■ strength

作为可数名词，表示“一个个的优点（强项）”，与 weaknesses（一个个的缺点或弱项）相对。

• He stood by the gist of his assertions that God imbued each race with different strengths.他坚持他主张的要旨，认为上帝赋予了每个种族以不同的优点。
• "Describe your strengths and weaknesses," said the interviewer.面试者说，“请说明一下你的强项和弱项。”

译成“强项”似乎比译成“优点”更好些，因为这里指的主要是工作能力（“出活”）而不是个人的品质。
