．2C ．0D ．﹣2解：根据题意，f(x)={x 2+2x ，x ＜32x−2，x ≥3，则f （1）＝1+2＝3，则f （f （1））＝f （3）=23−2=2． 故选：B ．3．命题“∀x ∈R ，x 2+3x ＞0”的否定是（ ） A ．∀x ∈R ，x 2+3x ≤0 B ．∀x ∈R ，x 2+3x ＜0 C ．∃x ∈R ，x 2+3x ≤0D ．∃x ∈R ，x 2+3x ＜0解：“∀x ∈R ，x 2+3x ＞0”的否定是：∃x ∈R ，x 2+3x ≤0． 故选：C ．4．下列函数中，在其定义域内既是奇函数又是增函数的为（ ） A ．y =1xB ．y ＝x +1C ．y ＝|x |D ．y ={x 2+x ，x ≥0−x 2+x ，x ＜0解：对于A 项，函数y =1x 是奇函数，但是y =1x 在（﹣∞，0）和（0，+∞）上单调递减， 在定义域上不具有单调性，不符合题意；对于B 项，函数y ＝f （x ）＝x +1在R 上单调递增，但是f （﹣x ）＝﹣x +1，而﹣f （x ）＝﹣x ﹣1， 故y ＝x +1不是奇函数，不符合题意；对于C 项，设f （x ）＝|x |，因为f （﹣x ）＝|﹣x |＝|x |＝f （x ），且定义域为R ， 所以函数y ＝|x |是偶函数，不符合题意； 对于D 项，函数y =f(x)={x 2+x ，x ≥0−x 2+x ，x ＜0，f （﹣x ）={−x 2−x ，x ≥0x 2−x ，x ＜0=−f （x ），所以f （x ）为奇函数，f （x ）的图象如图：故y ={x 2+x ，x ≥0−x 2+x ，x ＜0既是奇函数，又是增函数，符合题意．故选：D ．5．已知y ＝x 2+3x +1，x ∈[﹣2，1]，则y 的取值范围为（ ） A ．[﹣1，5]B ．[−54，−1]C ．[−54，5]D ．[−54，+∞)解：y ＝x 2+3x +1，开口向上，对称轴方程为x =−32， 因为x ∈[﹣2，1]，−32∈[﹣2，1]，所以f （x ）min ＝f （−32）＝（−32）2+3×（−32）+1=−54，又因为|1﹣（−32）|＞|﹣2﹣（−32）|，所以f （x ）max ＝f （1）＝12+3×1+1＝5． 故函数的值域为[−54，5]． 故选：C ．6．下列结论正确的是（ ）A ．当x ＞0且x ≠1时，x +1x 的最小值为2 B ．当x ＞1时，√x +1√x的最小值为2 C ．当x ≠0时，x +1x 的最小值为2D ．当x ≠0时，x 2+1x 2的最小值为2 解：x ＞0且x ≠1时，x +1x ＞2，A 错误； 当x ＞1时，t =√x ＞1，y ＝t +1t＞2，B 错误； 当x ＜0时，C 显然错误； 当x ≠0时，x

＞0的解集为{x|x ＞12，或x ＜−13}解：记f （x ）＝ax 2+bx +c ，因为1∈{x |﹣3＜x ＜2}，所以f （1）＝a +b +c ＞0，故A 错误； 因为3∉{x |﹣3＜x ＜2}，所以f （3）＝9a +3b +c ＜0，故B 错误；由题知﹣3和2是方程ax 2+bx +c ＝0的两个实根，所以−ba =−3+2=−1，ca=−3×2=−6，且a ＜0，解得b ＝a ，c ＝﹣6a ，故cx 2+ax +b =−a(6x 2−x −1)＞0⇔6x 2−x −1＞0⇔x ＞12或x ＜−13，C 错误；cx 2+bx +a =−a(6x 2−x −1)＞0⇔6x 2−x −1＞0⇔x ＞12或x ＜−13，D 正确． 故选：D ．8．设函数f （x ）的定义域为R ，满足f （x ）＝2f （x ﹣2），且当x ∈（0，2]时，f （x ）＝x （2﹣x

