问题补充：

．The two brothers look so much that we can’t one from the other．

A. familiar, separate

B. familiar, tell

C. alike, differ

D. alike, distinguish

答案：

A. familiar, separate

B. familiar, tell

C. alike, differ

(答案→)D. alike, distinguish

解析：词义辨析。Familiar相似的，相近的，一般不用做表语。Alike相似的，相同的，一般用作表语。Separate分开，分离；tell告诉，识别；differ使……不同；distinguish区别，辨别。句意：这两个兄弟看起来是如此相似，以至于我们很难区分。故选D。
