This year’s flu season is pretty scary. 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 effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come 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, it's nothing major, and 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 system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader , 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 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 a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.

I always felt sorry for the people in wheelchairs. Some people, old and weak, cannot get around by themselves. Others seem perfectly healthy, dressed in business suits. But whenever I saw someone in a wheelchair, I only saw a disability, not a person.
Then I fainted(昏倒)at Euro Disney due to low blood pressure. This was the first time I had ever fainted, and my parents insisted that I rest for a while after first aid. They said to me, “Never mind!” I agreed to take it easy, but as I stepped toward the door, I saw my dad pushing a wheelchair in my direction! Feeling the color burn my cheeks, I asked him to wheel that thing right back to where he found it.
I could not believe this was happening to me. Wheelchairs were fine for other people but not for me, as my father wheeled me out into the main street, people immediately began to treat me differently.
Little kids ran in front of me, forcing my father to stop the wheelchair suddenly. I was thrown back and forth. “Stupid kids! They have perfectly good legs. Why can’t they watch where they are going?” I thought. People stared down at me, pity in their eyes. Then they would look away, maybe because they thought the sooner they forgot me the better.“I’m just like you!” I wanted to scream.” The only difference is you’ve got legs, and I have wheels.”
People in wheelchairs are not stupid. They see every look and hear each word. Looking out at the faces, I finally understood: I was once just like them. I treated people in wheelchairs exactly the way they did not want to be treated. I realized it is some of us with two healthy legs who are truly disabled.

3.What is the best title for this passage?

B.People in wheelchairs should be treated equally.
C.People whth two lges are truly healthy.
D.The difference between healthy people and the disabled.
