I am having a trouble (with?/for?/about?) expaining grammatical problems to my friend. Alternatively, I don't know.
Here is the problem:
.....I didn't do anything much lately. (1)
.....that is the only that causes problems. (2)
Please explain with reference if you can.
I try to help my friend and I'd like to learn too.
When I read the two sentenses, I doubt they are incorrect.
I think that: (1) should be: I didn't do anything lately. Or, I didn't do much lately.
(2) would be: That is the only thing/reason that causes the problems. Or, That is the only thing/reason that causes problems.
I am not sure which (ones) of those are corrected.
My question is: Please correct and explain in detail even if you can give me some source of references would be great. Because if you correct the sentences without expaining, I will do the samething to my friend.
1. "I haven't done anything much lately" is acceptable in colloquial English. 'Lately' in an adverb that's used with the present perfect tense. Some people would object to "anything much" - you could leave out 'anything'.
2. There is a missing word in this sentence. One way to fix it would be to add an appropriate word:
"That is the only thing that causes problems." "The only" by itself doesn't mean anything.
