解析

【分析】
本题为英语用所给单词适当形式填空的题型,需结合句子中的时间标志判断时态,再根据空格在句中的成分确定词性变化。具体思路:1. 观察句子的时间状语(如always、last class、usually、yesterday等)确定时态;2. 若为动词,根据主语单复数、时态变化变形;若修饰动词,用副词;若表示职业,转换为对应的名词。
【解析】
1. 第一空:句中时间状语为always,表经常性动作,用一般现在时,主语the teacher是第三人称单数,动词smile变第三人称单数形式smiles;第二空时间状语为last class,表过去的动作,用一般过去时的否定式,结构为didn't + 动词原形,故填didn't smile。
2. 空格处修饰动词run,需用副词,形容词quick的副词形式为quickly。
3. 不定冠词an后接可数名词单数,art对应的表示“艺术家”的名词为artist。
4. 第一空时间状语为usually,表经常性动作,用一般现在时,主语she是第三人称单数,动词take变第三人称单数形式takes;第二空时间状语为yesterday,表过去的动作,用一般过去时,动词drive的过去式为drove。
5. 第一空时间状语为often,表经常性动作,用一般现在时,主语she是第三人称单数,动词go变第三人称单数形式goes;第二空时间状语为yesterday,表过去的动作,用一般过去时,动词swim的过去式为swam。
【答案】
1. smiles; didn't smile 2. quickly 3. artist 4. takes; drove 5. goes; swam
【知识点】
一般现在时、一般过去时、词性转换

to school on foot.

A.Are; drive; go
B.Do; drive; went
C.Were; drive; went
D.Did; drive; went

答案

D

解析

【分析】
这道题考查一般过去时的用法,解题思路是先找到时间标志词“when you were a boy”,确定对话描述的是过去的事情,需用一般过去时。再结合一般过去时的一般疑问句构成规则、动词形式变化来逐一分析选项。
【解析】
1. 时间状语“when you were a boy”表明动作发生在过去,需用一般过去时。
2. 第一空:一般过去时的一般疑问句中,若句中有实义动词drive,需借助助动词Did,故第一空填Did。
3. 第二空:助动词Did后要接动词原形,故填drive。
4. 第三空:答句描述过去的动作,需用go的过去式went,故填went。
综上,对应选项D。

D

2. — What are you doing now?
— I'm watching a film on TV. The film
started
about an hour ago.

A.starts
B.started
C.start
D.will start

答案

B 根据about an hour ago可知,描述过去的事情,时态为一般过去时。

解析

【分析】首先观察句子中的时间状语“about an hour ago”,它是一般过去时的典型标志,说明动作发生在过去,需使用一般过去时的动词形式;再逐一分析选项的时态,选出符合要求的答案。
【解析】根据句中时间状语“about an hour ago(大约一小时前)”可知,句子描述过去发生的动作,应使用一般过去时。选项A“starts”是一般现在时第三人称单数形式,选项C“start”是动词原形,选项D“will start”是一般将来时,均不符合;选项B“started”是start的过去式,符合一般过去时的要求,因此选B。
【答案】B
【知识点】一般过去时、动词过去式

3. When I was in primary school, Miss Wang
taught
me English.

A.taught
B.teaches
C.teach
D.teaching

答案

A 根据was可知本句是一般过去时,动词用过去式。

解析

【分析】首先观察句子中的时间状语"When I was in primary school",这表示过去的时间,由此可判断句子需使用一般过去时,谓语动词要采用过去式形式。接着分析各选项的动词形式,选出符合一般过去时要求的选项。
【解析】句子的时间状语"When I was in primary school"明确了动作发生在过去,因此句子时态为一般过去时,谓语动词需用过去式。选项A.taught是动词teach的过去式,符合一般过去时的谓语要求;选项B.teaches是一般现在时第三人称单数形式,选项C.teach是动词原形,选项D.teaching是现在分词,均不符合一般过去时的谓语结构,故正确答案为A。
【答案】A
【知识点】一般过去时、动词过去式
【点评】本题考查一般过去时的基本用法,核心是通过时间状语判断时态,进而选择正确的动词形式,属于英语时态的基础题型,难度较低。

A.goes; takes
B.went; took
C.went; takes
D.goes; took

答案

D 经常做某事用一般现在时,今天早晨做了某事用一般过去时。

解析

【分析】
首先观察句子中的时间标志词:前半句有“often”(经常),表示经常性、习惯性的动作,需用一般现在时;后半句有“this morning”(今天早晨),表示过去的时间,需用一般过去时。再结合动词的形式变化,即可选出正确答案。
【解析】
1. 前半句:根据时间状语“often”,确定时态为一般现在时,主语Tom是第三人称单数,谓语动词go要使用第三人称单数形式goes;
2. 后半句:根据时间状语“this morning”,确定时态为一般过去时,动词take要使用过去式took;
综上,符合要求的选项为D。

5. — Did you
buy
a book yesterday?
— No, but I
bought
a schoolbag.

