下列有关《三国演义》的表述正确的一项是(   )(2分)

A.在官渡之战中,曹操虽然实力较弱,但他知人善任;袁术虽然兵多粮足,但他优柔寡断,目光短浅。因此,曹操掌握了主动,烧了袁术的粮草,使得袁术兵败如山倒,逃回了翼州。

B.《三国演义》第三十六回中有“伏龙、凤雏两人得一,可安天下”之说,其中“伏龙”指诸葛亮,“凤雏”指徐庶。徐庶后虽被曹操用老母骗取,但终生不曾为曹操设一谋,因此后有“徐庶进曹营——一言不发”的歇后语。

C.刘关张于张角乱军中救了董卓,董卓却因三人出身低微极为怠慢,因此激怒了张飞,欲杀掉董卓,刘备关羽及时阻止。最后三人连夜引军投了别处。

D.“煮酒论英雄”一节里,曹操杀吕布后,带着刘、关、张三人回到许昌,谋臣劝说曹操早日赶走刘备,免得他日后做大来争位子。曹操说:“实在吾掌握之内,吾何惧哉?”这表明他对刘备没有丝毫的顾虑。
