Concept of object clause: A clause that plays the role of object in a sentence is called an object clause. Object clauses can be divided into three categories, object clauses of verbs, object clauses of prepositions and object clauses of adjectives.
1. There are only three situations for an object clause after a verb. One is that the object clause is directly followed by the verb; the other is that some "verb + adverb" structures can be followed by an object clause; the third is that the verb phrase can be followed by Object clause.
Example: I hope you can join us in the game. I hope you can join us in the game. (With an object clause directly after the verb)
Can you figure out what the poet really means in the poem? Can you understand the poet’s true intention in this poem? (verb + adverb structure followed by an object clause)
Make sure that there are no mistakes in your papers before you turn them in. Make sure that there are no mistakes in your papers before you turn them in. (Add an object clause after the verb phrase)
2. Object clause after the preposition
Example: She is always thinking of how she can do more for others. She is always thinking of how she can do more for others. Do more for others.
3. Object clause after adjectives
Example sentence: I am sure that they will make it in spite of the terrible weather. I am sure that they will succeed despite the terrible weather.
Extended information:
The introductory words of the object clause include that, if/weather, and wh-type connectives. Among them, that has no word meaning when it introduces the object clause, and does not add any components in the clause, and can generally be omitted in spoken language; when if/weather introduces the object clause, it does not add any components in the sentence, but has a specific meaning, meaning whether or not, and cannot be omitted; The wh-type connectives include connecting pronouns (who, whom, what, which, whoever, whichever, etc.) and connecting adverbs (when, where, why, how, whenever, wherever, however, etc.).
