综上所述，英语作为一种世界语言，在过去的几十年里，语言发生了显著的变化，研究人员发现这些变化不仅来自英语本身，也来自其他因素。本章试图概述需要考虑的问题，并通过言下之意，指出政策制定者应该承担责任的问题。什么类型的评估对于预期的目的是必要的，以及它可以被期望衡量的是应该首先考虑的问题。为了成功地使用语言测试来进行迁移和公民身份测试，定义策略的人必须在决定使用测试之后，在几个方面与测试提供者一起工作。这些变化将影响语言教学和评估的语言相关变化。评估是收集学生学习证据的实践。过去，对母语为英语的母语人士进行的英语测试或评估仍是标准的语言，而对母语为英语的人来说，这是一个很好的评价标准，反之则不符合标准的学习目标。语言测试和评价现在发生了变化，设定了最高的标准，从距离和差异的角度评估了最高标准的评价，然后通过内容分析来观察研究的对象和进展。语言评估也基于不同因素的变化，语言评估的地位在世界上更为重要，因此，语言学家、教育者和测试评估者应更加关注语言评估的优势和局限性，并掌握这些变化，然后采取有效的措施。
加拿大商业论文代写:英语的变化
To sum up, English as a world language, in the past few decades a significant change about the language, researchers have found that these changes not only from English language itself, but also from other factors. This chapter has attempted to outline the issues that need to be considered and, by implication, the issues for which policy makers should take responsibility. The questions of what type of assessment is necessary for the intended purpose, and what it can be expected to measure should be considered first. For the successful use of a language test for migration and citizenship purposes, those who define the policy must work with the test providers on several aspects after the decision to use a test has been made. During these changes will impact on language -related changes in language teaching and assessment. Assessment is the practice of collecting evidence of student learning. In the past, the English test or assessment still to the native English speakers of the language for criteria, which language closed to the native English speakers is a good standard of evaluation results, and vice versa is not up to the standard learning objectives. Language testing and evaluation is changed now, set the highest standards and evaluate the assessment of the highest standards from the distance and differences, and then view the object of study and progress through the content analysis. Language assessment also based on the different factors is change, and position of the language assessment is more important in the world, therefore, linguists, educators, and testing evaluators should pay more attention on the advantages and limitations of the language assessment, and to grasp these changes then take effective measures.
