Just as mankind has always had a desire to fly, the human race has wanted to swim under the water since prehistoric times. Pictures of primitive devices to enable people to breathe underwater have been found dating from 3000 years ago, but our dream of moving freely beneath the ocean waves for long periods of time was only realized about 60 years ago, when French diving legend Jacques Cousteau developed the first practical Self Contained Underwater Breathing Apparatus(SCUBA). Since then the sport of SCUBA diving has gone from strength to strength.
Lovers of SCUBA diving like the feeling of weightlessness, the peace and quiet under the water, the ability to move in three dimensions and the sense of adventure they get while on a dive. SCUBA divers often travel to some of the most beautiful and remote places in the world in the search for rare underwater flora and fauna(动、植物). Palau, The Red Sea, The Maldives and Hawaii have many of the most popular diving sites, but recreational divers often have to make do with less exotic local destinations, like the North Sea in Britain.
SCUBA diving is not without its dangers, however. The mixture of nitrogen and oxygen divers breathe underwater, combined with the pressure under the water can be deadly if a diver rises too quickly to the surface, causing a condition called ‘the bends’. Divers can also get lost or trapped when diving on wrecks, and fatalities(死亡)are particularly common in cave diving, where divers add to the dangers of diving by swimming through underground caves filled with water. Diving can also be harmful to the underwater environment. However with proper precautions diving can open up a whole new world, far from the stresses of daily life.

As a manager, Tiffany is responsible for interviewing applicants for some of the positions with her company. During one interview, she noticed that the candidate never made direct eye contact. She was puzzled and somewhat disappointed because she liked the individual otherwise.
He had a perfect resume and gave good responses to her questions, but the fact that he never looked her in the eye said “untrustworthy,” so she decided to offer the job to her second choice. “It wasn’t until I attended a diversity workshop that I realized the person we passed over was the perfect person.” Tiffany admits. What she hadn’t known at the time of the interview was that the candidate’s “different” behavior was simply a cultural misunderstanding. He was an Asian-American raised in a family where respect for those in authority was shown by turning away your eyes. “I was just thrown off by the lack of eye contact, not realizing it was cultural,” Tiffany says. “I missed out, but will not miss that opportunity again.”
Many of us have had similar experiences with behaviors we describe as different. As the world becomes smaller and our workplaces more diverse, it is becoming essential to expand our understanding of others and to reexamine some of our false assumptions (假设) .
Hire Advantage
At a time when hiring qualified people is becoming more difficult, employers who can have no personal biases (偏见) from the process have an obvious advantage. My company, Mindsets LLC, helps organizations and individuals see their own blind spots. A real estate (房产) agent we worked with illustrates the positive difference such training can make .
“During my Mindsets coaching period, I was taught how to own a diversified workforce. I employed people from different cultures and skill sets. The agents were able to make use of their full potential and experiences to build up the company. When the real estate market began to change, it was because we had a diverse agent pool that we were able to stay in the real estate market much longer than others in the same profession.”
Blinded by Gender
Dale is an account executive who attended one of my workshops in charge of a diverse workforce. “Through some of the lessons, I discovered my personal bias.” he recalls. “I learned I had not been looking at a person as a whole person, and being open to differences.” In his case, the blindness was not about culture but rather gender.
“I had a management position open in my department; and the two finalists were a man and a woman. Had I not attended this workshop, I would have automatically assumed the man was the best candidate because the position required quite a bit of extensive travel. My assumption would have been that even though both candidates were great and could have been successful in the position, I assumed the woman would have wanted to be home with her children and not travel.” Dale’s assumptions are another example of the well-intentioned but incorrect thinking that limits an organization’s ability to promote the full potential of a diverse workforce. “I learned from the class that instead of forcing my gender biases into the situation, I needed to present the full range of duties, responsibilities and expectations to all candidates and allow them to make an informed decision.” Dale sings high praise for the workshop, “because it helped me make decisions based on fairness.”
A better Bottom Line
An open mind about diversity not only improves organizations from inside, it is profitable as well. These comments from a customer service representative show how an inclusive attitude can improve sales.” Most of my customers speak English as a second language. One of the best things my company has done is to contract with a language service that offers translations over the phone. It wasn’t until my boss received Mindsets’ training that she was able to understand how important inclusiveness was to customer service. As a result, our customer base has increased.”
