         หนังสือเล่มนี้มีเพียง 8 หน้า(รวมหน้าปก), มี test วัดความสามารถด้านคำศัพท์ ให้ทำ 100 ข้อ, มีเฉลยอยู่ท้ายเล่ม 
คำชี้แจงในการทำ
        A sentence followed by a key word and a second sentence which has a gap in it. You have to use the key word to complete the second sentence so that it means the same as the first sentence.
Exam Tip!
       Each question is marked in two halves and it's perfectly possible to get one whole point in the exam just for getting a single word correctly, even if you don't know the other words to put in the gap. So you should always give every question a try.
