(18分)6.答案:直線y=kx+1x2+y2-2ax+a2-2a-4=0恒有交點(diǎn),必須定點(diǎn)在圓上或圓內(nèi),即:a2+12≤4+2a所以,-1≤a≤3故為:-1≤a≤3.傾斜角為α的直線的參數(shù)方程為x=a+t?cosαy=b+t?sinα(tl經(jīng)過點(diǎn)x=-3-32ty=3+12t(t都在直線l上,所以可設(shè)它們對應(yīng)的參數(shù)為t1和A,B的坐標(biāo)分別為L的參數(shù)方程代入橢圓的方程4x2+y2=16整理得到t1和t2t1t2=11613,由t的幾何意義可知|PA||PB|=|t1||t2|=11613.…(10分)即|PA|?|PB|=11613.8.答案:(1)點(diǎn)E的坐標(biāo)是(1,1,1)(2)F是AD的中點(diǎn)時(shí)滿足EF⊥平面PCB解析:(1)如圖所示,以所在直線分別為x軸建立空間直角坐標(biāo)系,則0,2m).∴cos〈,〉==.解得m=1,∴點(diǎn)E的坐標(biāo)是(1,1,1).(2)∵F∈平面PAD,∴可設(shè)F(x,PCB∴⊥,且⊥即∴∴,∴F點(diǎn)的坐標(biāo)為(1,0,0)即點(diǎn)F是AD的中點(diǎn)時(shí)滿足EF⊥平面PCB.9.答案:因?yàn)楹瘮?shù)y=(12)x10.答案:D分)n=1時(shí),左邊=s1=1,右邊=1×(1+1)(2+1)6=1,所以等式成立.…(8假設(shè)n=k(k∈N*)時(shí)結(jié)論成立,即Sk=k(k+1)(2k+1)6,…(10分)那么,Sk+1=Sk+(k+1)2=k(k+1)(2k+1)6+(k+1)2=k(k+1)(2k+1)+6(k+1)26=(k+1)(k+2)(2k+3)6=(k+1)[(k+1)+1][2(k+1)+1]6即n=k+1立.…(13n∈N*都成立.…(14分)12.答案:f(x)=x+2x≥22當(dāng)且僅當(dāng)x=2遞增∴當(dāng)x=2時(shí)函數(shù)取最小值趨近0f(x)=x+2x(x∈(0,2])的值域是[22,+∞)故為:[22,+∞)13.答案:C15.答案:ABC即sinc|AB|=sinB||AC|,設(shè)t=sinc|AB|=sinB||AC|,代入OP=OA+λ(AB|AB|sinC+AC|AC|sinB)得,OP=OA+λt(AB+AC)①,∵D是BCAP∥AD,∴點(diǎn)P得軌跡是直線AD,△ABC的重心一定屬于集合M,故選A.AF=AB+23BC=(1,-1),∴AE?AF=1×1+(-2)×(-1)=3.故為:318.答案:由于直線的斜率等于1,故1=4-xx-(-2),解得x=1故選Bx0x+y0y=r2的距離為<r.則有d>r,故直線和圓相離.20.答案:解析:A是列舉法,C是描述法,對于B要注意集合的代表元素是y,故與A,C相同,而D表示該集合含有一個(gè)元素,即方程“x=0”.故選D.x2-2x-15<x+13x2-2x-15>0x+13>0解得:-4<x<-3,或5<x<7,則不等式log12(x2-2x-15)>log12(x+13)的解集為x=2x=-2時(shí),函數(shù)的最大值為5.故選B.l1的斜率為l1的方程為y得(k12-1)x2+22k12x+2k12-1=0.①根據(jù)題意得12?1k21-4l1:24.答案:∵|a|=1,|b|=2,且a與b的夾角為π3,∴a?b=|a|?|b|?cosπ3=12=|a|2+4a?b+4|b|2=12+4×1+4|b|2=21∴|a+2b|=21故為:2125.答案:B二.語文題庫1.答案:C解析:A,“從而”是連詞,表示上文是原因、方法等,下文是結(jié)果、目的等。B,啟用,開始使用,多用于事物。起用,重新任用已退職或免職官員;提拔使用。C,始作俑者:俑,古代殉葬用的木制不瘟不火:指表演既不沉悶也不過火,對角色的把握恰如其分。褒義詞?!拔痢敝笐蚯硌莩翋灧ξ?。2.答案:C與世沉浮。涵養(yǎng):修養(yǎng),很有涵養(yǎng);滋潤養(yǎng)育用造林來涵養(yǎng)水源。3.答案:D4.答案:誠實(shí)守信:一諾千金、表里如一、光明磊落、開誠布公、推心置腹自強(qiáng)不息:愚公移山、廢寢忘食、夜以繼日、披星戴月、自力更生(各答出兩個(gè)即可)5.答案:C5月3區(qū)捐款是5月35月35月3日校長7.答案:C8.答案:在人世間,只有精神是不死的,它如同:巍巍的高山,滔滔的大海,灼灼的陽光,皎皎的明月,習(xí)習(xí)的春風(fēng)。解析:借助一連串的形象之物,深刻地揭示了死并不代表毀滅之哲理。句式簡短,皆為偏正式的,讀起來鏗鏘有力。容,‖(遞進(jìn))而且要通過書的內(nèi)容去了解其反映的時(shí)代和社會,‖(假設(shè)條件)否則就不能算讀些文件逐字逐句照抄一通,‖(假設(shè)條件)那就不能解決任何問題,‖(遞進(jìn))更談不上正確地解夭融了一塊在里面似的,‖(因果)這才這般的鮮潤呀。10.答案:下聯(lián)示例:炎黃子孫德才兼?zhèn)湔购陥D橫批示例:振興中華解析:對聯(lián)是2004年備受歡迎的題目。對聯(lián)的種類較多,但不管何類對聯(lián),使用何種形式,卻又必須具備以下特點(diǎn):一要字?jǐn)?shù)相等,斷句一致。除有意空出某字的位置以達(dá)到某種效果外,上下聯(lián)字?jǐn)?shù)必須相同
