What figure of speech is used in the second and third lines?

Reading Comprehension:Read the quoted parts carefully and answer the questions in English．Write your answers in the corresponding space．Let us go then, you and I,
When the evening is spread out against the sky
Like a patient etherized upon a table;
Let us go, through certain half -deserted streets,
The muttering retreats
Of restless nights in one-night cheap hotels
And sawdust restaurants with oyster shells:
Streets that follow like a tedious argument
Of insidious intent
To lead you to an overwhelming question.…
Oh, do not ask, “What is it?”
Let us go and make our visit.
