If we were asked exactly what we were doing a year ago，we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day，we should be able to give an answer to the question.

It is the same in history .Many things have been forgotten because we do not have any written account of them .Sometimes men did keep a record of the most important happenings in their country，but often it was destroyed by fire or in a war．Sometimes there was never any written record at all because the people of that time and place did not know how to write．For example，we know a good deal about the people who lived in China 4，000 years ago, because they could write and leave written records for those who lived after them．But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to write．

Sometimes, of course，even if the people cannot write，they may know something of the past．They have heard about it from older people，and often songs and dances and stories have been made about the most important happenings，and these have been sung and acted  and told for many generations, for most people are proud to tell what their fathers did in the past．This we may call  “remembered history”．Some of it has now been written down. It is not so exact or so valuable to us as written history is，because words are much more easily changed when used again and again in speech than when copied in writing．But where there are no written records，such spoken stories are often very helpful．

1.Which of the following ideas is not suggested in the passage?

2.We know very little about the central Africa 200 years ago because ___

3.“Remembered history” refers to ___．

4.“Remembered history”is regarded as valuable only when ____.

5.The passage suggests that we could have learned much more about our past than we do now if the ancient people had _____

I was watching Family Feud a few years ago when they asked something like “What’s one thing you want your pilot to be?” And one of the answers was “A man.” Yes, I was upset, but that just inspired me more. It’s rare enough to see women pilots — for the first two years of my flight training classes, I was the only female student — and even more unusual to see a pilot who’s a woman of color. Black women make up about 7 percent of the U.S. population, but less than 1 percent of pilots. And of course, most of them are a bit older than I am. I just graduated from high school in May.

My mom is crazy about aviation (航空), so she always took me to air shows when I was younger. We’d watch the Thunderbirds or Blue Angles, and I’d get pilots’ autographs (亲笔签名). With her encouragement, I started taking lessons after I turned 12. Friends would ask me to hang out, and I’d say, “Sorry, I have a flight” — they’d look at me as if I had four heads. But the air felt like where I was supposed to be.

Flying is amazing for many reasons. You can see the beauty only from above and visit impressive places. But to me, one of the coolest things is being in charge of the plane and holding the controls. I plan to fly the big jets as an airline transport pilot, which means doing lots of ground training, banking 1,500 hours of flight time, and earning a bunch of certificates.

On my first plane ride when I was 4, the flight attendants (乘务员) gave me a little pin with wings. We took a picture of me standing next to the captain. Who would have guessed that someday I’d be sitting in his seat?

1.Why did the author feel upset after hearing the answer?

A. It was too simple.　　 B. It dealt with racial differences.

C. It talked about pilots negatively.　　 D. It was prejudiced against women.

2.What does the author say about black women?

A. They are uncommon sights in flight training classes.

B. They make up 7 percent of the U.S. pilots.

C. Most of them are high school graduates.

D. Few of them are interested in aviation.

3.What’s the author’s mom’s attitude to her becoming a pilot?

A. Skeptical.　　 B. Supportive.

C. Unconcerned.　　 D. Disapproving.

4.What happened when the author was four years old?

A. She sat in a captain’s seat.　　 B. She had a hard plane ride.

C. She was gifted a winged pin.　　 D. She helped some flight attendants.

It all started when Campbell Remess was nine years old and asked his parents if he could buy Christmas gifts for sick children, for he wanted to do something to brighten their spirits. His parents had to turn down his request, for Campbell is one of nine children and ... well, money, you know? However, Campbell took up the challenge and started creating his own bears. Meanwhile, he named the project “Project 365" , which means making a bear a day in a year.

Every week he delivers some bears to sick children not only at the Royal Hobart Hospital near his home but all over the world. He even creates personalized teddy bears, the Winning Bear, for cancer patients to hold onto during treatments and at those down times. Campbell has even sent bears to victims of terrorist attacks in Brussels and Paris. These bears all become a treasured companion and are something to hug during difficult times. But it doesn't end there ...

Not only does Campbell make bears, but he has a variety of fundraising events to help further causes he supports. At one such gala last year, Campbell made a bear on-stage and auctioned （拍卖）it off for $ 5 ,000. The night raised more than 26,000 for the Love Your Sister charity. He hopes to expand the amount and locations of fundraising events he hosts.

Campbell's message of love and kindness has spread around the world, and he has spoken to schools about how each effort counts. Project 365's Facebook page has amassed over 26,271 followers and is a platform for people worldwide to spread positivity.

