1. 1. Time and Timetables Prathomsuksa 6
2. 2. Telling the Time
3. 3. How many seconds are in a minute? 60
4. 4. How many seconds are in an hour? 60
5. 5. Vocabulary
6. 6. clock a device for measuring and showing time, which is usually found in or on a building and is not worn by a person
7. 7. minute any of the 60 parts which an hour is divided into, consisting of 60 seconds
8. 8. quarter one of four equal or almost equal parts of something; ¼
9. 9. hour a period of 60 minutes
10. 10. midday 12 o'clock in the middle of the day
11. 11. a.m. ( ante meridiem) used when referring to a time between twelve o'clock at night and twelve o'clock in the middle of the day
12. 12. p.m. ( post meridiem) used when referring to a time in the afternoon or evening or at night
13. 13. Structure
14. 14. Subordinating Conjunctions A Subordinating Conjunction (sometimes called a dependent word or subordinator) comes at the beginning of a Subordinate (or Dependent) Clause and establishes the relationship between the dependent clause and the rest of the sentence. It also turns the clause into something that depends on the rest of the sentence for its meaning.
15. 15. Notice that some of the subordinating conjunctions in the table below — after, before, since — are also prepositions, but as subordinators they are being used to introduce a clause and to subordinate the following clause to the independent element in the sentence.
16. 16. Common Subordinating Conjunctions after if though although if only till as in order that unless as if now that until as long as once when as though rather than whenever because since where before so that whereas even if than wherever even though that while
17. 17. Example: The clock face doesn’t tell us if it is before or after midday. If it’s before midday and p.m. for after midday. When we reach an hour after the middle of the day, we start counting again at 1.
18. 18. minutes hand hour hand
19. 19. Telling the Time When we write down or say the time we use many ways. If it is exactly on the hour we say o’clock (of the clock). Sometimes we say that part of an hour or how many minutes have passed since the last hour, how long before the next hour.
20. 20. In this section we look at different ways of writing times for example, ‘7:45’ is the same time as ‘quarter to eight’ or 15 minutes to 8. On a clock face, this can be represented as shown here:
21. 21. Also remember that one hour = 60 minutes so that half an hour = 30 minutes quarter of an hour = 15 minutes three quarter of an hour = 45 minutes
22. 22. we use "past" to say times after the hour until half past, or 30 minutes past the hour. "to" to say times before the hour from 31 minutes until the full hour. Be careful! In English we use at night NOT in the night
23. 23. five to o’clock five past ten past ten to a quarter past a quarter to twenty past twenty to twenty-five to half past twenty-five past
24. 24. 12- and 24-hour Clocks
25. 25. This is a 12-hour clock. When we reach an hour after the middle of the day, we start counting again at 1. The clock face doesn’t tell us if it is before or after midday. We use a.m. (ante meridiem) if it’s before midday. p.m. (post meridiem) for after midday.
26. 26. An easier, neater way to record the time is the 24-hour clock. We carry on counting the hours so that 1.00 p.m. becomes 13:00, 2 p.m. becomes 14:00 and so on.
27. 27. 24 23 13 14 22 21 15 20 16 19 18 17
28. 28. To keep it simple, use two digits for the hour and two for the minutes past, separated by a colon like this: 07:45
29. 29. Time to do activity
30. 30. Task 1 1. Direction: Change these times to 24-hour clock times. e.g. If the time is p.m. in the 12-hour clock we add 12 to the hours. 7.15 p.m. = 19:15.
