2020年职称英语教材新增文章（理工类）第二篇 Baby Talk
Babies normally start to talk when they are 13 to 15 months old. Ryan Jones is only eight months old, but he is already “talking” with his parents. When lie is hungry, he opens and closes his hand. This means milk. He also knows the signs for his favorite toy and the word more.(环球网校2020年

Ryan is not deaf, and his parents are not deaf, but his mother and father are teaching him to sign. They say a word and make a sign at the same time. They repeat this again and again. When 1 Ryan’s paren ts think that he will be a happier baby because he can communicate with them.
Ryan s parents are teaching Ryan to sign because of a man named Joseph Garcia. Although Garcia was not from a deaf family, he decided to learn American Sign Language (ASL). First, he took courses in ASL. Then he got a job helping deaf people communicate with hearing people. In his work, he saw many deaf parents sign to their infants. He noticed that
these babies were able to communicate much earlier than
hearing children. 2 When they were one year old, they could use as many as 50 signs.
Garcia decided to try something new. He taught ASL to parents who were not deaf. The families started to teach
signs to their infants when they were six or seven months old.
3 More and more par ents took Garcia’s ASL classes. Like Ryan’s family, they were excited about signing with their babies. They wanted to give their babies a way to communicate
before they could use spoken words.(环球网校2020年职称英语理工类教材新增文章汇总)
Some people worry about signing to babies. They are
afraid that these babies won’t feel a need to talk. Maybe they will develop spoken language later than other babies. 4 In fact, one study found just the opposite. Signing babies actually learned to speak earlier than other children. As
they grow older, these children are more interested in books. They also score higher on intelligence tests1.
There is still a big question for parents： Which are the best signs to teach their babies? Some parents make their own signs. Other parents want to teach ASL. 5 There，s no clear answer, but we do know this： All signing babies and their families are talking quite a lot!

Common Questions about Dreams
Does everyone dream?
Yes. Research shows that we all dream. We have our most vivid dreams during a type of sleep called Rapid Eye Movement (REM) sleep. During REM sleep, the brain is very active. The eyes move quickly back and forth1 under the lids, and the large muscles of the body are relaxed. REM sleep occurs every 90-100 minutes, three to four times a night, and it lasts longer as the night goes on. 1 We dream at other times during the night, too, but those dreams are less vivid.
Do people remember their dreams?
A few people remember their dreams. However, most people forget nearly everything that happened during the night 一dreams, thoughts, and the short periods of time when they were awake.(环球网校2020年职称英语理工类教材新增文章汇总)
2 It seems that the memory of the dream is not totally lost，but for some reason it is very hard to bring it back2. If you want to remember your dream, the best thing to do is to write it down as soon as you wake up.
Are dreams in color?
Most dreams are in color. However, people may not be aware of it for two reasons ： They don，t usually remember
the details of their dreams, or they don，t notice the color because it is such a natural part of our lives. 3 Do dreams have meaning?
Scientists continue to debate this issue.3 4 Some people use dreams to help them learn more about their feelings, thoughts, behavior, motives, and values. Others find that dreams can help them solve problems. It’s also true that artists, writers, and scientists often get creative ideas
from dreams.
How can I learn to understand my dreams?
The most important thing to remember is that your dreams are personal. The people, actions, and situations in your dreams reflect your experience, your thoughts, and your feelings. Some dream experts believe that there are certain types of dreams that many people have, even if they come from different cultures or time periods. Usually, however, the
same dream will have different meanings for different people. For example, an elephant in a dream may mean one thing to a zookeeper and something very different to a child whose
favorite toy is a stuffed elephant. 5 Then look for links between your dreams and what is happening in your daily life. If you think hard and you are patient, perhaps the meaning of your dreams will become clearer to you.
词汇：
vivid /'vivid/ adj.清晰的，生动的，逼真的 lid /lid/ n.眼
睑(=eyelid) motive /mautiv/ n.动机 stuffed/stAft/ adj.填充的，塞满了的
注释：
1. back and forth：来回地，反复地。
2. bring it back：回忆起它来。bring back：使回忆起来，带
回来、拿回来，使恢复。
3. Scientists continue to debate this issue.科学家们持续
地讨论这个问题。“debate”作动词“争论,辩论,讨论”讲,既能够
是不及物动词也能够是及物动词，作不及物动词时常与“about/
on/upon” 搭配。
练习：
A However, people who spend time thinking about their dreams believe that they are meaningful and useful.
