Subject-verb agreement (2)

Activity 1 Look at the sentences from the reading passage and answer the questions.

a …50 per cent of my time was spent researching new restaurants.

b Every recommendation she gives me is great…

c … almost 50 per cent of US jobs are at risk from automation in the next 20 years.

d …none of us is prepared for the challenges of AI.

Activity 1 Look at the sentences from the reading passage and answer the questions.

Because in sentence (a), the part “50 per cent” is followed by the uncountable noun “time”, while in sentence (c), the part “50 per cent” is followed by the countable noun “job” in its plural form.

In sentence (b), the part “Every recommendation” is the subject. In sentence (d), the part “none of us” is the subject. Both are singular.

1 Why is 50 per cent singular in sentence (a) but plural in sentence (c)?

2 What are the subjects in sentences (b) and (d)?

Are they singular or plural?

Activity 1

Now look for more sentences following this rule in the reading passage, and summarise the use of subject-verb agreement in your own words.

Activity 2 Complete the passage by choosing the singular or plural form.
