初中英语语法重要知识点 篇一

One of the most important grammar points in English is the proper use of verb tenses. Understanding verb tenses is crucial for conveying the correct timing of actions and events in a sentence. There are three main verb tenses in English: past, present, and future. Each tense has different forms and is used for different purposes.

The past tense is used to talk about actions or events that have already happened. For regular verbs, the past tense is formed by adding "-ed" to the base form of the verb. For example, "walk" becomes "walked" in the past tense. Irregular verbs, however, have unique past tense forms that do not follow this pattern. For example, "go" becomes "went" in the past tense.

The present tense is used to talk about actions or events that are happening now or that happen regularly. The present tense is also used to express general truths. For example, "I walk to school every day" uses the present tense to talk about a regular action, while "The sun rises in the east" uses the present tense to express a general truth.

The future tense is used to talk about actions or events that will happen in the future. The future tense is often formed using the auxiliary verb "will" followed by the base form of the verb. For example, "I will go to the store tomorrow" uses the future tense to talk about a future action.

In addition to verb tenses, another important grammar point in English is subject-verb agreement. This means that the subject of a sentence must agree with the verb in terms of number and person. For example, if the subject is singular, the verb must also be singular. Similarly, if the subject is plural, the verb must be plural as well. For example, "He goes to school" uses a singular verb form, while "They go to school" uses a plural verb form.

Understanding and using verb tenses and subject-verb agreement correctly are essential for clear and effective communication in English. By mastering these important grammar points, students can improve their writing and speaking skills and communicate more effectively in a variety of situations.

Another important grammar point in English is the proper use of articles. Articles are small words like "a," "an," and "the" that are used to indicate whether a noun is specific or general. "A" and "an" are indefinite articles, while "the" is a definite article.

Indefinite articles are used to refer to non-specific nouns. "A" is used before words that begin with a consonant sound, while "an" is used before words that begin with a vowel sound. For example, "a book" and "an apple" use indefinite articles to refer to any book or any apple, not a specific one.

Definite articles are used to refer to specific nouns that the speaker and listener both know about. "The" is used before singular and plural nouns to indicate that the noun is specific. For example, "the book on the table" refers to a specific book that is known to both the speaker and the listener.

It is important to use articles correctly to avoid confusion and make your writing and speaking more precise. Using the wrong article or omitting an article altogether can change the meaning of a sentence. For example, "I saw a cat" and "I saw the cat" have different meanings – the first sentence refers to any cat, while the second sentence refers to a specific cat.

In addition to articles, understanding and using prepositions correctly is also important in English grammar. Prepositions are words that show the relationship between a noun or pronoun and other words in a sentence. Common prepositions include "in," "on," "at," "by," and "with." For example, "I am in the classroom" uses the preposition "in" to show location, while "I go to school by bus" uses the preposition "by" to show means of transportation.

By mastering the proper use of articles and prepositions, students can improve their English language skills and communicate more effectively in both written and spoken English. These important grammar points help to clarify meaning and make communication more precise and accurate.

　　初中英语语法大全：动词的种类

　　关于英语中动词的种类知识，希望同学们很好的掌握下面的内容学习。

　　动词的种类

　　动词是表示动作或状态的词，按其词义和在句子中的作用可分为行为动词，连系动词，助动词和情态动词。

　　1．行为动词

　　行为动词可分为及物动词 (vt)和不及物动词(vi)，及物动词表示动作或状态，有完整的词义，能单独作谓语，后跟宾语；不及物动词表示动作或状态，有完整的词义，能单独作谓语，但后面不能直接跟宾语，如要带宾语则与介词或副词构成短语。

　　如：

　　More and more people study English.(vt)

　　The students are listening to the teacher carefully.(vi)

　　2．连系动词

　　连系动词本身有一定的词义，但不能独立作谓语，必须与表语一起构成谓语。常用的连系动词有 be, get, turn, become, look, feel, grow, seem, sound, taste, smell等。

　　如：

　　Our country is becoming stronger and stronger.

　　It feels damp.

　　3．助动词

　　助动词本身无词义，不能单独作谓语，只能和主要动词一起构成谓语动词，表示否定，疑问及动词的时态、语态、人称和数等语法特征，助动词有 be,do,have,shall,will等。

　　如：

　　How do you usually come to school?