B The final REM period may last as long as 45 minutes.
C People who are very aware of color when they are awake probably notice color more often in their dreams.
D Our most powerful dreams don’t happen during deep sleep.
E To learn to understand your dreams, think about what each part of the dream means to you or reminds you of.
F Sometimes, though, people suddenly remember a dream
later in the day or on another day.
第六篇 The Apgar Test
The baby was bom at 3：36 p. m. At 3：37，she scored 4
out of 10 on her first test. At 3：41，she scored 8 out of 10. The doctor was glad.
Another baby, bom at 8：24 p. m.，scored 3 out of 10 on
his first test He scored 4 out of 10 on his second test. He
took another test at 8：34 and scored 5. 1 He called for
help1.(环球网校2020年职称英语理工类教材新增文章汇总)
These newborn babies took a test called the Apgar test. This test helps doctors diagnose problems. 2 Most babies take two tests. The first is at 1 minute after birth, and the second is at 5 minutes after birth. If a baby’s score at 5 minutes is less than 6，the baby takes another test at 10 minutes after birth.
The Apgar test is not an intelligence test. It’s a test that shows a baby’s health right after it is bom. The A pgar test measures things such as a baby’s color, heart rate, and breathing. The test has five parts, and the score for each part can be 0，1，or 2. 3
A doctor named Virginia Apgar developed the test. Apgar went to medical school at Columbia University in New York City in 1929. She faced many challenges because she was the first woman in the program. However, she was one of the best students in her class. After medical school，she started treating patients2.
Apgar also became a researcher in anesthesiology, a new topic in medicine at the time3. During her studies, she learned how to give patients anesthesia. 4
In the 1940s，many women started to have anesthesia when they gave birth. Apgar had a question： How does anesthesia affect newborn babies? In 1949, when Apgar was a professor at Columbia’s medical school, she created her simple test. She wrote a paper about her methods in 1953. Soon after, people started using the Apgar test around the world.
In her work, Apgar saw that many newborns had problems. She wanted to help these babies survive. She stopped practicing medicine in 1959，and she went back to school to get a master’s degree in public health. 5
Today，the Apgar test is still used all over the world. Newborn babies don’t know it, but Virginia Apg ar is a very important person in the first few minutes of their lives.

第七篇 lee Cream Taster Has Sweet Job
John Harrison has what must be the most wanted job in the United States. He’s the official taster for Edy’s Grand Ice Cream, one of the nation’s bes t-selling brands. Harrison’s taste buds are insured for $1 million. 1 And when he isn’t doing that, he travels, buying Edy’s in supermarkets all
over the country so that he can check for perfect appearance，texture, and flavor.
After I interviewed Harrison, I realized that the life of an ice cream taster isn’t all Cookies ’n Cream 一 a flavor that* he invented, by the way. No, it’s extremely hard work, which requires discipline and selflessness.
For one thing，he doesn’t swallow on the job. Like a coffee taster, Harrison spits. Using a gold spoon to avoid “off’ flavors, he takes a small bite and moves it around in his mouth to introduce it to all 9,000 or so taste buds. 2 Then he breathes in gently to bring the aroma up through the back of his nose. Each step helps Harrison evaluate whether
the ice cream has a good balance of dairy, sweetness, and added ingredients 一 the three-flavor components of ice cream. Then, even if the ice cream tastes heavenly, he puts it into
a trash can. A full stomach makes it, impossible to judge the quality of the flavors.
During the workweek, Harrison told me that he has to make other sacrifices, too： no onions, garlic, or spicy food, and
no caffeine. Caffeine will block the taste buds, he says, so his breakfast is a cup of herbal tea. 3
Harrison’s family has been in the ice cream business in one way or another1 for four generations, so Harrison has spent his entire life with it2. However, he has never lost his love for its cold, creamy sweetness. 4 On these occasions3，he does swallow, and he eats about a quart (0.95 liters) each week. By comparison4, the average person in the United States eats 23.2 quarts (21. 96 liters) of ice cream and other frozen dairy products each year.(环球网校2020年职称英语理工类教材新增文章汇总)
Edy，s ice cream is available in dozens of flavors. So what flavor does the best-trained ice-cream taster in the country prefer? Vanilla! In fact, vanilla is the best-selling variety in the United States.
