Jake and Michael, two friends, are talking.

J: Hello, I (1) haven't seen you for ages.

M: No, it must be about two years since we last (2) met. What (3) have you done with yourself?

J: I (4) have done all sorts of things. Life (5) has been very busy lately. I (6) have started a new job at the sailing centre.

M: Really! Doing what?

J: Well, I (7) am teaching beginners' courses to school groups this term but when those (8) finish, I'll be teaching more advanced groups on holiday courses.

M: That sounds great. What about your old job at the tourist office then?

J: Well, I (9) worked there for ten years and I quite (10) enjoyed the job but I (11) wanted to do something different. I (12) had always enjoyed sailing in my spare time so I (13) thought it would be nice to do it for a job.

M: So how long (14) have you been at the sailing centre?

J: For about two months now. I'm sure I (15) am doing the right thing. It's a really enjoyable job. And what about you?

M: Well, I'm still at the Rembrandt Hotel. I (16) have been working there for fifteen years now. But I (17) have had a promotion so that's good. They (18) have given me the job of head receptionist.

J: Oh, that's good news.

M: Yes, it (19) makes me feel much better about work. I mean, I (20) have done a lot of different jobs at the hotel but I (21) have never had a job with this much responsibility before. I (22) worked on the reception desk for four years when I (23) started at the hotel – that was before they (24) moved me into the office – but I (25) was only a junior receptionist then so I just (26) did what I (27) was told to do.

J: So when (28) did you get the new job?

M: A month ago, after I (29) passed my intermediate exams in Spanish and German at the college. Did you know I (30) am doing language evening classes at the college for a while now?

J: No, I didn't realize.

M: Yes, I (31) decided that I (32) couldn't get any further at work without learning some languages.

A: And so you did! What a good idea.

News (1) has just come in that there (2) was an air crash somewhere off the south coast of England.

Relatives of most of the passengers and crew (7) have now been informed and many of them (8) have set off for the sea rescue base, but they (9) haven't been given much hope. Most of the passengers (I0) were on business.

Despite the problems that the government (11) have had in the last two years, it (l2) has somehow managed to stay in power. There (13) have been a number of scandals involving government ministers, including one rumour about the Prime Minister himself. It is said that he (4) had promised gifts to certain Members of Parliament in exchange for their vote before he (15) was elected leader. In spite of all this, the government (16) has maintained its position in Parliament and (17) claimed that this (18) has been the most successful term of office that a government (19) has ever had. This is rather surprising as they (20) came to power with only a small majority.
