A2 Key for Schools (KET) Reading & Writing Part 5 Test – Tech Disconnects: Apologies & Polite Refusals 1

25 to

– Why it's right: We use "to" before a base verb (say) to explain the reason or purpose for doing an action.

– Why not 'for': We do not use "for" with a base verb. You could say "for saying", but we cannot write "for say".

26 on

– Why it's right: We use the preposition "on" when we talk about travelling on large public transport where you can stand up and walk around, like a bus, train, or plane.

– Why not 'in': We only use "in" for small vehicles where you must sit down immediately, like a car or a taxi.

27 so

– Why it's right: We use the linking word "so" to introduce the result of an action. Because John found his charger, the result is that he can reply.

– Why not 'because': "Because" introduces a reason. In this sentence, the reason comes first, and the gap introduces the result.

28 for

– Why it's right: When we express gratitude to someone, we always use the preposition "for" to complete the phrase "thank you for [doing something]".

– Why not 'of': We never say "thank you of". "Thank you for" is a fixed expression that goes together.

29 are

– Why it's right: We need the auxiliary verb "are" to match the plural pronoun "we" and complete the future plan structure "are going to".

– Why not 'do': We cannot write "do we going" because the verb "do" cannot be used together with an -ing word.

30 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 say "let I know" because "I" is a subject pronoun and is only used at the beginning of a clause, never directly after a 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 asking in this type of phrase.

26 but

– Why it's right: We use but to connect two opposite or contrasting ideas, like wanting to do something and not being able to do it.

– Why not 'because': Because gives a reason, but here Lily needs to show a contrast between wanting to play and not being able to join.

27 lot

– Why it's right: The fixed phrase a lot of is used to talk about a large amount of something, like homework.

– Why not 'many': We cannot say a many of; many is used with plural words and is not followed by of in this way.

28 the

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

– Why not 'a': We cannot use a because there is only one hardest project, not many.

29 it

– Why it's right: We use the pronoun it to replace a singular noun, so we do not have to repeat the word project or homework.

– Why not 'them': We use them for plural nouns, but project is just one thing.

30 on

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

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

25 because / as / since

– Why it's right: We use because to explain the reason for doing something. Mark is explaining the reason why he is writing the note.

– Why not 'but': The word but is used to show a difference or contrast, not to explain why something happens.

26 to

– Why it's right: We use to before a base verb to explain why we did an action. Mark used the computer to play a game.

– Why not 'for': We can use for with a noun, but before a base verb like play, we must always use to.

27 on / onto

– Why it's right: We use the preposition on to show that an object is touching a flat surface, like the ground or the floor.

– Why not 'in': We use in when something is inside a closed space, like a box, not for a flat surface like a floor.

28 is

– Why it's right: We need the present simple verb is because the subject of the sentence (one side) is singular. It describes a fact that is true right now.

– Why not 'are': Even though the word them is plural, the main subject is only one side, so we must use the singular verb is.

29 so

– Why it's right: We use so to link a reason with a result. Knowing his brother uses the headphones every day is the reason, and feeling terrible is the result.

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

30 a

– Why it's right: We use the indefinite article a when we talk about one single, countable thing for the first time. Mark means one new pair of headphones.

– Why not 'the': We use the for a specific item that the listener already knows about, but Mark has not chosen the exact headphones yet.
