Помогите пожалуйста с переводом на английский в сослагательном наклонении.

1) It's strange that he should behave like that.
2) It's amazing that she shouldn't understand it.
3) The workers demanded that the wages should be paid in time.
4) The captain ordered that the ship should be offloaded at once.
5) He speaks English as if he were an Englishmen.
6) It's desirable that the agreement should be signed as soon as possible.
В пятом предложении должно быть именно так: as if he were, это не ошибка.
В третьем и четвёртом предложении should можно опустить и оставить только be paid и be offloaded, но такое употребление сослагательного наклонения характерно только для американского варианта, в британском оно считается устаревшим.
В первом, втором и шестом should опускать нельзя.
В предыдущих переводах нет НИ ОДНОГО правильного употребления сослагательного наклонения.
