As teacher I am required to plan all my lessons and assessment. I can't take any risks.

hi dear friend i m looking forward and be glad to get your comments

The word "take" is trick. Anyone can take a risk or take public transportation. Planning does take thought but not the word "take". Take your time and learn the many ways to use "take". I am glad that you "took a chance" and asked your question. I will take my time thinking up an answer.
