D 【解析】D 解析:因为有10正品,2个次品,所以任意抽取3个,有3中情况:3个都是正品;2个正品,1个次品;1个正品,2个次品.只有D包含了这3种情况.2. B3. A 【解析】设y=fʹ(x)的图象与工轴的交点(除原点外)依次为x1、x2、x3,则当x∈(a,x1)时,fʹ(x)>0,函数yʹ=(x)是增函数;当x∈(x1,x2)时,fʹ(x)<0,函数y=f(x)是减函数;当x∈(x2,x3)时,fʹ(x)≥0,函数y=f(x)是增函数;当x∈(x3,b)时,fʹ(x)<0,函数y=f(x)是减函数.所以当x=x2时,取得极小值,再无其他极小值点.4. A5. C6解:当|PQ|=6时,圆心到线段PQ的距离d=,此时M位于半径是4的圆上,∴若|PQ|<6,则PQ中点组成的区域为M为半径为4的圆与半径为5的圆组成的圆环,即16<x2+y2<25,PQ中点组成的区域为M如图所示,那么在C内部任取一点落在M内的概率为,故选:B.7. C 【解析】因为函数f(x)=x−tsinx(0<t≤1),所以函数fʹ(x)=1−tcosx≥0恒成立,故函数f(x)为增函数,又由f(−x)=−x−tsin(−x)=−(x−tsinx)=−f(x),故函数 f (x ) 为奇函数, 若 f (log 2m )>−f (−1)=f (1), 则 log 2m >1, 解得:m ∈(2,+∞) . 8. D9. C【解析】提示:设 OQ ⃗⃗⃗⃗⃗⃗ =λOP ⃗⃗⃗⃗⃗ =(λ,λ,2λ),则 QA ⃗⃗⃗⃗⃗ =OA ⃗⃗⃗⃗⃗ −OQ⃗⃗⃗⃗⃗⃗ =(1−λ,2−λ,3−2λ),QB ⃗⃗⃗⃗⃗ =OB ⃗⃗⃗⃗⃗ −OQ ⃗⃗⃗⃗⃗⃗ =(2−λ,1−λ,2−2λ),QA ⃗⃗⃗⃗⃗ ⋅QB ⃗⃗⃗⃗⃗ =6(λ−43)2−23,当 λ=43时,QA ⃗⃗⃗⃗⃗ ⋅QB ⃗⃗⃗⃗⃗ 取得最小值. 10. B【解析】对于①,若 am 2<bm 2,可知,m 2>0,则 a <b ,故正确;对于②,因为变量 x 和 y 满足关系 y =−0.1x +1,一次项系数为 −0.1<0,所以 x 与 y 负相关;变量 y 与 z 正相关,设 y =kz (k >0),所以 kz =−0.1x +1,得到 z =−0.1kx +1k ,一次项系数小于 0,所以 z 与 x 负相关,故正确;对于③,若 m ⊥n ,m ⊥α,n ∥β,则 α,β 的位置关系不定,故错;对于④,当 m =0 时,直线 (m +3)x +my −2=0 与直线 mx −6y +5=0 也互相垂直,故错.11. C 设 M (x 1,y 1),N (x 2,y 2),则切点分别为 M ,N 的切线方程为x 1x 4−y 1y 12=1,x 2x4−y 2y 12=1.因为点Q(1,t)在两条切线上,所以x14−y1t12=1,x24−y2t12=1.所以M,N两点均在直线x 4−ty12=1上,即直线MN的方程为x4−ty12=1,显然直线过点(4,0).12.D 解:令g(x)=f(x)﹣,则g′(x)=f′(x)>0,∴g(x)在定义域R上是增函数,且g(1)=f(1)=0,∴g(2cos x)=f(2cos x)﹣cos x=f(2cos x)﹣cos x,令2cos x>1,则g(2cos x)>0,即f(2cos x)>+cos x,又∵x∈[﹣,],且2cos x >1∴x∈(﹣,),故选:D.第二部分13.﹣4 解:因为点P,Q的横坐标分别为4,﹣2,代入抛物线方程得P,Q的纵坐标分别为8,2.由x2=2y,则y=x2,所以y′=x,过点P,Q的抛物线的切线的斜率分别为4,﹣2,所以过点P,Q的抛物线的切线方程分别为y=4x﹣8,y=﹣2x﹣2 联立方程组解得x=1,y =﹣4故点A的纵坐标为﹣4.