剖析：现在分词短语blocking out the sunlight在句子中作结果状语。
They worked day and night，finishing the work ahead of time.他们日夜工作，结果提前完成了工作。
考点：词组block out的含义是“挡住，遮住(光线和声音)；忘掉，抹去(不愉快的事)”。
如：The volcanic ash blocked out the sun.火山灰挡住了太阳。
An ugly building blocked out the view from the window.一座难看的大楼把窗外的景物遮住了。
I try to block out the unpleasant experience.我尽力去忘记那段不愉快的经历。
block off封锁，封闭Various barricades block off all the main streets of the city.各种路障封锁住了城里所有的主要道路。
block up阻塞，塞住，封住(孔，洞)The traffic is very heavy and has begun to block up the streets.交通量很大，已经开始把街道阻塞了。

如：What he wanted to see was an end to all the wars of the world.他想要看到的是世界上所有战争的结束。
2)主语从句位于句尾，使用it作形式主语。
如：It was right that the temple was rebuilt.庙被改建了，这很好。
在下列情况下，一般使用形式主语it，而将真正的主语从句放在后面：①谓语部分含有seem，appear，be (im)possible，be a pity，be a wonder，be likely等。
如：It appeared to scientists on the earth that the stars had moved.在地球上的科学家看来，这些星球已经移动了。
It's a wonder that you recognized me.你能认出我来，真是奇怪。
②在It is known...；It is said...；It is hoped...；It is believed...等惯用的被动结构中。
如：It is believed that before writing was developed，people in China used to keep records by putting a number of stones together.人们认为在文字发明之前，中国人靠把许多石头聚集在一起来作记录。
需要注意的是：当主语从句放在句尾而用形式主语时，形式主语只能用it，而不能使用this，that等代词。
考点二：主语从句的连接词可以分为以下三类：1)that，whether连接词that本身没有意义，不作句子成分，只表示从句的开始，位于句首时，that不能省略；whether含有“是否”的意思，whether可以加上“or not”，其语意不变。
