英语语法讲解Before all the different types of Barbie dolls for sale now,there was just a single Barbie.
①types of/kinds of+名词，固定搭配，表示“各种…”，前面可接各种形容词，如all,some,different, several,many等等。
②for sale 固定搭配，“待售（即将出售）”（注意和on sale区分，“上市，正在出售”）
③before引导时间状语从句，表示主句发生于从句之前。
The three-dimensional model for Barbie was a German doll — a joke gift for adults described as havingthe appearance of "a woman who sold sex".
①who sold sex为定语从句修饰a woman
②gift后的介词必为for
③as在此作介词，表示“作为…”，故其后接名词性动词ing形式
④ described as……一堆是动词过去分词构成的短语作定语，用来修饰前面的a joke gift，意为“这个可笑的礼物被描述为……”，改成定语从句变为：a gift which was described as…
⑤ 从属关系A of B of C of D of ……，翻译成“…的D的C的B的A”，其核心词是A
Mattel refashioned the doll into a decent, all-American —although with an exaggerated breast size — version and named it after Barbara, who was then a teenager.
①refashion A into B "把A改制成B"
②although with an exaggerated breast size这句话为插入语，主要作用是解释前面的all-American这个词范围有些夸张，起解释说明作用。插入语可插在句子的任意位置，其插入并不影响主句的结构，也就是说，插入语可以看做是打酱油的，把它拿掉，主句就清晰了——Mattel refashioned the doll into a decent, all-American version，and named it.
③name A after B “以B的名字称号来命名A”
④ who was then a teenager为定语，修饰Barbara
