(2020·郑州第二次质检)Something strange has been happening to me lately: Women

in the street have been telling me I'm brave.

My act of courage isn't much—I just stopped coloring my hair.I had brown hair

that started going gray when I was ，like a lot of women，I started dyeing(染)

was expensive and time­ my hair grows fast，so I needed to go back to

the hair salon(美发厅)every 5 weeks.

Many people seem to enjoy holding onto their youth for as long as possible，

giving others the impression that they don't have much wisdom or many

our hair starts to turn gray and suddenly we start spending $500

or more a year to cover something our male colleagues don't need to cover.

Of course，people should do what they want to do with their own body—my mother

is 91 and still has“blonde” hair，and why not？I just wish more of us would feel

that it is OK to be ourselves，because going gray has done more for me than saving

me time and money.

I like my natural hair，just as it is.I like how it has got curly is

recovering after years of being damaged by chemicals.I also like that it has given

me some needed attitude in a society that makes youth seem so important，while being

against reminds me that I'm not a kid anymore and this isn't a bad

being a kid anymore means I read the books I want，and not the books I feel I should

means not wasting my time at events I don't need to attend when I'd rather

be with my family and friends.

When I see my hair in the mirror，it's a reminder that my time is limited，and

I should spend it doing what 's nothing shameful about growing

pretending it's not happening is a way of giving up our power.

I see my gray hair as a little act of rebellion(反叛)against the idea that people

lose value as they age，instead of gaining it.I see gray hair as my “flag” and I'm

letting it fly proudly.

(2020·山东省济南市第二次模考)The Walt Disney Company has built a room that can

wirelessly power and charge any devices ss charging usually only works

when a device is touching a power researchers say they have found a way

to provide wireless power and charging capability to large areas.

A scientific team from Disney Research recently demonstrated the

n Sample is the lead researcher at Disney explained the

goal of the project in a video. “What we really want is a three­dimensional charging

experience where you walk into your living room or office and your cell phone is charged

simply by walking in.”

The process uses magnetic fields to send power to specially designed receivers.

Researchers built a 54­cubic­meter room in which the walls，floor and ceiling

were covered with metal placed a long metal pipe in the middle of the

ical currents travel up and down this pole about 1.3 million times per

currents also move through the ceiling，walls and floor，before flowing

again up the devices inside the pole set the level of electromagnetic

waves continuously move around the room to send power to receiving

Disney researchers said repeated experiments led to successful wireless

power transfers to many devices running at the same time.

One of the concerns of electric fields is that they can be harmful to

associate research scientist Matt Chabalko said the level of power being produced

inside the room is not dangerous.“Our simulations show that we can transmit 1.9

kilowatts of power while meeting federal safety means it's completely

safe for people to occupy this space for any amount of time.”

The experiments also showed that furniture inside the room was not damaged and

did not block the wireless of Disney's likely uses for wireless power will

be to create areas at its parks where visitors can charge their devices.

了。

5．Which of the following can replace the underlined word“demonstrated” in

Paragraph 2?

A．Believed. B．Showed.

C．Improved. D．Chose.

解析：词义猜测题。根据后面的“He explained the goal of the project in a video.”

B．What is needed to charge wirelessly.

C．What devices can be charged in the room.

D．How wireless charge functions in the room.

答案：D

7．Why did the author mention the danger of wireless charge?

A．To get rid of people's worry.

B．To remind people of its existence.

C．To show the way to solve it.

D．To explain how harmful it is.

C

(2020·山西六校二次质检)In elementary school，Glenn Cameron was very aware of

the challenges faced by his friend，Roger，who had lost a he has built an

artificial helper for him.

The robotic hand is called “Dexi”．Each of its fingers can move

strength and speed of the hand's “muscles” can be 's also created a

digital version of this hand，which responds on a computer h a special

headset，the system takes electrical signals from a human brain，sends them to a

computer，and then the computer “tells” the hand what to example，to make

the hand close，you “see” a fist in your head.

In fact，Cameron's first robotic hand was 3D printed ing the hand

was too limited，he decided to build his was quite a challenge，but his new

version was was also cheap，compared to many other robotic hand

n says designing and building the hand was hard，but he went

came the one Roger is using.

Cameron is working on a hand that can actually be used by a person who's lost

a hand at says the new hand will be simpler，because there won't be as

much make up for this，he's adding a mini camera and trying to make the hand

smarter.

Cameron encourages young people who think they might want to do something

demanding and similar，“You just begin working towards one little step at

a time，purposeful and steadfast，sooner or later you're going to get to the place

you long for.”

[语篇解读] 在小学的时候，Glenn Cameron看到朋友缺少一只手，内心很受触动，他现

在已经制造出了可以由人脑控制的机械手来帮助朋友。

9．Which version of the artificial hand does Dexi belong to?

A．The first. B．The second.

C．The third. D．The fourth.

解析：推理判断题。Dexi出现在第二段，但本题要结合上下文内容来推理才能得到答案。

根据第一段的尾句和第二段的开头可知，Dexi是Roger现在使用的机械手版本。第三段谈到

Cameron制作的第一个机械手是3D打印出来的，但他不满意。于是，他花费时间制造了第二

个版本的机械手，这个版本比第一个要好。但他继续研发，于是便有了第三代机械手——Roger

现在使用的Dexi。

答案：C

10．How could a user of the digital version of Dexi control the robotic hand?

A．By operating the computer.

B．By thinking.

C．By sending electrical signals to the hand.

D．By speaking.

解析：细节理解题。根据第二段的“Through a special headset，the system takes

electrical signals from a human brain，sends them to a computer，and then the computer

‘tells’ the hand what to example，to make the hand close，you ‘see’ a fist

in your head.”可知，Dexi的数字版本通过特殊的头部装置，收集大脑发出的电子信号并发

送给电脑，电脑“告诉”机械手要做什么。比如，为了把手握起来，你可以在你的脑海中“看

到”一个拳头。由此可推知，这个版本的机械手的使用者可以通过“想”来操作机械手。

答案：B

11．Which saying do Cameron's words convey?

A．Well begun is half done.

B．The longest journey begins with the first step.

C．All things are difficult before they are easy.

只要开始朝着它努力，一步一个脚印，坚定信念，迟早你会到达想去的地方，即实现目标。D

项“Nothing is impossible to a willing heart.(有志者，事竟成)”与他的话所表达的意

思一致。

答案：D

12．What is the text mainly about?

A．Cameron's brain­controlled robotic hands.

B．Cameron's story of success.

C．The latest designs of artificial intelligence hands.

D．A robotic helper for the disabled.

解析：主旨大意题。全文主要讲了Cameron为帮助失去手的人而设计和制造的机械手，

故选A项。

答案：A
