Using HIV Virus to Cure Cancer
Scientists are planning to use human immunodeficiency(免疫缺陷)virus(HIV)，one of mankind's most feared viruses，as a carrier of genes which can fight cancer and a range of diseases that cannot be cured.The experts say HIV has an almost perfect ability to avoid the body's immune(免疫的)defenses，making it ideal for carrying replacement genes into patients' bodies，according to the Observer.
A team at the California-based Salk Institute，one of the world's leading research centers on biological sciences，has created a special new breed of HIV and has started negotiations with the U.S.Food and Drug Administration(FDA)to begin clinical gene therapy(治疗)trials this year.The first trials are expected to involve patients suffering from cancers that cannot be cured by surgery although project leader Professor Inder Verma said the HIV technique would have"far wider applications".
The plan remains very likely to cause controversy since it involves making use of a virus which has caused more than22 million deaths around the world in the past two decades.Verma said that the idea of using HIV for a beneficial purpose was "shocking"but the fierce nature of HIV had disappeared by
having all six of the potentially deadly genes removed.
Illnesses such as various cancers are caused when a gene in a patient's body fails to work properly.In the past two years，breakthroughs in genetics(遗传学)have led gene therapy scientists to try and replace the genes that do not function normally.
Unfortunately，the body's immune defenses have been known to attack the modified genes and make them lose their effects before they can start their task and progress in the field has been held up by the lack of a suitable carrier.'
The HIV virus has the ability to escape from，and.then destroy，the immune defense cells designed to protect our bodies and this makes it attractive to scientists as a way of secretly conveying replacement genes into patients'bodies.

Inhalable Water Droplets
You think that the biggest threat to your health when taking a shower comes from slipping on a bar of soap?Well,guess again.
Preliminary studies by engineers at the University of Cincinnati and the Oak Ridge Institute for science and education,also in Cincinnati,indicate that some water-saving shower nozzles produce water droplets so small they can be inhaled,exposing anyone using the shower to several different health hazards.
Using a device called an optical particle counter the researchers tested a number of shower nozzles,both of adjustable and fix-spray styles.They found that some products create droplets less than10microns in diameter-small enough to be inhaled.That\'s problem,the researchers theorise, because the water may contain trace of chemicals used by treatment facilities to kill microbes and bacteria in the water.
These organic compounds are relatively safe to take in by drinking,but may not be safe to inhale.
Another threat may be possible as well.Previous research has shown that the droplets can contain microbes that live inside the warm,wet interior of shower nozzles.When the faucet is turn on,these microbes are swept out through the nozzles. If these droplets are inhaled,the microbes could pose a threat to people who are with asthma and other respiratory problems.
All of this doesn't mean you should skip your morning shower just yet.More research is needed,cautious oak ridge institute scientist Virendra Sethi says,before anyone can determine just how serious—or insignificant—these health risks may be. Moreover,not all water-conserving nozzles produce inhalable droplets."It all depends on the design of the nozzle,"says Sethi.Right now there is no way for consumers to know which nozzle produce these tiny drops."We are working to develop specifications for shower head designs that would not generate droplets in the inhalable size range,"he adds.

Riches and Romance From France’s Wine Harvest
September is harvest time.And with bunches of grapes swinging(摇摆)in the wind，the vineyards of southern France are getting ready to celebrate it.
The yearly wine festival is held in honour of Bacchus，the Roman god of wine.It's a fun time with parties，music，dancing，big meals and，of course，lots of wine.
French wine-making began more than2,500years ago.The world’s oldest type of vine grows in France and always produces a good quality wine.Today France produces one-fifth of the world’s wine，and some of the most famous varieties.
The top wine-producing areas are Bordeaux，Burgundy and the Loire Valley.Champagne，a drink used in celebrations，is named after the place where sparkling(有汽泡的)wine was first produced in1700.
Wine is made from the juice of freshly picked grapes.It is the sugars that turn into alcohol.
Traditionally，people used to take off their shoes and crush the grapes with their bare feet to bring out the juice.Nowadays，this practice is usually carried out by machines.
Each wine producing region has its own character，based on its type of grapes and soil.
The taste of wine changes with time.Until1850，all French
champagne was sweet.Now，both wine and champagne taste slightly bitter.
The drink has always been linked with riches，romance and nobleness.Yet the French think of it in more ordinary terms.
They believe it makes daily living easier,less hurried and with fewer problems.
“All its links are with times when people are at their best;with relaxation，happiness，long slow meals and the free flow of ideas,”wrote wine expert Hugh Johnson.

Thanksgiving with the Watsons
People came to America from every country in the world and brought the traditions of their ancestors with them.Thus，most American traditions are not really American.But Thanksgiving (感恩节)is different because it started in America.So it is a truly American tradition.
Life provides many good and bad things.Every year，in November，Thanksgiving Day reminds us of the good things in life，and people are thankful.On this day people usually eat turkey and great quantities of other foods.Jesse has decided to spend Thanksgiving with David and Elizabeth Watson because he likes them，and because he cannot go to his parents'home in Chicago.
Elizabeth's nickname(昵称)is Betty，and people usually call her that.She is the secretary of Jesse's boss.Jesse got
to know the Watsons two years ago and he and Dave have become good friends.Sometimes they go fishing or to a ball game together.
The Watsons live in a small apartment in a suburb of New York City.The offices where Betty works are in downtown New York，and she has to take a bus and two subway trains to go to work every day.It takes her about one hour to get there. She finds the trip boring and tiring.She wants to stay home in order to take care of the family and enjoy the children.The Watsons have three children.Their daughter Sue is in the fourth grade and their son Paul is in the second grade.They also have a two-year-old daughter，Ann.
The children like Jesse;he is their hero.He tells them stories about foreign countries，about Africa and China，about the Pacific and Japan;he has never even seen most of these countries.He knows about fast cars and new inventions.The Watson children think that Jesse is full of adventures;he is fascinating to them.Frequently he takes them to the park and joins them in their games.
Today Jesse brought Sue a record of her favorite music，because she has a new record player.He also brought Paul a toy truck and Ann a plastic(塑料)book with bright pictures，and
Betty a bunch of flowers.Betty cooked a nice turkey，and they all ate too much.After dinner the children wanted to go out to the park with Jesse.But they had to stay home，because it was https://www.doczj.com/doc/4a17471796.html,ter，Dave and Jesse sat down in front of the TV to watch a football game.

