高一习题 生物单元质量检测10
单元质量检测(十)第五章基因突变和其它变异第六章从杂交育种到基因工程(时间:90分钟)一、选择题(共60分)1.人类常染色体上β珠蛋白基因(A+)既有显性突变(A)又有隐性突变(a),突变均可导致地中海贫血。
一对皆患地中海贫血的夫妻生下了一个正常的孩子,这对夫妻可能() A.都是纯合子(体)B.都是杂合子(体)C.都不携带显性突变基因D.都携带隐性突变基因解析:由题意可知,A对A+为显性,A+对a为显性,aa和AA+为患病,A+A+和A+a 为正常,所以一对患病夫妇生下了一个正常的孩子,父母很可能都是AA+。
答案:B2.下列有关基因重组的说法正确的是() A.基因重组可以产生多对等位基因B.发生在生物体内的基因重组都能遗传给后代C.基因重组所产生的新基因型不一定会表达为新的表现型D.基因重组会改变基因中的遗传信息解析:基因重组属于基因的重新组合,不会改变基因内部的碱基序列,不可能产生新的基因,基因中的遗传信息也不会改变。
生物体内经过基因重组所产生的配子不一定能够形成合子,所以不一定能够传递给后代。
基因重组能产生新基因型的配子,不同的配子形成合子的表现型可能是与原有个体的表现型相同。
答案:C3.在减数第一次分裂间期,因某些原因使果蝇Ⅱ号染色体上的DNA分子缺失了一个基因,这种变异属于() A.染色体变异B.基因重组C.基因突变D.基因重组或基因突变解析:DNA分子缺失了一个基因,涉及基因数目的改变,属于染色体结构的变异;而基因突变是DNA分子中碱基对的增添、缺失或替换,导致基因结构的改变。
答案:A4.细胞的有丝分裂与减数分裂都可能产生可遗传的变异,其中仅发生在减数分裂过程的变异是() A.染色体不分离或不能移向两极,导致染色体数目变异B.非同源染色体自由组合,导致基因重组C.染色体复制时受诱变因素影响,导致基因突变D.非同源染色体某片段移接,导致染色体结构变异解析:染色体移向两极的现象在两种分裂方式中都有出现。

fails entirely once heor she starts to push a shopping cart (购物手推车).One of the first things customers forget is how to count.There is no other way to explain how so many people get in their express line, which is clearly marked 15 items or less, with 20, 25 or even a cart load of items.Customers also forget why they came to the store in the first place.Just as I finish ringing up an order, a customer will say,“ Oops, I forgot to pick up a fresh loaf of bread.I hope you don't mind waiting while I go to get it.”Five minutes later,he's back with the bread, a bottle of milk, and three rolls of paper towels.What is stranger is that customers also seem to forget that they have to pay for their groceries.Instead of writing a check or looking for a credit card while I am ringing up the groceries, a customer will wait until I announce the total.Then, in surprise, she says,“ Oh no, what did I do with my check book?” After 5 minutes of digging through her purse, she borrows my pen because she's forgotten hers.But I have to tolerate customers because they pay my salary, and that's something I can't afford to forget.46.What does the author say about his customers?A.They can not count numbers.B.They sometimes jump the queue.C.They don't know how to express themselves.D.They behave as if their memories have totally failed.47.According to the text, who are supposed to be in the express line?A.Customers with nothing purchased.B.Customers with no more than 15 items.C.Customers with items between 15 and 25.D.Customers with 25 or even a cart load of items.48.When customers arrive at the checkout counter, they________.A.find their pens lostB.go back and get more itemsC.can not wait to pay for their groceriesD.prefer paying by check to paying with a credit card49.We can infer from the text that________.A.business in the grocery store runs wellB.the author finds his present job full of funC.the author's parttime job calls for patienceD.customers go to grocery stores without planningBFlappy Bird is flapping (拍打) its wings no more.The popular game for mobile equipment was removed from online stores on Sunday by its Vietnamese creator, who said its fame “destroys my simple life”.Dong Nguyen, who created the game in just two to three days, was making as much as DS| 50,000 a day from the game's advertising income.In several Twitter posts, he said the game's removal was not due to legal issues (问题) and that he may make a followup.Mr Nguyen, who describes himself as an “enthusiastic independent game maker”,also said on the microblogging site that he would not sell Flappy Bird but he would still make games.Flappy Bird has been downloaded more than 50 million times,making it this year's most popular mobile game so far . Coming out in May 2013, the game was free to download and required players to tap the screen to keep the bird in flight.In spite of its simple graphs, Flappy Bird was an extremely difficult game since many users could only keep the bird in the air for a few seconds before it hits an obstacle (障碍物) and falls.After Mr Nguyen took the game down, many fans turned to social media to ask for its return.The game is no longer available through online stores, but it still works on phones that