故答案为:﹣4.14. √3【解析】因为z=m+3i1+mi =(m+3i)(1−mi)1+m2=4m1+m2+3−m21+m2i,且z=z,所以3−m2=0,解得m=±√3.又因为m>0,所以m=√3.15. [−1,12]16. (2,+∞)【解析】设直线l:y=12x+m,(m>0),A(x1,y1),B(x2,y2),则:{y =12x +m y 2=2px得:x 2+(4m −8p )x +4m 2=0.Δ=64p 2−64mp >0所以 p >m >0 . x 1+x 2=8p −4m , x 1x 2=4m 2 . k 1+k 2=y 1x 1+y2x 2=x 1x 2+m (x 1+x 2)x 1x 2=2p m>2 .第三部分17. (1) 若从这 7 天随机抽取两天,有 C 72=21 种情况,两天人数均少于 10,有 3 种情况,所以至少有 1 天参加抽奖人数超过 10 的概率为 1−321=67.(2) x =4,y =11,b ̀=∑x i ni=1y i −nx y ∑x i 2n i=1−nx2=364−7×4×11140−7×42=2,à=y −b ̀x =11−4×2=3, 所以 ỳ=2x +3,所以估计若该活动持续 10 天,共有 77+19+21+23=140 名顾客参加抽奖.18.(I )证明:∵AA 1C 1C 是正方形,∴AA 1⊥AC .又∵平面ABC ⊥平面AA 1C 1C ,平面ABC ∩平面AA 1C 1C =AC ,∴AA 1⊥平面ABC . (II )解:由AC =4,BC =5,AB =3.∴AC 2+AB 2=BC 2,∴AB ⊥AC .建立如图所示的空间直角坐标系,则A 1(0,0,4),B (0,3,0),B 1(0,3,4),C 1(4,0,4),∴,,. 设平面A 1BC 1的法向量为,平面B 1BC 1的法向量为=(x 2,y 2,z 2). 则,令y 1=4,解得x 1=0,z 1=3,∴.,令x2=3,解得y2=4,z2=0,∴.===.∴二面角A1﹣BC1﹣B1的余弦值为.(III)设点D的竖坐标为t,(0<t<4),在平面BCC1B1中作DE⊥BC于E,可得D ,∴=,=(0,3,﹣4),∵,∴,∴,解得t=.∴.19.解:(1)F是抛物线C:y2=2px(p>0)的焦点(,0),根据题意,点Q在FO的垂直平分线上,所以点Q到准线x=﹣的距离为,所以C:y2=4x.(2)设,①设直线l:x=my﹣1代入到y2=4x中得y2﹣4my+4=0,所以y1+y2=4m,y1y2=4,②由①②可得4m2==λ++2,由2≤λ≤3可得y=λ++2递增,即有4m2∈[,],又AB中点(2m2﹣1,2m),所以直线AB的垂直平分线的方程为y﹣2m=﹣m(x﹣2m2+1),令y=0,可得.20.解:(1)∵f′(x)=,(x>0),∴△=4﹣8a=4(1﹣2a),①a≥时,有△≤0,∴f′(x)>0在(0,+∞)上恒成立,∴f(x)在(0,+∞)递增,②0<a<时,有△>0,令f′(x)=0,解得:x1=(x1>0),x2=,令f′(x)>0,解得:0<x<或x>,令f′(x)<0,解得:<x<,∴f(x)在(0,),(,+∞)递增,在(,)递减;③a≤0时,有△>0,且②中的x1=≤0,令f′(x)>0,解得:x>,令f′(x)<0,解得:0<x<,∴f(x)在(0,)递减,在(,+∞)递增;(2)∵x2为极值点,∴f′(x2)=0,即2﹣2x2+a=0,解得:a=2x2﹣2,由(1)中②可知<x2<1,∴f(x2)=﹣2x2+1+(2x2﹣2)lnx2,(<x2<1),令g(t)=t2﹣2t+1+(2t﹣2t2)lnt,(<t<1),∴g′(t)=2(1﹣2t)lnt,当t∈(,1)时,g′(t)>0,∴g(t)在(,1)上递增,∴g(t)>g()=,∴f(x2)=g(x2)>.21. (1) 由题意得,b 2=1,c =1.