     Over the last 25 years, British society has changed a great deal-or at least many parts of it have. 

  1  .

     Ideas about social class-whether a person is "workingclass" or "middleclass" -are one area in

which changes have been extremely slow.

     In the past, the workingclass tended to be paid less than middleclass people. The typical working

man would collect his wages on Friday evening and then, it was widely believed, having given his

wife her "housekeeping", would go out and squander the rest on beer and betting.

     The old style of what a middleclass man did with his money was perhaps nearer the truth. He was

and still is inclined to take a longerterm view. Not only did he regard buying a house as a most

important thing, but he also considered the education of his children as extremely important.    2  .

Only in very few cases did workers have the opportunity (or the education and training) to make such

longterm plans.

      3  . In a large number of cases factory workers earn as much as their middleclass supervisors (管

理者). Social security and laws to improve century, have made it less necessary than before to worry

about "tomorrow". Workingclass people seem slowly to be losing the feeling of inferiority(自卑感). In

fact there has been a growing tendency in the past few years for the middleclasses to feel slightly

ashamed of their position.

       4  .They generally tend to share very similar tastes in music and clothes, they spend their money

in having a good time, and save for holidays or longerterm plans when necessary. There seems to be

much less difference than in precious generations.    5  . As long as this gap exists, there will always

be a possibility that new conflicts and jealousies will emerge, or rather that the old conflicts will

reappear, but between different groups.

A.  Nowadays, a great deal has changed

B.  Both of these provided him and his family with security

C.  As a result, differences in lifestyles and attitudes came into existence

D.  However, we still have a wide gap between the wellpaid and the lowpaid

E.  In recent years, the workingclass people have begun to design longterm plans

F.  In some ways, however, very little has changed, particularly where attitudes are concerned

G.  The changes in both lifestyles and attitudes are probably most easily seen among younger people

某沟槽长335.1 m，底宽为3m，室外地坪设计标高为-0.3m，槽底标高为-3m，无地下水，放坡系数为1:0.67，沟槽两端不放坡，采用挖斗容量为0.5m³的反铲挖掘机挖土，载重量为5t的自卸汽车将开挖土方量的60%运走，运距为3km，其余土方量就地堆放。经现场测试的有关数据如下：

1．假设土的松散系数为1.2，松散状态容重为1.65/m³。

2．假设挖掘机的铲斗充盈系数为1.0，每循环1次时间为2min，机械时间利用系数为0.85。

3．自卸汽车每一次装卸往返需24min，时问利用系数为0.80。

(注：“时间利用系数”仅限于计算台班产量时使用)

[问题]

所选挖掘机、自卸汽车的台班产量是多少？
