Gap-filling Directions: Fill in the blanks in the following paragraph. (Chris sees Mr. Jay Twistle outside of the office building and strike up a conversation.) JAY TWISTLE: Taxi! CHRIS GARDNER: Mr. Twistle. JAY TWISTLE: Yeah, hi. CHRIS GARDNER: Hi. Chris Gardner. JAY TWISTLE: Yeah, hi. Listen. What can I do for you? CHRIS GARDNER: I submitted an application for the intern program about a month ago ... and I would just love to sit with you briefly ... JAY TWISTLE: Listen, I’m going to Noe Valley, Chris. Take care of yourself. CHRIS GARDNER: Mr. Twistle. Actually, I’m on my way to Noe Valley also. How about we s 1 a ride? JAY TWISTLE: All right, get in. CHRIS GARDNER: All right. So when I was in the Navy, I worked for a doctor who loved to play golf, hours every day ... and I would actually p 2 medical procedures ... when he’d leave me in the office. So I’m used to being in a p 3 where I have to make decisions and ... Mr. Twistle, listen. This is a very important ... JAY TWISTLE: I’m sorry. I’m sorry. This thing’s i 4 . CHRIS GARDNER: I can do it. JAY TWISTLE: No, you can’t. No one can. That’s bullshit. CHRIS GARDNER: No, I’m pretty s 5 I can do it. JAY TWISTLE: No, you can’t. CHRIS GARDNER: Let me see it. Give it here. Oh, yeah. Oh, wow, you really m 6 it up. JAY TWISTLE: Sorry. CHRIS GARDNER: It looks like it works around a swivel, so the center pieces never move. So if it’s yellow in the c 7 , that’s the yellow side. If it’s red in the center, that’s the red side. JAY TWISTLE: Okay. CHRIS GARDNER: So ... You can s 8 down. JAY TWISTLE: Listen, we can drive a 9 all day. I don’t believe you can do this. CHRIS GARDNER: Yeah, I can. JAY TWISTLE: No, you can’t. CHRIS GARDNER: Yes, I can. JAY TWISTLE: No, you can’t. I’m telling you, no one can. See? That’s all I ever do. You almost have this s 10 . Holy cow. You almost had that one. CHRIS GARDNER: I’m gonna get it. JAY TWISTLE: Look at that. You’re almost there.
