Day25语法专练【解析】
答案：C解析：根据Both the air and the water are badly polluted.”(空气和水都受到了严重污
染)可知，现在家乡的环境不如以前好了。“nots0as.”表示“不如.”，符合语境。A选项“as
good as'”表示“和..一样好；B选项much better than”表示“比.好得多”；D选项more worse
than”表述错误，worse已经是比较级，前面不能用more修饰。所以选C。
2.
答案：A解析：“in the past40 years'”是现在完成时的标志词，所以第一空用现在完成时has
changed'”;第二空，肯定句中用“as..as.”表示“和..一样”，否定句中用“not so.…as.”或not
as.…as,”,本句是肯定句，所以用“as sweet as'”。B、C选项第一空时态错误，D选项第二空用
于否定句，不符合语境。所以选A。
3.
答案：A解析：“nots0.as”中间用形容词或副词的原级，表示“不如”，所以这里用good”
B选项better”是比较级；C选项best和D选项the best'”是最高级，均不符合语境。所以选A。
4.
答案：D解析：“as long as'”表示“只要”；'as well as'”表示“也；和..一样好”；“as good as'”
表示“和..一样好；“as much as'”表示“和.一样多；尽可能多地”。根据“all that you get is
what you want'”(你得到的都是你想要的)可知，这里表达“你可以尽可能多地给予你喜欢的”，
所以用“as much as'”。所以选D。
5.答案：A解析：“nots0.…s.”是固定结构，意为“不如”，用于同级比较，表示前者在某方
面不如后者，所以“My bedroom isn't so large as Li Peng's.”表示“我的卧室不如李鹏的卧室大”。
B选项中than”用于比较级，而small”是原级，搭配错误；C选项“asas.”中间应该用原级，
不能用“larger'”;D选项the largest'”是最高级，这里不是三者或三者以上的比较，不符合语境。
6.
答案：A解析：“asas”中间用形容词或副词的原级，表示“和..一样，所以这里用
“important'”。B选项“more important'”是比较级；C选项“most important'”和D选项“the most
important'”是最高级，均不符合语境。所以选A。
7.
答案：B解析：表示倍数的常用结构有“倍数+as+形容词或副词的原级+as”,所以This
building is about twice as tall as that one.”表示“这座楼大约是那座楼的两倍高。A选项中“two
times'表述错误，一般用twice表示两倍；C选项two time”表述错误，且“so..as..”一般用于否
定句，这里是肯定句；D选项“second使用错误，不符合倍数表达结构。
8.答案：B解析：“as.…as”中间用形容词或副词的原级，表示“和..一样”，肯定句中用
asas.”,否定句中用“nots0.…as”或not as.…as.”。本句是肯定句，所以用'as good as'”,表示
“电子书和纸质书一样好”。C选项“as better as'”表述错误；D选项“so good as'”用于否定句。所以
选B。
9.
答案：A解析：“work”是动词，要用副词修饰，“good”是形容词，其副词是“well”。asas.”
中间用原级，所以用“wel”。B选项best”是最高级；C选项better'”是比较级；D选项“good'是
形容词，不符合语境。所以选A。
10。答案：B解析：'as long as'”表示“只要”；“as good as'”表示“和.一样好”；“as well as'”表示“也；
和..一样好”，还可以表示“和”，连接两个并列成分；“ass0onas表示一.…就.”。根据
"China's excellent culture is
treasure'可知，这里表达中国优秀的文化就像财富一样”，“as
good as'”符合语境。所以选B。
