30分也叫重金.
一. 一般现在时:表示现一阶段经常,反复发生的动作或者存在的状态.常常和经常(ofen)通常(usually)有时(sometimes)等表示时间频度的副词连用.动词多数使用原型,当主语为单数第三人称时,则使用三单形式,如:做(does)去(goes).
What do you usually do on the weekend?
I usually do my homework .
What does he do on the weekend
He does his homework..
二. 现在进行时:表示说话人说话时动作正在进行.动词使用be加现在分词.如做(doing),去(going ).
What are you doing
I am doing my homework.
What is he doing
He is doing his homework..
三. 一般将来时:表示将要发生的动作,常常和将来的时间连用如:明天tomorrow,下周next week,明年next year等.动词原形前面加上be going to.
What are you going to do next weekend
I am going to take a trip next weekend.
What is he going to do next weekend
He is going to play the piano.
四. 一般过去时:表示过去发生的动作或者存在的状态.动词使用过去式,如做(did)去(went).
What did you do last weekend
I played football.
What did Mike do last weekend
He did his homework..
动词词型变化:
1. 三单:多加上(s)或(es)
Play—plays do –does go—goes study—studies watch—watches wash—washes
2. 现在分词:多数加上(ing)
Play-- playing do –doing run –running take---taking
3. 过去式:多加(ed)
Play –played dance –danced study –studied
不规则动词的过去式:
Do ---did go –went read –read swim –swam sing –sang take—took eat—ate have—had buy—bought see—saw leave –left get—got
举一反三