5 “It，s a very complex flavor，，，Harrison says.

F He gets to sample 60 ice creams a day at Edy，s headquarters in Oakland, California.
第十四篇 Primer on Smell
In addition to bringing out1 the flavor of food, what
does the sense of smell do for us?
Smell “gives us information about place, about where we are，” says Randall Reed, a Johns Hopkins University
professor whose specialty is the sense of smell. 1 “Whe ther we realize it or not, we collect a lot of information about who is around us based on smell，，，says Reed.
Even at a distance, odors can warn us of2 trouble —
spoiled food, leaking gas, or fire. “It’s a great alert，，，offers Donald Leopold, a doctor at Johns Hopkins. For example, if something in the oven is burning, everyone in the house knows it.
With just a simple scent, smell can also evoke very intense emotion. Let’s say, for example，that the smell is purple petunias. 2 Now let’s imagine that your mother died when you were three, and she used to have a flower garden. You wouldn’t need to ident ify the smell or to have conscious memories of your mother or her garden. You would feel sad as soon as you smelled that spicy odor.
Compared with3 animals, how well do people detect smelts?(环球网校2020年职称英语理工类教材新增文章汇总)
That depends on what you mean by “how well”. We are low on receptor cells ： current estimates say that humans have roughly five million smell-receptor cells，about as many as a mouse.
Reed says that, across species, there is a relatively good correlation between the number of receptor cells and how strong the sense of smell is. “You can hardly find the olfactory bulb in a
human brain it’s a pea-sized object. In a mouse, it，s a little bigger. It’s bean-sized in a rat, about
the size of your little finger in a rabbit, and the size of your thumb in a bloodhound.”
Does that mean that our sense of smell is not very acute?
Not exactly. While we may not have the olfactory range of other creatures, the receptors we do have are as sensitive as those of any animal. 4 A trained “nose，，，such as that of a professional in the perfume business, can name and distinguish about 10,000 odors. Reed says that a perfume
expert can sniff a modem scent that has a hundred different odorants in it, go into the lab, and list the ingredients. “In a modest amount of time, he comes back with what to you or me would smell like a perfect imitation of that perfume. It’s amazing.”
What happens to4 our sense of smell as we age?
Many people continue to have good olfactory function as they get older. 5 Leopold says that smell is generally highest in childhood, stays the same from the teens through the 50s, and drops starting at about 60 for women and 65 for men. “The average 80-year-old is only able to smell things half as well as the average 20-year-old,says Leopold.

理工C阅读理解新增文章 第九篇An Essential Scientific Process All life on the earth depends upon green plants. Using sunlight, the plants produce their own food. Then animals feed upon the plants. They take in the nutrients the plants have made and stored. But that’s not all. Sunlight also helps a plant produce oxygen. Some of the oxygen is used by the plant, but a plant usually produces more oxygen than it uses. The excess oxygen is necessary for animals and other organisms to live. The process of changing light into food and oxygen is called photosynthesis. Besides light energy from the sun, plants also use water and carbon dioxide. The water gets to the plant through its roots. The carbon dioxide enters the leaves through tiny openings called stomata. The carbon dioxide travels to chloroplasts, special cells in the bodies of green plants. This is where photosynthesis takes place. Chloroplasts contain the chlorophylls that give plants their green color. The chlorophylls are the molecules that trap light energy. The trapped light energy changes water and carbon dioxide to produce oxygen and a simple sugar called glucose. Carbon dioxide and oxygen move into and out of the stomata. Water vapor also moves out of the stomata. More than 90 percent of water a plant takes in through its roots escapes through the stomata. During the daytime, the stomata of most plants are open. This allows carbon dioxide to enter the leaves for photosynthesis. As night falls, carbon dioxide is not needed. The stomata of most plants close. Water loss stops. If photosynthesis ceased, there would be little food or other organic matter on the earth. Most organisms would disappear. The earth’s atmosphere would no longer contain oxygen. Photosynthesis is essential for life on our planet. 词汇： nutrient n.营养物 organism n.生物体，有机体 carbon dioxide n.二氧化碳 chloroplast n.叶绿体 molecule n.分子 vapor n.水蒸气 oxygen n.氧气 photosynthesis n.光合作用 chlorophyll n.叶绿素 glucose n.葡萄糖 cease v.停止 注释： 1．Then animals feed upon the plants.动物以植物为食。 练习： 1．In the first paragraph，the word “excess” means Aheavy.

