A2 Key for Schools (KET) Reading & Writing Part 5 Test – Travel Hiccups: Apologies & Changing Routes 4

25 going

– Why it's right: We use "going" with the verb "to be" (am) and "to" when we want to talk about a future plan or a sure event.

– Why not 'will': You cannot say "am will"; the modal verb "will" is never used together with the verb "to be" in this way.

26 on

– Why it's right: We use the preposition "on" with the verb "get" when we talk about entering large public transport like a train, bus, or plane.

– Why not 'in': We say "get in" for a small private vehicle like a car or taxi, but we must say "get on" a train.

27 for

– Why it's right: We use the preposition "for" to talk about the length or duration of time that an action lasts, like "twenty minutes".

– Why not 'since': We use "since" to give the exact starting point of a time (like 8 o'clock), but not for an amount of time.

28 but

– Why it's right: We use the conjunction "but" to connect two different or contrasting ideas, like being lost and having a map to help fix it.

– Why not 'because': "Because" is used to give a reason, and having a map is not the reason why Lucas is lost.

29 the

– Why it's right: We use the definite article "the" when we are talking about one specific thing, like "the next station" on the train track.

– Why not 'a': There is only one next station on the line, so it is a specific place, not a general one.

30 an

– Why it's right: We use the article "an" before singular nouns that begin with a vowel sound, like the silent 'h' in the word "hour".

– Why not 'a': We cannot use "a" because "hour" starts with an 'o' vowel sound, not a hard consonant sound.

25 for

– Why it's right: We use the preposition "for" after the phrase "thank you" when we are talking about an action someone did.

– Why not 'to': We cannot use "to" directly before an "-ing" word like "inviting" in this kind of sentence.

26 but

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

– Why not 'because': Using "because" would mean the reason she wants to come is that she cannot go, which makes no sense.

27 at

– Why it's right: We use the preposition "at" to complete the fixed phrase "at home", which we use to talk about being inside our own house.

– Why not 'in': We can say "in the house" or "in my room", but we must always use "at" with the word "home".

28 the

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

– Why not 'a': We cannot use "a" because superlatives describe one specific, unique thing that stands out from everything else.

29 are

– Why it's right: We need the auxiliary verb "are" to complete the "are going to" structure, which we use to talk about future plans with the pronoun "we".

– Why not 'will': You cannot use "will" right before the word "going"; you must use a form of the verb to be.

30 me

– Why it's right: "Let me know" is a very common fixed phrase that simply means "tell me". We must use the object pronoun "me" to receive the action.

– Why not 'I': "I" is a subject pronoun, so it cannot be placed right after an action verb like "let".

25 to

– Why it's right: We use to before a base verb (apologize) to show the reason or purpose for doing something. James is writing to do something.

– Why not 'for': We cannot use for before a base verb; saying writing for apologize is grammatically incorrect in English.

26 but

– Why it's right: We use the linking word but to connect two contrasting ideas. James left it on his desk, so it should be there, but the opposite is true.

– Why not 'so': We do not use so because it introduces a result, and it missing is not the direct result of putting it on the desk.

27 on

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

– Why not 'in': We use in for months or years, but never for specific days.

28 a

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

– Why not 'the': The phrase is fixed as a lot of; saying the lot of is incorrect when asking about quantity here.

29 them

– Why it's right: We need the object pronoun them to replace the plural noun photos so we do not have to repeat the word.

– Why not 'it': We don't use it because photos is a plural word, and it is only used for singular nouns.

30 be

– Why it's right: We need the base verb be to complete the future tense structure will be to describe what seeing the pictures is going to be like.

– Why not 'is': We cannot use is because the verb to be must always stay in its base form after the modal verb will.
