三、交流展示

Language Notes: 1. Danny turns the telescope around and looks through it again. 丹尼把望远镜掉过头来,又从里面望去。

turn around/round 调转方向;转身

e.g. Why did they turn their desks around?

他们为什么把书桌放反了? 2. I don’t

think you can find one unless you have a bigger telescope. 我认为你发现不了星星,除非你有一个大一点的望远镜。

本句中unless 是连词,意思是“除非,如果不”;由unless引导的条件状语从句既可以是真实条件,也可以是非真实条件。作为真实条件分句,unless通常相当于if……not。例如: We won’t

be able to reach the top of the

mountain unless the weather changes. (=if the weather doesn’t

change) 3. Actually, double the size of your house! 实际上,是你房子大小的两倍。

double作动词,意为“使加倍,翻倍”。如: The number of the houses here may double in

5 years. 五年内这里的房屋数量可能会翻倍。

double作形容词,意为“双倍的、两倍的、两用的”,在句中作定语或表语。如: We’d

like a double room. 我们想要一个双人间。

4. Well, it’s

worth a try, even if I don’t

find a planet.

好吧,这值得一试,即使我找不到一颗行星。

①

worth意思是“相当……价值;值得”;常用be worth +n./doing形式。

e.g. The book is worth 20 dollars. 这本书值20美元。

The stamp is not worth collecting. 这张邮票不值得收藏。

②even

if 从属连词,表示假设情况,意思是“即使…….”,引导让步状语从句。

eg:He was still working hard at English, even if he was seriously ill. 即使他病得很重,他依然努力学英语。
