2018“超级全能生”3月联考Word版含答案。

2018届高考全国卷26省3月联考乙卷数学(理)试题超级全能生”是2018年高考全国卷26省3月联考乙卷(A)数学(理科)的一道题目。

本试题共12小题,每小题5分,共60分。

考生需在答题卡上完成全部答案,答在本试题上无效。

选择题中,每小题给出四个选项,只有一项符合题目要求。

第一题给出两个集合A和B,要求求出A并B的结果。

通过题干中给出的条件,可以得到A的元素为a和0,B的元素为-4和log2(a+3)。

由于A并B的结果为2,因此可以列出方程a+3=2,解得a=-1.因此,A的元素为-1和0,B的元素为-4和log2(2)。

因此,A并B的结果为{-1,0,-4},答案为A。

第二题要求求解一个纯虚数z,已知z(1-i)=a+i(a∈R)。

可以将z表示为x+yi的形式,其中x=0,y为所求。

将z代入方程中,可以得到-y+xi=a+ai。

由于z是纯虚数,因此实部为0,因此可以得到-y=a。

将y代入方程中,可以得到x=a。

因此,z 的形式为a-ai,答案为D。

第三题给出两个向量a和b,已知它们平行,求出a的第一个分量m。

可以列出方程m/b1=1,解得m=b1.因此,m=11,答案为A。

第四题给出一个函数f(x),要求画出其大致图像。

可以将f(x)表示为2x/x2+x,通过对x趋于正无穷和负无穷时的极限值,可以画出f(x)的大致图像,如下图所示。

第五题给出一个等比数列和的关系式,要求求出S2017.通过将等式两边展开,可以得到a2S4=a4S2,即a2(a1+ar)(a1+a2+。

+a4)=a4(a1+ar)(a1+a2+。

+a2),其中r为等比数列的公比。

化简后可以得到a2=a4/r2,代入S2017的表达式中,可以得到S2017=a1(1-r2017)/(1-r)。

由于未给出等比数列的首项和公比,因此无法求出S2017,答案为D。

第六题给出六个人进行羽毛球双打练,求出不同的分组方式数量。

“超级全能生”2018届高三全国卷26省3月联考乙卷英语试题学校:___________姓名:___________班级:___________考号:___________一、阅读选择When Kyle Jauregui recently went to pick up his younger sister’s birthday cake, he was met with a bittersweet surprise.On arriving at the baker’s, he learnt that Madison s cake had already been paid for —by a complete stranger. It was a touching act of kindness, but, as it turned out, not a random one. The cake had been paid for by a lady known simply as “McKenna’s mum” -as part of a gesture she had been making for a while, and for a heartbreaking reason.While Madison is set to celebrate turning 11, McKenna Jodell Fox would have turned ten on the same day. McKenna was only nine months old in 2008, when she was crushed by a falling TV set as her family prepared to move house.It’s a painful occasion for her mum, but one she has transformed into something positive. The cake she bought was accompanied by a card which read as follows:“Dear Birthday Girl Family,In honour of my daughter’s 10th birthday I hav e chosen your birthday cake to pay for.Each year I do this random act of kindness because I am unable to buy my daughter a cake of her own.Today is her big double digit birthday. Please enjoy your day.”By Kyle’s own admission, the whole family was left speechless. “We just want to say thank you to McKenna’s mom,” he wrote, “and wish McKenna a happy birthday. There’s still good in this world.”1.Who died according to the passage?A.Kyle Jauregui. B.Madison.C.McKenna Jodell Fox. D.McKenna’s mum.2.What do we know about the birthday cake?A.It tasted bittersweet.B.It was paid by McKenna’s mum.C.It made the family heartbroken.D.It was free of charge.3.Which of the following can best describe McKenna’s mum?A.Warm-hearted and cheerful. B.Strong-willed but depressed. C.Broken-hearted but generous. D.Kind-hearted and positive.4.Which of the following would be the best title for the text?A.A Painful Accident B.A Family Left SpeechlessC.One Birthday Cake for Two Girls D.A World Full of SurprisesUh-oh-you’re stuck with a long mid-journey stay or an insane flight delay. What to do? Spending hours in an airport can make any person who travels by plane a little annoyed. But before you splurge (挥霍) at the bar or duty-free shops, you might want to ask about your airport’s perks (特权).There are a lot of things you can do in the airport without breaking the bank.To reduce your annoyance and save your wallet, VIV A Lifestyle and Travel has compiled a list of all of the best airport perks. Make sure you’re not making these mistakes on your next flight, too.Some airports, such as Portland International Airport in Oregon, San Francisco International Airport in California, or Minneapolis-St. Paul International Airport, offer free movies to waiting passengers. Others have free museums and live events, including San Francisco, Miami, Albany, Minneapolis, Portland, and St. Louis.Looking to relax after a stressful trip? Many airports offer therapy dogs; you can also visit the pig at San Francisco International Airport, the cat at Denver International Airport, and the miniature horses at Cincinnati’s airport. If you’re flying through San Francisco, Chicago, Miami, or Dallas Fort Worth, borrow a complimentary yoga mat and zen out.You can even travel in style with exclusive (专属的) tour guides, who provide free city tours from certain airports like Singapore, Seoul, Tokyo, and Istanbul. Or take advantage of the free personal shopper during your stay at London’s Heathrow Airport. Check out even more ways to make the most of your long mid-journey stay.The perks don’t stop once you board the plane, either. Some major airlines also offer major flight perks for their passengers. Go and figure them out!5.What part does the first paragraph play in the passage?A.A lead-in. B.A comment.C.A summary. D.A background.6.What does the underlined part in Para. 2 mean?A.Knocking down the bank. B.Borrowing money from the bank. C.Depositing your