）＝2f （x ﹣2）＝2（x ﹣2）[2﹣（x ﹣2）]＝﹣2（x ﹣3）2+2∈[0，2]， 当x ∈（4，6]时，x ﹣4∈（0，2]，则f （x ）＝4f （x ﹣4）＝4（x ﹣2﹣2）[4﹣（x ﹣2）]＝﹣4（x ﹣5）2+4∈[0，4]， 当x ∈（﹣2，0]时，x +2∈（0，2]，则f （x ）=12f （x +2）=12（x +2）（﹣x ）=−12（x +1）2+12∈[0，12]，作出函数f （x ）的大致图象，如图所示：对任意x ∈（﹣∞，m ]，都有f （x ）≤3， 设m 的最大值为t ，则f （t ）＝3， 所以﹣4（t ﹣5）2+4＝3，解得t =92或t =112， 结合图象知m 的最大值为92，即m 的取值范围是（﹣∞，92]．故选：C ．二、多选题（本大题共4小题，每小题5分，共20分．每小题各有四个选项，有多个选项正确，请用2B 铅笔把答题卡中所选答案的标号涂黑）9．下列元素与集合的关系中，正确的是（ ） A ．﹣1∈NB ．0∉N *C ．√2∉QD ．π∉Q解：对于A ，因为﹣1不是自然数，所以A 错误； 对于B ，因为0不是正整数，所以B 正确： 对于C ，因为√2不是有理数，所以C 正确； 对于D

错误；由①得，b 2＜c 2，ab 2＜ac 2，D 正确． 故选：ACD ．11．已知函数f （x ）在R 上单调递减，且为奇函数，f （1）＝﹣1，则满足|f （x 2﹣1）|≤1的x 值可能为（ ） A ．﹣1B ．0C ．1D ．2解：因为函数f （x ）在R 上单调递减，且为奇函数，f （1）＝﹣1，则f （﹣1）＝﹣f （1）＝1， |f （x 2﹣1）|≤1可转化为﹣1≤f （x 2﹣1）≤1， 所以﹣1≤x 2﹣1≤1， 解得−√2≤x ≤√2． 故选：ABC ．12．已知函数f(x)={x 2+2ax +11，x ≤2a 1−x ，x ＞2满足对任意x 1≠x 2，都有f(x 1)−f(x 2)x 1−x 2＜0成立，则实数a 的值可能为（ ） A ．﹣3B ．﹣2C ．﹣1D ．0解：因为f(x)={x 2+2ax +11，x ≤2a 1−x ，x ＞2满足对任意x 1≠x 2，都有f(x 1)−f(x 2)x 1−x 2＜0成立，所以f （x ）在R 上单调递减，所以{−a ＞0−a ≥24+4a +11≥a1−2，解得﹣3≤a ≤﹣2．故选：AB ．三、填空题：本大题共4小题，每小题5分，共20分． 13．函数y =1x +√x −4的定义域为 [4，+∞） ． 解：要使函数有意义，则{x −4≥0x ≠0，即x ≥4，故函数的定义域为[4，+∞）．

（x ）＝x 2+bx +c 为偶函数”的充要条件． 故答案为：充要．15．已知当x ＞0时，关于x 的不等式ax 2﹣x +a ≤0有解，则a 的最大值为 12．解：关于x 的不等式ax 2﹣x +a ≤0在x ∈（0，+∞） 有解， 即a （x 2+1）≤x 在x ∈（0，+∞） 有解，也即a ≤xx 2+1在x ∈（0，+∞）有解，记f(x)=xx 2+1，x ＞0，则a ≤f （x ）max ，因为x ＞0，所以f(x)=x x 2+1=1x+1x≤12√x⋅1x=12， 当且仅当x =1x，即x ＝1时等号成立，所以a ≤12，即a 的最大值为12．故答案为：12．16．用max {a ，b }表示a ，b 两个数中的最大值，设函数f(x)=max{|x|+4，6x−x}(x ＞0)，若f （x ）≥m +2恒成立，则m 的最大值是 3 ．解：因为x ＞0，由x +4≥6x −x ，得x ≤﹣3或x ≥1， 则f （x ）＝max {|x |+4，6x −x }={x +4，x ≥16x−x ，0＜x ＜1，当x ≥1时，f （x ）≥5； 当0＜x ＜1时，f （x ）=6x−x 单调递减，则f （x ）＞5， 综上，当x ＞0时，f （x ）≥5， 又因为f （x ）≥m +2恒成立， 即5≥m +2，解得m ≤3， 则m 的最大值是3．

