Have you ever been to India? Yes, I went there last year. Have they ever flown on a plane? Yes, they travelled to Argentina last year. Has Sue sent the letter yet? Yes, she posted in yesterday. The newspaper printed an article about them last week. Yes. I know. They've been raising £6 million for charity so far. I haven't been seeing Tina for a long time. Really? She was volunteer centre this morning. John looks tired! He's been working at the charity event for three hours now. How long have you been waiting in the queue? Oh, for about ten minutes now. Is Jane still at the homeless shelter? Yes, she's been volunteering there all day.
