Ⅰ.阅读理解
A
When Narayanswami was invited to a dinner by a friend who worked at Nasa’s Jet
Propulsion Laboratory，she was excited.Many of the guests flew planes.“I must have expressed
some yearning(渴望)，” she says，because someone told her “You should join the flying
club！” The next day Narayanswami，who was 57 at the time ，arranged to meet an
instructor.“I said ‘Aren’t I too old？’ He said ‘We’ve got students in their 80s.’”
Narayanswami grew up in Southwest London，and at grammar school suffered horrific racist
bullying.The library provided shelter.But，as she reached her late teens，she felt family pressure
for an arranged marriage; “I really protested，” she says.“But I want to be an astronaut! My
mother made a promise：As long as you are getting an education，we will not look for a husband
for you.”
Narayanswami studied biology at Leicester University，then did a PhD at St Andrew，
followed by postdoctoral research at the University of California.“Every time you move，you get
further away，” her dad remarked on the phone.“I didn’t feel I would be able to escape unless
I did that，” she says.
In 2020，aged 64，Narayanswami finished 423 light hours she needed to earn her pilot’s
license.Then she applied to Nasa’s astronaut corps ， but received a very appreciative
rejection.Even now，at 66，she says “I haven’t been able to figure out how to deal with it.It
doesn’t go away.” The racist bullying she received as a child has cast a very long shadow.
Flying has helped.It is a workout: she has to tow the plane out to the taxiway.And it offers a
different perspective.“I can see eagles，bears，mountain lions，birds of prey.I love the beauty of
the clouds.They are like hills.Vaster than our hills，” she says.
New possibilities have arisen—Narayanswami chairs the board of the General Aviation
Awards in the US—but she finds relaxing difficult.In flight，she is “part of a huge network of
people who are communicating by radio frequency.There is no sense of skin colour.We are all tied
together by our voices.”
1．How did the instructor’s words sound to Narayanswami?
A．Disappointing. B．Embarrassing.
C．Annoying. D．Encouraging.
2．What does the underlined word “that” in paragraph 3 refer to?
A．Accepting an arranged marriage.
B．Receiving an education.C．Keeping a distance.
D．Making a promise.
3．What does Narayanswami think of Nasa’s rejection?
A．It indicates prejudice against her.
B．It ruins her childhood memory.
C．It raises concern for her age.
D．It leaves room for negotiation.
4．What does flying bring to Narayanswami?
A．A good way of relaxation.
B．A different dimension of life.
C．A rich knowledge of wildlife.
D．A full exhibition of leadership.

Although it is a business not many are aware of，sidewalk robots are set to become an
industry with annual sales of $1 billion within a decade.These four- or six-wheeled autonomous
machines，usually the size of a suitcase，are already delivering groceries in America，China and
Europe，which puts them ahead of many driverless cars and lorries being developed.
Those bigger vehicles are held back not by technology but regulation.This means having a
“safety driver” on board ready to take over if there is a problem，which is hardly labour-
saving.For these larger vehicles，regulators want to see safety systems thoroughly proved.In
January 2022，Britain’s Law Commission，which reviews lawmaking，recommended that it
should not be the person in the driver’s seat who faces prosecution if a vehicle in autonomous
mode crashes，but the manufacturer or the body that sought approval for its use.
However，sidewalk robots are getting on with the job.For example，Starship Technologies，
based in San Francisco，estimates it has already clocked up more than 2.5 million deliveries with
robots in a number of cities，universities and business parks in Europe and America.Amazon is
carrying out trials with a similar sort of machine.Kiwibot，a Colombian startup，is making
sidewalk deliveries in California.Udelv，a Californian firm，is developing a larger type called
Transporter to operate at highway speeds.
Sidewalk robots carry a few bags of groceries using a variety of sensors ， including
cameras，radar and GPS to navigate and avoid obstacles and people.Their progress can be
monitored on a phone app，which also unlocks them for goods to be removed.As they are small，
move slowly and are “telemonitored” by people in a control room who can take over，
authorities seem more willing to give them a green light.
Such robots are becoming more autonomous.Being much further along the road in earning
their keep，these delivery robots are helping to pave the way for the time when bigger autonomous
vehicles can join them.5．What is paragraph 2 mainly about?
A．Problems caused by autonomous cars.
B．Suggestions for producing intelligent robots.
C．Challenges faced by large driverless vehicles.
D．The innovative technology of delivery vehicles.
6．Why does the author give some examples in paragraph 3?
A．To prove the safety of autonomous machines.
B．To present the development of sidewalk robots.
C．To encourage the public to create more robots.
D．To show the advantages of self-driving technology.
7．What can we know about sidewalk robots?
A．They are environmentally friendly.
B．They can distinguish traffic lights on the road.
C．They make deliveries faster than ordinary trucks.
D．They make it easy for people to track the delivery process.
8．Which section of a magazine is this text probably taken from?
A．Sports and music.
B．Business and culture.
C．Science and technology.
D．Nature and geography.

Ⅲ.语法填空
(2023·河北九师联盟联考)
I can well remember that I was once asked to deliver a speech titled “A Real Test in My
Life” before the whole class at the age of 9! You can imagine how 1. (terrible) shy
I was with so many eyes 2. (fix) upon me. I had no 3. (choose) but toprepare for it, though.
First of all，I was to draft the speech, which was just a piece of cake for me, a good writer.But
the hardest part 4. (lie) in my oral presentation from my memory—for to read from
the paper was not allowed. The real moment began 5. I stood on the platform with
my legs trembling and my mind blank. But my listeners were waiting patiently without any signs of
rushing me. Gradually I found myself back, 6. (deliver) my speech with difficulty.
After 7. seemed to be a hundred years, I found my audience applauding—I made it!
From then on, my fear of talking before the audience disappeared.
Actually with my 8. (confident) building up, I now turn out to be a great
speaker. Looking back, I know the greatest difficulty on our way 9. success is our
fear. Overcome it 10. we will be able to achieve our goals.
