第一段:
complaint 为名词,应换成complain。because she is my former deskmate..... 此句必须要有is ,其他表达正确。
第二段:
1.impudence为名词,用法错误。改为形容词impudent,表示厚颜无耻的,其后应加一单词person。
2. 第三四句可以合并,I hate selfish persons like her.
3. 去掉when,After making mistakes, she is always trying to get out of her responsibility. 后面的句子有点中式英语了,这里我就不一一纠正了。
4. 某一天应该用some day, 这段的大概意思就是:when we were to sleep, she took a bath for forty minutes and then spoke with her boyfriend on the phone, which annoyed me so much. However, she refused to go outside and ignored our feelings.
