[单选题]不久前,“水电费纳入征信”的传闻引起了公众的广泛关注。从现有社会经济活动的精细程度看,征信这种数字式指标性评价,未必能穷尽经济生活中的所有可能性。疏忽、出差、留学、搬家、住院乃至因纠纷而暂停缴纳,均有可能造成水电费的拖欠,显然,这些突发状况未必就能准确体现“个人信用”。倘若将这些指标以一种窄口径列入统计,就有可能造成误伤。正因为突发情况多,作为社会服务部门,更要尽到足够的提示、通知责任,并提供充足、便捷的补救渠道。在相关准备不充分时,水电费纳入征信理应审慎推进。这段文字意在说明()
A.选取征信指标应做到谨慎合理

[单项选择]
In every language there are two great classes of words which, taken together, consist of the whole vocabulary. First, there are those words with which we become acquainted in daily conversation, which we learn, that is to say, from the members of our own family and from our familiar associates, and which we should know and use even if we could not read or write. They concern the common things of life, and all the goods in trade of all those who speak the language. Such words may be called "popular", since they belong to the whole people; and are not the exclusive possession of a limited class.
On the other hand, our language includes a large number of words which are comparatively seldom used in ordinary conversation. Their meanings are known to every educated person, but there is little occasion to use them at home or in the market place. Ou
A. "popular" words are essential to daily life
B. "popular" words are not regular in usage
C. "popular" words are convenient to use

[简答题]需要设备主人开展现场核查的电能表异常工单有哪些?
[单项选择]In the first year or so of Web business, most of the action has revolved around efforts to tap the consumer market. More recently, as the Web proved to be more than a fashion, companies have started to buy and sell products and services with one another. Such business-to-business sales make sense because business people typically know what product they’re looking for.
Nonetheless, many companies still hesitate to use the Web because of doubts about its reliability. "Businesses need to feel they can trust the pathway between them and the supplier," says senior analyst Blanc Erwin of Forrester Research. Some companies are limiting the risk by conducting online transactions only with established business partners who are given access to the company’s private intranet.
Another major shift in the model for Internet commerce concerns the technology available for marketing. Until recently, Internet marketing activities have focused on strategies to "pull" customers into si

[单项选择] (B)

I suddenly heard an elephant crying as though frightened looking down. I immediately recognized that something was wrong and ran down to the edge of the near bank. There I saw Ma Shwe with her three-month-old calf struggling in the fast-rising water and it was a life-and-death struggle. Her calf was floating and screaming with fear. Ma Shwe was as near to the far bank as she could get, holding her whole body against the rushing water and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.
There was a sudden rise in the water and the calf was washed clean over the mother’s body and was gone. Ma Shwe turned quickly to reach it and pressed the calf with her head and trunk against the rocky bank. Then with a huge effort she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment, she fell back into the river. If s
