“I’ve never met a human worth cloning,” says cloning expert Mark Westhusin from his lab at Texas A&M University. “It’s a stupid endeavor.”
That’s an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two cows and a cat.
They just might succeed in cloning Missy soon — or perhaps not for another five years.
Westhusin's experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog's eggs, the A&M team has produced only a dozen or so embryos carrying Missy's DNA. None have survived the transfer to a surrogate（代孕的）mother. The wastage of eggs and the many spontaneously aborted(流产，发育不全) fetuses（胎）may be acceptable when you're dealing with cats or bulls, he argues, but not with humans. “Cloning is incredibly inefficient, and also dangerous,” he says.
Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1996, Westhusin's phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. “A lot of people want to clone pets, especially if the price is right,” says Westhusin. Cost is no obstacle for Missy's mysterious billionaire owner; he's put up $3.7 million so far to fund A&M's research.
Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy's fine qualities after she does die. The prototype（原型；雏形）is, by all accounts, athletic, good-natured and super-smart. Missy's master does not expect an exact copy of her. He knows her clone may not have her temperament（气质、性情）. In a statement of purpose, Missy's owner and the A&M team say they are “both looking forward to studying the ways that her clones differ from Missy.”
Besides cloning a great dog, the project may contribute insight into the old question of nature vs. nurture. It could also lead to the cloning of special rescue dogs and many endangered animals.
However, Westhusin is cautious about his work. He knows that even if he gets a dog pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems~ “Why would you ever want to clone humans,” Westhusin asks, “when we're not even close to getting it worked out in animals yet?”By “stupid endeavor”, Westhusin means to say that ________.
| A．human cloning is a foolish undertaking |
| B．animal cloning is absolutely impractical |
| C．human cloning should be done selectively |
| D．animal cloning is not worth the effort at all |

| A．Its success is already in sight. |
| B．It is progressing smoothly. |
| C．It is doomed to utter failure. |
| D．Its outcome remains uncertain. |

| B．search for ways to modify its temperament |
| C．find out the differences between Missy and its clones |
| D．examine the reproductive system of the dog species |

Dear Dad,
Today I was at the shopping mall and I spent a lot of time reading the Father's Day cards. They all had a special message that in some way or another reflected how I feel about you. Yet as I selected and read, it occurred to me that not a single card said what I really want to say to you.
You'll soon be 84 years old, Dad, and you and I will have had 55 Father's Days together. I haven't always been with you on Father's Day but I've always been with you in my heart.
You know, Dad, there was a time when we were separated by the generation gap. You stood on one side of the Great Divide and I on the other.
The Father-Daughter Duel shifted into high gear ( 档位) when you taught me to drive the old Dodge and I decided I would drive the '54 Chevy whether you liked it or not. The police officer who sent me home, after you reported the Chevy stolen, didn't have much tolerance for a stubborn 16 year old, while you were so tolerant about it, Dad, and I think that was probably what made it the worst night of my life.
Our relationship greatly improved when I married a man you liked, and things really turned around when we began making babies right and left. Somewhere along the line, the generation gap disappeared. I suppose I saw us and our relationship as aging together, rather like a fine wine.
But the strangest thing happened last week. I was at a stop sign and I watched as you turned the corner in your car. It didn't immediately occur to me that it was you because the man driving looked so elderly and fragile behind the wheel of that huge car. It was rather like a slap in the face delivered from out of nowhere. Perhaps I saw your age for the first time that day.
I guess what I'm trying to say, Dad, is what every son and daughter wants to say to their Dad today. Honoring a father on Father's Day is about respect and sharing and acceptance and tolerance and giving and taking. It's about loving someone more than words can say, and it's wishing that never had to end.
I love you, Dad.
Love,
JennyHow did Jenny probably feel on the night she was sent home by the police?

