答案与精析:
1.1) frightened 2) afraid 3) afraid 4) frightened
frightened 指突如其来的"震惊"。既可作表语,又可作定语。 afraid 多用于习惯地、经常地"惧怕"某些事,泛指一种恐惧心理,只能作表语,不能作定语。
2. 1) None 2) None 3) no one
none 与 no one 都可表示"没有人"。none可以用于人,也可以用于物,意思是"一个人也没有或没有任何东西"。 no one 只能用于人,意思是"谁也不,没有人",口语中常用,而且比none的意味强得多。none作主语时,它后面的谓语动词用单数或复数形式都可以,如强调整体情况,多用单数形式,如强调个体时,多用复数形式。no one 作主语时,谓语动词多用单数形式。回答how many 或how much问句用none; 回答who问句用no one 或nobody。
3. 1) true 2) real 3) true
real 表示"真的","真实的","名副其实的",指的是客观存在,并非想象和虚构的,它是与"无"相对而言的。true是指"真正的","真实的",强调与事实和实际情况相符。它是与"假"相对而言的。
4. 1) found 2) found 3) founded
found 既是不规则动词的find 的过去式和过去分词,本身又是一个动词原形,意思是"建立"。founded 为规则动词found 的过去式和过去分词。
5. 1) heard from 2) heard of 3)heard about / heard of
hear of 指听别人说起或提及某人或某事,即间接"听说"。hear about表示"听到......的详情",常与hear of 换用。hear from "收到......的来信或信息",介词宾语可以是人或地方。
6. 1) Thanks to 2) Thanks for 3) thanks to
thanks to意思是"多亏"、"由于"。这个短语多表达一种原因。作状语时,可位于句末,也可位于句首。thanks for是一个客套用语,意为"因......而感谢",这里thanks可改为thank you。
