给出一段英文文本并要求将其中的语法错误列出来。
The student sings good in the choir.
The correct version would be: "The student sings well in the choir."

The grammar error in the original sentence is the use of "good" instead of "well." "Good" is an adjective and should not be used to modify the verb "sing." "Well" is an adverb that should be used to describe the manner in which the student sings. Therefore, "the student sings well in the choir" is the correct sentence.