所以 a 2=b 2+c 2=2.所以椭圆 C 的方程为 x 22+y 2=1.(2) 设 P (x 1,y 1),Q (x 2,y 2),则直线 AP 的方程为 y =y 1−1x 1x +1.令 y =0,得点 M 的横坐标 x M =−x 1y 1−1.又 y 1=kx 1+t ,从而 ∣OM ∣=∣x M ∣=∣x 1kx 1+t−1∣.同理,∣ON ∣=x 2kx 2+t−1.由 {y =kx +t,x 22+y 2=1,得 (1+2k 2)x 2+4ktx +2t 2−2=0.则 x 1+x 2=−4kt1+2k 2,x 1x 2=2t 2−21+2k 2.所以∣OM ∣⋅∣ON ∣=∣x 1kx 1+t−1∣⋅∣x 2kx 2+t−1∣=∣x 1x 2k 2x 1x 2+k (t−1)(x 1+x 2)+(t−1)2∣=∣2t 2−21+2k 2k 2⋅2t 2−21+2k 2+k (t−1)⋅(−4kt1+2k 2)+(t−1)2∣=2∣1+t1−t ∣.又 ∣OM ∣⋅∣ON ∣=2,所以 2∣1+t 1−t∣=2.解得 t =0,所以直线 l 经过定点 (0,0).22. (1) F (x )=e x −2x −b ,则 F ʹ(x )=e x −2,令 F ʹ(x )=e x −2>0,得 x >ln2, 所以 F (x ) 在 (ln2,+∞) 上单调递增.令 F ʹ(x )=e x −2<0,得 x <ln2, 所以 F (x ) 在 (−∞,ln2) 上单调递减.(2) 因为 f ʹ(x )=e x +2x −1,所以 f ʹ(0)=0,所以 l 的方程为 y =1.依题意,−a2=1,c =1.于是 l 与抛物线 g (x )=x 2−2x +b 切于点 (1,1),由 12−2+b =1 得 b =2.所以 a =−2,b =2,c =1.(3) 设 ℎ(x )=f (x )−g (x )=e x −(a +1)x −b ,则 ℎ(x )≥0 恒成立.易得 ℎʹ(x )=e x −(a +1).(1)当 a +1≤0 时,因为 ℎʹ(x )>0,所以此时 ℎ(x ) 在 (−∞,+∞) 上单调递增.①若a+1=0,则当b≤0时满足条件,此时a+b≤−1;,此时ℎ(x0)=e x0−(a+1)x0−b<1−②若a+1<0,取x0<0且x0<1−ba+1(a+1)1−b−b=0,a+1所以ℎ(x)≥0不恒成立,不满足条件;(2)当a+1>0时,令ℎʹ(x)=0,得x=ln(a+1).由ℎʹ(x)>0,得x>ln(a+1);由ℎʹ(x)<0,得x<ln(a+1).所以ℎ(x)在(−∞,ln(a+1))上单调递减,在(ln(a+1),+∞)上单调递增.要使得“ℎ(x)=e x−(a+1)x−b≥0恒成立”,必须有“当x=ln(a+1)时,ℎ(x)min= (a+1)−(a+1)ln(a+1)−b≥0”成立.所以b≤(a+1)−(a+1)ln(a+1).则a+b≤2(a+1)−(a+1)ln(a+1)−1.令G(x)=2x−xlnx−1,x>0,则Gʹ(x)= 1−lnx.令Gʹ(x)=0,得x=e.由Gʹ(x)>0,得0<x<e;由Gʹ(x)<0,得x>e.所以G(x)在(0,e)上单调递增,在(e,+∞)上单调递减,所以,当x=e时,G(x)max= e−1.从而,当a=e−1,b=0时,a+b的最大值为e−1.综上,a+b的最大值为e−1.。

