As little boys and girls have a very good memory, they can learn a lot of English words by heart very easily. This will help them in their future English learning. While others don’t agree.

答案

这里的our class指的是班级的每一个同学,如果指班级这个整体,就要用单数.
因为at some agreement所在的句子是一句否定句,在否定句或疑问句中表示“一些”或者“任何”、“某个”,要用any来表示.希望我能帮助你解疑释惑.
