阅读下面两个材料并回答问题：
【材料一】2011年10月3日，诺贝尔奖委员会宣布，美国科学家布鲁斯·巴特勒、卢森堡科学家朱尔斯·霍夫曼和加拿大科学家拉尔夫·斯坦曼获得2011年诺贝尔医学生理学奖。在长期进化过程中人体具备两种免疫机能：一是“固有免疫”，二是“获得性免疫”。布鲁斯·巴特勒、朱尔斯·霍夫曼的获奖领域在前者；而拉尔夫·斯坦曼的工作主要在后者。
布鲁斯·巴特勒、朱尔斯·霍夫曼发现了由“Toll”基因编码的关键受体蛋白，该受体蛋白能识别病原微生物，并激活“固有免疫”，打开免疫反应的第一步；拉尔夫·斯坦曼发现的树突状细胞在免疫应答中作用，树突状细胞在体内游弋，发现并摄取病原体的特异性抗原，并报告给T淋巴细胞，T细胞将调动其他免疫细胞发生级联反应，最终消灭病原体。
（1）材料中所描述的“固有免疫”就是_____________________免疫，这种免疫对所有的病原体都有防御作用。（1分）
（2）下列有关“Toll”基因的叙述正确的是：_____________（单选）（1分）
A．Toll基因只存在于免疫细胞中
B．Toll基因编码受体蛋白，体现基因对性状的直接控制
C．Toll基因编码的受体蛋白能识别病原微生物，体现了免疫细胞的特异性识别
D．效应T细胞能与靶细胞密切接触就是该受体功能体现
（3）下列有关树突状细胞的叙述正确的是：_____________________（不定项）
A．树突状细胞在免疫中发挥作用，说明神经系统与免疫系统功能密切相关
B．在细胞免疫和体液免疫中树突状细胞所起的作用没有明显差别
C．树突状细胞能够处理和呈递病原体的抗原特异性
D．树突状细胞可触发T细胞发生免疫反应
E．树突状细胞可能是一种吞噬细胞
【材料二】（根据南方周末《乔布斯的错误与诺奖得主的试验》整理）就在瑞典卡罗琳医学院宣布本年度诺贝尔医学奖的前3天，斯坦曼因胰腺癌不幸离世，他没能亲耳听到自己获奖的喜讯，令人惋惜。就在他离世死后的第6天“改变世界”的IT精英乔布斯也因胰腺癌英年早逝。
两人所患的胰腺癌都是死亡率极高的恶性肿瘤。乔布斯患的是“胰腺内分泌型肿瘤”，该病症病情发展缓慢，能存活数年的患者不在少数。但这位著名的素食主义者曾一度拒绝手术治疗，导致肿瘤细胞转移，病情迅速恶化。
而斯坦曼所患的病症为“胰腺外分泌型肿瘤”，该病患者的存活期往往只有数月。斯坦曼在2007年确诊胰腺癌后，就积极尝试基于树突状细胞的治疗性疫苗(DC疫苗)。借助这种“细胞免疫疗法”，他的生命从预期的数月延长至4年。
（4）乔布斯癌变的细胞可能是_____________细胞，该细胞的分泌物与_________________。系统消灭癌细胞的过程是_____________（填一种特异性免疫）发挥作用。
（5）斯坦曼所注射的DC疫苗是由其体内的树突状细胞和肿瘤细胞中提取的一种短肽（即治疗性疫苗），该短肽在免疫中作为_____________引起人体发生免疫反应。除树突状细胞外，斯坦曼体能够特异性识别这种短肽的细胞还有（至少写出3种）______________________________________。
（6）有人认为DC疫苗对防治癌症有一定的疗效，原因是：通过免疫反应斯坦曼体内的免疫系统产生抗体，抗体与该短肽特异性结合，使短肽失效。你认为这个解释对吗，____________，请说出你的理由：_________________________。（共2分）
（7）斯坦曼生前尝试注射过三种DC疫苗，却还是未能逃出死神的魔掌，请从免疫学的角度分析导致他死亡的可能原因是：________________________________________。

　　本篇大意是：木匠约翰给主人公的妻子做了一个小饭桌，结账时的账单上把成本费17.00、油漆料钱1.50、工价8.00和日期10一起相加，多计价10元，结果被主人发现了，但他并没有直接批评多要钱的木匠，只是诙谐地说：“月底30日做比月初10日做，还要贵些，是不是？”而且只付了木匠应得到的26.50元钱．很明显，本篇比上篇更难些，因上篇中主人公怀特和厂家双方处理的问题是直接的，直言不讳，而本篇中的主人公却是明人做暗事，肚内藏机关，木匠虽然诡谲，主人却更机灵，一眼看穿了木匠的把戏，但他处理问题颇有技巧，既解决问题，不多花钱，又不搞得很僵，双方不快，体现了现代生意场中的交往策略和洽谈风格．我国正在建设社会主义市场经济，这是法制化、规范化的市场经济，反对不正当的竞争．此文有一定的现实意义，文中的内容联系着当代的社会生活，通过英语试卷，同样可以检验学生：的审视能力．

　　Our village carpenter(木匠), John Hill, came one day and made a dining table for my wife. He made it just the right size to fill the space between the two windows. When I got home that evening, John was drinking a cup of tea and writing out his bill(账单) for the job.

　　My wife said to me, quietly, “That's his ninth cup of tea today.” But she said, in a loud voice, “It's a beautiful table, dear, isn't it?”

　　“I'll decide about that when I see the bill,” I said.

　　John laughed and gave me his bill for the work. I read:

　　When I was looking at the bill, John said, “It's been a fine day, hasn't it? Quite sunny.”

　　“Yes,” I said. “I'm glad it's only the 10th of November.”

　　“Me, too,” said John. “You wait-it'll be a lot colder by the end of the month.”

　　“Yes. Colder-and more expensive! Dining tables will be ￡20 more expensive on November 30th, won't they, John?”

　　John looked hard at me for half a minute. Was there a little smile in his two blue eyes? I gave his bill back to him.

　　“If it isn't too much trouble, John,” I said, “please add it up again. You can forget the date.”

　　I paid him ￡26.50 and he was happy to get it.

1．Why did John talk about the weather when the writer was looking at the bill?

B．Because it was really a fine day.

C．Because he wanted the writer to check the bill carefully.

D．Because he wanted to tell the writer what the weather was like.

2．Why did the writer say that dining tables would be ￡ 20 more expensive on November 30th?

[　　]

A．Because it was difficult to make dining tables in cold weather.

B．Because paint would be more expensive.

C．Because the cost of wood would be more expensive.

D．Because he thought John would almost certainly add the date to the cost of the dining table.

3．The writer thought John would ask for ________ if he made a dining table on the last day of November.
