Answer (1)
For this exercise, you need to put the verbs in parentheses into the correct past tense form. The sentences seem to be focusing on using the past simple and past perfect tenses.
In sentence 5, the correct past form is: 'They had not studied English before last year.'
The past perfect tense 'had not studied' is used here. This tense indicates that the action of not studying English happened before another action in the past (last year).
In sentence 6, the correct past form is: 'She had lived in Leeds before she moved to London.'
In this sentence, 'had lived' is in the past perfect tense to show that living in Leeds happened before moving to London.
In sentence 7, the correct past form is: 'The baby had fallen asleep before eight o'clock.'
Here, 'had fallen asleep' is past perfect. It indicates that the baby falling asleep happened prior to eight o'clock.
In sentence 8, the correct past form is: 'I could not think of that question before.'
'Could not think' is in the past tense. This indicates a simple past action that did not occur before another point in the past.
In sentence 9, the correct past form is: 'Sue got wet because she had not brought an umbrella.'
'Had not brought' is past perfect, showing that the action of not bringing an umbrella happened before she got wet. This explains the consequence of her not bringing an umbrella.
These exercises are designed to help you understand how time relationships between past events can be expressed using different past tenses.
