English declarative sentences are changed to negative sentences, and English is changed to negative

In English, the sentence structure used to state facts, state opinions, affirm or negate is generally called declarative sentences, and its basic structure is similar to that of Chinese, with subject + predicate + object, for example, mike likes catsOr it is subject + verb + predicate, for example, he is a student

Declarative sentences are divided into affirmative declarative sentences and negative declarative sentences, and usually when the sentence contains words such as not, little, few, too, hardly, never, neither, nor, seldom, etc., it is regarded as a negative sentence.

For example, he was too excited to speakHe was so excited that he couldn't speak.

he is scarcely the right person for the job.He wasn't fit for the job at all.

he can hardly understand you.He can barely understand your words.

There are two main ways to change a positive declarative sentence to a negative declarative sentence:

It is usually not added after the verb be or modal verb.

he is a farmer.Changed to a negative sentence:

he is not a farmer.Or he isn't a farmer.

He is not a farmer.

he can dance.Changed to a negative sentence:

he can not dance.Or he can't dance.

He can't dance.

If there is no be verb or modal verb, the negative form of the auxiliary verb is used before the action verb, and it is necessary to pay attention to the corresponding change according to the tense and personal name, i.e., don't，doesn't，didn't, followed by the original form of the verb.

we always play basketball after school.Changed to a negative sentence:

we always don't play basketball after school.

We don't always play basketball after school.

he likes riding a bicycle.Changed to a negative sentence:

he doesn't like riding a bicycle.

He doesn't like to ride a bike.

The way to change a declarative sentence to a negative sentence is to have modal verbs, be verbs and auxiliary verbs in the sentence, and add not directly after these words, otherwise with the help of the auxiliary verb don't/doesn't/didn't, the following verb is in the original form, some is changed to any, and already is changed to yet

As. he is a student.

The negative sentence is he isn't a student.

There are three main ways to change a declarative sentence to a negative sentence in English:

Add not after the verb be.

Add not after the modal verb.

Add an auxiliary verb followed by a negative adverb not.

1. If there is a be verb in the sentence, add not after the be verb.

2. If there is a predicate verb in the sentence, add don after the subject't (if the subject is in the third person, add doesn.)'t, the three single words of the syncopated change are the prototype).

3. If there are modal verbs (such as can, may, etc.) in the sentence, add not after the modal verb.

4. If the sentence is composed of a sentence pattern such as needto, add not after the word need.

The negative sentence is changed in the following way:1. The affirmative sentence becomes a single negative sentence. Find out the antonym of the predicate first and then negate the antonym, e.g. after effort, these problems are easy to solve can be changed to after effort, these problems are not difficult to solve.

2. Affirmative sentences become double negative sentences. A double negative sentence is one that expresses an affirmative meaning, and the tone is stronger than that of a declarative sentence. Rephrasing by adding a double negative before the predicate verb is sufficient.

The method of substitution of double negative words is to replace "yes" and "has" with "no one can deny". "Certainly" and "must" are used as "non-......"Can't" and "can't not" replace.

When changing a negative sentence, it should be noted that the sentence that expresses the negative is called a negative sentence, and there must be a negative word in the negative sentence. Negative words can be adverbs, such as "no", "fu", "no", "don't", "not", "no", "not"; can be a verb, such as "nothing"; It can also be pronouns like "Mo". In ancient Chinese, if the object of a negative sentence verb is a pronoun, the object of this pronoun is generally placed in front of the verb, and there are mainly four words: "no", "no", "not" and "mo".

This is a syntax unique to ancient Chinese.

Generally speaking, to change an English sentence to a negative sentence, just add the negative word not.

An English negative sentence is a sentence that indicates a negation, and there must be a negative word. A negative sentence is only a negative sentence if there is a negative word. English negative sentences are a key point for Chinese to learn English, and it is also a difficult point. Only by breaking through these difficulties can we make a qualitative leap in English learning.

1. If there is a verb of be in the sentence (am is are were), add not after the verb be.

For example: i can swim——i can't swim.

he is a math teacher. →he is not a math teacher.

2. If there is a modal verb in the sentence (can should must would), add not after the modal verb;

For example: there will be a new building next year →there will not be a new building next year.

Will Not can be abbreviated as won't)

3. If there is no be verb and modal verb in the sentence, add don before the verb't or doesn't't

If the verb in the sentence is three singular, add doesn't't, and reverts the three-singular verb to its original form.

4. Some in the affirmative sentence should be changed to any in the negative sentence

For example: there are some students in the classroom there are not any students in the classroom.

1. Look at whether there is a be verb in the sentence, if so, directly after the be verb + not.

Namely: be verbs (am, is, are, was, were) + not,

Example: i am a teacherI'm a teacher.

Negative: i am not a teacher 我不人人。

2. Look at whether there is a modal verb in the sentence, if there is, directly after the modal verb + not

That is: modal verbs (can, must, should) + not,

He can help me.

Negative: he can't help me He can't help me.

3. If there is neither of the above, use the auxiliary verb + not

That is: auxiliary verbs (do, does, did) + not

put them over there.

Negative: don't put them over there.

1. Look at whether there is a be verb in the sentence, if so, directly after the be verb + not.

2. Look at whether there is a modal verb in the sentence, if there is, directly after the modal verb + not

3. If there are none of the above, use the auxiliary verb + not, in four steps:

1) In the affirmative statement, there is no auxiliary verb, and it should be added, after the subject (someone or something) and before the verb.

2) Make sure that the auxiliary verb uses do and does, according to the verb in the sentence, use do if the verb is the original form, use do if the verb is the third person singular auxiliary verb, and 3) add not after the auxiliary verb.

4) If the verb in the original sentence changes, it should be restored to its original form.

Note: To emphasize that if there is some, consider whether to use any.

I hope it helps you, if there are no other questions, can you give a like, thank you very much for asking what are the modal verbs.

Answer can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would).

Basically, not, no, is a negative word.
