about reading material and experiences typically encountered by university students. You are able to convey relevant information about conversations, newspaper articles, and campus bulletins; however, some details are missing or inaccurate. Limitations of grammar, vocabulary, and pronunciation at times cause difficulty for the listener. However, they do not seriously interfere with overall communication.
 
Speaking about academic course content        Fair(2.5 - 3.0)         Your responses demonstrate that you are able to speak in English about academic reading and lecture material, with only minor communication problems. For the most part, your speech is clear and easy to understand. However, some problems with pronunciation and intonation may occasionally cause difficulty for the listener. Your use of grammar and vocabulary is adequate to talk about the topics, but some ideas are not fully developed or are inaccurate.

其实错误的话都知道在哪，但要通过练习提高难度都不小
语法的话，常见错误就是名词单复数/冠词，主谓一致，第三人称，句子成分不完整
词汇呢，自己注意平时多积累常用词的替换，尤其是3~6题复述的时候，不要完全copy听力里的表达
至于信息点有没有的问题，就不清楚你当时怎么回答的了
