14．Every human being has a unique（唯一的，独特的） arrangement of the skin on his fingers and this arrangement is unchangeable．Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children，though nobody knows why this is the case．
　The ridge structure on a person's fingers does not change with growth and is not affected by surface injuries．Burns，cuts and other damage to the outer part of the skin will be replaced in time by new one，which bears a reproduction of the original（最粗的，原始的） pattern．It is only when the inner skin is injured that the arrangement will be destroyed．Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take．
　Finger-prints can be made very easily with printer's ink．They can by recorded easily．With special methods，identification（辨认，鉴定） can be achieved successfully within a short time．Because of the simplicity and economy of this system，finger-prints have often been used as a method of solving criminal case．A suspected man may deny a charge but this may be in vain．His finger-prints can prove who he is even if his appearance has been changed by age or accident．
　When a suspect leaves finger-prints behind at the scene of a crime，they are difficult to detect with the naked eye．Special techniques are used to"develop"them．Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained．

4．The uninvolved dad，turning up his nose at diapering（换尿布） and too busy to bathe，dress and play with his kids，is mostly a myth（神话），a big government survey suggests．Most American fathers say they are heavily involved in hands-on parenting，the researchers found．
The results are encouraging and important"because others have found the more involved dads  are，the better the outcomes for their children．"said researcher Jo Jones of the National Center for  Health Statistics，part of the Centers for Disease Control Prevention．She co-authored the report  released Friday．
"Times have changed，"said Robert Loftus，34，of Yonkers，NY．He quit a six-figure sales  job a year ago to care for his two young children while his wife works full time．"We are trying to  rethink our priorities （优先考虑的事）and family seem to be N0 1  priority while in the past maybe people were more focused on career．"
The study involved nearly 4.000fathers who were interviewed in person between 2009and 2013．
◇Key findings among fathers living with children younger than 5：
*9in 10bathed，diapered，helped them use the toilet or get dressed at least several times weekly．
*Even higher numbers played with them and ate meals with them that often
*Almost 2 0ut of 3read to them at least several times weekly．
◇Among dads living with kids aged 5-18．
*More than 9 0ut of 10ate meals with them at least several times weekly and talked with them about what happened during the kids'day that often．
*Almost 2 0ut of 3helped with homework several times weekly．
*About half took their kids to or from activities that often．
Dr．David Hill，a Wilmington，N．C．pediatrician （儿科医生） said the survey reflects what he's seen among his patients'fathers．Increasingly，fathers rather than mothers take their kids to the doctor．Some"are anxious about changing a diaper，"he said．
Census（调查） numbers show that there were almost 190，000stay-at-home dads nationwide last year versus 93，000in 2010．Loftus，the New York stay-at-home dad，said，"I feel fortunate to be able to be such a hands-on father．I'm doing the most significant occupation in the world．"

26．What can we learn about the research？D
A．It aimed to study fathers'influence on kids．
B．It showed most fathers often helped kids learn．
C．It found most fathers played with kids every day．
D．It mainly surveyed fathers'living with young kids．

B．He prefers to work full time．
C．He needs his wife's support very much．

D．American dads more involved in parenting．
5．For many years there's been a debate about rewarding our children．Does it work？Is it effective？
Some people think we should establish a standard with our kids and give them something for meeting this standard as a reward．Punishment is given out in much the same way，but it's used when certain standards of performance，behavior，etc．have not been met．Kids will often become more dutiful when threatened with punishment，and work harder when promised a valuable reward．The problem is what happens when you aren't around．
To develop responsible，self-disciplined（自律的）kids，parents need to promote certain ideas．One of these ideas is that everyone pitches in（努力投入）and helps in your family，even if someone is not crazy about helping．Another idea is that there can be enjoyment in doing any task if we choose to make it so．When a task is for a worthy cause（our family can enjoy the house more because I helped clean it），and when parents are cheerful about their chores，this message can have a big impact．
This is how we help our kids develop a sense of responsibility．When our children develop this responsibility，they'll be more disciplined，and they'll control their emotions better．When we give rewards to our kids，we reduce the sense of responsibility．We also create children who may temporarily（临时）perform to a certain standard，but who aren't likely to continue the performance without  the carrot  hanging in front of them．
"Rewards and punishment can change behavior for a while，but they cannot change the person who engages in the behavior，at least in the way we want，"said AIfie Kohn，author of Punished by Rewards．"Good values have to be grown from the inside out．''Parents can help give their children a sense of shared responsibility and discipline which can last a lifetime．The real rewards that your children receive will be their readiness for the complex and demanding world that waits for them---a world that rewards those who have learned the secrets of discipline responsibility．So keep those shiny rewarding to yourself，and let your kids find their own rewards．

