行为动词：一般为need to do sth ,用法与like to do sth 相同,所以对行为动词提问的时候为“what do you need ”等,有人称变化,比如he needs to go to school
情态动词：此时need的用法与can ,should .等相同,没有人称变化形式,后跟动词原形,比如说he need go to school ,对情态动词提问直接是“need you go to school”
这道题目中,首先判断为一般现在时,所以排除A,如果选择B,表示need为情态动词,不需要第三人称单数,排除.选C,表明need为行为动词,因为是your friend ,所以为第三人称单数,要加S,所以选D
