?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。如:他雖然年紀(jì)很大了,但還很強(qiáng)壯。正:Although he is very old, (yet) he is quite strong. 正: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:。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(bǔ)充說明的作用,相當(dāng)于 however, but。如:He is poor-- although he is well contented. 他很窮,然而卻能知足常樂。
The price increase will obviously be unpopular, although it’s unlikely to reduce demand. 價格升高顯然會不受人歡迎,然而這不大可能會降低人們的需求。

?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。如:省略。如:Although (he is) quite young, he knows a lot. 雖然很年輕,但他很懂事了。
In any case, she was very lovablealthough not at all tidy. 不管怎么講,她還是很可愛的,盡管一點(diǎn)也不愛干凈。

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