==Infinitivo ou -ing?==

Às vezes precisamos decidir quando usar um verbo em sua forma:
<div class="well well-ex">
:::-ing (doing, singing)
</div>
:::ou
<div class="well well-ex">
:::infinitiva (to do, to sing).
</div>
Por exemplo, apenas uma das seguintes frases está correta. Qual?
<div class="well well-ex">
:::I dislike working late. (???)
:::I dislike to work late. (???)
</div>

<div class="well well-ex" style="width: 50%;"> 
    I was happy to help them.
    She will be delighted to see you.
</div>

2.1 Isto inclui too + adjetivo:
