第一道题应该选A，在题目出现强烈的程度副词，如first,only等，答案必须保持这些副词在句中的位置，否则句意会发生变化。

第二题我也曾有过疑问，Ms Peace帮我做了解答，
To Alex,

这道题一开始我也选C， 后来看了LZM的解释才豁然开朗。

这是LZM书上的解释：

C中，those指代主句的主语 the male and female blue winged warble, 而不能仅指代
the male and the female, 因为主句的主语不是 the male and female in the
blue-winged warbles 这种结构。 而当把those指代的内容代入unlike短语中，unlike短语
不知所云。

希望对你有帮助！

两个都是A.

第一题看意思，only位置不能变。
第二题，e，没必要用强调句。those 的指代是指the male and female bule warble。代回去意思不对了。

第一题选A，主要是因为ONLY 放在不同位置，将产生不同的含义，部分选项中，还有主谓一致的问题。
第二题选A，主要是看指代，E项在简介和重心转移上有问题

the first answer is a ,
the second is e, in a the verb are is not right.

第二题的。。。the male and female blue-winged warbler are very difficult to tell apart.
warbler应改成 warblers吧。
