易错句子The city's population grew mushroom in the 1990s.

正确表达The city's population grew like a mushroom in the 1990s.

mushroom 作形容词属于定语用法，不能单独充当状语去修饰动词，所以 grew mushroom 不成立。汉语“蘑菇式增长”可以直接用名词修饰动词，英语没有这种结构；表示“像蘑菇一样（迅速）增长”要用 like a mushroom 这样的介词短语，或改用名词定语 mushroom growth。

易错句子There was a mushroom like cloud in the sky.

正确表达There was a mushroom-like cloud in the sky.

英语中表示“像……一样的”前置定语，由名词加连字符再接 -like 构成合成形容词 mushroom-like，整体放在名词前。拆写成 mushroom like 时 like 会被当成动词或介词，句子结构错误。
