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。
