Извини, что не все, но я не знаю какие ошибки там, где я не ответила

1) When I comed, my mother was cooking dinner.
2) Who did play yesterday?
3) There is nobody in the room.
4) I have never heard this song
5) There are some water in the cup или There are a little water in the cup. тут смотря в чем ошибка. В первом варианте ошибка в том, что вода не может быть во множественном числе. Во втором случае просто с неисчислимыми существительными в небольшом количестве лучше употреблять a little. Но я советую первый вариант.
6) He is going to watch TV
7) I worked hard last month
8) Did you really cook it for me?
9) She was playing the piano from 2 till 3 yesterday/
10) The film have already begun, when they arrived at the cinema
11) I was doing my homework? while he was watching TV
12) If you freeze water, it will turn to ice
13) He didn't get many presents on his birthday.
