（1）在甘肅省貧困山區中學支教對於你來說可能很無趣.然而，這卻改變了來自北京楊磊的一生.這位北大畢業生首先選擇去那裡作為志願者進行為期一年的計畫.這一項目是由教育部和中國少年先鋒隊啟動的.每年，他們會派100名志願者去山區支教.
對於楊磊來說，山區裏的生活是一段新的歷程.她所在的山村在位於海拔2000米，所以稀薄的空氣使她感覺很難受.那裡的食物很簡單——老師們一天三餐都吃稀飯.幸運的是，楊磊的媽媽贊同她的决定.她說她和她的丈夫認為這是一個好主意.“現在的年輕人需要經歷不同的事情”她說.
大多數學生都住在學校的宿舍.他們讀書都很努力.他們每天在上5點起床，讀書讀到晚上11點.他們很愛那裡的支教老師.“你們和他們沒有什麼不同”楊磊說，“他們說我們就像他們的大哥哥大姐姐一樣，他們覺得很幸運.”
一些學生可能不能上高中或大學，大多都是因為家境貧困，家裡負擔不起學費.“雖然對此我無能為力”楊磊說，“但是我可以幫助我的學生開闊眼界，給予他們一生中的啟明星.”她說她希望能在那些孩子們的一生中起到很好的作用.
楊磊非常喜歡她的志願者生活.當她支教的時間即將結束時，她說在她完成她的學業之後，她還會回到這個地方的.現在，她在甘肅省平凉市的一所中學任教.
（2）代溝已經成為了一個很嚴重的問題.我在報紙上讀到一篇關於代溝的報導.一些孩子在和父母吵完架之後就自殺了.我認為這是因為他們之間沒有建立良好的溝通.父母現在都忙於工作，所以他們沒有足够的時間待在孩子身邊.隨著時間流逝，他們就會覺得他們之間缺少共同話題.我想告訴父母們，你們應多陪陪自己的孩子，去瞭解他們.作為孩子，把你們的思想告訴你們的父母.這樣，你們才能更好的瞭解對方.

張大爺家養的雞的只數是鴨的4倍，已知雞比鴨多48只，那麼雞，鴨各有多少只？

設鴨x只，則雞4x只
4x-x=48
x=16
即：鴨16只，雞4×16=64（只）

已知函數f（x）=ax+3/x-1，若（2,7）是f^-1（x）影像上的點，求，y=f（x）的值域

（2,7）是f^-1（x）即f^-1（2）=7所以f（7）=2所以2=（7a+3）/（7-1）a=9/7f（x）=（9x/7+3）/（x-1）=（9x/7-9/7+30/7）/（x-1）=（9x/7-9/7）/（x-1）+（30/7）/（x-1）=9/7+（30/7）/（x-1）（30/7）/（x-1）≠0所以f（x）≠9/7（-無窮，9/7）∪（9/7，…

某校兩個班級步行去郊外採集生物標本.初一（5）班先出發，速度4km/h.1小時後，初一（6）班出發，速度為6km/h.學校派一名聯絡員騎車與初一（6）班同時出發，速度為12km/h.
請你設計兩個不同的問題，並用方程的有關知識來解决你所提出的問題.

問：6班何時追上五班
答：設用時X小時追上（自己寫詳細一點）
4（X+1）=6X
4X+4=6X
-2X=-4
X=2
同理.解設聯絡員何時追上
4（X+1）=12X
解得X=1

一元一次方程的公式
如果a=b，那麼a±c
如果a=b，那麼ac=
如果a=b（c≠0），那麼a/c=
我是自學教學軟體上沒有這個書上有

如果a=b，那麼ac=（bc）
如果a=b（c≠0），那麼a/c=（b/c）
