四川省达州市2025届高三生物第一次诊断性测试试题含解析

四川省达州市2025届高三生物第一次诊断性测试试题（含解析）1.细胞中含有多种化合物，下列叙述正确的是A. 人体细胞中的氨基酸都是必需氨基酸B. 核酸都是遗传物质，糖类都是能源物质C. 自由水是良好的溶剂，脂肪是良好的贮能物质D. 多糖、酶的单体分别是葡萄糖、氨基酸【答案】C【解析】【分析】组成蛋白质的单体是氨基酸，人体细胞中部分氨基酸可通过转氨基作用形成，而不能合成的氨基酸叫做必需氨基酸。

多糖是由多个葡萄糖聚合形成的，故组成多糖的单体是葡萄糖。

酶的本质是蛋白质或RNA，蛋白质的基本组成单位是氨基酸，RNA的基本组成单位是核糖核苷酸。

【详解】人体细胞中的20种氨基酸，有8种是必需氨基酸，12种是非必需氨基酸，A错误；核酸不肯定都是遗传物质，如在细胞生物体内，DNA是遗传物质，RNA不是遗传物质；糖类物质并不都是细胞内的能源物质，如五碳糖是组成核酸的成分，纤维素是细胞壁的成分，二者都不作为能源物质，B错误；自由水是良好的溶剂，脂肪是良好的贮能物质，C正确；大部分酶的本质是蛋白质，少数酶的本质是RNA，因此组成酶的单体是氨基酸或核糖核苷酸，D错误。

故选C。

2.某同学用附着有过氧化氢酶的滤纸片进行了相关的试验探讨(如图所示，图中小圆圈为氧气气泡)，下列分析正确的是A. 酶促反应速率可用反应时间(t3-t1)的长短来表示B. 用附着等量FeCl3的滤纸片做试验，反应时间(t3-t2)变小C. 该装置可用于探究不同温度对过氧化氢酶活性的影响D. 变更过氧化氢溶液的pH，滤纸片不会接触烧杯底部【答案】A【解析】【分析】分析题图：图示试验装置用于探究影响酶促反应速率因素，过氧化氢酶能催化过氧化氢水解，酶促反应速率可以用滤纸片从进入液面之时到浮出液面的时间（即t3-t1）来表示，为了避开试验的偶然性，提高试验的精确性，应遵循平行重复原则，每个烧杯中需放多个滤纸片，再计算平均值。

【详解】附着有过氧化氢酶的滤纸片进入液面之时即起先了反应，故酶促反应速率可用反应时间(t3-t1)的长短来表示，A正确；酶具有高效性，其催化效率高于无机催化剂，因此用附着等量FeCl3的滤纸片做试验，反应时间(t3-t2)变长，B错误；因为过氧化氢不稳定，在高温下会自行分解，且分解速率和温度在肯定范围内成正相关，会对酶的催化分解造成干扰，因而该装置不行用于探究不同温度对过氧化氢酶活性的影响，C错误；变更过氧化氢溶液的pH，过氧化氢酶有可能失活，就不会使过氧化氢分解产生氧气，滤纸片会接触烧杯底部，D错误。

2023届四川省达州市高三上学期第一次诊断性测试理综生物试题(含答案解析)

D、能吸收蓝紫光和红光的叶绿素 a 含有 Mg 元素，D 不符合题意。
故选 C。 2．A 【分析】磷酸化是指蛋白质在蛋白激酶的作用下，其氨基酸的羟基被磷酸基团取代，变成有
活性有功能的蛋白质，去磷酸化是指磷酸化的蛋白质在蛋白磷酸酶的作用下去掉磷酸基团，
复原成羟基，失去活性的过程。
【详解】A、蛋白质磷酸化过程伴随 ATP 的水解，ATP 水解产生 ADP 和 Pi，并释放能量，生成的 Pi 转移到了蛋白质分子上，因此 ATP 为蛋白质磷酸化提供能量和磷酸基团，A 正确； B、由图可知，蛋白质的磷酸化过程要用蛋白激酶而去磷酸化过程要用蛋白磷酸酶，所以蛋

A man goes shopping 36 he needs something. His purpose is settled and decided in 37 . He knows what he wants, and hisgoal is to find it and buy it. All men 38 walk into a shop and ask the shopassistant for what they want. If the shop has it in stock (库存),the deal can be done and39is completed in lessthan five minutes, with hardly and chat to everyone’s 40 .For a man, slight problems may begin when the shop doesn’t have what he wants. In that 41 , the salesman tries to sellsomething else——he 42 the nearest to the article required. Agood salesman brings out such a substitute (替代品) 43 , and he may say: 〝44 know this jacket is not the style youwant, sir, but would you like to try it for size. It 45 to be the colour you mentioned.〞 Few menhave 46 with this treatment, and the usualresponse is: 〝This is the right colour and may be the right size, but I shouldn’tbe 47 my time and yours by trying it on.〞For a woman, buying clothes is always done in the 48 way. Her shopping is not often 49 on need. She has never fully decided whatshe wants, and she is only 〝having a look round〞. She is always 50 to persuasion, willing to try on anynumber of things. Deep in her mind is the thought of finding something that 51 thinks suits her. Most women have ane_cellent sense of value and are always on the look—out for the une_pected 52 . Faced with a roomful dresses, awoman may easily spend an hour going from one rail to another 53 selecting the dress she wants to try on.It is a tiresome process, but apparently a(n) 54 one.

