Across the world, studies have consistently found that girls perform significantly better than boys in reading. These studies show that girls typically read more frequently than boys, and have a more positive attitude toward reading.
There are several reasons that help explain these gender-based differences. Parents read more with their daughters. This sends a strong and early message that books are for girls, as well as equipping girls with a significant advantage. Recent research has found even though boys read less frequently than girls, girls still receive more encouragement to read from their parents.
So how can parents and educators help bridge this socially- engineered gap for boys ' reading?
To improve boys ' reading performance, parea n tds educators may look for ways to connect boys with reading. This has led to discussion about the importance of promoting so-called
“ bo-yfriendly ” books that boys supposedly “ prefer ” . These are typically a-sfsicutmioen d to be non
works, as many people believed that boys prefer to read non-fiction.
But this belief is not supported by recent research, which in fact suggests boys are more
likely to choose to read fiction than non-fiction. Encouraging all boys to read non-fiction under the mistaken belief that it is their preference may actually be harmful. Fiction readers read more frequently and demonstrate faster language learning and higher language ability.
Besides encouraging more fiction reading, there are a number of ways that we can help connect boys with books. Firstly, don' ta ssume that boys of the same age have the same interests or that their interests stay the same over time. To match boys with suitable reading material, have
regular discussions about reading for pleasure in order to keep up with their interests.
Schools should also provide access to libraries during lessons throughout the years of schooling. Girls visit the library in their free time more than boys, and as students move to higher grades they often have less access to libraries during class. Access to books for boys is essential to promote reading.
In addition, we should keep paper books available because research shows that boys are less likely to choose to read on screens than girls. Finally we should promote reading as an enjoyable pastime by being a role model. Let your children or students see you read for pleasure.
24.According to the author, what is the main cause of the difference in boys ' and
girls
ability?
A.Social factors.
B.Teaching methods.
C.Personal preferences.
D.Psychological differences.
25.Why does the author recommend that adults regularly talk to boys about reading?
A.To persuade boys to read more often.
B.To learn what boys are most interested in.
C.To help boys improve their language ability.
D.To show that adults are good reading role models.
26.When should schools give students additional library access according to the author?
A.Before and after class.
B.At any time of the school day.
C.At regular times during class.
D.When they are in the lower grades.
27.What is the main purpose of the text?
A.To show students ways to improve their reading.
B.To explain why boys are not as good at reading as girls.
C.To urge governments to provide more reading resources.
D.To provide strategies that can help improve boys ' reading ability.

