解：(1)電動車的月產(chǎn)量y為隨著時(shí)間x的變化而變化，有一個(gè)時(shí)間x就有唯一一個(gè)y與之對應(yīng)，月產(chǎn)量y是時(shí)間x的因變量；(2)6月份產(chǎn)量最高，1月份產(chǎn)量最低；(3)6月份和1月份相差最大，在1月份加緊生產(chǎn)，實(shí)現(xiàn)產(chǎn)量的增值．方法總結(jié)：觀察因變量隨自變量變化而變化的趨勢，實(shí)質(zhì)是觀察自變量增大時(shí)，因變量是隨之增大還是減?。?、板書設(shè)計(jì)1．常量與變量：在一個(gè)變化過程中，數(shù)值發(fā)生變化的量為變量，數(shù)值始終不變的量稱之為常量．2．用表格表示數(shù)量間的關(guān)系：借助表格表示因變量隨自變量的變化而變化的情況．自變量和因變量是用來描述我們所熟悉的變化的事物以及自然界中出現(xiàn)的一些變化現(xiàn)象的兩個(gè)重要的量，對于我們所熟悉的變化，在用了這兩個(gè)量的描述之后更加鮮明．本節(jié)是學(xué)好本章的基礎(chǔ)，教學(xué)中立足于學(xué)生的認(rèn)知基礎(chǔ)，激發(fā)學(xué)生的認(rèn)知沖突，提升學(xué)生的認(rèn)知水平，使學(xué)生在原有的知識基礎(chǔ)上迅速遷移到新知上來

解析：可以根據(jù)線段的定義寫出所有的線段即可得解；也可以先找出端點(diǎn)的個(gè)數(shù)，然后利用公式n（n－1）2進(jìn)行計(jì)算.方法一：圖中線段有：AB、AC、AD、AE、BC、BD、BE、CD、CE、DE；共4＋3＋2＋1＝10條；方法二：共有A、B、C、D、E五個(gè)端點(diǎn)，則線段的條數(shù)為5×（5－1）2＝10條.故選C.方法總結(jié)：找線段時(shí)要按照一定的順序做到不重不漏，若利用公式計(jì)算時(shí)則更加簡便準(zhǔn)確.【類型四】 線段、射線和直線的應(yīng)用由鄭州到北京的某一次往返列車，運(yùn)行途中停靠的車站依次是：鄭州——開封——商丘——菏澤——聊城——任丘——北京，那么要為這次列車制作的火車票有（）A.6種 B.12種C.21種 D.42種解析：從鄭州出發(fā)要經(jīng)過6個(gè)車站，所以要制作6種車票；從開封出發(fā)要經(jīng)過5個(gè)車站，所以要制作5種車票；從商丘出發(fā)要經(jīng)過4個(gè)車站，所以要制作4種車票；從菏澤出發(fā)要經(jīng)過3個(gè)車站，所以要制作3種車票；從聊城出發(fā)要經(jīng)過2個(gè)車站，所以要制作2種車票；從任丘出發(fā)要經(jīng)過1個(gè)車站，所以要制作1種車票.再考慮是往返列車，起點(diǎn)與終點(diǎn)不同，則車票不同，乘以2即可.即共需制作的車票數(shù)為：2×（6＋5＋4＋3＋2＋1）＝2×21＝42種.故選D.
