A.Should all cars be electric?
B.Will cars be common in the future?
C.Can electric cars help slow climate change?
D.Are gas-powered cars bad for the environment?
解析:A 标题归纳题。根据“I think we should all have electric cars ...”和“I don’t think all cars should be electric ...”可知本文主要介绍了两位学生对“所有汽车都是电动的”的看法。B项扩大主题；C、D项断章取义。

A

【分析】
本题是英语阅读理解中的标题归纳题，解题思路为：先梳理文本核心讨论的话题，再对比选项，选出最贴合核心话题的标题。文本围绕两位学生对“是否所有汽车都该是电动的”的不同看法展开，需抓住这一核心来判断选项。
【解析】
这是一道标题归纳题。文中Henry提出“I think we should all have electric cars...”，Sandy提出“I don’t think all cars should be electric...”，二者均围绕“是否所有汽车都该是电动的”这一话题讨论。分析选项：A项“Should all cars be electric?”（所有汽车都该是电动的吗？）完全贴合核心话题；B项“Will cars be common in the future?”（汽车未来会普及吗？）偏离讨论主题；C项“Can electric cars help slow climate change?”（电动车能帮助减缓气候变化吗？）、D项“Are gas-powered cars bad for the environment?”（燃油汽车对环境有害吗？）仅涉及部分内容，属于断章取义。因此选A。
【答案】
A

训练 3 A 标题归纳题。根据“As time goes by, the sport has become more than just a race ...”可知本文主要介绍了马拉松不仅仅是比赛,它是一段享受跑步、挑战自我和体验文化的旅程。B、C项以偏概全;D项无中生有。

【分析】
做英语阅读理解的标题归纳题时，需先定位文章核心主旨句，通常这类句子会出现在文章开头或转折处，再结合主旨对比选项，排除片面、无中生有的选项即可得出答案。本题中文章明确提到马拉松不只是比赛，这是核心主旨，围绕此分析选项即可。
【解析】
首先找到文章关键主旨句：“As time goes by, the sport has become more than just a race ...”，说明文章核心是强调马拉松不只是比赛。选项B“路线和规则”、C“历史和主题”在文中未提及，属于无中生有或以偏概全；选项D“每个人的比赛”文中无相关表述；只有选项A准确概括了文章主旨。

A
