function怎么记忆
洋老大-英语单词记忆课128语法重难点
1. Subject-Verb Agreement (主谓一致): In English, the verb must agree with the subject in terms of number. For example, "She plays soccer" is correct, but "She play soccer" is incorrect because the subject "she" is singular and the verb "play" is plural.
2. Verb Tenses (动词时态): English has several verb tenses, including the simple present, present continuous, simple past, past continuous, present perfect, past perfect, and future tenses. Each tense has specific rules for when and how it should be used.
3. Modal Verbs (情态动词): Modal verbs such as can, could, may, might, must, shall, should, will, would, and ought to are used to express ability, possibility, necessity, permission, suggestion, and preference.
4. Relative Clauses (定语从句): A relative clause is a dependent clause that starts with a relative pronoun (such as who, whom, whose, which, or that) and provides additional information about a noun in the main clause.
5. Conditional Sentences (条件句): Conditional sentences express hypothetical situations or consequences. There are four types of conditional sentences: zero conditional, first conditional, second conditional, and third conditional.
6. Passive Voice (被动语态): In the passive voice, the subject of the sentence receives the action of the verb. The structure of passive sentences is formed with a form of the verb "to be" + past participle of the main verb.
7. Reported Speech (间接引语): Reported speech is used to report what someone else has said. When reporting speech, it is important to change the verb tenses, pronouns, and adverbs to reflect the new speaker.
8. Prepositions (介词): 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, for, of, to, and from.
9. Comparative and Superlative Adjectives (比较级和最高级形容词): Comparative adjectiv
es are used to compare two things, while superlative adjectives are used to compare more than two things. The comparative form is usually formed by adding -er to the adjective, and the superlative form is formed by adding -est.
10. Gerunds and Infinitives (动名词和不定式): Gerunds are verbs that function as nouns, while infinitives are the base form of a verb preceded by the word "to". The choice between gerunds and infinitives depends on the verb that precedes them and the meaning of the sentence.
