一、認識英文句子的結構

(一) 對等連接詞：
主要有and, or, but, so。可將兩個單句連接起來，使其變成複句。
1：句 + (,) 對等連接詞(and/or/but/so) + 句.
The young couple sang and (the young couple) danced all night.
那對年輕夫婦通宵唱歌跳舞。
Get up earlier, or you'll be late.
早點起床，否則你會遲到。
It is hot in summer in Kaohsiung, but it is not cold in winter.
高雄夏天熱，但冬天不冷。
He was sick, so he didn't go to school yesterday.
他生病了，所以昨天沒有上學。

【注意】
★以上四個為最常見的對等連接詞，其他偶爾會看到的還有：
1. 句, for＋句.
→[for為對等連接詞，表原因]
You should stop smoking, for it is not good for your health.
你應該要戒菸，因為那對你的健康無益。
2. 句, yet/while/whereas＋句.
→[yet/while/whereas為對等連接詞，表「然而，但是」]
She didn't know me, yet she helped me.
= She didn't know me, while she helped me.
= She didn't know me, whereas she helped me.
她不認識我，但是卻幫了我。
