Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in your mouth. First gently bite the edges of your tongue with your teeth. Or, press your entire tongue to the bottom of your mouth and hold it there until the saliva flow. Or you can imagine that you are slicing a big juicy lemon and sucking the juice.
Before you begin your talk, be kind to your voice. Avoid milk or creamy drinks that coat your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.
If you sense that you are losing your voice, stop talking completely. Save your voice for your speech. You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice. If you need to see a doctor, perhaps you can get some advice from a professional singer. In the meantime, do not even talk in a low voice.
What about drinking alcohol to wet your throat? I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence. The second drink gives you even more confidence. Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work together properly. Save the alcohol until after you finish speaking.
Perhaps you want to accept the advice, but you may wonder if you can change the habits of a lifetime. Of course you can. Goethe, who lived before indoor skating rinks or swimming pools, said, " we learn to skate in the summer and swim in the winter\'. Take this message to heart and give yourself time to develop your new habits. If you are willing to change, you will soon be able to say that you will never forget these techniques because they became a part of your body.

1Voluntary learning in organized courses by mature men and women is called adult education. Such education is offered to make people able to enlarge and interpret their experience as adults. Adults may want to study something which they missed in earlier schooling, get new skills or job training, find out about new technological developments, seek better self-understanding, or develop new talents and skills.
2This kind of education may be in the form of self-study with proper guidance through the use of libraries, correspondence courses, or broadcasting. It may also be acquired collectively in schools and colleges, study groups, workshops, clubs and professional associations.
3Modern adult education for large numbers of people started in the 18th and 19th centuries with the rise of the Industrial Revolution. Great economic and social changes were taking place: people were moving from rural areas to cities; new types of work were being created in an expanding factory system. These and other factors produced a need for further education and re-education of adults.
4The earliest programs of organized adult education arose in Great Britain in the 1790s, with the founding of an adult school in Nottingham and a mechanics\' institution in Glasgow. Benjamin Franklin and some friends found the earliest adult education institution in the U.S. in Philadelphia in 1727.
5People recognize that continued learning is necessary for most forms of employment today. For example, parts of the adult population in many countries find it necessary to take part in retraining programs at work or even to learn completely new jobs. Adult education programs are springing up constantly to meet these and other needs.

Medical journals are publications that report medical information to physicians and other health professionals．
In the past，these journals were available only in print．With the development of electronic publishing，many medical journals now have Web sites on the Internet，and some journals publish only online．A few medical journals，like the Journal of the American Medical Association，are considered general medical journals because they cover many fields of medicine．Most medical journals are specialty journals that focus on a particular area of medicine．
Medical journals publish many types of articles．Research articles report the results of research studies on a range of topics varying from the basic mechanisms of diseases to clinical trials that compare outcomes of different treatments．Review articles summarize and analyze the information available on a specific topic based on a careful search of the medical literature．
Because the results of individual research studies can be affected by many factors，combining results from different studies on the same topic can be helpful in reaching conclusions about the scientific evidence for preventing，diagnosing or treating a particular disease．Case conferences and case reports may be published in medical journals to educate physicians about particular illnesses and how to treat at them．Editorials in medical journals are short essays that express the views of the authors，often regarding a research or review article published in the same issue．
Editorials provide perspective on how the current article fits with other information on the same topic．Letters to the editor provide a way for readers of the medical journal to express comments， questions or criticisms about articles published in that journal．
1．The main readers of medical journals are
A)the general public．

Adaptation of Living Things
Certain animals and plants develop characteristics that help them cope with their environment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter, in providing protection, and in producing and protecting the young. That results in the evolution of more and more organisms that are better fitted to their environments.
Each living thing is adapted to its way of life in a general way, but each is adapted especially to its own distinct class. A plant, for example, depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the sun\'s energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are special adaptations that only certain kinds of plants have.
Many animals have adaptations that help them escape from their enemies. Some insects are hidden by their body color or shape, and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the ability to remain completely still when an enemy is near.
Organisms have a great variety of ways of adapting. They may adapt in their structure, function, and genetics; in their development and production of the young; and in other respects. An organism may create its won environment, as do warm-blooded mammals, which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather.Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that, if conditions change, it finds it difficult or impossible to readapt to the new conditions.

A. help others of their kind get food, shelter and other things needed.
