The subject is generally a noun, a pronoun; A predicate is a verb; There are two types of inverted inverted and fully inverted, in which the beginning of the sentence is the place, the time phrase or word is completely inverted, and the others are partially inverted! This is the experience summed up by the teacher! Please adopt!!

what：

The subject clause caused by the relative pronoun form what is often translated as "so......”

For example: what you said is wrong. The subject clause of what can be introduced can generally be placed at the beginning of the sentence.

that: that guides the subject clause to be the most widely used, but it is rarely actually placed at the beginning of the sentence, because the subject is too long and will appear top-heavy. However, sometimes the beginning of the sentence is also placed for emphasis or when the predicate is long.

Common structures:

be + adjective + clause, like it is strange that i ......be + noun + clause, as in it is a wonder that......Verb (+ object or adverbial) + clause like it remind me that......

Passive voice + clause of a verb, as in the event was reported that amazed me

The second sentence in the box is a complement to do something, and because something is an object, it is an object complement throughout the whole process!

2.in the box is the place adverbial. Not a complement.

be common in (at......In is a preposition, in is a preposition, a noun must be used after a preposition, and the verb ing is a gerund, which is a noun.

This sentence is seen as an inverted something in the box is thereSomething to add a note to **.

Hello, the first question: Because the preposition in adds the object, only the gerund doing can be the object, and now the participle doing cannot be the object.

Question 2: This question is a bit controversial. Interpret it as you want it to:

There be structure, there is only a structure word, not a subject, and the real subject is "something".

Then the phrase is: something is there.

Subject + Dependent Verb + Table Structure is a category of subject + verb + subject complement.

So "in the box" is a complement to something here, and it is a subject complement.

Hope it helps.

ps: subject + verb + subject complement, this structure is not often spoken in middle school, often the subject + verb + predicate is more, but the latter belongs to the former.

Pick B, obviously, to this morning is the action of the past, and the until guide time adverbial, which means that I have been working until seven o'clock this morning, so use the past continuous tense, not the present perfect tense.

The upstairs explanation is wrong, if the present perfect continuous tense is used, it means that the past action has continued until the present, and there is a possibility of continuing into the future, while the title means that it has continued to the past and has stopped.

Choose A and emphasize the impact on the present!

a, followed by until, means that it has been working until 7 o'clock this morning, and the continuous action should be in the present perfect tense.
