The crazy cyclist was 40 kilometres into his Sunday ride when he stopped by the side of the road to text his family saying he’d be home in about 30 minutes. Moments later, he was lying in the ditch, unconscious.Larissa Arthur was driving back to Calgary from a hike in Field, BC with a friend. It was a warm and sunny day, and the two were chatting when a flush of yellow caught Arthur’s eye. She immediately pulled off the road.As Arthur approached the figure, she feared the worst: Estepa was covered with ants and exhibited no signs of life. “There was no pulse and he wasn’t breathin g,” says Arthur. A bystander called 911 and Arthur, a registered nurse, started chest compression. She and two other drivers took turns carrying outCPR for the next 15 minutes before medical teams arrived and whisked Estepa away.Two days later, when Estepa woke up in the hospital, he was shocked to learn he had gone into cardiac arrest (心脏停搏). How did this happen, and,why was he lucky enough to have survived? He was full of gratitude and needed to speak with the woman who had saved him, whom he named his “angel”.“It was emotional,” says Arthur of her meeting with Estepa a few weeks later. Saving his life had extra importance for her: the hike she was returning from that day was one of 100 hikes she’s planned to honour her father, who died in 2017 after he fell during a hike that Arthur was meant to be on. “I couldn’t save my father’s life,” Arthur says, “but this was a chance for me to save someone.”()1.Why did Mike Estepa stop while riding?A.He suffered a heart attack.B.He wanted to send a message.C.He would like to lie in the ditch.D.He was too far away from his home.()2.What do we know about Arthur?A.She was an amateur nurse.B.She was scared of ants.C.She knew how to do CPR.D.She went cycling with a friend.()3.What did Arthur think of her saving Estepa?A.Grateful.B.Lucky.C.Significant.D.Natural.()4.What’s the best title of the text?A.A miracle to return to lifeB.An angel on the roadsideC.A risky cycling aloneD.A chance to save lifeB主题词数体裁大象无长牙345 说明文While elephants born without tusks(长牙) are not unheard-of, they normally are made up of just 2 to 6 per cent of the population. However, that is not the case at Mozambique’s Gorongosa National Park, where 33 per cent of female elephants born after the country’s civil war ended in 1992 are tuskless.This is not the first time researchers have observed a serious change in the population of elephants that have suffered severe poaching(偷猎) losses. At the Ruaha National Park in Tanzania, 35% of elephants 25 years or older and 13% of those younger than 25 are now without tusks. A 2008 study published in the African Journal of Ecology found that the number of tuskless females atZambia’s South Luangwa National Park went from 10.5 per cent in 1969 to almost 40 per cent in 1989, largely due to illegal hunting for ivory.Thus far, the result of poaching has largely affected female elephants. Poole explains, “Because males require tusks for fighting, tusklessness has been selected against in males, and very few males are tuskless. For African elephants, tuskless males have a much harder time breeding and do not pass on their genes(基因) as often as tusked males.”However, if the killing of males with the most impressive tusks continuesat this pace, it could result in a generation of elephants with much smaller tusks. Poole says, “If poachers select according to the size of tusks, they will tend tokill older males with very large tusks, therefore taking out of the population of breeding-aged males who also happen to have very big tusks. Those males then no longer pass on their genes for large tusks. In this manner, heavy poachingwill select out genes for large tusks.”The recent ban on ivory in both the US and China should help eliminate, or at least reduce, elephant poaching. However, scientists are not sure how long it will take for the elephants with a higher rate of tuskless females to reverse the trend.()5.What is the function of the first paragraph?A.To make comparisons.B.To introduce the topic.C.To appeal to attention.D.To give readers a surprise.()6.What may cause tuskless females to increase in Zambia?A.War’s effect.B.Imperfect management.C.Illegal hunting.D.The decrease of population.()7.What can we learn from what Poole says?A.Tuskless elephants are being neglected.B.Heavy poaching for large tusks will be forbidden.C.Tusklessness influences the heredity(遗传) of male elephants.D.Older males with very large tusks are soon dying out.()8.What does the underlined word “eliminate” in Parag raph 5 mean? A.Remove. B.Decline.pete.D.Unite.Ⅱ.完形填空主题词数体裁营救座头鲸290 记叙文A humpback whale was struggling hard in the sea. The humpbacks can weigh 40 tons and stretch 50 feet from nose to tail. That’s the kind of 1 and size that easily overturn small boats. To jump onto the 2of one ofthese giants is 3to result in a disaster.

