克隆羊的成功轰动世界，它不仅奠定了克隆性治疗疾病的基础，又解决了器官移植中供体不足的问题，同时也给人类带来了一些过去尚未遇到的问题。下图为人类对克隆羊技术的拓展和应用，请据图回答：

(1)图中所涉及的现代生物技术有__________和__________等(写出两种即可)。

(2)图中从“内细胞团到胚胎干细胞”的培养过程中，一般用_________处理内细胞团，使之分散成单个细胞。使用培养基进行胚胎干细胞培养时，通常要加入_________等天然成分，为维持培养基的pH值，需通入____________。

(3)图中两个克隆动物长大后，各方面特征与原型动物相同，这说明动物的_________具有全能性，早期胚胎发育在___________阶段开始出现分化。

(4)下列有关胚胎移植的叙述正确的是_____________。

A．冲卵指的是从子宫中冲出卵子

B．只有供、受体生理环境高度一致，移入受体的胚胎才能被接受

C．供体和受体要进行免疫检查，防止发生免疫排斥反应

D．不同动物胚胎移植的时间不同，人的胚胎移植最好在原肠胚时期进行

网络计划图由 (51) 组成，如果某工序的工期为0，则表示 (52) 。在非确定型网络计划图中，工期不是确定数，一般需估计三个数值：乐观估计时间a，最可能估计时间m，悲观估计时间不。如假定m与a的加权平均值为(a+2m)/3，m与b的加权平均值为(2m+ b)/3，当这两个时间以相同概率出现时，则可计算出工期的加权平均值 (53) ，以此作为工期，从而把非确定型问题化成确定型问题。

在下图表示的网络计划图中，关键线路是 (54) ，全部计划完成时间是 (55) 。

（52）处填（）。

A．为决策而增加的工序

B．为计算方便而增加的工序

C．工序间的时间顺序关系

D．该工序是关键工序

什么叫导热？

The time for sharpening pencils, arranging your desk, and doing almost anything else instead of writing has ended. The first draft will appear on the page only if you stop avoiding the inevitable and sit, stand up, or lie down to write. (41)______
Be flexible. Your outline should smoothly conduct you from one point to the next, but do not permit it to railroad you. If a relevant and important idea occurs to you now, work it into the draft. (42)______ Grammar, punctuation, and spelling can wait until you revise. Concentrate on what you are saying. Good writing most often occurs when you are in hot pursuit of an idea rather than in a nervous search for errors.
(43)______ Your pages will be easier to keep track of that way, and, if you have to clip a paragraph to place it elsewhere, you will not lose any writing on the other side.
If you are working on a word processor, you can take advantage of its capacity to make additions and deletions as well as move entire paragraphs by making just a few simple keyboard commands. Some software programs can also check spelling and certain grammatical elements in your’ writing. (44)______ These printouts are also easier to read than the screen when you work on revisions.
Once you have a first draft on paper, you can delete material that is unrelated to your thesis and add material necessary to illustrate your points and make your paper convincing. The student who wrote "The A & P as a State of Mind" wisely dropped a paragraph that questioned whether Sammy displays chauvinistic attitudes toward women. (45)______
Remember that your initial draft is only that. You should go through the paper many times—and then again working to substantiate and clarify your ideas. You may even end up with several entire versions of the paper. Rewrite. The sentences within each paragraph should be related to a single topic. Transitions should connect one paragraph to the next so that there are no abrupt or confusing shifts. Awkward or wordy phrasing or unclear sentences and paragraphs should be mercilessly poked and prodded into shape.
[A] To make revising easier, leave wide margins and extra space between lines so that you can easily add words, sentences, and corrections. Write on only one side of the paper.
[B] After you have clearly and adequately developed the body of your paper, pay particular attention to the introductory and concluding paragraphs. It’s probably best to write the introduction last, after you know precisely what you are introducing. Concluding paragraphs demand equal attention because they leave the reader with a final impression.
[C] It’s worth remembering, however, that though a clean copy fresh off a printer may look terrific, it will read only as well as the thinking and writing that have gone into it. Many writers prudently store their data on disks and print their pages each time they finish a draft to avoid losing any material because of power failures or other problems.
[D] It makes no difference how you write, just so you do. Now that you have developed a topic into a tentative thesis, you can assemble your notes and begin to flesh out whatever outline you have made.
[E] Although this is an interesting issue, it has nothing to do with the thesis, which explains how the setting influences Sammy’s decision to quit his job. Instead of including that paragraph, she added one that described Lengel’s crabbed response to the girls so that she could lead up to the A & P "policy" he enforces.
[F] In the final paragraph about the significance of the setting in "A & P," the student brings together the reasons Sammy quit his job by referring to his refusal to accept Lengel’s store policies.
[G] By using the first draft as a means of thinking about what you want to say, you will very likely discover more than your notes originally suggested. Plenty of good writers don’t use outlines at all but discover ordering principles as they write. Do not attempt to compose a perfectly correct draft the first time around.
