Half the American students’ ine is from their parents, thirtyfive percent from from part time jobs, and fifteen from scholarships. Chinese students, on the other hand, get niy percent of their ine from their parents. In my opinion, there are two main reasons for this. One is that Chinese parents care so much for their children that it is almost unthinkable for students to live on their own. The other is that Chinese students have fewer chances to find parttime jobs. 小結(jié)： 1。 說明文 說明文出題形式： 1。圖畫 說明文的篇章結(jié)構(gòu) 主題句 —— 引出全文的話題 支持句 —— 圍繞話題展開討論 ， 用事實(shí) ， 理由 ， 觀點(diǎn)等來進(jìn)行解釋 ，說明或論證 。信息歸類；支撐論點(diǎn)。分析產(chǎn)生這種不同現(xiàn)象的可能原因。 5 語言簡(jiǎn)潔；交際得體。 結(jié)束句 —— 對(duì)話題進(jìn)行概括 ， 總結(jié)歸納 。 （相同；不同） 3。 2。 4 合情合理；邏輯清晰。 說明文的寫作方法： 列舉法 用事例說明主題 可用表示順序的示意詞來突出每個(gè)實(shí)例。上下連貫；邏輯清晰。概括說
