Modification for an essay http://www.italki.com/notebook/entry/73173.htm I think the biggest problem is "礼物(gift)", It must be "派对"[pai dui] (It comes from the pronunciation of the English word 'party'). Secondly, there are some words "他" should be changed to "她", while "王红" is a girl, However, "他" and "她" pronounce in the same way. Then, "昨天在大学的图书馆，一个男人高费，请他明天晚上一起去吃晚饭。" --- there was something happened , but no results came as a subsequence. Something like "She agreed with..." shall be appended. It could be better "昨天在大学的图书馆，一个男人高费，请她明天晚上一起去吃晚饭，她答应了。", and a much better way to express what has happened is "昨天在大学的图书馆，她已经答应了高费明天一起去吃晚饭。" And the word "同一", which means ‘the same’ in Chinese, shall be changed into “同意”(agree). When it comes to "他没认识的。", I think "他不认识的" is better. "没" is always prefixed for something, such as “没(有)人”(nobody) ,"没(有)问题"(no problems), while "不" is prefixed for verbs,for example,"不去"(don't want to go),"不要"(not willing to take). Either of the two sentences below is OK. 王红的朋友他没一个认识的 / 王红的朋友他都不认识. It's hard to explain what is wrong in "他觉得他自己看得很差", It is more closed to "He thought he had a bad eyesight.". The verb word "看(look)" in "The Passive Voice" shall be "看起来难看(be looked bad)" or "长得难看(have a bad looking)", so the sentence is OK to change to "他觉得自己看起来很差", and a better expression is "他觉得自己长得不好看"。 Finally, the word "除了....以外" in the last sentence means "except". But I can not find something to be compared with "make some new friends". Do you mean "高费 was happy, since he had make some new friends."? then it shall be translated to "生日派对后高费很开心，因为他认识了几个新朋友"。
