He was surprised when I saw him . (我见到他的时候，他感到很吃惊。)be surprised to do 做.令人吃惊 吃惊地去做. eg, I am surprised to see you here.be surprised at sth. 对感到吃惊 eg, I was surprised at his words.surprising 令人吃惊的,常用来修饰物或主语是物.eg, It is surprising news for me. to ones surprise 令人惊讶地是 To my surprise, he passed the exam easily.5) Isnt that amazing! 那是不是太令人惊奇了！此句为否定疑问句结构，其用法为：（1）否定疑问句表示感叹，相当于陈述句，但比陈述句语气更强烈，感情更丰富。 Arent the flowers beautiful! 这些花太美了！（2）否定疑问句也可以表示询问，意为“难道不？”其答语在形式上与一般疑问句的答语一样，肯定回答用yes,否定回答用no。但翻译成汉语时，yes要译成“不”，no要译成“是的”。Cant you speak English?难道你不会说英语吗？Yes, I can./No, I cant.不，我会。/是的，我不会。6). You can imagine how strange it was! 你能想象它有多么奇怪！本句中的感叹句how strange it was是宾语从句，作动词imagine的宾语。how strange it was为感叹句，句式结构为“How+形容词/副词+主语+谓语！”。How hard she studies!她学习多么刻苦啊！【拓展】感叹句的另一种形式是由what引导的，其结构为“What+ a/an+形容词+名词（+主语+谓语）！”。What a nice day it is!多好的一天啊！7).amazing 意为“惊人的，了不起的”，大多表示褒义，用于修饰物，说明“物”。Eg：What an amazing film!amazed意为“吃惊的，惊异的的”，用于修饰人物，说明“人”，作表语时，用于“be amazed at/by”结构中。I was amazed at/by his calmness. 我对他的镇定感到吃惊。【注】类似的还有：interested/interesting；surprised/surprising；annoyed/annoying【预习自测】：一用所给词的适当形式填空1.What an _(amaze) sight!2.I often see Mrs. Green_(water) flowers in her garden.3.This is an _(amaze) story.4.While I_(sing) an English song, he _(come) in.5.Please tell me your _( experience) while in China.6.We _(listen) to the radio at 7:00 yesterday evening.7.
