Transformation of Sentences Test 28

An effective way to make language more emphatic when using English is by inverting a sentence's normal word order.
For example, 'I have never eaten such a flaky croissant.' is a regular sentence, with the word order: subject (I) + verb (have never eaten) + object (such a flaky croissant).
To add emphasis, the auxiliary verb comes before the subject: Never have I eaten such a flaky croissant. ('Never' is an adverb and the main verb is 'eaten')
In option A, the sentence has the word order: auxiliary verb (Had) + subject (I) + main verb (known) + object + clause. The sentence has altered the normal word order, hence option A is correct.
Option B is incorrect because the sentence has the normal word order, beginning with the subordinating conjunction "If", followed by the subject and the rest of the sentence.
Options C and D also have the normal word order, with the addition of the phrase "I wish" and the adverb "Only", hence they are incorrect.

Option B is incorrect because the adverb is placed after the subject 'body temperature', and not after the adjective "high".
Option C is incorrect because the adverb is placed at the end of the sentence. Adverbs of frequency are not placed at the end. It must be placed as close to the word it modifies (in this case, "high").
Option D is incorrect because the adverb is placed in the front position of the sentence. Adverbs that intend to modify an entire sentence are only placed at front, whereas the underlined adverb modifies only the adjective.