Some psychologists say that this nighttime activity of the mind has no special meaning. Others，however， think that dreams are an important part of our lives. In fact, many experts believe that dreams can tell us about a person’s mind and emotions. Before modern times, many people thought that dreams contained messages from God. It was only in the twentieth century that people started to study dreams in a scientific way. The Austrian psychologist, Sigmund Freud，was probably the first person to study dreams scientifically. In his famous book, The interpretation of Dreams (1900), Freud wrote that dreams are an expression of a person’s wishes. He believed that dreams allow people to express the feelings, thoughts, and fears that they are afraid to express in real life. 1 The Swiss psychiatrist Carl Jung，however，had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer. He thought people could learn more about themselves by

M Climate Change Poses Major Risks for Unprepared Cities A new examination of urban policies has been carried out recently by Patricia Romero Lankao. She is a sociologist specializing in climate change and urban development. She warns that many of the world’s fast -growing urban areas, especially in developing countries, will likely1 suffer from the impacts of changing climate. Her work also concludes that most cities are failing to reduce emissions of carbon dioxide and other greenhouse gases. These gases are known to affect the atmosphere. “Climate change is a deeply local issue and poses profound threats to the growing cities of the world,” says Romero Lankao. “But too few cities are developing effective strategies to protect their residents. ” Cities are major sources of greenhouse gases. And urban populations are likely to be among those most severely affected by future climate change. Lankao’s findings3 highlight ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term benefits The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential threats associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat heavily paved cities more than surrounding areas. The impacts of such natural events can be more serious in an urban environment. For example, a prolonged heat wave can increase existing levels of air pollution, causing widespread health problems. Poorer neighborhoods that may lack basic facilities such as drinking water or a dependable network of roads, are especially vulnerable to natural disasters. Many residents in poorer countries live in substandard housing without access to reliable drinking water, roads and basic services. Local governments,therefore,should take measures to protect their residents. “Unfortunately, they tend to move towards rhetoric rather than meaningful responses,” Romero Lankao writes. “They don’t impose construction standards that could reduce heating and air conditioning needs. They don’t emphasize mass transit and reduce automobile, use. In fact, many local governments are taking a hands-off approach.” Thus, she urges them to change their idle policies and to take strong steps to prevent the harmful effects of’ climate change on cities. Free Statins With Fast Food Could Neutralize Heart Risk Fast food outlets could provide statin drugs free of charge so that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London suggest in a new study. Statins reduce the amount of unhealthy “LDL ” cholesterol in the blood. A wealth of trial data4 has proven them to be highly effective at lowering a person ’s heart attack risk In a paper published in the American Journal of Cardiology, Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is enough to offset the increase in heart attack risk from eating a cheeseburger and drinking a milkshake. Dr Francis, from the National Heart and Lung Institute at Imperial College London, who is the senior author of the study, said: “Statins don ’t cut out all of the unhealthy effects of cheeseburgers and French fries. It ’s better to avoid fatty food altogeth er. But we’ve worked out that in terms of your possibility of having a heart attack, taking a statin can reduce your risk to more or less the same degree as a fast food meal increases it. ” It ’s ironic that people are free to take as many unhealthy condiments in fast food outlets as they like, but statins, which are beneficial to heart health, have to be prescribed. It makes sense to make risk-reducing statins available just as easily as the unhealthy condiments that are provided free of charge. It would cost less than 5 pence per customer —— not much different to a sachet of sugar, “ Dr Francis said. When people engage in risky behaviours like driving or smoking, they ’re encouraged to take measures that lower their risk, like wearing a seatbelt or choosing cigarettes with filters. Taking a stain is a rational way of lowering some of the risks of eating a fatty meal. Better Solar Energy Systems: More Heat, More Light Solar photovoltaic thermal energy systems, or PVTs, generate both heat and electricity, but until now they haven’t been very good at the heat-generating part compared to a stand-alone solar thermal collector. That’s because they operate at low temperatures to cool crystalline silicon solar cells, which lets the silicon generate more electricity but isn’t a very efficient way to gather heat. That ’s a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And it ，s also a space problem ：photovoltaic cells can take up all the space on the roof, leaving little room for thermal applications. In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has devised a solution in the form of a better PVT made with a different kind of silicon. His research collaborators are Kunal Girotra from ThinSilicon in California and Michael Pathak and Stephen Harrison from Queen’s Universi ty, Canada." Most solar panels are made with crystalline silicon ， but you can also make solar cells out of amorphous silicon,commonly known as thin-film silicon. They don ’t create as much electricity, but they are lighter, flexible, and cheaper. And, because they require much less silicon, they have a greener footprint. Unfortunately ，thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.