“ Anything you want, anytime you need it. ”
The message appeared on computer screens across the country at the same time, on the same day: December 12th, at 12 p.m.. Simultaneously, important looking envelopes containing cards with the same message were hand-delivered to the offices of all the major news companies.
One found its way to the desk of Chris Lin, a business reporter at The Post. The card was beautifully designed – a black background with the words printed out in crisp white letters. There was no explanation on the back, just a website address. Chris went to the website. Its style was identical to the card 's aA n dy tsimaied: Starti“ng Tomorrow.
”
The next day websites and blogs were filled with articles theorising about Anytime . Was it a shopping website like Tao Bao or Amazon? A joke? Something illegal? Anytime' s marketing had worked –it was a household name before it 'd even made a single sale.
When the opening came, that day at noon, the Anytime website suddenly had a single field that read, “ Whatd o you want? ” Ally ou had to do was type the words into that box, and then specify how quickly you wanted your item delivered: within one, ten, or twenty-four hours.
Bloggers were the first to test the service. And their reviews were glowing. Within weeks, Anytime had become a part of daily life. Nobody used other delivery sites or the post anymore as Anytime was much cheaper and faster.
Chris still wondered what exactly Anytime was. He tried to find out who owned the company,
but it was registered in a small country that did not require such information to be made public. He did find some interesting facts, though. Anyone who challenged the company, it seemed, met with serious trouble. A government official critical of Anytime for avoiding tax was forced to leave
his position after news stories suddenly appeared claiming he was dishonest. The head of another company taking Anytime to court died in a car accident just days before the case was to begin.
Chris began making a list of all the people who had something terrible happen to them after opposing or criticising Anytime . By lunch, he had more than one hundred examples. Something was definitely wrong. Chris worked on his list the rest of the day, emailing people who could provide more information and looking through newspaper records. After working through the night, an exhausted Chris finally fell asleep at his desk at 4 a.m..
When he woke a few hours later, there was a message flashing on his computer screen: making trouble. ” Chris smiled. He had no intention of stopping now that he knew he was on the right track.
28.What was on the front of the card sent to Chris Lin?
A.An invitation to a company opening.
B.The website address of a new company.
C.The words “Anytime: Starting tomorrow
D.The words “ Anything you want, anytime you need i.t ”
29.Why did the company choose to send the cards to many news reporters?
A.Because it didn ' t have enough money for traditional advert.i sing
B.Because it wanted to attract the reporters as customers.
C.So the reporters would write stories about the new company.
D.So people would find the new company interesting.
30.What did Chris ' s research suggest abAonuyt time?
A.It may be very dangerous.
B.Its popularity would soon decrease.
C.It was doing business all over the world.
D.It was being widely criticised by journalists.
31.How did Chris feel at the end of the story?
A.Scared that he would get into trouble.
B.Confident that he would find the truth.
C.Nervous about what the company would do.
D.Satisfied that he had discovered the company ' s secret.
D
Inside a secured room in a beautiful castle near Paris, a small metal cylinder （圆柱体）rests on a shelf beneath a double set of bell jars. It has lain there for more than a century, its rest only occasionally disturbed when the room' tsh ree key holders perform a coordinated opening ceremony to let technicians enter and clean this precious piece of metal.
First, the cylinder is rubbed with a piece of soft, alcohol-soaked cloth.
with pure water. Finally, the 1kg cylinder is returned, carefully,
Then it is steamed
to its resting place.
Such attention to a lump of metal is unusual, but has a purpose. The castle houses the International Bureau of Weights and Measures and that piece of shining, circular metal is its holiest relic. It is the defining mass （质量） against which all other kilograms are measured.
This is the international prototype, or standard, of the kilogram. The IPK, in short.
Dozens of carefully weighted copies of the original have been made. They are stored around the world and used to standardise individual nations ' weights and measures systems.
But the days of the IPK, in its current form, are numbered. The International Bureau of Weights and Measures has decided to replace this single physical specimen with a more fundamental measurement – based on electric current – in order to define the mass of an object. The king of kilograms is about to be dethroned.
“Onek ey reason for doing this work is to provide international security, sa”ys Bureau spokesman Paul Robinson. “Iaf stthl e bcurned down tomorrow and the kilogram was destroyed,
we would have no reference left for the world 's metric weights system. There would be chaos. The
current definition of the kilogram is the weight of that cylinder in Paris, after all.
Another major motivation for the replacement of the IPK is the growing need to be able to carry out more and more precise measurements. “ Drugc ompanies will soon be wanting to use ingredients that will have to be measured in terms of a few millionths or even billi onths of a gram, ”
says Robinson. “We need to be prepared to weigh substances with that kind of accuracy.
32.What do we know about the IPK from the first two paragraphs?
A.It 's cared for with great devotion.
B.It 's used in religious ceremonies.
C.It 's beautifully designed and decorated.
D.It 's the most valuable metal in the world.
33.Which of the following best explains “ dethroned ” underlined in paragraph 5?
A.rebuilt
B. removed
C. destroyed
D. upgraded
34.What is a reason for replacing the current IPK?
A. To protect the metal cylinder from damage.
B.To make taking measurements more economical.
C.To provide all countries with the same standard.
D.To satisfy the increasing demand for exactness.
35.What can be a suitable title for the text?
A. No more kilos
B. A heavy technology
C.The future of the kilo
D.The history of measures

