3.the cork oak tree has (a layer ) of cork several inches (thickness) that can be stripped (every) ten (years).

1、同ARE并列，做DOPHINS的谓语。注意and unlike porpoises , (have ) well defined , breaklike snouts and conical (teeth).这是第二个并列句子。

2、答案是B吗？我觉得：MOST OF后要加THE，同时MOST OF前一般不加THE。

3、这里TEN YEARS作为一个整体概念讲，“每10年”

谢谢BRAVEMBA兄和dannylsy兄.
2的答案是B
另外1中HAVE并列的连词是AND吗?那么unlike porpoises 是做什么成分呢?

1、此句相当于
dolphins are sleek and (powerful) swimmers (that found) in all seas ，and [unlike porpoises , DOLPHINS (have ) well defined , breaklike snouts and conical (teeth).]

unlike porpoises 修饰主语 DOLOHINS，“不象。。。”

unlike porpoises 修饰主语 DOLOHINS，“不象。。。”

有些不明白,这里省略了主语,不需要连词连接两个句子吗?

S+V,V  这种句型是错误的对吗?

braveMBA

因为主语相同，有AND连接是可以省略主语的，那个AND是连接两个句子的，不是同前面句子的并列成分。但是，我认为这是TOEFL语法不够书面化的地方，一般情况下，书面表达中，如果连接两个句子，AND前应该有逗号。
