常见错误：
Learners sometimes say *"I am very select"* when they mean *"I am very selective"*. "Select" is usually a verb or a formal adjective meaning "of special quality," while "selective" describes the behavior of choosing some things and not others. Another mistake is saying *"He is a selective person"*; more natural is *"He is very selective"* or *"He is very selective about his friends."*

Learners sometimes confuse this technical sense with the everyday "picky" meaning. In science and medicine, "selective" usually means *"specific to certain targets"*, not that a person or organization is being choosy. For example, a "selective drug" is one that acts mainly on one receptor type, not a medicine that someone has carefully chosen.
