为了安全用电请注意……

不能用白胶布来包扎电线包扎电线应用电业专用绝缘胶布,但有时因找不到绝缘布,有些人就临时用医用的白胶布或关节止痛膏来代替,这样做很危险,因为白胶布与关节止痛膏的绝缘效果都要差得多。慎用“多用插座”不少家庭用“多用插座”来满足越来越多家用电器接电源的需要。这样做虽然可以省去逐个安装插座的麻烦,但也给安全用电带来了隐患。因为“多用插座”及电线都有一的容量限度,几种家用电器同时使用会在“

无线寻呼的未来走向

1、数字寻呼机向字符寻呼机发展,字符寻呼机向多功能化发展。寻呼机不只是提供简单的呼叫服务,而是提供信息传送的通信工具。例如,从提供股市行情、天气预报、标题新闻等简单的信息到提供这些方面的详细信息,甚至能提供诸如小说广播之类的娱乐性服务,能够发送传真,图象等数据信息以及与体育、新闻、文娱等专用数据库和其它数据库联网使用以提供增值服务等。此外,还可使寻呼机为笔记本电脑、电子记事本及其它电子产品提供接口,实现一机多用。

Task Complexity and Second Language Teaching

In the past few years, the notion of task complexity has been receiving substantial attention in the field of second language acquisition. This paper explores task complexity from the cognitive perspective by analyzing two studies with Skehan＇s limited capacity hypothesis and Robinson＇s cognition hypothesis. The two studies, namely You-Jin Kim＇s （2012） and Mirdamadi and Jong （2015）, explore on how linguistic complexity affects language performance. Two hypotheses, Skehan＇s limited capacity hypothesis and Robinson＇s cognition hypothesis, explain the two studies from the cognitive perspective by predicting either that increasing task complexity reduces a pool of attentional capacity during task performance or that increasing complex tasks promotes greater accuracy and complexity of speech and writing. It is suggested that language teaching, syllabus designing in particular, should be based on the basis of task complexity.
