Hello everyone! I need your help. One of my books contains the following examples of the reported speech:
1. "Why is the world round?" asked the little girl.
The little girl wanted to know why the world
was round.
2. "Smoking is bad for you", the teacher told us.
The teacher explained that smoking
was bad for us.
I know that
we do not usually change a simple present tense
if the statement is always true. So, my questions are:
1) can I leave the present simple here unchanged, e.g. The little girl wanted to know why the world
is round.
e.g. The teacher explained that smoking
is bad for us.
2) OR maybe both variants - past and present simple - are possible here.
Thanks in advance.
If you can, please give some explanations.
