[限时检测] [限时30分钟] Ⅰ.阅读理解 A (2022·邹城高二期中)According to a recent study，a new genetically modified(转基因的) rice can prevent infections of HIV，the virus responsible for the disease AIDS. The study reports the newly­developed rice produces proteins(蛋白质)that attach directly to the HIV virus.This process keeps the virus from mixing with human cells.The scientists say it can remove the effect of the virus and block its spreading. The Joint United Nations Program on HIV/AIDS reports that worldwide，nearly 37 million people were living with HIV in 2017.The organization says the largest number of those are in developing countries.Nearly two­thirds of HIV cases are in Africa.Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease. The new study predicts the rice­based method will lead to long­term use of the anti­HIV treatment across the developing world.Researchers said the “groundbreaking” discovery is “realistically the only way” that anti­HIV combination treatments can be produced at a cost low enough for the developing world. They say the easiest and most cost­effective way to use the rice will be to make it into a cream to be put on the skin.The HIV­fighting proteins can then enter the body through the skin.People all over the world could grow the rice and make the cream themselves.This would prevent the cost and travel required for many patients to receive treatments and medicine. The process of changing the genetic structure of food crops has been debated for some time.Critics of genetically engineered crops believe they can harm people.The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to people.
