Just a couple of common mistakes from my writing course today:
Example is not spelled exemple
Exemplary is not spelled examplary
Research is non-count. If you want a count noun with a similar meaning, try using “studies” or “tests” instead. “I completed research for the scientist.” OR “I completed three studies for the scientist.”
Have something with – I’ll have a burger with fries, please. Not have something to.
A student told me of a quote in Russian that shows a good attitude to failure: “He who doesn’t take risks doesn’t drink champagne.” I know of a quote from sports that means the same thing: “You miss all of the shots you don’t take.”
These and those: “These” talks about things we have already discussed, or the first of two groups. “Those” talks about the second of two groups. “These are good, but those are bad.”
