Answer 1

1 He looked troubled yesterday (прошедшее - он выглядел встревоженным вчера)
2 She has never done this work (Present Perfect - она никогда не делала подобной работы - речь о жизненном опыте)
3 A boy is reading a book now (Present Progressive - Мальчик читает книгу в данный момент)

Answer 2

1) He looked troubled yesterday.

The correct form of the verb in this sentence is "looked." We use the past simple tense (looked) to describe actions or states that happened and ended in the past. In this case, the subject "He" appeared troubled at some point in the past, and this state of being troubled is now over.

2) She has done this work.

The correct form of the verb in this sentence is "has done." We use the present perfect tense (has done) to talk about actions or states that started in the past and have a connection to the present. In this case, the action of doing the work started in the past and is still relevant to the present moment.

3) A boy is reading a book now.

The correct form of the verb in this sentence is "is reading." We use the present continuous tense (is reading) to describe actions happening at the moment of speaking. In this case, the boy is currently engaged in the activity of reading a book.

Note: The options provided for each sentence are a), b), and c). The correct choices are indicated above.
