基因疫苗(又称DNA疫苗)是目前发展最快、备受人们重视的一个研究领域。1990年Wolff等在进行基因治疗实验时,以裸DNA注射作对照,结果意外发现裸DNA可被骨骼肌细胞吸收并表达出外源性蛋白。1992年Tang等首次证明经基因免疫产生的外源性蛋白质可刺激小鼠免疫系统产生特异性抗体,从而宣告基因疫苗的诞生。基因疫苗的作用原理见下图。其中①表示抗原,②③表示某种物质,④⑤代表某种细胞。

据图回答下列问题。

(1)细胞④⑤分别代表________;细胞④在①的刺激下分泌的物质②是________;③能特异性的识别①,③是________;呈递抗原的细胞是________。

(2)抗原基因在体内持续______________,不断刺激机体的免疫系统产生________________,免疫效果可靠。

(3)抗体产生后可以和病原体结合,从而抑制病原体的____________________。效应T细胞清除被病原体感染的细胞是通过________(填细胞器)完成的。

(4)请简述如何实现一种基因疫苗可预防多种疾病。____________________________。

I heard many parents complaining that their teenage children are rebelling. I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own two feet. But take a good look at the present rebellion. It seems that teenagers are taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own, most of them are clutching (紧握) at one another’s hands for reassurance.

They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up huddled (聚在一起) round listening to the same record. Their reason for thinking or acting in thus-and-such a way is that the crowd is doing it. They have come out of their cocoon (蚕茧) into a larger cocoon.

It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Industry has firmly carved out a teenage market. These days every teenager can learn from the advertisements what a teenager should have and be. And many of today’s parents have come to award high marks for the popularity of their children. All this adds up to a great barrier for the teenager who wants to find his or her own path.

But the barrier is worth climbing over. The path is worth following. You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records. You may have some thoughts that you don’t care to share at once with your classmates. Well, go to it. Find yourself. Be yourself. Popularity will come — with the people who respect you for who you are. That is the only kind of popularity that really counts.
