| explain | 解释： 主句比较简单，而后面跟着的由and 连接的两个表示让步的条件状语从句就相对复杂。第一个从句是用一个修饰主语的定语从句that equip those plants to enter into a symbiosis with nitrogen fixers把主谓隔开；第二个从句则动用了插入语once they are found 把主谓隔开。 |

| tips | |
| explain | 解释： 主语的后置修饰成分既多又长，造成谓语离主语的距离很远；而且主语和谓语之间又被插入语when they considered women at all 分开，可谓雪上加霜。不过这个插入语也不是乱加上去的，作者其实在暗示这些人很少考虑到西部的妇女。句末的fell under T's spell中的spell原来指咒语、魔法，后来被引申为强烈的影响力和吸引力的意思，在此指a strong compelling influence or attraction。 |

| tips | |
| explain | 解释： 主语the requirement后面带着一个长长的修饰主语的同位语；由于requirement的同位语中要求使用虚拟语气，所以其中的系动词成了原型（should be省略了should）。如此之长的修饰成分过后，谓语can be met与主语的关系已经很难理清了。从by开始的状语的结构更为复杂：修饰techniques的后置的定语［derived from studying the reaction s (of tissue cultures to biomaterials or derived from studying short-term implants)］实际上是由or 所连接的两个derive from；但是这两个derive from又都极其难懂：第一个derive from中还套了另外一个固定搭配the reaction s (of tissue cultures to biomaterials)；第二个derive from则干脆把derive给省略了。此外，上本句的专有名词奇多，这使得阅读的难度非常高。 |