It was the 2015 “ super storm ” in New South Wales that restored my faith in people.
During a break in the weather, I stupidly decided to drive into town to buy some groceries. However, as I left the supermarket and drove back, the weather took a turn for the worse. 36 Having nowhere to go, I spotted a young man in his front yard assessing the situation. He quickly waved to me to come and park in his driveway. 37
The man, who introduced himself as Trent, then invited me to wait inside his house with his wife, Kayti and their two daughters. I told him I was concerned about the damage to my car, as the continuing rain was starting to turn into hail （冰雹）. Trent then grabbed a blanket from his garage and covered my car. 38 Fortunately, his efforts saved my car from being damaged by the hail.
By 11:00 a.m., the electricity and phone services had both gone. 39 Trent made me a
cup of tea and Kayti gave me a towel to dry myself off. The three of us chatted while waiting for the weather to get better. I learned that Trent had lost his job and was struggling to feed the family.
When the hail stopped, I shook Trent 'has nd and kissed Kayti goodbye. 40 I was very moved by their kindness and it renewed my faith in people.
As I went out the door, I asked Trent for two of his business cards. My father has since called
to offer him a job as a clerk at his company.
A. It began pouring so heavily that I was forced to stop.
B.The couple were so modest as I thanked them for their help.
C.I was surprised that he didn ' t ask for anything in return for his assistance.
D.I was grateful to escape the running water that was about to drown my car.
E.I tried driving faster to escape the heavy downpour that was sure to come.
F.As a result, I couldn ' t contact my parents, despite knowing they ' d be worried.
G.He was wet but he didn ' t seem to mind being out in the wild weather on my behalf.

Why study history?
People live in the present. They plan for the 41 . History, however, is the study of the past. Given all the 42 and pressures that come from living in the present and 43 what
is yet to come, why bother with what has been? Given all the available branches of knowledge, why insist –as most 44 systems do –on history? And why urge many students to study even more history than they are 45 to?
Any subject of study needs 46 : supporters must explain why it is worth 47 . Like most widely accepted 48 , history attracts people who simply 49 the information and
modes of thought involved. But for people who are less interested in the subject and more 50
about why they should bother with it, a clearer explanation of its purpose is required.

In a society that quite correctly expects education to serve 52 purposes, history ' s functions can seem more difficult to 53 than those of engineering or medicine. History is in fact very useful, actually 54 , but the products of historical study are often less 55 and immediate
than those of other subjects.
History helps us understand people, societies and how they 56 . For example, how can we 57 past wars (and future threats) without using historical materials? Unfortunately, major aspects of a society 'opse ration cannot be set up as precise experiments. 58 , history must serve, however imperfectly, as our 59 , helping us understand who we are and why we do
what we do. This, fundamentally, is why we cannot 60 history.

64 (surprise), rather than run away, he jumped down and walked casually to a spot on
the path, not a metre from 65 we sat. The children were spellbound, the raccoon providing better 66 (entertain) than any museum. He glanced at us, perhaps checking to see 67
we were about to steal his lunch.
68 delicate fingers, he peeled back the layers of plastic wrap until the half-eaten sandwich 69 (uncover).
Then he surprised us all. Instead of starting his food, he turned to a nearby pool of water and

第二节
I wish to choose Mulan as my favourite cartoon character .
Living in ancient times, Mulan is a young girl who decides to go to join the army as a way to help her family. Because her baby brother is too young to enlist, she makes this sacrifice in order to stop the forced recruitment of her father. As only men could join the army in these times, Mulan disguises herself as a man to trick the army officers.
I really love this character because she is both brave and caring. She fights with courage and determination and she makes a great contribution to her country. She is also a wonderful role model, showing women, and people in general, that they need not feel limited about what they can achieve.

