Core Principles

Grammar Focus	Structure & Rule	Key Examples
1. Careful English Relative Clauses	Preposition + which / whom In formal or academic contexts, the preposition precedes the relative pronoun. That is never used directly after a preposition.	"This is the street in which I live." Sustainable infrastructure creates areas in which residents thrive.
2. Everyday English Relative Clauses	Preposition at the end In conversational English, the preposition moves to the end of the relative clause. Relative pronouns (which, that, who) may even be omitted.	"This is the street which I live in." This is the suburb that most workers commute to.
3. Present Perfect Passive	has / have been + Past Participle Describes a completed action whose result is relevant now, when the agent is unknown, obvious, or less important than the recipient.	"A new park has been built." Urban highways have been redesigned for pedestrian safety.
4. Present Perfect Passive with Time Markers	since + point in time / for + duration Highlights states or ongoing consequences starting in the past and continuing into the present moment.	"The old bridge has been closed since March." Traffic congestion has been monitored for six months.

Key Takeaway

Remember the register distinction: Use preposition + which (e.g., "This is the street in which I live") in academic and official reporting on urban infrastructure. Keep dangling prepositions ("This is the street which I live in") for casual speech. When discussing actions with current relevance, use has/have been + V3, anchoring the timeline with since for specific dates and for for measurable durations.
