(一.)现在进行时与过去进行时的区别:

肯定句:The robots are making a car now. 这些机器人正在生产小汽车。
否定句:We are not studying on the Internet. 我们没有在互联网上学习。
疑问句:Is the teacher looking up the word in the dictionary?这个老师正在词典中查这个词吗?
特殊疑问句:Who am I talking to?我在和谁谈话? 
2.过去进行时表示过去某一时间,正在发生或正在做的事情。基本结构was(were)+现在分词。
肯定句:When he came in,I was writing a letter.当他进来时,我在写一封信。
否定句:They weren’t watching TV while she was reading. 她读书时,他们没在看电视。
疑问句:Was the UFO flying to us at 8 last night ?昨晚8点UFO向我们飞来了吗?
特殊疑问句:What were you drinking while we were sleeping?我们睡觉时,你们在喝什么?
进行时态往往用在时间状语从句中,常与when,while等连词搭配。
(二.)be sure结构表示肯定和不肯定。be sure一般用来表示肯定,be not sure(whether/if)表示不肯定。
be sure后面可以跟不定式和宾语从句。跟不定式一般译为“一定……”,跟宾语从句,译为“确信……”。
如:
We are sure to repair the TV well. 我们一定修好这台电视机。
I’m sure you can finish your work. 我确信你能完成你的工作。
Are you sure whether(if)he switched the computer on? 你确信他打开还是没有打开电脑?

Could you tell me something about robots?
Can robots take the place of humans?
Are you sure there are UFOs?
Yes,I’m sure.
No,I’m sure whether/if there are UFOs.
