IV. Supply the right form of each given word to complete each of the following sentences. (10 pts)

21. We have a lot of difficulties in learning English. (DIFFICULT) (sau a lot of thì cần có noun)

22. I felt very excited when I was a member of our school team. (EXCITE) (do chủ ngữ "I" là người bị tác động bởi sự việc "when I was a member of our school team" nên chia excite thành excited)

23. He speaks English fluently. (FLUENCY) ( sau speak english thì cần một trạng từ)

24. It is cloudy and raining today. (RAIN) (đứng sau tobe thì cần một V-ing(HTTD) hoặc Ved/V3 (câu bị động, trong khi đó "it" là chủ ngữ giả nên ko thể là câu bị động được, nên còn lại là HTTD)

25. Good preparation was the keys to the success of your interview. (sau tính từ thì cần một dnh từ)
