Like a basketball competition, each player is informed of their function in the competition, which someone takes responsibility for scores while another player keeps watching over the players in the opposite team and shield teammates from being “attacked”.

This is much like a real-life basketball game, in which players are instructed to play their designated roles, such as attackers and defenders.

▲ 原句中的Like a basketball competition 是个不合理的状语成分，不论此处的like是“例如”的意思，还是“像…一样”的意思。

1）如果是“例如”的意思，like之前应该有一个描述整体的词，like后是一个具体的例子，比如：developing countries like China。

2）如果是“像…一样”的意思，那么此句的结构“Like A，B如何如何”中A和B是在概念上一致（注意：不是相关就可以，而是要一致）的两个词，而原句中的 a basketball competition（事件）与 each player（人）概念不一致。

▲ inform的意思是“告知（信息）”，所以信息是information。这个句子中，队员不应该是“被告知信息”，而应该是“被指令去做某事”，所以该用instruct。

▲ role替代function。人的作用对应“role”这个概念更合适，物件的作用对应“function”。

▲ designated = “指定的”。

▲ 句子的简化。最明显的地方在于原句最后关于“得分球员”和“防守球员”的繁琐措辞被直接的两个单词所替代。

▲ 原句中的which引导的从句是基础性语法的错误，改成in which。
