I challenge you to say the alphabet backwards -- Z, Y, X, W, V, U, T, S, R, Q, P, O, N, M, L, K, J, I, H, G, F, E, D, C, G, A. Like that.

我挑战大家倒着念字母表——Z, Y, X, W, V, U, T, S, R, Q, P, O, N, M, L, K, J, I, H, G, F, E, D, C, G, A，像这样。

Try saying the alphabet backwards as fast as you can. Z, Y, X, W, V, U, T, S, R, Q, P, O, N, M, L, K, J, I, H, G, F, E, D, C, B, A, like that.

把字母表倒过来说，Z、 Y、X、W、V、U、T、S、R、Q、P、O、N、M、L、K、J、I、H、G、F、E、D、C、B、A，就这样。
