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 dont 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ifnot。例如：We wont be able to reach the top of the mountain unless the weather changes.(=if the weather doesnt 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：Wed like a double room. 我们想要一个双人间。4. Well, its worth a try, even if I dont find a planet.好吧，这值得一试，即使我找不到一颗行星。 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。Thestampis notworthcollecting.这张邮票不值得收藏。 even if 从属连词，表示假设情况，意思是“即使.”，引导让步状语从句。 e.g. 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。四、当堂检测. 根据汉语提示完成句子。1.
