Planet DannyPPT，第四部分內(nèi)容：狀語從句
1. 條件狀語從句
當一個句子在復合句中用作狀語時叫做狀語從句。當從句表達“如果……”的意思時，叫做條件狀語從句，我們通常使用連詞if，unless來引導。
if引導的條件狀語從句可以放在主句之前，但主從句之間常用逗號隔開。if引導的條件狀語從句也可以放在主句之后，主從句之間無需用逗號隔開。
e.g. If he wants to go, please tell me.
Don’t cross the road if the traffic light is red.
unless是連詞，意為“除非；如果不”，也可以引導條件狀語從句，含有否定意義，相當于if ... not。
【注意】unless引導條件狀語從句時，如果主句是一般將來時，從句用一般現(xiàn)在時表將來。
e.g. We’ll go to the concert unless it doesn’t rain.
2. 讓步狀語從句
讓步狀語從句由下列從屬連詞引導：
though（雖然），although（雖然），as（盡管），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，第五部分內(nèi)容：Language Points
1. Danny turns the telescope around and looks through it again.
丹尼把望遠鏡掉過頭來，又從里面望去。
turn around / round的意思是“調(diào)轉(zhuǎn)方向；轉(zhuǎn)身”
e.g. I turned around / round and saw the boy climbing up the tree.
我轉(zhuǎn)過身來，看到那個男孩正在往樹上爬。
Why did they turn their desks around?
他們?yōu)槭裁窗褧婪欧戳耍?/p>
2. I don’t think you can find one unless you have a bigger telescope.
我認為你發(fā)現(xiàn)不了（星星），除非你有一個大一點的望遠鏡。
unless是連詞，意思是“除非，如果不”。
由unless引導的條件狀語分句既可以是真實條件，也可以是非真實條件。
作為真實條件分句，unless通常相當于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).
如果天氣不變化，我們就不能到達山頂。
