Как это устроено
1. Глаголы восприятия — see, hear, watch, notice, feel, observe — работают по схеме:
\[ \text{see/hear/watch} + \text{объект} + \begin{cases} \text{bare infinitive (без to)} \\ \text{V-ing} \end{cases} \]
- без to — действие воспринято целиком, как законченный факт: I heard someone knock at the door (услышал стук — и всё);
- V-ing — действие воспринято в процессе, оно длилось: She heard the baby crying all night long (слышала, как плач продолжался).
2. Глаголы принуждения и разрешения make, let — только без to: make the students rewrite, let me stay out late.
3. Глаголы просьбы, ожидания, желания ask, expect, would like, need — только с to: expect her son to become, ask me to open, would like you to meet, need him to post.
Почему в Ex. 2 везде -ing
- for an hour, all night long — прямое указание на длительность, значит процесс;
- when she came home — действие уже шло в этот момент;
- one by one — постепенное развёртывание процесса;
- в задании прямо сказано «Use Ving where necessary», а во всех восьми предложениях контекст допускает и требует именно процесса.
Обратите внимание на № 9 и № 13: там два глагола и одно подлежащее, поэтому форма должна быть одинаковой — crossing … entering, climbing … getting.
Проверка
Подставьте к каждому предложению вопрос «действие целиком или в процессе?»:
- We watched the children playing for an hour → процесс → V-ing ✔
- The teacher made the students rewrite → принуждение → без to ✔
- She asked me to open → просьба → с to ✔
Если в № 11–16 из Ex. 1 учитель ждёт «процессную» форму — допустимы варианты standing, touching, knocking; в этом упражнении отрабатывается именно отсутствие to, поэтому базовый ответ — без to.
