Question

it is too cold to go out replace the world in italics by clauses

Answer 1

It is too cold to go out.

The 'too+adjective+to' structure is used to say that something or someone is more than good, necessary, possible, etc. In simple words, 'too+adjective+to' structure is used to mean the negative sense of the given sentence. For example the meaning of the sentence ' It is too cold to go out.' is 'It is so cold outside that you can’t go out.'

So the words in italics should be replaced as shown below:

It is so cold outside that you can’t go out.
