TOEFL iBT Practice (Grammar & Vocabulary) — All Questions

He has worked at this university ___ 2010. Which choice is correct?

• a.for
• b.from
• c.since✓
• d.during

'Since' is used with a specific starting point in time (2010) alongside the present perfect. 'For' would be used with a length of time, such as 'for ten years'.

We need ___ chairs than we currently have for the event. Which choice is correct?

• a.less
• b.lesser
• c.little
• d.fewer✓

'Chairs' is a countable noun, so 'fewer' is correct. 'Less' is used with uncountable nouns, such as 'less water'.

I look forward to ___ from you soon. Which choice is correct?

• a.hearing✓
• b.hear
• c.heard
• d.to hear

In 'look forward to', the word 'to' is a preposition, so it must be followed by a gerund: 'hearing'. This is a common usage trap.

Her research is closely related ___ climate science. Which preposition is correct?

• a.with
• b.to✓
• c.on
• d.at

The correct collocation is 'related to'. English speakers say something is 'related to' a topic, not 'related with' it.