）＝{x |﹣2＜x ≤0}； （2）∵A ∩B ＝A ，∴A ⊆B ， ∴{2−m ≤−22+m ≥3， 解得m ≥4，即实数m 的取值范围为[4，+∞）．18．（12分）（1）已知a ＝2x 2+3x +2，b ＝x 2﹣x ﹣2，比较a ，b 的大小并说明原因； （2）已知a ＞0，b ＞0，且a +b ＝1，求1b+ba 的最小值．解：（1）a ﹣b ＝x 2+4x +4＝（x +2）2≥0， ∴a ≥b ．（2）由题可知1b +b a=a+b b +b a=1+a b+b a≥1+2√a b ⋅b a=3，当且仅当a b=ba，即a ＝b =12时，等号成立，∴1b+ba的最小值为3．19．（12分）已知二次函数f （x ）对应方程f （x ）＝0的解分别为1和3，且f （0）＝﹣3． （1）求函数f （x ）的解析式；（2）解关于x 的不等式f （x ）＞1﹣m 2（m ∈R ）． 解：（1）由已知可设f （x ）＝a （x ﹣1）•（x ﹣3）（a ≠0）， 又因为f （0）＝﹣3，所以3a ＝﹣3， 即a ＝﹣1，所以f （x ）＝﹣x 2+4x ﹣3；（2）由（1）知f （x ）＝﹣x 2+4x ﹣3， 由题意可得﹣x 2+4x ﹣3＞1﹣m 2，即x 2﹣4x +4﹣m 2＜0，整理可得（x +m ﹣2）（x ﹣m ﹣2）＜0， 因为方程（x +m ﹣2）（x ﹣m ﹣2）＝0的根为2+m ，2﹣m ，当2+m ＝2﹣m ，即m ＝0时，不等式为（x ﹣2）2＜0，不等式的解集为∅； 当2﹣m ＜2+m ，即m ＞0时，则不等式的解集为（2﹣m ，2+m ）； 当2﹣m ＞2+m ，即m ＜0，则不等式的解集为（2+m ，2﹣m ）．综上所述：当m＝0，不等式的解集为∅；当m＞0，不等式的解集（2﹣m，2+m）；当m＜0，不等式的解集（2+m，2﹣m）．20．（12分）下表为某市居民用水阶梯水价表（单位：元/立方米）．（1）试写出用户所交水费为y（元）与用水量为x（立方米）的函数关系式；（2）若某户居民一年交水费1110元，求其中水资源费和污水处理费分别为多少？解：（1）依题意，当0≤x≤180时，y＝5x，当180＜x≤260时，y＝7（x﹣180）+900＝7x﹣360，当260＜x时，y＝9（x﹣260）+900+560＝9x﹣880，所以，用户所交水费为y（元）与用水量为x（立方米）的函数关系式是：y={5x，x∈[0，180]7x−360，x∈(180，260]9x−880，x∈(260，+∞)；（2）当5x＝1110时，则x＝220∉[0，180]，不符合题意，当7x﹣360＝1110时，则x＝210∈（180，260），符合题意，当9x﹣880＝1110时，则x=19909∉(260，+∞)，不符合题意，所以x＝210，则水资源费为1.5×210＝315元，污水处理费为1.4×210＝294元．21．（12分）已知函数f(x)=ax+b9−x2是定义在（a，b+3）上的奇函数．（1）求实数a和b的值；（2）判断函数f（x）在（a，b+3）上的单调性，并证明你的结论；（3）f（m2﹣1）+f（m﹣1）＞0，求m的取值范围．解：（1）由题已知{f(0)=b=0 9a+b+3=0，解得a＝﹣3，b＝0；（2）由（1）知f(x)=−3x9−x2，定义域为（﹣3，3），函数f （x ）在（﹣3，3）上单调递减，理由如下：∀x 1，x 2∈（﹣3，3），且x 1＜x 2，则f(x 1)−f(x 2)=−3x 19−x 12−−3x 29−x 22=(x 1−x 2)(3x 1x 2−27)(9−x 12)(9−x 22) ∵﹣3＜x 1＜x 2＜3，∴9−x 12＞0，9−x 22＞0，x 1﹣x 2＜0，3x 1x 2﹣27＜0，∴f （x 1）﹣f （x 2）＞0，即f （x 1）＞f （x 2），∴函数f （x ）在（﹣3，3）上单调递减．