As recently as 15 years ago, if you wanted to catch up on the news, you could look at a handful of publications or a few nightly programs. And if you wanted to listen to music, you could turn on MTV or fiddle with your radio. People in major cities had more options, because a large population can support specialty shops. 1..

Today, as we all know, access to information has exploded. One consequence, according to Toure, a cultural critic writing in Salon, is that the ability of pop culture to unify us-- he refers to the massive interest in Michael Jackson’s Thriller, or Nirvana’s Nevermind--has been eroded, probably forever. Steven Hyden, also writing in Salon, counters that whatever the advantages and disadvantages of a centralized pop-culture authority, the monoculture never actually existed.

2. Even when it supposedly existed, its content largely depended on other characteristics of your little corner of the world. In the 1992-1993 school year, I was a student at a multiracial and relatively urban junior high school in California’s central valley. We listened to Salt-n-Pepa, Snoop Doggy Dogg, and Kris Kross, with the latter having inspired a trend in which kids wore their clothes backwards. The next year I was enrolled in a mostly white junior high　 school in leafy Chiago suburb. One of the houses was famous for having appeared in the 1990 film “Home Alone”; the popular bands were Nirvana, Hole and the Smashing Pumpkins; and the biggest pop-cultural event of the school year was Kurt Cobain’s suicide.

But Toure’s point is about the virtues of common cultural experience. It seems he is recalling centralized media only in so far as it’s a distribution system that fostered ( 促进) that outcome.

3. It doesn’t matter whether a record is released by an important label or an indie ( 独立制片人); if it’s online, people can usually find, forward, share and promote it. But what’s interesting and perhaps surprising, given that both Toure and Mr Hyden seem to agree that the old distribution favored big media, is that we still have widely shared cultural experiences. Just think of Barack Obama doing the little hand gesture from Beyonce’s “Single Ladies ” video.

4.. It’s safe to say that the monoculture never really existed, and that some artists still reach a wide audience, whether we like it or not.

A.That suggests that we like pop culture partly because it’s a shared experience, regardless of quality.

B.However, in vast areas of the world you had to work to get outside the mainstream.

C.Whether you like it or not, “monoculture” is here with us.

D.I think Mr Hyden is correct that the concept of a “monoculture” is a bit of a myth.

E.They see globalization as being the spread of a monoculture, based on western values, which is killing the cultural diversity of the world.

F.And it’s true that the ways we now consume pop culture to some extent level the playing field.

A few years ago, Paul Gerner began to gather a group of architects in Las Vegas to ask them what it would take to design a public school that used 50 percent less energy, cost much less to build and obviously improved student learning. “I think half of them fell off their chairs,” Gerner says.

Gerner manages school facilities （设施） for Clark County, Nevada, a district roughly the size of Massachusetts. By 2018, 143,000 additional students will enter the already crowded public-education system. Gerner needs 73 new schools to house them. Four architecture teams have nearly finished designing primary school prototypes （样品）; they plan to construct their schools starting in 2009. The district will then assess how well the schools perform, and three winners will copy those designs in 50 to 70 new buildings.

Green schools are appearing all over, but in Clark County, which stands out for its vastness, such aggressive targets are difficult because design requirements like more natural light for students go against the realities of a desert climate. “One of the biggest challenges is getting the right site orientation （朝向）,” Mark McGinty, a director at SH Architecture, says. His firm recently completed a high school in Las Vegas. “You have the same building, same set of windows, but if its orientation is incorrect and it faces the sun, it will be really expensive to cool.”

Surprisingly, the man responsible for one of the most progressive green-design competitions has doubts about ideas of eco-friendly buildings. “I don’t believe in the new green religion,” Gerner says. “Some of the building technologies that you get are impractical. I’m interested in those that work.” But he wouldn’t mind if some green features inspire students. He says he hopes to set up green energy systems that allow them to learn about the process of harvesting wind and solar power. “You never know what’s going to start the interest of a child to study math and science,” he says.

1.How did the architects react to Gerner’s design requirements?

A. They lost balance in excitement.             B. They showed strong disbelief.

C. They expressed little interest.              D. They burst into cheers.

2.Which order of steps is followed in carrying out the project?

A. Assessment — Prototype — Design — Construction.

B. Assessment — Design — Prototype — Construction.

C. Design — Assessment — Prototype — Construction.

D. Design — Prototype — Assessment — Construction.

3.What makes it difficult to build green schools in Clark County?

A. The large size.                          B. Limited facilities.

C. The desert climate.                      D. Poor natural resources.

4.What does Gerner think of the ideas of green schools?

A. They are questionable.                   B. They are out of date.

C. They are advanced.                       D. They are practical.
