【句子】

Although mockingbirds superbly mimic the songs and calls of many birds, they can nonetheless be quickly identified as mockingbirds by certain aural clues.
盡管模仿鳥學(xué)很多種鳥的鳴叫聲惟妙惟肖，但人類還是能夠依其聲音上的線索很快識別它們。

【解析】

gh的用法

1)表示“雖然”時，不要根據(jù)漢語習(xí)慣，在后面使用連詞 but, 不過有時它可與 yet, still, nevertheless 等副詞連用

他雖然年紀(jì)很大了，但還很強壯。

正：Although he is very old, (yet) he is quite strong.

誤：Although he is very old, but he is quite strong.

但是在一定的上下文中，類似下面的 although 與 but 連用的句子是可能的 (注意 but 引出的句子在 although 從句之前) 。如：

But Ididn’t know that then, although I learned it later.
但我當(dāng)時的確不知道此事，盡管后來還是知道了。

2)有時用于主句之后，起補充說明的作用，相當(dāng)于 however, but

He is poor-- although he is well contented.
他很窮，然而卻能知足常樂。

3)若主從句主語相同，且從句謂語含有動詞be, 可將從句主語和動詞 be 省略

Although (he is) quite young, he knows a lot.
雖然很年輕，但他很懂事了。

4)不能用于 as though (好像)，even though (即使) 等習(xí)語中代替 although, 也不用于讓步狀語的倒裝形式中。
