Planet DannyPPT,第二部分内容:课堂互动探究
1 He looks through the telescope. 他通过望远镜看。
[探究] look through是动词短语,意为“_____________”, through是介词,后面接名词、代词作宾语。
The boy is looking through the window. 那个男孩正在通过窗户看。
[拓展] look through还可译为“浏览,快速看”。
2 I don't think you can find one unless you have a bigger telescope.
我认为你不能找到一颗(行星),除非你有一架更大的望远镜。
[探究] (1)unless用作________词,相当于“if…not”。由unless引导的________状语从句中,谓语动词只能是肯定式,表示强烈的否定条件;它也遵循“主将从现”的原则,即主句是一般将来时态,从句用一般现在时态。
(2)本句中宾语从句在think 之后,且主句的主语又是第________人称,在否定从句时,句子的否定体现在________句中,这种现象叫否定前移。遵循“否定前移”的其他常用单词还有suppose, believe, expect等。
3 Well, it's worth a try, even if I don't find a planet.
嗯,值得一试,即使我找不到行星。
[探究] (1)worth作________词,意为“值得……的”。“be worth+n.”意为“值……”;be (well) worth doing sth.意为“(很)值得做某事”。
This book is worth reading. 这本书值得一看。
The film is well worth seeing. 这部电影很值得看。
(2)even if 引导________状语从句,意为“即使;纵然”。
[拓展] although, though, even if和even though都表示“虽然,即使,尽管”,且都可以引导让步状语从句。although和though语气较弱,even if和even though 带有强调意味且语气更强。
Although it was very cold, he went out without an overcoat.
虽然天很冷,但他没有穿大衣就出去了。
Even though it was raining, she walked to work.
即使下着雨,她也走着去上班了。