(推荐时间：45分钟)一、选择题1． 设A ，B 是非空集合，定义A ×B ＝{x |x ∈(A ∪B )且x ∉(A ∩B )}，已知A ＝{x |0≤x ≤2}，B＝{y |y ≥0}，则A ×B 等于( )A ．(2，＋∞)B ．[0,1]∪[2，＋∞)C ．[0,1)∪(2，＋∞)D ．[0,1]∪(2，＋∞)答案 A解析 由题意知，A ∪B ＝[0，＋∞)，A ∩B ＝[0,2]． 所以A ×B ＝(2，＋∞)．2． 命题“对任意的x ∈R ，x 3－x 2＋1≤0”的否定是( )A ．不存在x ∈R ，x 3－x 2＋1≤0B ．存在x ∈R ，x 3－x 2＋1≥0C ．存在x ∈R ，x 3－x 2＋1>0D ．对任意的x ∈R ，x 3－x 2＋1>0 答案 C3． 给出下面四个命题：①“直线a ∥直线b ”的充要条件是“a 平行于b 所在的平面”； ②“直线l ⊥平面α内所有直线”的充要条件是“l ⊥平面α”；③“直线a ，b 为异面直线”的充分不必要条件是“直线a ，b 不相交”；④“平面α∥平面β”的必要不充分条件是“α内存在不共线三点到β的距离相等”． 其中正确命题的序号是( )A ．①②B ．②③C ．③④D ．②④答案 D解析 当a 平行于b 所在平面时，a ，b 可能异面，故①不正确；当a 、b 不相交时，可能a ∥b ，故③不正确；由此可排除A 、B 、C ，故选D.4． 设向量a ＝(cos α，sin α)，b ＝(cos β，sin β)，其中0<α<β<π，若|2a ＋b |＝|a －2b |，则β－α等于( )A.π2B ．－π2C.π4D ．－π4答案 A解析 由|2a ＋b |＝|a －2b |得3|a |2－3|b |2＋8a·b ＝0，而|a |＝|b |＝1，故a·b ＝0，即cos(α－β)＝0，由于0<α<β<π，故－π<α－β<0，故α－β＝－π2，即β－α＝π2.选A.5． 已知{a n }为等差数列，其公差为－2，且a 7是a 3与a 9的等比中项，S n 为{a n }的前n 项和，则S 10的值为( )A ．－110B ．－90C ．90D ．110答案 D解析 a 7是a 3与a 9的等比中项，公差为－2， 所以a 27＝a 3·a 9，所以a 27＝(a 7＋8)(a 7－4)，所以a 7＝8，所以a 1＝20，所以S 10＝10×20＋10×92×(－2)＝110.6． 设双曲线x 2a 2－y 2b2＝1(a >0，b >0)的渐近线与抛物线y ＝x 2＋1相切，则该双曲线的离心率等于( )A. 3B ．2C. 5D. 6答案 C解析 设切点P (x 0，y 0)，则切线的斜率为y ′|x ＝x 0＝2x 0. 由题意有y 0x 0＝2x 0，又y 0＝x 20＋1，解得x 20＝1，所以ba ＝2，e ＝1＋⎝⎛⎭⎫b a 2＝ 5.7． 设随机变量ξ服从正态分布N (16，σ2)，若P (ξ>17)＝0.35，则P (15<ξ<16)＝( )A ．0.35B ．0.85C ．0.3D ．0.15答案 D解析 由正态分布的对称性知，P (ξ>16)＝0.5， 又P (ξ>17)＝0.35，所以P (16<ξ<17)＝0.5－0.35＝0.15. 于是P (15<ξ<16)＝P (16<ξ<17)＝0.15.8． 若某空间几何体的三视图如图所示，则该几何体的体积是( )A ．4 2B ．2 2C.423 D.223答案 B解析 该几何体是底面是直角三角形的直三棱柱，由三棱柱体积公式V ＝S底h 可得V＝2 2.9． 设函数f (x )＝sin(ωx ＋φ)＋cos(ωx ＋φ)⎝⎛⎭⎫ω>0，|φ|<π2的最小正周期为π，且f (－x )＝f (x )，则( )A ．