急问：大作文中有必要存在“让步段"么

If you are skillful enough to clarify what are you going to say, that's fine.

If you have enough time to write whole bunch of words, which would probably confuse the raters, then you shouldn't! You'd better go back to check your spelling, as well as grammar, mistakes.

If you want to get a score on the test, you need to keep you essay as simple as it can ever be. Always remember, simple is the best!

One sentence is enough.

And you don't need to focus on it too much, or you'd confuse the rater, which is likely for you to get a lower score.
