productive.some experts claim the answer is to make jobs more varied.but do more various jobs lead to greater productivity？there are facts to suggest that while variety certainly makes the worker’s life more enjoyable，it does not actually make him work harder.as far as increasing productivity is concerned，then variety is not an important factor.other experts feel that giving the worker freedom to do his job in his own way is important，and there is no doubt that this is true.the problem is that this kind of freedom cannot easily be given in the modern factory with its complicated machinery that must be used in a fixed way.thus while freedom of choice may be important，there is usually very little that can be done to create it.another very important consideration is how each worker contributes to the product he is making.in most factories the worker sees only one part of the product.some car factories are now experimenting with having many small production lines rather than one large one，so that each worker contributes more to the production of the cars on his line.it would seem that not only is degree of the worker’s contribution an important factor，therefore，but it is also one we can do something about.to what degree does more money lead to greater productivity？the workers themselves certainly think this is important.maybe they want more money only because the work they do is boring.money just lets them enjoy their spare time more.a similar argument may explain demands for shorter working hours.perhaps if we succeed in making their jobs more interesting，they will neither want more money，nor will shorter working hours be so important to them.1.which of the following is the best way to make workers work harder according to the author?a.increasing their pay.b.giving them more spare time.c.making the work itself meaningful.d.replacing large production lines with small ones.解析：提高生产率可行又有效的方案是让工人意识到自己工作的重要价值；d仅是c中的一种操作手段。答案：c2.the reason why a worker cannot have freedom in doing the job in his own way is that ________. a.the machine is so badly needed that more of it should be boughtb.there are few production lines in factoriesc.the bosses can create very little freedom of choicesd.the machines must be operated strictly accordin（各种工作总结、计划、报告、作文模板，尽在一路高升范文网）g to instructions and rules解析：根据文章的第二段中第二、三句话可知答案。答案：d3.besides money，what may make

modern workersb.making jobs more interesting c.pushing workers to produce mored.how to improve labor productivity解析：作者站在雇主方的立场上为厂家出谋划策，以期在不提高待遇的情况下提高生产率，因此用push 很符合作者的立场。答案：c