（3）∵f （x ）为奇函数，f （m 2﹣1）+f （m ﹣1）＞0，∴f （m 2﹣1）＞﹣f （m ﹣1）＝f （1﹣m ），又由（2）知f （x ）在（﹣3，3）上单调递减，∴{m 2−1＜1−m−3＜m −1＜3−3＜m 2−1＜3，解得m ∈（﹣2，1）．22．（12分）已知函数f （x ）＝2x 2﹣ax +a 2﹣4，g(x)=x 2−x +a 2−314，（a ∈R ） （1）当a ＝1时，解不等式f （x ）＞g （x ）；（2）若任意x ＞0，都有f （x ）＞g （x ）成立，求实数a 的取值范围；（3）若∀x 1∈[0，1]，∃x

＞0恒成立， 解一：设ℎ(x)=x 2+(1−a)x +154，x ＞0，则函数h （x ）的对称轴为x =a−12，由题意，只须h （x ）min ＞0， ①当a−12≤0，即a ≤1时，h （x ）在（0，+∞）上单调递增，所以ℎ(x)＞ℎ(0)=154，符合题意，所以a ≤1；②当a−12＞0，即a ＞1时，h （x ）在(0，a−12)上单调递城，在(a−12，+∞)单调递增， 所以ℎ(x)＞ℎ(a−12)=−(a−1)24+154＞0，解得1−√15＜a ＜1+√15且a ＞1，所以1＜a ＜1+√15．综上a ＜1+√15，即实数a 的取值范围为：（﹣∞，1+√15）； 解二：不等式可化为(a −1)x ＜x 2+154（x ＞0）， 即a −1＜x +154x ，设k =x +154x，x ＞0由题意，只须a ﹣1＜k min ， 根据基本不等式，可知k =x +154x ≤2√x ⋅154x =√15，即k min =√15，当且仅当x =√152时，等号成立，所以a ﹣1＜√15，a ＜1+√15，即实数a 的取值范围为：（﹣∞，1+√15）；（3）若对任意x 1∈[0，1]，存在x 2∈[0，1]，使得不等式f （x 1）＞g （x 2）成立， 即只需满足f （x ）min ＞g （x ）min ，x ∈[0，1]， 因为g(x)=x 2−x +a 2−314，对称轴x =12， 所以g （x ）在[0，12)递减，在(12，1]递增， 所以g(x)min =g(a 2)=a 2−8，f （x ）＝2x 2﹣ax +a 2﹣4，x ∈[0，1]，对称轴x =a 4， ①a 4≤0，即a ≤0时，f （x ）在[0，1]递增，f(x)min =f(0)=a 2−4＞g(x)min =a 2−8恒成立； ②0＜a 4＜1，即0＜a ＜4时，f （x ）在[0，a 4)递减，在(a 4，1]递增， 所以f(x)min =f(a 4)=78a 2−4，g(x)min =a 2−8， 所以78a 2−4＞a 2−8， 故0＜a ＜4；③a 4≥1，即a ≥4时，f （x ）在[0，1]递减， 所以f(x)min =f(1)=a 2−a −2，g(x)min =a 2−8， 所以a 2﹣a ﹣2＞a 2﹣8，解得4≤a ＜6，综上：实数a 的取值范围为（﹣∞，6）．。

I was amazed that each one knew ____what to do. After hours of staring, I realized that the ants had assigned jobs. With my mom ' s help, I kept a diary of what happened each day and ____ the ants. My favorite was the biggest , Cinderella.

