Judy Wright and her husband decided to move closer to their son, Chris ,who lived in

Georgia. About a month after the move ,Judy fell ill, suffering from her ongoing battle against Parkinson’s disease.

Her condition worsened rapidly and she required medical care at home. The family

hired a nursing aid who canceled at the last minute. Instead , a woman named TunDe Hector showed up in her place.

One day, TunDe shared a story with Judy and her family. She remembered a particularly difficult day in 2014, when a stranger had helped her with a kind gesture. She

had run out of gas, and with only$5 in her pocket ,was walking to a gas station, gas can in

hand. A man saw her walking and turned his car around. He paid for her gas and gave her

all the cash left in his wallet. Upon hearing the story , Judy’s son, Chris, took off his hat and

said ,"That was me!” He was the stranger that had helped TunDe on that difficult day.

During the care of Judy, the Wright family learned about TunDe’s family and her own dream. The nursing aid, TunDe hoped that one day she could become an OB-GYN nurse.Her tuition was past due(逾期)and she had a family to care for, but she was determined to achieve that goal for herself and her family.

Judy died on July 9,2017. Instead of flowers, her family asked mourners(悼念者)to donate to TunDe’s education , to assist her in paying for her nursing school. In less than a

week, they raised more than $8,000 and presented her with the surprise check.

24. Why did Judy’s family choose TunDe in the end?

A. To help her with a kind gesture .

B. To replace another nursing aid.

C. To look after Judy in the hospital

C. Puzzled

D. Delighted

26. How did the Wright family help TunDe after Judy’s death?

B. They helped care for her family

C. They helped her realize her dream.

A. Kindness comes full circle

B. Actions speak louder than words.

C. The truth never fears investigation

D. Constant dropping wears stone.

A study showed that the experiences children have in their first few years are important . These experiences affect the development of the brain. When children receive

more attention, they often have higher IQs. Babies receive information when they see, hear

and feel things, which makes connections between different parts of the brain. There are a

hundred trillion(万亿)connections in the brain of a three-year-old child.

Researcher Judit Gervain tested how good newborns are at distinguishing different sound patterns. Her researchers produced images of the brains of babies as they heard different sound patterns. For example, one order was mu-ba-ba. This is the pattern"A-B-B". Another order was mu-ba-ge. This is the pattern “A-B-C”. T he images showed that the part of the brain responsible for speech was more active during the"

A-B-B"pattern. This shows that babies can tell the difference between different patterns. They also were sensitive to where it occurred in the order.

Gervain is excited by these findings because the order of sounds is the building block of

words and grammar."Position is key to language," she says. "If something is at the beginning or at the end, it makes a big difference:'John caught the bear.' is very different

from 'The bear caught John.'”

Researchers led by scientist Patricia Kuhl have found that language delivered by televisions, audio books,the Internet, or smartphones-no matter how educational-doesn’t

appear to be enough for children’s

brain development. They carried out a study of nine-month-old American babies. They expected the first group who’d watched v ideos in Chinese to show the same kind of learning as the second group who were brought face-to-face with the same sounds. Instead they found a huge difference. The babies in the second group were able to distinguish between similar Chinese sounds as well as native listeners. But the other babies -regardless of whether they had watched the video or listened to the audio-learned nothing.

28. What makes connections in a baby’s brain?

A. Having a higher IQ.

B. Experiencing new information

C. The baby’ early age

D. The connection with other babies

29. What did Judit Gervain and her team find in the experiment?

A. Babies identify different sound patterns.

B. Word order is relevant to meaning.

C. Babies can well understand different words.

D. A certain brain region processes language.

30. What does the underlined sentence mean in Paragraph 3?

A. Grammar is important in learning languages.

B. Different orders have different meanings.

C. Different languages have different grammar.

D. Words have different sounds.

31. What is the main conclusion from the study led by Patricia Kuhl?

A. Babies shouldn’t watch a lot of television.

B. Listening to different languages develops babies’ brain

C. Foreign langu ages help babies’ brain develop

D. Social communication improves babies’ brain development.

On average ,Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk , Strayer explained that all this time spent with technology is making our brains tired.

Using an electronic device to answer emails, listen to the news and look at Facebook

puts a lot of pressure on the front of the brain, which, Strayer explains , is important for

critical (有判断力的)thinking , problem-solving and decision-making.

So, it is important to give the brain a rest. And being in naure , Strayer claims , helps

get a tired brain away from too much technology. More than 15,000 campers from around

the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore , swim, sleep, eat and play. Camping may be just what a tired brain needs.

Take Carl for example .He lives in West Virginia and enjoys camping . He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping

regenerative” experience.

with her husband and two children . She calls it a “

At the University of Utah , David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However ,he found , it is

the long-term contact with nature that does the most good. He and his research team found

that spending three days in nature without any technology is enough time for the brain to

fully relax and reset itself.

