dear amy,
thank you for your letter.i am so glad to have a talk about your present situation with you.
people often miss their parents the first time they leave home.most people do have to leave home for higher education or employment.you cannot live with your parents forever.i think you should realize that present separation will help your academic development and your improvement of personal ability.
you need to make friends in your school,sharing ideas with your classmates who are physically closest to you now.maybe you will still miss your parents,but your new friends will bring happiness and joy to your new life.also i suggest you enjoy yourself by taking an active part in different kinds of activities in school.you will get much pleasure from it.
wish you happy every day.
faithfully yours,
editor

what we still don't know about aids?(艾滋病還有哪些未解之謎?)
in the 20 years since the first cases of aids were detected,scientists say they have learned more about this viral disease than any other.
yet peter piot,who directs the united nations aids program,and stefano vella of rome,president of the international aids society,and other experts say reviewing unanswered questions could prove useful as a measure of progress for aids and other diseases.
among the important broader scientific questions that remain:
1.why does aids predispose infected persons to certain types of cancer and infections?
a long-standing belief is that cancer cells constantly develop and are held in check by a healthy immune system.but aids has challenged that belief.people with aids are much more prone to certain cancers like non-hodgkins lymphomas and kaposi's sarcoma,but not to breast,colon and lung,the most common cancers in the united states.this pattern suggests that an impaired immune system,at least the type that occurs in aids,does not allow common cancers to develop.
