教学是一种有明确目的的活动，这种目的性渗透到课堂教学中，并由每堂课的具体目标来实现。教学目标对于指导课堂教学实施具有非常重要的作用。制定教学目标是课堂教学设计的第一步，是教师完成教学任务所要达到的要求或标准。请你根据《义务教育英语课程标准》中的总体课程目标结构，以“PEP Primary English Students’ Book(小学五年级)上册Unit 5”一篇课文为例(如下)，设计一个五维度的课堂教学目标。 We are rabbits.

English learners are getting younger. A global survey of English for young learners, undertaken by the British Council in 1999, showed that the majority of countries in which English was taught in primary schools had introduced the innovation in the 1990s. Since then, the practice has become more widespread. In Europe, almost every country documented in the 2005 Eurydice survey showed an increasing percentage of primary pupils learning English during the years 1998-2002 (the most recent year for which data was available). Since 2002, the trend has continued apace. (a) One rationale for teaching languages to young children is the idea that they find it easier to learn languages than older students. (b) They are still developing physically and intellectually; their emotional needs may be higher, they are less able to take responsibility for their own learning. (c) One of the practical reasons for introducing English to younger learner is to ensure that they have longer time in their school careers to master the language; another is because the timetables in secondary schools now have too many competing demands. (d) There are many hazards attached to EYL, not least of which is that it requires teachers who are proficient in English, have wider training in child development, and who are able to motivate young children. Such teachers are in short supply in most countries, but failure at this stage may be difficult to remedy later. Translate the underlined part of the sentence in Paragraph 1 into Chinese.