had previously downloaded it.However, some fans expressed their relief that the game was gone.One user described Flappy Bird as “an addictive game that everyone hate s to love”, while another said,“ I think it's for the best, and for the best of all the brokendown phones out there.”50.Dong Nguyen took Flappy Bird down because________.A.it was against the lawB.it was easily destroyedC.it disturbed his normal lifeD.it could break down phones51.What can we learn about Dong Nguyen from the text?A.He is addicted to playing games.B.He likes to make games by himself.C.He earned a lot by selling Flappy Bird.D.He rose to fame after removing his game.52.What were the users' reactions to Dong Nguyen's removing the game?A.Some felt happy and relaxed.B.Some got so angry that they accused him.C.Some regretted they couldn't keep the bird in flight.D.Some asked social media to help develop another game.53.What would be the best title for this text?A.Flappy Bird — A Mobile GameB.Flappy Bird — A Computer GameC.Dong Nguyen — A Game CreatorD.Dong Nguyen — A Talented PersonC(安徽高考)Personal Robot Make your parents and teachers happy!Are you having problems finishing your homework on time?

B.In a company brochure.C.On a teenage website. D.In a college newspaper.DMore and more people come to realize that negative selftalk and negative energy can affect you in many ways and cause you additional stress. Because of this, developing more positive selftalk is an important way to reduce stress in your life. You can help yourself maintain a positive flame of mind, which will help with positive selftalk by surrounding yourself with positive energy in your life. You can getthat by adding some elements to your life.Listening to music that not only has a pleasant melody, but an uplifting message, can be great for developing positive selftalk. Have you ever had a song “stuck in your head” for a few hours or days, the lyrics repeating themselves in your mind? If those lyrics were positive and inspirational, that would be a good thing. It's a much better mental soundtrack to have than a running stream of complaints, criticisms of selflimiting thoughts, or even songs that had more depressing or sad lyrics.Bo oks on strength, personal power, enlightenment, or selfhelp can be good resources to help you change your outlook and the things you say to yourself. Rather than bringing habitual selfdefeating thoughts, you can find yourself thinking of new cando co ncepts when times get tough.One of the most important ways you can get and keep positive energy in your life is with the company you keep. Do your friends uplift you, or bring you down? Are they critical, or approving? Ideal friendships provide support when you're down, fun when you're up, wisdom when you're lost. Good friends can inspire you to reach greater heights, and see your strengths even when you don't always. Pay attention to how your friends make you feel, and if they're less than supportive, start putting your energy and time toward people who are better suited to be your friends.In addition, positive affirmations (肯定) can certainly change your selftalk from negative to positive. Now, why not begin working positive affirmations into your life in some creative ways?58.What does the passage mainly talk about?A.Adding some colorful elements to your life.B.Changing your selftalk with positive affirmations.C.Getting positive energy from the company you keep.D.Reducing stress by surrounding yourself with positive energy.59.How many ways does the author suggest to maintain a positive frame of mind?A.Three. B.Four.C.Five. D.Six.60.What will probably be talked about in the following paragraph?A.Some great ways of making great friends.B.How negative selftalk influences a person.C.Some creative ways of practicing affirmation.D.How positive selftalk reduces stress in one's life.答案Ⅰ.1.recipe 2.manual 3.centigrade 4.bent 5.breweryⅡ.6.glanced at7.achieve your purpose 8.an appropriate amount of 9.in other words 10.you should apologize to himⅢ.11.选D 根据前句:你真粗心,不关煤气就离开家,可知下句应是:我(这样做)的确粗心。
