On this International Day of Persons with Disabilities, let us all commit to work together to tackle the obstacles, injustices and discrimination that persons with disabilities experience.
老师您好，let us·····是祈使句，let是动词，commit也是动词。怎么两个谓语动词在一个句子里？糊涂了
let us do sth. do sth为不带to的不定式作宾补。这应该是你在中学学过的内容。感官动词和使役动词make,have, let后作宾补的不定式不带to。
