My name is Stella Young. I grew up in a very small country town in Victoria. I had a very
normal, low-key kind of upbringing. 1 went to school; I hung out with my friends; I fought
with my younger sisters. It was all very normal. And when I was 15, a member of my local
community approached my parents and wanted to submit my name for a community
achievement award. My parents said, "Hmm, that's really nice, but there's kind of one obvious
problem with that. She hasn't actually achieved anything.” And they were right. You know I
went to school, I got good marks, and I had a very low-key after-school job in my mum's
hairdressing salon.
Years later, I was on my second teaching round in a Melbourne high school, and l was
about 20 minutes into a year-1l Legal Studies class when a boy put up his hand and said,
"Hey Miss, when are you going to start your speech?”
And l said, "What speech?”
And he said, “You know, like, your motivational speaking. You know, when people in
wheelchairs come to school, they usually say, like, inspirational stuff. lt's usually in the big hall.”
And that was the moment I realized that this kid had only ever experienced disabled people
as objects of inspiration.
For lots of us, disabled people are not our teachers or our doctors. We're not real people.
We are there to inspire. Yeah, we've been sold the lie that disability is a bad thing, and to live
with a disability makes you exceptional.
It's not a bad thing, and it doesn't make you exceptional. And in the past few years, we've
been able to spread this lie even further through social media.
Life as a disabled person is actually somewhat difficult. We do overcome somethings. But they
have nothing to do with our bodies. I use the term “disabled people" purposely, because l
subscribe to what's called the social model of disability. This model tells us that we are more
disabled by the society that we live in than by our bodies and our diagnoses (诊断).
l want to live in a world where we don't have such low expectations of disabled people
that we are congratulated for getting out of bed and remembering our own names in the
morning. I want to live in a world where we value disabled people's real achievement. And I
want to live in a world where a year-11 kid in a Melbourne high school is not one bit surprised
that his new teacher is a wheelchair user.
24. What can we learn from Stella Young in the first paragraph?
A. She couldn't get along well with her friends and sisters.
B. She played a key role at her mum's hairdressing salon.
C. She received an award for a great achievement.
D. She lived an ordinary life in a country town.
25. What can we infer from the dialogue between Stella Young and the boy?
A. The boy didn't have much life experience.
B. People have fixed ideas about the disabled.
C. The disabled can’t find decent jobs because they are incapable.
D. Stella Young felt uncomfortable because of the boy's impoliteness.
26. According to the passage, Stella Young may agree that ______.
A. social media offends the public by spreading lies about the disabled
B. the disabled are less likely to be successful in their careers
C. society's attitude makes disabled people's life difficult
D. people's expectations of the disabled are too high
27. Which would be the best title for this passage?
A. On the journey to becoming exceptional
B. The secret behind my disability
C. Show sympathy to the disabled
D. I'm not your inspiration
C
Music is a powerful thing. It awakens feelings and has the power to bring people together.
But today, artists are not known for their music, but for how flashy their clothing is and how
many times their wealthy relatives can get them out of jail (监狱). And thus, their music is lost.
Pop and rap music has developed into a shallow, image-addicted industry that lines up with
what the public wants to hear and see, removing the focus on the actual music. Main stream
music is no longer composed of emotion, but instead, themes of money and fame. Photos
and rumors fly while the music is ignored.
Not all musical groups or individual artists begin like this. Many of these artists are
original and talented, but turn to the money side. Often their songs are written by experts
who know what is appealing to a certain age group, and the musicians' faces can be seen
on countless magazine covers. Soon their supposedly new and improved songs can be heard
blasting out of car windows. But these songs are totally empty, lacking creativity and the
original thirst of the artist to make an impact or convey (传递) a message.
MTV is not helping. It plays only what the public wants to hear. And unfortunately, the
majority seems interested in either sickly sweet, generic pop or stereotypical (刻板的),
bleeped-out rap. Kids and teens everywhere are swimming in these songs, which are often
degrading to women and minorities, and inappropriate.
Almost all the girls in my dorm are addicted to the same songs. This was the case the
previous year, and the year before that. Whenever l try to play music I enjoy, or introduce
them to some decent songs, they say that everyone except me likes their music.
Why do most teenagers only listen to pop and rap music when so many other types exist?
Maybe it's because everywhere we look, we are bombarded with the same music: on the radio,
on TV, on the computer. At school, pop and rap are discussed all the time. Perhaps they have
never listened to anything else. Or maybe peer pressure is part of it.
There is no solution to the “pop problem". It's called popular for a reason-many people
enjoy it. There's no easy way to change their views. My suggestion is not to buy music like
this when you can explore something new. Expand your horizons. Dig up your parents’ old
records and CDs. You never know what you might find.
28. The author probably prefers ______.
A. new pop songs meant for girls
B. original songs with deep meaning
C. catchy songs produced by popular singers
D. never-heard-before songs just recently discovered
29. What can we learn from the passage?
A. Many artists trade creativity for wealth and fame.
B. The public is responsible for the existence of music.
C. MTV promotes the songs favored by women and minorities.
D. Musicians singing about money is an ineffective way to attract fans.
30. What is most probably the author's suggestion for young people?
A. Try to respect your peers’ music tastes.
B. Deal with the "pop problem" patiently.
C. Expose yourself to various music styles.
D. Treasure the music from previous generations.
D
NASA will crash a spacecraft into an asteroid (小行星) to try to change its orbit,
attempting to prevent humans going the same way as the dinosaurs.
Earth is constantly being disturbed by small pieces of debris(碎片), but they usually burn
up or break up long before they hit the ground. Once in a while, however, something large
enough to do significant damage makes impact. About 66 million years ago, one such crash
is thought to have wiped out the dinosaurs. Someday, something similar could end human
beings—unless we can find a way to tackle it.
NASA's Double Asteroid Redirection Test (Dart) mission is the first attempt to test if such
asteroid redirection is a realistic strategy: investigating whether a spacecraft can
autonomously reach a target asteroid and intentionally crash into it, as well as measuring the
amount of redirection. "If it works, it would be a big deal, because it would prove that we
have the technical capability of protecting ourselves.," said Jay Tate, the director of the
National Near Earth Object Information Center.
