阅读下面这篇短文，短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第2，3，5和6段每段选择1个正确的小标题；(2)第27～30题要求从所给的6个选项中选择4个正确选项，分别完成每个句子。 Robots 1 The
most sophisticated (先进的) Japanese-robots, which have vision systems and work at
very high speeds, are still based on American designs. Studies of robots,
particularly computer control software, are considered to be generally less
advanced in Japan than in America or Europe. 2 Although industrial
robots were originally developed as devices for simply handling objects, today
their commonest uses are for more skilled work like welding (焊接), spray-painting
and assembling components. 3 In Britain, robot sales appropriately
peaked in 1984, but have been declining ever since. This is partly because
British wage rates are too low to make robots financially attractive and partly
because engineers now have more experience with robots and are more aware of the
difficulties of introducing them effectively. 4 It has been calculated
that a robot uses on average about 100 times more energy than a human to do an
equivalent job. 5 It is estimated that 20% of all comic book heroes in
Japan are robots. This is an enormous number because comics are so popular that
they make up a third of all material published in Japan. 6 The
reliability of robots is measured in their MT. BF. or mean time between
failures. This has risen from about 250 hours in the mid-1970s to about 10,000
hours today (equivalent to working 18 hours a day for two years). One way robot
manufacturers have increased reliability is to test every single component they
buy, instead of the normal procedure of just testing a small sample. 7
The biggest single benefit of introducing robots claimed by Japanese
companies is that they increase quality control. Once programmed, the robots can
work more accurately and consistently than humans, who can get tired and
bored. Paragraph 2 ______.
A Ongoing Research
B Extension of Use
C Robot Heroes
D Greater Reliability
E Falling Demand
F Hidden Danger