AOne of the latest trends(趋势)in American Childcare is Chinese au pairs. Au Pair in Stamford, Conn., for example, has got increasing numbers of request for Chinese au pairs from zero to around 4, 000 since 2004. And that’s true all across the country.“I thought it would be very useful for him to learn Chinese at an early age,” Joseph Stocke, the managing director of a company, says of his 2-year old son. “I would at least like to give him the chance to use the language in the future.” After only six months of being cared by 25-year-old woman from China, the boy can already understand basic Chinese daily expressions, his dad says.Li Drake, a Chinese native raising two children in Minnesota with an American husband, had another reason for looking for an au pair from China: She didn’t want her children to miss out on their roots. “Because I am Chinese, my husband and I wanted the children to keep exposed to (接触) the language and culture. ” she says.“Staying with a native speaker is better for children than simply sitting in a classroom, ” says Suzanne Flynn, a professor in language education of Children. “But parents must unders tand that just one year with au pair is unlikely to produce wonders. Complete mastery demands continued learning until the age of 10 or 12. ”The popularity if au pairs from China has been strengthened by the increasing numbers of American parents who want their children to learn Chinese. It is expected that American demand for au pairs will continue to rise in the next few years.1.What does the term “au pair” in the text mean?A.A mother raising her children on her own.B.A child learning a foreign language at homeC.A professor in language education of childrenD.A young foreign woman taking care of children.2.Li Drake has her children study Chinese because she wants them .A.to live in China some dayB.to speak the language at homeC.to catch up wit other childrenD.to learn about the Chinese culture3.What can we infer from the text?A.Learning Chinese is becoming popular In A merica,cated women do better in looking after childrenC.Chinese au pairs need to improve their English skills.D.Children can learn a foreign language well in six months.BOctober 15th is Global Handwashing Day. Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap.Experts say people around the world wash their hands but very few use soap at so-called extremely important moments. These include after using the toilet, after cleaning a baby and before touching food.Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. The goal, they say, is to create a culture of handwashing with soap. The organizers say all soaps are equally effective at removing disease-causing germs(细菌). They say the correct way to wash is to wet your hands with a smallamount of water and cover them with soap. Rub it into all areas, including under the fingernails. Then, wash well under running water. Finally, dry your hands with a clean cloth.The Partnership says soap is important because it increases the time that people spend washing. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell, which increases the chances that people will wash again.It also says that washing hands with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea( 痢疾), which is the second leading cause of child deaths, killing more than one and a half million children a year, by almost half.Parents and caretakers play an important role in teaching children to wash their hands. Handwashing can become a lifelong healthy habit if you start teaching it at an early age. Building handwashing skills takes time. At first, your child will need regular reminders of how and when to wash hands. It is especially important to remind children to wash their hands after using the bathroom, before eating, after touching pets, after playing outside, and after coughing, sneezing, or blowing their nose. But once handwashing becomes a habit and a regular part of your child’s day, they will practice it throughout their lives. You can find ways to make it fun, like making up your own handwashing song or turning it into a game.4.What does the author intend to tell us in the passage?A.To keep healthy by washing hands.B.To wash hands with soap.C.To take action to wash hands.D.To wash hands often.5.Which of the following is the right way to wash hands?a . Washing hands well under running water .b.Covering hands with soap.c.Drying hands.d.Rubbing hands with soap.e.Wetting hands.A.a-c-b-e-dB.e-d-a-b-cC.a-c-b-d-eD.e-b-d-a-c6.According to the paragraph 5, diarrhea is a diseaseA.kills half of the kids in the developing countries a yearB.causes the greatest number of child deathsC.can be prevented to some degree by washing hands with soapD.can't be cured without washing hands7.According to the last paragraph, which of the following is not true?Parental help is a key factor to cultivate the children’s habit of handwashing.Kids can develop the habit of handwashing automatically.Handwashing for kids can be fun.Handwashing correctly is not easy for kids.CTo some, it's a dream job—eating delicious meals for free and then writing about them. But for some food critics, their eyes aren't the only thing that gets wide with yet another feast.Karen Fernau, a food writer for The Arizona Republic, said when she first started her job, she began to gain weight. "I always looked forward to lunch before this job, then all of a sudden lunch was all day every day," she says. Nine years later, keeping her weight steady and her health intact (完好⽂损的) is a daily battle. If she knows she will be going to a tasting at a bakery or