A friend of mine made such sentences:
Coming together is a beginning, working together is a process and staying together is a success. If every one can do all these, our school can become an outstanding institution.
My doubt is, can the underlined words be 'all this'? In my opinion, the first sentence is a group of actions.
Coming together is a beginning, working together is a process and staying together is a success. If every one can make all of these work, our school can become an outstanding institution.
'All these' is fine; 'all this' appears possible.
Context is always important; labelling is rarely important.
Why is 'all this' possible?
You've answered your own question in your first post: "the first sentence is a group of actions." It's one group of actions. If everyone can accomplish this group of actions, the school will be outstanding (and probably a little boring).
PS: 5jj and I crossed in posting.
I agree that "all this" is possible for the same reasons.
Here's another example:
- While I'm at work, please do the washing up, hoover and clean the oven?
- I'll try!
- If you can do all that, I'll buy you a huge bar of chocolate!
Although the person is being asked to do three separate things, they can be viewed as one list of things to do. Consequently, I would happily use "that" which is singular, as is "this". I would be unlikely to say "If you can do all those, I'll buy you chocolate".
Thanks, every one, for your enlightening explanations.
