第一题这儿，over 2500miles作文extend的原因，或者说extend是over 2500miles的结果伴随状语，所以不能用and引导他们的关系，因此排除ABC，，D很容易排除，结果就选E，，实际上E的前半部分整个是插入语

第二题中自己好好琢磨吧，G中不用like举例，因为容易引起歧义，like有像的意思

第一题我怎么觉得，逗号前是一个句子，逗号后是一个句子，可没有连接词啊，第一句的谓语是built 第二句的谓语是was ??
第二题正确的里边用了like 举例啊？为什么还要选

第一题，built不是动词，是被动，built in the Americas整个修饰road system。。。
第二题，like表示对比，不是举例。。。
