问题     In a seeming contradiction, the growth of computer-augmented work will probably create a need for less-skilled workers rather than the reverse. While early computers required much knowledge and skill to operate, comprehensive software packages have virtually eliminated the requirement for technical knowledge.
    Indeed, advanced software may lead to a decreased need for certain job-related skills. For example , word processing has reduced the need for secretarial typing accuracy, since mistakes can be corrected quickly and easily with no trace of correction. Spell-checking programs can be relied on to prevent common mistakes, thus decreasing the need for that language skill. We have already encountered cashiers who have no need to compute a customer’ s change. Instead, they merely enter the purchase amount and then the amount offered in payment. The machine calculates the change and, in some cases, automatically dispenses it.
    This effect is seen in more complex jobs, too. Nurses in intensive-care units often monitor several patients from a central station. Digital readouts continuously report patients’ vital signs. A-larms sound if values exceed an expected range. Despite the obvious advantages computerization has brought to both patient and staff, some health-care professionals are concerned that they may be losing important " soft" skills. The most important of these may be the intuition born of experience acquired in personally observing hundreds or thousands of patients. The look in a patient’ s eyes, the coloring of skin and the appearance of pain or restlessness are among many indicators used by medical personnel to anticipate changes in patient condition. These cannot be captured on a digital display.
    It cannot be denied that computers have made great contributions to productivity, nor would any reasonable person encourage scrapping the technology. However, we must pay more attention to human needs, and to the long-range effects of making jobs less interesting and decreasing skill requirements.
It can be concluded from the passage that the computers’ contributions to productivity are undeniable, ______.
选项 A、and more contributions are expected
B、so is the human dependence on them
C、but their consequent effects are worth considering
D、but we can abandon them for the sake of human needs
答案C
解析 文章最后指出不可否认computers have made great contributions to productivity，但是我们必须加强对human needs以及这样会带来的一些负面影响的关注。这就是说需要仔细思考衡量计算机应用会带来的后果。
