26、 There were many beautiful buildings in ancient Rome, but the living conditions for ordinary people were bad. Most of their homes were so poorly made that they fell down or were fire hazards (danger) with their steep, narrow wooden stairways. Most people were packed into apartment buildings that rose shakily (unsafely) six to twelve floors above the ground. The apartments were rooms about three metres square, and each building housed about five hundred people.
These tall buildings faced each other across streets only three metres wide, so no sunlight reached the ground. Even so, apartments were costly, though cheaper places could be found outside Rome. But people wanted to be near their work and entertainment. So the streets became crowded and it was hard to move quickly. At night, the streets were filled with noise as food and supplies were brought into the city on wagons and carts.

27、I'll never forget the day when Mary came into my office and said, I am too old to learn how to use a computer. I shook my head. Here was a woman who had raised 6 children and who had made great progress in her career telling me that she was too old to learn something new. I told her that I always believed people were never too old to learn.
Mary followed my advice and did learn how to use the computer. Now, she is retired and leading a very active life volunteering in her community( 社区 ),using her computer skills and helping anyone that needs help.
When she was in her sixties, one day she called me and said she had played the piano for others all her life, and now she was going to make a CD of her own. My mind flashed back to the day when she told me she was too old to learn. You can imagine my surprise and delight.
To produce the CD, she had a lot of things to learn. It was not just sitting at the piano and playing. She had to research the songs, learn about copyright(版权),and learn about marketing. It was pretty amazing for someone who once said she was too old to learn. And finally she made it. Now she has her own CD-Mixed Blessings.
Most of you probably have heard about some people who have gone back to university in their seventies and have also graduated. They are on their way again to charging themselves with a new skill and a new attitude towards life. The point is you are unable to learn anything at any age if you believe you are too old. On the contrary, you can achieve anything at any age if you believe you can.

29、Teens and their teachers know well that early-morning classes can be tiring. Doctors now have a solution: for better teen health, push the sleep button on school start times. Janet Croft, who studies teens and sleep at the Centers for Disease Control and
Prevention(CDC)in Atlanta high schools, says, “Most teens are actually brain dead when they go to these early classes. Too many students start their day as walking zombies(僵尸).”
One report stresses the importance of sleep for teens and describes the dangers from not getting enough sleep. Studies in the past have shown over and over that teens lacking sleep face higher risks of being overweight and being frustrated.
Many teens get too little sleep because they attend middle and high schools that start earlier than 8:30 am. According to the American Academy of Pediatrics(AAP),those early start times throw off a student’s internal body rhythm, called the circadian clock(生物钟).Too little sleep disturbs that clock and causes problems.
The study conducted by the National Sleep Foundation found that nearly 6 in every 10 middle school students and 9 in 10 high school students are sleeping too little. Yet many parents aren’t aware of this. In the same study,7 of every 10 parents said they believed their kids did sleep enough. That study shows too many parents are unaware of the science on teen-sleep needs, says Owens.
Kyla Wahlstrom, a former teacher, who has spent a lot of time with teens lacking sleep, says: “An incredible number of students are either sleeping at their desks or sitting there like a lump, not asking questions or raising their hands.”
Getting enough sleep can help a teen on the inside, too. Several studies have shown that children and teenagers who don’t sleep enough are more likely to become obese, or extremely overweight. Teens lacking sleep also are more likely to suffer from anxiety, depression and mood disorders. It’s time to recognize how important sleep is, particularly to teenagers.
【1】What does the author want to stress by mentioning “walking zombies” in Paragraph 2?
A．The students’ brain health is worrying.
B．The students are fond of computer games.
C．The students are so used to staying up very late.
D．The students are in a bad state of learning in early classes.
【2】According to AAP in Paragraph 4, early school schedules affect teens by
A．increasing their course load
B．affecting their circadian clock
C．affecting their performance at school
D．disturbing their relationships with classmates
【3】What can be inferred from the last paragraph?
A．The number of teens lacking sleep is growing fast.
B．Physical and mental health are equally important to teens.
C．It is really necessary to adjust school start times in the morning.
D．Teachers should take measures to raise students’ interest in learning.
【4】What’s the main idea of the text?
A．Parents are unaware of their kids’ sleep condition.
B．Being overweight is very common among American teens.
C．Early school start times can turn teens into the walking dead.
D．Researchers have found out how sleep is related to teens’ study.