Unfortunately, my carelessness caused all the tunnels to ____. Although the ants ____ their earthquake, one by one they began to die. I was ____ as I watched them give up their tunnel-building to carry the bodies to a corner of the farm.

They simply could not ____ the reality that their tunnels had been destroyed. Cinderella was the last to die ---she did so while carrying a dead ant on her back .Although much time has passed, I still think of that ant farm. Mom had hoped it would teach me about the natural world, ____ it taught me much more.____ the years, I came to realize the ants were a study in the benefits of ____.

A new collection of photos brings an unsuccessful Antarctic voyage back to life.Frank Hurley's pictures would be outstanding—undoubtedly first-rate photo-journalism—if they had been made last week.In fact，they were shot from 1914 through 1916, most of them after adisastrous shipwreck(海难), by a cameraman who had no reasonable expectation of survival.Many of the images were stored in an ice chest, under freezing water, in the damaged wooden ship.The ship was the Endurance, a small, tight, Norwegian-built three-master that was intended to take Sir Ernest Shackleton and a small crew of seamen and scientists, 27 men in all，to the southernmost shore of Antarctica's Weddell Sea.From that point Shackleton wanted to force a passage by dog sled (雪橇) across the continent.The journey was intended to achieve more than what Captain Robert Falcon Scott had done.Captain Scott had reached the South Pole early in 1912 but had died with his four companions on the march back.As writer Caroline Alexander makes clear in her forceful and well-researched story The Endurance, adventuring was even then a thoroughly commercial effort.Scott's last journey，completed as he lay in a tent dying of cold and hunger, caught the world's imagination, and a film made in his honor drew crowds.Shackleton, a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908, started a business before his 1914 voyage to make money from movie and still photography.Frank Hurley, a confident and gifted Australian photographer who knew the Antarctic，was hired to make the images, most of which have never before been published.1. What do we know about the photos taken by Hurley?A．They were made last week.B．They showed undersea sceneries.C．They were found by a cameraman.D．They recorded a disastrous adventure.2. Who reached the South Pole first according to the text?A．Frank Hurley.B．Ernest Shackleton.C．Robert Falcon Scott.D．Caroline Alexander.3. What does Alexander think was the purpose of the 1914 voyage?A．Artistic creation. B．Scientific research.C．Money making. D．Treasure hunting.23. The latest discovery in cat research reveals that the lovely animal seems to have a basic grasp on both the laws of physics and the ins and outs of cause and effect.According to a newly published study, cats seem to be able to predict the location of hiding prey (猎物) using both their ears and an inborn understanding of how the physical world works.In a recent experiment, Japanese researchers taped 30 domestic cats reacting to a container that a team member shook. Some containers rattled; others did not. When the container was tipped over, sometimes an object fell out and sometimes it did n’t.It turns out that the cats were remarkably smart about what would happen when a container was tipped over. When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected.“Cats use a causal-logical understanding of noise or sounds to predict the appearance of invisible objects,” lead researcher Saho Takagi says in a press release. The researchers conclude that cats’ hunting style may have developed based on their common-sense abilities to infer where prey is, using their hearing.Scientists have explored this idea with other endearing creatures: babies. Like cats, babies appear to engage in what’s called “preferential looking”—looking longer at things that are interesting or unusual than things they perceive (认知) as normal.When babies’ expectations are violated in experiments like the ones performed with the cats, they react much like their animal friends. Psychologists have shown that babies apparently expect their world to obey the laws of physics and cause and effect as early as two months of age.Does the study mean that cats will soon grasp the ins and outs of cause and effect? Maybe, Okay, so cats may not be the next physics faculty members at America’s most important research universities. But by demonstrating their common sense, they’ve shown that the divide between cats and humans may not be that great after all.1. What do we learn from a newly published study about cats?A．They can be trained to understand the physical world.B．