eating a four-course meal, she usually eats fruits or salads throughout the day. Now she is always keeping track of what's in the food she eats and she says most people don't even look at or consider it.At one tasting task alone, she says, upward of 1,000 calories is often added to her day. That's about half of the recommended total calories per day for the average adult.But even though she's thought of a special eating method, Fernau says sticking to it is a daily battle. And food editors, writers and critics across the country couldn't agree more. "When I'm at home or not eating for work, it's healthy food to the extreme," says Phil Vettle, who's been a restaurant critic for the Chicago Tribune for 19 years.Vettle, who eats dinner at four restaurants each week, says unlike most professions, he has no right to choose. "If I'm going out to eat, I can't choose the healthiest thing on the menu. I have to eat when they're bringing me.” While Vettle exercises when he can, Joe Yonan, a food editor at The Washington Post, has strengthened his exercise habits since he started the job two years ago. Yonan says he realized early on that he was gaining weight and immediately hired a personal trainer to meet with three times a week, on top of his cardio ( 有氧的) training three to five times a week.Still, it's a struggle that many Americans might envy. After all, it's one thing to get your calories fromlobster(龙虾)tails or a delicate(可⽂的)chocolate cookie and quite another to get them from sodas and fast-food burgers.8.What does the underlined sentence mean in Para.1?A.The food critics are always impressed by the delicious food in the restaurant.B.The food critics are shocked to learn they have to have one more feast.C.There is a wide variety of choices for the food critics to choose from.D.The food critics eat delicious food, which also tends to result in gaining weight.9.What can we learn about the job of being a food critic?A.They enjoy free and delicious dishes and make comments on them.B.They only work for local magazines and newspapers .C.Once they become food critics, they tend to stay in the job.D.Their excellent sense of taste makes them qualified for the job.10.What can we infer from the last paragraph?A.No matter whether the food is expensive or not, the gaining of calories is the same.B.The calories that lobster tails and chocolate cookies contain are less harmful.C.Americans envy those food critics since they enjoy delicate and tasty food.D.Everybody should take the calories in their food carefully.11 . What's the main idea of the passage ?A.A job offering free meals may not be as desirable as it sounds to be.B.Dishes in the restaurant usually contain too many calories.C.Eating fruits and vegetables every day is the best way to lose weight.D.Food writers work hard to maintain their health and weight.DIf you’ve done a lot of traveling, you’ve probably noticed that the bookstores at airports all look pretty similar. They’ve all got familiar logos, the walls of inviting plane snacks, and the towers of new hardcover books. Chances are you’ve wanted to grab one of those books for the plane ride and, if you’ve got a long flight. However, those hardcover books are a little pricey. Is it worth it to buy, for the sake of relieving the midair boredom?Yes it is—because of a cool program that these bookstores have in place. These similar airport stores are all owned by the company Paradies Lagardère, and all of those stores take part in what’s called the “Read and Return program.” It’s exactly what it sounds like. Whenever you buy one of those books, you’ve got six months to finish it and bring it back to the same, or another, Paradies Lagardère location. When you do that, you get half your money for the original purchase back. Awesome, right?!So, if you’re going on a trip, buy that book you’ve been dying to read, and read it on the plane or over the course of the trip. When you go back to the airport for the return trip, bring the book back with you and get half the money back. That money’s now yours again, to use however you want. Your boredom on the flight back is cured. And it gets better: the book you gave back will be re-sold for half price!There are two things you do need to make sure of. You have to bring back the receipt to get your money back, and I just use it as a bookmark! Also, the book needs to be in decent condition. But if it’s not, they’ll still take the book back, and donate it! But other than that, this program couldn’t be easier. In a way, it’s like a buy- one-get-one-half-off deal for books. Or get two books for the price of one-and-a-half.12.Why do all the bookstores at the airports look the same?A.Because they all have familiar logos and delicious snakes.B.Because they are all located at airports.C.Because they sell almost the same books.D.Because they belong to a parent company.13.What is the best of way of keeping the receipt according to the author?A.Putting it in your wallet.B. Using it as a bookmarkC. Attach it to your book.D. Leaving it to the cashier.14.Which of the following is true?A.You can't get your half money back if the book is stained with coffee.B.Reading books is a great way to improve yourself according to the passage.C.If you brought a book for 20$ and returned it, the next person would get 10$ back when returning it.D.If you purchased a book at the airport of Los Angles, you could return it at the airport of New York.15.What is the author's attitude toward the program?Positive B. Critical C. Neutral D. Indifferent第⾼节(共5⾼题,每⾼题2分,满分10分)根据短⾼内容,从短⾼后的选项中选出能填⾼空⾼处的最佳选项,选项中有两项为多余选项。

