新概念英语第二册Lesson19_21学习笔记

新概念英语第二册Lesson19~21学习笔记新概念英语第二册Lesson19学习笔记1 The play may begin at any moment.剧马上就要开演了。

在这句话中，说话人指的并不是一种确信不移的事实，而是可能发生的事情，因此用may+动词的结构。

It may have begun already.可能已经开始了。

这句话也是表示可能发生的事情，因为表示可能已经发生的事情，所以用may+动词完成时的结构。

2 hurry to+spl.匆忙赶往某地例句：We hurried to the airport.我们匆忙赶往机场。

3 What a pity!真遗憾!这是What+a/an/the+名词的感叹句形式。

以what开头的感叹句还有以下几种。

①What+名词例句：What fun!真开心!②What+(a/an)+形容词+名词例句：What a said story!真是个凄凉的故事啊!③What+ a/an+形容词+名词(+主语)+谓语例句：What a delicious dinner you made!你做了真丰盛的晚餐啊!④What+名词+主语+谓语例句：What happy girls they are.那些女生好幸福啊!4 exclaim [动词] 惊叫，呼喊相当于scream，cry out，指因疼痛、惊奇、愤怒等突然喊叫。

例句：She screamed when seeing the devastating car accident.当她目击这场惨烈的车祸时忍不住惊叫起来。

词语扩展：exclamation n. 呼喊，惊叫，叹词，感叹语exclamation mark 感叹号，叹号5 Could I ...please?在这句里，could代替了can，这是比较委婉地提出请求的用法。

在时间上和can没有区别。

6 might as well...还是……好，不妨与may as well意思相同，只不过前者更委婉。

新概念英语第二册第二十一课课后习题答案详解

新概念英语第二册第二十一课课后习题答案详解新概念英语第二册第二十一课课后习题答案详解Lesson 211. c根据课文第3-4行Last year, however, it came into use, 只有c. came into use recently 比较接近课文的实际内容，而其他3个选择都不符课文内容。

2. d根据课文第8行…but I am determined to stay here, 只有d. has refused to leave his house 与课文内容相符，其他3个选择都与事实不符。

3. c只有选c. can hear 才能使这个句子同前一句Passing planes can be heard night and day 的含义相同，只是语态不同。

而其他3个选择a. can heard, b. can to hear, d. can be heard 都不符合语法，在意思上都讲不通。

4. d 只有d. possible 才能使句子同前一句It couldn't be used then 意思最接近。

a. able (能)需要人作主语，本句的主语是it 形式主语;b. allowed(允许)不符合题目的意思， c. impossible(不可能的)与句子意思相反。

5. a 前面句子Over a hundred people must have been driven away 中的must 表示说话人的一种主观推测。

b. I’m sure(我确信) 语气比较肯定，不表示推测;c. Certain(肯定的)是形容词，缺主语和谓语，不符合语法和题目意思。

; d. Of course(当然) 表示“肯定”的意思，也不够准确; 只有a. I think(我想，我认为) 表示推测，所以应该选a.6. c 只有c. are some left 才能使这个句子比较接近前一句I am one of the few people left,因为few(少数几个)同some(一些)意思比较接近, a. are none left(一个没剩)不等于the . is one left(剩下一个)也不等于the few;d. are a lot left(剩下很多)与the few 意思相差悬殊.所以选c.7. b 这是一个疑问句，需要主谓倒置语序。
