回答下列各题 An industrial society, especially one as centralized and concentratedas that of Britain, is heavily dependent on certain essential services: forinstance, electricity supply, water, rail and road transport, the harbors. Thearea of dependency has widened to include removing rubbish, hospital andambulance services, and, as the economy develops, central computer andinformation services as well. If any of these services ceases to operate, thewhole economic system is in danger. It is this economic interdependency of the economic system whichmakes the power of trade unions (工会)such an important issue. Single trade unionshave the ability to cut off many countries economic blood supply. This can happen more easily in Britain than in some othercountries, in part because the labor force is highly organized. About 55 percentof British workers belong to unions, compared to under a quarter in the UnitedStates. For historical reasons, Britains unions have tended to developalong trade (行业) and occupational lines, rather than on an industry-by-industrybasis, which makes a wages policy, democracy in industry and the improvement ofprocedures for fixing wage levels difficult to achieve. There are considerable strains and tensions in the trade unionmovement, some of them arising from their outdated and inefficient structure. Someunions have lost many members because of their industrial changes. Ｏthers are involved in arguments about who should represent workersin new trades. Unions for skilled trades are separate from general unions,which means that different levels of wages for certain jobs are often a sourceof bad feelings between unions. In traditional trades which are being pushedout of existence by advancing technologies,unions can fight for their membersdisappointing jobs to the point where the jobs of other union members are threatenedor destroyed. The printing of newspapers both in the United States and inBritain has frequently been halted by the efforts of printers to hold on totheir traditional highly-paid jobs. Trade unions have problems of internal communication just asmanagers in companies do, problems which multiply in very large unions or inthose which bring workers in very different industries together into a single generalunion．Some tradeunion officials have to be re．elected regularly；others are elected，or even appointed，for life．Trade union officials have to workwith a system of“shop stewards”(工厂工人代表)in many unions，“shop stewards”being workers elected by other workers as theirrepresentatives at factory or work level． Why is the trade union power crucial in Britain
