下列关于许可证的有效期正确的为( )。

A.《出口商品质量许可证》有效期为3~5年

B.《食品卫生注册登记证书》有效期为3年

C.《进出口电池产品备案书》有效期为1年

D.《出口玩具质量许可证》有效期为5年

答案

参考答案:B,C,D

解析: 国家对重要出口商品实施出口商品质量许可证制度。这些重要的出口商品主要有:机械产品、轻工机电产品、陶瓷产品、纺织机械、玩具、医疗器械产品、煤炭、焦炭、烟花爆竹、冶金轧辊等。《出口商品质量许可证》的有效期按不同商品有不同的有效期,在有效期内,检验检疫机构对获证单位实行日常的检查监督。食品卫生注册证书和卫生登记证书有效期为3年,选项B正确;《进出口电池产品备案书》有效期为1年,选项C说法正确;《出口玩具质量许可证》有效期为5年,选项D说法正确。故本题应选BCD项。
[链接] 新教材对《出口商品质量许可证》的有效期没有规定明确期限。而2003年版教材规定《出口商品质量许可证》的有效期为3~5年,考生要以最新教材为准。
[解题误区] 许多考生误认为强制性产品认证与出口质量许可证是一回事,其实这种观点是错误的。根据国认证[2003]19号《关于对实施强制性产品认证制度的产品不再实施出口的质量许可制度的通知》规定,对于强制性产品认证目录内的产品,不再搞出口质量许可证。

The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana (大麻). That is the statement of researchers who have found that tapping away on a mobile phone or computer keyboard or checking for electronic messages temporarily knocks up to 10 points off the user’s IQ. This rate of decline in intelligence compared unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have described the phenomenon of improved stupidity as “infomania”. The research conducted by Hewlett Packard, the technology company, has concluded that it is mainly a problem for adult workers, especially men.

It is concluded that too much use of modern technology can damage a person’s mind. It can cause a constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand. The report also added that, in a long term, the brain will be considerably shaped by what we do to it and by the experience of daily life. At a microcellular(微蜂窝,微孔的) level, the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences.

Too much use of modern technology can be damaging not only to a person’s mind, but to their social relationship. 1100 adults were interviewed during the research. More than 62 percent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an e-mail and will even interrupt a meeting to do so. It is concluded that infomania is increasing stress and anxiety and affecting one’s characteristics. Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude.

The effects on IQ were studied by Dr. Glenn Wilson, a psychologist at University of London. “This is a very real and widespread phenomenon,” he said. “We have found that infomania will damage a worker’s performance by reducing their mental sharpness and changing their social life. Companies should encourage a more balanced and appropriate way of working.”
