关于盐酸普鲁卡因注射液的制备，以下描述不正确的是

A:盐酸为pH调节剂，控制pH值在2.5～3.5 B:氯化钠除调节等渗，还能增加溶液的稳定性 C:采用采用流通蒸气灭菌（100℃，30min） D:盐酸普鲁卡因在水中极易水解，继续发生脱羧、氧化作用，生成有色物质 E:铜、铁等金属离子能加速本品的分解，但光线对分解没有影响 F:普鲁卡因结构中含有芳伯氨基，故易被水解

Free Statins With Fast Food Could Neutralize Heart Risk

    Fast food outlets could¹ provide statin drugs free of     1     so that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London²     2      in a new

study．

    Statins reduce the      3      of unhealthy ”LDL” cholesterol³ in the blood. A wealth of trial data⁴ has proven them to be highly effective at lowering a person’s heart attack      4      .

    In a paper published in the American Journal of Cardiology⁵，Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is       5       to offset the increase in heart attack risk from       6       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 a11 of the       7      effects of cheeseburgers and French fries⁶．It’s better to avoid fatty food altogether．But we’ve worked out that in terms of your       8      of having a heart attack. Taking a statin can reduce your risk to more or less the same    9    as a fast food meal increases it.”  “It’s ironic that people are free to take as many unhealthv condiments in fast food outlets as they       10     , but statins, which are beneficial to heart health, have to be prescribed. It makes sense⁷ to make risk-reducing statins available just as easily as the unhealthy condiments that are   l 1    free of charge．It would cost less than 5 pence per    1 2     一not much different to a sachet of sugar⁸.” Dr Francis said．

   When people engage in risky behaviours like driving or smoking, they’re encouraged to take     13     that lower their risk, 1ike    14     a seatbelt or choosing cigarettes with filters. Taking a statin is a rational way of     1 5     some of the risks of eating a fatty meal．

Migrant Workers

　　In the past twenty years, there has been an increasing tendency for workers to move from one country to another.    1   some newly independent countries have understandably restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East¹,    2     increased oil incomes have enabled many countries to    3    outsiders to improve local facilities.    4     the Middle East has attracted oil-workers from the USAandEurope. It has brought in construction workers and technicians from many countries,     5     SouthKoreaandJapan.
　　In view of the difficult living and working conditions in theMiddle East,²it is not   6     that the pay is high to attract suitable workers. Many engineers and technicians can earn at least     7    money in theMiddle Eastas they can in their own country, and this is a major attraction. An allied benefit is the low taxation or complete lack of it.³ This increases the net amount of pay received by visiting workers and is very popular with them.
　　Sometimes a disadvantage has a compensating advantage.     8    the difficult living conditions often lead to increased friendship when workers have to depend on each other     9    safety and comfort.     10    , many migrant workers can save large sums of money partly     11    the lack of entertainment facilities. The work is often complex and full of problems but this merely presents greater challenge engineers who prefer to find solutions     12    problems rather than do routine work in their home country.
　　One major problem which     13    migrant workers in theMiddle Eastis that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents.     14    , migrant workers accept this disadvantage, along with others, because of the     15     financial benefits which they receive.

Dreams

　　Everyone can dream. Indeed, everyone does dream. Those who    1    that they never dream at all actually dream    2    as frequently as the rest of us,    3    they may not remember anything about it. Even those of us who are perfectly     4     of dreaming night    5    night very seldom remember those dreams in    6    detail but¹ merely retain an untidy mixture of seemingly unrelated impressions. Dreams are not simply visual-we dream with all our    7    , so that we appear to experience sound, touch, smell, and taste.
　　One of the world’s oldest    8    written documents is the Egyptian Book of Dreams. This volume is about five thousand years old, so you can    9    that dreams were believed to have a special significance even then. Many ancient civilizations believed that you    10    never wake a sleeping person as, during sleep, the soul had left the body and might not be able to return     11     time if the sleeper were suddenly    12    .
　　From ancient times to the present²    13    , people have been   14    attempts to interpret dreams and to explain their significance. There are many books available on the subject of dream interpretation, although unfortunately there are almost as many meanings for a particular dream    15     there are books.

frequently /"friːkwəntlɪ/ adv.频繁地，经常地；时常，屡次
