Certainly dustmen prefer to be known as "Reuse Collection and Disposal Officers". You may think that this is rather    36 , and it is better to call a spade a spade. But dustmen can be as    37  as people of any other occupation, though we must     38   that their job is not a    39    one in the world. We often take dustmen for granted. Perhaps because they usually come very early in the morning, before most people are     40   .We are likely to forget their     41   .Our dustbins are    42   regularly, but we    43    stop to think about the men who do this. However, it is one of the most important jobs in the world, and when there are no dustmen to    44   the rubbish, the general    45   soon becomes aware that something is wrong. Recently, the dustmen of England went on strike for higher wages.
During the first few days it was regarded as a    46  .But when the first two weeks had passed, and the dustbins were overflowing in nearly every backyard in the country, the joke did not seem so    47   any more.    48   the strike continued, people could not    49   the hills of rubbish around their dustbins, and they looked for other places in which to    50  it. Even Leicester Square, in the heart of West End of London, was    51   high with plastic bags full of smelly rubbish. This was a(n)    52   attraction that the people of London were not at all     53   to see. Even when the strike was over, it took several weeks for the country to get cleaned up completely. Perhaps now the English people appreciate the work of    54  dustmen rather more    55   and won't take them for granted any more.
