2018广西柳州中考招生实施方案政策解读
2018广西柳州中考招生实施方案政策解读导读:本文2018广西柳州中考招生实施方案政策解读,仅供参考,如果觉得很不错,欢迎点评和分享。
2018年普高招生方案出炉啦!柳江区中考毕业生可报读市内任一高中啦!有一个多月的时间中考将举行,柳州市今年中考和普通高中招生有什么变化?5月11日,柳州市教育局举行新闻发布会,公布柳州市2018年初中学业水平考试和高中阶段学校招生工作方案。
柳江区中考首次纳入市属管理柳江撤县设区后,从2018年起,柳江中学、柳江实验高中、柳江区职业教育中心纳入市属管理,面向市区范围招生。
设立柳江考区,柳江区的初中学校学业水平考试工作由柳江区教育局负责组织实施;柳江区户籍初中毕业生统一参加市区的招生录取,招生录取工作由市招生考试院负责组织实施。
由此而变化调整的就是原柳州市区(含新区)的初中毕业生除了可以报读原市属的高中学校外,今年还可以报读柳江中学、柳江实验高中、柳江区职教中心,同时柳江区的初中毕业生也可以报读市区任何一所高中学校。
音乐、美术拟加入中考往年的初中毕业升学考试科目包括语文、数学、英语(含听力)、物理(含物理实验)、化学(含化学实验)、思想品德、历史、体育与健康、地理、生物、信息技术等11个科目。
初中学业水平考试涵盖国家《义务教育课程设置实验方案》规定的全部科目,包括语文、数学、英语(含听力)、物理(含物理实验)、化学(含化学实验)、思想品德、历史、体育与健康、地理、生物、信息技术、音乐、美术等13个科目。
经柳州市教育局研究决定,新增的音乐和美术考试拟从2019年毕业年级开始实施,采取过程性与终结性考查相结合的形式,以纸笔开卷考试和技能考试相结合的方式进行。
具体办法另文下发。
普通高中招生人数增加较大2018年自治区下达柳州市高中阶段招生总数为36100人(其中普通高中招生任务数23000人,中职全日制招生任务数10600人,非全日制招生任务数2500人。
)。
2018年柳州市高中阶段招生目标总数拟定为25055人,比去年计划增加1980人,比今年自治区下达任务数增加2055人。

But usually people would accept tame(温顺的) and loyal(忠诚的) animals as pets rather than dangerous ones such as a lion,a tiger or a snake.People love pets and take good care of them. The owners usually regard pets as good friends and some even consider them as members of the family.

We often hear that a pet dog saved the owner's life or traveled thousands of miles to return home. Such stories often make pets more lovely.Some pets can also be trained to help people with some special work.

Some pets like dogs or snakes may hurt people without any warning. Some people may become ill after being hurt because of the virus carried by the pets.
