Why do men die earlier than women? The latest research makes it known that the
reason could be that men’s hearts go into rapid decline when they reach middle age.
The latest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.The text mainly talks about ________.
| A．men’s heart cells | B．women’s ageing process |
| C．the gender difference | D．hearts and long life |
According to the text, the UK scientists have known that ________.
| A．women have more cells than men when they are born |
| B．women can replace the cells that enable the heart to beat |
| C．the female heart loses few of the cells with age |
| D．women never lose their pumping power with age |
We can know from the passage that ________.
| A．the reason why ageing takes a greater loss on the male heart has been found out |
| B．scientists are on the way to finding out why the male heart loses more of the cells |
| C．the team has done something to prevent the male from suffering the greater loss |
| D．women over 70 could lose more heart cells than those at the age of 20 |
Urbanization
(2013·高考北京卷)Until relatively recently，the vast majority of human beings lived and died without ever seeing a city.The first city was probably founded no more than 5,500 years ago.__ __In fact，nearly everyone lived on farms or in tiny rural (乡村的) villages.It was not until the 20th century that Great Britain became the first urban society in history—a society in which the majority of people live in cities and do not farm for a living.
Britain was only the beginning. __The process of urbanization—the migration (迁徙) of people from the countryside to the city—was the result of modernization，which has rapidly transformed how people live and where they live.
In 1990，fewer than 40% of Americans lived in urban areas.Today，over 82% of Americans live in cities.Only about 2% live on farms.__ __
Large cities were impossible until agriculture became industrialized.Even in advanced agricultural societies，it took about ninetyfive people on farms to feed five people in cities._ _Until modern times，those living in cities were mainly the ruling elite(精英) and the servants，laborers and professionals who served them.Cities survived by taxing farmers and were limited in size by the amount of surplus food that the rural population produced and by the ability to move this surplus from farm to city.
Over the past two centuries，the Industrial Revolution has broken this balance between the city and the country. _Today，instead of needing ninetyfive farmers to feed five city people，one American farmer is able to feed more than a hundred nonfarmers.
| A．That kept cities very small. |
| B．The rest live in small towns. |
| C．The effects of urban living on people should be considered. |
| D．Soon many other industrial nations became urban societies. |
E．But even 200 years ago，only a few people could live in cities.
F．Modernization drew people to the cities and made farmers more productive.
G．Modern cities have destroyed social relations and the health of human beings.
One might expect that the evergrowing demands of the tourist trade would bring nothing but good for the countries that receive the holidaymakers.Indeed，a rosy picture is painted for the longterm future of the holiday industry.Every month sees the building of a new hotel somewhere.And every month another rockbound Pacific island is advertised as the ‘last paradise(天堂) on earth’．
However，the scale and speed of this growth seem set to destroy the very things tourists want to enjoy.In those countries where there was a rush to make quick money out of seaside holidays，overcrowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.
Those countries with little experience of tourism can suffer most.In recent years，Nepal set out to attract foreign visitors to fund developments in health and education.Its forests，full of wildlife and rare flowers，were offered to tourists as one more untouched paradise.In fact，the nature all too soon felt the effects of thousands of holidaymakers traveling through the forest land.Ancient tracks became major routes for the walkers，with the consequent exploitation of precious trees and plants.
Not only can the environment of a country suffer from the sudden growth of tourism.The people as well rapidly feel its effects.Farmland makes way for hotels，roads and airports；the old way of life goes.The onetime farmer is now the servant of some multinational organization；he is no longer his own master.Once it was his back that bore the pain；now it is his smile that is exploited.No doubt he wonders whether he wasn’t happier in his village working his own land.
Thankfully，the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers.The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies.At the same time，tourists are being encouraged to respect not only the countryside they visit but also its people.
The way tourism is handled in the next ten years will decide its fate and that of the countries we all want to visit.Their needs and problems are more important than those of the tourist companies.Increased understanding in planning worldwide tourism can preserve the market for these companies.If not，in a few years’ time the very things that attract tourists now may well have been destroyed.What does the author indicate in the last sentence of Paragraph 1?

