bone of contention，和 apple of di

还记得之前学习过的习语 apple of discord 吗？它跟 bone of contention 意思很类似，意为”争议的焦点；争执所在“，寓意：

the subject of a dispute

争论的主题

the subject of argument or disagreement

争论或分歧的主题

something that people have been arguing about for a long period of time

人们争论了很久的东西

例如：

A serious bone of contention between the landowners and the developers was the compensation price for the land.

土地所有者和开发商之间的一个严重争论焦点是土地的补偿价格。

The fact that Peter did not go to medical school is a bone of contention between him and his father.

彼得没有上医学院这一事实是他和他父亲争论的焦点。

解析：连词 that 引导的同位语从句，与先行词 the day 是同位或等同的关系，

一般情况下同位语从句跟在某些名词（如news，idea，fact，promise，hope，message 等）的后面，用以说明该名词所表达的具体内容。

After my grandfather died, his will was a bone of contention in the family.

我祖父去世后，他的遗嘱成了家里争论的焦点。

解析：动名词短语 playing game on new smartphone 作主语。

That beautiful girl has now become a bone of contention between two best friends of the college.

现在那个漂亮的女孩成了大学里两个最好的朋友之间争论的焦点。

解析：between 和 and 组成并列连词，常用于连接两个事物，也可以用于连接超过两个的事物来清楚的列出每个独立的项，例如：

There has been a marked increase in trade between France, Germany and Italy.

法国、德国和意大利之间的贸易明显增加。

现实生活中，人们都会因纷繁复杂的事情而进行争论或争执，有的时候愈演愈烈，造成两败俱伤。一切以和为贵，如果有法可依，就依法办事，如果无法可依，就仲裁调解。
