A2 Key for Schools (KET) Reading & Writing Part 5 Test – Future Streams: Planning Tech Purchases & Digital Catch-ups 5

25 a

– Why it's right: We use the word "a" before a singular, countable noun phrase (new website) when we mention it to someone for the first time.

– Why not 'the': We cannot use "the" here because the boys are just starting the project, so a specific website does not exist yet.

26 with

– Why it's right: We use the preposition "with" to show that two or more people are doing an activity together as a team.

– Why not 'for': If you write "do it for me", it means Alex must do all the hard work as a favour, but Ryan wants them to build it together.

27 on

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

– Why not 'in': We never say "in a computer" because you interact with the screen on the surface, not the physical parts inside the machine.

28 but

– Why it's right: We use the conjunction "but" to connect two contrasting ideas. They have the photos (a positive step), but they still lack the text (a missing step).

– Why not 'because': "Because" introduces a reason. Needing to write text is not the reason they found the photos.

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 'will': While "will" also talks about the future, we cannot write "We will going" because "will" is never followed directly by 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 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 a verb.

25 of

– Why it's right: We use of in the fixed phrase a lot of to talk about a large amount of something.

– Why not 'for': We cannot say a lot for; the correct preposition to complete this quantity phrase is always of.

26 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 organize before a base verb in English.

27 for

– Why it's right: We use for to explain the purpose of an object or what it will hold (a folder for the music).

– Why not 'to': We do not use to before a noun phrase like all the rock music to show purpose; to is used before a verb.

28 than

– Why it's right: We use than when we are comparing two people or things (better than I am).

– Why not 'then': Then is used to talk about time (meaning "next" or "at that time"), but it is never used for comparing things.

29 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.

30 me

– Why it's right: Let me know is a very common fixed phrase in English which simply means "tell me".

– Why not 'I': After the verb let, we must always use an object pronoun like me, never a subject pronoun like I.

25 because / as / since

– Why it's right: We use because to give a reason for an action. Max is explaining the reason why he is writing the message.

– Why not 'so': We use so to talk about a result, while this sentence needs a linking word that explains why something is happening.

26 am / 'm

– Why it's right: We use the auxiliary verb am with the pronoun I and the phrase going to to talk about our future plans.

– Why not 'will': We cannot say I will going because the modal verb will must always be followed by a base verb, not an -ing verb.

27 on

– Why it's right: In English, we always use the preposition on when we talk about reading or finding information on a website or on the internet.

– Why not 'in': We can look in a book, but the correct preposition for screens and the internet is always on.

28 than

– Why it's right: We use than after a comparative adjective like cheaper to compare two different places (the internet and the shops).

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

29 at

– Why it's right: We always use the preposition at after the adjective good when we talk about a person being able to do an activity well.

– Why not 'in': Students often guess in, but in English, the correct collocation is always good at an activity or subject.

30 it

– Why it's right: The pronoun it is used to replace a singular thing that has already been mentioned in the text (the new memory part).

– Why not 'them': You would use them to replace plural words, but Max only bought one single computer part.
