IB课程EE怎么选科
毫无疑问，如何写EE是这几年IB课程问的比较多的问题，很多同学家长对理科科目的EE感到无从下手，写好EE是一个需要长期积累的过程，删删减减批改修改后拿出最后的文章你就会发现你获得的不只是这一篇文章。本期小编来给大家总结一下IB课程的EE如何选科才能放大优点~
IB课程的EE该怎么选科
选HL科目是默认常规
EE是一个比较接近于你大学写Essay时候的INDEPENDENT RESEARCH，需要学生有Personal Engagement，但要根据自己能力，第一年不能拿6、7分的科目慎选，EE涉及的选科内容大于普通IA，如果不擅长结果半途换题实在不可。
最好选择你最喜欢的学科
写EE的过程较为漫长，兴趣是孩子最好的老师，需要独立思考且深入研究，要有思路和实践方法。
EE灵感最好取自生活细节
不同于IA只是单纯的研究问题，EE是需要有学术层次的思考，IB就是想拿EE来引导大家不论是自然还是人文艺术，值得深究的是生活中的细节。研究课题要有可行性，需要大量数据材料的辅助。
IBO官网上有整理非常多的各科EE范文，很多孩子们可能不知道，或者没有时间去搜索，这次就给大家下载好整理好啦，家里有需要的孩子们可以存一份哦～
Figure 2：Acetic Anhydride
As have discussed in the introduction,acetic anhydride exhibits numerous hazardous effects and
can be used to produce heroin.Additionally,since it is a Category IVsubstance-which refers to a group ofstrictly regulated chemicals that can be used to produce illicit narcotics in Thailand-the compound is not an ideal candidate for a green synthesis and thus prompted me to look for possible replacements. Observing that compounds must contain the acetyl group,I found two possible acetic anhydride replacements:acetyl chloride(Figure 3)and acetic acid (Figure 4). The acetyl groups are highlighted in red.
However, after further investigation,I found out that acetyl chloride like acetic anhydride,is also a Category IV substance.Being category IV substances they are illegal for normal uses in Thailand(Chaninat).While quantitative conclusions of these two substances could not be drawn.
