答案

一、1. litter 2. leaves 3. either 4. respect

解析

【分析】
本题需结合句子语境、汉语提示或首字母,运用词汇知识和语法规则填写正确单词。先通读每个句子,理解句意,再根据提示和语法确定单词形式:第1题根据汉语“垃圾”填对应英文;第2题根据汉语“留下”和主语的人称、时态确定动词形式;第3题根据否定句语境和首字母填表“也”的词;第4题根据句意和首字母填表“尊重”的词。
【解析】
1. 句意:当校长看到垃圾时,他总是把它捡起来。“垃圾”的英文是litter,符合语境,故填litter。
2. 句意:我的英语老师通常把钥匙留在教室。“留下”是leave,主语My English teacher是第三人称单数,一般现在时谓语动词用第三人称单数形式,故填leaves。
3. 句意:我妹妹也不喜欢这家餐厅。否定句中表示“也”用either,符合语法规则,故填either。
4. 句意:作为学生,我们应该尊重我们的老师。“尊重”是respect,情态动词should后接动词原形,故填respect。
【答案】
一、1. litter 2. leaves 3. either 4. respect
【知识点】
单词拼写、一般现在时第三人称单数、否定句中“也”的用法
【点评】
本题考查基础词汇的运用,结合语境和语法规则填写单词,属于英语基础题型,需掌握常见词汇的拼写和基本用法。

答案

二、1. treat 2. quietly 3. relaxing 4. understands
5. person

解析

【分析】
本题考查方框内单词的适当形式填空,需先明确每个单词的词性与含义,再结合句子结构、句意判断所需词性,进而变形。具体思路:1. 观察句子结构,确定空格处的词性要求;2. 结合句意匹配对应单词;3. 根据语法规则(如动词形式、词性转换)变形单词。
【解析】
1. 空格前为助动词will,后接动词原形,结合句意“别担心费用——我会招待你”,故填treat。
2. 空格修饰动词talk,需用副词,quiet的副词形式为quietly,结合句意“小声说!奶奶在睡觉”,故填quietly。
3. 空格处需形容词,修饰“听音乐”这件事(物),用relaxing(relaxed修饰人),故填relaxing。
4. 主语no one为第三人称单数,一般现在时谓语动词用三单形式,understand的三单为understands,结合句意“问题太难没人理解”,故填understands。
5. 空格前为不定冠词a,后接可数名词单数,结合句意“他是很好的共事的人”,故填person。
【答案】
1. treat 2. quietly 3. relaxing 4. understands 5. person
【知识点】
动词变形、副词用法、形容词辨析
【点评】
本题为基础词汇变形题,考查单词在句子中的词性适配,需结合句意和语法规则变形,易混点为relaxing与relaxed的区别,整体难度较低,是常见的基础题型。

1. Alice gets up late today, so she
B
take the next bus.

A.must
B.has to
C.can
D.could

答案

1. B 根据take the next bus可知,她起晚了,不得不
乘下一班公共汽车,表示客观所迫,且主语是 she,用
has to。

解析

【分析】首先理解句子语境:Alice今天起晚了,因此她需要坐下一班公交,这是客观情况导致的“不得不”,需区分情态动词的用法差异:must表主观上的必须,have to表客观原因导致的不得不,再结合主语的人称和时态确定形式,最后逐一排除不符合语境的选项。
【解析】句子意为“Alice今天起晚了,所以她不得不坐下一班公共汽车”,此处是客观情况(起晚)造成的“必须”,需用have to;主语she是第三人称单数,一般现在时,故用has to。A选项must表主观义务,不符合;C选项can表能力,D选项could是can的过去式或委婉语气,均不符合语境,因此选B。
【答案】B
【知识点】情态动词用法
【点评】本题考查情态动词must与have to的用法区别,需结合语境判断是主观要求还是客观所迫,属于基础题型,侧重对情态动词核心用法的考查。
【难度系数】0.7
2. —
A
silent(沉默的), please! You are in the library.
— I'm sorry, madam.

A.Keep
B.To keep
C.Keeping
D.Kept

答案

2. A

解析

【分析】这道题考查祈使句的用法,需明确祈使句的结构特点,结合语境判断正确形式。
【解析】题干是图书馆场景下的祈使句,用于表达请求或命令,祈使句的结构为“动词原形+其他”。选项中只有A选项Keep是动词原形,符合祈使句开头的要求;B为不定式、C为动名词、D为过去式,均不符合祈使句结构,因此选A。
【答案】A
【知识点】祈使句用法
【点评】本题考查祈使句的基础结构,属于英语语法的核心基础考点,难度较低,适合巩固语法基础。
【难度系数】0.8
3. (2024·六安期末)— Must I take your books home now?
No
, you
needn't
. You can do it later.

A.Yes; must
B.No; mustn't
C.Yes; need
D.No; needn't

答案

3. D 根据“You can do it later.”可知,不需要现在就做,
must开头的一般疑问句,否定回答为“No,主语+
needn't.”。

解析

【分析】首先结合对话语境判断答语的态度,答句提到“You can do it later”,说明不需要现在做,因此需选否定回答。需牢记must开头的一般疑问句的回答规则:肯定回答用“Yes, 主语+must”,否定回答用“No, 主语+needn't”,mustn't表示“禁止”,不符合此处语境,据此排除错误选项。
【解析】根据答句“You can do it later”可知,此处为否定回答,先排除A、C选项(均为肯定回答);must开头的一般疑问句的否定回答不能用mustn't(表禁止),需用needn't,因此排除B选项,选D。
【答案】D
【知识点】情态动词must的用法;一般疑问句的答语
【点评】本题考查must引导的一般疑问句的答语,属于基础语法题,需准确掌握情态动词的固定答语规则,结合语境即可轻松作答。
【难度系数】0.3

C

D.think about

答案

4. C

解析

【分析】先理解句子语境:作为学生,上课不能使用手机,我们应该______学习。接下来逐一分析选项短语的含义,结合语境选出符合句意的选项。
【解析】各选项短语含义:A.hang out 闲逛;B.wait for 等待;C.focus on 专注于;D.think about 考虑。根据语境,上课不用手机的目的是专注学习,因此选C。
【答案】C
【知识点】动词短语辨析、语境理解
【点评】本题考查常见动词短语的词义辨析及语境运用,属于基础题型,难度适中,需要学生掌握短语意思并结合句子逻辑判断。
