This paper primarily focuses on the major development of language testing since 1980s. Critical to testing is me concept of language proficiency or ability which consists two components of language competence (or language knowledge) and strategic competence. A communicative approach to testing is demanding to catch up with the new teaching concept and to measure a learner' s cornmunicative competence. Communicative language tests are intended to measure people' s ability to use language communicatively in a variety of real life situations. 展开更多

This paper introduces the high-speed electrical multiple unit (EMO) life cycle, including the design, manufacturing, testing, and maintenance stages. It also presents the train control and monitoring system (TCMS) software development platform, the TCMS testing and verification bench, the EMU driving simulation platform, and the EMU remote data transmittal and maintenance platform. All these platforms and benches combined together make up the EMU life cycle cost (LCC) system. Each platform facilitates EMU LCC management and is an important part of the system. 展开更多

From the perspective of test methods, this paper revisits the communicative testing features reflected in the Revised Syllabus of the BEC Handbook (2002) by carrying out detailed analyses of the Sample Listening of BEC Vantage. A table of the Sample Listening is then constructed by using Bachman's framework of test methods (1999). From the table and a layout of its components, this paper explicates the five communicative testing features embodied in the Revised BEC: authenticity, contextualization, communicativeness, overall ability and holistic, qualitative scoring method. 展开更多
