问题:

某工程项目合同工期为18个月。施工合同签订以后,施工单位编制了一份初始网络计划,如下图所示。并经监理工程师批准执行。

由于该工程施工工艺的要求,计划中工作C、工作H和工作J需共用一台起重施工机械,为此需要对初始网络计划进行调整。

如果各项工作均按最早开始时间安排,起重机械在现场闲置多长时间为减少机械闲置,工作C应如何安排?

阅读韩愈的《马说》文,并回答问题。

  世有伯乐,然后有千里马。千里马常有,而伯乐不常有。故虽有名马,祗辱于奴隶人之手,骈死于槽枥之间,不以千里称也。

  马之千里者,一食或尽粟一石。食马者不知其能千里而食也。是马也,虽有千里之能,食不饱,力不足,才美不外现,且欲与常马等不可得,安求其能千里也?

  策之不以其道,食之不能尽其材,鸣之不能通其意,执策而临之,曰:“天下无马!”呜呼!其真无马邪?其真不知马也。

1、用“/”标出下面句子朗读的语意停顿。(每句标一处)

安求其能千里也?

食之不能尽其材。

2、联系上下文,解释下面加粗字的意思。

马也,虽有千里之能(     )

马者不知其能千里而食也(     )

之不以其道(     )

一食尽粟一石(     )

3、下面各组加粗字词的意思或用法完全相同的一组是(     )

A.虽有千里之/安求其千里也

B.真无马邪/策之不以

C.鸣而不能通其意/环而攻而不胜

D.祗辱于奴隶人手/学而时习

4、本文托物寓意,文中的“千里马”喻指人才,“伯乐”喻指_______________,而将愚妄浅薄的封建统治者比作“__________________”。

5、有这样一个故事:一匹骨瘦如柴的老马拉着盐车上山坡,气直喘,汗直流,竭尽全力还是拉不上去。赶车的人吆喝着,用鞭子狠狠地抽打它……这时,一个路过的相马的人看见了,心疼得流下泪,急忙脱下衣裳披在瘫倒在地的老马身上。老马睁开眼,看到相马人,眼睛一亮,长嘶一声而逝。请你展开想像,写出老马临死前想对相马人表达的意思。(100字内)

阅读以下文字。


美国科学家们近日首次拍摄到了HIV(人类免疫缺陷病毒)在人体内的扩散,他们发现HIV病毒以一种先前未知的方式从感染细胞转移到健康细胞。这是科学家们在了解HIV扩散过程方面所取得的一项重大突破。研究人员创建了一个感染HIV病毒的克隆分子,并将一个蛋白插入其遗传编码,此克隆病毒暴露在蓝光下即可发出绿光。这使科学家们可在数字视频设备上看到这些细胞,并捕获感染HIV的T细胞与未感染细胞进行互动的方式。他们指出,当被感染细胞接触到健康细胞时,它们之间就会建立起一座称为病毒突触的“桥梁”。这样,研究人员就能观察到绿色荧光病毒微粒向突触移动并进入健康细胞。
此项研究揭示,病毒蛋白正是这样通过突触聚集而进入未感染细胞的。本研究的研究人员称,此项发现或许可以解释艾滋病疫苗的开发为什么至今都不太成功,研究成果将有助于创建出对抗HIV和艾滋病的新治疗方案。该研究的研究人员认为:“我们对此种转移模式了解得越多,我们就越有机会搞清楚如何来阻断HIV和艾滋病的扩散。”
数十年来,人们一直相信,HIV主要通过自由流动粒子在身体内进行扩散,这些粒子可将自身附着在一个细胞上,接管其复制机制,然后制作出自己的诸多副本。2004年,科学家就发现,HIV在细胞间的转移可通过病毒突触发生,但是他们无法了解为何这一过程在病毒扩散中如此有效。基于此,以前开发HIV疫苗的努力都集中在启动免疫系统来识别和攻击自由流动病毒蛋白。
新的视频显示,HIV可通过在细胞间直接转移来规避识别。该研究的研究人员说,他们正在开发可帮助免疫系统识别含有病毒突触格式蛋白的疫苗及以突触形成所需因子为靶标的抗病毒药物。他们认为,经由病毒突触的“T细胞—T细胞”直接转移是HIV病毒感染的一个高效途径,这也许是最主要的传播模式。

根据第1段内容可知,绿色荧光有助于()。

A.使蓝光变成绿光

B.病毒微粒向突触移动并进入健康细胞

C.在数字视频设备上看到HIV细胞

D.帮助蛋白插入感染HIV的分子

Perhaps only a small boy trained to be a wizard at the Hogwarts School of Magic could cast a spell so powerful as to create the biggest book launch ever. Wherever in the World the clock strikes midnight on June 20th, his followers will flock to get their paws on one of more than 10m copies of "Harry Potter and the Order of the Phoenix". Bookshops will open in the middle of the night and delivery firms are drafting in extra staff and bigger trucks. Related toys, games, DVDs and other merchandise will be everywhere. There will be no escaping Potter mania.

Yet Mr. Potter’s world is a curious one, in which things are often not what they appear. While an excitable media (hereby including The Economist, happy to support such a fine example of globalization) is helping to hype the launch of J. K. Rowling’s fifth novel, about the most adventurous thing that the publishers have organized is a reading by Ms. Rowling in London’s Royal Albert Hall, to be broadcast as a live web cast.

Hollywood, which owns everything else to do with Harry Potter, says it is doing even less. Incredible as it may seem, the guardians of the brand say that, to protect the Potter franchise, they are trying to maintain a low profile. Well, relatively low.

Ms. Rowling signed a contract in 1998 with Warner Brothers, part of AOL Time Warner, giving the studio exclusive film, licensing and merchandising rights in return for what now appears to have been a steal: some $ 500,000. Warner licenses other firms to produce goods using Harry Potter characters or images, from which Ms. Rowling gets a big enough cut that she is now wealthier than the queen--if you believe Britain’s Sunday Times rich list. The process is self-generating: each book sets the stage for a film, which boosts book sales, which lifts sales of Potter products.

Globally, the first four Harry Potter books have sold some 200m copies in 55 languages; the two movies have grossed over $1.8 billion at the box office.

This is a stunning success by any measure, especially as Ms Rowling has long demanded that Harry Potter should not be over-commercialized. In line with her wishes, Warner says it is being extraordinarily careful, at least by Hollywood standards, about what it licenses and to whom. It imposed tough conditions on Coca-Cola,. insisting that no Harry Potter images should appear on cans, and is now in the process of making its licensing programmed even more restrictive. Coke may soon be considered too mass market to carry the brand at all.

The deal with Warner ties much of the merchandising to the films alone. There are no officially sanctioned products relating to "Order of the Phoenix"; nor yet for "Harry Potter and the Prisoner of Azkaban", the film of the third book, which is due out in June 2004. Warner agrees that Ms. Rowling’s creation is a different sort of commercial property, one with long-term potential that could be damaged by a typical Hollywood marketing blitz, says Diane Nelson, the studio’s global brand manager for Harry Potter. It is vital, she adds, that with more to come, readers of the books are not alienated. "The evidence from our market research is that enthusiasm for the property by fans is not warning.\

Ms. Rowling’s reading in London’s Royal Albert Hall is mentioned to show()

A. publishers are really adventurous in managing the Potter’s business

B. businesses involved with Potter are moving along in an unusual way

C. the media are promoting Potter mania more actively than Hollywood

D. businesses are actually more credible than media in Potter’s world
