Planet DannyPPT，第四部分内容：状语从句
1. 条件状语从句
当一个句子在复合句中用作状语时叫做状语从句。当从句表达“如果……”的意思时，叫做条件状语从句，我们通常使用连词if，unless来引导。
if引导的条件状语从句可以放在主句之前，但主从句之间常用逗号隔开。if引导的条件状语从句也可以放在主句之后，主从句之间无需用逗号隔开。
e.g. If he wants to go, please tell me.
Don’t cross the road if the traffic light is red.
unless是连词，意为“除非；如果不”，也可以引导条件状语从句，含有否定意义，相当于if ... not。
【注意】unless引导条件状语从句时，如果主句是一般将来时，从句用一般现在时表将来。
e.g. We’ll go to the concert unless it doesn’t rain.
2. 让步状语从句
让步状语从句由下列从属连词引导：
though（虽然），although（虽然），as（尽管），even if（即使），even though（即使），no matter …（不管）等。
e.g. Although it rained a lot, we enjoyed our holiday.
The house isn’t very nice. I like the garden though.
Even though I was really tired, I couldn’t sleep.
I’ll visit him this evening even if I can stay only a few minutes.
... ... ...
Planet DannyPPT，第五部分内容：Language Points
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的意思是“调转方向；转身”
e.g. I turned around / round and saw the boy climbing up the tree.
我转过身来，看到那个男孩正在往树上爬。
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。
unless是连词，意思是“除非，如果不”。
由unless引导的条件状语分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。
e.g. We won’t be able to reach the top of the mountain unless the weather changes(= if the weather doesn’t change).
如果天气不变化，我们就不能到达山顶。

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。

Planet DannyPPT，第三部分内容：教材解读
1.When they arrive,Danny is outside in the yard.
arrive为不及物动词,意为“到达,来到”,后接表地点的名词时,需使用介词in或at。in用于指较大的地点,at则指比较具体的小地点。arrive at/in与get to/reach同义。
2.He said that I could use his telescope.
本句含有that引导的宾语从句。无论主句是陈述句还是疑问句,宾语从句都应使用陈述语序。含宾语从句的复合句,主从句谓语动词的时态呼应包括以下三点:
(1)如果主句的谓语动词是一般现在时,宾语从句的谓语动词可根据需要,选用相应的时态。
(2)如果主句的谓语动词是一般过去时,宾语从句的谓语动词应用相应的过去时态。
(3)如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等,不管主句用什么时态,从句时态都用一般现在时。
3.Danny turns the telescope around and looks through it again.
turn around/round意为“调转方向,转身”。
4.Maybe Brian and I can join you after supper.
◆maybe为副词,意为“也许”;may是情态动词,也表示“也许”,但后面必须跟动词原形。
◆join为及物动词,意为“参加,加入”,其后可接人,也可接表示团体、组织、党派等的名词。join为非延续性动词,和表示一段时间的状语连用时应变为be in。
5.I don’t think you can find one unless you have a bigger telescope.
unless为连词,意为“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。unless通常相当于if…not…。
6.Actually,double the size of your house!
double可作名词或形容词,意为“两倍(的);双重(的)”,也可作动词,意为“使加倍”
