THE NIGHT THE EARTH DIDN’T SLEEP
There were deep cracks that appeared in the well walls.
Eleven kilometers directly below the city, one of the most deadly earthquakes of the 20th century had begun, a quake that even caused damage more than 150 kilometers away in Beijing.
Two thirds of the people who lived there were dead or injured.
The number of people who were killed or badly injured in the quake was more than 400,000.
Soon after the quakes, the army sent 150,000 soldiers to Tangshan to dig out those who were trapped and to bury the dead.
Workers built shelters for survivors whose homes had been destroyed.

关系代词的用法

That house _______ roof is brown is mine.
房顶是棕色的那个房子是我的。
指人，the person’s
指物，the roof of the house
whose
whose
关系代词只能用that的情况
She has something that you can borrow.
(1)先行词为不定代词all, everything, nothing, much, something, anything, little等,只能用that。
I’ve read all the books that are not mine.
This is the first tree that he has planted.
This is the very book that I want to read.
(2)先行词被特定缠，that抢先把位占。
(3)先行词前序高级，使用that必无疑。
all, every, no, some, any, little, much, the only, the very, the last
(4)先行词为人和物, that来当顶梁柱。
The film star and her film that you have just talked about are well-known.
(5)先行词在特疑中, 避免重复that冲。
Who is the man that is standing there
Which is the T-shirt that fits me most
关系代词只能用which的情况
This is the news on which we are focusing.
(1)关系代词前有介词时（介词+which）
(2)非限制性定语从句 (, +which)
We should do exercies everyday, which can keep us healthy.
1. Mr. Chen is one of these teachers who _______ (teach) you English.
陈老师是教你英语的这些老师之一。说明陈老师和其他老师是并列关系，即都是教你英语的老师。
2. Mr. Chen is the only one of these teachers who __________ (teach) you English.
陈老师是这些老师中唯一一个教你英语的老师。说明陈老师的唯一性，即这些老师中只有陈老师教你英语。
teach
teaches
一般来说定语从句紧接在先行词后面，如句一先行词是these teachers，而不是前面的one。因此定语从句的动词和these teachers保持一致。
而一旦给one of前面加上the only，那么先行词就变成the only one了，因为定冠词具有确定性，only具有唯一性。所以定语从句的谓语动词和one保持一致用单数。
