before few weeks my friend said: "my job is boring"
I need to report his speech to third person, What should I say? and why?
- He said that his job is boring.
- He said that his job was boring.
If the situation didn't change you can either do backshifting or leave the verb as it is:
He said (that) his job is boring.He said his job was boring.
You can also leave out "that".
The second sentence. If the verb in the main clause ("He said that...") is in the past tense, the verb in the object subordinate clause should also be used in the corresponding the past tense. This is the sequence of tenses, the choice of the verb tense in the subordinate clause depends on the tense of the verb in the main clause. However, there are also some exceptions to the rule, e.g.:
He didn't answer the question because he doesn't speak English.
If the subordinate clause is attributive, comparative or the clause of cause (like in the above-given example), the verb in the main clause can be used in the present and future tenses.
