—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(dòng)詞。句義：新病毒疫苗的研究要求高，又有挑戰(zhàn)性。你認(rèn)為水能做這個(gè)工作呢？我的學(xué)生可以試一試嗎？may一般不喝第三人稱(chēng)構(gòu)成疑問(wèn)句。Must必須，不符合文義。Shall用于第三人稱(chēng)的疑問(wèn)句中，表示說(shuō)話(huà)人征求對(duì)方的意見(jiàn)或者項(xiàng)對(duì)方請(qǐng)示。故D正確。
