　　A. both dating

　　B. both of which have dated

　　C. and each has dated

　　D. and each one dating (A)

　　E. each one of which date

　　题目释义：A&P are the two oldest communities, both dating back at least 1000 years.

　　考点：

　　句子结构(grammatical construction) 习惯用语(idiom)

　　1. each 型独立主格,强调句尾名词,形式为:

　　句子 + 复数名词结尾, each +介词短语/形容词短语/-ed形式/-ing形式

　　2. 独立主格独立主格结构(Independent Genitive)有两部分组成，前一部份是名词或者代词，后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。前后两部分具有逻辑主谓关系。在句子中作状语，表示时间、原因、条件、伴随、目的、补充说明等。

　　有题的答案里面有despite having his Ving……，though having……，in spite of his Ving of， in spite of his 动作性名词 of。

　　前面是Having……，Scientists(不确定，反正是个人还是个物)have V.ed xxx。是考时态的一个。

　　部分倒装: 把谓语动词的一部分移至主语的前面.

　　全部倒装: 把整个谓语动词置于主语之前.

　　※单个的be动词只用全部倒装,但如果把表语,宾语,状语或宾语补足语等提到主语之前,则被称作前置.

　　一、全部倒装。

　　1.here, there, away, down, in, up, off, out, now, then, next, thus 等副词开头的句子里,谓语动词只有一个,主语不是代词。

　　Now comes your turn.

　　Out rushed the crowd.

　　※如果主语为代词,则主谓语序不变.

　　Here you are.

　　Out they rushed.

　　2. 介词短语作状语放句首。

　　那张桌子下睡着一只棕色的猫。

　　Under that table sleeps a brown cat.

　　North of the city lies a big paper mill.

　　3. 表语置于句首表强调,倒装结构为:表语+连系动词+主语

　　1)形容词+系动词+主语

　　出席会议的是怀特教授。
