2．答案 A 解析 如图，CD
→＝CB →＋BD →＝CB →＋12BA →＝－BC →＋12BA →.
3．答案 C 解析 由正弦定理知BC sin A ＝AB sin C ，即2
sin A ＝
3
sin 60°
， 所以sin A ＝2
2，又由题知，BC 5．答案 B 解析 ∵a ＋λb ＝(1＋λ，2)，c ＝(3,4)，且(a ＋λb )∥c ， ∴1＋λ3＝24，∴λ＝12， 6.【答案】D 【解析】由sin α＝10 10. 故2sin 2α＋sin 2αcos ? ????α－π4＝2sin α()sin α＋cos α2 2 ()sin α＋cos α＝22sin α＝ 255. 7．答案 B 解析 ∵b ＝2，B ＝π6，C ＝π 4. 由正弦定理b sin B ＝c sin C ，得c ＝b sin C sin B ＝2×22 12＝22，A ＝π－(π6＋π4)＝7 12π， ∴sin A ＝sin(π4＋π3)＝sin π4cos π3＋cos π4sin π 3＝6 ＋24 . 则S △ABC ＝12bc ·sin A ＝1 2×2×22×6＋24＝3＋1. 8.【答案】B 【解析】sin x ＋ 3 cos x ＝2? ?? ??12sin x ＋3 2cos x ＝2? ????sin π6sin x ＋cos π6cos x ＝2cos ? ????π6－x ＝65，∴cos ? ?? ??π6－x ＝3 5. 9．答案 C 解析 因为(OB →－OC →)·(OB →＋OC →－2OA →)＝0， 即CB →·(AB →＋AC →)＝0，因为AB →－AC →＝CB →，所以(AB →－AC →)·(AB →＋AC →)＝0， 即|AB →|＝|AC →|，所以△ABC 是等腰三角形，故选C. 10．答案 C 解析 ∵OA →·OB →＝0，∴OA →⊥OB →， 以OA 为x 轴，OB 为y 轴建立直角坐标系(图略)， OA →＝(1,0)，OB →＝(0，3)，OC →＝mOA →＋nOB →＝(m ，3n )． ∵tan 30°＝3n m ＝33，∴m ＝3n ，即m n ＝3，故选C. 11. 【答案】B 【解析】∵1n n a b +=，112a =，∴11 2b =， ∵121n n n b b a += -，∴1 12n n b b +=-，∴111 111 n n b b +-=---， 又∵112b =，∴1121b =--． ∴数列11n b ????-?? 是以﹣2为首项，﹣1为公差的等差数列， ∴ 1 11n n b =---，∴1n n b n =+．则201720172018 b =．故答案为：B 12. 答案 B 解析：依题意得sin α＝1－cos 2α＝25 5， cos(α＋β)＝±1－sin 2(α＋β)＝± 45. 又α，β均为锐角，所以0<α<α＋β<π，cos α>cos(α＋β)． 因为45>55>－45，所以cos(α＋β)＝－45. 于是cos β＝cos[(α＋β)－α]＝cos(α＋β)cos α＋sin(α＋β)sin α＝－45×55＋35×25 5＝2525. 13．【答案】2 【解析】[由二倍角公式得2 2 cos sin 8 8 π π -=cos 4 2 = π 14．答案 10 解析 ∵a ⊥b ，∴a·b ＝0，即x －2＝0， ∴x ＝2，∴a ＝(2,1)，∴a 2＝5，b 2＝5， ∴|a ＋b |＝ (a ＋b )2＝ a 2＋2a· b ＋b 2＝ 5＋5＝10. 15. 答案a n ＝1 n . 【解析】∵a n ＝n －1n a n －1 (n ≥2)，∴a n －1＝n －2n －1a n －2，…，a 2＝ 12a 1. 以上(n －1)个式子相乘得a n ＝a 1·12·2 3·…·n －1n ＝a 1n ＝1n . 当n ＝1时也满足此等式，∴a n ＝1 n . 16. 答案：30＋30 3 解析：在△PAB 中，∠PAB ＝30°，∠APB ＝15°，AB ＝60， sin 15°＝sin(45°－30°)＝sin 45°cos 30°－cos 45°sin 30° ＝22×32－22×12＝6－24.由正弦定理，得PB sin 30°＝AB sin 15° ， 所以PB ＝1 2×606－24 ＝30(6＋2)． 所以建筑物的高度为PBsin 45°＝30(6＋2)×2 2＝(30＋303) m. 17．