A.buy; bought
B.bought; buy
C.buy; buy
D.bought; bought

答案

A 助动词did之后通常用动词原形,买书包是昨天的事,用过去式。

解析

【分析】
本题考查一般过去时的动词形式用法。解题思路:1. 问句中有助动词Did,助动词后需接动词原形,因此第一个空应填动词原形;2. 答句时间状语为yesterday(昨天),表示过去发生的动作,谓语动词需用过去式,据此可确定两个空的正确形式,选出对应选项。
【解析】
根据一般过去时的语法规则:① 疑问句中有助动词Did时,实义动词用原形,故第一空填buy;② 答句描述的是昨天发生的动作,需用动词过去式,buy的过去式为bought,故第二空填bought,对应选项A。
【答案】
A
【知识点】
一般过去时、动词形式变化
【点评】

四、阅读理解。
★★★
① Zu Chongzhi was a famous mathematician
and an important scientist in China. When he
was a little boy, he took an interest in math and
science.
② Zu Chongzhi did something important
with circles(圆). For example, he found π was
very close to 3.1415926 and 3.1415927. It
helps us know how big a circle is. He also
wrote a great book on maths called Zhui Shu.
Now, we can read this book in Chinese,
Japanese, Korean and many other languages.
③ Zu Chongzhi always kept thinking when
he learned something new. He didn't just
believe what others said. He always wanted to
check if it was true. After his hard work, he
noticed something not true in the old calendar
(日历) so he made a new one called "Daming
Calendar". Also, he loved astronomy. He
watched the stars at night and wrote about his
findings carefully, because he wanted to know
how the stars moved across the sky.
④ Zu Chongzhi holds an important place in
the history of Chinese science and maths. His
findings make lots of changes in science and
maths. He is really a shining example to us.
1. · How does the writer
introduce Zu Chongzhi in Paragraph 2?
A. By using sayings.
B. By giving examples.
C. By asking questions.
D. By drawing pictures.
2. What does the underlined word "astronomy"

was very close to 3.1415926 and 3.1415927. It helps us
know how big a circle is. He also wrote a great book on
maths called Zhui Shu."可知,第②段通过举例子的方式介绍祖冲之。
2. D 词义猜测题。根据"He watched the stars at night
and wrote about his findings carefully, because he wanted
to know how the stars moved across the sky."可知,
astronomy是与星空有关的科学。
3. A 篇章结构题。根据文章内容可知,第①段是总述;第②③段主要介绍祖冲之在数学和创新方面的成就;第④段是总结。

解析

【分析】
1. 第1题解题思路:题目询问第②段介绍祖冲之的方式,需定位第②段内容,找到标志性表述“For example”,判断该段通过举例说明祖冲之的成就,对应选项。
2. 第2题解题思路:需猜测第③段划线词“astronomy”的含义,结合该词所在句的上下文(后文提到他观察星星、记录星空移动的发现),推断该词与天文、星空相关,匹配选项。
3. 第3题解题思路:需分析文章结构,先明确各段落主旨:第①段总述祖冲之的身份;第②③段分别介绍他在数学、天文历法等方面的成就;第④段总结他的历史地位,据此划分段落结构,匹配选项。
【解析】
1. 第1题:根据第②段中“For example, he found π was very close to 3.1415926 and 3.1415927... He also wrote a great book on maths called Zhui Shu.”可知,该段通过举例子的方式介绍祖冲之,故选B。
2. 第2题:根据第③段中“He watched the stars at night and wrote about his findings carefully, because he wanted to know how the stars moved across the sky.”可知,“astronomy”是与星星和天空相关的科学,故选D。
3. 第3题:第①段总述祖冲之的身份;第②③段分别介绍他在数学、天文历法等方面的成就;第④段总结他的历史地位,因此文章结构为①/②③/④,故选A。
