单选题
Money has become plastic in the age of the credit card, but in an increasing number of countries, cash really is becoming plastic. After more than 300 years in (1) , the traditional paper banknote is gradually being (2) by new polymer technology. Note Printing Australia (NPA), a wholly (3) subsidiary of the Reserve Bank of Australia, is (4) the only company in the world making plastic money, and it is (5) on an aggressive strategy to (6) more countries to its cause. The (7) of plastic notes are considerable. They cost about twice as much as paper notes but (8) four to five times as long--Australia's $ 10 paper note had a(n) (9) life of eight months but plastic lasts at least 30 months. In Papua New Guinea the 2 kina (54 cents) paper note lasted only four months but its plastic (10) lasts 24 months. This increased life (11) is particularly important in Asia where environmental conditions (12) humidity drastically reduce the life of a paper note. Plastic notes also cause 38% fewer paper jams in ATMs. But the real (13) point is that plastic notes are very hard to counterfeit. With increased (14) to computer scanners and printers, even schoolchildren can now (15) . good quality counterfeit paper notes. According to the U. S. Secret Service, which is in (16) of the security of U. S. banknotes, the $ 100 bill is the most counterfeited note in the world. The $ 100 bill (17) for 65% of the $ 500 billion (18) of U. S. banknotes in circulation, and an (19) 487,000 of these notes are fake--about 150 fakes per million notes. In Australia there are (20) about three fakes per million notes.
【答案解析】[解析] 语义衔接题。本句与上句紧密照应。上句说cash really is becoming plastic“现金正在变成塑料的(而不再是纸的了)”,本题所在句中的paper banknote相当于上句的cash; new polymer technology则对应plastic。因而可知,随着新的技术的发展,塑料钱币正在取代纸币。而[A]substitute“替换”常与for连用,比如substitute A for B,“用A代替B”,所以[A]不符合要求;[B]replaces是“替代”,符合文意;[C]“去掉”、[D]“消除”均与文意相差太远。
【正确答案】
D
【答案解析】[解析] 逻辑衔接题。由subsidiary“子公司”可知,Note Printing Australia( NPA)与the Reserve Bank of Australia是所属关系。既然是所属关系,那么当然是母公司拥有子公司,因此答案是[D]。[A]monopolized“垄断”,用来形容二者的关系显然不合适;[B]“独占”、[C]“占有”很容易排除。
【正确答案】
A
【答案解析】[解析] 语义衔接题。由文意可知,本题需要的是一个表示时间关系的状语,故[B]、[C]不能入选。[A] currently“当前”与[D]temporarily“临时”,都表示时间。但很明显,文章说塑料钱币正在an increasing number of countries中流行,不可能是暂时的。所以[D]表达的时间范畴与事实不符,答案只能是[A]。
【答案解析】[解析] 惯用衔接题。本题出现在一个which引导的非限制性定语从句中,所在句是对前面U. S. Secret Service的解释。U S. Secret Service负责U. S. banknotes的安全。In charge of...指“负责”和“掌管”某事物。从语法角度讲,其他三项均不能构成in…of…的短语,而且这几个选项的词义:[A]“花费”、[B]“购买”、[D]“追求”,都不合题意。
