巧妙记忆
“all together” 和 “altogether”两者虽然读音一样，写法也有一定相似性，但两者在意思上是完全不一样的。
“all together”由两个单词在一起组成的短语，我们取“一起”即可联想到含义是“一起、一道、同时”，而“altogether”则是副词，完完全全是一个一个单词，联想到其含义是“完全地”，进而想到其所有含义“完全地、彻底地、总共；全部地；总的来说”。
这个记忆方法是不是很快就记住了两个知识点。
最后强调一点它们可以表达数目上：共有、共计；用在这个时候它们是可以通用的。
All together there are six new faces in the cabinet.
内阁现在共有6张新面孔。
