Presentation

During his talk, the Research Engineer expressed the concepts of CAUSE and EFFECT in three different ways:

a. When clause

e.g. When the piston is cold, the coil contracts.

b. Verbs linking the cause to the effect

e.g. Heat causes it to expand. (cause something to happen)

This makes the fan close. (make something happen)

Cold weather leads to expansion. (lead to

results in (result in something)

brings about (bring about

с. Adverbs linking the cause to the effect

e.g. The spring contracts and so allows the fan to operate.

therefore

consequently

thus

as a result

A. Use the above three ways of expressing cause and effect, and the table from Section 1, to finish these sentences.

the SMA actuator ________ the valve and______ the water

2. ___________ it______________, the spring ________.This________ the

fan ________ ________ and ________ the car_________________

3. In warm weather, the spring ________ and ________ the fan ________. This ________ the car _________________________

B. Use the diagram of a process cycle to complete the description:

__________the temperature__________,___________________ and __________

_____________________. This _________the heater to be switched off and

________________________________. In time, the metal contracts and

__________broken. The broken contact _________the heater ________________
