It beats me (how, why etc.)
- (informal) I cannot explain, understand, accept something
It beats me how anyone can act in such an irresponsible way.
It makes no odds
- (informal) it makes no difference, it does not matter
It`s the same price whether you fly on a weekday or at the weekend, so it makes no odds which day you choose to travel on.
It`s a bit off
- (informal) it is not a fair or correct thing to do/way of doing things. Expresses a complaint about someone`s behaviour
Honestly, I do think it's a bit off, pushing all this work onto me while you go off enjoying yourself.
It`s a wonder (that)
- it is very surprising (that)
I forgot to lock the car and left it out all night. It's a wonder that it wasn`t stolen.
It`s anyone`s/anybody`s guess
- it is not possible to predict what will happen, one cannot know beforehand what the result will be
'Who do you think will win the election?' 'At the moment, it's anybody's guess. The candidates all have equal chances.'
It serves you etc. right
- it is a just punishment
'Tom failed his exam yesterday.' 'Well, it serves him right. He never does any work.'
As it is
- as the present / existing situation is
'How long will she have to stay in bed, doctor?' 'Well, as it is, a week at least.'
As it were
- one might say, one might describe it this way
The congress in Leeds was very relaxing, and my husband accompanied me, so it was rather like an extra holiday, as it were.
It can't be helped
- it is unfortunate, but no one can change it
'How depressing! Rain every day of our holiday.' 'Well, it can't be helped. We'll just have to make the best of it.'
