BBC紀(jì)錄片：冰雪世界 第一集

1 Over one third of our planet is frozen， and yet the icy worlds of the Actic and Antarctic are as alien to most of us as the surface. 我們的星球有三分之一被冰雪覆蓋,然而北冰洋和南極洲的冰雪世界對大多數(shù)人來說簡直是外星地表。

2 They are places of superlatives, from ice caps that hold nearly 80% of our planet's fresh water to frozen forests that encircle the entire globe.這里充滿了各種極致,從冰帽里貯藏著地球上80%的淡水到環(huán)繞星球一周的冰凍森林。

3 These are places that feed our imaginations,places that seem to be borrowed from fairy tales. 這些地方能引起我們的想象，宛如從童話中借來的一般。

4 They are dominated and shaped by the ice, both by its coming and by its going. 它們由冰雪主宰和塑造，無論是因其前進(jìn)還是后退.

5 This is our planet's last true wilderness, and one that is changing just as we're beginning to understand it.這是我們星球最后的真正荒原。而且在我們剛開始了解它的時(shí)候它正在變化。

語法：that is changing 現(xiàn)在進(jìn)行時(shí)

6 In this series, we'll be travelling to all parts of these lonely lands both north and south to witness its wonders perhaps for the last time and to discover some extraordinary examples of survival against all the odds as can be found anywhere on the planet. 在本系列中，我們會(huì)前往這些遍及地球南北的孤寂之地。也許是最后一次見證那里的奇觀。并且要探索一些地球上在最為惡劣嚴(yán)酷的環(huán)境下生存的非凡代表。

詞匯：against the odds 迎難而上

語法：注意將來進(jìn)行時(shí)，將來一個(gè)比較明確的時(shí)間區(qū)間，如：

I'll be talking about animals this class.我們這節(jié)課會(huì)談?wù)剟?dòng)物。（ 你這節(jié)課不會(huì)上一輩子吧，就是比如從7點(diǎn)上到8點(diǎn)的時(shí)間區(qū)間）

 I'll be dining out with my girlfriend tonight. 我今晚會(huì)和女朋友一起進(jìn)餐。（今天晚上也不會(huì)是一輩子吧，大概就是那么幾個(gè)小時(shí)區(qū)間）

比較兩個(gè)時(shí)態(tài)：

I'll work hard. 我會(huì)好好努力工作的。（心里想著，哼，為啥要工作，有可能說的是80歲的時(shí)候）

I'll be working hard this weekend. 我這周末會(huì)好好努力工作的。（這就不一樣了，有區(qū)間呀，我這周末一定好好工作，因?yàn)橐苍S不好好工作就會(huì)被炒了?。?/p>

這就是為啥be going to 比will決心要強(qiáng)，因?yàn)榍罢邚?qiáng)調(diào)了將來進(jìn)行呀~哈哈哈

如果我要做演講肯定用Today I'll be talking about..., 而不是I'll talk about...，因?yàn)榍罢邭鈭鰞擅装搜絶