66．According to the passage，when children are threatened with punishment，B．
A．they may lose interest in their work    
B．they may appear to be well-behaved
C．they may change to another person     
D．the results will be worse than usual
67．What can we know from Paragraph 3？A
A．Parents should promote certain ideas to help children develop．
B．Children should be responsible for their discipline．
C．Children should help build a good family atmosphere．
D．No children will adapt to society without their parents'help．
68．The underlined part"the carrot"in Paragraph 4probably refers toA．
A．rewards    B．aims    C．apologies   D．doubts
69．According to the passage，Alfie Kohn would agree that parents shouldD．

2．It's time to do something for your father-the man who for many people has been an encouragement and support since birth．The third Sunday of June is Father's Day．The holiday honors not only fathers，but also all men who act as father figures，such as stepfathers，uncles and grandfathers．
The idea of Father's Day came from the love and appreciation of American lady called Sonore Smart Dodd in 1909．Dodd wanted a special day to honor her father，William Smart．Heraised six children by himself on a countryside farm in Washington State after his wife died during the birth of their sixth child．When Dodd became an adult，she realized the selflessness her father has shown in raising his children as a single parent．It was her father who did all for his children．In the eyes of his daughter，William Smart was a courageous，selfless and loving man．Dodd's father was born in June，so she chose to hold the first Father's Day celebration in Washington on June 19th，1910．
In 1924，US President Calvin Coolidge supported the idea of a national Father's Day．Finally，in 1966，President Lyndon Johnson declared the third Sunday of June as Father's day．
So this is a perfect chance to let your father know what he means to you．To show your love and respect，you need not buy an expensive gift．You can send him a home-made card； You can call him every day； Even you can give him a sweet smile when he comes back from work．All these little things are easy for us to do，but they can show your care and love to your father．

9．It was once unheard-of to be a businessman in China．Nowadays，though，it's quite common to become your own boss．Let's say you have an idea．Maybe you want to open an English school or sell Japanese comics．First，you need a business plan．It sets out what you'll sell and how much everything will cost．Most businesses that fail didn't have this．If you need to borrow money at the start，banks will ask for a detailed plan．
The best starting place for a business plan is the 4Ps：product，place，price and promotion．All these must be strong to be successful．
□Product
Your product must have something unique．What makes it special compared to other similar products？If you want to start a noodle shop that has nothing new，don't expect people to show much interest．You can research your product．For food，let people try it for free．For toys，let a few children play with them to see if they like them．
□Place
There's no point having a product that people want to buy if your shop is in an empty mall．Think about which type of person is going to buy what you sell．Where do they usually go shopping？When looking at possible places，spend the day there．See how many people pass by．Also，are there other shops nearby selling similar products？If so，how can you be better than them？
□Price
Work out how much it costs to make or provide your product．As a general rule，your price will be double the cost．After all，you're also paying for rent，staff and you need to eat too!
□Promotion
How can you attract people to your shop？Advertising in newspapers and on TV is expensive．Perhaps you can get free advertising by getting a newspaper to write about your business．

26．What's the best title for the passage？C
A．How to start a business．
B．Starting a business soon．

19．Laptop computers are popular all over the world．People use them on trains and airplanes，in airports and hotels．These laptops connect people to their workplace．In the United States today，laptops also connect students to their classrooms．
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want．Within five years，each of the 1500 students at the college will receive a laptop．The laptops are part of a＄10 million computer program at Westlake，a 110-year-old college．The students with laptops will also have access to the Internet．In addition，they will be able to use e-mail to"speak"with their teachers，their classmates，and their families．However，the most important part of the laptop program is that students will be able to use computers without going to computer labs．They can work with it at home，in a fast-food restaurant or under the trees-anywhere at all!
Because of the many changes in computer technology，laptop use in higher education，such as colleges and universities，is workable．As laptops become more powerful，they become more similar to desktop computers．In addition，the portable computers can connect students to not only the Internet，but also libraries and other resources．State higher-education officials are studying how laptops can help students．State officials are also testing laptop programs at other universities，too．
At Westlake College，more than 60 percent of the staff use computers．The laptops will allow all teachers to use computers in their lessons．As one Westlake teacher said，"Here we are in the middle of Virginia and we're giving students a window on the world．They can see everything and do everything．"

