Сложносочиненные предложения/согласование времен

  • Здравствуйте. Помогите, пожалуйста, себя перепроверить. Это сложносочиненные предложения и согласования времен можно не придерживаться? Спасибо.
    1) Dave bought a pair of glasses because he can't see very well.
    2) Johm bought a new car last year, but he hasn't bought one this year.

  • 1) Dave bought a pair of glasses because he can't see very well.---...because he could not see very well.---Сложноподчиненное предложение.

    2) Johm bought a new car last year, but he hasn't bought one this year.---Правильно. Сложносочиненное предложение.

  • Спасибо большое. Прикольно, первое предложение из программы "неправильные глаголы с примерами". Зацарапало слух, но подумала, что они же не могут ошибаться....значит я. Еще раз спасибо.

  • Ни он, ни они не ошибаются. Оба варианта возможны в разных ситуациях.

  • Извините, Вера, можно ли попросить Вас в двух словах пояснить из каких соображений возможен тот или иной вариант. Или как мне найти где об этом прочитать. (это в грамматике случай какой? Если я хочу понять в каком случае как, мне искать что?) Спасибо.
