问题     The US Food and Drug Administration (FDA) is taking steps to protect the country’s blood supply. People give blood to the centers, where it is kept until it is needed for medical purposes. The FDA has provided new rules for the blood centers. The government agency says new rules are designed to improve the blood supply system. The new rules call for blood centers to develop more ways to make sure their work is done correctly. These rules are another way to help keep the blood supply pure. A leading concern is that someone with AIDS virus might give blood to a blood center. For this reason, there are tests to find out if blood contains viruses that cause AIDS and other disease. Each year blood transfusion has saved millions of lives, however, if there is no secure blood, it’s increasingly risky for the recipient of blood to be infected with HIV.
选项
答案 美国食品与药品管理局正在采取措施保护美国的血液供应。人们向血液中心提供血液，供血贮存在血液中心，直到用于医疗目的。美国食品与药品管理局为血液中心制定了新的规则。政府机构称，新规则旨在改善血液供应系统。根据新规则，血液中心将采取更多办法，以确保其工作的顺利进行。这是有助于供血纯净的又一途径。最令人关注的是，艾滋病病毒携带者也可能向血液中心供血，因此，应该检验血液是否携带可能导致艾滋病或其他疾病的病毒。每年通过输血挽救了数百万人的生命，但如果血液安全没有保证，受血者感染艾滋病病毒的风险就会上升。