money. D.Using up your money.7.What can you do in Miami Airport for free?A.Visit the pig.B.Watch movies.C.Enjoy live events.D.Travel with an exclusive tour guide.8.Who are the text most likely intended for?A.Visitors to the USA.B.Airport personnel.C.Airport shopkeepers. D.Airline passengers.Smokers may ignore the health warnings by telling themselves their habit makes them look cool. After all, sex symbols James Dean and Humphrey Bogart were rarely seen without a cigarette. However, the latest evidence shows that smoking actually makes you less attractive to the opposite sex. Wrinkles from smoking a cigarette may be to blame for people judging non-smokers to be better-looking.This was the result of a study asking more than 500 people to pick the most attractive of twins where one smoked and the other did not. Men found female non-smokers the most attractive in two-thirds of cases, while women chose non-smoking men as the most attractive 68 percent of the time.Professor Ian Penton-V oak, a co-author of the study from Bristol University, said, “People assume that smoking causes damage to the skin and appearance, but this is a really neat way of looking at it because these twins are genetically identical, so we can control for genetic factors involved in ageing. Appearance seems to be important to people, especially young people, so we could use these sorts of findings as a basis for future interventions to stop people smoking.”Smoking can speed up the normal ageing, even after only a decade. Nicotine causes narrowing of the blood vessels in the outermost layers of the skin, while the chemicals in tobacco smoke damage collagen and elastin, fibres which give the skin its elasticity (弹性).The wrinkles this causes are added to by facial expressions made when smoking such as pursing the lips when inhaling (吸气) or squinting to keep smoke out of your eyes.9.Why does the author mention James Dean and Humphrey Bogart?A.To persuade smokers to give up smoking.B.To compare them with non-smokers.C.To tell us many people are influenced by them.D.To show understanding and comfort smokers.10.What can we learn from Para. 2 and Para. 3?A.500 twins were surveyed for the study.B.Probably young people pay more attention to their appearance.C.Female non-smokers are more attractive than male ones.D.Professor Ian Penton-V oak is the leading author of the study.11.What is Professor Ian Penton-V oak’s altitude to smoking?A.Disapproving. B.Favorable.C.Unconcerned. D.Cautious.12.What can be inferred from the text?A.Smokers look cooler than non-smokers.B.Smoking may speed up skin’s ageing.C.Smokers look younger than non-smokers.D.Smoking should be banned right away.二、七选五When I was young and foolish I used to think that potential friends were people you liked. You had shared interests. 13.You were interested in what the other had said, or you pretended to be, at least sometimes.14.I realize that friends are people who turn up on time. If you want to be my friend, all it would take is for you to arrive where we agreed and when we agreed. No last-minute texts. No frantic (疯狂的) phone calls complaining that you’re stuck on the bus and the traffic is terrible.15.So it cannot be your everlasting excuse. You can take it into consideration, and set off ten minutes early in case of a total disaster.16.So I have every sympathy with the minister of the Holy Cross Church in Bearsted, Kent, who has started fining brides £ 100 if they turn up late. He says he’s going to add it to the wedding fee and return it afterwards with the marriage certificate if the couple manage to be punctual.17.So cheer for all the brides and grooms who make it to the church on time. I’d happily count any of them as friends.A.And now I know how innocent I was.B.I think what he said is totally nonsense.C.You made each other laugh and enjoyed yourselves.D.Thus, you arrive cm time or, oven better, five minutes early.E.Crowded traffic is a matter happening every clay and everywhere.F.You understood each other and gave the other in need timely help.G.His point is reasonable, though I’m not sure if the way he makes it is wise.三、完形填空Christmas was coming and I decided to buy something for my dad. While chatting with a cashier as I was purchasing a little 18 , some lights, and decorations, he 19 what I would Be doing with this little tree. I explained that it was not for me, but for my dad, 20 he no longer lived at home.The cashier just stopped and looked at me 21 the most kindest look and 22 with me that his grandfather couldn’t live in their hom e either. He said his grandfather was 23 now in a facility for those with Alzheimer’s (阿尔茨海默症). So I shared with him that my dad was on the same 24 . We talked about the difficult 25 that came with this cruel disease, not only for those with the illness, but for their 26 too.

