they do need you
do 是对need 的强调.表示的确.do 可以强调谓语动词.
I do love English .

您好，do 在这里表示强调，意思为他们确实非常需要你。在这类句子中，时态和第三人称单数等变化都在do上体现，后面的动词都用原形。

do起到加强语气的作用

do是加强语气，他们确实需要你的意思
不加只表示他们需要你

在意义上来讲是完全一样的在英语中前一句在动词前再加助动词的用法表示语气上的强调
“他们确实需要你”
在电影“小飞侠”中有一句台词“I do believe fairies ”就是这样的用法

助动词do可以放在原形动词前面表示强调，意思是：的确。
