As of 1995,185 states had membership
2、in the general Assembly. Additionally, the Vatican, Switzerland, and the Palestine Liberation Organization have nonvoting observer status in the General Assembly. The General Assembly approves the UNs budget, acts with the Security Council to select the Secretary-general and judges of the Internatio
3、nal Court of Justice, and passes resolutions on issues ranging from self-determination and colonialism to womens rights and the global distribution of wealth. The General Assembly can meet and vote on any subject, unless the Security Council is dealing with it (or at least pretending to). However, i
4、ts decisions only carry moral forceunlike the Councils. Theyre not binding in international laws. But the Assembly votes are an important opinion poll on how and what the majority of the world thinks about issues. Important questions need a two-thirds vote of the Assembly to pass. The question of wh
5、at is an important question isnt important. Its decided by the delegates themselvesby a simple majority. Although the General Assembly has not recognized authority to enforce its conclusions on anything other than internal UN matters, it makes its viewpoints on issues that are brought before it is k
6、nown in one of the three ways. A General Assembly declaration is a broad statement of general principle such as the Universal Declaration of Human Rights, passed in 1948. Declarations are often put forward as an expression of an ideal, in practice they are regularly ignored. A General Assembly resol
7、ution is essentially a document that recommends that member states take a particular policy action. States claim sovereignty and make their own decisions as to whether they will follow a General Assembly resolution. In some cases, however, if many states implement a particular resolution, other stat
8、es that may not wish to act on the resolution may feel themselves pressured to do so anyway. At the very least, a resolution has the effect of legitimizing the policies of those states that wish to comply with the resolution. Finally, a General Assembly convention, or treaty, has two meanings. The m
9、ore comprehensive convention refers to multilateral treaties voted on by the General Assembly that, upon passage by the General Assembly, are carried back to the capitals of member states for ratification by whatever means each state uses domestically. In other cases, a General Assembly convention r

11、Mentioned 2.On Antibodies Substances foreign to the body, such as disease-causing bacteria and viruses and other infectious agents, are recognized by the body s immune system as invaders. Our natural defenses against these infectious agents are antibodies, proteins that seek out the antigens (抗原) an
12、d help destroy them. Antibodies have two very useful characteristics. First, they are extremely specific; that is, each antibody binds to and attacks one particular antigen. Second, some antibodies, once activated by the occurrence of a disease, continue to confer resistance against that disease. Cl
13、assic example are the antibodies to the childhood diseases of chickenpox(水痘) and measles. The second characteristic of antibodies makes it possible to develop vaccines. A vaccine (痘苗) is a preparation of killed or weakened bacteria or viruses that, when introduced into the body, stimulates the produ
14、ction of antibodies against the antigens it contains. It is the first trait of antibodies, their specificity, that makes monoclonal antibody technology so valuable. Not only can antibodies be used therapeutically(在治疗上), to protect against disease; they can also help to .diagnose a wide variety of il
15、lnesses, and can detect the presence of drugs, viral and bacterial products, and other unusual or abnormal substances in the blood. Given such a diversity of uses for these diseased-fighting substances, their production in pure quantities has long been the focus of scientific investigation. The conv
16、entional method was to inject a laboratory animal with an antigen and then, after antibodies had been formed, collect those antibodies from the blood serum(血清) (Antibody containing blood serum is called antiserum (抗血清). There are two problems with this method: It yields antiserum that contains undesired substances, and it provides a very small amount of usable antibody. Monoclonal antibody technology
