单项选择题

With the spread of inter-active electronic media a man alone in his own home will never have been so well placed to fill the inexplicable mental space between cradle and crematorium. So I suspect that books will be pushed more and more into those moments of travel or difficult defecation (1) people still don’t quite know what to do with.

When people do read, I think they’ll want to feel they are reading literature, or (2) something serious. (3) you’re going to find fewer books presenting themselves as no-nonsense and (4) assuming literary pretensions and being packaged as works of art. We can expect an extraordinary variety of genre, but with an underlying (5) of sentiment and vision.

Translators can only (6) from this desire for the presumably sophisticated. We can look forward to lots of difficult names and fantastic stories of foreign parts enthusiastically (7) by the overall worship of the "global village’. Much of this will be awful and some wonderful, (8) don’t expect the press or the organizers of prizes to offer you much help in making the appropriate distinctions. They will be chiefly (9) in creating celebrity, the greatest enemy of discrimination, but a good prop for the (10) consumer.

Every ethnic grouping over the world will have to be seen to have a great writer—a phenomenon that will (11) a new kind of provincialism, more chronological than geographic, (12) only the strictly contemporary is talked about and (13) Universities, including Cambridge, will include (14) their literature syllabus novels, written only last year. (15) occasional exhumation for the Nobel, the achievements of ten or only five years ago will be largely forgotten.

In short, you can’t go too far wrong when predicting more of the same. But there is a (16) side to this—the inevitable reaction against it. The practical things I would like to see happen--publishers seeking less to (17) celebrity through extravagant advertising, (18) and magazines (19) space to reflective pieces—are rather more improbable than the Second Coming(耶稣复临). But dullness never quite darkens the whole planet. In their own idiosyncratic fashion a few writers will (20) be looking for new departures.

Read the following text. Choose the best word(s) for each numbered blank and mark A, B, C or D on ANSWER SHEET 1.16()

A.negative

B.positive

C.paradoxical

D.controversial

填空题

2008年6月1日后,我国将限制使用塑料袋。请根据题意,回答下列问题:

(1) 我们包装食品常用聚乙烯塑料薄膜[化学式为(C2H4)n],而不用聚氯乙烯塑料薄膜[化学式为(C2H3Cl)n]。

①下列有关聚乙烯塑料和聚氯乙烯塑料的说法正确的是                         

A.用就地焚烧的方法处理废弃的聚乙烯塑料和聚氯乙烯塑料

B.聚乙烯塑料和聚氯乙烯塑都属于有机高分子合成材料

C.在聚氯乙烯塑料中C、H、Cl的元素质量比为2:3:1

D.聚乙烯塑料没有毒而聚氯乙烯塑料有毒

②废弃的聚氯乙烯塑料薄膜在空气中充分燃烧后产生水、CO2和HCl,运用下列装置检验生成的三种物质,正确的顺序是                             

(2) Mg(OH)2和Al(OH)3受热分解生成的气态水可覆盖火焰、驱逐O2、稀释可燃气体,分解产物MgO和Al2O3能较快地与塑料燃烧过程中产生的酸性及腐蚀性气体反应,所以它们可以作为未来发展方向的无机阻燃剂。

①写出Al(OH)3受热分解的化学方程式                                  

②Mg(OH)2和Al(OH)3受热分解的产物能灭火的原理是                             

③若燃烧的是聚氯乙烯塑料,MgO和Al2O3与其中的酸性气体反应的方程式(只要写一个)
