     According to the American College of Obstetrics and Gynecology, pregnant women should not drink any form of alcohol. Pregnant women who think they have should be aware of the serious and negative effects alcohol on the development of the baby (fetus).  

     Alcohol is considered one of the most dangerous drugs for women during their pregnancy. Because alcohol is delivered quickly into the blood and passes quickly into the tissues and membranes, the human fetus is particularly vulnerable to its effects. The reality is that the negative effects on a fetus are so pronounced that babies born after exposure to alcohol are said to be suffering from fetal the syndrome. As a pregnant woman drinks alcohol, the alcohol is passed into her bloodstream almost simultaneously. Moreover, because the bloodstream of the fetus is inextricably tied to that of the mother, the alcohol passes directly into the bloodstream of the fetus as well. And, what is more, the concentration of alcohol in the fetus is exactly the same as in the mother.  

     For the mother, this concentration is not a problem because her liver can remove one ounce of alcohol from her system per hour. However, the fetus's liver is not completely developed (how developed it is depends on its stage of development). The rate at which it is able to eliminate the alcohol from the blood of the fetus is much slower. Eventually, the alcohol will be returned to the mother's system by passing across the placenta, but this process is slow. By the time this takes place, major neurological damage may have already occurred.  

     Research has shown that as little as one drink of alcohol can produce significant, irreversible damage to the fetus. Babies born after exposure to alcohol generally exhibit facial distortion, inability to concentrate, and difficulty in remembering. Simply speaking, it is imperative that pregnant women avoid alcohol.

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 35 to 42  

     Employees in many countries change jobs more often than previous generations of workers. They don't expect to find a job with a company that will take care of them for the rest their lives. But what is the cause of this trend? Is it a new economy, new ways of doing business, or the employees themselves? A more globalized economy has had effect on employment.  

     A large number of companies are now international, and one of them may decide that moving its offices from Germany to Poland, for example, is in its best interest. That means employees who live and work in Germany may be asked to relocate their families to a new country or be told that their jobs are simply eliminated.  

     Companies have also responded to economic pressures by restructuring for greater efficiency. This sort of change within a company usually means that unnecessary jobs are cut, or that fewer employees must do more work. In either case, some employees find themselves looking for new jobs. New technology has also had an impact on workplaces. The increasing use of personal computers has meant fewer jobs for office secretaries, as their former bosses do their own word processing and letter writing, and for travel agents, as more travelers make their own reservations online. Automation, including the use of robotic devices, has replaced workers in clothing factories, post offices, and telephone companies, to name just a few.  

     Besides these economic and technological reasons, today's employees are also responsible for more frequent job changes. Workers in the past were less likely to leave a company because they were dissatisfied with working conditions or because they didn't get along well with their fellow employees.  People today expect to enjoy their work and to get a high degree of personal satisfaction from what they do for a living.  

     Employees may also leave a job because they have learned all they can learn from their current job. Getting a new job means gaining new skills and making new contracts, and these skills and relationships could bring them a step closer to their dream job”, the one that is challenging, emotionally and financially rewarding, and preferably closer to home or their children's school.  

     Finally, companies start up and close down more quickly than they once did. Employees who suspect that their employer is not doing well may decide to start looking for a new position before the company closes its doors.