第五篇Tracking Down HIV In the summer of 1980, a patient had a strange purplish spot removed from below his ear. It was Kaposi’s sarcoma, a rare form of skin cancer. This patient also had lymph node swelling and exhaustion. In November 1980, a Los Angeles immunologist examined a young man who had diseases linked to immune system malfunctions. The doctor had a T-cell count taken of the patient’s blood. T-cells are a type of white blood cell that plays a key role1 in immune responses. The patient had no helper T-cells. By the end of 1980, 55 Americans were diagnosed with infections related to immune system breakdown; four had died. A year later the death toll was 74. Intravenous drug users had T-cell abnormalities. People who had received blood transfusions showed symptoms of immune system breakdown. By July 1982, 471 cases of the disease, now called Acquired Immune Deficiency Syndrome (AIDS), had been reported; 184 people had died. In April 1984, American virologist Dr. Robert Gallo isolated the pathogen, or disease producer, responsible for2 AIDS. He called it HTLV-III. In Paris, Dr. Luc Montagnier identified a virus he called LAV. An international panel of scientists determined that both men had found the same virus. It became known as Human Immunodeficiency virus (HIV). Blood banks began screening for HTV in 1985, but by then about 29,000 people had been infected through blood transfusions. Some 12,000 hemophiliacs had contracted HIV through blood-clotting products. By 1995, 477,900 Americans had AIDS; 295,500 had died.
写在最前面的关于30分题+15分 1. +表示A级文章；*表示B即文章；其他为C级文章，考哪一级就看哪一级的内容，别的级别的题目完全不用看。 2. 每个级别新增阅读理解2篇完型填空2篇（今年以前完形填空只新增一篇），考试的时候，这两篇阅读理解必考一篇，文章完全一样，但是问题及答案不一定完全一样，所以仅仅记住答案是不可靠的，一定要结合后面的翻译把这篇文章看懂。那么这里5道题目15分必定能拿到。 然后完型填空，先说今年以前，只新增一篇完型填空，这篇完型填空必考，只是留空的位置不会完全一样，大约有40%左右的留空位置是一样，所以光背答案是没得用的，一定要把文章看熟。当然今年由于每个级别新增了2篇完型填空，那么考试的时候肯定也是2选1考一篇。这里15道题15分也很容易能拿到。 3. 词汇有15道题，替换同义词，找本字典翻翻，这15分也不难，至少12分能拿到吧。其他的题能拿多少分就看各位的英语底子了。做最坏的打算，剩下的题目还有55分，按瞎蒙25%的概率能拿到13.75分，加上前面的45分大约也有58分左右，所以要完全靠瞎蒙的朋友考试前多扶扶老奶奶过马路，多积累点人品吧。 4. 以上只是投机取巧的方法，各位有时间的话还是花点时间复习下，但是考前一定要把新增的题目掌握好，就算英语
底子好的朋友也起码可以节约不少考试时间。 5. 本人职称英语A\B\C级都是这样考过的，每年的规律都是一样的。从客观角度说，每年的职称英语考试书都不便宜，新增的内容也不多，如果新增的东西里面没有价值，那么那本书还有谁买？那本书可是考试中心出的，亲！ 最后，祝大家考试顺利！

School Lunch Research has shown that over half the children in Britain who take their own lunches to school do not eat properly in the middle of the day.In Britain schools have to provide meals at lunchtime.Children can choose to bring their own food or have lunch at the school canteen. One shocking finding of this research is that school meals are much healthier than lunches prepared by parents.There are strict standards for the preparation of school meals,which have to include one portion of fruit and one of vegetables,as well as meat,a dairy item and starchy food like bread or pasta.Lunchboxes examined by researchers contained sweet drinks,crisps and chocolate bars.Children consume twice as much sugar as they should at lunch time. The research will provide a better understanding of why the percentage of overweight students in Britain has increased in the last decade.Unfortunately,the government cannot criticise parents,but it can remind them of the nutritional value of milk,fruit and vegetables.Small changes in their children’s diet can_affect their future health.Children can easily develop bad eating_habits at this age,and parents are the only ones who can prevent it.A Powerful Influence There can be no doubt at all that the Internet has made a huge difference1to our lives.Parents are worried that children spend too much time playing on the Internet,hardly ever doing anything else in their spare time.Naturally,parents are curious to find out why the Internet is so attractive,and they want to know if it can be harmful for their children.Should parents worry if their children are spending that much time staring at their computers? Obviously,if children are bent over their computers for hours,absorbed in some game,instead of doing their homework,then