saw后面的两个动词都加ing?I saw some people sitting at the back of the classroom listening/listened to the teacher. 选择哪个? I like后面加动词还是动词的ING形式? see和saw后面加动词是不是都是ing i like 后面的动词要不要加ing I love to 后面的动词可以加ing吗? I am的后面加动词原形还是ing急 动词后面的动词加ing吗? when I saw him,I could not help (laugh)为什么答案上填的是laughinghelp后面不是不能加动词的ING形式吗 动词后面的动词要ing 如,I like playing video games.里面里like（动词）后面要动词ing,是不是所有的动词后面的动词?并说明理由.那为什么like后面的动词要加ing? 动词后面加ing的词都有哪些? 什么词后面的动词加ing? to后面的动词加ing吗? 代词后面的动词要加ing? 关于英语现在进行时的疑问如果一个现在进行时有两个动词或多个动词,是都把他们加ing呢,还是只在第一个动词后面加ing呢?是I am learning to swim these days.还是I am learning to swimming these days. 求解 like后面的动词如果是个都加ing?假如like后面是2个动词如 run and swim是不是都加ing?还是第一个加第二个不加?Why？还有问个下，I like play computer games怎么该一般疑问句？ like 后面加动词ing形式,and 的后面第二个动词要加ing吗? 英语动词的问题I will go draw up the paperwork now.在这里draw不应该是ing的形式吗?两个动词连在一起后面的动词不应该加ing吗? I'd like后面跟动词是不是加ing
