A2 Key for Schools (KET) Reading & Writing Part 5 Test – Tech Recommendations: Suggesting Apps, Games & Content 3

25 a

– Why it's right: We use "a" before a singular, countable noun phrase (great new mobile game) when we tell someone about it for the very first time.

– Why not 'the': We cannot use "the" here because Alex does not know which specific game Jack is talking about yet.

26 on

– Why it's right: We always use the preposition "on" when we talk about putting or using programs on digital devices with screens (e.g., on a phone, on a computer, on TV).

– Why not 'in': We never say an app is "in" a phone because we interact with the screen on the surface, not the physical pieces inside the machine.

27 the

– Why it's right: We always use the definite article "the" before superlative adjectives like "best", "biggest", or "easiest" because there is only one top thing.

– Why not 'a': We cannot say "a best" because "a" means one of many, but superlative words mean something is at the absolute top.

28 and

– Why it's right: We use the conjunction "and" to connect two similar positive actions or ideas (building a garden + planting trees).

– Why not 'because': "Because" introduces a reason, but planting trees is not the reason you build a garden; it is simply another fun activity you can do.

29 are

– Why it's right: We need the verb "are" to match the plural word "colours" and complete the phrase "there are" to describe things that exist in the game.

– Why not 'is': A common mistake is writing "there is many", but "is" can only be used to introduce one singular item.

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 everyday phrase used 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, not right after an action verb.

25 of

– Why it's right: We use of to connect two nouns and show that something belongs to a group or relates to them (the lives of teenagers).

– Why not 'for': We don't say lives for teenagers in this kind of description; of is the correct preposition here.

26 am

– Why it's right: We use am with the pronoun I and an -ing verb (walking) to form the present continuous tense.

– Why not 'was': The word usually means this is a habit that happens in the present, so we cannot use a past tense verb like was.

27 the

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

– Why not 'a': We cannot use a because there is only one best show in this context, not many.

28 going

– Why it's right: We use going after the verb are and before to when we ask about future plans (are going to be).

– Why not 'go': We cannot use the base verb go after are in this future tense structure.

29 on

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

– Why not 'in': We use in for the afternoon by itself, but when we mention a specific day, we must always use on.

30 to

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

– 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 to before a base verb to explain why we do an action. David is writing this message to tell his friend something.

– Why not 'for': We can use for with a noun (like a message for you), but before a base verb like tell, we must always use to.

26 at

– Why it's right: In English, we always use the preposition at with the word night to talk about this time of day.

– Why not 'in': We use in for other parts of the day (like in the morning or in the evening), but we never say in night.

27 on

– Why it's right: We use the preposition on when we talk about things displayed on digital screens, making the phrase on your phone.

– Why not 'in': You can put your phone in your pocket, but the correct preposition for looking at screens and devices is always on.

28 for

– Why it's right: We use the preposition for after adjectives like good or better to show who or what receives a positive, healthy effect.

– Why not 'to': We can say something happens to your eyes, but to describe something as being healthy or helpful, the correct phrase is better for.

29 than

– Why it's right: We use than after a comparative adjective like better to compare two different situations or times (sleeping now and sleeping before).

– Why not 'that': That looks and sounds very similar to than, but it is a pronoun, not a word used for comparing things.

30 in

– Why it's right: In English, we always use the preposition in when talking about general parts of the day, making the phrase in the morning.

– Why not 'at': We use at for specific clock times (like at 9 o'clock) or for at night, but we never use it with the morning.
