I think_____(memorize)the words of pop songs also helps a little.memorizing 为什么这么填?谢

memorizing the words of pop songs动名词短语做主语

首先,think为动词,memorize也为动词,不可能连着用,如i am going to school 一样,am 、go同为动词,则go+ing
此外,此句句式为宾语从句,memorizing在此作动名词,整句句式应为I think（ that）memorizing the words of pop songs also helps a little.that可省略