解：(1)因为a ＝(1,0)，b ＝(2,1)， 所以a ＋3b ＝(7,3)，∴|a ＋3b |＝ 72＋32＝58. …………5分 (2)ka －b ＝(k －2，－1)，a ＋3b ＝(7,3)， …………7分 因为ka －b 与a ＋3b 平行，所以3(k －2)＋7＝0，即k ＝－1 3 . ………… 8分 此时ka －b ＝(k －2，－1)＝? ?? ?? －73，－1，a ＋3b ＝(7,3)， ………… 9分 则a ＋3b ＝－3(ka －b )，即此时向量a ＋3b 与ka －b 方向相反． …………10分 18．解 (1)设等差数列{a n }的公差为d ，则a n ＝a 1＋(n －1)d . 由a 1＝1，a 3＝－3，可得1＋2d ＝－3，解得d ＝－2. 从而a n ＝1＋(n －1)×(－2)＝3－2n . (2)由(1)可知a n ＝3－2n ，所以S n ＝n [1＋(3－2n )]2 ＝2n －n 2 . 由S k ＝－35，可得2k －k 2＝－35，即k 2－2k －35＝0，解得k ＝7或k ＝－5. 又k ∈N *，故k ＝7. 19.解 (1)因为m ＝? ???? 22 ，－22，n ＝(sin x ，cos x )，m ⊥n . 所以m ·n ＝0，即22sin x －2 2cos x ＝0，所以sin x ＝cos x ，所以tan x ＝1. (2)因为|m |＝|n |＝1，所以m ·n ＝cos π3＝12，即22sin x －22cos x ＝12，所以sin ? ?? ? ? x －π4＝12， 因为0 12. 20.(1)证明 由a n ＋2＝2a n ＋1－a n ＋2， 得a n ＋2－a n ＋1＝a n ＋1－a n ＋2， 即b n ＋1＝b n ＋2. 又b 1＝a 2－a 1＝1， 所以{b n }是首项为1，公差为2的等差数列． (2)解 由①得b n ＝1＋2(n －1)＝2n －1， 即a n ＋1－a n ＝2n －1. 于是∑n k ＝1 (a k ＋1－a k )＝∑n k ＝1 (2k －1)， 所以a n ＋1－a 1＝n 2，即a n ＋1＝n 2＋a 1. 又a 1＝1，所以{a n }的通项公式为a n ＝n 2－2n ＋2. 21 解：(1) f(x)＝sin ? ???? x ＋π6＋cosx ＝32sinx ＋12cosx ＋cosx ＝32sinx ＋32cosx ＝3 sin ? ????x ＋π3. 当x ＋π3＝2k π＋π2(k ∈Z)，即x ＝2k π＋π 6(k ∈Z)时，f(x)取得最大值 3. 此时x 的取值集合为{x|x ＝2k π＋π 6，k ∈Z}． (2) 由(1)知，f(x)＝3sin ? ????x ＋π3，又f ? ????α＋π6＝33 5， 所以3sin ? ???? α＋π6＋π3＝3cos α＝335，即cos α＝35. 因为α∈? ???? 0，π2，所以sin α＝45，sin2α＝2sin αcos α＝2×45×35＝2425， cos2α＝2cos 2α－1＝－7 25， 所以f(2α)＝3sin ? ???? 2α＋π3＝32sin2α＋32cos2α＝32×2425－32×725＝243－2150. 22. 解 (1)由a 2－(b －c )2＝(2－3)bc ，得a 2－b 2－c 2＝－3bc ， ∴cos A ＝b 2＋c 2－a 22bc ＝32，又0＜A ＜π，∴A ＝π 6. 由sin A sin B ＝cos 2 C 2，得1 2sin B ＝1＋cos C 2 ，即sin B ＝1＋cos C ， 则cos C ＜0，即C 为钝角，∴B 为锐角，且B ＋C ＝5π 6， 则sin(5π6－C )＝1＋cos C ，化简得cos(C ＋π3)＝－1，解得C ＝2π3，∴B ＝π6. (2)由(1)知，a ＝b ，由余弦定理得AM 2＝b 2＋(a 2)2－2b ·a 2·cos C ＝b 2＋b 24＋b 22 ＝(7)2 ， 解得b ＝2，故S △ABC ＝12ab sin C ＝12×2×2×3 2＝ 3. 2016---2017学年度高一上学期英语期中考试题 说明：本套试卷分第Ⅰ卷和第Ⅱ卷两部分，满分150分。考试时间：90分钟。 第I卷 第一部分阅读理解(共20题；每小题2分，满分40分) A The First Time I Sold A Painting The first time I sold a painting was during an art fair(艺术博览会).
