王青梅:对方辩友一直在罗列科技给人们带来的各种负面效应,而且一直还在诉说基因技术的危险,完全忽略了基因技术对人类做出的巨大贡献,如果说基因技术一无是处,那为什么新加坡国立教育学院还要花十年的时间,用转基因技术研制出了世界上第一朵能发光的“胡奇花”?请你做出解释。
微生物(microorganism简称microbe)是包括细菌、病毒、真菌以及一些小型的原生动物等在内的一大类生物群体,它个体微小,却与人类生活密切相关。
灯笼树的果实于十月生长，呈椭圆形和棕色。有趣的是，果实茎完全悬垂，顶点弯曲，果实呈笔直状态。树枝上似乎到处都是小灯笼。灯笼树不仅美丽，而且与枫叶不同，它们在秋天变成红色，成为很有前途的观赏性园林树木。一些植物发光主要是因为它们在植物的叶子中含有大量的磷，并且可以排放少量的磷化氢气体。
东北的支柱产业是什么，怎么样?
东北三省作为中国工业原料和重型装备的基地,以独有的优势支撑和引领着中国工业化进程。长期以来,东北都是中国工业化水平较高的地区。
1885年，杜堡伊斯(Dubois)在实验室里提出的萤火虫的荧光素和荧光素酶，指出萤火虫的发光是一种化学反应，后来，科学家们又得到了荧光素酶的基因。经过科学家们的研究，萤火虫的发光原理被完全弄清楚了。
新闻中经常会报道这样的感人故事,有些人得知自己即将迈入死亡的人。将自己的眼角膜捐献给社会上的陌生人,给他人带来了光明,也让自己的眼睛得以“重生”。
:核技术、航天技术、信息技术、激光技术和生物技术,在能 源、材料、自动化、海洋和环境等高新技术方面也有了长足的进 步。
转基因黄豆与非转基因有什么区别?
我们无法在外观和口味上区分转基因大豆和非转基因大豆。一般我们只能从产地和价格上区分。国内超市一般都有非转基因东北大豆出售，有标识。
至于发光藓（Schistostega osmundacea），仅是由于能反射光线，其本身并不能发光。（陈维培 译） 会发光的植物 非洲北部有一种夜光树，一到夜晚就成了火树 ，通体闪亮。起初，当地居民还以为它是什么妖魔的化身，十分害怕，谁也不敢靠近。人们甚至称它为恶魔树。

镉污染问题现状 随着我国经济的发展,各种厂矿的数量开始增多,尤其以南方的稀有金属资源较为丰富,但这也是水稻的的主要种植区。
真的有植物荧光花卉吗
研究者们试图利用基因工程技术，把萤火虫、水母或其他海中发光动物的荧光基因植入到植物中，使其发光。但这样易损伤植物肌体的DNA，不利于植物的正常生长发育，而且发出的荧光持续时间较短。运用基因方法培育出来的荧光植物也很少，最成功的就是在烟草上的运用，但荧光烟草的观赏价值极低。
因为它们温顺,非常耐寒,完全习惯于水族馆中水条件的变化,所以在水族馆中较为常见。现在能在黑暗中发光的转基因斑马鱼也被研究出来用于水族馆贸易。
说实话,有机农业的实施是为了得到有机农产品,而且有机农业的条件是非常苛刻的,除了关于休耕制度外,对于环境的要求也是非常高的。
这个发光器由发光层、透明层和反射层三部分组成。发光层拥有几千个发光细胞,它们都含有荧光素和荧光酶两种物质。在荧光酶的作用下,荧光素在细胞内水分的参与下,与氧化合便发出荧光。萤火虫的发光,实质上是把化学能转变成光能的过程。
关于这个问题,发光植物在生活中的应用有以下几个方面: 1. 环境美化:发光植物可以用于室内和室外的装饰,增添生活气息。

