plastic

Compared meaning: easily influenced (adjective).

比较义项：易受影响的（形容词）。

• plastic 本词

  Describes a mind or character that is naturally moldable and open to new ideas, especially in children; formal or literary in tone, and not followed by 'to'.

  形容人的思想或性格天生具有可塑性，容易接受新观念，尤指儿童；属正式、文学用语，后面不接“to”。

  A child's mind is still plastic, absorbing new ideas and habits.

  孩子的思想还很有可塑性，能不断吸收新观念和新习惯。

• susceptible

  A common everyday word for being easily affected by something specific, such as an illness, emotion, or influence; almost always followed by 'to'.

  常用词，指容易受到某种具体事物（如疾病、情绪、影响）的影响；几乎总是后接“to+名词或动名词”。

  Young children are more susceptible to common colds in winter.

  幼儿在冬天更容易感染普通感冒。

Plastic and susceptible both mean easily influenced, but differ. Plastic describes a mind that is naturally moldable, and is not followed by 'to'. Susceptible is everyday, for being affected by something specific, usually followed by 'to'. This excludes plastic meaning 'made of plastic'.

这两个词在“容易被影响”这一点上意思相近，但语气和用法不同：plastic 强调思想或性格像可塑的材料一样容易被塑造，多用于书面语，不接“to”；susceptible 是日常用词，强调对某种具体事物的易感性，常接“to”。这里不比较 plastic 常见的“塑料的、塑料”这一义项。
