2026年课时A计划八年级英语上册外研版第20页答案
(
A
)10. —Is Helen here?
—No,she isn’t here. She
in half an hour.

A.will arrive
B.has arrived
C.arrives
D.arrived

答案

10.A

解析

【分析】首先抓住句中的时间标志“in half an hour”,它表示“半小时后”,属于将来的时间,因此句子需使用一般将来时。接下来逐一分析选项的时态,匹配符合要求的选项。
【解析】句中时间状语“in half an hour”表明动作发生在将来,需用一般将来时。A项“will arrive”是一般将来时结构,符合语境;B项“has arrived”为现在完成时,强调过去动作对现在的影响,不符合;C项“arrives”是一般现在时,表经常性动作,不符合;D项“arrived”是一般过去时,表过去的动作,不符合。因此选A。
【答案】10.A
【知识点】一般将来时;时间状语与时态搭配
【点评】本题考查英语时态的基础应用,核心是识别表将来的时间状语,难度较低,属于易得分的基础题型。
【难度系数】0.7

解析

【分析】本题围绕现在完成时的句型转换展开,解题时需先明确各题核心考点:1题考查现在完成时的一般疑问句转换,需调整助动词和副词;2题考查短暂性动词与延续性动词的转换,适配时间段状语;3题考查现在完成时的否定句转换,需调整助动词和副词;4题考查对时间段提问的疑问词;5题考查现在完成时的改写,需匹配主语的助动词及动词过去分词。
【解析】1. 原句为现在完成时(结构:have+过去分词),改为一般疑问句时,将助动词Have提至句首,疑问句中already需改为yet,故填Have; worked。
2. 短暂性动词buy不能与表示时间段的for 3 years连用,需转换为延续性动词have/keep,主语Peter是第三人称单数,助动词用has,故填has had/kept。
3. 现在完成时的否定句结构为“have/has+not+过去分词”,主语The students是复数,故用haven't,already改为yet放句末,故填haven't visited; yet。
4. 画线部分“for about a month”是时间段,对其提问用疑问词组How long,故填How long。
5. 用just改写为现在完成时,主语She是第三人称单数,助动词用has,write的过去分词为written,故填has; written。
【答案】1. Have;worked 2. has had/kept 3. haven't visited; yet 4. How long 5. has;written
【知识点】现在完成时、句型转换、动词时态转换

解析

【分析】
本题为单词及短语的适当形式填空题,解题思路为:先明确方框内每个单词/短语的含义,再结合句子语境判断所需词性、时态或词形变化,最终选出正确形式。具体分析各题:1. 需填表示“成绩”的词,grade作成绩讲常用复数;2. 需形容词修饰艺术品,price转换为形容词表“无价的”;3. 由last year确定用动词过去式;4. 不定式后接动词原形;5. 由am确定用现在分词表将来。
【解析】
1. 句意:你还有机会取得好成绩,努力学习永不放弃。grade表示“成绩”时常用复数形式,故填grades;
2. 句意:你可以欣赏故宫里的无价艺术品。此处需形容词修饰名词artworks,price的形容词形式priceless意为“无价的”,符合语境,故填priceless;
3. 句意:这位歌手去年建立了自己的慈善机构来帮助有需要的人。由时间状语last year可知用一般过去时,set up的过去式仍为set,故填set up;
4. 句意:爸爸喜欢装扮成圣诞老人给孩子们送礼物。不定式符号to后接动词原形,give away意为“赠送”,符合语境,故填give away;
5. 句意:我正计划下个月去上海。由句中am可知此处用现在进行时表将来,plan的现在分词为planning,故填planning。
【答案】
1. grades 2. priceless 3. set up 4. give away 5. planning
