Đáp án D
Chúng ta dựa vào từ khóa của 2 vế câu: explain slowly và understand clearly. Nếu ta chọn phương án A. Liên từ as soon as sử dụng không phù hợp vì liên từ này dùng để thể hiện một hành động xảy ra liền ngay sau một hành động khác (ngay khi mà...). Hành động explain slowly không phải là hành động liền ngay sau understand clearly (không phù hợp về mặt logic và nghĩa của câu).
Nếu ta chọn đáp án C ta thấy động từ trong mệnh đề unless đang dùng sai thời với động từ của mệnh đề chính (hiện tại đơn - quá khứ đơn) → đáp án B không chính xác.
Chỉ còn lại 2 phương án B và D. Ta thấy hai phương án đang thể hiện mục đích của hành động explain slowly là để understand clearly. Khi thể hiện mục đích ta có thể sử dụng so that + mệnh đề. Động từ của câu đang chia ở quá khứ (explained) → động từ trong mệnh đề cũng sẽ chia quá khứ → đáp án D đúng Tạm dịch. Giáo sư Smith giảng bài một cách chậm rãi để học sinh của ông thật sự hiểu bài
❖ For review
Khi muốn thể hiện mục đích, chúng ta có thể sử dụng các cấu trúc sau:
- S + V + (not) to V/ in order (not) to V/ so as (not) to V: ai đó làm việc gì để làm gì/ không làm gì
- S1+ V1+ so that/ in order that S2+ V2 trong đó:
+ Nếu V1 ở hiện tại/ tương lai thì V2 = will/ can (not) V
+ Nếu V1 ở quá khứ thì V2 = would/ could (not) V
- With a view to (not) V-ing, S + V: để (không) làm gì, thì ai đó làm gìThey had a discussion about training not only the new employees but also giving them some challenges.

Mickey Mantle was one of the greatest baseball players of all time. He played for the New York Yankees in their years of glory. From the time Mantle began to play professionally in 1951 to his last year in 1968, baseball was the most popular game in the United States. For many people, Mantle symbolized the hope, prosperity, and confidence of America at that time.
Mantle was a fast and powerful player, a “switch-hitter” who could bat both right-handed and left-handed. He won game after game, one World Series championship after another, for his team. He was a wonderful athlete, but this alone cannot explain Americas fascination with him. Perhaps it was because he was a handsome, red-haired country boy, the son of a poor miner from Oklahoma. His career, from the lead mines of the West to the heights of success and fame, was a fairy-tale version of the American dream. Or perhaps it was because America always loves a “natural”: a person who wins without seeming to try, whose talent appears to come from an inner grace. That was Mickey Mantle.
But like many celebrities, Mickey Mantle had a private life that was full of problems. He played without complaint despite constant pain from injuries. He lived to fulfill his father’s dreams and drank to forget his father’s early death.
It was a terrible addiction that finally destroyed his body. It gave him cirrhosis of the liver and accelerated the advance of liver cancer. Even when Mickey Mantle had turned away from his old life and warned young people not to follow his example, the destructive process could not be stopped. Despite a liver transplant operation that had all those who loved and admired him hoping for a recovery, Mickey Mantle died of cancer at the age of 63.