| D．had a hard time understanding each other |

| D．remind him of the early incident |
Someday a stranger will read your e-mail 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 to find out your shopping preferences or calling habits.
In fact, it’s likely some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girl friend, 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 --- the 21st century equivalent of being caught naked.
Psychologists tell us boundaries are healthy, that it's important to reveal yourself to friends, family and lovers in stages, at appropriate times.But few boundaries remain. The digital bread crumbs (碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think. 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 say they are concerned about losing it. A survey found an overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is “slipping away, and that bothers me.”
But people say one thing and do another. Only a tiny fraction 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. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acauisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon (优惠卷).
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.What does the author mean by saying “the 21st century equivalent of being caught naked” (Para. 2)?
| A．People tend to be more frank with each other in the information age. |
| B．In the 21st century people try every means to look into others’ secrets. |
| C．People's personal information is easily accessed without their knowledge. |
| D．Criminals are easily caught on the spot with advanced technology. |
What would psychologists advise on the relationships between friends?
| A．Friends should open their hearts to each other. |
| B．There should be a distance even between friends. |
| C．Friends should always be faithful to each other. |
| D．There should be fewer disputes between friends. |
Why does the author say “we live in a world where you simply cannot keep a secret” ( para. 3)?
| A．People leave traces around when using modern technology. |
| B．Modern society has finally evolved into an open society. |
| C．There are always people who are curious about others’ affairs. |
| D．Many search engines profit by revealing people’s identities. |
What do most Americans do with regard to privacy protection?
| A．They change behaviors that might disclose their identity. |
| B．They use various loyalty cards for business transactions. |
| C．They talk a lot but hardly do anything about it. |
| D．They rely most and more on electronic devices. |
According to the passage, privacy is like health in that .
| A．people will make every effort to keep it |
| B．its importance is rarely understood |
| C．it is something that can easily be lost |
| D．people don’t cherish it until they lose it |
“When I grow up, I want to be...”
Almost all of us have thought about, or been asked to think about, our future careers. Our answers may differ greatly. Even now your aspirations may have changed from when you were in primary school.
However, it seems career options aren’t only based on personal taste. In a survey carried out by Teens, doctors, lawyers, and bankers were some of most popular careers that people said they hoped to follow. This is in line with a similar survey carried out in the UK in May 2011 by job website monster. Co.uk, in which medicine was the top choice among UK teenagers aged between 13 and 17.
Medicine and law are two of the oldest and best known professions. Their prestige (威望) may come from the fact that doctors and lawyers are some of the most esteemed members of society, and they make good money. Joining these high-profile professions is often seen as a sign of upward social mobility.
It is equally unsurprising that banking is now one of the most common career choices. Youngsters worldwide think of banking and see the money rolling in. Wealth is increasingly becoming one of the most important indicators of a successful career. British young men list the UK tycoon Alan Sugar, Microsoft founder Bill Gates and Facebook chief Mark Zuckerberg as their top role models “for their wealth”. Just as Chinese teenagers see being a banker as a good and fun pathway to “wealth”.
However, not every child has the makings of doctor, lawyer, or banker. They are those who see fulfillment and happiness in other areas, and many teenagers dare to ink more individuality into their career options. As the Teens’ survey discovered, a variety of unconventional jobs---coffee shop owner, gourmet(美食家)，waiter at a fast food restaurant---are among teenagers’ career choices. They can be equally interesting and rewarding jobs.
With every choice comes responsibility and challenge, and all career paths require specific education and training, you have to learn to balance optimism and confidence with being realistic about your particular talents and skills.What is the passage mainly about?
| A．Choosing a good job is very important. |
| B．Careers in teenagers’ mind. |
| C．Teenagers in the UK like doctors. |
| D．The choice of career needs challenge. |

