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 largest 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 underlined word “longevity” in the second paragraph probably refers to ________.

A.health B.long life C.ageing D.effect

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

If you want to live longer, you should ________.

A.enable your heart to beat much faster B.find out the reason for ageing
C.exercise regularly to keep your heart healthy D.prevent your cells from being lost

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

“What’s in a name?”According to Shakespeare’s Romeo and Juliet,there is not too much.“That which we call a rose by any other name would smell as sweet.”But Shakespeare may have been wrong.In most cultures,names matter a great deal.
Americans choose names for their children with care.Parents usually think about the impression a name gives,not its meaning.Most Americans would consider a“Jennifer”more attractive than a “Bertha”,for example.The last name,or,surname,must also be considered when choosing a first and middle name.A name like Lester Chester Hester would sound poetic,but odd.Parents would avoid names that remind them of people they don’t like.On the other hand,people might name their children after a respected elderly relative or even a famous person.The popularity of certain names can change with each new generation.Names that were once common,like Fanny or Elmer,sound old-fashioned today.But other names—like John and David,Mary and Sarah—have stood the test of time and continue to be favorites.
People in Ameica don’t always call their friends and relatives by their given names.Instead,they often use nicknames.Sometimes nicknames are short forms of a longer name.For instance,a girl named Elizabeth may be called Lisa,Beth or Betsy.As children grow up,they may decide for themselves which nickname they wish to be called.Some people just go by the initials of their first and middle names,like B.J.or R.C.And of course,people may call their children or their sweethearts other special nicknames.Often they have a “sweet” flavor,like Honey or Sugar.What’s in a name? A world of significance.So if you’re choosing an English name for yourself,take care to choose a good one.Amade-up name could sound strange to native English speakers.And a translation of your Chinese name may not make an appropriate name,either.But a good name can leave a positive and lasting impression.As an American politician once said,“In real life,unlike in Shakespeare,the sweetness of the rose depends upon the name it bears.”
1.What does the underlined sentence in paragraph 2 mean?
A.People change names in order to be popular with the new generation.

B.you can name after a well-known person
C.surname should be paid attention to
D.you can create a name that is special

Geniuses amaze us,impress us and make us all a little jealous.How do they differ from the average person? Scientists are working hard to figure out that answer.Tune in to the National Geographic Channel to find out about the discoveries they’re making in the series My Brilliant Brain.
When Marc Yu was only two years old,he began to play the piano.After a year,he started learning pieces by Beethoven.Now he’s a world-famous concert pianist at age eight.He learns newer and more difficult pieces with ease and can identify any note he hears.He seems to be specially designed for music.In Born Genius,National Geographic looks at the science behind child prodigies(神童) to explain why some children seem to be born without limits.
Genius didn’t come naturally to Tommy McHugh.His came only after he nearly died from bleeding in his brain.Afer recovering,McHugh’s head was filled with new thoughts and pictures.So, he began to express them in the form of poetry and art.Now,he’s a seemingly unstoppable creative machine.Sufferers of autism and brain injury have shown that great mental ability can sometimes come from damage or disease.Accidental Genius explores this puzzling relationship.
Can normal people be trained to be geniuses?Susan Polger has shown no signs of extraordinary intelligence.Yet,during her childhood,she studied thousands of chess patterns and learned to recognize them immediately.As a result,she was able to beat skilled adult players by age 10 and can now play up to five games at the same time without even seeing the boards.Make Me a Genius examines what it takes to turn an ordinary brain into that of a genius.
If becoming a genius were easy,we’d all be one.Yet,there is much more to super intelligence than simply being born lucky.Learn more about amazing brains this month on National Geographic’s My Brilliant Brain.

