By the way 是一個(gè)簡(jiǎn)單而非常實(shí)用的英文句子，例如你跟別人聊天，談到一些尷尬話題，此時(shí)你可說(shuō)：By the way，接著說(shuō)別的事情避開尷尬場(chǎng)面。By the way通常用在談話時(shí)轉(zhuǎn)到別的話題的一個(gè)連接詞，可以解作‘除此之外’和‘順便一提’的意思，有時(shí)候會(huì)簡(jiǎn)寫成btw。 另外，在書信上我們常看見(jiàn)P.S.的英文字母在信的末端出現(xiàn)，它的全寫是Post script，Post是拉丁文 After(在之后)的意思，在正文之后的東西就是附注。

對(duì)話

A：Check, please.

B：That's 34 dollars. Thank you.

A：You're welcome. By the way, may I have your number, Candy?

B：Sorry, I'm afraid not.

A：Oh, I'm sorry, don't get me wrong. I just want the restaurant's number to make a reservation.

B：I understand but we're closing down next Monday.

甲：請(qǐng)結(jié)賬。

乙：34元，謝謝。

甲：不用客氣。除此之外，肯蒂，可否給我你的電話號(hào)碼?

乙：對(duì)不起，不行。

甲：噢，對(duì)不起，不要誤會(huì)。我只是想要餐廳的電話號(hào)碼以便訂位。

乙：我明白，但我們于下周一結(jié)束營(yíng)業(yè)。

By the way三字，一般譯做‘順便說(shuō)說(shuō)’，表示要轉(zhuǎn)入新話題或提出忽然想到的事。譬如說(shuō)，你和朋友在談西方音樂(lè)，忽然想到中樂(lè)，你就可以問(wèn)：By the way, do you like Chinese music as well?(說(shuō)到音樂(lè)，你也喜歡中樂(lè)么?)。

By the way的另一說(shuō)法，是incidentally。形容詞(adjective) incidental即‘附帶的’，例如：There are quite a few problems incidental to relocating to a foreign country(遷居國(guó)外，附帶的問(wèn)題不少)。Incidentally等于‘附帶談?wù)?rsquo;，例如：I didn't know he was one of your best friends.... Incidentally, do you know his sister?(我一向不知道他是你的好朋友....那你認(rèn)識(shí)他的妹妹嗎?)Incidentally除了用于口頭，也常見(jiàn)于文字;by the way則少見(jiàn)于文字，多用于口頭。

By the way也作by the by或by the bye，例如：By the by, he'll be here tomorrow(順便一提，他明天會(huì)來(lái)這里)。By the by切勿和by and by混淆：by and by是‘不久’的意思，例如：He said he would be here by and by.(他說(shuō)不久就會(huì)來(lái)到)。

By the way也不可和by way of混淆：by way of是‘當(dāng)作’或‘經(jīng)由’的意思，例如：(1) Tom gave him some money by way of thanks for helping with the luggage.(湯姆給他一些錢，算是答謝他幫忙提行李)。 (2) He went to Shanghai by way of Hong Kong.(他經(jīng)由香港到上海)。
