参考答案:核仁是rRNA合成及加工核糖体亚单位的场所,它包括FC、DFC和GC三个区域。

核仁组织区(NOR)是同源染色体上的含有许多rRNA基因拷贝的特殊区域,在间期时就是核仁中的FC(纤维中心)。

核仁染色体是指拥有核仁组织区的染色体(有些生物的NOR是位于次级缢痕处,如:人的13、14、15、21、22号染色体)

Mr. Jackson lived in the center of London but he had a hotel near the airport. There a lot of foreigners stayed for night. He didn’t know any other language but English and he found it difficult for him to understand the foreign visitors. Sometimes he had to use the gesture to talk with them, and tried his best to make himself understood. But he was often misunderstood (误解) and it brought him a lot of trouble. A friend of his who taught a few foreign languages in a university would teach him. He was happy and studied hard. At first he learned some, but soon he found it wasn’t very easy to remember the words and expressions. His friend advised him to write down the useful expressions in his notebook so that he could use them when necessary. He did as he was told. He found it helpful for him to do so.

He was wandering (徘徊) there and waiting for his wife who was dressing herself up upstairs. Mr. Jackson thought to himself, “ The man wants to eat something but he doesn’t know any English.

(37分)交通是人类历史进程的一个重要侧面,在历史发展的每一阶段,几乎都可以看到交通进步的轨迹,并对经济发展和社会进步产生重大影响。阅读下列材料,回答相关问题:

材料一  纺织工业、采矿工业和冶金工业的发展引起对改进过的运输工具的需要,这种运输工具可以运送大宗的煤和矿石。……1830年以后,公路和水路受到了铁路的挑战。……将蒸汽机安装在货车上,这方面的主要人物是采矿工程师乔治·斯蒂芬森,他首先利用一辆机车把数辆煤车从矿井拉到泰恩河。……短短数年内,铁路支配了长途运输,能够以比在公路或运河上所可能有的更快的速度和更低廉的成本运送旅客和货物。到1838年,英国已拥有500哩铁路;到1850年,拥有6600哩铁路;到1870年,拥有15500哩铁路。                                 ——[美]斯塔夫里阿诺斯《全球通史》

材料二  1870~1900年的铁路网单位:千公里

年份全世界欧洲美洲亚洲非洲澳洲
1870年21010593822
1880年372 1691751658
1890年61722433l34919
1900年760284402602024
                              ——吴于廑、齐世荣主编《世界史》

材料三 光绪六年岁末,刘铭传力请修筑铁路,李鸿章立足中外,比较支持刘铭传的倡议,……。但更多的人却不但责骂刘铭传与李鸿章“直欲破坏列祖列宗之成法以乱天下”,而且宣言“铁路行之外夷则可,行之中国则不可。”洋务派虽冲破阻力“毅然兴办”,但步履之艰难可以体味。

一些闭塞地区的经济因铁路活跃,一些古老的城镇因铁路而面目一新……铁路在畅通经济、带动繁荣的同时还意味着信息的流通、知识的传播,意味着建立“铁路交通日常急需的各种生产过程”,所有这一切,无疑都有助于打破中国传统社会“自给自足的惰性”,推动现代化进程。

材料四  新中国成立前,福建通往省外的铁路曾进行过6次勘测,但始终未有过修建计划。新中国成立后,闽籍爱国侨领陈嘉庚在全国政协第一届全体会议上,向大会提出修建福建铁路的提案并获得通过,但因朝鲜战争爆发未能实施,不过,毛 * * 对此做出批示:“此事目前虽一时不能兼顾,但福建筑路的正确意见,当为彻底支持。”1951年国庆期间,时任福建省委第一书记的张鼎丞又向中央和华东局建议,尽快考虑修建鹰潭至南平的铁路,以解决福建出省通道的问题。福建省委认为,修建福建铁路应从长远考虑,固然应以国防为主,但必须结合福建的经济状况。1954年9月,铁道部确定由铁道兵担任鹰厦铁路的施工。……1957年全线开始正式通车,全长约700公里。鹰厦铁路的建成通车,是当时福建开天辟地的一件大事。
