⑴Which date from about 1250 BC. 是一个非限制性定语从句，在关系代词之前通常用逗号把从句和主句分开，同限定性定语从句相比，非限定性定语从句限定性不强，只是对先行词作些补充说明，翻译时通常分别译成两个句子。例如：
Yesterday I met Li Pin, who seemed to be very busy. 昨天我遇到李平了，他好象很忙。
Prefessor Wang, whom I met this morning, asked you to ring him up.今天早晨，我遇到王教授了，他要你给他打电话。
⑵date from/back to是一个动词短语，表示“（从某时期起）就已存在”（to have existed since the date of building or origin），可译作“从某时期开始（有）”，“可追溯到”或“是……时代开始有的”等。例如：
This castle dates from the 14th century. 这座城堡建于14世纪。
My interest in stamp collecting dates back to my schooldays. 我对集邮产生的兴趣是从学生时代就开始了。
This town dates back to the Roman times. 这座城镇的历史可以追溯到罗马时期。
⒑If was carved in the rock and had on the outside four large stone figures, each of which was 20 metres high. 这座寺庙凿雕在岩石中，外边有四尊大型石雕像，每个高20米。
each of which was 20 metres high是一个非常限制性定语从句，each of which=each of the four figures, 这种定语从句是用“名词（或代词）+介词+关系代词”来引导的。类似的句子如下：
On her desk are two books, both of which are about Chinese history. 她的书桌上有两本书，这两本书都是讲述中国历史的。
Yesterday he bought two books, one of which is about American history. 昨天，他买了两本书，其中一本是讲述美国历史的。
They live in a house, the door of which opens to the north.
There are about three hundred teachers in our school, most of whom are women. 我们学校大约有300名教师，他们中多数是女教师。
China has hundreds of islands, the largest of which is Taiwan. 中国有数百个岛屿，其中最大的是台湾。
⒒In all, 1700 workers and 200 other people worked on the project. 总共有1700名工人和200名其它工作人员参加了这项工程。
in all是一个介词词组，作“总共”，“总计”解。相当于in total = altogerther。例如：
That will cost you 500 dollars in all(in total). 你总共要花500美元。
The cost of the project amounts in total to 25,000 US dollars. 这项工程的费用总计25,000美元。
I spent three hundred yuan in all on these books. 我总共花了300元买这些书。
⒓Today you can either fly to Abu Simbel or take a boat from across the lake. 今天你可以乘飞机去阿布辛波古庙，或者从湖的对岸乘小船去。
from across the lake意思是“从湖的对岸”，相当于from the other side of the lake. From后还可跟一个介语短语。例如：
I saw them coming towards me from across the street. 我看见他们从对面朝我走过来。
They saw a yellow dog run out from behind the door. 他们看见一只大黄狗从门后跑了出来。
A white cat ran out from under the bed. 一只白猫从床底下跑了出来。