They have a natural ability to locate animals they hunt.C．They know what kind of prey might be easier to hunt.D．They are capable of telling which way their prey flees.2. What may account for the cats’ response to the noise from the containers?A．Their command of cause and effect. B．Their unusual sense of direction.C．Their special ability to perceive. D．Their inborn sensitivity to noise.3. What can we conclude about cats from the passage?A．They have higher intelligence than the majority of animals.B．They display outstanding abilities in hunting and hearing.C．They can aid physics professors in their research work.D．They interact with the physical world much like humans.24. The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don’t know. By next year, half of the calls we receive will be scams (欺诈). We are finally waking up to the severity (严重性) of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it’s too little, too late. By the time these “solutions” become widely available (有效的), scammers will have moved onto cleverer means. In the near future, it’s not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you’re hearing is actually real.That’s because there are a number of powerful voice manipulation (处理) and automation technologies that are about to become widely available for anyone to use. At this year’s I/O Conference, a company showed a new voice technology able to produce such a convincing human—sounding voice that it was able to speak to a receptionist (接待员) and book a reservation without detection.These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data breaches (数据侵入) of personal information has led to a situation where scammers can easily learn your mother’s name, and far more. Armed with this knowledge, they’re able to carry out individually targeted campaigns (活动) to cheat people. This means. for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller’s, ricking you into “confirming” your address, mother’s name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by or abandoning phone calls altogether and moving towards data-based communications—using apps like Face Time or WhatsApp, which can be tied to your identity. Credibility is hard to earn but easy to lose, and the problem is only going to harder from here on out.1. How does the author feel about the solutions to problem of robocalls?A．Terrified B．Confused.C．Embarrassed. D．Disappointed.2. Taking advantage of the new technologies, scammer can ______.A．aim at victims precisely B．damage databases easilyC．start campaigns rapidly D．spread information widely3. What does the passage imply?A．Honest y is the best policy.B．Technologies can be double-edited.C．There are more solutions than problems.D．Credibility holds the key to development.4. Which of the following would be the best title for the passage?A．Where the Problem of Robocalls Is RootedB．Who Is to Blame for the Problem of RoboeallsC．Why Robocalls Are About to Get More DangerousD．How Robocalls Are Affecting the World of Technology25. Speed-reading is a necessary skill in the Internet age. We skim over articles, e-mails and WeChat to try to grasp key words and the essential meaning of a certain text. Surrounded with information from our electronic devices, it would be impossible to cope if we read word by word, line by line. 1A recent story from The Wall Street Journal reported on a book club in Wellington, New Zealand, where members meet in a cafe and turn off their smartphones. 2 The point of the slow reading club is to get away from electronic devices and read in a quiet, relaxed environment.Slow reade rs, such as the Atlantic’s Maura Kelly, say a regular reading habit sharpens the mind, improves concentration, reduces stress levels and deepens the ability to sympathize. 3 And this is a fundamental skill in building relationships.4 Screens have changed our reading patterns from the top-to-bottom, left-to-right reading order we traditionally used, to a wild skimming and skipping pattern as we hunt for important words and information. Because of the Internet, we may have become very good at collecting a wide range of interesting news, but we are also gradually forgetting how to sit back, reflect, and relate all these facts to each other.Slow reading means a return to an uninterrupted, straight pattern, in a quiet environment free of distractions. 5 “You can squeeze in that half hour pretty easily if only during your free moments, you pick up a meaningful work of literature,” Kelly said. “Reach for your e-reader, if you like. Kindles make books like War and Peace less heavy, not less substantive, and a lso ensure you’ll never lose your place.”26. 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
