The Big 3 for Vietnamese Speakers: Articles, Plurals, and Verb Tense: correct answers
Jump to answers ↓Articles, Plurals, and Basic Verb Tenses
Mastering the "big three"—articles, plurals, and verb tenses—is essential for clear communication. A tiny change can make a massive difference! For example, saying "I bought an apple" introduces a new item, while "I bought the apple" refers to a specific one you already mentioned. Similarly, remembering the -s in "three cats" or the -ed in "stepped" tells your listener exactly how many things there are and when an action happened.
Inside, you will tackle these foundational rules. The exercises cover definite and indefinite article progression (like a dog becoming the dog), regular plural noun forms for everyday items, and choosing between present simple and simple past verb tenses.
You will apply these rules to fun scenarios—like helping a detective verify an alibi, a wizard brew a potion, and an alien introduce himself. You'll work through 14 questions featuring a mix of single-choice, multi-choice, drop-down, and drag-and-drop formats.

Correct answers
Question 1
Complete the detective's case notes by choosing the correct verb form for each blank.
Every morning, the detective drinks a large cup of coffee. However, yesterday she spilled it all over her desk when a suspect knocked on the door.
Every morning, the detective drinks a large cup of coffee. However, yesterday she spilled it all over her desk when a suspect knocked on the door.
drinks: For habits and routines ("Every morning") with a "he/she/it" subject, we must add an -s to the verb.
spilled & knocked: Because these actions happened "yesterday," we must use the past tense by adding -ed to regular verbs.
Tip for Vietnamese speakers: Time words like "yesterday" or "every morning" are great clues, but remember that English verbs also have to change their shape (adding -s or -ed) to match the time!
Question 2
The correct answers are The chef makes an amazing mushroom soup. and I always enjoy the atmosphere at this lovely restaurant.
We use an before words that start with a vowel sound (like amazing).
We use the when talking about a specific, unique thing in a certain context (like the atmosphere of a specific restaurant).
Many learners forget to include articles entirely, but in English, singular countable nouns and specific uncountable nouns usually need a little helper word in front of them!
Question 3
I just saw a cute dog outside the café. The dog was wearing a tiny yellow sweater and eating an apple!
We use a or an when mentioning a singular, countable noun for the first time ("a dog", "an apple"). Once the noun is known to the listener or reader, we use the definite article the ("The dog").
Question 4
I usually wake up on time, but today my alarm clock didn't go off. Then, on my way here, a stray cat stole my homework!
English verbs change their form to show time. Use the present simple ("wake") for daily habits and routines. Use the past simple ("didn't", "stole") for finished events that happened in the past, even if it was just this morning!
Question 5
Help the amateur baker prepare for the grocery store by choosing the correct noun form for each blank.
My famous cake recipe requires three apples, but I only have one banana in my kitchen. I also need to buy two large eggs from the market.
My famous cake recipe requires three apples, but I only have one banana in my kitchen. I also need to buy two large eggs from the market.
apples & eggs: In English, when you have more than one of a countable noun, you must add an -s or -es to the end of the word.
banana: Because there is only "one," the noun remains in its singular form without an -s.
Tip for Vietnamese speakers: Even though numbers like "three" or "two" already tell us there is more than one, English still requires that extra "s" at the end of the noun!
Question 6
The correct answers are I watched a movie at home all evening. and My dog slept on the couch next to me.
When an action is finished in the past, English verbs change their form! Regular verbs take -ed (watch becomes watched). Irregular verbs change completely (sleep becomes slept, not sleeped).
Leaving the verb in its base form (watch) when talking about yesterday is a very common trap!
Question 7
I packed three shirts and two pairs of shoes, but I completely forgot to bring a toothbrush!
Unlike Vietnamese, English requires an -s (or -es) at the end of countable nouns when there is more than one ("three shirts", "two shoes"). For a single item, always use the base singular form ("a toothbrush").
Question 8
The correct answers are Three heavy boxes of books and Several comfortable pillows.
In English, you must add -s or -es to show that there is more than one countable item (boxes, books, pillows).
However, uncountable nouns like furniture, information, or water do not take an -s. "Two new wooden furnitures" is incorrect; you would say "Two pieces of wooden furniture."
Question 9
Help the wizard complete his potion recipe.
To make the invisibility potion, you need three magical ___.
The correct answer is feathers.
In English, when we have more than one countable noun (like "three"), we must add an "-s" or "-es" to make it plural! Because Vietnamese doesn't change the noun form based on quantity, this is a super common trap for learners. Always remember your plural "s"!
Question 10
Help the delighted tourist complete his travel blog post by choosing the correct article for each blank.
I saw a cute stray cat outside my hotel. I gave some tuna to the cat, and now it thinks I am an absolute hero.
I saw a cute stray cat outside my hotel. I gave some tuna to the cat, and now it thinks I am an absolute hero.
a: We use "a" when introducing a singular countable noun for the first time (a cute stray cat).
the: We use "the" when referring to a specific noun that has already been mentioned (the cat).
an: We use "an" before words that start with a vowel sound (an absolute hero).
Tip for Vietnamese speakers: Unlike in Vietnamese, singular nouns in English almost always need a little "hat" (an article) before them!
Question 11
Complete the time traveler's awkward apology.
I'm so sorry! Yesterday, I accidentally ___ on a dinosaur and changed history!
The correct answer is stepped.
The word "Yesterday" is a huge clue that this happened in the past. Unlike in Vietnamese, where tense is shown by adding words like "đã" while keeping the verb the same, English verbs must physically change their shape to show the past tense. For regular verbs like "step," we double the final consonant and add "-ed."
Question 12
Finish the script for the dramatic nature documentary.
The fierce house cat wakes up, yawns, and immediately ___ back to sleep.
The correct answer is goes.
For a singular subject ("the cat" = "it") in the present tense, we must add "-s" or "-es" to the verb. It's easy to forget this "third-person singular S" because Vietnamese verbs never change form regardless of who is doing the action, but it's an essential habit to build in English!
