答案與精析：

1．1) frightened 2) afraid 3) afraid 4) frightened

frightened 指突如其來的"震驚"。既可作表語，又可作定語。 afraid 多用于習慣地、經常地"懼怕"某些事，泛指一種恐懼心理，只能作表語，不能作定語。

2． 1） None 2） None 3） no one

none 與 no one 都可表示"沒有人"。none可以用于人，也可以用于物，意思是"一個人也沒有或沒有任何東西"。 no one 只能用于人，意思是"誰也不，沒有人"，口語中常用，而且比none的意味強得多。none作主語時，它后面的謂語動詞用單數或復數形式都可以，如強調整體情況，多用單數形式，如強調個體時，多用復數形式。no one 作主語時，謂語動詞多用單數形式。回答how many 或how much問句用none; 回答who問句用no one 或nobody。

3. 1) true 2) real 3) true

real 表示"真的"，"真實的"，"名副其實的"，指的是客觀存在，并非想象和虛構的，它是與"無"相對而言的。true是指"真正的"，"真實的"，強調與事實和實際情況相符。它是與"假"相對而言的。

4． 1） found 2） found 3） founded

found 既是不規則動詞的find 的過去式和過去分詞，本身又是一個動詞原形，意思是"建立"。founded 為規則動詞found 的過去式和過去分詞。

5. 1) heard from 2) heard of 3)heard about / heard of

hear of 指聽別人說起或提及某人或某事，即間接"聽說"。hear about表示"聽到......的詳情"，常與hear of 換用。hear from "收到......的來信或信息"，介詞賓語可以是人或地方。

6. 1) Thanks to 2) Thanks for 3) thanks to

thanks to意思是"多虧"、"由于"。這個短語多表達一種原因。作狀語時，可位于句末，也可位于句首。thanks for是一個客套用語，意為"因......而感謝"，這里thanks可改為thank you。
