The Study of Living ThingsPPT, Part 4: Grammar

present perfect continuous tense

The present perfect continuous indicates that an action started at a certain time in the past and continues until now. The present perfect continuous tense is sometimes used to express frequent and repeated actions.

(1) Structure: have / has + been + V-ing

(2) Use with the time adverbials introduced by since or for; since is followed by the time when the action starts, and for is followed by a period of time; when asking questions about the time adverbials introduced by since or for, use how long.

(3) The negative form is formed by adding not after have / has, which can be abbreviated as haven’t / hasn’t.

(4) The general form of a question is to put have / has before the subject; for a positive answer, use “Yes, subject + have / has.”, and for a negative answer, use “No, subject + haven’t / hasn’t.”

e.g. a. -How long have you been drawing?

-I have been drawing for two hours.

b. -How long has Maria been playing the piano?

-She has been playing the piano since she was five years old.

c. They haven’t been working since last month.

d. -Has he been living here?

-Yes, he has. / No, he hasn’t.

attributive clause

Attributive clauses are clauses that play an attributive role in a compound sentence and modify nouns, pronouns or the entire main clause. The word modified by the attributive clause is called the antecedent. Relative words that introduce attributive clauses include relative pronouns (that, which, who, whom, whose, etc.) and relative adverbs (where, when, why).

The role of relative words in attributive clauses:

①Connect the main clause and the attributive clause;

② Refers to the antecedent;

③ Act as a certain component in the attributive clause.

(1) Relative pronouns that and which

In attributive clauses, the relative pronoun that can refer to both people and things, and which is generally used to refer to things.

When referring to things, the two are generally interchangeable, but which is often used as a guide in non-restrictive attributive clauses.

e.g. The old town has narrow streets and small houses that are built close to each other.

That evening, which I will tell you more about later, I ended up working very late.

(2) Relative pronouns who and whom

Who refers to people and is the nominative case. It serves as the subject in the attributive clause and can generally be replaced by that.

"Which" refers to a person, is an object in the attributive clause, and serves as the object in the attributive clause. In colloquial and informal writing, it can be replaced by who or that, or it can be omitted.
