Some of the exercises are in the form of a conversation between two people. Quotation marks are not used here but the
second remark is usually printed directly below the first.
When both remarks are very short they are sometimes printed on the same line with a wide space between them.
This is a reference grammar for upper forms in schools and for adult learners at an intermediate stage, though it will also prove useful for the more advanced.
