A2 Key for Schools (KET) Reading & Writing Part 5 Test – Future Streams: Planning Tech Purchases & Digital Catch-ups 6

25 about

– Why it's right: We use the preposition about after the verb talk to introduce the specific subject or topic of the conversation.

– Why not 'of': We often say think of something, but we must always say talk about a topic.

26 the

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

– Why not 'a': We never use a with superlative words because there is only one 'best' story, not many.

27 Do

– Why it's right: We use Do at the beginning of a present simple question with the pronoun you and a main base verb like want.

– Why not 'Are': We use Are with adjectives or verbs ending in -ing, but never with a base action verb like want.

28 because

– Why it's right: We use because to give the reason for doing something. The clear sound is the reason they should use that specific microphone.

– Why not 'so': We use so to talk about a result, but here we need a word that explains the cause.

29 me

– Why it's right: The phrase let me know is very common in English and means 'tell me your answer'. We need the object pronoun me to refer back to Lucy.

– Why not 'I': We must use an object pronoun like me immediately after the action verb let, never the subject pronoun I.

30 for

– Why it's right: We use the preposition for when someone prepares, buys, or makes something to give to another person (make snacks for us).

– Why not 'to': We never say make something to someone; we always make something for someone.

25 to

– Why it's right: The verb 'want' is followed by 'to' and an infinitive verb when we talk about a desire or plan.

– Why not 'for': A common mistake is to say 'want for plan', but 'want' must always take 'to' before the next action.

26 on

– Why it's right: We always use the preposition 'on' when we talk about digital communication, like being 'on a video call', 'on the phone', or 'on the internet'.

– Why not 'in': We use 'in' for physical, enclosed spaces, not for digital calls or screens.

27 a

– Why it's right: We always use the indefinite article 'a' to complete the very common fixed phrase 'a lot of'.

– Why not 'the': We cannot say 'the lot of' because this expression always requires the letter 'a'.

28 Do

– Why it's right: We use the helper word 'Do' at the beginning of a question in the present simple tense with the pronoun 'you'.

– Why not 'Are': We use 'Are' with an -ing verb (like 'Are you playing?'), but 'want' is a simple verb that needs 'Do' to make a question.

29 in

– Why it's right: We use the preposition 'in' when we talk about someone or something being located inside large geographical areas like towns, cities, or countries.

– Why not 'at': We use 'at' for specific points or places (like 'at the bus stop'), but never for whole countries.

30 me

– Why it's right: The phrase 'let me know' is a very common fixed expression that means 'tell me' or 'give me information'.

– Why not 'I': We must use the object pronoun 'me' after the verb 'let', not the subject pronoun 'I', because Ben is the person receiving the information.

25 an

– Why it's right: We use the article "an" instead of "a" when the next word starts with a vowel sound, like "interesting".

– Why not 'a': You cannot say "a interesting" because it is difficult to say two vowel sounds right next to each other.

26 for

– Why it's right: When we want to show who or what receives a benefit, we say it is "important for" them, like "important for our security".

– Why not 'to': We can say "it is important to change them" (with a verb), but we use "for" before a noun like "security".

27 am / 'm

– Why it's right: We need the verb "am" to make the future plan "am going to" for the subject pronoun "I".

– Why not 'are': The word "are" is used for plural subjects like "we" or "they", but we cannot use it after "I".

28 them

– Why it's right: The word "passwords" is a plural noun, so we need the plural object pronoun "them" to replace it.

– Why not 'it': The word "it" is only used to replace a singular noun (just one password), but Alice is talking about all of their passwords.

29 Do

– Why it's right: We use the auxiliary verb "Do" at the beginning of a question in the present simple tense (Do you want).

– Why not 'Are': We use "Are" if the main verb ends in "-ing" (Are you wanting), but here we have the base verb "want".

30 at

– Why it's right: We always use the preposition "at" before a specific time on a clock, like "at five o'clock" or "at half past two".

– Why not 'on': We use "on" for days of the week like "on Monday", but never for times on a clock.
