请教一句英语的语法问题
All anyone has to do is jump on-board and commit to working the opportunity in the manner that it is being presented to them.
Q1:jump 和commit是不是词形不正确啊?是不是需要加上-ing变成动名词?否则如何解释与is的连用?
Q3:manner在这里是什么意思?
Q2:that it is being presented to them是什么从句,修饰谁?them是指anybody吗?

A1:确实不对,可以把两个动词分别加上ing或者在jump前面加上一个介词to
A2:manner在这里的意思是“以某种方式”
A3:此为同位语从句,是对manner的解释说明,them 指的是anyone
