"suggest"后面应该接 doing，而不是"to do"。例如：
1. I suggested going to the party tonight.
2. He suggested going out for a walk.
建议做某事：suggest doing sth.
建议某人做某事：suggest （that） sb. do sth.
注意：在某些情况下，"that"从句中的"should"可以被省略，直接使用"suggest sb do sth."的结构。例如：
1. I suggest we go out by car.
总结：
建议做某事：suggest doing sth.
建议某人做某事：suggest （that） sb. do sth. （通常可以省略"that"和"should"）
