试题分析
应选(a).
分析本题考查向量组的线性相关性问题.数值型的情形一般用秩分析;抽象型的情形 一般利用线性相关性的结论研究分析,但若能寻求其秩时当然用秩分析求解简便.所以,对 于讨论向量组的线性相关性问题,能找秩就找秩!

directions: there are 2 passages in this section. each passage is followed by some questions or unfinished statements. for each of them there are four choices marked a ), b ), c) and d ). you should decide on the best choice and mark the corresponding letter on answer sheet 2 with a single line through the centre.
passage one
questions 11 to 15 are based on the following passage.
english is what matters. it has displaced rivals to become the language of diplomacy, of business, of science, of the interact and of world culture. many more people speak chinese--but even they, in vast numbers, are trying to learn english. so, how did it happen, and why
take the beginnings of bilingualism (两种语言) in india, for example, which has stoked (促进)the growth of the biggest english-speaking middle class in the new anglo sphere. that stems from a proposal by an english historian, thomas macaulay, in 1835, to train a new class of english speakers: a class of persons, indian in blood and colour, but english in taste, in opinion, in morals, and in intellect. at a stroke, notes mr. mc crum, english became the language of government, education and advancement, at once a symbol of imperial rule as well as of self-improvement. indias english-speaking middle class is now one of the engines of that countrys development and a big asset in the race to catch up with china.
bit by bit, english displaced french from diplomacy and german from science. the reason for this was americas rise and the lasting bonds created by the british empire. but the elastic (灵活的),forgiving nature of the language itself was another. english allows plenty of sub-variants, from singlish. in singapore to estglish in estonia: the main words are familiar, but plenty of new ones dot the lexicon, along with distinctive grammar and syntax.
english as spoken by non-natives, however, is different. listen to a south korean businessman negotiating with a pole in english and you will hear the difference: the language is curt, emphatic, stripped-down. yet within spoken globish, as mr. mccrum neatly names it, hierarchies (等级) are developing. those who can make jokes in globish score over (优于) those who cant.
the big shift is towards a universally useful written globish. spellchecking and translation software mean that anyone can communicate in comprehensible (可理解的) written english. the english of e-mail, twitter (一个社交网络和微服务网站) and text messaging is becoming far more mutually comprehensible than spoken english, which is fractured (支离破碎的) by differences in pronunciation, politeness and emphasis. mr. mccrum aptly names the new lingo (语言) an avenue for all thoughts.
