Today I'd like to introduce you to a Grammar site: The English Page, which is also listed in The Permanent Collection of sites in the right-hand column of this Blog.
At the beginning of our course, we were investigating Past Tenses: how to use the Past Simple and Present Perfect tenses correctly.
So, visit The English Page and in particular The Past Simple, and The Present Perfect.
When you have finished, try these exercises on the simple past and present perfect simple: exercise 5 and exercise 6.
When you do these exercises, you can get a 'hint' - a little help - for each question. Or you can check your progress. For each question, or space, do not worry if the computer says 'Sorry - try again', especially if you have not finished the entire exercise. Instead, watch to see if your percentage score increases. If it does, you are giving the right answers. If you give a wrong answer, your score won't increase, and whatever you wrote in the gap will be deleted.
As usual, after trying this site, please do leave a comment. You now know how to do this since I demonstrated Comments some lessons ago.
Next post: how to use the associated keyword feature in the Hong Kong Poly Concordancer. Try it yourself first: use it to research the different meanings of phrasal verbs.
For instance, how many meanings can you find for 'give up'?
