With so many interests and values, they good friends quickly.where改为when分析句子结构可知，这里用when引导定语从句修饰先行词day，且when在定语从句中作时间状语。or改为and我感到伤
75、心，而且不愿意跟姐姐分开。此处表顺承，而不是表选择，故用and。permanently改为permanent此处从句为主系表结构，应该用形容词permanent“永久的”作表语。her改为herself这里用反身代词herself，与从句的主语she呼应。删除find后的outfind out意为“查明，弄清(情况)”，find则指找到或发现寻找的物品。根据语境可知，此处用find。rooms改为room她决定找一间属于自己的公寓，至少有一间自己的房间。此处显然用room的单数形式。to改为for此处表示登广告找室友，应该用介词for表示“为得到，为获取”。在perfect前加amatch在此
76、处是可数名词，表示“匹配”，且常用单数形式，故应在perfect前加不定冠词，又因perfect的发音以辅音音素开头，故用a。sharing改为shared此处非谓语动词作前置定语，表示“共同的”，share与被修饰词是逻辑上的动宾关系，应该用过去分词作定语。become改为became全文记叙的是发生在过去的事情，因此此处应用一般过去时。第二节书面表达【参考范文】Dear Geroge，Knowing that youre interested in what our Chinese family gatherings are like, Im glad to introduce some
77、of my experience to you.We Chinese like to get together with our family very much, especially on important days such as festivals and birthdays. Eating is one of the most necessary parts of the gathering, which is usually prepared by family members together. Not only is the various food delicious but the time we spend making and enjoying it together is enjoyable. Adults chatting and children playing around, this is the typical scene of a happy family gathering.Hope one day you can come and experience by yourself!Yours，Li Hua
