put a drug into the body
to push a liquid drug into a person's or animal's body with a needle
用法模式：
to inject [something] into [someone/something]
常见错误：
Learners sometimes say *"inject to"* instead of *"inject into"*, for example *"The doctor injected the drug to my arm"*. The correct preposition is *into*: *"The doctor injected the drug into my arm"*. Another mistake is using *"inject"* without an object, where *"give an injection"* is more natural, e.g. *"The nurse gave me an injection"* rather than *"The nurse injected"*.

用法模式：
to inject [code/data] into [a system/program]
