A2 Key for Schools (KET) Reading & Writing Part 5 Test – Tech Disconnects: Apologies & Polite Refusals 3

25 for

– Why it's right: We use the preposition "for" after "sorry" to explain the reason for our apology, especially when it is followed by an -ing verb (leaving).

– Why not 'about': While you can say "sorry about yesterday", you must use "for" when followed directly by an action ending in -ing.

26 but

– Why it's right: We use the conjunction "but" to connect two opposite or contrasting ideas (having fun vs. the computer turning off).

– Why not 'because': "Because" introduces a reason, but the computer turning off is certainly not the reason they were having a great time.

27 had

– Why it's right: The sentence is talking about yesterday ("wanted", "said"), so we must use the past tense of "have to", which is "had to", to describe a past rule.

– Why not 'have': "Have" is the present tense form, but this event already happened in the past.

28 without

– Why it's right: We use "without" to mean 'not together with someone'. Here, it means Alex had to finish the game alone because Sam was gone.

– Why not 'with': "With" means together, but we already know from the message that Sam left the game early.

29 me

– Why it's right: We need the object pronoun "me" because it receives the action of the verb "let". "Let me know" is a very common phrase to ask for a reply.

– Why not 'I': We cannot write "let I know" because "I" is a subject pronoun and is only used at the beginning of a clause.

30 can

– Why it's right: We use the modal verb "can" before a base verb (play) to talk about a possibility or an offer for the future.

– Why not 'are': A common mistake is writing "we are play", but the verb "to be" (are) can never be followed directly by a base verb.

25 for

– Why it's right: We always use the preposition for after thank you when we explain the reason we are happy (thank you for doing something).

– Why not 'to': We do not use to before an -ing verb like inviting in this type of phrase.

26 but

– Why it's right: We use but to connect two opposite or contrasting ideas, like wanting to spend time together and not being able to watch the film.

– Why not 'because': Because gives a reason, but here Eva needs a word to show the contrast between her two feelings.

27 the

– Why it's right: We always use the definite article the before superlative adjectives like scariest, biggest, or best.

– Why not 'a': We cannot use a because there is only one scariest movie of the year, not many.

28 so

– Why it's right: We use so to talk about the result of a situation (because she gets frightened, the result is that she prefers comedies).

– Why not 'because': We use because to explain the reason why something happens, but here the second part of the sentence is the result.

29 on

– Why it's right: We always use the preposition on before days of the week, like on Saturday or on Friday.

– Why not 'at': We use at for the weekend or for exact clock times, but never for specific days of the week.

30 to

– Why it's right: We always use to after the verb want when it is followed by another action (want to do something).

– Why not 'for': Students often confuse to and for, but we never say want for come before a base verb in English.

25 to

– Why it's right: We use the preposition to to show movement in the direction of a place (the park).

– Why not 'at': We use at when we are already in a place, but we use to with the verb take to show the destination.

26 so

– Why it's right: We use so to link a reason with a result. The phone having a low battery is the reason, and needing to use the charger is the result.

– Why not 'because': The word because comes before the reason, but this gap needs a word that introduces the result.

27 of

– Why it's right: The preposition of goes with out to make the phrase out of. This describes something leaving the inside of a container, like a bag.

– Why not 'from': We can say something fell from a table, but when it leaves the inside of a closed space, we always use the phrase out of.

28 a

– Why it's right: We use the indefinite article a when we talk about a single, countable thing for the first time.

– Why not 'the': We do not use the here because Tom has not chosen the exact new charger yet; he just means one replacement charger in general.

29 me

– Why it's right: We need an object pronoun here. Tom is asking Sam to do an action (send a link) that is directed at him, so we use me.

– Why not 'I': We cannot say send I a link because I is a subject pronoun, and this position in the sentence requires an object pronoun.

30 for

– Why it's right: The verb pay is almost always followed by the preposition for when we talk about the specific item we are buying.

– Why not 'to': We can say pay the money to you, but when we name the item we are buying, the correct phrase is pay for.