①张荣在《故宫经典》里说:“文房清供是中国传统文房辅助用具的一种雅称,也称文房杂器,又因多由精美的工艺造型和极具观赏性的器物组成而被称为文玩。

”他直接将“文玩”界定为“美”的“文房”“器物”。

传统意义上的“文玩”当是狭义的“文玩”,今天的“文玩”则是就广义来说的,今之“文玩”已成为“为生活增添赏玩之趣的物件”。

②刘岳曾言,“从字面来看,‘文玩’二字中‘文’者大约可拆分出三层意思:第一层指活动主体为文人士大夫;第二层指活动场所为文房;第三层指对象需文雅,涉及审美价值的判断;而‘玩’字既可作名词指玩物,也有动词玩赏、玩味之意。

故而‘文玩’不同于声色犬马的物质享受和低层次娱乐,而是可以增长知识、陶冶性情的艺术欣赏对象。

”他比较精准地揭示并阐发了”文玩”的审美本质。

③步入新时代,随着国民经济发展和人民生活水平的提高,“文玩”发展环境发生巨变,公众对“文玩”的兴趣日渐浓厚、需求日益增长,“文玩”已逐步深入大众生活,“文玩”把玩主体发生更迭,由传统文人拓展为广大民众;“文玩”的品类、形态及其收藏、交易也均在发生深刻变迁,实用价值也逐渐被文化和把玩价值取代,“文玩”也随之实现了对自身“物”的属性的超越而演化为注入了新时代意蕴的文化符号,但是,它的审美本质却从未改变。

④“文玩”之要即对雅致器物的赏玩。

任何一件“文玩”都应是一件完整的传统工艺作品,必须同时兼具内容、形式、技艺、材料“四美”,并在此基础上完美承载和体现中华优秀传统哲学美学思想。

“文玩”代表着玩家、藏家乃至社会、时代的审美意识,是尊崇传统、崇尚自然、礼敬人文的态度,是内省自觉、归属认同、渴求创新的符号,是悦心娱人、感染世人、引领时尚的欣赏。

⑤“文玩”之“文”,蕴涵着崇文尚雅的核心意识。

PaymentBLas Vegascity inNevadais built in a desert. The city may be known to the outside world for its partying. But officials have found that there are 21 square kilometers of useless grass. The grass is never laid on, played on or even stepped on. The grass is only there to look nice.Now, the city is asking theNevadastate legislature to ban useless grass. It is trying to become the first place inAmericato ban that kind of grass often seen between streets, in housing developments and in office parks.It is estimated that useless grass makes up 40% of all the grass inLas Vegasand it needs a lot of water to survive. Grass needs four times more water than dry climate plants like cactus. By tearing out the grass, the city could reduce yearly water usage by 15%.In 2003, the Southern Nevada Water Authority banned developers from planting grass in front of new homes. It also offered homeowners $ 30 for each square meter of grass they tear out. But fewer people are now using the program. Water usage has increased in southernNevadaby 9% since 2019. And last year,Las Vegaswent a record 240 days without major rainfall. The Colorado River provides much ofNevada's drinking water. The river could lose more water as climate change affects it.Water officials in other dry cities said water usage needs to be reduced. But they fear the reaction to reforms like the ones inLas Vegasif their communities do not accept them.

