单选题Motorways are, no doubt the safest roads in Britain. Mile (21) mile, vehicle for vehicle, you axe much (22) likely to be killed or seriously injured than on an ordinary road. On (23) hand, if you do have a serious accident on a motorway, fatalities are much more likely to (24) than in a comparable accident (25) on the roads. Motorways have no (26) bends, no roundabouts or traffic lights and (27) speeds are much greater than on other roads. Though the 70 mph limit is (28) in force, it is often treated with the contempt that most drivers have for the 30 mph limit applying in built up areas in Britain. Added to this is the fact that motorway drivers seem to like traveling in groups with perhaps (29) ten meters between each vehicle. The resulting horrific pile-ups (30) one vehicle stops for some reason—mechanical failure, driver error and so on—have become all (31) familiar through pictures in newspapers or on television. How (32) of these drivers realize that it takes a car about one hundred meters to brake to a stop (33) 70 mph? Drivers also seem to think that motorway driving gives them complete protection from the changing weather. (34) wet the road, whatever the visibility in mist or fog, they (35) at ridiculous speeds oblivious of police warnings or speed restrictions (36) their journey comes to a conclusion. Perhaps one remedy (37) this motorway madness would be better driver education. At present, learner drivers are barred (38) motorways and are thus as far as this kind of driving is (39) , thrown in at the deep end. However, much more efficient policing is required, (40) it is the duty of the police not only to enforce the law but also to protect the general public from its own foolishness.

单选题{{B}}Passage 2{{/B}} The law of private international tribunals with respect to conflicts of interest of arbitrators is quite extensive, albeit by no means uniform. It relates both to what will disqualify an arbitrator and to what the arbitrator must disclose during the selection process. Most national legal systems have statutory roles as to the types of interests, relationships, and experiences that disqualify an arbitrator. Not infrequently, the disqualifying factors are identical for arbitrators and judges, although they may treat domestic and international arbitration somewhat differently, and may indeed supplement the international roles with additional features. A closer look reveals that courts and arbitration agencies tend to apply the regulations relatively lightly, recognizing that arbitrators move in the highly interconnected world of affairs, and do not stand aloof from commerce as judges do. Accordingly, acquaintanceship with the parties and their counsel does not suffice to disqualify, whereas actual business or legal connections will. Inasmuch as judges do not seek more work, although arbitrators generally do, suspicions arise that an arbitrator's favor may incline to the party or counsel who has in the past and may again in the future provide employment. The uncertainty in the field is at its most troubling when arbitrators are party-appointed. Some argue that such arbitrators should fulfill the same functions and satisfy the same qualifications as third-party arbitrators, others dispute any real claim to objectivity. The latter view has had considerable currency, particularly in the United States, where courts and drafters of state laws regard such advocates as pawns of the appointers. Imposing standards of neutrality, and disinterestedness on them would be futile. It follows from this dichotomy between party-appointed and non-party-appointed arbitrators that opinion on the question of their nationality is also split. A party needs to be expected to choose a fellow national. This question of nationality is acute when one party to the arbitration is a governmental agency and one or more of the arbitrators are likewise nationals; a foreign enterprise contract calling for such arbitration may be foolhardy. The slate is largely blank with respect to roles for the conduct of arbitrators outside the field of conflict of interests. Considering only the matter of exparte communications, American case law is astonishing lax, refusing to set aside awards where such communication obtained between an arbitrator and a party without the presence of the other party, thereby violating evidentiary rules requiring the attendance of both parties. The differences in views on this topic indicate how useful a set of guidelines might be.

单选题Tides are created mainly by the pull of the moon on the earth. The moon"s pull causes water in the oceans to be a little deeper at a point closest to the moon and also at a point farthest from the moon, on the opposite side of the earth. These two tidal "waves" follow the apparent movement of the moon around the earth strike nearly every coastline at intervals of about twelve hours and twenty-five minutes. After reaching a high point, the water level goes down gradually for a little more than six hours and then begins to rise toward a new high point. Hence, most coastlines have two tides a day, and the tides occur fifty minutes later each day. Differences in the coastline and in channels in the ocean bottom may change the time that the tidal wave reaches different points along the same coastline. The difference in water level between high and low tide varies from day to day according to the relative positions of the sun and the moon because the sun also exerts a pull on the earth, although it is only about half as strong as the pull of the moon. When the sun and the moon are pulling along the same line, the tides rise higher, and when they pull at right angles to one another, the tide is lower. The formation of the coastline and variations in the weather are additional factors which can affect the height of tides. Some sections of the coast are shaped in such a way as to cause much higher tides than are experienced in other areas. A strong wind blowing toward the shore may also cause tides to be higher.

单选题If sustainable competitive advantage depends on work-force skills．American firms have a problem．Human resource management is not traditionally seen as central to the competitive survival of the firm in the United States．Skill acquisition is considered as an individual responsibility．Labor is simply another factor of production to be hired or rented at the lowest possible cost much as one buys raw materials or equipment． The lack of importance aRached to human resource management can be seen in the corporation hierarchy．In an American firm the chief financial officer is almost always second in command．The post of head of human resource managements is usually a specialized job, often at the edge of the corporate hierarchy．The executive who holds it is never consulted on major strategic decisions and has no chance to move up to Chief Executive Officer(CEO)．By way of contrast, in Japan the head of human resource management is central—usually the second most important executive, after the CEO, in the firm's hierarchy． While American firms often talk about the vast amounts spent on training theft work-forces．in fact they invest less in the skill of their employees than do the Japanese or German firms．The money they do invest is also more highly concentrated on professional and managerial emplovees． And the limited investments that are made in training workers are also much more narrowly focused on the specific skills necessary to do the next job rather than on the basic background skills that make it possible to absorb new technologies． As a result, problems emerge when new breakthrough technologies arrive．If American workers, for example, take much longer to learn how to operate new flexible manufacturing stations than workers in Germany(as they do)，the effective cost of those stations is lower in Germany than it is in the United Stated．More time is required before equipment is up and running at capacity,and the need for extensive retraining generates costs and creates bottlenecks that limit the speed with which new equipment can be employed．The result is a slower pace of technological change．And in the end the skills of the bottom half of the population affect the wages of the top half．If the bottom half can't effectively staff the processes that have to be operated，the management and professional jobs that go with these processes will disappear．
