Teaching Models
Ex. 1.Ask each other about the time.
| Model: | – What’s the time, please? – It’s ten sharp. – It’s a quarter past two. (It’s two fifteen.) – It’s half past eleven. (It’s eleven thirty.) – It’s twenty minutes to nine. (It’s eight forty.) |
Prompts: 7.30; 10.15; 12.00; 7.35; 4.03; 9.23; 3.57; 6.44; 2.10; 12.25; 5.00; 2.05.
Ex. 2.Practice reading the following dates aloud.
Model: 1.05.70 → My sister was born on the first of May, 1970.
19.4.94; 5.9.77; 26.8.63; 8.7.43; 26.3.55; 31.6.88 (GB)
4/19/94; 9/5/77; 8/26/63; 7/8/43; 3/26/55; 6/31/88 (USA)
Ex. 3. Here are some questions about the Channel Tunnel between Great Britain and France. Can you guess the answers? (Each of the answers is one of the numbers in the list below).
| 50 15,000 220 10 bn 575 1,200 10 45 |
1. What was the total cost of the project? (… pounds)
2. How many workers died during the project?
3. How deep is the tunnel below the sea-bed? ( … metres)
4. How many companies supplied equipment?
5. How long is the total amount of railway track in the tunnel? (… kilometres)
6. How long is the tunnel? (… kilometres)
7. How heavy were the drilling machines? ( … tons)
8. How many workers built it?
b) Now read this article from the Engineering Times and check your answers. Retell the text.
“The greatest engineering project ever”
The Channel Tunnel is not just one tunnel; it consists of three tunnels, each thirty miles (about 50 km) long. It is the second longest tunnel in the world. The longest is the Seikan tunnel in Japan, but the Channel Tunnel has a longer under-sea section. Fifteen thousand workers built it (ten died in accidents) and 1,200 companies supplied equipment. It cost ten billion pounds to build.
One team began drilling in France and the other in England. The biggest problem for the builders was ensuring that the tunnels met at exactly the same place under the sea in the middle of the Channel. The drilling machines were the heaviest ever made, each weighing up to 575 tons. In the opinion of Roger Dobson, Director General of the Institute of Civil Engineers, ‘The Channel Tunnel is the greatest engineering project ever.’
The tunnel itself is an average of 45 m below the sea-bed and has 220 km of railway track. It has the most sophisticated railway control system in the world, and will be the busiest railway track in Europe, with one train every three minutes.
Ex. 4.Julia Lock is the head of a department facts. Speak about her daily routine using the information below. Supply your own information if necessary.
Model: get up at 6.30 → Julia Lock usually (always, often) gets up at 6.30
Promots: get up at 6.30; have a shower at 6.40; start making up at 6.55; have breakfast at 7.30; leave home at 8.05; catch a train at 8.25; start work at 9.15; discuss plans for the day with the employees at 9.20; have a meeting with the boss at 10.00; have lunch at 1.00; meet with customers at 2.00; finish work at 5.15; arrive home at 6.25; have a shower at 6.40; have dinner at 7.00; watch TV (read, go out) after dinner; go to bed at 11.45.
Ex. 5.Convert the following British measures of distance to the metric system.
Model: 1 mile = 1.6 kilometres → One mile is equal to one point six kilometers (one kilometer six hundred metres).
| Miles | ||||||||||
| Kilometres |
Ex. 6.Do the following sums according to the Model.
| a) | Model: | 4 + 4 = Four plus (and) four is eight 2 x 2 = Two multiplied by two is four 5 – 1 = Five minus (take away) one is four 8 : 2 = Eight divided by two is four |
| 4 + 5 = 9 + 4 = 35 + 16 = | 18 – 10 = 54 – 28 = 146 – 92 = | 8 x 4 = 11 x 5 = 15 x 15 = | 72 : 9 = 12 : 6 = 144 : 12 = |
b) Model: 
an (one) fifth plus a (one) third is eight fifteenth
c) Model: 2.36 + 0.9 = 3.26 two point three six plus (nought) point nine is (=) three point two six
8.85 + 5.6 = 22.4 – 5.6 = 1.13 x 0.4 = 5.05 : 5 =