One was a beautiful living-room door, and the other was just a / an 16 bathroom door. What they had in 17 was that both led awful lives. The house was full of 18 children who were always slamming （摔门）and kicking the doors. Each night, when everyone was asleep, the doors would talk about their poor 19 . The living-room door was always ready to 20 with anger, but the bathroom door would calm him down, saying “Don’t worry. They’re chi ldren. They’ll soon learn. Be patient and things will21.” And so the living-room door would calm down for a while. But one day, after a big party and much slamming and kicking of the doors, the living-room door22lost his temper, saying, “That’s enough!The next time someone slams me, I’m going to 23 , and they’ll learn a thing or two.” The next day, the first time he was slammed, the living-room door broke. This caused great 24in the house, and the children were punished. The living-room door was filled with 25 . However, after a few days, the house owner got tired of the26 of having a broken door. Instead of mending the door, they decided to27it. The old door was thrown into the rubbish. There lay the beautiful living-room door,28what he had done. For not being29 enough, he now found himself abandoned, waiting to be turned into firewood. Meanwhile, his
2019年广州市普通高中毕业班综合测试（一） 理综生物试题 1.下列关于细胞结构与功能的叙述，错误的是 A. 细胞核：控制着细胞的代谢和遗传 B. 线粒体：丙酮酸氧化分解与ATP合成 C. 液泡：植物进行细胞代谢的主要场所 D. 中心体：与动物细胞的有丝分裂有关 【答案】C 【解析】 【分析】 本题考查细胞结构和功能，要求考生识记细胞核的结构和功能、细胞中各种细胞器的结构、分布和功能，能结合所学的知识准确判断各选项。 【详解】细胞核是遗传物质贮存和复制的场所，是细胞遗传和代谢的控制中心，A正确；线粒体是细胞有氧呼吸的主要场所，可以对丙酮酸氧化分解并有ATP的合成，B正确；植物进行细胞代谢的主要场所是细胞质基质，C错误；中心体在有丝分裂时发出星射线形成纺锤体，D正确。 【点睛】真核细胞进行有氧呼吸的主要场所是线粒体，这是因为线粒体内有大量的与有氧呼吸有关的呼吸酶，原核生物没有线粒体但是有些生物照常可以进行有氧呼吸，原因是也有与有氧呼吸有关的呼吸酶，所以有氧呼吸不一定有线粒体。 2.“无细胞蛋白质合成系统”是以外源DNA 或 mRNA为模板，人工添加所需原料和能源物质，以细胞提取物为条件合成蛋白质的体外基因表达系统。下列叙述错误的是 A. 人工添加的原料中应包含氨基酸 B. 该系统具备完成转录和翻译的能力 C. 为保证编码目标蛋白的mRNA数量应适当添加RNA酶 D. 与胞内蛋白质合成相比，该系统的蛋白质合成过程更易被人工调控 【答案】C 【解析】 【分析】 本题以信息给予的形式考查基因的表达过程，旨在考查考生信息获取的能力与知识迁移运用能力，知识点
较为综合，难度适中。 【详解】基因的表达包括翻译过程，翻译是以氨基酸为原料的，A正确；由题干信息“无细胞蛋白质合成系统是合成蛋白质的体外基因表达系统”可知，该系统具有表达能力，即具备完成转录和翻译的能力，B正确；RNA酶会破坏RNA结构，故为保证编码目标蛋白的mRNA数量，不应添加RNA酶，C错误；因该系统是在细胞外进行，操作环境更便利，故与胞内蛋白质合成相比，该系统的蛋白质合成过程更易被人工调控，D正确。【点睛】正确解答此题需要明确“表达”的含义：包括转录和翻译过程。 3.下列关于物质转运的叙述，错误的是 A. 被动运输与主动运输可受同种因素影响，如温度 B. 主动运输需要消耗能量，如池水中的K+进入丽藻细胞 C. 蛋白质可经核孔进入到细胞核中，如DNA聚合酶、RNA聚合酶 D. 胞吐运输的都是生物大分子，如乙酰胆碱、胰岛素 【答案】D 【解析】 【分析】 本题考查物质跨膜运输的方式、核孔的功能、质壁分离等相关知识，意在考查学生的识记物质跨膜运输的特点和影响因素，理解质壁分离的水分运输方向，识记核孔的功能和结构，属于中档题。 【详解】温度可影响蛋白质的功能，进而影响需要载体蛋白协助的被动运输与主动运输，A正确；池水中的K+进入丽藻细胞方式为主动运输，该过程需要耗能，B正确；一些大分子蛋白质如DNA聚合酶、RNA聚合酶等可通过核孔进入细胞核，C正确；胞吐运输的不一定都是生物大分子，如神经递质中的NO等，D错误。【点睛】K+的跨膜运输方式不一定是主动运输，如在神经细胞电位变化时，通过离子通道进出细胞时，不消耗能量。 4.下列有关真核生物的叙述，正确的是 A. 象与鼠相应组织和器官的大小差异主要决定于细胞数量的多少 B. 人的成熟红细胞中，与血红蛋白合成有关的基因处于活动状态 C. 克隆羊的成功证明已分化的动物细胞可直接发育成完整的个体 D. 衰老的细胞中，黑色素的合成加快，因此老年人会长“老年斑” 【答案】A 【解析】 【分析】

