For
a year and a half, kids sent hurtful messages like "You are so ugly."
or "Why are you still alive " to Rebecca Sedwick. In 2013, Rebecca,
then 12, couldn't stand it anymore. She jumped to her death near her home in
Florida. Soon afterward, Trisha Prabhu read about the story. "I was
surprised and heartbroken," says Trisha, now 15, who is from Naperville,
Illinois." I knew that I had to do something to stop this from ever
happening again."
Trisha
did some research. Studies show that one fourth to half of all teens in the US
have been cyberbullied(网络欺凌). Experts say
that if you are ever bullied online, you should tell a trusted adult. Tell the
cyberbully to stop, and prevent him or her from contacting(联系) you again. Print and save messages to share with the police. This
is good advice, agrees Trisha. But these methods all take place after the
bullying has already happened. Trisha had a different idea. Why not teach
cyberbullies to stop before they post these messages
Trisha's
research won awards, including a prize in the Google Science Fair. Then, Trisha
built the ReThink app (应用软件). It is
programmed to recognize words or phrases that could be hurtful. When that
happens, different warning messages come out. "Don't say things that you
may regret later!" says one message. Others ask, "Are you sure you
want to say this?" and "Are these words
really yours?"
Now
Trisha is working on a version(版本) of ReThink for
computers. "I'm a big dreamer," she says. "I want to stop
cyberbullying before the hurt is done."
(1)What do we know about Rebecca Sedwick
A.She ended her life at the age of 12.
B.She sent hurtful messages to others.
C.She was one of Trisha's best friends.
D.She went to Florida to study further.
(2)What is Trisha's suggestion for stopping cyberbullying
A.Stop talking with the cyberbully.
B.Stop the messages before they are sent.
C.Turn to your parents or close friends.
D.Show the messages to the police at once.
(3)What is the third paragraph mainly about
A.People's attitudes to the ReThink app.
B.Trisha's research on cyberbullying.
C.How the ReThink app works.
D.The Google Science Fair.
(4)Which of the following can best describe Trisha
A.Helpful and clever. B.Honest and careful.
C.Proud and impolite. D.Strange and impatient.
【答案】(1)A
(2)B
(3)C
(4)A
【解析】【分析】本文是一篇记叙文,为了防止同龄人受到网络暴力的威胁,一个美国女孩设计出了一款名为ReThink的应用软件。
(1)考查细节理解。根据第一段中的“In 2013, Rebecca, then 12... jumped to her death...”可知,Rebecca在十二岁的时候结束了自己年轻的生命,故选A。
(2)考查细节理解。根据第二段中的“Trisha had a different idea. Why not teach cyberbullies to stop before they post these messages?”可知,Trisha认为阻止网络暴力的最好办法首先是阻止这些信息散发出去,故选B。
(3)考查段落大意。本段主要介绍了ReThink这款应用软件的工作原理,故选C。
(4)考查推理判断。为了防止同龄人受到网络暴力的威胁,Trisha运用自己的聪明才智设计出了ReThink这款应用软件,所以她是一个乐于助人而且非常聪明的孩子,故选A。
【点评】本题考点涉及细节理解,推理判断和段落大意三个题型的考查,是一篇故事类阅读,考生需要准确捕捉细节信息,并根据上下文进行逻辑推理,概括归纳,从而选出正确答案。
阅读理解
Traditionally, robots have been hard, made of metal and other hard material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot — one that draws inspiration (灵感) from an octopus (章鱼).
Described in science journal Nature, the "Octobot" could pave the way for more effective autonomous robots that could be used in the search, rescue and exploration. "The Octobot is a minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots," the study's authors wrote.
Robots built for precise, repetitive movements in a controlled environment don't do so well on the rough ground or in unpredictable conditions. And they aren't especially safe around humans because they're made out of hard and heavy parts that could be possibly dangerous to their users.
So researchers have been working on building soft robots for several ten years. They've taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more soft matter.
But creating a completely soft robot remains a problem. Even if engineers build a silicone (硅酮) body, it's still a big challenge to make soft versions of essential parts, such as a source of power.
"Although soft robotics is still in its early stage, it holds great prospects for several applications, such as searches and rescue operations and exploration", Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology's Center for MicroBioRobotics wrote. "Soft robots might also open up new ways to improving wellness and the quality of life."
37.What's the special feature of the Octobot
A.It's completely soft. B.It's made of hard metal.
C.It's very small. D.It looks like an octopus.
38.What's the disadvantage of traditional robots
A.They're hard to control.
B.They're too heavy to be moved.
C.They can't predict conditions.
D.They can't behave well all the time.
39.One of the biggest difficulties is to build soft robots' ____.
A.silicone body B.complex parts
C.precise movements D.soft power source
40.What's the possible application of the Octobot
A.Medical research. B.Life rescue.
C.Machine operation. D.House cleaning.
【答案】37.A
38.D
39.D
40.B
【解析】【分析】本文是一篇说明文,介绍了章鱼机器人的优点和投入应用的可能性。
【点评】本题考点涉及细节理解和推理判断两个题型的考查,是一篇科技类阅读,通读全文,理解文章大意,阅读题目后返回原文阅读并找出与题目相对应的内容,仔细核对,选择符合原文原意的答案,完成后再次阅读并检查。
37.考查细节理解。根据第一段 中的"robots have been hard, made of metal"机器人是坚硬的,由金属制成;以及"has managed to build an entirely soft robot — one that draws inspiration (灵感) from an octopus (章鱼)."成功地制造了一个完全柔软的机器人——一个从章鱼身上汲取灵感的机器人。可知,Octobot机器人特点是它很柔软。故选A。
38.考查推理判断。根据第三段中的"Robots built for precise, repetitive movements in a controlled environment don't do so well on the rough ground or in unpredictable conditions. "为在受控环境中进行精确、重复运动而设计的机器人在粗糙的地面或不可预测的条件下表现不佳;以及本段内容可知,传统机器人无法在崎岖的地形上很好地运行,此外,由于沉重的金属部件,传统机器人可能会对人体产生伤害,可推知,传统机器人的缺点是他们不能一直表现得很好。故选D。
39.考查细节理解。根据倒数第二段中的" Even if engineers build a silicone (硅酮) body, it's still a big challenge to make soft versions of essential parts, such as a source of power."即使工程师利用硅酮制造出了软体机器人的身体,但是制作柔韧性强的关键部件仍然面临巨大的挑战,比如动力来源。可知,最大的挑战之一是柔韧性强的动力来源,故选D。
40.考查细节理解。根据最后一段中的"Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration,"尽管对软体机器人的开发和研究还处于早期阶段,但它适用于诸如搜索救援和探索等任务,故选B。

Traditionally, robots have been hard, made of metal and other hard material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot — one that draws inspiration (灵感) from an octopus (章鱼).
Described in science journal Nature, the "Octobot" could pave the way for more effective autonomous robots that could be used in the search, rescue and exploration. "The Octobot is a minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots," the study's authors wrote.
Robots built for precise, repetitive movements in a controlled environment don't do so well on the rough ground or in unpredictable conditions. And they aren't especially safe around humans because they're made out of hard and heavy parts that could be possibly dangerous to their users.
So researchers have been working on building soft robots for several ten years. They've taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more soft matter.
But creating a completely soft robot remains a problem. Even if engineers build a silicone (硅酮) body, it's still a big challenge to make soft versions of essential parts, such as a source of power.
"Although soft robotics is still in its early stage, it holds great prospects for several applications, such as searches and rescue operations and exploration", Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology's Center for MicroBioRobotics wrote. "Soft robots might also open up new ways to improving wellness and the quality of life."