Home to me means a sense of familiarity and nostalgia(怀旧)．It’s fun to come home.It looks the same.It smells the same.You’ll realize what’s changed is you.Home is where we can remember pain，love，and some other experiences：We parted here；My parents met here；I won three championships here.
If I close my eyes，I can still have a clear picture in mind of my first home.I walk in the door and see a brown sofa surrounding a low glasstop wooden table.To the right of the living room is my first bedroom.It’s empty，but it’s where my earliest memories are.
There is the dining room table where I celebrated birthdays，and where I cried on Halloween－when I didn’t want to wear the skirt my mother made for me.I always liked standing on that table because it made me feel tall and strong.If I sit at this table，I can see my favorite room in the house，my parents’ room.It is simple：a brown wooden dresser lines the right side of the wall next to a television and a couple of photos of my grandparents on each side.Their bed is my safe zone.I can jump on it anytime－waking up my parents if I am scared or if I have an important announcement that cannot wait until the morning.
I’m lucky because I know my first home still exists.It exists in my mind and heart，on a physical property(住宅) on West 64th street on the western edge of Los Angeles.It is proof I lived，I grew，and I learned.
Sometimes when I feel lost，I lie down and shut my eyes，and I go home.I know it’s where I’ll find my family，my dogs，and my belongings.I purposely leave the window open at night because I know I’ll be blamed by Mom.But I don’t mind，because I want to hear her say my name，which reminds me I’m home.Why does the author call her parents’ bed her “safe zone”(Paragraph 3)?

“People are ruder today because they are rushed and more ‘time poor’ than ever before，”says Patsy Rowe，“ Manners_have_fallen_off_the_radar(雷达)．”Due to our strong attraction to electronic equipment it is a wonder more people don’t wake up each morning and greet the singing birds with a complaint(抱怨)about the noise.Here are some examples of rudeness.
Some people prefer to do almost everything over the internet.To them，dealing with an actual human is like an evolutionary step backward.It feels very slow because humans don’t work at 4G speeds.When you have dinner with friends，you will often notice someone paying more attention to his mobile phone.We have programmed ourselves to think that every new message brings lifechanging news，so taking calls and checking our texts are more important than talking to the people we are with.What is worse，some people even tend to send anonymous(匿名的) rude messages by email.
However，rudeness is never acceptable.Don’t assume it is OK to be rude if the person you’re in touch with won’t recognize you.If you have something awful to say，have the courage to face the person and say it，write a letter or email and sign it，or forget it.Upsetting people with unsigned messages is cruel and disgusting.
We shouldn’t blame technology for our shortcomings.Technology is here to help us，but we should not allow it to take over our lives.An important step ia acknowledging our shortcomings.People spend a lot of time pointing out bad manners but it would be even more helpful if we’d publicly acknowledge good manners when we see them.What can be inferred from the underlined sentence in Paragraph 1?
| A．People can tell good from bad behavior. |
| B．Radar is able to observe human behavior. |
| C．People care little about their behavior. |
| D．Radar can be used to predict human behavior. |
Some people are less willing to deal with humans because________.
| A．they are becoming less patient |
| B．they are growing too independent |
| C．they have to handle many important messages |
| D．they have to follow an evolutionary step backward. |
The author thinks sending unsigned awful messages is________.
| A．ridiculous | B．disgusting |
| C．acceptable | D．reasonable |
What can we learn from the last paragraph?
| A．We should applaud good behavior. |
| B．Technology can never be blamed. |
| C．We should keep pointing out mistakes. |
| D．Technology will take over our lives one day. |
Mark Twain has been called the inventor of the American novel.And he surely deserves additional praise：the man who popularized the clever literary attack on racism.
