Summary of Essential English Grammar: Verbs and Adverbs
Essential English Grammar: Verbs and Adverbs for Students
Introduction
The aim of this material is to help high school students understand and use vocabulary and expressions related to the calendar in Spanish. We'll explore how to express past dates, how to form the simple past tense of common verbs, and how to organize temporal information into clear sentences.
Definition: A calendar is a system for dividing time into units such as days, weeks, months, and years, and for naming specific dates.
1. Past Time Expressions (Dates and Periods)
To describe events that happened in the past, we use time expressions that pinpoint when the event occurred. Below are examples based on the provided content, converted into natural past expressions in English:
- Today, 11:00-21:00
- Example: Today I worked from 11:00 AM to 9:00 PM.
- Sunday, November 13, 2022
- Example: On Sunday, November 13, 2022, I went to the market.
- Yesterday
- Example: Yesterday I studied for the exam.
- Saturday, November 12, 2022 (day before the year)
- Example: On Saturday, November 12, 2022, we celebrated an event; it was the day before the start of the mentioned annual period.
- Last week, Monday 7 — Friday
- Example: Last week, from Monday the 7th to Friday the 11th, I attended in-person classes.
- November 11, 2022
- Example: On November 11, 2022, there was a school meeting.

- Monday, November 7, 2022

Tips for Using Time Expressions
- For exact dates: use the format "On [Month] [Day], [Year]", for example: "On November 13, 2022".
- For periods: use "from ... to ...", for example: "From October 17 to 21, 2022".
- For relative references: use "yesterday", "today", "last year", "last week".
Definition: Past time expressions are words or phrases that indicate when an event occurred in relation to the present moment.
2. Simple Past Tense Formation (Pretérito Indefinido) — Focusing on the 'You' Form
While English materials might focus on forming simple past verbs and identifying regular ones, this section adapts that concept to Spanish, explaining its equivalent: the pretérito indefinido.
Basic Rules in Spanish (Regular Verbs):
- Verbs ending in -ar: -é, -aste, -ó, -amos, -asteis, -aron
- Example: hablar (to speak) -> yo hablé (I spoke), tú hablaste (you spoke), él habló (he spoke)
- Verbs ending in -er: -í, -iste, -ió, -imos, -isteis, -ieron
- Example: comer (to eat) -> yo comí (I ate), tú comiste (you ate), ella comió (she ate)
- Verbs ending in -ir: -í, -iste, -ió, -imos, -isteis, -ieron
- Example: vivir (to live) -> yo viví (I lived), tú viviste (you lived), ellos vivieron (they lived)
Common Irregular Verbs (Examples): ser/ir (to be/to go) -> fui (I was/went), fuiste (you were/went), fue (he/she/it was/went); tener (to have) -> tuve (I had), tuviste (you had), tuvo (he/she/it had); hacer (to do/make) -> hice (I did/made), hiciste (you did/made), hizo (he/she/it did/made).
Practice Activity (Adapted)
Complete with the pretérito indefinido:
- (trabajar - to work) Yesterday I _______ from 11:00 to 21:00. -> Yesterday I trabajé (worked) from 11:00 to 21:00.
- (ir - to go) On Sunday, November 13, 2022, we _______ to the park. -> fuimos (went).
- (entregar - to turn in) On Monday, November 7, 2022, she _______ the homework. -> entregó (turned in).
Definition: The pretérito indefinido is a verb tense that expresses actions completed in the past.