A Pay Rise or Not?
"Unless I get a rise，I'll have a talk with the boss，Henry Manley，"George Strong said to himself.George liked his job and he liked the town he lived in，but his wife kept telling him that his pay was not enough to meet the needs of the family. That was why he was thinking of taking a job in Birmingham，a nearby city，about50miles away.He had been offered a job in a factory there，and the pay was far better.
George lived in Wyeford，a medium-sized town.He really liked the place and didn't like the idea of moving somewhere else，but if he took the job in Birmingham，he would have to move his family there.
Henry Manley was the manager of a small company manufacturing electric motors.The company was in deep trouble because，among other reasons，the Japanese were selling such things at very low prices.As a result，Manley had to cut his own prices and profits as well.Otherwise he would not get any orders at all.Even then，orders were still not coming in fast enough，so that there was no money for raises(加工资)for his workers Somehow，he had to struggle along and keep his best workers as well.He sighed.Just then the phone rang.
His secretary told him that George Strong wanted to see him
as soon as possible.Manley sighed again.He could guess what it was about.George Strong was a very young engineer.The company had no future unless it could attract and keep men like him Manley rubbed his forehead(前额);his problems seemed endless.

2020年职称英语考试模拟试题及答案（六） Farmers‘ markets Charlotte Hollins knows she faces a battle. The 23-year- old British farmer and her 21-year-old brother Ben are fighting to save the farm from developers that their father worked on since he was 14._____(46) “You don’t often get a day off. Supermarkets put a lot of pressure on farmers to keep price down. With fewer people working on farms it can be isolating，” she said. “There is a high rate of suicide and farming will never make you rich!” Oliver Robinson，25， grew up on a farm in Yorkshire.____(47)“I‘m sure dad hoped I’d stay，” he said. “I guess it‘s a nice ，straightforward life， but it doesn’t appeal. For young， ambitious people， farm life would be a hard world.” For Robinson，farming doesn‘t offer much “in terms of money or lifestyle.” Hollins agrees that economics stops people from pursuing farming rewards：“providing for a vital human need，while working outdoors with nature.” Farming is a big political issue in the UK.____(48) The 2001 foot and mouth crisis closed thousands of farms， stopped meat exports，and raised public consciousness of troubles in UK farming. Jamie Oliver’s 2005 campaign to get children to eat healthily also highlighted the issue. This national concern spells(带来) hope for farmers competing with powerful supermarkets.____(49)
2020年职称英语考试综合类阅读判断练习及答案(10) Disease, Diagnosis, Treatment and Prevention Disease may be defined as the abnormal state in which part or all of the body is not properly adjusted or is not capable of carrying on all its required functions. There are marked variations in the extent of the disease and in its effect on the person. In order to treat a disease, the doctor obviously must first determine the nature of the illness–this is, make a diagnosis. A diagnosis is the conclusion drawn from a number of facts put together. The doctor must know the symptoms, which are the changes body function felt by the patient and the signs(also called objective symptoms) which the doctor himself can observe. Sometimes a characteristic group of signs(or symptoms)accompanied a given disease. Such a group is called a syndrome. Frequently certain laboratory tests are performed and the results evaluated by the physician in making his diagnosis. Although nurses do not diagnose, they play an extremely valuable role in this process by observing closely for signs, encouraging the patient to talk about himself and his symptoms, and then reporting this information to the doctor. Once the patience's disorder is known, the doctor prescribes a course of treatment, also referred to as therapy. Many measures in this course of treatment are carried out by the nurse under the physician's orders. In recent years physicians, nurses and other health workers have taken on increasing responsibilities in

Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat Walls would "radiate light" and "change color with the push of a button." Food would be replaced by pills. School would be taught "by electrical impulse while we sleep." Cars would have radar. Does this sound like the year 2000? Actually, the article was written in 1958 and the question was, "what will life be like in 1978?" The future is much too important to simply guess about, the way the high school students did, so experts are regularly asked to predict accurately. By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: Cities of the future would not be crowded, but would have space for farms and fields. People would travel to work in "airbuses", large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard of". Does that sound familiar? If the expert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982". If the professionals sometimes sound like high-school students, it's probably because future study is still a new field. But economic forecasting, or predicting what the economy will do, has been around for a long time. It should be accurate, and generally it is. But there have been some big market in the field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers. One forecaster knew that predictions about the future would always be subject to significant error. In 1957, H.J.Rand of the Rad corporation was asked about the year 2000, "Only one thing is certain," he answered. "Children born today will have reached the age of 43." 1. The high-school students' answers to "What would life be like in 1978?" sound A) accurate. B) imaginative. C) correct. D) foolish. 2. According to the writer, forecasting is fairly accurate in A) politics. B) science. C) sociology. D) economy. 3. Which of the following statements is not compatible with the writer's comment on future study?