Every year, on June 19 th, a professor from theUniversity of Pisa climbs to the bell tower and measures the increase in theslant (倾斜) withspecial instruments. And every year the professor makes the same report: thetower has leaned a bit—about an inch more. Last summer (the year of _), the 125—foot—high tower was leaning an incredible 15 feet out of line. Scientistssay that unless a way is found to stop the slant, the tower will collapse inless than 80 years.The tower is leaning because the soft soil of Pisa will not support it. Its foundation is sinking into the soil at an angle, causing the tower tolean. Since a slight shake could make the foundation loose, the ringing of thetower’s bells was forbidden in 1959. And trucks are not allowed to passin theneighborhood of the tower for this same reason.56．This passageis mainly about ___________.A．a famous tower that leans B.a plan for saving the towerC．the history of the Tower D.the cause of the tower’s slant57．This summerthe tower may be found to be in the slant by _________ according to the passage.A．more than one inch B.e_actly one inchC．more than fifteen feet D.e_actly fifteen feet58．Truck traffichas been forbidden in the neighborhood of the tower _________.A．to protect all the visitors B.to prevent the bell in the towerC．to protect the foundation D.to keep the soil at the tower59．According tothe way it is written, this passage is more like _________.A．a funny history story B.a serious tour advertisementC．an e_citing announcement D.a common science reportBThere is one word that is on the lips of Americans, day and night, 〝Sorry.〞One time as I was walking on the street, a young man ran byhurriedly, brushing against my handbag. Even as he continued on his way, heturned back and said 〝sorry〞 to me. Even in a rush, he didn’t forget toapologize.One day, after I bought some apples, the salesman was giving me the change, but I wasn’t ready for it, and a coin dropped on the ground. 〝I’m sorry〞,he said while bending down to pick it up. I was puzzled——why would heapologize when it wasmy fault?Another time, I stepped on a man’s foot in an escalator. At the same time, we both said 〝sorry〞. I thought it interesting: was it really necessaryfor him to apologize?Later on, an American friend e_plained to me that according to the American ideas, the escalator is a public place which everyone should be ableto stand in. After someone occupies a position in the escalator, making itdifficult for someone else to find a place to stand in, isn’t it necessary toe_press an apology?During my stay in America, I gradually realized that when friction (摩擦) occurs in daily life, Americansdon’t care much about who is responsible. If someone is troubled, a 〝sorry〞 isalways necessary. Even if the other person is hurt, the 〝sorry〞 would cooltempers. Perhaps this is why I never saw anyone quarreling on the buses, subways or streets in America.60．When I waswalking in the street, _________.A．a young man wanted to rob me of my bagB．a young man ran by and wanted to brush my bagC．a young man said sorry to me for touching my bagD．a young man came hurriedly to help me with my bag61．When thesalesman gave me the change, _________.A．I purposely didn’t want to accept it from the salesmanB．the salesman purposely didn’t want to pass it to meC．I was slower to accept it than the salesman to give it to meD．the salesman was slower to give it to me than I could accept it62．The man onwhose feet I stepped apologized to me because _________.A．the escalator is a public placeB．the man was very afraid of meC．the 〝sorry〞 said to me was foreveryoneD．there wasn’t enough room to get myfeet in63．In thispassage, the author seems to feel _________ the Americans’〝sorry〞.A．angry with B. disappointedwith C.interested in D. approving ofCThis is a rather strange story but it is quite true. In December 1996, a burglar broke into a golf club in a small town. When the police arrivedto investigate, they found an unusual clue (线索)—— a piece of cheese with a bite - mark in it. The burglar had gone into the kitchen, and hadeaten some food there. Then he had stolen some cigarettes and a little money.The policeman in charge of the case guessed that the burglar was a local man. He thought that professional thieves would not bother to break intoa golf club. They would know there was not much worth stealing in such a place.He made enquiries in the town and asked three suspects to come to the police station. When he questioned them about the burglary, they all denied stealingin the club. The policeman then gave each man a piece of cheese and asked himto bite it. He took the pieces of the cheese to a dentist and asked him tocompare the bite – marks with that in the piece of cheese found at the golfclub. Then the dentist said the bite – mark made by one of the suspects was thesame as that in the piece of cheese at the scene of the burglary.The policeman set free two of the suspects and questioned the third one. At first the man claimed that he was innocent. The policeman knew that theman was lying, so he encouraged him to talk until he began to contradict himself. Then the policeman told him about the bite – marks and the man had toadmit his stealing.64．