14.Almost all of us have been there:A sense of uneasiness strikes us when we see the battery running low on the smartphone.While today's smartphones enable us to surf the Internet,take pictures and play music,their limited,sometimes annoyingly short battery life has started to make people full of memories of early models."My favorite phone of all time was a silver Nokia 6310i from the early 2000s.It may be primitive by today's standards,but it could run for 17days on a single charge,"wrote Daily Mail columnist David Derbyshire.But scientists spend no time thinking about the past.They have built an aluminium (铝) battery which could be a cheap,fast-charging alternative to current designs.
You can squeeze,and practically bend it in half without breaking the packet.It is more environmentally friendly than alkaline (碱性的) batteries,and more safe than lithium (锂) batteries-it won't catch fire"even if you drill through it",as Hongjie Dai of Stanford University told The Telegraph.The battery is the work of a team led by Dai.And the best part is that it has a recharge time of around one minute.
However,at present,the only problem is that it produces just half the voltage (电压) of a typical lithium battery.But Dai explained they were setting about changing the voltage and energy density(密度)"."Our battery has everything else you'd dream that a battery should have.I see this as a new battery in its early days,"he told The Telegraph.
72.How many advantages does the aluminium battery have according to the article?C
A.2
B.3
C.4
D.5
73.The passage suggests thatB.
A.the aluminium battery catches fire easily if drilled
B.the aluminium battery still needs improving before it can be widely used
C.the aluminium battery is larger in size than alkaline batteries
D.scientists find it a real challenge to change the voltage of the aluminium battery
74.Which of the following can best summarize the passage?D
A.A new battery in its early days.
B.A new trend in the smartphone market.
C.The annoyance short battery life causes
D.The invention of a new smartphone battery.
75.The last paragraph in the passage is probably followed by the paragraph about how toC.
A.make the aluminium battery cheaper and more environmentally-friendly
B.lengthen the aluminium battery life
C.increase the voltage and energy density of the aluminium battery
D.charge the aluminium battery faster.
分析 本文是科普说明文.主要介绍了一种新型的智能手机电池的发明以及这种电池的优势和不足.
解答 26.答案 C 考查细节辨析题.根据题干关键词How manyadvantages does the aluminium battery找到文章的对应段落是第二段,其中的第二句They have built an aluminium (铝) battery which could be a cheap,fast-charging alternative to current designs和第三段的Youcan squeeze,and practically bend it in half without breaking the packet.It ismore environmentally friendly than alkaline (碱性的)batteries,and more safe than lithium (锂)batteries-it won't catch fire"even if you drill through it"可知该电池具有cheap,fast-chargingalternative,more environmentally friendly,more safe四个优点,故选C.
27.答案 B 考查判断推理题.根据文章第三段的It is more environmentallyfriendly than alkaline (碱性的) batteries,and more safethan lithium (锂) batteries-it won't catchfire"even if you drill through it排除A;根据文章第三段的It is more environmentally friendly thanalkaline (碱性的) batteries排除C;根据文章最后一段的ButDai explained they were setting about changing the voltage and energy density(密度)"排除D;根据文章最后一段的Our battery has everything else you'ddream that a battery should have.I see this as a new battery in its early days判断选B.
28.答案 D 考查主旨大意题.A.A new battery in its early days一种早期的新电池;B.A new trend in the smartphone market智能手机市场的一种新潮流;C.The annoyance short battery lifecauses短期电池寿命让人烦;D.The invention of a newsmartphone battery新智能手机电池的发明.通读全文,并根据文章的第二段和最后一段可知本文是介绍的尚在早期阶段的一种智能手机新电池的发明.故选D.
29.答案 C 考查判断推理题.根据文章最后一段的But Dai explained they weresetting about changing the voltage and energy density(密度)"."Our battery has everything elseyou'd dream that a battery should have.I see this as a new battery in itsearly days,"he told The Telegraph.推断下一段将讨论如何增加这种新型电池的密度和电压.故选C.
点评 科普知识与现代技术是高中课程标准规定的话题之一.此类题材的文章涉及内容广泛,如天文地理、生物医药、发明创造、计算机技术等等.这类文章的总体特点是:科技词汇多,句子结构复杂,理论性强,逻辑严谨.具体说来它有以下几个特点:
1.文章中词汇的意义比较单一、稳定、简明,不带感情色彩,具有单一性和准确性的特点.
2.句子结构较复杂,语法分析较困难.为了描述一个客观事物,严密地表达自己的思想,作者经常会使用集多种语法现象于一体的长句.
3.常使用被动语态,尤其是一些惯用被动句式.
4.科技环保类文章在高考英语试题中出现的频率最高,一直是高考的主要测试内容,此类文章一般为说明文,但也常常夹杂着叙述和议论,并经常出现一些较新的科技名词或术语.着重从不同侧面考查学生筛选、提取、推断信息的能力.考生若经常阅读英语报刊,具备丰富的课外知识,并积累一定的时新词汇,对解读此类文章会大有帮助.
