考点8 考查either…or的搭配与用法
either…or…的意思是“要么……要么……”“或者……或者……”，用于肯定其中的一者，而否定其中的另一者。如：
You must either go at once or wait till tomorrow. 你要么马上走，要么等到明天。
You can either come with me now or walk home. 你要么现在跟我来，要么步行回家。
通常应连接两个相同性质的句子成分，但有时后一成分可能省略与前一成分相同的词。若连接两个成分作主语，其谓语通常与靠近的主语保持一致。如：
You can either have tea or coffee. 你喝茶也行，喝咖啡也行。
Either you or I am wrong. 不是你错，就是我错。
三、易错陷阱
陷阱1 误用because…so…结构
有的同学由于用汉语的“因为……所以”的影响而将误用because…so…这一错误结构。由于because为从属连用，用以引导原因状语从句，而so为并列连词，用于连词两个简单句使之成为并列句，它们是两个性质完全不同的连词，习惯上不能搭配使用。如：
明天我得工作一整天，所以我没有时间去买东西。
误：Because I’m going to be working all day tomorrow, so I won’t have time to shop.
正：I’m going to be working all day tomorrow, so I won’t have time to shop.
正：Because I’m going to be working all day tomorrow, I won’t have time to shop.(www.hxen.com)
陷阱2 误用although…but…结构
与上面的情况相似，有的同学由于用汉语的“虽然……但是”的影响而将误用although…but…或though…but…这类错误结构。由于although / though为从属连用，用以引导让步状语从句，而but为并列连词，用于连词两个简单句使之成为并列句，它们是两个性质完全不同的连词，习惯上不能搭配使用。如：
虽然这辆自行车很贵，她还是决定买了。
误：Although the bicycle was expensive, but she decided to buy it.
正：Although the bicycle was expensive, she decided to buy it.
正：The bicycle was expensive, but she decided to buy it.
