24、o 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 heres what goes on in your body when you come down with
25、 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 viru
26、s 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.
27、While this process might cause some harm to your nose and throat，its nothing major，and theres nothing like the symptoms that typically accompany a bad or even mild case of the flu.The real fun starts when your immune system begins to fight. Your immune system comes in two parts：the innate immune sys
28、tem 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
29、 and start to attack the virus. This increase in immune cells creates a serious inflammation (炎症) throughout the body.But the worst is still to come.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

32、效，故A项正确。9Why do many parts of your body suffer while youre recovering from the flu?ABecause recovery from illness is painful.BBecause your immune system is working against your defense system.CBecause your body is fighting hard against the flu.DBecause the influenza virus attacks your nose, throat a
33、nd other parts.C细节理解题。根据第二段最后两句可知，几乎所有的流感症状与病毒本身关系不大，它们主要是免疫系统对病毒的反应造成的，对病毒的清除是你感觉疼痛的原因，因此身体不舒服是因为身体在清除病毒，故C项正确。10The underlined word “fun” in Paragraph 4 can be replaced by _.AjoyBbattleCactionDprogramB词义猜测题。根据fight可判断battle符合要求。免疫系统开始工作意味着真正的战斗的开始。11Whats the main idea of Paragraph 4?AThe fight be
