问题描述：
I suggest she ( )her grandmother at least once a week.
填visit 还是visiting?
答
visit。像suggest这样表示建议的动词或名词后面的从句要用虚拟语气，其结构为suggest that sb (should )do sth,其中的should省略，但是动词原形不能变，所以这里应该填visit。
答
楼上两位的解释合一起就更详细了，suggest引导的宾从用虚伪语气，也就是从句谓语动词用shoul+动词原型，should可以省略，类似的动词还有demand.order等。
答
visiting
答
visit
suggest
I suggest that she (should)visit her grandmother at least once a week.
答
visit,suggest引导的是虚拟语气宾语从句,从句谓语用动词原型,属固定用法.