Once we start to see people as individuals, we can move positively toward inclusiveness for everyone. Diversity is about coming together and taking advantage of our differences and similarities and about building better communities and organizations. When we begin to question our assumptions and challenge what we think we have learned from our past , from the media, peers, family, friends, etc, we begin to realize that some of our conclusions are imperfect or contrary to our fundamental values. We need to train ourselves to think differently, shift our mindsets and realize that diversity opens doors for all of us, creating opportunities in organizations and communities that benefit everyone. In Tiffany’s view, the first candidate was passed over because he ________.
| A．was an Asian-American |
| B．didn’t perform as perfectly as the second one |
| C．was untrustworthy |
| D．showed no respect for authority |
Tiffany’s misjudgment about the candidate originated from ________.

| B．A hi-tech company. |
| C．A company dealing with financial affairs. |
| D．A company training workforce. |
Which of the following statements will Dale not agree with about Mindsets LLC’s workshop?
| A．It helped him make fair decisions. |
| B．It helped him discover his personal bias about gender. |
| C．It helped him look at a person as a whole one. |
| D．It helped him find successful candidates. |
The last paragraph is intended to tell us the importance of ________.

Sixteen years ago, Eileen Doyle’s husband, an engineer, took his four children up for an early morning cup of tea, packed a small case and was never seen or heard from again. Eileen was astonished and in a state of despair. They had been a happy family and, as far as she knew, there had been nothing wrong with their marriage.
Every day of the year a small group of men and women quietly pack a few belongings and, without so much as a note or a good-bye, close the front door for the last time, leaving their debts, their worries and their confused families behind them. Last year, more than 1,200 men and nearly as many women were reported missing from home — the highest in 15 years. Many did return home within a year, but others rejected the past completely and are now living a new life somewhere under a different identity.
To those left behind this form of desertion is a terrible blow to their pride and self-confidence. Even the finality of death might be preferable. At least it does not imply rejection or failure. Worse than that, people can be left with an unfinished marriage, not knowing whether they will have to wait seven years before they are free to start a fresh life.
Clinical psychologist Paul Brown believes most departures of this kind to be well planned rather than impulsive. “It’s typical of the kind of personality which seems able to ignore other people’s pain and difficulties. Running away, like killing yourself, is a highly aggressive act. By creating an absence the people left behind feel guilty, upset and empty.”Eileen Doyle reacted that way after her husband’s leaving, because she__________.
| A．failed to hear from him for a long time |
| B．had no idea what was wrong with their family life |
| C．blamed herself for something wrong she did |
| D．wondered why her husband took up all their children |
According to the passage, those people left their families behind for the following reasons except_________.
| A．they couldn’t bear their spouse (配偶) |
| B．they were afraid of the burden of debts |
| C．they wanted to forget the past completely |
| D．they wanted to start a new life somewhere else |
The man or woman left behind with an unfinished marriage usually ________.
| A．admits their responsibility for the situation |
| B．feels embarrassed and useless |
| C．will have no legal marriage life for seven years |
| D．wishes the person who has left were dead |
Some people would even prefer the death to the running away of their spouse because ________.
| A．their spouse would feel greatly relieved |
| B．their spouse would feel no pain during the death |
| C．their spouse’s death would contribute to them starting a fresh life |
| D．their spouse’s death would not bring a feeling of rejection or failure |
What’s the author’s attitude towards the departures of this kind?
| A．Objective. | B．Supportive. |
| C．Negative. | D．Positive. |
New research shows that the healthy brain may hold memories which we don’t even remember. In The Journal of Neuroscience, experts report that the brain might hold more memories than people realize, but that restoring those memories can be tricky.
Memory Check
First, participants saw a list of 120 real words mixed with 80 nonsense words. Next, they saw another word list and tried to remember which words had been on the first list. Meanwhile, their brains were scanned with functional magnetic resonance(核磁共振) imaging.
While participants reviewed the second word list, their brain scans showed more activity in a certain brain area -- the posterior（后部的） median temporal lobe(脑叶) -- when they saw words that had been on the first word list.
But participants didn’t always remember that they’d seen those words before. Sometimes, they goofed and said they hadn’t seen those words before. In other words, the posterior median temporal lobe was more sensitive to memory than participants’ consciousness, the researchers note.
“Album”of Memories
Another part of the median temporal lobe also attracted the scientists’ attention. The anterior（前面的）median temporal lobe showed more activity when participants thought they were seeing a new word, the study shows.
So, why did participants sometimes mess up their memory recall? It might be that two parts of their brain -- the posterior and anterior median temporal lobes -- might be dueling(决斗) for the upper hand in deciding what actually happened in the past, the study notes.
