Question and short answer forms part 3. The past perfect simple tense. Hm, are you interested in Jackie? >> Well, she just sounds really cool. It seems like she knows a lot. Before she started working here, had she done other cool things? >> Yeah, she had done a homestay with the Eskimos in Alaska. >> No way, why had she chosen to do her homestay there? >> She had received a scholarship to study about the Eskimo culture. >> How had she won the scholarship? >> Well, she had designed a new machine that records whale sounds. [SOUND] >> Wow, I really have to ask her out. >> It's really amazing all the things that Jackie has done. We've learned a lot about her, we know that Jackie works in advertising now, but started working at the company about a year ago. Before that she lived with Eskimos in Alaska. That was possible because she received a scholarship before that. And she was able to win that scholarship because she had designed a special machine that records whale sounds. When we ask questions about past events that happened before another past time, we often use the past perfect form. Like when Linus asked, before she started working here, had she done other cool things? He asked this yes/no question to ask about things she had done in the past before working at the company which was a closer past time. How could you respond with a short answer to a question like this? You would either say, yes, she had or no, she hadn't. Great. As the conversation continued, Linus wanted more detailed information, so he asked WH questions like, why had she chosen to do her homestay in Alaska? He used the past perfect because he was asking about the decision she made to go to Alaska which happened before she started working at the company. Again, when Linus asked, how had she won the scholarship, he used the past perfect form asking about an even further time in the past. Did you notice the pattern in question form for the past perfect? If you're asking a WH question, begin with the appropriate WH word, plus had, then the subject, and then the past participle of the main verb. I hope you had a chance to watch all 3 parts of the question and short answer forms for the perfect tenses, thanks for watching.
