In A2 Key Reading and Writing Part 5, a small missing word can carry a large amount of meaning. An article introduces a noun, an auxiliary builds a tense and a preposition connects an activity to a time or place. Knowing these jobs helps you make a reasoned choice instead of guessing from a list of familiar words.
The task has six gaps in an email, sometimes including a reply. You write one word in each gap. There are no options to compare. Read the whole message before filling anything in, because a later sentence may explain a pronoun, time reference or relationship.
The title’s “most gaps” refers to useful categories for preparation, not a statistical promise about future papers. No short word list can guarantee the answer. This guide uses original teaching emails and explains how grammar and meaning work together.
Think about a job before a word
Suppose you see “Would you like ___ come with us?” The pattern “would like to do something” suggests “to”. You have identified a structure rather than remembered a topic word.
Now compare “We travelled ___ bus”. The missing word belongs to the transport expression “by bus”. A different sentence, “We waited ___ the bus”, needs “for”. The noun alone does not decide the answer; the whole phrase does.
Ask three questions: what kind of word could fit, what structure surrounds it and what meaning does the full sentence need? Write your first reasonable answer lightly, then check it after reading the complete email again.
The main categories worth practising
Pronouns and possessives
Subject pronouns do actions: “She called”. Object pronouns receive them: “I called her”. Possessives connect people and things: “her bag”, “our lesson” and “your ticket”. Look at the word after the gap and decide whether it is a noun or a verb.
Reference matters too. In an email to a friend, “you” may be the natural person to meet or help. But do not assume every missing pronoun refers to the recipient. Read back to see which person or thing is being discussed.
Articles and determiners
“A”, “an” and “the” help a reader identify a noun. Use “a” or “an” to introduce one countable thing, with the choice based on sound. Use “the” when the context identifies the thing. Other determiners include “this”, “that”, “some”, “any”, “much” and “many”.
Countability can narrow the choice. “Many books” and “much time” follow different patterns. Learn the noun and expression together. A gap before a noun may also need a possessive rather than an article, so meaning still matters.
Prepositions
Practise common time and place phrases: “at six”, “on Monday”, “in July”, “next to”, “in front of” and “at the station”. Also collect dependent patterns such as “interested in”, “listen to” and “thank you for”.
Avoid translating a preposition directly from your first language. Learn an ordinary sentence you might use. For example, “I’m interested in music” gives you both the adjective and its partner.
Auxiliary and modal verbs
Small verbs help build questions, negatives and tenses. Compare “Do you like it?”, “Did you see it?” and “Have you finished?” The main verb form is a clue: “finished” after “have” has a different role from “finish” after “did”.
Forms of “be” are especially useful: “I am waiting”, “she is ready” and “there are two seats”. A plural subject can decide between “is” and “are”. Read the whole subject rather than the nearest noun alone.
Conjunctions and other connecting words
“And” adds, “but” contrasts, “because” gives a reason and “so” introduces a result. Do not choose a connector only because the grammar allows it. Check the relationship: “It was raining, so we stayed inside” expresses a result.
Other patterns include “as… as”, “more… than”, “too… to” and question expressions such as “how much”. Treat both halves as a unit. Our Vocabulary & Grammar guide has more examples of linking words in use.
A short checking sequence
| Step | What to ask | What it prevents |
|---|---|---|
| Read | Who is writing, and why? | Misunderstanding the situation |
| Predict | What job does the missing word do? | Random vocabulary guesses |
| Check left and right | Which pattern surrounds the gap? | A word that fits only one side |
| Reread | Does the complete message make sense? | Broken reference or logic |
| Verify | Is it exactly one word? | An answer that ignores the instruction |
Do not spend the whole practice session on one gap. Make a decision, mark uncertainty and move on. After checking the answers, return to the difficult pattern and write a new example. That turns uncertainty into a useful learning record.
Original practice email 1: a museum visit
Read this email and write one word in each gap. Try all six before opening the explanation.
Hi Ben,
Thanks (1) _____ inviting me to the museum on Saturday. I would love (2) _____ come. The special tour starts (3) _____ ten, so we should leave early. I will bring (4) _____ umbrella because the weather may be wet. I can meet (5) _____ outside your house if that is easier. Please tell me (6) _____ much the tickets cost. My sister may come too, but she will decide tomorrow.
See you soon, Eva
Answers and explanations for email 1
- for — use “thanks for” followed by a noun or an -ing form. Here “inviting” names the action being appreciated.
- to — the pattern is “would love to come”. A modal-like meaning does not remove the “to” in this expression.
- at — a specific clock time takes “at”: “at ten”.
- an — an umbrella is one countable item being introduced, and “umbrella” starts with a vowel sound.
- you — Eva is addressing Ben and offering to meet him outside his house. The object form needed here is “you”.
- how — “how much” asks about the price. Read the phrase across the gap rather than choosing a preposition.
For review, change the time, object and price question. Write a new sentence with “thanks for” and another with “would love to”.
Original practice email 2: a new neighbourhood
Again, use one word per gap. The topic is familiar, but each answer still needs a grammatical reason.
Hi Sara,
I haven’t seen you (1) _____ last month. How are you? Our family has (2) _____ new flat near the river. The bus journey to college is slower (3) _____ the train journey, but the stop is close to our door. There (4) _____ two small shops downstairs, which is useful. I (5) _____ going to buy a bicycle next weekend, so I can explore the area. Would you like to visit? Please (6) _____ me know which day is best for you.
Love, Tia
Answers and explanations for email 2
- since — “last month” identifies the starting point of the period without seeing Sara. “For” would introduce a duration, such as “for three weeks”.
- a — the flat is introduced as one new countable home. “New” begins with a consonant sound.
- than — “slower than” is a comparative pattern comparing the two journeys.
- are — “two small shops” is plural, so the structure is “there are”.
- am — with the subject “I”, the future-plan pattern is “I am going to buy”.
- let — “let me know” is a fixed, useful way to ask someone to provide information.
Compare “since last month” with “for a month”. Then use “let me know” in a short invitation of your own.
How to learn from your answers
Record the full corrected phrase rather than only the missing word. A notebook entry that says “for” is hard to use later. An entry that says “Thanks for helping me” reminds you of the structure and its meaning.
If you chose a different word, read your completed sentence aloud. Does it create a grammatical phrase? Does it make sense in the whole email? If more than one answer seems plausible in a teaching exercise, discuss the full sentence rather than assuming that a familiar answer is always right.
Notice whether your errors cluster. Several problems with articles suggest a different revision focus from several problems with verb forms. Use the irregular verbs drill for recall where useful, but remember that choosing an auxiliary requires understanding the sentence as well as knowing a form.
Connect reading with your own writing
The same small words make short emails readable. After completing these sets, write an invitation using “Would you like to…?”, a time phrase and a request. Then check whether each word performs a clear job.
Our Part 6 email workshop shows how to cover three prompts in a short message. You can also try the mini practice sets for another A2 email and a B1 open-cloze text. Work slowly enough to understand the pattern before trying to get faster.
Key takeaways
- Read the whole email before filling the six one-word gaps.
- Identify the missing word’s job, then check the complete phrase.
- Learn articles, pronouns, prepositions, auxiliaries and connectors in sentences.
- Review a corrected pattern and use it in your own writing.
