2 难点练习答案

3多项选择题答案
1. 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 couldnt 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 few.
b. 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.
