associate 的核心是「建立联系」——你把 A 和 B 绑在一起，让它们相互关联。可以是脑中的联想（associate summer with beaches），可以是现实的关联（be associated with health risks），也可以是人际关系（business associate = 合伙人）。所有义项都围绕「连接」这一动作。
释义
1
v.将…与…联系起来（associate A with B）
Most people associate red with danger or passion.
大多数人将红色与危险或激情联系在一起。
2
v.与…有关联（be associated with）
Smoking is associated with a higher risk of lung cancer.
吸烟与肺癌风险升高相关。
3
n.合伙人；同事
She introduced her business associate to the clients.
她把她的商业伙伴介绍给了客户。
语感
associate A with B = 主动联想；be associated with = 客观相关
联系关联合伙人（名）
两个动词结构：associate A with B（主动、心理联想，主语通常是人）——We associate success with hard work（我们把成功与努力联系起来）；be associated with（客观、被动，描述两事物之间的相关性）——Poor diet is associated with obesity（不良饮食与肥胖有关）。高考写作中，be associated with 是描述「相关性」的高频书面表达，比 be related to 更正式。
陷阱
⚠️associate with 方向易混
Many health problems are associated with sedentary lifestyles.
✗
许多健康问题将久坐的生活方式联系在一起
✓
许多健康问题与久坐的生活方式相关
许多健康问题与久坐的生活方式密切相关。
⚠️associate 名词义：合伙人 ≠ 朋友
✗
He invited his old associates to his birthday party.
他邀请了老朋友来参加生日派对。
associate 作名词指「工作上的合伙人/同事」，不用于描述私人朋友关系
✓
He invited his old friends to his birthday party.
他邀请了老朋友来参加生日派对。
