33、ard English is the variety of English which is usually used in print and winch is normally taught in schools and to non-native speakers leaning the language. It is also the variety which is normally (71) by educated people and used in news broadcasts and other (72) situations. The difference between

34、 standard and nonstandard, it should be noted, has (73) in principle to do with differences between formal and colloquial (74) ; standard English has colloquial as well as formal variants.(75) , the standard variety of English is based on the London (76) of English that developed after the Norman Co

35、nquest resulted in the removal of the Court from Winchester to London. This dialect became the one (77) by the educated, and it was developed and promoted (78) a model, or norm, for wider and wider segments of society. It was also the (79) that was carried overseas, but not one unaffected by such ex

36、port. Today, (80) English is arranged to the extent that the grammar and vocabulary of English are (81) the same everywhere in the world where English is used; (82) among local standards is really quite minor, (83) the Singapore, South Africa, and Irish varieties have very (84) difference from one a

37、nother so far as grammar and vocabulary are (85) . Indeed, Standard English is so powerful that it exerts a tremendous (86) on all local varieties, to the extent that many long-established dialects of England have (87) much of their vigor and there is considerable pressure on them to be (88) . This

38、latter situation is not unique (89) English: it is also true in other countries where processes of standardization are (90) . But it sometimes creates problems for speakers who try to strike some kind of compromise between local norms and national, even supranational (跨国的) ones.（分数：10.00）A.saidB.tol

42、t might affect the brain, the leader of the research team said.But Darius Leszczynski, who headed the 2-year study and will present findings next week at a conference in Quebec (魁北克), said more research was needed to determine the seriousness of the changes and their impact on the brain or the body.

43、The study at Finlands Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human cells grown in a laboratory, he said.“We know that there is some biological response. We can detect it with our very sensitiv

44、e approaches, but we do not know whether it can have any physiological effects on the human brain or human body,“ Leszczynski said.Nonetheless, the study, the initial findings of which were published last month in the scientific journal Differentiation, raises new questions about whether mobile phon

45、e radiation can weaken the brains protective shield against harmful substances.The Study focused on changes in cells that line blood vessels and on whether such changes could weaken the functioning of the blood-brain barrier, which prevents potentially harmful substances from entering the brain from

46、 the bloodstream, Leszczynski said.The study found that a protein called hsp27 linked to the functioning of the blood-brain barrier showed increased activity due to irradiation and pointed to a possibility that such activity could make the shield more permeable(能透过的), he said.“Increased protein acti

47、vity might cause cells to shrinknot the blood vessels but the cells themselvesand then tiny gaps could appear between those cells through which some molecules could pass,“ he said.Leszczynski declined to speculate on what kind of health risks that could pose, but said a French study indicated that h

48、eadache, fatigue and sleep disorders could result.“These are not life-threatening problems but can cause a lot of discomfort,“ he said, adding that a Swedish group had also suggested a possible link with Alzheimers disease.“Where the truth is, I do not know,“ he said.Leszczynski said that he, his wife and children use mobile phones, and he said that he did not think his study suggested any need for new restrictions on mobile phone use
