A2 Key for Schools (KET) Reading & Writing Part 5 Test – Future Streams: Planning Tech Purchases & Digital Catch-ups 4

25 because

– Why it's right: We use because to give the reason for something. Having too many photos is the reason the cloud storage is full.

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

26 of

– Why it's right: We must use the preposition of to complete the fixed phrase a lot of, which means a large number or amount.

– Why not 'from': We never use the word from to describe a quantity; the correct English phrase is always a lot of.

27 on

– Why it's right: We always use the preposition on when we talk about specific days of the week, like Saturday.

– Why not 'in': We use in for months or years (like in August), but we never use it for a specific day.

28 a

– Why it's right: We use the indefinite article a because Lily is talking about one single film, and she hasn't mentioned exactly which film it is yet.

– Why not 'the': We only use the when both people already know exactly which specific thing is being talked about.

29 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.

30 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 Lily.

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

25 at

– Why it's right: We always use the preposition 'at' when we are talking about a specific clock time.

– Why not 'in': We use 'in' for months or parts of the day (like 'in the morning'), but we never use it right next to exact times like 9 o'clock.

26 me

– Why it's right: We need an object pronoun here because Peter is the person receiving the money from Sam.

– Why not 'I': We must use 'me' after a verb when an action is happening to the person, whereas 'I' is only used as a subject performing the action.

27 to

– Why it's right: The phrase 'going to' is followed by a base verb (like 'be') when we talk about future plans or predictions.

– Why not 'for': A common mistake is to say 'going for be', but we must always use the infinitive 'to' before the next verb.

28 than

– Why it's right: We use 'than' after a comparative adjective (like 'better', 'taller', or 'faster') when we are comparing two things or groups.

– Why not 'that': 'That' looks and sounds very similar, but it is not used for comparing things in English grammar.

29 if

– Why it's right: We use 'if' when there is a choice or when we are asking whether a fact is true or not (yes or no).

– Why not 'that': Saying "tell me that you can still come" sounds like an instruction or an order, but Peter is politely asking a question about Sam's plans.

30 a

– Why it's right: We always use the indefinite article 'a' in the very common fixed expression 'have a great time' or 'have a good time'.

– Why not 'the': We use 'the' for specific things we already know about, but this is a general phrase describing an experience.

25 a

– Why it's right: We use the article "a" to talk about a single, general thing for the first time, like "a fantastic new app".

– Why not 'the': We use "the" when the other person already knows which app we are talking about, but Maya hasn't heard about this one yet.

26 am / 'm

– Why it's right: We need the verb "am" to make the present continuous tense (am planning) 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".

27 because

– Why it's right: We use "because" to give a reason for a situation. They don't have to pay anything, and the reason is that the app is free.

– Why not 'so': We use "so" to show the result of something, but the second half of this sentence is the reason, not the result.

28 Would

– Why it's right: We always use "Would" with the phrase "you like to" when we want to invite a friend to do something in a polite way.

– Why not 'Do': We ask "Do you like" to ask about someone's general hobbies, not to invite them to do a specific activity.

29 on

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

– Why not 'in': We use "in" for months and years, but we never use it for specific days.

30 me

– Why it's right: Zoe is talking about herself, and we need the object pronoun "me" after the action verb "let".

– Why not 'I': The word "I" is a subject pronoun, which means it starts a sentence before a verb, but it cannot come after the verb.