　　The children are playing yo-yo now.

　　4．情态动词

　　情态动词本身有一定的意义，但不能独立作谓语，只能和主要动词原形一起构成谓语，表示说话人的语气和情态。情态动词没有人称和数的变化。情态动词有 can (could),may(might),must, need, ought to, dare等。

　　如：

　　Can I help you?

　　- Must we go now? -No, you needn't .

　　a. can与be able to的用法有所区别。can只用于一般现在时和过去时，指本身有能力的'"能"；be able to用于各种时态均可，指须经过努力而"能"。

　　b. must与have/has to的用法。must表示说话人主观认为"必须"，只用于一般现在时和一般将来时；have/has to表示客观需要，意为"不得不"，它可用于各种时态。

　　c．need和dare既可作情态动词也可作行为动词。

　　以上对动词的种类知识的内容讲解学习，相信同学们已经能很好的掌握了吧，希望同学们在考试中取得很好的成绩。

　　初中英语语法大全：动词不定式的形式

　　对于英语的学习中，关于动词不定式的形式知识点的内容，我们做下面的讲解学习哦。

　　动词不定式的形式

　　1．作主语。 如：

　　To learn English is very important.

　　但实际上不定式作主语常用 it来作形式主语，而将不定式移至谓语动词后作真正的主语。

　　如上句可表达为：

　　It's very important to learn English.

　　2．作表语。 如：

　　My idea is to ring him up at once.

　　3．作宾语。 如：

　　I have decided to go to Binjiang Primary School.

　　4．作宾语补足语。

　　a. ask, want, teach, tell, know, would like, allow等动词后面接动词不定式作宾语补足语。

　　如： The policemen asked him to get off the bus.

　　b. hear, see, look at, feel, watch, notice, listen to等动词后接不带to的动词不定式作宾语补足语。

　　如： We often see Miss Li clean the classroom.

　　c. let, make, have这些使役动词后接不带to的动词不定式作宾语补足语。但在被动语态中这些不带to的都须带上to。

　　如： In those days the bosses often made the workers work day and night.

　　d.动词help接动词不定式作宾语补足语，可带to也可不带to。

　　如： Can you help me (to) carry the heavy bag?

　　5．作定语。

　　a.与被修饰词有动宾关系。如：I have something important to tell you.但如果不定式动词为不及物动词，后面的介词千万不要省略。

　　如： Maybe they have three rooms to live in.

　　b.与被修饰词有主谓关系。

　　如： Mr Liang is always the first to come and the last to leave.

　　c.与被修饰之间只有修饰关系。

　　如： I have no time to play cards.

　　6．作状语，表示目的、原因、方法、方向、结果等。

　　如： I'll go to meet my friend at the railway station.

　　7．不定式复合结构"for sb. to do sth" 作主语时，常用"It is +adj+ for

　　of sb. to do sth"的句式。形容词good, bad, polite, unkind, kind, ice, clever,

　　right, wrong, careful等用"It is +adj +of sb. to do sth."

　　其他形容词用 for。

　　如：

　　It's dangerous for you to ride so fast.

　　It's very kind of you to help me.

　　8．动词不定式与疑问句who, what, which, when, how, where, whether等连用。

　　如： I don't know when to start.

　　He didn't tell me where to go.

　　但上面结构相当于一个从句，故上述句子也可表达为：

　　I don't know when we'll start.

　　He didn't tell me where he would go.

　　注意：

　　a.有些动词或动词短语不能带不定式，只能接动词的-ing形式。

　　如： enjoy, finish, keep, mind, miss(错过),be busy, go on, keep on, be worth, practise等。

　　如： The peasants are busy picking apples.

　　Would you mind my opening the door?

　　b.有些动词后可接不定式，也可接动词的-ing形式，但意思不同。

　　如： Lu Jian forgot to post the letter.(该寄但还没做)

　　Lu Jian forgot posting the letter.(已经寄过信了)

　　They stopped to sing a song.(停止在做的工作而去做另一件工作)

　　They stopped singing.(停止正在做的工作)