A Dutch company called Mars One will soon advertise for people interested in colonizing (开拓) Mars. Ifyou have all the necessary skills, you could be one of the first colonists. Are you ready for the challenge?You won’t have to pay for the mission to Mars. Mars One has already received money from some donors and is hoping to get more from TV viewers who will become interested in the show where all applicants have a debate for the rare chances.The main responsibility of the first colonists is to create an artificial environment on Mars where there is no air to breathe and no land to farm. Scientists know it’s quite possible because something similar has already been done inAntarctica.Another problem is that space travel to Mars takes nearly a year to get to Mars and the colonists will live the rest of their lives there. When a human lives in an environment without gravity or with low gravity for a long time, the systems in the body weaken. Luckily, spinning (旋转) the spaceship can create artificial gravity, and artificial gravity can ease these problems. It will also be difficult for Mars colonists to be far from home, living in small spaces, and seeing the same people over and over. Colonists with depression could put the mission in danger. Fortunately, a few years ago, a joint Russian and European project called the Mars500 Mission studied people’s reactions in a Mars-like environment. It is viewed as a great success because scientists were able to see howpeople handle emotional and physical stresses.Recent studies show that seven percent of people would want to go on such an adventure.Mars One will soon start accepting its first colonists. Are you interested?8. What do we know about the applicants to Mars from the first two paragraphs?A. They will land on Mars in 2023.B. They can get money from donors.C. They will compete in a TV show.D. They do not need special skills.9. What will the first colonists do to solve the basic living problems on Mars?A. Create earth-like conditions.B. Build labs inAntarctica.C. Spin the spaceship.D. Start the Mars500Mission.10. What can the life of the first colonists be like according to the passage?A. Difficult and dangerous.B. Different but adaptable.C. Challenging and unbearable .D. Acceptable but depressing.11. What’s the best title for the text?A. Mars: our final destination?B. Ready to be Mars’ colonists?C. Space travel: a thrilling adventure?D. Are you a qualified Mars astronaut?DSince I was born and brought up in a rural town, I have a great interest in nature. Using the chance of studying abroad in my second year at college, I decided to go toCanadajust because I wanted to see the beautiful phenomena there So after I finished the study program, I went toYellowknifein theNorthwest Territories.I clearly remember the sixth night inYellowknife. Suddenly my host mother came to my room around 8 p.m. and told me to change clothes and go outside quickly carrying her camera.The northern lights were flickering (闪烁) in the sky! I was shocked and just stood there with my mouth open.I forgot to take pictures of the mysterious lights.Since that night, whenever it was sunny, I went outside at night and looked at the sky. It was so cold that I lost all feeling in myhands and feet.As I took pictures of the northern lights, I came to find a characteristic movement of the lights. They first appear in the north part of the sky and then they gradually come down to the south part of the sky. After that, suddenly, they come in the middle of the north and south only for a while, which is the time when the best northern lights can be seen. Since it is only a few seconds for the northern lights to come down to the middle of the sky, it is very hard to get good pictures.The stronger the sun acts, the better and stronger the northern lights flicker in the sky. That’s because they come about from the collisions (碰撞) between atmospheric gases and the solar wind. Much more solar wind comes to the earth when the sun is active, whichleads to the best northern lights. And the color1 s of the northern lights depend on the height of the collisions and the kinds of gases.12. Why did the host mother ask the author to go out?A. She wanted to take a picture of him.B. She wanted to take a walk with him.C. She wanted to tell him something important.D. She wanted him to see the northern lights.13. The author forgot to take pictures after going out because ______.A. the host mother didn’t remind him to take the cameraB. he was shocked by the wonderful sightC. the lights flickering in the sky disappeared too soonD. he lost all feeling in his hands and feet14. When is the best time to see the northern lights?A. When they appear in the north part of the sky.B. When they come down to the south part of the sky.C. When they are between the north and south.D. When they rise in the east part of the sky.15. What does the last paragraph mainly tell us?A. Waysto take good pictures.B. The relationship between the sun and the northern lights.C.The color1 s of the northern lights.D. The time of the best northern lights.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
