Example: It has been suggested (1) that lipid peroxides formed in the arterial wall are active in atherogenesis. The suggestion has been widely accepted as reasonable. This indicates that the 'suggestion' and its 'acceptance' took place in the past but are still
having an effect now at the time of writing.
2.2.4 The Past Perfect If you want to talk about a past event or situation that occurred before a particular time
in the past, you use the past perfect.
E xample: In the second trial it was noticed that a culture plate had become contaminated by a mould. This indicates the "noticing" took place in the past and the culture plate was
contaminated before the "noticing" took place.
