請益文法 - 自學

Is it true that Bill,who eats nothing but vegetables,is practicing yoga

in his office while he works?



解答寫錯誤的地方是 is practicing

請問要如何修正?

是practices嗎


If business is slow,our sales reps don't get bonuses,which is lowering

morale and doesn't help productivity.

請問 is lowering是不是要改成lows?

謝謝
