单项选择题
董某、陈某都和周某有仇，都伺机杀周某。一天，董某在周某的饭里放了老鼠药，按其投人的分量，不足以致周某死亡。恰在董某下毒后一会儿，陈某也在周某的同一饭碗里投下了砒霜，按其分量也不足以致周某死亡，但他们各自下毒的分量加在一起，导致了周某的死亡。下列关于董某、陈某的行为说法正确的是：
A．构成片面共犯
B．构成共同犯罪
C．以共同犯罪论处
D．各自单独构成故意杀人罪
答案
参考答案：D
解析：理由：本题考查共同犯罪的条件。 《刑法》第25条规定：“共同犯罪是指二人以上共同故意犯罪。二人以上共同过失犯罪，不以共同犯罪论处；应当负刑事责任的，按照他们所犯的罪分别处罚。”从此条可看出，构成共同犯罪，必须具备下列条件：(1)主体条件：必须是二人以上，包括二个以上的自然人；二个以上的单位；有责任能力的自然人与单位构成的共同犯罪。(2)客观要件：各犯罪人必须实施了共同的犯罪行为，包括共同实行犯罪；存在分工的共同犯罪行为。(3)主观要件：各共同犯罪人必须有共同的犯罪故意，即各共同犯罪人通过意思联络，认识到他们的共同犯罪行为会发生危害社会的结果，并决意参加共同的犯罪，希望或放任这种结果发生的心理状态。本题中，董某、陈某应属于同时犯，不属于共犯。因为他们没有共同实行犯罪的意思联络，而在同一时间针对同一目标实行同一犯罪，对于这种犯罪现象，刑法规定应以单独犯分别论处，而不能以共同犯论处。所以答案为D。
