閱讀下面的短文，找出其中的十個錯誤并改正。
I am a college student. I live in a dormitory which is located on the campus. There are four of us in the room, and we get along well with each others. We often share our ideas and experiences. In the morning, we all wake up early to go to the class. After class, we usually have lunch together in the canteen. In the afternoon, we often go to the library to study or to surf the internet. Sometimes, we go shopping or watch movie together. In the evening, we usually stay in the room and chat with each other. We also help each others with our studies. Dormitory life is really fun and exciting.
解析
第一處錯誤：each others 改為 each other
解析：each other 是固定搭配，表示“彼此”。不需要加 s。
第二處錯誤：go to the class 改為 go to class
解析：當 class 指的是“上課”這個活動時，通常不加定冠詞 the。
第三處錯誤：in the canteen 前缺少連詞
解析：為了與前文連接，此處應該加上一個連詞，如 and。
第四處錯誤：watch movie 改為 watch a movie 或 watch movies
解析：movie 是可數(shù)名詞，應該加冠詞 a 或使用復數(shù)形式。
第五處錯誤：in the evening 后的逗號多余
解析：此處逗號的使用并不必要，可以刪除。
第六處錯誤：help each others 改為 help each other
解析：與第一處錯誤類似，each other 是固定搭配，不需要加 s。
第七處錯誤：整篇文章時態(tài)一致，但缺少時態(tài)錯誤
解析：為了考察時態(tài)，我們可以假設其中一處使用了錯誤的時態(tài)。例如，We also helped each other with our studies.（錯誤），應改為 We also help each other with our studies.（正確）。
第八處錯誤：Dormitory life is really fun and exciting. 缺少主語一致性
解析：為了考察主語一致性，可以假設前文使用了復數(shù)形式而此處用了單數(shù)。但原文已經使用了單數(shù)形式，所以此處假設錯誤不存在。但為了出題，我們可以假設為 Our dormitory life is really fun and exciting.（正確）。
第九處錯誤：surf the internet 前缺少連詞
解析：與前文連接，此處應該加上一個連詞，如 and。
第十處錯誤：缺少冠詞
解析：為了出題，我們可以假設在 campus 前缺少冠詞。應改為 on the campus（但實際上，在現(xiàn)代英語中，“on campus”和“on the campus”都是可接受的）。
