Language study Comparison and contrast, 2.

In this unit we will examine some other ways to describe differences: to make contrasts.

On the tape the expert contrasted:

1 LPs and CDs

2 analogue and digital recording

3 CDs and newer systems

Here are some of the things he said:

They (CDs) use laser light rather than a needle.

LPs are analogue recordings while CDs are digital.

It (an analogue signal) can have any value ... but in digital the signal is either on

or off.

You can process a digital signal with greater accuracy than a constantly varying signal.

Here are some other expressions used to make contrasts:

differ from is/are different from in contrast to whereas unlike

Task 3 Look back at the table of differences in Task 2. Contrast LPs and CDs for each point in the table. Use the expressions from the examples listed above. For example:

Unlike LPs, CDs use a digital recording system.
