Ex 6
My cousin, Peter (have) has a dog. It (be) is an intelligent with a short tail and big black eyes. Its name (be) is Kiki and it (like) likes eating pork. However, it (never/ bite) never bites anyone; sometimes it (bark) barks when strange guests visit. To be honest, it (be) is very friendly. It (not/ like) doesn't like eating fruits, but it (often/ play) often plays with them. When the weather (become) becomes bad, it (just/ sleep) just sleeps in his cage all day. Peter (play) plays with Kiki every day after school. There (be) are many people on the road, so Peter (not/ let) doesn't let the dog run into the road. He (often/ take) often takes Kiki to a large field to enjoy the peace there. Kiki (sometimes/ be) sometimes is naughty but Peter loves it very much.
