點滴英語天天學第111期:分手了!(語法詳解2)

今天，我們繼續第三課《分手了！》的學習。從今天開始，我們來咬文嚼字，分析這一課中對話每一個句子的語法現象。

1. She busted him when she walked into their bedroom and found him with some tramp.

解析1：這是一個含有時間狀語從句的符合句。主句是“she busted him”，從句是“when she walked into their bedroom and found him with some tramp”，when是時間副詞，表示時間。

解析2：“She walked into their bedroom and found him with some tramp.”中的“and”是連詞，在這裏表示“結果”，用中文說則是：結果是，就。例如：

Miss another class and you will fail in the exam. 在缺一次課，你考試就會不及格。

解析3：“She walked into their bedroom and found him with some tramp.”中的“found him with some tramp”這個結構是find+賓語+介詞短語，表示“發現某人做某事”。這個介詞短語“with some tramp”是做賓語的補足語，補充說明某人在做什麼事情。

2. Jane must have been so upset.

解析：這個句子使用了虛擬語氣。“must have been so upset”是“must have done something”這個結構，它用於表示對過去發生的事情的非常肯定的猜測。在對話中，Jennifer非常肯定地猜想到Jane因爲發現Mike與外人有染的事情而心煩。再如：

It must have been a valuable experience. 那準是有價值的所見所聞了。

Something must have gone amiss, so he's not here to meet us. 準是出了什和差錯，他沒來這裏接我們。

解析2：upset是形容詞，表示“因爲某事而煩心”，介詞用“at”。例如：

He was upset at not being invited. 人家沒邀請他，他很不痛快。