It was a comfortable sunny Sunday. I was going to meet an old university friend I hadn't seen for years, and was really excited to hear all his news.
My train was running a little late, but that was no big problem - I could text him to say I would be delayed. He would understand. But… where was my mobile phone? I had that familiar sinking feeling. Yes, I'd forgotten it at home.
No mobile phone. I'm sure I'm not alone in feeling anxious, on edge and worried when I don't have my phone with me. In fact, I know I'm not alone: two-thirds of us experience ‘nomophobia’, the fear of being out of mobile phone contact.
That's according to a study from 2012 which surveyed 1,000 people in the UK about their relationship with mobile phones.
It says we check our mobile phones 34 times a day, that women are more ‘nomophobic’than men, and that 18-24 year-olds are the most likely to suffer fear of being without their mobiles: 77% of them say they are unable to be apart from their phones for more than a few minutes.
Do you have nomophobia ?
· You never turn your phone off
· You obsessively check for texts, missed calls and emails· You always take your phone to the bathroom with you· You never let the battery run out
It's funny to think that around 20 years ago the only people with mobile phones would be businessperson carrying their large, plastic ‘bricks’. Of course, these days, mobile phones are everywhere. A UN study from this year said mobile phone subscriptions would outnumber people across the world by the end of 2014.
And when there are more phones than people in the world, maybe it's time to ask who really is in charge? Are you in control of your phone, or does your phone control you?
So, what happened with my university friend? When I arrived a few minutes late he just laughed and said: "You haven't changed at all – still always late!" And we had a great afternoon catching up, full of jokes and stories, with no interruptions and no nagging(唠叨的) desire to check my phone.
Not having it with me felt strangely liberating. Maybe I'll leave it at home on purpose next time.What does the passage talk about ?
| A．The history of mobiles. |
| B．The story of meeting an old university friend. |
| C．The addiction of playing mobile phone. |
| D．The terrible feeling of being without their mobiles. |

| A． nervous | B．energetic | C．crazy | D．surprised |
Which word is used to describe old mobile phones according to the passage?
| A．digital phone | B．cell phone | C．bricks | D．smart phone |
According to the passage, who is most likely to be addicted to mobiles ?
| A．a successful manager | B．a 21-year-old girl |
| C．a 21-year-old boy | D．a lonely middle-aged person |
What’s the author’s attitude towards the using mobiles ?
| A．Worried | B．Favorable | C．Neutral | D．Critical |
For their nick-of-time acts, Toby, a 2-year-old dog, and Winnie, a cute cat, were named Dog and Cat of the Year by the American Society for the Prevention of Cruelty to Animals.
As Amy Paul choked(哽住) on a piece of apple at her home, her dog jumped up, landing hard on her chest and forcing the piece in her throat out. When the Keesling family of Indiana was about to be killed by carbon monoxide, their cat clawed at the wife Cathy’s hair until she woke up and called for help.
No one could explain their timely heroics.
Both pets were rescued by their owners in infancy---Toby as a 4-week-old thrown into a garbage bin to die, and Winnie as a week-old orphan hiding under a barn, so helpless that Cathy’s husband, Eric, had to feed her milk with an eyedropper.
As the Keeslings recalled it, a gas-driven pump being used broke down, spreading carbon monoxide through the house. By the time Winnie went to rescue, the couple’s 14-year-old son was already unconscious. “Winnie jumped on the bed and was clawing at me, with a kind of angry sound,” Cathy Keesling said. The state police responding to her 911 call said the family was only minutes from death, judging by the amount of poisonous gas in the house.
Amy Paul’s husband was at his job when she took a midday break from making jewelry and bit into an apple. “Normally I peel them, but I read in Good Housekeeping Magazine that the skin has all the nutrients, so I ate the skin, and that’s what caused me to choke,” she recalled. “I couldn’t breathe and I was in panic when Toby jumped on me. He never does that, but he did, and saved my life.”
Both Toby and Winnie accompanied their owners to the awards luncheon.Why did Amy Paul choke on a piece of apple?
| A．She was too young to care for herself. |
| B．She didn’t peel the skin as usual. |
| C．The apple was too hard. |
| D．She had a big bite. |
Winnie saved the lives of its owner’s whole family in an accident by __________.
| A．jumping onto its owner |
| B．calling for help |
| C．clawing at Cathy’s hair |
| D．making some strange noises |
Which of the following has the similar meaning to the underlined word “infancy” in Paragraph 4?
| A．middle age | B．youth | C．babyhood | D．agedness |
What caused the carbon monoxide spreading through the house?
| A．A pump breaking down. |
| B．A driver breaking into the house. |
| C．The burning gas. |
| D．The poisonous gas. |
What would be the suitable title for the passage?
| A．So Smart Animals Are |
| B．Great Honors for Cat and Dog |
| C．Unforgettable Experiences |
| D．Dog and Cat Honored for Saving Their Masters |
