When they were served the ice cream 这是个什么时态的句子,是一般过去时吗
可一般过去时不是直接served就行了,为什么还要加上 were

When they were served the ice cream 意思是何时有人给他们提供了冰激 When they served the ice cream 意思是他们何时给别人提供冰激凌
前者是被动,被提供,也即有人提供
后者是主动,他们是提供者

When they were served the ice cream 这是个什么时态的句子,是一般过去时吗 What were you doing when the UFO arrived?是个什么时态的什么句子? when前后的时态可以全是一般过去时吗一个简单的英语问题they are like ice cream.这句话是错的吗?为什么一个句子里没有动词行吗我想知道 they()() ice cream 是she like ice cream还是she love ice cream?是they like cat还是they I like ice-cream.和I like ice-creams.哪个句子是对的? when后面的时态是不是只能是一般过去时,而不能用过去进行时.eg：When the students are sing They like hamburgers(ice-cream) ice-cream是可数的还是不可数? ice cream是可数名词吗 ice cream 是可数名词吗?