These studies show that girls typically read more frequently than boys, and have a more positive attitude toward reading. There are several reasons that help explain these gender-based differences. Parents read more with their daughters. This sends a strong and early message that books are for girls, as well as equipping girls with a significant advantage. Recent research has found even though boys read less frequently than girls, girls still receive more encouragement to read from their parents. So how can parents and educators help bridge this socially-engineered gap for boys’ reading? To improve boys’ reading performance, parents and educators may look for ways to connect boys with reading. This has led to discussion about the importance of promoting so-called

2006学年度广州市高中学生学业水平测试 语文（必修）模拟题 高二语文中心组编制 第一部分阅读与鉴赏（51分） 一、现代文阅读（25分） （一）阅读下面的新闻报道，完成1～2题。（6分） 3.5万救命钱留给病友 一名患白血病近两年的青年教师，本来有希望通过干细胞移植手术得以康复。因无法筹齐做手术所需的巨额费用，他毅然决定放弃治疗，并将剩下的救命钱送给病友——前日19时许，当彭敦辉送走病友欧阳志成回到病房后，看到了欧阳志成留给他的3.5万元现金和两封信。读罢信件，捧着救命钱，彭敦辉顿时泪雨滂沱。 家住浏阳市文家市镇伍神岭村的彭敦辉，1999年高中毕业后苦学食品加工技术，2000年在老家开办了食品加工厂，直到今年1月生意才稍有起色。去年底，他感觉到身体有些不舒服，经医生仔细检查，被确诊为白血病。今年3月，他来到湘雅医院住院治疗。不到半年时间，家里便负债20多万元。而接下来的干细胞移植手术，还需要数十万元费用。 现年29岁、在隆回山区当中学教师的欧阳志成，前年下半年不幸也患了白血病。今年8月9日，他再次来到湘雅医院治疗。恰好住在彭敦辉邻床。欧阳志成和彭敦辉的身材、脸型非常相像，而且两人都戴着帽子和眼镜。医护人员和病友都说他俩酷似亲兄弟。由于相同的命运和际遇，他俩成了一对无所不谈的好朋友，经常来到楼下散步，相约共同战胜病魔。 前不久，欧阳志成和彭敦辉的骨髓都配上了型，只待完成干细胞移植手术，便有望完全康复。为了筹集这笔手术费用，欧阳志成和年仅23岁的妻子四处奔走，尽管有关部门向他伸出了援助之手，但仍有10多万元不能到位。在这种情况下，欧阳志成决定放弃治疗。而彭敦辉的手术费用也差一大截，由于一时借不到这么多钱，他和家人同样心急如焚。 前日傍晚，欧阳志成不顾医护人员和彭敦辉的强烈反对，执意办理了出院手续。彭敦辉将欧阳志成送到楼梯口后，欧阳志成马上催他回去，说给他留下了一件礼物放在病床旁的抽屉里面。彭敦辉打开抽屉一看，里面是码放得整整齐齐的3.5万元现金，以及分别写给他和医院院长的两封信。在写给院长的信中，欧阳志成表示，他已留下遗嘱，让家人在其去世后将遗体捐赠给医院作解剖研究之用，为攻克白血病尽自己最后的微薄之力。 彭敦辉立即跑下楼，但早已不见了欧阳志成的身影。他马上拨通了欧阳志成的手机。欧阳志成说完“我走了，兄弟保重”几个字后，便匆匆挂断了电话。 （长沙晚报记者陈国忠）
