英语翻译compared with almost twice this number in Northern Irela

英语翻译
compared with almost twice this number in Northern Ireland and Scotland.
twice this number in Northern Ireland and Scotland前面少了一个北爱尔兰和苏格兰的数值名词吧?
应该是北爱尔兰和苏格兰是威尔士13% 的两倍,请分析一下句子成分,13% of children in Wales主语
achieved 谓语the basic level of exposure 宾语
请分析compared with almost twice this number in Northern Ireland and Scotland.
尤其是twice this number

请分析compared with almost twice this number in Northern Ireland and Scotland.
尤其是twice this number

先去掉修饰部分句子变为compared with this number：和这组数据对比
almost twice 副词
你把twice的位置划错了,不应该和this number 粘一起,应该和前面的动词 compare一组
