Most EFL learners know CONJUNCTIONS are only AND, BUT, BECAUSE, UNLESS, BESIDES, SO, etc. Rarely do they know about CORRELATIVE CONJUNCTIONS, whereas these conjunctions often appear in the TOEFL test.
CORRELATIVE CONJUNCTIONS are:
1. Not only ….. but also …..
2. Both ….. and …..
3. Either ….. or …..
4. Neither ….. nor …..
5. Not ….. but …..
It needs concerning that we MUST put the same word after each conjunction. For instance, if we put NOUN after BOTH, we also put NOUN after AND.
1. I can NOT ONLY dance, BUT ALSO sing. (The word dance and sing are VERBS)
2. Tom wants BOTH to host them AND to entertain them. (The word to host and to
entertain are TO INFINITIVE)
3. She is EITHER pretty OR nice. (The word pretty and nice are ADJECTIVES)
4. I want NEITHER apples NOR oranges. (The word apples and oranges are NOUNS)
NOTE: NEITHER and NOR already have NEGATIVE meaning, so the sentence has to be in
5. They’re NOT mine, BUT hers. (The word mine and hers are POSSESSIVE PRONOUNS)
I hope what I write can be useful for those EFL learners, since these conjunctions do appear a lot in the TOEFL test.