Everyone has their own unique fingerprint; 【1】 makes fingerprints an ideal way to unlock smartphones. However, this may be 【2】 (safe) than we think.
Scientists at New York University and Michigan State University in the US have developed a set of fake fingerprints. They say that the prints 【3】 unlock any fingerprint-enabled smartphone up to 65 percent of the time.
The artificial fingerprints 【4】 (create) by using many common features found in human prints. They work 【5】 taking advantage of the way smartphone scanners check a fingerprint.
The fingerprint scanners 【6】 (use) in smartphones are so small that they only read parts of fingerprints. So they have to take many scans of your finger or thumb (拇指) 【7】 they work properly. Smartphones also let users save several finger and thumbprints. Since a print only has to match one of the saved images 【8】 (unlock) the phone, the scanner is more likely to make mistakes.
Although the scientists have only tested their findings in computer simulations (模拟), 【9】 (worry) about the safety of using fingerprints are reasonable .They warn that the technology used to create artificial fingerprints is improving 【10】 (extreme) fast.

Why Cold weather Causes So many Flight Cancellation?
Each year, about 60,000 flights get canceled because of bad winter weather, which costs airlines and airports an estimated $3 billion. But it’s not the freezing cold temperatures that cause problems for planes. After all, 【1】 jets fly 10 kilometers up, where temperatures hover around -50 degrees Celsius.
In fact, planes 【2】 in cold weather, since cold air is denser and leads to better thrust. Clearly, the real problem isn’t what’s going on up there. It’s what’s happening on the ground.
When a 【3】 polar vortex (极地涡旋) struck the Midwestern US in January 2019, temperatures dropped to -40 degrees Celsius and airline canceled 3,000 flights nationwide. In these situations, when temperatures start 【4】, everything slows down. Cargo doors can freeze up, along with the nozzles that pump fuel into planes, which delays the 【5】 process.
Even the plane itself can freeze over. Just a quarter-inch - thick layer of ice on a plane can disrupt the way air flows over its wings.
Les Westbrooks: The number one reason, I would say, that the reason flights get delayed in cold weather is going to be because there’s some kind of frozen precipitation, from frost to snow to a sheet of ice, adhering to the aircraft, adhering to the wings of the aircraft 【6】.
That’s Les Westbrooks, a retired airline pilot and an associate professor of aeronautical science at Embry-Riddle Aeronautical University. He says that 【7】, these planes are “de-iced” - but this also delays takeoff. The crew can spray the plane with a special hot water/ glycol mixture. It can take around 40 minutes to de-ice large passenger airplanes, so planes often have to wait “their turn” for the de-icing station, which, of course, can trigger more delays.
And ice on the runway, of course, creates another set of 【8】. In 2014, a plane at JFK skidded off an icy runway and into a mound of snow, leading to an hours-long shutdown at the airport. And even though crews can remove ice from the runway, scraping it off the pavement can lead to potholes (坑洞) and other 【9】, which makes takeoffs and landings more dangerous. And of course, snow and freezing rain on the ground can affect visibility to the point where officials have to decide it’s not safe to fly at all.
But if ice and snow aren’t the problem in these extremely cold temperatures, it’s usually another factor: people.
Les Westbrooks: The airplane flies at high altitudes, -60 degrees. It’s made to do that. Humans are not made to be outside in -60 degrees weather. And so the human factor becomes a big, big factor, when it becomes extremely cold.
Baggage handlers, aircraft fuelers, and mechanics all have to stay warm. Some airports, like O’Hare in Chicago, set up heated shelters for their employees. Of course, with everyone taking breaks to warm up, not as much gets done, which leads to even more delays and cancellations. Passengers start missing their 【10】 flights, and that, along with passengers who can’t make it to the airport due to bad road conditions, leads to half-empty planes.
In fact, many airlines might preemptively cancel flights before bad weather even hits. So, in the end, you can still blame cold weather for cancelling your flight.

Knowledge is free on the Internet at a small but 【1】 number of colleges and universities. About 160 schools around the world now put free course materials on the web to the 【2】. Recent additions in the United States 【3】 projects at Yale, Johns Hopkins and the University of California, Berkeley.
Berkeley said it would offer videos of lectures on YouTube. Free videos from other schools are 【4】 at the Apple iTunes store.
The Massachusetts Institute of Technology (MIT) became an early 【5】 with its Open Course Ware project, first 【6】 in 2001. Free lecture notes, exams and other resources are published at ocw.mit.edu. Many exams even include the answers. Today, Open Course Ware offers materials from 1,800 undergraduate and graduate courses. These 【7】 from Physics to Political Science. Visitors can learn the same things as MIT students learn. But as the site points out, Open Course Ware is not an MIT education. Visitors receive no credit toward a degree.
