急！！明天要用了！！

Answer 1

does 一般现在时
一、 一般现在时：
1.概念：经常、反复发生的动作或行为及现在的某种状况。
2.时间状语： always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays,
3.否定形式：am/is/are+not;此时态的谓语动词若为行为动词，则在其前加don't,如主语为第三人称单数，则用doesn't，同时还原行为动词。
4.一般疑问句：把be动词放于句首；用助动词do提问，如主语为第三人称单数，则用does，同时，还原行为动词。