This story isstrange because _________.A．a piece of cheese helped to catchthe thiefB．the burglar ate some food in thekitchenC．the burglar broke into a town golfclubD．the story happened in a very smalltown65．The policemanguessed the burglar was a local man according to the fact that _______.A．he had gone into the kitchen of theclubB．he stole only cigarettes and somecheeseC．it was different from skillfultheftD．there was nothing valuable in theclub66．The threesuspects were given a piece of cheese each because _________.A．a very important clue was a pieceof cheese with a bite – markB．all the suspects denied they hadstolen in the local clubC．in this way the policeman could askthe dentist for helpD．in this way the suspect was likelyto be found out67．The policemancan be best described as _________.A．very clever B. ratherstrict C. hard – working D. warm – heartedDWe can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. 〝Did Jerry really care whenI brokeup with Helen?〞〝When I got that great job, did Jim really feel good about it,as a friend? Or did he envy my luck?〞〝And Paul——why didn’t I pick up that he was unfriendly just because I had acar?〞 When we look back, doubts like these can make us feel bad. But when welook back, it’s too late.Why do we go wrong about our friends——or our enemies? Sometimes what people say hides their real meaning.And if we don’t really listen, we miss the feeling behind the words. Suppose someone tells you, 〝You’re a lucky dog.〞 Is he really on your side? If he says,〝You’re a lucky guy〞 or 〝You’re a lucky gal〞, that’s being friendly. But 〝luckydog〞? There’s a bit of envy in those words. Maybe he doesn’t see it himself. But bringing in the word 〝dog〞 puts you down a little. What he may be saying is that he doesn’t think you deserve your luck.〝Just think of all the things you have to be thankful for〞 is another noise that says one thing and means another. It could mean that the speaker istrying to get you to see your problem as part of your life as a whole. But ishe? Wrapped up in this phrase is the thought that your problem isn’t important.It’s telling you to think of all the starving people in the world whenyouhaven’t got a date for Saturday night.How can you tell the real meaning behind someone’s words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says agree with the tone of voice? His posture? The look in hiseyes? Stop and think. The minute you spend thinking about the real meaning ofwhat people say to you may save another mistake.68．In the lstparagraph, the writer recalls some things that happened between some friendsand they _________.A．think it was a mistake to havebroken up with their girl friendsB．feel happy, thinking of how nicetheir friends were to them in the pastC．feel very sorry that their friendsdidn’t help them and let them downD．feel they may not have 〝read〞 theirfriends’ true feeling correctly69．In thispassage, the writer tries to tell us how to _________.A．avoid mistakes about money and ourfriendsB．avoid mistakes in understandingwhat people tell usC．keep people friendly withouttrusting them any moreD．〝size up〞 people in a morescientific and meaningful way70．While we arelistening to a person, the important thing for us is _________.A．to check his words against hismanner, tone of voice and postureB．to notice his tone of voice, hisposture, and the look in his eyesC．to listen to how he pronounces hiswords in front of youD．not to believe what he says in anysituation or at any time71．According tothis passage, the underlined phrase 〝puts you down〞 can be replaced by another phrase 〝________〞.A．reduces you to silence B. presses you downC．makes you humble D.makes you sadEWhat’s on■Oscar FilmThemes Symphony ConcertFilm highlights accompanied by live performances of movie thememusic by the China Opera and Dance Drama Theatre Symphony Orchestra, which hasrecorded the music for many films.

解析：题干中sold的动作发生在过去，had的动作发生在sold之前，也就是“过去的过去〞，故用过去完成时。

【技巧点拨】熟记过去完成时的用法，别无他法。

【典型总结】过去完成时的根本用法归纳过去完成时表示一个动作或者状态在过去某一时间是或者动作之前已经完成或者完毕，即“过去的过去〞；也可以指过去的动作延续到过去的某个时刻。

这里的过去时间是可以用某个时间是状语表示，也可以通过上下文表示。

1〕表示一个动作或者状态在过去某一时间是或者动作之前已经完成或者完毕，也有可能早已完毕或者完成。

例如：When he was in Beijing, he visited places where he had played as a child. 他在的时候游览了他儿时曾玩过的地方。

2〕表示一个过去的动作先于另一过去的动作的用法，这种情况多见于宾语从句。

例如：He remembered that he had left the key at home. 他记得(jì de)他把钥匙落家了。