6．Any mistake made in the printing of a stamp raises its value to stamp collectors．A mistake on a two-penny stamp has made it worth a million and a half times its face value．
Do you think it impossible？Well，it is true．And this is how it happened．
The mistake was made more than a hundred years ago in the former British colony（殖民地）of Mauritius，a small island in the Indian Ocean．In l847all order for stamps was sent to London Mauritius was about to become the fourth country in the world to put out stamps．
Before the order was filled and the stamps arrived from England，a big dance was planned by the commander-in-chief of all the armed forces on the island．The dance would be held in his house and letters of invitation would be sent to all the important people in Mauritius．Stamps were badly needed to post the letters．Therefore，an islander，who was a good printer，was told to copy the pattern of the stamps．He carelessly put the words"Post Office"instead of"Post Paid"，two words seen on stamps at that time，on the several hundred that he printed．
Today，there are only twenty-six of these misprinted stamps left-fourteen One-penny Reds and twelve Two-penny Blues，Because there are so few Two-penny Blues and because of their age，collectors have paid as much as﹩16，800for one of them．

55．Mauritius is the name ofD

3．How far would you be willing to go to satisfy your need to know？Far enough to find out your possibility of dying from a terrible disease？These days that's more than an academic question，as Tracy Smith reports in our Cover Story．
There are now more than a thousand genetic（基因的）tests，for everything from baldness to breast cancer，and the list is growing．Question is，do you really want to know what might eventually kill you？For instance，Nobel Prize-winning scientist James Watson，one of the first people to map their entire genetic makeup，is said to have asked not to be told if he were at a higher risk for Alzheimer'（老年痴呆症）．
"If I tell you that you have an increased risk of getting a terrible disease，that could weigh on your mind and make you anxious，through which you see the rest of your life as you wait for that disease to hit you．It could really mess you up．"Said Dr．Robert Green，a Harvard geneticist．
"Every ache and pain，"Smith suggested，could be understood as"the beginning of the end．""That's right．If you ever worried you were at risk for Alzheimer's disease，then every time you can't find your car in the parking lot，you think the disease has started．"
Dr．Green has been thinking about this issue for years．He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer's．It was thought that people who got bad news would，for lack of a better medical term，freak out．But Green and his team found that there was"no significant difference"between how people handled good news and possibly the worst news of their lives．In fact，most people think they can handle it．People who ask for the information usually can handle the information，good or bad，said Green．
71．The first paragraph is meant toB．
A．ask some questions              
B．introduce the topic
C．satisfy readers'curiosity         
D．describe an academic fact
72．Which of the following is true of James Watson？D
A．He is strongly in favor of the present genetic tests．
B．He is more likely to suffer from Alzheimer's disease．
C．He believes genetic mapping can help cure any disease．
D．He doesn't want to know his chance of getting a disease．
73．According to Paragraphs 3 and 4，if a person is at a higher genetic risk，it isA．
A．advisable not to let him know       
B．impossible to hide his disease
C．better to inform him immediately
D．necessary to remove his anxiety
74．The underlined part"freak out"in Paragraph 5 is closest in meaning to"A"．
A．break down        B．drop out     C．leave off        D．turn away
75．The study led by Dr．Green indicates that peopleC．
A．prefer to hear good news    
B．tend to find out the truth
C．can accept some bad news    
D．have the right to be informed．
4．Gone are the days when men and women couldn't associate（交往）with each other．When we are asked whether boys and girls can associate with each other，most of us will say，"Yes，of course．Why not？"
If we want to deal with the association between boys and girls properly，here are some"dos and don'ts"for you to follow．
1．Keep a normal and healthy state of mind（心态）． Our schools and classes are made up of boys and girls．It is very natural for boys and girls to contact each other and build up the friendship with the students of the other sex．Generally speaking，we should broaden the circle of the association．We should make as many friends as possible．We should have more friends of the other sex instead of one or two．We should contact the students in public instead of in secret．
2．Contact students of the other sex warmly，generously and sincerely．Don't be too nervous or too shy in contact with a person of the other sex．In that case it is very difficult for you to make a lot of friends，as no one likes a person who is too shy to say a word．If you are too shy a person，you can also find a way out．First of all，you can contact the students with the same interest and hobby with you．As both of you have much in common，you may have much to talk about．If you keep doing like that，little by little，you will gladly find you are also as free to express yourself as others．
3．Don't fall into the ditch（泥潭）of early love．The boys and girls at adolescence（青春期）are rich in feeling and full of imagination．They are easy to regard the friendship as a sign of love and fall in love with each other at an early age．In my opinion，boys and girls at middle school are too young and too tender to shoulder the heavy duty of love．Early love is a green apple that can't be eaten．An apple won't taste sweet until it is fully ripe（成熟）．Do keep out of early love．
61．The main idea of the passage is toB．
A．tell students to keep away from early love
B．give some advice on how to associate between boys and girls
C．say contact does good not only to boys but also to girls
