EWRT1A-68: moving of Bedford exercises

Just a reminder that I've moved around the Bedford exercises due for the next two weeks.

For Wednesday, November 19th, please do exercise 11-1, mixed constructions (do all ten).

That means that the modifiers exercises will be bumped down to Monday, November 24th. Do exercise 12-1, 1-5 and exercise 12-2, 1-5.

And for Wednesday, November 26th, do active verbs exercise 8-1, 1-5.

Everything else on the syllabus stays the same.
