—The research on the new flu virus vaccine is challenging and demanding. Who do you think can do the job?
—________ my students have a try?
A．MayB．Must
C．WillD．Shall
D
D 考察情態(tài)動詞。句義：新病毒疫苗的研究要求高，又有挑戰(zhàn)性。你認為水能做這個工作呢？我的學生可以試一試嗎？may一般不喝第三人稱構(gòu)成疑問句。Must必須，不符合文義。Shall用于第三人稱的疑問句中，表示說話人征求對方的意見或者項對方請示。故D正確。
