B2 First key word transformations: Part 4 practice

B2Reading & Use of English40 questionsUpdated

Key word transformations are Part 4 of B2 First Reading & Use of English: you rewrite a sentence so that it means the same, using a key word you are not allowed to change. Each item is worth two marks and is scored in two halves, so a half-right answer is still worth having. These forty items drill the grammar the task keeps returning to.

What this task tests

  • Passive structures, including have something done and impersonal passives.
  • Reported speech, and the verb patterns of report verbs such as warn, remind, suggest and apologise.
  • Conditionals and wishes, especially past regret with should have and wish plus past perfect.
  • Modal verbs of deduction and obligation: might have, must have, need not have, be allowed to.
  • Perfect aspect with for and since, and the first time structure.
  • Comparatives and so/such result clauses.
  • Phrasal verbs and fixed expressions used as paraphrase, such as call off and put off.
  • Verb patterns after common verbs: to-infinitive, -ing form or a that-clause.
  • Counting words accurately, since contractions count as two.
  • Reading the second sentence to the end, because the words after the gap decide the form.

How to do it

  1. Step 1:

    Read the second sentence to the very end first

    The words printed after the gap control everything. If the sentence ends with ‘to touch the paint’, the gap has to end with a form that takes a to-infinitive.

  2. Step 2:

    Identify the grammar being tested, not the meaning

    Ask what the key word usually belongs to. HAD points to a passive or a past perfect; WISH points to regret; UNLESS points to a negative conditional.

  3. Step 3:

    Do not change the key word in any way

    You may not add an ending, make it plural or turn it into another part of speech. If your answer needs ‘called’ and the key word is CALL, your structure is wrong.

  4. Step 4:

    Write the answer, then count the words

    Two to five words, and a contraction counts as two. Write ‘do not’, not ‘don’t’, so you can see the real count.

  5. Step 5:

    Check that nothing from the gap repeats the printed words

    Candidates often repeat a word that is already outside the gap. Read the whole sentence back as one piece to catch it.

  6. Step 6:

    Aim for the standard paraphrase, not a clever one

    The task has a predictable set of structures behind it. If your answer is unusual, it is probably longer than five words and probably wrong.

  7. Step 7:

    Split the item into its two halves

    The mark scheme gives a mark for each half, usually the structure and the lexical part. If you cannot see the whole answer, write the half you are sure of.

  8. Step 8:

    Keep tense and time reference from the first sentence

    The two sentences must mean the same, so a past event stays past. Changing the time is the fastest way to lose both marks at once.

  9. Step 9:

    Never leave an item blank

    A partial answer can score one of the two marks. An empty gap cannot score anything at all.

  10. Step 10:

    Budget around twelve minutes

    Six items at two marks each are worth more than the first three parts individually, so this part earns the extra time, but not at the cost of the reading texts.

Mistakes that cost marks

  • Not thisI haven’t seen Tom since three years.

    ThisI have not seen Tom for three years.

    For is used with a length of time and since with a starting point. The contraction would also count as two words.

  • Not thisShe warned us don’t touch the paint.

    ThisShe warned us not to touch the paint.

    Warn takes an object plus a to-infinitive, and the negative goes before to, not inside a reported command.

  • Not thisHe suggested to meet on Friday.

    ThisHe suggested meeting on Friday.

    Suggest is followed by an -ing form or a that-clause, never by a to-infinitive.

  • Not thisI wish I booked earlier.

    ThisI wish I had booked earlier.

    Regret about a finished past action needs wish plus the past perfect. The past simple after wish refers to a present situation.

  • Not thisThey made him to pay a fine.

    ThisHe was made to pay a fine.

    Make takes a bare infinitive in the active but a to-infinitive in the passive, which is exactly what the task likes to test.

  • Not thisIt was such hot that we stayed inside.

    ThisIt was such a hot day that we stayed inside.

    Such needs a noun phrase. With a bare adjective you need so: it was so hot that we stayed inside.

  • Not thisYou mustn’t to use your phone here.

    ThisYou are not allowed to use your phone here.

    Modal verbs never take to, and the key word ALLOWED forces the be allowed to structure instead.

Frequently asked questions

How many marks is each transformation worth?

Two, awarded in two halves. That is why a partially correct answer is always better than a blank, and why this part rewards writing something even when you are unsure.

Do contractions count as one word or two?

Two. Write the full form while you are working so that you can count honestly, then leave it in full.

Can I change the key word?

No, not in any way. If you find yourself wanting to add -ed or -ing to it, your structure is wrong and you should look for a different paraphrase.

What if two answers seem possible?

Choose the one that uses the most standard structure and the fewest words. The task is built around a known set of grammar points, so the ordinary answer is almost always the intended one.

Which grammar should I revise for this part?

Passives, reported speech, conditionals and wishes, modal perfects, and the comparative and result patterns. Those five areas cover the large majority of items.

How much time should Part 4 take?

About twelve minutes for six items. It carries more marks per item than Parts 1 to 3, so it deserves a slightly slower pace, but not at the expense of the reading texts that follow.
