Explanation:

I underlined the mistakes in the sentences and then wrote the correct form in italics below.

From the first sentence to the third one, the tense used is present perfect. This tense is form by the auxiliary verb have ( I,you,we,they) or has (he, she, it) plus, a main verb in present participle if its irregular or past if its regular, e.g I've started to do my homework or I haven't written the letter yet.

In the last two sentences, the tense used is past simple. We can identify why present perfect isn't correct here because of the time references last week and yesterday. They reffer to an specific time in the past so the correct tense is past simple.

Explanation:She still needs to finish her homework.

She has known Mark for a long time.

He gave me a present last week.

The postman didn’t deliver the letter yesterday.

One of the euphemisms in "From Emperor to Citizen" is Puppet. It refers to Pu Yi who was called Emperor, but was actually controlled by the Japanese. Another euphemism is Forbidden City, because it wasn't forbidden for those who worked and lived there.