I say clever because antislavery fiction had been the important part of the literature in the years before the Civil War.H.B.Stowe’s Uncle Tom’s Cabin is only the most famous example.These early stories dealt directly with slavery.With minor exceptions，Twain planted his attacks on slavery and prejudice into tales that were on the surface about something else entirely.He drew his readers into the argument by drawing them into the story.
Again and again，in the postwar years，Twain seemed forced to deal with the challenge of race.Consider the most controversial，at least today，of Twain’s novels，Adventures of Huckleberry Finn.Only a few books have been kicked off the shelves as often as Huckleberry Finn，Twain’s most widely read tale.Once upon a time，people hated the book because it struck them as rude.Twain himself wrote that those who banned the book considered the novel“trash and suitable only for the slums(贫民窟)．”More recently the book has been attacked because of the character Jim，the escaped slave，and many occurrences of the word nigger.(The term Nigger Jim，for which the novel is often severely criticized，never appears in it.)
But the attacks were and are silly—and miss the point.The novel is strongly antislavery.Jim’s search through the slave states for the family from whom he has been forcibly parted is heroic.As J．Chadwick has pointed out，the character of Jim was a first in American fiction—a recognition that the slave had two personalities，“the voice of survival within a white slave culture and the voice of the individual：Jim，the father and the man.”
There is much more.Twain’s mystery novel Pudd’nhead Wilson stood as a challenge to the racial beliefs of even many of the liberals of his day.Written at a time when the accepted wisdom held Negroes to be inferior (低等的) to whites，especially in intelligence，Twain’s tale centered in part around two babies switched at birth.A slave gave birth to her master’s baby and，for fear that the child should be sold South，switched him for the master’s baby by his wife.The slave’s lightskinned child was taken to be white and grew up with both the attitudes and the education of the slaveholding class.The master’s wife’s baby was taken for black and grew up with the attitudes and intonations of the slave.
The point was difficult to miss：nurture (养育)，not nature，was the key to social status.The features of the black man that provided the stuff of prejudice—manner of speech，for example—were，to Twain，indicative of nothing other than the conditioning that slavery forced on its victims.
Twain’s racial tone was not perfect.One is left uneasy，for example，by the lengthy passage in his autobiography (自传) about how much he loved what were called“nigger shows”in his youth—mostly with white men performing in blackface—and his delight in getting his mother to laugh at them.Yet there is no reason to think Twain saw the shows as representing reality.His frequent attacks on slavery and prejudice suggest his keen awareness that they did not.
Was Twain a racist? Asking the questioning the 21st century is as wise as asking the same of Lincoln.If we read the words and attitudes of the past through the“wisdom”of the considered moral judgments of the present，we will find nothing but error.Lincoln，who believed the black man the inferior of the white，fought and won a war to free him.And Twain，raised in a slave state，briefly a soldier，and inventor of Jim，may have done more to anger the nation over racial injustice and awaken its collective conscience than any other novelist in the past century.How do Twain’s novels on slavery differ from Stowe’s?
| A．Twain was more willing to deal with racism. |
| B．Twain’s attack on racism was much less open. |
| C．Twain’s themes seemed to agree with plots. |
| D．Twain was openly concerned with racism. |
Recent criticism of Adventures of Huckleberry Finn arose partly from its________.
| A．target readers at the bottom |
| B．antislavery attitude |
| C．rather impolite language |
| D．frequent use of“nigger” |
What best proves Twain’s antislavery stand according to the author?
| A．Jim’s search for his family was described in detail. |
| B．The slave’s voice was first heard in American novels. |
| C．Jim grew up into a man and a father in the white culture. |
| D．Twain suspected that the slaves were less intelligent. |
The story of two babies switched mainly indicates that________.
| A．slaves were forced to give up their babies to their masters |
| B．slaves’ babies could pick up slaveholders’ way of speaking |
| C．blacks’social position was shaped by how they were brought up |
| D．blacks were born with certain features of prejudice |

| C．White men. |
| D．The shows. |
What does the author mainly argue for?