y ＝f (x )在⎝⎛⎭⎫0，π4上单调递减 B ．y ＝f (x )在⎝⎛⎭⎫π4，3π4上单调递减 C ．y ＝f (x )在⎝⎛⎭⎫0，π2上单调递增 D ．y ＝f (x )在⎝⎛⎭⎫π4，3π4上单调递增 答案 A解析 变形f (x )＝sin(ωx ＋φ)＋cos(ωx ＋φ) ＝2sin ⎝⎛⎭⎫ωx ＋φ＋π4. 又f (－x )＝f (x )，得函数为偶函数，故φ＋π4＝k π＋π2(k ∈Z )．∴φ＝k π＋π4(k ∈Z )．∵|φ|<π2，∴φ＝π4.又T ＝π，∴ω＝2.∴f (x )＝2sin ⎝⎛⎭⎫2x ＋π2＝2cos 2x . 结合图象知A 正确．10．(2013·山东)函数y ＝x cos x ＋sin x 的图象大致为( )答案 D解析 函数y ＝x cos x ＋sin x 为奇函数，排除B.取x ＝π2，排除C ；取x ＝π，排除A ，故选D.11．设m >1，在约束条件⎩⎪⎨⎪⎧y ≥x ，y ≤mx ，x ＋y ≤1下，目标函数z ＝x ＋my 的最大值小于2，则m 的取值范围为( )A ．(1,1＋2)B ．(1＋2，＋∞)C ．(1,3)D ．(3，＋∞)答案 A解析 画出可行域，可知z ＝x ＋my 在点⎝⎛⎭⎫11＋m ，m1＋m 取最大值，由11＋m ＋m 21＋m<2解得1<m <1＋ 2. 12．函数f (x )的定义域为R ，f (－1)＝2，对任意x ∈R ，f ′(x )>2，则f (x )>2x ＋4的解集为( )A ．(－1,1)B ．(－1，＋∞)C ．(－∞，－1)D ．(－∞，＋∞)答案 B解析 f ′(x )>2转化为f ′(x )－2>0， 构造函数F (x )＝f (x )－2x ， 得F (x )在R 上是增函数．又F (－1)＝f (－1)－2×(－1)＝4，f (x )>2x ＋4， 即F (x )>4＝F (－1)，所以x >－1. 二、填空题13．若直线y ＝kx －1与圆x 2＋y 2＝1相交于P 、Q 两点，且∠POQ ＝120°(其中O 为原点)，则k 的值为________． 答案 ±3解析 圆心O 到直线y ＝kx －1的距离d ＝1k 2＋1＝12， ∴k ＝±3.14．若执行如图所示的程序框图，输入x 1＝1，x 2＝2，x 3＝3，x ＝2，则输出的数等于________．答案 23解析 通过框图可以看出本题的实质是求x 1，x 2，x 3的方差，根据方差公式得 输出S ＝13[(1－2)2＋(2－2)2＋(3－2)2]＝23.15．若圆x 2＋y 2－4x －4y －10＝0上至少有三个不同点到直线l ：ax ＋by ＝0的距离为22，则直线l 的斜率的取值范围是________． 答案 [2－3，2＋3]解析 圆x 2＋y 2－4x －4y －10＝0可转化为(x －2)2＋(y －2)2＝(32)2，∴圆心的坐标为(2,2)，半径为32，要求圆上至少有三个不同的点到直线l ：ax ＋by ＝0的距离为22，则圆心到直线l 的距离应小于等于2， ∴|2a ＋2b |a 2＋b 2≤2，∴⎝⎛⎭⎫a b 2＋4⎝⎛⎭⎫a b ＋1≤0，∴－2－3≤a b ≤－2＋3，又直线l 的斜率k ＝－ab ，∴2－3≤k ≤2＋3，即直线l 的斜率的取值范围是[2－3，2＋3]． 16．已知如下等式：3－4＝17(32－42)，32－3×4＋42＝17(33＋43)，33－32×4＋3×42－43＝17(34－44)，34－33×4＋32×42－3×43＋44＝17(35＋45)，则由上述等式可归纳得到3n －3n －1×4＋3n －2×42－…＋(－1)n 4n ＝________(n ∈N *)．答案17[]3n ＋1－(－4)n ＋1。
