3. ask questions of 4 different types: 1) ask general questions to the sentences: a) drawing consists of pulling metal through a die. b) finally the edges are sheared off to give the final dimensions. c) the metal is stretched just beyond its yield point (2 to 4 percent strain) in order to retain the new shape. d) bending can be done by pressing between two dies. 2. ask alternative questions to the sentences: a) products may have a complex cross section. b) the most common rolled product is sheet. c) density is measured in kilograms per cubic metre. d) heat is lost by conduction through the base metal. 3. ask special questions to the sentences: a) resistance welding is widely employed in many fields of sheet metal or wire manufacturing . b) in 1896 hall in america and heroult in france discovered a molten solution capable of yielding aluminium under electrolyses. c) silica dissolved during the extraction process must be eliminated from the solution. d) the processes of welding can be divided into two main groups - pressure welding and heat welding. 4. ask disjunctive questions to the sentences: a) upsetting involves a flow of the metal back upon itself. b) such inclusions can be avoided by proper manufacturing procedures. c) welding processes are classified according to the sources of heat and pressure used. d) fusion welding is more effective with alternating current. 60

1)  General questions:

a) Does drawing consist of pulling metal through a die?

b) Are the edges sheared off to give the final dimensions?

c) Is the metal stretched just beyond its yield point (2 to 4 percent strain) in order to retain the new shape?

d) Can bending be done by pressing between two dies?

2. Alternative questions:

a) May products have a complex or simple cross section?

b) Is the most common rolled product sheet or strip?

c) Is density or viscosity measured in kilograms per cubic metre?

d) Is heat lost by conduction through the base or precious metal?

3. Special questions:

a) Where does resistance welding widely employed?

b) When did Hall in America and Heroult in France discover a molten solution capable of yielding aluminium under electrolyses?

c) What must be eliminated from the solution?

d) What groups can the processes of welding be divided into?

4. Disjunctive questions:

a) Upsetting involves a flow of the metal back upon itself, doesn't it?

b) Such inclusions can be avoided by proper manufacturing procedures, can't they?

c) Welding processes are classified according to the sources of heat and pressure used, aren't they?

d) Fusion welding is more effective with alternating current, isn't it?

We 1) (visited) the Marple Hotel in July 2002, when we 2) (decided) that we would not feature the hotel in our brochure. There 3) (were) a number of reasons for this: the rooms 4) (needed) upgrading, we 5) (felt) that the stan­dard of service 6) (was not) good enough, and the hotel 7) (did not seem) to be well managed.

However, a great deal 8) (has changed) since 2002, and the hotel is now under new management. They 9) (have redecorated) all the rooms and they 10) (have made) the restaurant much more comfortable and attractive.

They 11) (have also built) a new pool. They 12) (have started) work on a new extension which should be complete by April next year, and this will bring the number of available rooms to 200. The new manager 13) (has introduced) an incentive scheme for the staff, 14) ( increased) salaries, and 15) ( sent) a number of employees on training courses, and as a result the level of service 16) (has improved) a great deal.

The restaurant is gaining a good reputation. The new chef 17) (has been) at the hotel for three months, and will clearly maintain high standards of cuisine. He 18) (was trained) in Paris a few years ago, and then 19) (workedat the Tour d'Argent. Since his ar­rival, he 20) (has created) a new menu and 21) (hired) a new maitre d'hotel to train the waiters. We 22) (had) a meal at the restaurant last night and 23) (think) the standards were excellent.
