5.Jim was walking on the street

答案

一、1.While/When 2.When 3.while 4.when
5.when

解析

【分析】首先明确when和while引导时间状语从句的核心区别:when可搭配延续性动词或短暂性动词,从句时态无严格限制;while仅搭配延续性动词,从句常用进行时态。接下来结合每个句子的动作类型判断:1句中Mary was reading是延续性动作,Lisa arrived是短暂性动作,可选用While或When;2句表“苏珊十岁时”的时间点,用When;3句两个均为过去进行时的延续性动作,表同时进行,用while;4句“事故发生”是短暂性动作,用when;5句“发现手表”是短暂性动作,用when。
【解析】1. 从句动作Mary was reading是延续性动作,主句动作Lisa arrived是短暂性动作,故填While/When;2. 此处表示“当苏珊十岁时”,指时间点,用When;3. 两个动作均为过去进行时的延续性动作,强调同时进行,用while;4. “事故发生”是短暂性动作,用when;5. “发现手表”是短暂性动作,用when。
【答案】1.While/When 2.When 3.while 4.when 5.when
【知识点】时间状语从句,when与while的用法
【点评】本题聚焦初中英语中when和while引导时间状语从句的基础用法,需准确区分两者适用的动作类型,是时态考点的常见题型,难度适中,需注意延续性与短暂性动词的判断。

二、用括号内所给单词的适当形式填空
6.Betty
was reading
(read) a magazine at eight yesterday evening.
7.Alice

(not do) her homework when her mum came back.
8.Bill hurt himself while he

—Sorry,I
was taking
(take) a shower.
10.While we
were singing
(sing) an English song, some visitors came into our class.

答案

二、6.was reading 7.wasn't doing 8.was cooking
9.was taking 10.were singing

解析

【分析】这几道题考查英语中过去进行时的用法,解题思路为:先根据句中的时间状语(如at eight yesterday evening)或when/while引导的从句(从句用一般过去时),判断动作是过去某个时刻/时间段正在进行的;再结合主语的单复数确定be动词的形式(单数用was,复数用were),最后将动词变为现在分词形式,否定句则在be动词后加not。
【解析】6. 句中时间状语“at eight yesterday evening”表示过去具体时刻,需用过去进行时,主语Betty为单数,故填was reading;7. when引导的从句是一般过去时,主句表示妈妈回来时Alice未在做作业,用过去进行时的否定形式,主语Alice为单数,故填wasn't doing;8. while引导的从句表示过去正在进行的动作,主句是一般过去时,主语he为单数,故填was cooking;9. 问句询问过去某时刻正在做的事,答语用过去进行时,主语是I,故填was taking;10. while引导的从句表示过去正在唱歌的动作,主句是一般过去时,主语we为复数,故填were singing。
【答案】6.was reading 7.wasn't doing 8.was cooking 9.was taking 10.were singing
【知识点】过去进行时、动词适当形式填空
【点评】本题聚焦过去进行时的核心用法,需准确判断时态语境和主谓语单复数,是初中英语时态的基础考点,难度适中。
【难度系数】0.5
三、按要求完成下列句子
11.Ben took a shower last night.(用at 8:00 last night改写句子)

答案

三、11.was taking 12.Was;doing 13.I wasn't
14.What were;doing

解析

【分析】
本题考查过去进行时的相关句式转换,需结合时间状语判断时态,再根据不同句式(陈述句改进行时、一般疑问句、特殊疑问句、答语)的变化规则解题:
1. 第11题:时间状语at 8:00 last night是过去具体时刻,需将原一般过去时改为过去进行时,结构为was/were + 现在分词,结合主语确定be动词;
2. 第12题:过去进行时陈述句改一般疑问句,需提前be动词;
3. 第13题:过去进行时一般疑问句的否定回答,需对应主语调整be动词形式;
4. 第14题:对过去正在进行的动作提问,用疑问词What,结合主语和过去进行时结构构成特殊疑问句。
【解析】
11. 时间状语at 8:00 last night表过去具体时刻,句子需用过去进行时,结构为“was/were + 现在分词”,主语Ben为第三人称单数,be动词用was,take的现在分词是taking,故填was taking;
12. 过去进行时的陈述句变一般疑问句,需将句中be动词was提前至句首,后面动词用现在分词doing,故填Was; doing;
13. 以Were you开头的过去进行时一般疑问句,否定回答主语对应为I,be动词用was的否定形式wasn't,故填I wasn't;
14. 画线部分是过去正在进行的动作,提问“正在做什么”用疑问词What,主语是you,be动词用were,后面接doing,故填What were; doing;
【答案】
三、11.was taking 12.Was;doing 13.I wasn't 14.What were;doing
【知识点】
过去进行时、句型转换
【点评】
本题围绕过去进行时的核心考点设置,涵盖时态转换的基础题型,需熟练掌握过去进行时的结构及各类句式的变化规则,是初中英语时态应用的典型基础题。