WASHINGTON—It’s a great achievement that inspires notions of robots with consciousness and independent minds.
When people or animals get hurt,they can usually compensate for minor injuries and keep limping along,but for robots,even slight damage can make them stumble and fall.However,a recently made robot has demonstrated a novel ability:it can heal its own damage.
The new robot,which looks like a splay-legged,four-footed starfish can sense injury to itself and adapt.That ability sets the new robot apart from earlier machines.Because the robot can recover from unfamiliar places.“There is a need for planetary robotic rovers to be able to fix things on their own,” says Josh Bongard,a professor in the University of Vermont,who is one of the device’s creators.“Robots on other planets must be able to continue their mission without human help if they are damaged and cannot communicate their problem back to Earth.”
A typical robot functions according to a computer program,but the new robot works differently.First,sensors in its four legs observe the robot’s movements and signals to its built-in computer.From the formation it collects,the robot creates its own programs that allow it to adapt to different situations.For example,when the researchers shortened one of the robot’s legs,the smart machine simply adjusted its way of walking—it used three legs instead of four.
The researchers are looking for other places to put the resilient robot to work.One pellicle spot is the ocean floor.That dark and dangerous undersea terrain might be a good choice for a robot the scientists call the Starfish.“We never officially named the robot,but we usually refer to it as the Starfish,even though a real starfish has five rather than four legs,”says Bongard.“Also,a real starfish is much better than our robot at recovering from injury,because it can actually grow its legs again.”Scientists have created robots that help humans in many ways:by exploring space,fighting fires,and even performing surgery.
1.The newly designed robot distinguishes itself from the former ones because it _________ .
A.can communicate with people on the earth about their problems
B.works according to a certain computer program
C.can find its problems and solve them automatically
D.can explore unfamiliar places
2.An example is given in the fourth paragraph in order to explain that the robot_________.
A.is used to create new programs
B.has typical robot functions
C.has sensors to observe its movements
D.can gather information and adapt to new conditions
3.The underlined word“resilient”in the last paragraph means the robot is_________.
A.creative B.newly made C.able to recover D.informative
4.Which of the following is TURE about the robot “Starfish”?
A.It was spoken highly of by people for its special ability
B.It will stumble and fall if damaged.
C.It can grow its legs again once they are broken.
D.It has started to work on the ocean floor.
5.What might be the best title of the passage?
A.How does the Starfish Robot work B.Do-It-Yourself Robot Repair
C.Robots Designed to Work on Other Planets D.New Robot Helping Us in Many Ways

第三部分阅读理解(共20小题;每小题2分,满分40分)
阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。
Can you imagine a stranger will read your e-mails without your permission or scan the website you’ve visited or perhaps someone will casually glance through your credit card purchases or cell phone bills? All of the things may happen to you one day.
In fact,it’s likely that some of these things have already happened to you.Who would watch you without your permission? It might be a spouse,a girlfriend,a marketing company,a boss,a cop or a criminal.Whoever it is,they will see you in a way you never intended to be seen or even do something that may bring a disaster to you.
Psychologists tell us boundaries are healthy,and that it’s important to reveal to friends,family and lovers at appropriate times.But few boundaries remain nowadays.The digital bread crumbs(碎屑)you leave everywhere make it easy for strangers to know who you are,where you are and what you like.In some cases,a simple Google search can leak the deepest thought in your mind.Like it or not,increasingly we live in a world where you simply cannot keep a secret.
The key question is:Does that matter? For many Americans,the answer apparently is“no”.
When opinion polls ask Americans about privacy,most of them say they are really concerned about losing it.And 60 percent of the respondents say they feel their privacy is “slipping away,and that bothers me”.
But people say one thing and do another.Only a small of Americans change any behaviors in an effort to preserve their privacy.Few people turn down a discount at tollbooths(收费站)to avoid using the EZ-Pass system that can track automobile movements.Privacy economist Acquisti has run a series of tests that reveal people will give up personal information such as telephone number,address,or social security numbers just to get their hands on a pitiful 50-cents-off coupon(优惠券).But privacy does matter—at least sometimes.It’s like health;when you have it,you don’t notice it.Only when it’s gone do you wish you’d done more to protect it.Without privacy,one will be naked in front of others.

A.No privacy,no health.
B.Treasure your privacy.

D.The information age has its own shortcomings.

We often don' t give importance to minor things thinking they won' t matter. But at times, some things look very minor but their result can be really powerful. Here are some of the efforts which can change the relationship between parents and children.
Pat your child when he loses:May it be failure in the class, or on the field, speak words of encouragement to your child. The trust and confidence in your relationship will go to another level. After all, words of encouragement during failure are more valuable than words of praise after success.
Give him importance, like a member of the family:Hang his painting in your room or in the office, take his opinion when you are buying furniture for the house. Your child will believe in himself and be a winner throughout.
Share your own experience when your child makes a mistake:When you see your child lying or stealing, share with him the mistakes you made in your life. He' 11 know it is all right to make mistakes and that he can share with you anything.
Appreciate at least one quality in your child every day:Each day look at what qualities your child possesses and appreciate him, maybe for his caring attitude, his dance skills or his observation power. Tell him how proud you are of him because of those qualities.
Become his age before bedtime:Jump on the bed, have pillow fights, act silly, dance—become a child with your child for sometime. You' 11 forget all your day's stress.
Try these minor things; you' 11 see the love deepen and the relationship blossom.
