Задача 1
Условие (кратко)
Записать краткие формы шести сочетаний с глаголом to be (He is, She is not, We are, I am, They are not, You are).
Решение
В краткой форме буквы глагола заменяются апострофом:
- is → 's: He is → He's;
- is not → isn't: She is not → She isn't (или She's not);
- are → 're: We are → We're, You are → You're;
- am → 'm: I am → I'm;
- are not → aren't: They are not → They aren't (или They're not).
Ответ
1 He's, 2 She isn't, 3 We're, 4 I'm, 5 They aren't, 6 You're
Почему так
Краткие формы to be — 'm, 's, 're, а с отрицанием — isn't и aren't (am not сокращается только как I'm not).
