📋 How to use this lesson

For Teachers

Display the 4-row rule table for four minutes of guided review before practice.

Have learners complete the 12 tasks independently and check answers with the short feedback notes.

For Learners

First, read through each pattern in the rule table and examine how the food examples work.

Next, solve all 12 practice tasks below and use the one-word hint if you get stuck.

Core Patterns: How the pairs work

Four paired connectors to join ideas, show options, or add emphasis.

1

both ... and

Use this pair to connect two things that are true together. It always takes a plural verb because you are talking about two parts at once. Keep the words after both and after and in the same grammatical pattern. Never use a singular verb with this structure.

🔹 "Both fresh fruit and plain nuts make a good snack."

🔹 "Both high sugar intake and artificial additives harm your dental health."

✅ Do: Both fibre and protein are essential.
⚠️ Avoid: Both fibre and protein is essential.
2

either ... or & neither ... nor

Use either ... or to offer a choice between two possibilities. Use neither ... nor to mean not the first one and not the second one. Because neither ... nor is already negative, your verb must stay positive. The verb always agrees with whichever noun sits nearest to it.

🔹 "Neither my brother nor my parents eat meat."

🔹 "Either small portions or a high-fibre salad satisfies your appetite."

✅ Do: Neither the burger nor the chips contain clean nutrients.
⚠️ Avoid: Neither the burger nor the chips don't contain clean nutrients.
3

whether ... or

Use whether ... or to introduce two different situations or possibilities when the overall fact or outcome remains the same. In this paired structure, always use whether rather than if. Do not pair whether with nor.

🔹 "Whether you cook at home or eat out, check what is in your food."

🔹 "Whether a meal contains animal protein or plant protein, your body absorbs the nutrients."

✅ Do: Whether you buy organic or regular food, wash it well.
⚠️ Avoid: If you buy organic or regular food, wash it well.
4

not only ... but also

Use this pair to add a second, often more surprising or important point to the first one. When not only is placed at the very start of the sentence for emphasis, invert the first clause: put the auxiliary verb before the subject, just like in a question. Keep the second half in normal statement order.

🔹 "Not only does this drink contain a lot of sugar, but it also costs more."

🔹 "Not only is lean chicken packed with protein, but it also cuts late-night cravings."

✅ Do: Not only is it sweet, but it is also addictive.
⚠️ Avoid: Not only it is sweet, but it is also addictive.
