Q

Many tourists in Europe are Europeans themselves, ____ others come largely from Asia and the Americas. A) while B) once C) since D) thus

老師這題為什麼選項是A?

A

在考場上，第一眼先觀察選項，我們發現 thus 是副詞，其他都可以當連接詞。因為空格之前、之後都是有主詞和動詞的子句，而且標點符號是「,」，所以應該選連接詞：

(a) Many tourists in Europe (主詞) are (動詞) Europeans themselves.

(b) Other tourists (主詞) come (動詞) largely from Asia and the Americas.

前後文的內容為「歐洲本地觀光客」與「來自亞洲和美洲的外地觀光客」的對比、差異，所以選 while，也可以用 whereas 來連接：

(a) Many tourists in Europe are Europeans themselves.

(b) Other tourists come largely from Asia and the Americas.

(a) + (b) = Many tourists in Europe are Europeans themselves, while/whereas others come largely from Asia and the Americas.

請參考牛津字典的第 3條定義。記得點開 Language Bank，可以看到「凸顯對比 highlighting differences」的各種表達方法。

其他選項：

(B) once 一旦 =as soon as

(C) since (1) 既然 =because (2) 自從(某時間)起：from an event in the past until a later past event, or until now

(D) thus 因此 =therefore; as a result

(D) thus 的意義如同連接詞 so，用在正式情境，如下列例句 1。請注意這兩句標點方式的差別：

1. Eating habits formed in childhood tend to continue into adult life. Thus, the best way to prevent heart disease among adults is to encourage healthy eating from an early age.

2. It was still painful(,) so I went to see a specialist.
