Li Hua 【亮点点评】
亮点一：文章首先交代了写信的目的，接着介绍了晚会的有关情况，最后表达了期待回复之意。

内容完整，层次分明，语言流畅自然，完全符合邀请信的要求。

亮点二：文章使用了一些较复杂的句式结构，显示出作者较高的写作水平，如①to let you know about an English evening 为不定式结构作目的状语；④given by students from different classes 为过去分词短语作定语，修饰performances；⑦句中it作形式主语，真正的主语是后面的含有条件状语从句的句子that you bring some food with you if you like 等。

亮点三：熟练而准确地使用一些较高级的词汇和句型是本文的又一大亮点，如②invite you to join us，③quite a few，⑤encourage participants to exchange small gifts with each other，⑥as well 等。
