Negative, Double negative and Affirmative sentences Set-1 - Grade 7 Assessment

Which sentence is an affirmative sentence, meaning it states something is true or is happening?

• We aren't going to the game after all.

• My brother plays guitar in his room.

• She never finishes her homework on time.

• I have no snacks left for the trip.

Answer explanation

This is an affirmative sentence because it states a positive fact without using any negative words like 'not', 'never', or 'no'.

True or False: The word 'never' makes a sentence negative.

• True

• False

Answer explanation

The word 'never' is a negative adverb that means 'not ever' or 'at no time.' When used in a sentence, it makes the statement negative.

Make this sentence negative by filling in the blank with the correct word: My dad (a)   know how to fix the Wi-Fi.

Answer explanation

To make a present tense verb like 'know' negative, we use the helping verb 'do' with 'not'. For a singular subject like 'dad', the correct form is 'doesn't' (does not).

Which sentence contains a double negative, making it grammatically incorrect in standard English?

• I don't want any of that pizza.

• Nobody is at the bus stop yet.

• He couldn't find nothing to watch on TV.

• She is not my lab partner.

Answer explanation

This sentence uses two negative words, 'couldn't' (could not) and 'nothing', in the same clause. This is a double negative. The correct form would be 'He couldn't find anything to watch' or 'He could find nothing to watch'.

True or False: In formal writing and speaking, using two negative words like 'can't' and 'nothing' together in one clause is a correct way to make a statement.

• True

• False

Answer explanation

Using two negatives in the same clause, known as a double negative, is considered grammatically incorrect in standard English. It can cause confusion, and the sentence should be rephrased with only one negative.

Which sentence is grammatically correct and avoids a double negative?

• My dog won't eat no vegetables.

• My dog won't eat any vegetables.

• My dog won't never eat vegetables.

• My dog doesn't eat no vegetables.

Answer explanation

This sentence correctly uses one negative ('won't') with the word 'any' to express the idea. The other options all contain double negatives ('won't' + 'no', 'won't' + 'never'), which are incorrect.

To fix the double negative in the sentence 'I can't find my keys nowhere,' you should replace 'nowhere' with the word (a)   .

Answer explanation

In a negative sentence that already includes 'not' (in 'can't'), the word 'nowhere' should be changed to 'anywhere' to avoid a double negative and make the sentence grammatically correct.

Change the affirmative sentence 'She has some new video games' into a correct negative sentence by replacing 'some' with a single word: She has (a)   new video games.

Answer explanation

One way to make this sentence negative is to replace the positive word 'some' with the negative word 'no'. This creates a correct negative sentence: 'She has no new video games.'

The sentence 'He didn't say nothing' is a common double negative. To make it a correct negative sentence that means 'He was silent,' fill in the blank: He didn't say (a)   .

Answer explanation

The standard English way to express this idea is to use 'anything' after a negative verb phrase like 'didn't say.' The double negative 'didn't say nothing' is grammatically incorrect.

Which statement best explains the relationship between these two sentences? Sentence 1: There isn't any food in the fridge. Sentence 2: There is no food in the fridge.

• Sentence 1 is correct, but Sentence 2 is a double negative.

• Sentence 2 is correct, but Sentence 1 is a double negative.

• Both sentences are grammatically correct and have the same meaning.

• The sentences have opposite meanings.

Answer explanation

Both sentences are standard, correct ways to say that the fridge is empty. The structure 'is not any' is equivalent in meaning to the structure 'is no'. Neither sentence contains a double negative.
