Used to describe an initial impression of something, before looking at it more closely.
“At first glance, this looks like a typical family outing to the park.”
“At first glance, the street appears calm, but there's a lot happening in the background.”
Use this phrase to open your description in Task 3 with a general impression before diving into specific details — it creates a natural structure of moving from the 'big picture' to closer observations, which examiners like to see.
Synonyms: initially, at a first look, on first sight