We wished each other Merry Christmas and the 32 possible hopes for our loved ones.On the way home I kept thinking of the kindness he had 33 me with all the items I had purchased. But I was most 34 for the opportunity for us to connect about an 35 we are both going through. I 36 Dad’s tree as soon as I got home. So grateful.

Well, we certainly know from 39.(evident) in our own sleep center and that of many other scientists that naps can give you benefits for both your brain 40.your body. Bui naps can actually be 41.double-edged sword because while we’re awake during the day, we’re building up sleepiness or sleep pressure. So that when you try to fall asleep at night, you’ll fall asleep quickly.42.is a basic guarantee for a good sleep. And when we sleep, we actually release that sleepiness, almost like a valve (阀门), on a pressure cooker, so that we wake up the next morning feeling 43.(refresh).So if you take a nap during the day, especially if you take it too late in the afternoon, you will actually release some of that sleepiness and it will make it much 44.(hard) to fall asleep and stay asleep 45.(sound) throughout the night. So the advice is if you don’t struggle 46.your sleep and you can nap regularly, then naps are just fine.But if you do have trouble 47.(fall) asleep at night, then you should avoid naps and try and build up that healthy sleepiness in the evening.五、短文改错48.假定英语课上老师要求同桌之间交换修改作文,请你修改你同桌写的以下作文,文中共有10处语言错误,每句中最多有两处,每处错误仅涉及一个单词的增加、删除或修改。

