[-1:15.00]When we say that someone must be something,
[-1:16.00]like must be tired or must be worried,
[-1:17.00]we are talking about an assumption that we are almost certain is true.
[-1:18.00]Now,when you hear a statement using almost certain,say the same thing using must.
[-1:19.00]For example,you hear... I'm almost certain Steven is tired.
[-1:20.00]And you say...        He must be tired.
[-1:21.00]You hear..            I'm almost certain Steven and Anne are worried.
[-1:22.00]And you say...        They must be worried
[-1:23.00]All right,let's begin.
[-1:24.00]I'm almost certain Steven is tired.
[-1:25.00]He must be tired.
[-1:26.00]I'm almost certain Steven and Anne are worried.
[-1:27.00]They must be worried.
[-1:28.00]I'm almost certain Steven is nervous.
[-1:29.00]He must be nervous.
[-1:30.00]I'm almost certain Jake's story is good.
[-1:31.00]It must be good.
[-1:32.00]I'm almost certain Connie has an interesting job.
[-1:33.00]She must have an interesting job.
[-1:34.00]I'm almost certain Mike and Jake are hungry.
[-1:35.00]They must be hungry.
[-1:36.00]I'm almost certain Maria is having a great time on her vacation.
[-1:37.00]She must be having a great time on her vacation.
[-1:38.00]Don't forget that you can also use must be
[-1:39.00]with a verb that ends in-ing
[-1:40.00]to show that you are almost certain something is happening.
[-1:41.00]For example,I saw Connie going into that restaurant at noon.
[-1:42.00]That was 15 minutes ago.She must be having lunch.
[-1:43.00]Now this time,you'll hear a situation and you say what must be happening.
[-1:44.00]For example,You hear...   Jake is very tired.
[-1:45.00]He's been sitting in a comfortable chair with his eyes closed
[-1:46.00]for a long time.
[-1:47.00]And you say...           He must be sleeping.
[-1:48.00]You hear....             Maria is on vacation.
[-1:49.00]She's been doing a lot of skiing
[-1:50.00]and eating in nice restaurants with Sam Finch.
[-1:51.00]And you say...           She must be having a good time.
[-1:52.00]OK,ready?Let's begin.Jake is very tired.
[-1:53.00]He's been sitting in a comfortable chair with his eyes closed
[-1:54.00]for a long time.
[-1:55.00]He must be sleeping.
[-1:56.00]Maria is on vacation.She's been doing a lot of skiing
[-1:57.00]and eating in nice restaurants with Sam Finch.
[-1:58.00]She must be having a good time.
[-1:59.00]The doctor to Connie's office is closed,
[-2:00.00]and I can hear the sound of her typewriter.
[-2:-1.00]She must be working.
[-2:-2.00]Rita went out today wearing her tennis racket.I wonder what she's doing.
[-2:-3.00]She must be playing tennis.
[-2:-4.00]The waitress in the restaurant served Maria and Sam their food.
[-2:-5.00]That was ten minutes agao.But they're not eating;
[-2:-6.00]they're talking and looking at each other.
[-2:-7.00]What's happening to their hot food?
[-2:-8.00]It must be getting cold.
[-2:-9.00]Now listen to Connie and Mike again.
[-2:10.00]This time they're talking about Steven.
[-2:11.00]So Steven won't be able to come in today.
[-2:12.00]That's OK.I have the schedules and the scripts.
[-2:13.00]I'll be able to manage while he's gone.
[-2:14.00]He won't be able to see Jake's story on archaeology.
[-2:15.00]We'll show it tomorrow either,Mike.

[-2:17.00]Where's Maria?
[-2:18.00]Today's Thursday.Maria won't be back until Friday.
[-2:19.00]I don't think she'll be able to see the story either.
[-2:20.00]Now listen and repeat.
[-2:21.00]Steven won't be able to come in today
[-2:22.00]Steven won't be able to come in today.
[-2:23.00]I'll be able   to manage  while he's gone