In other words, memories might have a photo album in the brain, but sometimes we forget what’s on all of the photo album’s pages.A person sometimes has difficulty recalling because .
| A．he is unconscious when he gets his memories |
| B．he forgets what is on the pages of the photo album |
| C．there are two parts in his brain dueling for the upper advantage |
| D．the anterior median temporal lobe is more active than the posterior |
According to the passage the researchers are .
| A．studying how a person remembers things |
| B．studying a magazine The Journal of Neuroscience |
| C．examining posterior and anterior median temporal lobes |
| D．doing experiments to find out what disturbs a person’s memory |
What did the experts discover when the participants saw the words on the first word list appear on the second word list?
| A．The instrument worked faster. |
| B．The participants were more conscious. |
| C．The posterior median temporal lobe was more active. |
| D．The anterior median temporal lobe was more active. |
The underlined wordgoofedin the fourth paragraph means .
| A．made a mess of | B．made an answer for |
| C．made out of | D．made the best of |
Researchers are now using 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation.
Dr. Bramlet, a children’s heart expert at the University of Illinois College of Medicine, says the 3-D models show information he cannot get any other way.
“And so what we’ve done with the printed models? We’ve pulled it out of the screen so that you can actually hold it in your hand and evaluate the anatomy（解剖）.”
A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model to understand the anatomy.
Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster（石膏）form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail. “When we’re done with the model and made our decision, we want to be able to go back to the source image and confirm those findings, he says.
Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby’s heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations.
Kathy Magliato is a heart surgeon at Saint John’s Health Center in Los Angeles. She welcomes the new technology. She says it could help her make better decisions before she operates on the hearts of her patients.
“I can then take this very complicated structure before the operation and I can hold it in my hand and plan an operation around what I’m seeing, touching and feeling. That to me is what can potentially change the game in an operation and save lives.
Dr Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.Whats the main idea of the passage?
| A．The application of 3-D printing in heart operations |
| B．The development of 3-D technology. |
| C．The difficulties of heart operations. |
| D．Heart operations with the help 3-D models. |
What is the biggest advantage of 3-D models in the diagnose of heart problems?
| A．Surgeons can see, touch and feel the 3-D models. |
| B．They can help surgeons save time. |
| C．They can be made exactly like the hearts. |
| D．They can help discover the otherwise hidden heart problems. |
Which of the following statements is TRUE?
| A．The 3-D model can be taken out of a screen. |
| B．CAT scan and MRI are no longer needed. |
| C．The 3-D model is an exact copy of the heart. |
| D．Digital images are not reliable in heart operations. |
What can we infer from the passage?
| A．Digital images will mislead heart surgeons. |
| B．More patients will benefit from the 3-D technology. |
| C．Heart operations will never fail with 3-D models. |
| D．Surgeons cannot operate on hearts without 3-D models. |
For many people shopping is considered to be one of the favorite activities. For most of them it is just buying some new clothes or presents for close people. But there is another way for whom shopping is much more than just enjoyable activity, it is a real addiction that in many cases leads to a financial disaster, as well as it brings troubles to person’s life and family.
So why can shopping be so addictive? What are the possible signs to be aware of? And how is it possible to stop the need of spending?
“Some of the new evidence suggests that some people, maybe 10%-15%, may have a genetic preference to an addictive behavior, coupled with an environment in which the particular behavior is caused, but no one really knows why.”However, it is much better understood as to why “shopaholics” continue with their unhealthy and destructive behaviors. Individuals get pleasure from their addiction the same way as if they were under drugs.
And when is it really possible to determine whether simple shopping has crossed the border and has already turned into addiction?
Shopaholics go out and buy things much more often than other people do. They often buy things they do not need. Many shopping addicts go on shopping binges(放纵) all year long and may be forced to buy certain items, such as shoes, clothing or kitchen items. Some just will buy anything. Many times they will spend over their budget limits and get into deep financial trouble, spending well above their income. While someone else will think many times if they can afford this or that thing, shop addicts will not recognize the boundaries of a budget.We can learn from the 3rd paragraph that .
| A．shopping addiction is mainly caused by genetic factors |
| B．shopping addicts are also addicted to drugs |
| C．the real cause of shopping addiction is known already |
| D．shopaholics can’t control their unhealthy and destructive behaviors |
The last paragraph is mainly about .
| A．the destructive behaviors of shopaholics |
| B．the early signs of shopping addiction |
| C．the problems of shopaholics |
| D．the binge of shopaholics |
What could be most probably discussed in the paragraph to follow the passage?
| A．How to treat shopping addiction. |
| B．What really causes shopping addiction. |
| C．When shopping addiction takes place. |
| D．What kind of people can become shopping addicts. |
It can be inferred from the passage that .
| A．shopping addiction can’t cause serious problems |
| B．shopping addicts only want enjoyable activities through buying |
| C．it’s not a good idea to let a shopping addict pay by credit cards |
| D．shopping addiction can spread among different people |