32. What is David Strayer’s opinion ?

A. Americans dislike outdoor activities

B. Electronic equipment should be quitted

C. New technologies are a double-edged sword

D. Electronic equipment brings great convenience

33. Why does Strayer insist we go outdoors?

A. To try another lifestyle

B. To refresh our brain

C. To make better decisions.

D. To play with our family and friends

34. What does the underlined word “regenerative” mean?

A. Reborn

B. Memorable

C. Remarkable

D. Tiring

35. Which is the proper title for the passage?

A. Electronic Equipment Harms the Brain

B. Good Rest Develops Good Memory

C. Tips on Using New Technologies

D. Being in Nature Is Good for the Brain

宁夏银川一中2019届高三第一次模拟考试试卷(生物 解析版)

1.下列与细胞相关的叙述错误的是 A. 非细胞结构的病毒可以在宿主个体的血浆中繁殖后代 B. 运用差速离心法分离各种细胞器时必须先将细胞膜破坏 C. 肌细胞内的机质体是由大量变形的线粒体组成,与肌细胞能量供应有关 D. 水、O2、CO2、甘油、乙醇、苯均可以通过自由扩散进出细胞 【答案】A 【解析】 【分析】 病毒无细胞结构,必须寄生在活细胞内才能完成生命活动;差速离心法是将细胞膜破坏后,形成由各种细胞器和细胞中其他物质组成的匀浆,将匀浆放入离心管,用高速离心机在不同的转速下进行离心,利用不同的离心速度所产生的不同离心力,就能将各种细胞器分离开;线粒体是能量转换器,为生命活动提供能量;自由扩散的方向是从低浓度向高浓度,不需要载体和能量,如水,CO2,O2,甘油,苯、酒精等。 【详解】A. 非细胞结构的病毒必须寄生在活细胞中繁殖后代,A错误; B. 运用差速离心法分离各种细胞器,必须先将细胞膜破坏,再利用细胞各组分质量大小不同,在离心管不同区域沉降的原理,分离出所需组分,B正确; C. 肌细胞内的机质体是由大量变形的线粒体组成,推出该结构与肌细胞能量供应有关,C 正确; D. 水、O2、CO2、甘油、乙醇、苯进出细胞的方式是自由扩散,D正确。 2.除了温度和pH值对酶活性有影响外,一些抑制剂也会降低酶的催化效果。下图为酶作用机理及两种抑制剂影响酶活性的机理的示意图。下列说法不正确的是 A. 用胰蛋白酶处理生物膜可改变其通透性 B. 酶只能催化一种或一类化学反应,与酶自身结构有关 C. 非竞争性抑制可以改变酶的结构,使酶不适于接纳底物分子

D. 竞争性抑制剂降低酶活性的机理与高温、低温对酶活性抑制的机理相同 【答案】D 【解析】 【分析】 分析题图,在无抑制剂存在时,底物和酶结合后,在酶的催化下转化成产物;竞争性抑制剂和底物争夺酶的同一活性部位,使酶和底物的结合机会减少,从而降低酶对底物的催化反应速率,而非竞争性抑制剂会和酶活性位点以外的其他位点结合,通过改变酶的结构,从而使酶失去催化活性,降低酶对底物的催化反应速率。 【详解】A. 蛋白酶出能催化细胞膜上的蛋白质水解,因此细胞膜的通透性也改变,A正确; B. 酶具有专一性,一种酶只能催化一种或一类物质的化学反应,这与酶的空间结构有关,B 正确; C. 据图分析,非竞争性抑制可以与酶的非活性位点结合,改变酶的结构,从而使酶不能与底物结合,C正确; D. 竞争性抑制剂通过与底物竞争活性部位降低酶活性,而高温会使酶的空间结构破坏使酶失活,但低温只是抑制酶的活性,酶在低温下酶的空间结构没有改变,它们之间作用机理不同,D错误。 3.下列有关细胞生命历程的叙述错误的是 A. 细胞都要经过发生、生长、成熟、衰老和凋亡的过程 B. 在细胞衰老的过程中,细胞的生理状态和化学反应都会发生复杂的变化 C. 被病原体感染的细胞的清除属于细胞坏死 D. 紫外线及其他射线通过损伤细胞内的DNA分子导致细胞癌变 【答案】C 【解析】 【分析】 衰老细胞中,细胞内水分减少,细胞萎缩,体积变小,但细胞核体积增大,染色质固缩,染色加深;细胞膜通透性功能改变,物质运输功能降低;细胞色素随着细胞衰老逐渐累积;有些酶的活性降低;呼吸速度减慢,新陈代谢减慢。细胞凋亡是由基因决定的,属于正常的生命现象,对生物体有利;细胞坏死是由外界环境因素引起的,是不正常的细胞死亡,对生物体有害。紫外线、X射线等会损伤细胞中的DNA分子,使原癌基因和抑癌基因发生突变,导致正常细胞的生长和分裂失控而变成癌细胞。
