I am a second-year junior high school student. I want to distinguish words such as prepositions, adverbs, verbs, adjectives, etc. and some grammar, such as why not + verb base form, etc.

Prepositions (prepositions, referred to as prep), also known as prepositions, are one of the most active parts of speech in English, connecting subjects and predicates. In particular, some commonly used prepositions have very strong collocation power and can be used to express various meanings. Most idioms in English are made up of prepositions and other words. Prepositions are generally not stressed in sentences. In the structure of the attributive clause "preposition + who/which", you cannot use that instead of who/which. She is a good student from who we should learn.

Collocation of verbs and prepositions (or adverbs)

Adverb (adverb, abbreviated as adv) is a word used to modify verbs, adjectives, and entire sentences to describe time and place , degree, manner and other concepts. An adverb is a word that is half imaginary and half real. Adverbs can be divided into: adverbs of place, adverbs of manner, adverbs of degree, interrogative adverbs and connecting adverbs

Adverbs can be used as adverbials, predicates, complements and attributives in sentences.

He works hard. (as an adverbial) He works hard.

You speak English very well. (as an adverbial) You speak English very well.

Is she in? (Predicate) Is she at home?

Let's be out. (Predicate) Let's go out.

Food here is hardly to get. (as an adverbial) It is difficult to get food here.

Let him out! (as a complement) Let him out! .

Adverbs that modify nouns are placed after the modified word a. The villagers there are busy getting in wheat

Position

1) Before the substantive verb, After be verb and modal verb.

I am also Bush.

I can also do that.

I also want to play that games.

2) Adverbs modify adjectives. When used as adverbs, the adverb comes in front and the word being modified comes in the back.

It's rather easy, I can do it.

He did it quite well. He did it quite well.

It's rather difficult to tell who is right.

3) Frequency adverbs can be placed in front of substantive verbs and after modal verbs and auxiliary verbs.

I often help him these days. I often help him these days.

I always remember the day when I first came to this school. You mustn't always help me.

4) Interrogative adverbs, connecting adverbs, relative adverbs and adverbs that modify the entire sentence are usually placed in front of the sentence or clause. When do you study everyday?

Can you tell me how you did it?

First, let me ask you some questions. Let me ask you some questions first.

How much does this bike cost? How much does this bike cost?

Either you go or he comes. Either you go or he comes.

5) When adverbs of time and adverbs of place are in the same sentence, the adverbs of place come first and the adverbs of time come last.

We went shopping in the supermarket at 9 o'clock yesterday. What were you doing in the classroom yesterday afternoon? What were you doing in the classroom yesterday afternoon? 6) The negative adverb is at the beginning of the sentence, and the sentence should be inverted,

For example: Never have I felt so excited! I have never felt too excited!

Verbs are words used to describe or express various actions. Basically, every complete clause has a verb. To express the second action, it can be connected by using infinitives, gerunds, equivalent connectives, subordinating connectives or adding clauses.

Words that express actions and states are called verbs.

1) According to their functions in sentences, verbs can be divided into four categories:

They are: Notional Verb, Link Verb, and Auxiliary Verb (Auxiliary Verb), modal verb (Modal Verb). It can also be divided into transitive verbs and intransitive verbs. Note: In some cases, some verbs are concurrent words, for example: We are having a meeting. We are having a meeting. (Having is a real verb.) He has gone to New York. He has gone to New York. (has is an auxiliary verb.

)

2) Verbs are divided into two categories according to whether they have an object after them.

They are: transitive verbs (Transitive Verb) and intransitive verbs (Intransitive Verb). The abbreviations are vt. and vi. respectively. Explanation: The same verb can sometimes be used as a transitive verb and sometimes as an intransitive verb. For example: She can dance and sing. She can sing and dance. (sing is used as an intransitive verb here.) She can sing many English songs. She can sing many English songs. (sing is used as a transitive verb.)

3) Depending on whether it is restricted by the person and number of the subject

They are: finite verb (Finite Verb), non-finite verb (Non -finite Verb) For example: She sings very well. She sings very well. (Sing is restricted by the subject she, so the third person singular form sings is used.) She wants to learn English well. She wants to learn English well. (To learn is not restricted by the subject she, has no morphological changes, and is a non-finite verb. Note: There are three types of non-finite verbs in English, namely: verb infinitive (Infinitive), gerund (Gerund), and participle ( Participle).

