Analyze the subject of the verb be adjective of the abstract meaning expressed by the infinitive

Be + adjective + infinitive is divided into two cases:

2. Predicative adjectives indicate the characteristic description of the subject, such as: easy, ready, slow, able, probably, etc. The infinitive after such adjectives indicates that the subject has this characteristic to do something or accept something, and the infinitives each have their own characteristics.

If it indicates that the subject has a certain characteristic to do something, the infinitive is a purely transitive or intransitive verb.

Application skills. 1. There are many meanings and usages of the verb be, and the general meaning is: yes, this usage, there are many variations, is, am, are, was, were, being, been, to be. In addition, the verb be also has the meaning of becoming.

According to the different person, number, time and form in the sentence, the corresponding be verb should be chosen.

2. When be is used as an auxiliary verb in a sentence, when it is used in conjunction with the present participle of the verb, it constitutes a continuous tense; When used in conjunction with the past participle of a verb, it forms a passive tense; When used in conjunction with the infinitive of a verb, it means intending to do something. When be is used as a verb in a sentence, the meaning is "to do, to have".

How should we understand the structure of "subject + be + adjective + infinitive"? Please answer in detail, thank you.

1. The following two sentences are just adjectives different, why does the first sentence mean "others please him", while the second sentence means "he pleases others"?

is easy to please.(He's easy to please.) Subject + be + adjective that indicates the characteristic of the event + to do sth first sentence:

The subject of the sentence is the logical object of the verb infinitive, and the active means that the passive meaning is eager to please(He loves to please people.) Subject + be + character nature characteristics and state characteristics adjective + to do sth second sentence, the sentence subject is the verb infinitive logical subject.

2. The meaning of the following two sentences is "he was deceived", why is the infinitive in the first sentence in the active form, and the infinitive in the second sentence in the passive form?

is easy to fool.(He's easily deceived.) Subject + be + adjective that indicates the characteristic of the event + to do sth first sentence:

The subject of the sentence is the logical object of the infinitive, and the active means that the passive meaning is afraid to be fooled(He was afraid of being scammed.) Subject + be + character nature characteristics and state characteristics adjective + to do sth second sentence, the sentence subject is the verb infinitive logical subject.

3. How should the following sentences be understood correctly?

is kind to help us.

is glad to help us.

dinner is ready to eat.

are ready to eat.

is slow to react.

is able to do it.

am willing to help you.

is likely to accept our help.

The first sentence is the infinitive active expression passive meaning, such words also have rent, wash, sell, clean, etc., and the subject is the object of the infinitive.

This reflects the flexibility of the language, some words are actively and passively used in the same word, and we have a similar situation in Chinese, for example: "This piece of meat is grilled and ready to eat." In fact, the sentence should be exactly: the meat is roasted and ready to be eaten.

It is difficult to summarize any rules for this kind of word, so accumulate more when you usually use it to master the sense of language.

The above sentences: 1. He was very eager to help us.

2. He was happy to help us.

3. The meal is ready to eat.

4. We're ready to eat.

5. He is very slow to react.

6. He can do it.

7. I'm willing to help you.

8. He seems to accept our help.

Subject + be + adjective noun is called the subject table structure.

This sentence structure is mainly used to indicate the identity, state, characteristics and position of the subject.

For example: 1) What is the subject.

i am a doctor.

you are a teacher.

2) How about the subject.

she is beautiful.

i am tired.

3) Where is the subject.

e,g: we are at home.

tom is in beijing.

Be adjective.

The infinitive is divided into two cases:

Wait. The infinitive after such adjectives indicates that the subject has this emotion to perform this action, as is the case with some of the example sentences you mentioned:

heiseagerto

please.He loves to please others

heisafraidtobe

fooled.

He was afraid that he would be fooled and deceived by others.

iamwilling

tohelp

you.He is willing (he goes) to help you.

heisgladto

helpus.

He was willing to help us.

heiskindto

helpus.

He was kind (he went) to help us.

In the above example sentences, the logical subjects of the infinitive are the subjects of the sentence.

Predicative adjectives denote the characteristic description of the subject, such as:

fool,easy,ready,slow,able,likely

Wait. The infinitive after such an adjective indicates that the subject has this characteristic to do something or to receive something, and in both cases, the infinitive has its own characteristics.

1) If it indicates that the subject has a certain characteristic to do something, the infinitive is a purely transitive verb or intransitive verb;

Such as the following example sentence:

heislikely

toaccept

ourhelp.

He may accept our help.

heisabletodoit.

He has the ability to do it.

heisslowto

react.

He acted unhurriedly and slowly.

In the above example sentences, the logical subject of the infinitive is also the subject of the sentence.

2) If it means that the subject has this characteristic to accept a certain behavior, the non-implicit chain formula often has two attributes, one is an intransitive verb and the other is an intransitive verb, while the infinitive following the adjective uses an intransitive verb. Such as the following example sentence:

heiseasyto

please.

(He's easy to please.)

heiseasyto

fool.He is easily deceived.

In the above example sentence, the subject of the sentence is the logical object of the infinitive.

Wherever the above situation is described, the subject is the perpetrator of the act with the capacity to act, infinitive.

It acts as an adjective complement (a reason adverbial). If the subject is not the case, but a noun that denotes a thing, then it does not fall into the above category.

thedinner

isready

toeat.

Dinner to be ready and ready to eat) in a sentence, the subject.

dinner

It is a thing that does not have the capacity to act, and the infinitive acts as a result adverbial, rather than an adjective complement (a reason adverbial).
