Hi there,
Just little corrections:
It is not right saying:
That is flower beautiful.
The proper English should be:
That flower is beautiful.
or
That is a beautiful flower.
It is not correct to say:
There is 10 rules.
The correct is to say:
There are 10 rules.
As this is a long lesson I have just put some examples of the corrections needed here and I will be pleased to help in any more clarification.
Regards.
