Preposition Selection for Time, Place, Movement, and Dependent Preposition Phrases

Systemic Guidelines for Prepositions of Time

Prepositions of time specify when an action occurs relative to points, dates, and durations on a timeline. Non-native English speakers frequently struggle with temporal prepositions because direct literal translation from native languages often yields ungrammatical English structures. To select the correct preposition of time on the ACCUPLACER ESL test, apply the Specificity Pyramid of Time.

The Specificity Pyramid: At, On, and In

Useful Temporal Distinctions

Beyond at, on, and in, these contrasts build control of the prepositional phrases named in College Board's proficiency statements:

1. For vs. Since

• For + Duration of Time: Measures the total length or span of time (for three hours, for five years, for several semesters).
  • Example: "Professor Miller has taught linguistics at the university for ten years."
• Since + Starting Point in Time: Pinpoints the precise starting moment of an action that continues into the present (since 2018, since last Monday, since the semester began).
  • Example: "Professor Miller has taught linguistics at the university since 2016."

2. By vs. Until

• By + Specific Time (Deadline): Indicates that an action must be completed on or before a specific cutoff time. The focus is completion on or before the limit, not continuous duration up to it.
  • Example: "All undergraduate applicants must submit their final transcripts by July 1." (Submission happens once prior to July 1).
• Until / Till + Specific Time (Continuous Duration): Indicates that an ongoing action or state continues continuously up to a specific end point, and then stops.
  • Example: "The campus library will remain open until midnight during final exam week." (The library stays continuously open through the night up to 12:00 AM).

Spatial Relationships: Prepositions of Place, Location, and Movement

Prepositions of place categorize spatial boundaries, surfaces, and locations. Like prepositions of time, place prepositions follow a structured spatial pyramid based on physical dimensions.

Spatial Hierarchy of Place: At, On, and In

1. AT (One-Dimensional / Specific Point): Used for specific addresses, exact locations, target locations, or functional public points.
   • Street Addresses: "The administrative building is located at 450 College Avenue."
   • Functional Points: "Wait for the campus shuttle at the bus stop." / "The student is standing at the front desk."
2. ON (Two-Dimensional / Surfaces & Lines): Used for physical surfaces, floors of buildings, streets/avenues without building numbers, and public transportation vehicles where a person can stand or walk.
   • Surfaces: "Place the reference dictionary on the table."
   • Streets / Floors: "The registrar's office is on Fifth Avenue on the third floor."
   • Transit: "She reviewed her lecture notes while riding on the train."
3. IN (Three-Dimensional / Enclosed Spaces & Geographic Boundaries): Used for physical enclosures, buildings, rooms, cities, states, countries, and large geographical regions.
   • Enclosures / Rooms: "The computer science laboratory is in Building B in Room 204."
   • Geographic Areas: "Many international students live in Boston in Massachusetts."

Spatial Proximity and Comparison: Between vs. Among

• Between: Used for distinct relationships, whether two or more entities are involved.
  • Example: "The conflict between the student council president and the treasurer was resolved quickly."
• Among: Used for membership, distribution, or relationships within a collective group.
  • Example: "The scholarship committee distributed the funds among the eligible applicants."

Dynamic Prepositions of Direction and Movement

While prepositions of place represent static locations, prepositions of movement convey direction, path, or transition across boundaries:

• Into vs. In: In describes a static location inside, whereas into describes movement from the outside to the inside of a 3D space.
  • Static: "The students are sitting in the auditorium."
  • Dynamic: "The students walked into the auditorium."
• Onto vs. On: On describes a static position on a surface, whereas onto describes movement toward and onto a surface.
  • Static: "The microscope is resting on the counter."
  • Dynamic: "The lab assistant lifted the heavy equipment onto the counter."
• To vs. Toward / Towards: To presents a place as the endpoint or destination, whereas toward describes direction without asserting that endpoint.
  • Destination: "She walked to the library." (The library is presented as the destination).
  • Direction: "She walked toward the library." (She moved in that physical direction).

Dependent Preposition Phrases in Academic English

In standard written English, certain adjectives, verbs, and nouns require specific, fixed prepositions to link them to their grammatical objects. These structures are known as dependent prepositions. These patterns can appear in fill-in-the-blank items as part of sentence structure and idiomatic usage.

1. High-Frequency Adjective + Preposition Combinations

• Accustomed to / Used to: "International students quickly become accustomed to the college academic calendar."
• Aware of / Conscious of: "Candidates must be fully aware of all test center regulations."
• Capable of (+ Gerund): "The new supercomputer is capable of processing billions of calculations per second." (Note: Avoid capable to process).
• Different from: "Academic writing conventions in English are different from those in many other languages." (Note: Formal written English prefers different from over different than).
• Eligible for: "Students maintaining a 3.5 GPA are eligible for academic honors."
• Interested in (+ Gerund): "She is deeply interested in pursuing a degree in environmental engineering."
• Proficient in: "Applicants must prove that they are proficient in written English."
• Responsible for: "The lab manager is responsible for maintaining safety protocols."
• Similar to: "The format of the diagnostic exam is similar to the official test."

2. High-Frequency Verb + Preposition Combinations

• Apologize to (person) for (action): "The student apologized to the instructor for missing the deadline."
• Approve of: "The academic dean did not approve of the proposed schedule change."
• Comply with: "All laboratory experiments must comply with federal safety guidelines."
• Concentrate on / Focus on: "During the exam, candidates should concentrate on reading each question carefully."
• Consist of: "The placement examination consists of twenty multiple-choice questions."
• Depend on / Rely on: "Course placement depends on the student's overall performance."
• Insist on (+ Gerund): "The professor insisted on reviewing the original sources."
• Participate in: "Active engagement requires every student to participate in class discussions."
• Succeed in (+ Gerund): "With diligent practice, she succeeded in passing all placement modules."

3. High-Frequency Noun + Preposition Combinations

• Advantage of / Disadvantage of: "One major advantage of small class sizes is personalized instruction."
• Influence on / Impact on: "Technological advances have had a profound impact on higher education."
• Reason for: "The primary reason for the schedule adjustment was inclement weather."
• Solution to: "Researchers are striving to find an innovative solution to renewable energy storage."

4. Phrasal Verbs and Idiomatic Verb-Particle Combinations

College Board's upper proficiency statement includes less common idioms. Learn the whole unit and check whether an object may separate the verb from its particle:

• get over = recover from or overcome: "She got over the setback"; "She got over it."
• look into = investigate: "The committee will look into the complaint."
• put off = postpone: "They put off the meeting" or "They put it off." With a pronoun object, put it off is standard; put off it is not.
• carry out = perform: "The team carried out the experiment."

Do not infer a phrasal verb's meaning from the particle alone. Use sentence context, and keep a pronoun object in the required position for separable combinations.
