To get started, discuss the following questions with your group members: 1. Some learners produce sentences like * Did you enjoy the film which you saw it? Is there any explanation for this type of mistake? 2. What is the difference between (a) and (b)? Is (a) better than (b)? (a) That’s the person to whom I talked. (b) That’s the person I talked to. 3. How can we decide if the structure in (a) does or doesn’t need commas, as shown in (b)? (a) My friend who’s Japanese is coming. (b) My friend, who’s Japanese, is coming. 4. Aren’t who and whose just for people? Isn’t it a mistake to talk about a house whose roof is leaking and a dog who makes us laugh ? 5. Give the two sentences in (a) and (b), how do we decide which one is easier to learn? (a) I met a man who had a cat. (b) The man I met had a cat.
