7.WASHINGTON-Patients with HIV,the virus that causes AIDS,often develop vitamin deficiencies(缺乏).A new study has found that giving these patients a multivitamin with a mineral supplement(补充) helps improve their immunity and slows the disease's progression.Sub-Saharan Africa has always been the center of the AIDS epidemic.In Botswana,despite aggressive prevention campaigns,one out of every four adults is infected with HIV.Professor Marianna Baum based her latest research there.Baum recruited almost 900newly infected adults who had not yet received the anti-AIDS drugs that target the virus.These adults were then divided into groups that randomly received different combinations of vitamins B,C and E,the mineral selenium or a placebo(安慰剂).
Most patients with HIV become deficient in these vitamins,which help boost immunity.Baum said she initially thought the multivitamins alone or selenium alone would be effective in strengthening the immune system,but found that to be incorrect.
"We were surprised to find that only the combination was effective,"said Baum.
Research shows that when people with HIV receive anti-retroviral drugs (抗逆转录病毒药物) shortly after infection,they can remain healthy and are less likely to pass the virus to their sex partners.For many countries,however,the cost of these anti-AIDS drugs is still prohibitive.Baum said the vitamin and mineral combination therapy should help low income countries better control the virus.
"A simple multivitamin supplementation with selenium provided early in HIV disease can actually slow the HIV disease progression and it is safe.It is low cost and it should be provided very early in HIV infection,"said Baum.
Baum said the supplements are not meant to replace anti-retroviral therapy,but can help those who cannot obtain the drugs.
Dr.Anthony Fauci,a world renowned expert on AIDS,disagrees.
"I haven't read the paper,but having taken care of HIV-infected individuals for three decades,I would doubt that vitamins are going to have a major effect on suppressing the virus,"said Fauci.
Fauci said vitamin and mineral supplements may make a patient generally healthier,but the only thing that truly works to suppress HIV is anti-retroviral therapy.Baum's study was published in the Journal of the American Medical Association.

B.Vitamins will have a great impact on stopping HIV.

分析 主要讲述了携带有可发展成艾滋病的HIV病毒的病人容易引起维生素缺乏,新的研究表明多种维生素和矿物质一起补充可以帮助提高免疫力减缓HIV的感染进程.也是该类病症治疗和抑制方面的一个突破.
解答 25.B 细节题.根据文中内容WASHINGTON-Patients with HIV,the virus that causes AIDS,often develop vitamin deficiencies(缺乏).A new study has found that giving these patients a multivitamin with a mineral supplement(补充) helps improve their immunity and slows the disease's progression.,主要讲述了携带有可发展成艾滋病的HIV病毒的病人容易引起维生素缺乏,新的研究表明多种维生素和矿物质一起补充可以帮助提高免疫力减缓HIV的感染进程,这类讲述病症和治疗方法的文章一般出现在报纸上,故选B
26.D 细节题.根据文章内容,"A simple multivitamin supplementation with selenium provided early in HIV disease can actually slow the HIV disease progression and it is safe.维生素和矿物质硒的混合补充能够有效的帮助减缓艾滋病的发病,结合选项,故选D
27.C 细节题.根据文章内容,I would doubt that vitamins are going to have a major effect on suppressing the virus,"…Fauci said vitamin and mineral supplements may make a patient generally healthier,but the only thing that truly works to suppress HIV is anti-retroviral therapy由此可知,Fauci说维生素和矿物质的补充确实对病人身体好,但是他怀疑他们的结合真的能有效的作为抗逆转录病毒的治疗方法么,结合选项,故选C
28.B 词义猜测题.根据文章内容,For many countries,however,the cost of these anti-AIDS drugs is still prohibitive. 然而,对于很多国家来说,这种抗逆转录病毒药物仍旧是昂贵的,结合选项,故选B
