We listened eagerly, for he brought news of our families. 我們急切地聽著，因為他帶來了我們家人的消息。

3. due to 向來是形容詞，作介詞不是傳統用法，而作容詞的due to只可用在be (或is、was等be的變體)之後。

His failure was due to his laziness. 他的失敗是因為他的懶惰。 “Due to his laziness (adjectival phrase)” is modifying “his failure.” 「Due to his laziness（形容詞片語）」用來修飾「his failure」。

4. because of 是複合介詞，其後接名詞、代詞、動名詞、what 從句等。

I feel cold now because of the freezing AC.

我現在感覺冷是因為冷氣開得太冷。

“because of the freezing AC (adverbial prepositional phrase)” is modifying/explaining “I feel cold now.”

「because of the freezing AC（副詞介系詞片語）」在這裡用來修飾「I feel cold now」。 在現代英語中，「due to n.」經常與「because of n.」可互換使用。然而，一些語法學家會建議你在正式寫作中不要這樣做。 資料出處: http://words.journalism.ku.edu/because.html

5. since 多為陳述性的事實，相當於「既然」。

Since it’s raining, we should stay indoors. 因為在下雨，我們應該待在室內。

Since he missed the deadline, he will have to wait until next year to apply again. 因為他錯過了截止日期，他必須等到明年才能再次申請。
