Nanotechnology uses matter at the level of mo1ecules and atoms .Researchers are finding different uses for particles with a length of one nanometer，or one—billionth of a meter．These include things like beauty products and dirt—resistant clothing． But one area where many experts believe nanotechnology holds great promise is medicine．
Last week， speakers at a program in Washington discussed using nanotechnology to improve health care in developing countries．The program took place at the Woodrow Wilson International Center for Scholars．Peter Singer at the University of Toronto says a nanotechnology called quantum dots could be used to confirm eases of malaria．He says it could offer a better way than the traditional process of looking at a person’s blood under a microscope．
In poor countries，this process is often not followed． As a result，sick people may get treated for malaria even if they do not have it． Such misuse of medicines can lead to drug resistance. Quantum dots are particles that give off light when activated． Researchers are studying ways to program them to identify diseases by lighting up in the presence of a targeted molecule．
Experts say nanotechnology shows promise not just for diagnosing diseases，but also for treating them. Piotr Grodzinski of the National Institutes 0f Health talked about how nanotechnology could make drugs more effective．He talked about cancer drugs already developed with nanotechnology．He says if a drug can target a cancer locally in the body，then mach less of it might be needed，and that means lower side effects．
Andrew Maynard is chief scientist for the Project on Emerging Nanotechnologies at the WoodrowWilson Center．He noted that Brazil，India，China and South Afrieca are currently doing nanotechnology research that could help poor countries． But he also noted that there is some risk in using nano—materials. He says nanometer—sized particles behave differently in the body and the environmentcompared to larger particles． Experts say more investment in research is needed to better understand these risks．

1 You depend on all the people closely around to give you the warm feeling of belongingness (归属) that you must have to feel secure. But, in fact, the members of all the groups to which you belong also depend on you to give that feeling to them. A person who shows that he wants everything for himself is bound (一定的) to be a lonely wolf.
2 The need for companionship is closely related to the need for a sense of belongingness. How sad and lonely your life would be if you had no one to share your feelings and experiences. You may take it for granted that there always will be people around to talk to and to do things with you and for you. The important point, however, is that keeping emotionally healthy does not depend so much upon having people around you as upon your ability to establish relationships that are satisfying both to you and to them.
3 Suppose you are in a crowd watching a football game. You don't know them. When the game is over, you will all go your separate ways. But just for a while you had a feeling of companionship, of sharing the feelings of others who were cheering for the team you wanted to win.
4 An experience of this kind gives the clue (线索) to what companionship really is. It depends upon emotional ties of sympathy, understanding, trust, and affection.Companions become friends when these ties are formed.
5 When you are thrown in a new circle of acquaintances (熟人), you may not know with whom you will make friends, but you can be sure that you will be able to establish friendships if you show that you really like people.
