二、用方框中所给词语的适当形式填空,每词仅用一次
strength fact per slim pleasant
1. The
fact
is that 70% of our classmates enjoy outdoor activities.
2. After three months of exercise, Lucy looks much

than before.
3. Our school library allows borrowing two books
per
student.

more pleasant
than in the city.
5. Teamwork can increase our
strength
to solve difficult problems.

答案

1. fact 2. slimmer 3. per
4. more pleasant 5. strength

解析

【分析】
解题思路:先明确方框内词汇:strength(力量,名词)、fact(事实,名词)、per(每,介词)、slim(苗条的,形容词)、pleasant(宜人的,形容词),且每词仅用一次。再逐句分析句子结构与语境,结合语法(如比较级、词性要求)选择词汇的适当形式:1. 缺主语需名词,对应fact;2. 有than需形容词比较级,对应slim的比较级slimmer;3. 表“每”对应per;4. 有than需多音节形容词比较级,对应more pleasant;5. 缺名词对应strength。
【解析】
1. 句意为“事实是70%的同学喜欢户外活动”,此处需名词作主语,方框中fact(事实)符合,故填fact。
2. 句中出现than,需用形容词比较级,slim的比较级为slimmer,意为“更苗条的”,符合语境,故填slimmer。
3. 句意为“我们学校图书馆允许每个学生借两本书”,per表示“每”,符合语义,故填per。
4. 句中出现than,需用形容词比较级,pleasant是多音节形容词,比较级为more pleasant,意为“更宜人的”,符合语境,故填more pleasant。
5. 句意为“团队合作能增加我们解决难题的力量”,此处需名词,strength(力量)符合,故填strength。
【答案】
1. fact 2. slimmer 3. per 4. more pleasant 5. strength
【知识点】
形容词比较级、名词词义辨析、词汇适当形式填空

解析

【分析】
首先观察例句结构:一般疑问句用be动词(is)引导,结构为“Is + 主语 + 比较级 + than + 另一主语?”,回答后“as...as”中间用原级。对于动词类,需用助动词does引导一般疑问句,副词的比较级对应变化,“as...as”中间用副词原级。再结合括号内的词逐个构造:
1. 小题1:主语Ella,形容词outgoing(多音节,比较级more outgoing),比较对象you,故构造be动词开头的疑问句,as后用形容词原级;
2. 小题2:主语Ella,动词dance,副词well(比较级better),比较对象Sally,故用助动词does开头的疑问句,as后用副词原级;
3. 小题3:主语Emma,动词短语get up,副词early(比较级earlier),比较对象Jim,用助动词does开头的疑问句,as后用副词原级;
4. 小题4:主语Emma,动词短语work hard,副词hard(比较级harder),比较对象Tom,用助动词does开头的疑问句,as后用副词原级。
【解析】
1. 小题1:根据括号内词,outgoing是多音节形容词,比较级为more outgoing,be动词is引导一般疑问句,故Q为“Is Ella more outgoing than you?”;“as...as”中间用形容词原级outgoing,故填outgoing。
2. 小题2:dance是动词,主语Ella为第三人称单数,助动词用does;well是副词,比较级为better,故Q为“Does Ella dance better than Sally?”;“as...as”中间用副词原级well,故填well。
3. 小题3:get up是动词短语,主语Emma为第三人称单数,助动词用does;early是副词,比较级为earlier,故Q为“Does Emma get up earlier than Jim?”;“as...as”中间用副词原级early,故填early。
4. 小题4:work hard是动词短语,主语Emma为第三人称单数,助动词用does;hard是副词,比较级为harder,故Q为“Does Emma work harder than Tom?”;“as...as”中间用副词原级hard,故填hard。
【答案】
1. Q: Is Ella more outgoing than you?
A: No, she isn't. She is as outgoing as me.
2. Q: Does Ella dance better than Sally?
A: No, she doesn't. She dances as well as Sally.
3. Q: Does Emma get up earlier than Jim?
A: No, I don't think so. I think Emma gets up as early as Jim.
4. Q: Does Emma work harder than Tom?
A: No, she doesn't. She works as hard as Tom.
【知识点】
形容词比较级,副词比较级,as...as结构
【点评】
本题考查初中英语基础语法:形容词和副词的比较级变化、as...as结构的用法,以及一般疑问句中be动词/助动词的选择,是日常学习中需掌握的核心考点,侧重基础应用能力。
