Trang ơi sai rồi, không có "is being" ở câu 17, câu 13 từ nhận biết "for + tgian" -> hoàn thành, câu 19 chủ ngữ là "I", câu 20: câu này nhìn thoáng qua có vẻ phức tạp cơ mà vế đầu là quá khứ, vế sau có từ" but it is now -> hiện tại rồi, mà có từ yet -> hoàn thành, câu 23, không thể 1 vế là hiện tại mà vế còn lại là qk đâu, câu này là" một hành động đang xảy ra hành động khác chen vào", tiếp câu 24, ở đây will rain k bao giờ xảy ra, nó chỉ xảy ra 1 trong 2 thì là hiện tại tiếp diễn hàm ý tương lai và tương lai gần thôi, nhưng mà ở đây hành động xảy ra ngay lúc nói, nên chọn tdien hàm ý tlai. trên mạng có pbiet 2 thì này đấy.
