        Latest data shows an estimated 39.5 million people around the world are living with HIV, the virus

that causes AIDS. According to the report, this means every eight seconds somebody in the world is

infected with HIV, resulting in 11,000 people becoming newly infected every day.

        The director of UNAIDS, Peter Piot, says most of the new infections, nearly two-thirds, are in

Sub-Saharan Africa. But, the biggest increases are in Eastern Europe and Central Asia, where infection

rates have risen by more than 50 percent since 2004. He says 2.9 million people died from AIDS-related

illnesses this year, the highest number ever.

        UNAIDS senior epidemiologist(流行病学家), Karen Stanecki, says infections are rising in countries

where HIV prevention programs have not adapted to the changing nature of the epidemics(流行病).  

Stanecki noted,"In Thailand, one of our past success stories, a large percentage of new HIV infections

are occurring in people considered to be low risk. One third of new infections are among married women."

         It says data shows increased use of condoms has resulted in drops in HIV prevalence(流行) among

young people between 2000 and 2005 in a number of African countries, including Botswana, Kenya and

Zimbabwe. Nevertheless, the report notes young people between the ages of 15 and 24 account for 40

percent of new HIV infections. It finds the risk behavior, such as injecting drug use, homosexuals, is a

factor of concern in many regions of the world, especially in Asia, Eastern Europe and Latin America.

        The report notes the emergence (出现) of injecting drug use as a factor of HIV in Kenya, Tanzania,

Nigeria and South Africa is a recent development in Sub-Saharan Africa.

一对表现型正常的夫妇,第一胎生了一个患白化病(由隐性基因控制)的儿子,那么第二胎还是生白化病儿子的几率是()A.1/4B.1/8C.1/2D.1/3

白化病基因用A、a表示,表现型正常的夫妇生了一个患白化病的儿子,说明这对夫妇都是白化病基因的携带者(AA.,根据基因的分离定律,Aa×Aa→1AA:2Aa:1aa,即第二胎还是生白化病的概率为1/4,生男生女的概率又为1/2,所以第二胎还是生白化病儿子的几率是1/4×1/2=1/8。故选B
