Like any placebo, it must be dispensed with authority to be effective. Just as a doctor calls on the full power of autocratic suggestion by insisting that the patient take precisely this white capsule precisely three times a day before meals, Lozanov is categoric in insisting that the suggestopedic session be conducted exactly in the manner designated, by trained and accredited suggestopedic teachers.
这里的 that the suggestopedic session be conducted ... = that the suggestopedic session should be conducted ...即 that 引导的是宾语从句,该从句的谓语动词使用虚拟语气。
如果 insist 表示“坚持,坚持要求,坚决要求”,后面的宾语从句中,谓语动词要用现在时虚拟语气(即动词原形)或者“ should +动词原形”,后一种用法只用于英国英语。如果 insist 表示“坚持认为,坚持主张,坚持说”,后面的宾语从句的谓语动词要用陈述语气。
