I don't approve of his driving of the car.
According to my text book, "his driving" cannot take the object "the car" directly, instead it needs "of" to put the object as in the sentence. Another example shown there is
The mere knowing of his name is a small thing. (Conan Doyle, A Study in Scarlet)
Again, it says "the mere knowing" cannot take the object "his name" directly. But, I don't understand why.
His driving the car isn't wrong. The book might be wrong. It depends on whether the book is talking about nouns in particular.
Gerund-participle clauses
We can use a gerund-participle clause in many of the same situations where we use noun phrases. We can use them as Subjects, Objects and as the Complements of prepositions. A gerund-participle clause is a clause which uses an -ing form of the verb with no (present or past tense) auxiliaries. The part in brackets below is a gerund-participle clause:
Gerund participle clauses can have either normal noun phrases, or genitive ones using 's or s' as Subject:
If the Subject of the gerund-participle clause is a pronoun, we can use an accusative one or a genitive one:
Notice that gerund-participles are verbs not nouns. Because of this, they take Direct Objects. We use adverbs and not adjectives to modify the -ing verb:
In both sentences above we see the Direct Object my Ferrari and the adverb carefully. Notice that if we use the adjective careful to modify the verb the sentence will be ungrammatical:
Nouns
Many nouns in English describe actions:
Nouns do not take Direct Objects. If we want to show the people or things that these actions were done to, we need to use a preposition phrase using the preposition of:
If we want to modify nouns, we need to use adjectives, not adverbs:
Noun phrases in English often have Determiners. These are words like a or the that do a special job in noun phrases. We can use genitive noun phrases using 's or s' as Determiners. We cannot use plain form ones:
We can use genitive pronouns as Determiners. We cannot use accusative or nominative ones:
Of course we can always use determiners like the:
Nouns ending in -ing
In English we can use different endings to turn verbs into nouns. For example we can add -(a)tion on to many verbs to make a new noun:
We can also make new nouns from almost any verb by adding -ing to the plain form of the verb:
These look exactly the same as gerund-participles, but they are not verbs. Like all nouns, they take preposition phrases with of instead of Objects:
Like other nouns they can take genitive noun phrases and prepositions as Determiners. They cannot take normal nouns or accusative or nominative pronouns as Determiners:
Of course, we can always use the as a Determiner:
Like other nouns, these nouns can be modified by adjectives. They can't be modified by adverbs:
If we use these noun -ing forms as nouns, then they are nouns, not verbs!
The Original Poster's question
- I don't approve of his driving of the car.
- I don't approve of his driving the car.
The first sentence uses the noun driving. It has a preposition phrase to show what he was driving. The second sentence uses the gerund-participle form of the verb, driving. Because it's a verb it takes a Direct Object.
Notice that we can use the instead of his as a Determiner in (1). Also we cannot use the accusative him as a Determiner:
Notice that we can use him as a Subject in (2). Obviously we can never use the as the Subject of a verb;
Lastly, notice that we can use an adjective as a modifier in (1) because driving is a noun. We can't use an adverb. In (2) where driving is a gerund-participle verb, we can use an adverb as a modifier but not an adjective:
(1) I don't approve of his careless driving of the car. (noun with adjective)
(1) *I don't approve of his carelessly driving of the car. (noun with adverb, wrong)
(2) I don't approve of his carelessly driving the car. (verb with adverb)
(2) *I don't approve of his careless driving the car. (verb with adjective, wrong)
So, in the Original Poster's example, driving could be a verb or a noun. If it is a noun, it takes a preposition phrase, of the car. If it is a verb it can take a Direct Object, the car. If driving is a noun, the word his is a Determiner. If driving is a verb, we probably want to think of his as a Subject.
Hope this is helpful!
Reference Note:
All of this information can be found in the Cambridge Grammar of the English Language, the famous reference grammar by Huddleston & Pullum (et al) 2002. You can also find most of it in A Student's Introduction to English Grammar, Huddleston & Pullum, (2005)
"Him driving" focuses on that person, "his driving" focuses on how that person drives. For example: "I don't agree with John driving to the shop" vs "I don't agree with John's slow driving to the shop".
It should also be noted that "the mere knowing of his name" would be "merely knowing his name" in a more modern setting. BrE and AmE have moved on since Conan Doyle, though Victorian phrasing can be rather poetic
