Các trường hợp dùng "wish" thì cũng tương tự, chia làm 3 loại, cách dùng như bạn NHH đã nói ở trên và có 1 số biến thể tương tự nhé.
Đối với trường hợp "if" được sử dụng như một liên từ dùng để bắt đầu một mệnh đề phụ trạng ngữ chỉ điều kiện về thời gian, lúc này "if = when". Vậy "if" và "when" khác nhau thế nào? 
- WHEN: được dùng khi diễn tả một điều gì đó chắc chắn xảy ra.
Ex. I am going to do some shopping today. When I go shopping, I'll buy you some coffee.
- IF: được dùng khi diễn tả một điều không chắc chắn (có thể hoặc không thể) xảy ra trong tương lai.
Ex. I may go shopping today. If I go shopping, I'll buy you some coffee.
Lưu ý:   Động từ chính trong mệnh đề phụ trạng ngữ bắt đầu bằng "when" hoặc "if" luôn ở thì present simple mặc dù hành động sẽ xảy ra trong tương lai.
Ex. When/If he arrives tomorrow, I'll tell him about it