something is wrong.Parents and children could decide how much use the child should_make of the Internet,and the child should give his or her word that it won’t interfere with homework.If the child is not holding to this arrangement,the parent can take more drastic steps dealing with a child’s use of the Internet is not much different from negotiating any other sort of bargain about behaviour.Any parent who is_seriously alarmed about a child’s behaviour should make an appointment to discuss the matter with a teacher.Spending time in front of the screen does not necessarily affect a child’s performance at school.Even if a child is absolutely crazy about using the Internet,he or she is probably just going through a phase,and in a few months there will be something else to worry about!The Old Gate In the Middle Ages the vast majority of European cities had walls around them.This was partly for defensive reasons but another factor was the need to keep out anyone regarded as undesirable,like people with contagious diseases.The Old City of London gates were all demolished by the end of the 18th century.The last of London’s gates was removed a century ago,but by a stroke of luck,it was never destroyed. This gate is,in actual fact,not called a gate at all;its name is Temple Bar,and it marked the boundary between the Old City of London and Westminster.In 1878the Council of London took the Bar down,numbered the stones and put the gate in storage because its design was unfashionable it was expensive to maintain and it was blocking the traffic. The Temple Bar Trust was set up in the 1970’s with the intention of returning the gate home.The aim of the Trust is the preservation of the nation’s architectural heritage.Transporting the gate will mean physically pulling it down,stone by stone,removing and rebuilding it near St Paul’s Cathedral.Most of the facade of the gate will probably be replaced,though there is a good chance that the basic structure will be sound.The hardest job of all,however,will be to recreate the statues of the monarchs that once stood on top of the gate.Family History In an age when technology is developing faster than ever before,many people are being attracted to the idea of looking back into the past.One way they can do this is by investigating their own family history.They can try to find out more about where their families came from and what they did.This is now a fast-growing hobby,especially in countries with a fairly short history,like Australia and the United States. It is one thing to spend some time going through a book on family history and to take the decision to investigate your own family’s past.It is quite another to carry out the research work successfully.It is easy to set about it in a disorganized way and_cause yourself many problems which could have been avoided with a little forward planning. If your own family stories tell you that you are connected with a famous character,whether hero or criminal,do not let this idea take over your research.Just treat it as an interesting possibility.A simple system for collecting and storing your information will be adequate to start with;a more complex one may only get in your way.The most important thing,though,is to get started.Who knows what you might find? Helen and Martin With a thoughtful sigh,Helen turned away from the window and walked back to her favourite armchair.Would her brother never arrive?For a brief moment,she wondered if she really cared that much. Over the years Helen had given up waiting for Martin to take an interest in her.Her feelings for him had gradually weakened until now,as she sat waiting for him,she experienced no more than a sister’s curiosity to see what had become of her brother. Almost without warning,Martin had lost his job with a busy publishing company after spending the last eight years in New York as a key figure in the US office.Somehow the two of them hadn’t bothered to keep in touch and,left alone,Helen had slowly found
