To try to minimize the effects, public officials are still urging anyone who hasn?t yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫苗 ) with its excellent 36 percent effectivenesswould not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here39。s what goes on in your body when you e down with the flu. The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune(免疫的 )response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover. The virus usually enters through your mouth, typically by way of your hands But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it39。s nothing major, and nothing like the symptoms that typically acpany a bad or even mild case of the flu. The real fun starts when your immune system begins to fight. Your immune system es in two parts: the innate system and the adaptive. The innate immune system is essentially an allpurpose tool. As soon as your body senses the presence of any injury or invader (入侵者 ), the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates an serious inflammation(炎癥 ) throughout the body. But the worst is still to e. Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what39。s special about it, and create something unique on their surface that finds and destroys similar invaders. 28. What can we infer from Paragraph 1? A. All the vaccine is not effective. B. No one can avoid catching this year39。s flu. C. This year39。s flu is the most serious one in recent years. D. Public health officials have to use a gun when necessary. 【答案】 A 【解析】 本文主要講了流感病毒是如何侵襲人體，讓人類生病，以及人類的免疫系統(tǒng)是如何和流感病毒做斗爭，讓人們恢復(fù)健康的。 推理判斷題。由 However, even if every single person got a shot in the arm, the vaccine(疫苗 )——with its excellent 36 percent effectiveness——would not prevent everyone from getting infected with the annoying ，選 A。 29.
