英文片語「as well as」vs.「as well」一字之差，但用法完全不同

「as well as」和「as well」是兩個很常見也常搞混的片語，僅一字之差，但用法各異 👉 as well as為對等連接詞，和 and 同義；as well 則為副詞片語，中文意思和 too, also 一樣為「也…」。

句型：A + as well as +B A和B

1. A 和 B 詞性或結構要相同，例如都是動詞、名詞、片語、子句等。

To find my phone, I looked under the couch as well as behind the TV.

為了找我的手機，我搜過沙發下面和電視後面。

2. 動詞單複數變化要與 A 一致。

Mrs. Lee as well as her husband drives to work.

李太太和她先生一樣開車上班。

The students as well as their teacher are going to the field trip.

學生和他們的老師都要參加校外教學。

！此用法文法上雖正確，但母語人士遇到此類情況多以 both ... and ... 敘述，因此這句更常用以下說法：

Both the students and their teachers are going to the field trip.

● as well as 也可以作介系詞使用，後面須接名詞或動名詞；這也就是為什麼我們會看到某些句子中 as well as 後方接的是 V-ing。

The teacher needs to prepare for the lessons as well as checking the students' homework.

除了檢查學生的作業之外，老師還得備課。

副詞片語 as well 表示「也…」的意思，語意相當於too、also。（3種「也是」的用法比較）
由於 as well 並非連接詞，故連接不同的語法單位時（片語、子句等），須與連接詞（and或but）搭配。

I like cooking new dishes and baking desserts as well.

= I like cooking new dishes and baking desserts, too.

= I like cooking new dishes and I also love baking desserts.

我喜歡烹煮新料理，也喜歡烘焙甜點。
