矛盾.在哲学中：名词[Philosophy] (a) contradiction 形容词contradictory; conflicting; incompatible; discrepant; repugnant 动词to conflict; to contradict; to be at variance (with)冲突：名词conflicts,clash of opposing forces，contention，collision动词collide with， clashed with例句示威者与警察发生冲突。 Demonstrators police.尴尬：名词embarrassment,形容词awkward; embarrassed; discomfiture; [例句]It was an embarrassing situation, but they carried it off well.这是一个尴尬的局面，但是他们成功地应付过去了。分歧：differences，divergence[数] bifurcation; ramification; branching; [例句]China believes that there are rights and wrongs involved in the disputes between third world countries中国认为第三世界国家的分歧是有是有非，有曲有直的。
翻译这种句子时候首先要弄懂所给单词的词性和意思。collision是一个名词(可数名词)，解释为“碰撞、冲突、（意见，看法）的抵触”。when you and your friends have collision 或者用there be 的句型，即 when there is a collision between you and your friend两者都可以。若理解请采纳。
collision n.碰撞，冲突come into collision (with) （跟……）冲撞或产生冲突；in collision 相撞，在冲突中 when you come into collision with your friends【数学之美】很高兴为你解答，不懂请追问！满意请采纳，谢谢！O(∩_∩)O~
