Question:到底什么是宾语从句？今天老师讲宾从的时候我认为老师讲错了，他说凡是在动词或动词短语后面的都是宾语从句，但我认为只有一个句子做宾语成分才是宾语从句
另外关于一个句子，我们有不同的理解
He is talking about when he will come.
我认为is talking是做谓语的
但是！！他竟然说is是系动词，因为talking about是短语动词，所以后面是宾从？？
还说我理解的是错的。。。（因为我在上课的时候提出来了）我不知道该如何反驳
最后他给我了个句子来佐证他的观点
He often wonders if he has the ability to teach what he has learned to the children there.（可能个别单词有错误）
他说what引导的是宾从，因为在teach后边，而teach是v.，所以是宾从。
所以到底谁说的对？
求解！！！
本人现在初三，谢谢了！！！
补：我认为be是助动词，和talking一起构成谓语（时态？）
alexcwlin/Adam Lam讨论英语语法最好是用英语解释，你试试看得明与否，不明再回来发问。Let me answer your questions one by one.
A. What is “宾语从句 Object Dependent Clause”An Object Dependent Clause is a Dependent Noun Clause that serves as an Object of a Transitive Verb.Here are the grammar rules that define this term:
1. Each Transitive Verb must be followed by an Object (Note 1).
2. An Object is a Noun, Pronoun, Noun Phrase, or a Noun Clause (Note 2).
3. A Dependent Noun Clause must have a Subject and a Tensed Verb (Note 3).
4. Dependent Clause is introduced by a Subordinating Conjunction or a Relative Pronoun (Note 4)
It may be a bit complicated for you, and you can read my notes if you want to know more about Clauses (Note 5)
B. 动词和宾语从句的关系Your teacher said: “All Verbs and Verb Phrases are followed by Object Dependent Clauses”老师说: 凡是在动词或动词短语后面的都是宾语从句You said: “Only clauses serving as Objects are Object Dependent Clauses”.你说: 只有一个句子做宾语成分才是宾语从句You are correct. Your teacher is wrong.For this discussion, there are three types of Verbs:
a. Transitive Verbs: Only Transitive Verbs have to be followed by Objects (Comment: Therefore not all Verbs are followed by Object Dependent Clauses, only Transitive Verbs are) and Objects come in the form of Nouns, Pronouns, and Noun Phrase, and Noun Clauses (Comment: therefore not Dependent Noun Clauses only).
b. Intransitive Verbs: Intransitive Verbs are not followed by Objects (Comment: Therefore, your teacher is wrong to say “All Verbs and Verb Phrases are followed by Object Dependent Clauses”)
c. Linking Verbs: Linking Verbs are followed by Subject Complements, not Objects (Comment: Therefore, your teacher is wrong to say “All Verbs and Verb Phrases are followed by Object Dependent Clauses”)
C. Nature of “is talking about”In “He is talking about when he will come.”You said: “is talking” is “Verb谓语”.Your teacher said: “is” is “Linking Verb系动词”, and “talk about” is “Verb Phrase 短语动词”My Take:You are correct. Your teacher is wrong.This is a Present Progressive Tense Verb Phrase, which is made up of:Verb to be (“is”) + Present Participle (“talking”) (Note 6)
“about when he will come” is a Prepositional Adverbial Phrase providing information on the contents of the Verb “talking” with “about” as the Preposition and “when he will come” is a Noun Clause—Object of the Preposition “about”.
D. “He often wonders if he has the ability to teach what he has learned to the children there.”Here “teach” is a Transitive Verb, and “what he has learned to the children there” is a Dependent Noun Clause which coincides with your teacher’s argument.But it doesn’t mean:
a. “Intransitive Verbs” and “Linking Verbs” do not have Objects;
b. not all Objects are “Dependent Noun Clauses”, because Objects could be Nouns, Pronouns and Noun Phrases.
除非你听错，否则：你的英语语法见解很准确，值得赞扬。你的老师英语能耐值得怀疑。但做人要有素质，不要当众反驳你的老师，否则他怎么下台呢？偷偷地给这里我的评语他看，问他的意见如何。Note 1: Transitive Verb followed by an Object:https://www.grammarly.com/blog/transitive-verbs/#:~:text=Transitive%20verbs%20require%20a%20direct%20object%20to%20form%20a%20complete,and%20before%20the%20direct%20object.
