三.语法学习

（一.）现在进行时与过去进行时的区别：

１.现在进行时表示现在正在发生或正在做的事情，基本结构be＋现在分词。如：

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？

四.交际用语：学习用英语谈论现代科技。

1 Could you tell me something about robots   ?   2 Can robots take the place of humans?

3  Are you sure there are UFOs?  4  Yes,I’m sure.5  No,I’m sure whether/if there are UFOs.