Sarah Alexander celebrated the start of her last year at Wells College the way many other seniors before her have. She ran across the picturesque campus to the shores of Cayuga Lake, where she jumped into the water.
So did many of her fellow seniors, But dozens of students decided to stay away, especially the relatively few newly arrived male students.
Wells College, which since 1868 had educated only women, began accepting men this year in hopes of bolstering its dwindling enrollment. For many students and alumnae, it was a crushing decision. After the college announced last October that it would go coeducational, about half of the students protested and two filed a lawsuit, which they later dropped.
The students -- 33 men and 383 women -- came to campus late last month. Both sexes are now tring to navigate the new social landscape. Mr. Phillips said "You can't do guy stuff. Every time you want to sit and watch sports or a game, it turns into a movie." The women were "somewhat nasty.'' "I could see the dirty looks in their eyes," he said. "But I was not going to let that stop me from coming."
Wells was a place where women did not have to fuss over their appearance or fight to be taken seriously by their professors. They could enjoy the camaraderie of their campus sisters and their playful traditions. Besides jumping into the lake, the women dance around the maypole each May and kiss the feet of the statue of Minerva, the Roman goddess of wisdom, before exams.
Ms. Alexander said, "People told us we wouldn't notice a difference, but from the moment men arrived on campus you could notice a difference. Women are waking up early to put on makeup, and that's odd," she said.
Henry Wells, a founder of Wells Fargo and a friend of Comell's benefactor, Ezra Cornell established this college, when women were not considered capable of higher learning. "Give her the opportunity," he wrote.
The news that the college would go coed created ripples far beyond campus, One alumna wrote a letter to the college's president, Lisa Marsh Ryerson, saying the founder would haunt her. "I believe Henry Wells would have haunted me if I let Wells College close," said Ms. Marsh Ryerson, a Wells alumna herself.
The great-great-great-great granddaughter of Henry Wells, Stephanie Redmond, 18, of Washington State, said that earher this year a Wells student had tracked her down and asked her to support the protest. But Ms. Redmond said the move to admit men had encouraged her to emoll at Wells this year as a freshman. She plans on a career in engineering, a male-dominated field, and said attending an all-women's college might have put her at a disadvantage.
49. The primary reason for the Wells College to accept men is that ______
A. its enrollment rate is in decline
B. the campus is lack of vigor and vitality
C. it will face the destiny of being closed down
D. all-women's college might put a woman at a disadvantage
50. A typical behavior for seniors to do is that ____
A. they jog along the picturesque campus
B. they switch sports programs to a movie
C. they celebrate their fourth year by jumping into a lake
D. they swim in Cayuga Lake accompanied by friends
51. The change after turning into a coed college is that
A. dirty looks in women's eyes have disappeared
B. women get up early to make up
C. women are waking up early to study
D. women dance with men around the maypole
52. The attitude of the author is that ______
A. she hates a tradition of all-women schools
B. she calls on women in support of the protest
C. she dislikes the change and hopes to file a lawsuit
D. she objectively describes the new and uneasy coeducation
53. Which of the following statements is Not true?
A. The enrollment Of male students caused controversy.
B. The grandchildren of the college founder benefited most.
C. The current president of the college was also its graduate.
D. The founder hoped to give women opportunities of higher education.
But what is teacher quality? How can one measure it reliably?
An analysis is issued on a sample of data from a Texas school district. Experts argue convincingly that teacher effectiveness should be measured by students' gains on standardized tests: Mr. Smith is presumably a better teacher than Ms. Brown if his students consistently improve their test scores more than hers do.
Though this approach is appealing, them are tricky issues. For example, what if Ms. Brown teaches in a school where students score so high them is little room for improvement?
The authors try to correct for this problem, as well as other sorts of measurement issues, to generate a measurement of teacher effectiveness. The paper is primarily concerned with how this measure is related to other observable teacher characteristies. The first finding is that there is a large variation in teacher effectiveness: some teachers consistently have a larger impact on their students' achievement than others.
Second, easily observable characteristics like having a master's degree or a passing score on the teacher certification exam are not correlated with teacher effectiveness.
Then what does matter? The most important single influence is experience: first-year teachers are much less effective than others. The second year is significantly better, and by the fourth year, most teachers hit their stride.
It is not entirely clear whether this experience effect is learning by doing (the more you teach, the more effective you become) or survival of the fittest (those who are not good at teaching tend to drop out early).
From my reading of the paper, both effects appear important and there is no simple answer. The data do suggest, however, that teacher effectiveness is pretty clear by the end of the second year, so the information to make an informed decision is available at that time.
The authors also investigate the contentious issue of racial matching of students and teachers. Here they find strong evidence that minority teachers tend to be more effective with minority students. Again, it is unclear whether this is because of a role model effect (students respond better to a teacher of their own race) or an empathy effect (teachers empathize better with students of their own race) or something else entirely.
The authors also look at teacher mobility. There is some evidence that teachers who quit teaching or switch schools tend to be below average in effectiveness. This is consistent with the survival-of-the-fittest model.
54. The schoolmaster could decide wisely whether to further employ the teacher by the end of the
A．the first year B. the second year C．the third year D. the fourth year
55. The phrase "hit their stride" most probably means"_____"
A. reach their normal level B. become confident

A. teachers will perform better with time passing
B．ineffective teachers should leave earlier rather than later

D. a master's degree will improve teacher's effectiveness

B．Teachers sympathize with students of their own race,
C. There are entirely some other identified reasons.
D．The reasons are far from clear and definite.
58. Which of the following may serve as the best title?
A. Tenure, Turnover and the Quality of Teaching
B. Impact of Teacher Quality on Student Learning
C. Different Sorts of Measurement Issues
D. Survival-of-the-fittest Model vs. Learning-by-doing Model