It was a touching act of kindness, but, as it turned out, not a random one. T he cake had been paid for by a lady known simply as “McKenna’s mum” -as part of a gesture she had been making for a while, and for a heartbreaking reason.While Madison is set to celebrate turning 11, McKenna Jodell Fox would have turnedten on the same day. McKenna was only nine months old in 2008, when she was crushed by a falling TV set as her family prepared to move house.It’s a painful occasion for her mum, but one she has transformed into something positive. The cake she bought was accompanied by a card which read as follows: “Dear Birthday Girl Family,In honour of my daughter’s 10th birthday I have chosen your birthday cake to pay for.Each year I do this random act of kindness because I am unable to buy my daughter a cake of her own.Today is her big double digit birthday. Please enjoy your day.”By Kyle’s own admission, the whole family was left speechless. “We just want to say thank you to McKenna’s mom,” he wrote, “and wish McKenna a happy birthday. There’s still good in this world.”24. Who died according to the passage?A. Kyle Jauregui.B. Madison.C. McKenna Jodell Fox.D. McKenna’s mum.25. What do we know about the birthday cake?A.

A Painful AccidentB. A Family Left SpeechlessC. One Birthday Cake for Two GirlsD. A World Full of SurprisesCUh-oh-you’re stuck with a long mid-journey stay or an insane flight delay. Whatto do? Spending hours in an airport can make any person who travels by plane a little annoyed. But before you splurge (挥霍) at the bar or duty-free shops, you might want to ask about your airport’s perks (特权).There are a lot of things you can do in the airport without breaking the bank.To reduce your annoyance and save your wallet, VIVA Lifestyle and Travel has compiled a list of all of the best airport perks. Make sure you’re not making these mistakes on your next flight, too.Some airports, such as Portland International Airport in Oregon, San Francisco International Airport in California, or Minneapolis-St. Paul International Airport, offer free movies to waiting passengers. Others have free museums and live events, including San Francisco, Miami, Albany, Minneapolis, Portland, and St. Louis.Looking to relax after a stressful trip?

If you’re flying through San Francisco, Chicago, Miami, or Dallas Fort Worth, borrow a complimentary yoga mat and zen out.You can even travel in style with exclusive (专属的) tour guides, who provide free city tours from certain airports like Singapore, Seoul, Tokyo, and Istanbul.

Airline passengers.DSmokers may ignore the health warnings by telling themselves their habit makes them look cool. After all, sex symbols James Dean and Humphrey Bogart were rarely seen without a cigarette. However, the latest evidence shows that smoking actually makes you less attractive to the opposite sex. Wrinkles from smoking a cigarette may be to blame for people judging non-smokers to be better-looking.This was the result of a study asking more than 500 people to pick the most attractive of twins where one smoked and the other did not. Men found female non-smokers the most attractive in two-thirds of cases, while women chose non-smoking men as the most attractive 68 percent of the time.Professor Ian Penton-Voak, a co-author of the study from Bristol University, said, “People assume that smoking causes damage to the skin and appearance, but this is a really neat way of looking at it because these twins are genetically identical, so we can control for genetic factors involved in ageing. Appearance seems to be important to people, especially young people, so we could use these sorts of findings as a basis for future interventions to stop people smoking.”Smoking can speed up the normal ageing, even after only a decade. Nicotine causes narrowing of the blood vessels in the outermost layers of the skin, while the chemicals in tobacco smoke damage collagen and elastin, fibres which give the skin its elasticity (弹性).The wrinkles this causes are added to by facial expressions made when smoking such as pursing the lips when inhaling (吸气) or squinting to keep smoke out of your eyes.32. Why does the author mention James Dean and Humphrey Bogart?A. To persuade smokers to give up smoking.B. To compare them with non-smokers.C. To tell us many people are influenced by them.D. To show understanding and comfort smokers.33. What can we learn from Para. 2 and Para. 3?A. 500 twins were surveyed for the study.B. Probably young people pay more attention to their appearance.C. Female non-smokers are more attractive than male ones.D. Professor Ian Penton-Voak is the leading author of the study.34. What is Professor Ian Penton-Voak’s altitude to smoking?A. Disapproving.B. Favorable.C. Unconcerned.D. Cautious.35. What can be inferred from the text?A. Smokers look cooler than non-smokers.B. Smoking may speed up skin’s ageing.C. Smokers look younger than non-smokers.D. Smoking should be banned right away.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