4) According to the form of verbs, they can be divided into three categories:

One-Word Verb and Phrasal Verb. , Verbal Phrase (Verbal Phrase) For example: The English language contains many phrasal verbs and verbal phrases. There are many phrasal verbs and verbal phrases in English. (Contains is a one-word verb.) Students should learn to look up new words in dictionaries. Students should learn to look up new words in dictionaries. (Look up is a phrasal verb.) The young ought to take care of the old. (Take care of is a verb phrase.)

5) Verbs have five forms,

namely: Original Form, Singular Form in Third Personal ), past tense (Past Form), past participle (Past Participle), present participle (Present Participle).

Adjective, referred to as adj. or a., is one of the main parts of speech found in many languages. Words mainly used to modify nouns to express the characteristics of things. Adjectives are used to modify nouns or pronouns to express the nature, state, and degree of characteristics of people or things, good or bad, or not.

Adjectives serve as attributives, predicatives, and object complements in sentences. She is a good student, and she works hard. She is a good student, and she works hard. This bike is expensive. This bike is expensive. I am sorry, I'm busy now. Sorry, I'm busy now. Have you got everything ready for the meeting? Have you got everything ready for the meeting? The position of the adjective in the sentence: Adjectives as attributives are usually placed before the noun they modify. If two or more adjectives modify a noun, the degree of closeness between them and the noun they modify is determined. The closer the adjective is, the closer it is to the noun. If several adjectives are of similar closeness, the adjective with fewer syllables is placed first, and the adjective with more syllables is placed later. In English words, when indefinite pronouns such as something, anything, nothing, etc. are modified by adjectives, the adjective is placed after the indefinite pronoun. I have something important to tell you. I have something important to tell you. Is there anything interesting in the film? Is there anything interesting in the film? There is nothing dangerous here. There is nothing dangerous here.

An adjective phrase consisting of two or more words must be placed after the noun when modifying it. This is the book easy to read. This is the book easy to read. When two adjectives connected by and or or are used as attributives, they are usually placed after the noun they modify. Serve as further explanation. Everybody, man and woman, old and young, should attend the meeting. You can take any box away, big or small. You can take any box away, big or small. Comparative and superlative forms of adjectives: Most adjectives have three forms, primary, comparative and superlative, to express the difference in degree of the properties described by the adjectives. Comparative and superlative forms of adjectives: The comparative and superlative forms of adjectives change based on the primary form of the adjective. Divided into regular changes and irregular changes.

Rule changes

Adjective comparison Usage of degree

The comparative form of adjectives is used to compare two people or things. Its structure is as follows: subject + predicate (linking verb) + comparative adjective + than + contrasting component. That is, the main clause + than + clause containing the comparative form of the adjective. Note that cluster sentences often omit the parts that are the same in meaning as the main clause, leaving only contrasting elements. Our teacher is taller than we are. Our teacher is taller than we are. It is warmer today than it was yesterday. The weather today is warmer than yesterday. This picture is more beautiful than that one. This picture is more beautiful than that one.

Usage of the superlative form of adjectives

1. The superlative form of adjectives is used to compare two or more people and things. Its structural form is: subject+predicate (linking verb)+the+ Superlative adjective + noun + phrase or clause indicating range. (Often used with phrases expressing ranges of in and of) (Note: of + individual noun singular in + collective noun) eg 1)Shanghai is the biggest city in China. Shanghai is the biggest city in China. 2)He runs fastest in our class. He runs fastest in our class. 3)He is the tallest of the three boys. He is the tallest of the three boys. 4)Which is the easiest, Lesson1, Lesson2 or Lesson3? Which lesson is the easiest? Lesson one? Lesson 2? Or the third lesson? 2. When the superlative of an adjective means "second, third...", you can add "second, third,..." before the superlative (but "first" cannot be used) eg. The Changjiang River is the longest river in China. The Yangtze River is the longest river in China. The Yellow River is the second longest river in China. The Yellow River is the second longest river in China.

It's pity he is getting poorer and poorer. It's a pity that he is getting poorer and poorer. The computer is cheaper and cheaper. The computer is getting cheaper.

If you are not sure, you can refer to the following table: determiner + quantifier (ordinal number) in front, cardinal numbers in the back) + character adjectives + shapes such as size, length, height + those + three + beautiful + large + square old and new + color + nationality + material + noun old + brown + wood + table
