Passage 2

Directions: For question 1—5, choose the most suitable paragraphs from the list A—G and fill them into the numbered boxes to form a coherent text. Paragraphs D and E have been correctly placed.

[A] For publishers, though, it is a dangerous time. Book publishing resembles the newspaper business in the late 1990s, or music in the early 2000s. Although revenues are fairly stable, and the traditional route is still the only way to launch a blockbuster, the climate is changing. Some of the publishers functions—packaging books and promoting them to shops—are becoming obsolete. Algorithms and online recommendations threaten to replace them as arbiters of quality. The tide of selfpublished books threatens to swamp their products. As bookshops close, they lose a crucial showcase. And they face, as the record companies did, a nearmonopoly controlling digital distribution: Amazon’s grip over the ebook market is much like Apple’s control of music downloads.

[B] They also need to become more efficient. Digital books can be distributed globally, but publishers persist in dividing the world into territories with separate editorial staffs. In the digital age it is daft to take months or even years to get a book to market. And if they are to distinguish their wares from selfpublished dross, they must get better at choosing books, honing ideas and polishing copy. If publishers are to hold readers’ attention they must tell a better story—and edit out all the spelling mistakes as well.

[C] For readers, this is splendid. Just as Amazon collapsed distance by bringing a huge range of books to outoftheway places, it is now collapsing time, by enabling readers to download books instantly. Moreover, anybody can now publish a book, through Amazon and a number of other services.

[D] During the next few weeks publishers will release a crush of books, pile them onto delivery lorries and fight to get them on the display tables at the front of bookshops in the runup to Christmas. It is an impressive display of competitive commercial activity. It is also increasingly pointless.

[E] Yet there are still two important jobs for publishers. They act as the venture capitalists of the words business, advancing money to authors of worthwhile books that might not be written otherwise. And they are editors, picking good books and improving them. So it would be good, not just for their shareholders but also for intellectual life, if they survived.

[F] More quickly than almost anyone predicted, ebooks are emerging as a serious alternative to the paper kind. Amazon, comfortably the biggest ebook retailer, has lowered the price of its Kindle ereaders to the point where people do not fear to take them to the beach. In America, the most advanced market, about one fifth of the largest publishers sales are of e books. Newly released blockbusters may sell as many digital copies as paper ones. The proportion is growing quickly, not least because many bookshops are closing.

[G] They are doing some things right. Having watched the record companies impotence after Apple wrested control of music pricing from them, the publishers have managed to retain their ability to set prices. But they are missing some tricks. The music and film industries have started to bundle electronic with physical versions of their products—by, for instance, providing those who buy a DVD of a movie with a code to download it from the internet. Publishers, similarly, should bundle e books with paper books.

D→1→2→3→E→4→5

2008-77.治疗呃逆,应首选的腧穴是
A.睛明 B.水沟 C.承泣 D.攒竹

答案:D
解析:
D。攒竹治疗呃逆有特效。睛明和水沟治疗急性腰扭伤效佳。

为使票据法律关系得以确定,需要付款人进行“承兑”才能有效的工具是()。

A.本票
B.支票
C.债券
D.汇票
答案:D
解析:
承兑是指汇票付款人承诺在汇票到期日支付汇票金额的票据行为。承兑是汇票特有的一种制度。因为汇票的出票人在出票时,是委托他人(付款人)代替其支付票据金额,而该付款人在出票时并未在票据上签章,并非票据债务人,无当然的支付义务。为使票据法律关系得以确定,就需要确认付款人能否进行付款,于是就设计了汇票的承兑制度。

简述刑法上的意外事件的特征。

答案:
解析:
(1)行为在客观上造成了损害后果。 (2)行为人对自己行为所造成的结果既无故意也无过失。 (3)这种损害结果的发生是由于不能预见的原因引起的。所谓不能预见的原因,是指行为人没有预见,而且根据当时客观情况和行为人的主观认识能力,也不可能预见的原因。

DNA分子中G + C含量越高
A.解链越难 B.遗传信息越丰富
C. 50%变性时所需的温度越髙 D.复性时的最佳温度越高

答案:A,C,D
解析:
Tm指核酸分子内双链解开50%时的温度,也称解链温度。Tm大小与核酸分子中所含碱基的G + C比例有关,G+ C比例越高,Tm值越大,解链温度越高。由于G-C碱基对有3个氢键,比只有两个氢 键的A-T碱基对:更稳定,因此G+ C比例越高,解链越困难。一般认为复性的最佳条件是比Tm低25。C的 温度,因此,G + C比例越高,复性的最佳温度越高。DNA分子对遗传信息的传递和携带,是依靠碱基排列 顺序变化而定,因此与G + C含量无关。
