Hello evrybody.
Please:
1) I want to speak in my class about the use of "unless" and what I studied and found was that it can be used only with conditional type 1.But I found that it can be used with type 2 (unreal condition) and at the same time I found elsewhere that it can be used with both types 2+3!!! so please in which cases "unless" can be used? and in which cases it can not replace 'if not"?
2) What about condional type 2, we know that and were taught that with "to be" we use "were " with all persons "If I were/you were/he were/it were.....) but I found this and am puzzeled: a) she promissed to work harder if she wasn't expelled....b) I wouldn't eat that food if I wasn't hungry!!!!!
THANK YOU for any help
