but a faster network loads Web pages more quickly, true GPS functionality allows it to easily
find places nearby, and the new $199 price (down from $400) makes it an affordable luxury.
Before deciding whether to buy, however, make sure you can actually take advantage of
the iPhone 3G"s high-speed data network. 3G stands for third-generation, which in non-geek
speak translates to Web pages and mail messages that, ideally, load about three times faster
than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf
the Web at the same time. That"s great, if you live or work in a place where the 3G network of
AT&T (美国电话电报公司) (the sole wireless carrier of the iPhone) is active. That"s not so
great in cities like New York where AT&T"s cellular coverage is awful. As one of my colleagues
in New York City, who bought the original iPhone, commented, "It"s just a toy. You can"t make
phone calls on it, so I carry my Verizon phone with me all the time."
The real fun begins when you tap on the icon called "App Store" and start browsing the hundreds
of add-on applications that have been developed just for the iPhone. You"ll find tons of games (I like
JirboBreak, a free game inspired by the Atari classic Breakout) and mobile versions of popular
websites like Pandora, Facebook, MySpace and the New York Times. Most apps will cost you,
but the vast majority are $9.99 or less. The apps work on the old iPhones too, but you"ll enjoy them
a lot more on the iPhone 3G because many of the programs, including Yelp (local business reviews),
Whrrl (mobile social networking) and UrbanSpoon (restaurant reviews), use your exact location-
provided by the iPhone 3G"s GPS chip-to make recommendations. The apps also load much faster
over the 3G network.
B. It has a faster network
C. It is easy to locate a place
D. It is too expensive for people to buy
B. ecause he prefers Verizon phone better.
C. Because AT&T"s cellular coverage is terrible there.
D. Because Verizon phone enables him make a phone call and surf the Web at the same time.
B. many apps have been developed for the iPhone.
C. Most apps are very expensive.
D. Pandora, Facebook, MySpace and the New York Times are popular websites.
B. appreciative
C. optimistic
D. pessimistic

sleeping-control which side of the brain remains awake, according to a new study of
sleeping ducks.
Earlier studies have documented half-brain sleep in a wide range of birds. The brain
hemispheres take turns sinking into the sleep stage characterized by slow brain waves.
The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere"s
eye stays open and alert. Birds also can sleep with both hemispheres resting at once.
Decades of studies of bird groups led researchers to predict extra alertness in the
end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds
tended to watch carefully on the side away from their companions. Ducks in the inner spots
showed no preference for gaze direction.
Also, birds napping at the end of the line depend on single-hemisphere sleep, rather
than total relaxation, more often than inner ducks did. Turning 16 birds through the
positions in a four-duck row, the researchers found that compared with 12 percent for
birds in internal spots, outer birds half-asleep during some 32 percent of napping time.
"We believe this is the first evidence for an animal behaviorally controlling sleep
and wakefulness at the same time in different regions of the brain," the researchers say.
The results provide the best evidence for a long-standing assumption that single-
hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an
eye on the lookout side could be widespread, he predicts. He"s seen it in a pair of birds
napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror
-side eye closed as if the reflection were a companion and the other eye stayed open.
Useful as half-sleeping might be, it"s only been found in birds and such water animals
as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a
sleeping animal to surface occasionally to avoid drowning.
Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA
says he wonders if birds" half-brain sleep "is just the tip of the iceberg." He
supposes that more examples may turn up when we take a closer look at other species.
B. their brain hemispheres take turns to rest
C. the two halves of their brain are differently structured
D. they have to constantly keep an eye on their companions
B. Birds prefer to sleep in pairs for the sake of their security.
C. The phenomenon of birds napping in pairs is widespread.
D. A single pet bird enjoys seeing its own reflection in the mirror.
B. emerge from water now and then to breathe
C. be sensitive to the ever-changing environment
D. avoid being swept away by rapid currents
B. the mystery of half-brain sleep is close to being solved
C. most birds living in cold regions tend to be half sleepers
D. half-brain sleep may exist among other species

| Can you remember a morning when you"ve woken up to the ring of your alarm clock and wished you could stay in bed? You haven"t slept well, your hair is a mess. Worse, you can"t stop yawning. Yawning is universal to humans and many animals. Cats, dogs and fish yawn just like humans do! Yawning is an involuntary (无意识的,不自觉的) action during which you open your mouth and breathe deeply. The average duration of a yawn is about 6 seconds. The purpose and cause of yawning are still a mystery. Scientists are not sure what causes a yawn. People yawn when they are tired or bored, but they also yawn when they aren"t. There are many ideas explaining why we yawn. One idea is that yawning is a way for the body to become more alert by taking in more oxygen. A yawn increases the heart rate, forces carbon dioxide out of the lungs and blood stream, and brings oxygen to the brain. But one study showed that volunteers given a lot of oxygen did not yawn any less than before, while those given a lot of carbon dioxide did not yawn more. Another idea is that early humans used yawning as a form of communication. If one decided it was time to sleep, they would tell the others by yawning and they would do it in return to show they agreed. A third explanation comes from psychology professor Gordon Gallup of University at Albany in New York. He said that as people yawn, they cool off their brains. "Brains are like computers." he said. "They only operate efficiently and effectively when they"re cool. Many things connected to yawning, like being tired, make the brain hot, and yawning can reduce the heat." Scientists have sent people into space, and created terrible nuclear weapons, but there are lots of seemingly simple things, such as why we yawn, or hiccup, that they can"t figure out. Next time you are in class in the morning, let out a big yawn and watch to see how many of your classmates yawn in response! | |

| Electronic monitoring devices, mobile phone detectors and giant screens connected to close-circuit TV cameras. Does it sound like a high security operation? Well, the National College Entrance Examination (NCEE) in China is nothing less than that. The education authorities" efforts to prevent cheating at the exam have gone almost unnoticed. The authorities launched the country"s new monitoring system for the all- important exam yesterday. The system is based on local schools" networks and is connected to provincial headquarters, especially set up for the exam. The government has plans to cover all the 31 provinces and regions in the next three years and offer the services for other national exams, too. The records of students caught cheating during national tests, such as the college entrance exam, would be stored in the system and made available online for higher educational institutions" and future employers" reference. But despite all these measures, cheating remains a big temptation for some candidates. The number of students caught cheating in last year"s NCEE was 3,000, up from 1,300 in 2005. But this is hardly surprising because passing the NCEE is the only way most of the students can get access to higher education. 10.1 million students registered for this year"s NCEE, 9.6 million taking the exam, but only 5.67 million would enter college. Among the successful candidates will be about 500,000 with special merits who will be admitted to universities directly, which means roughly 13 in every 24 candidates can actually enter college. That should explain why some students are tempted to cheat during the exam. Cheating in such a well-monitored exam is not an easy thing to do, says an MOE official, and it"s very risky business too. The chance of a student getting away with cheating is minuscule. And if caught, he/she risks ruining his/her entire career because higher educational institutions and potential employers can always check his/her record. | |
| 1. The passage is most probably taken from _____. | |
| [ ] | |
| A. a politics textbook. B. a fashion report. C. a reference book. D. a newspaper. | |
| 2. According to the passage, what will happen if a student is caught cheating in the NCEE? | |
| [ ] | |
| A. He/She will lose the chance to sit for more exams. B. His/Her behavior will be recorded, stored and made available online. C. He/She will get no records and lose the opportunity to go to college. D. He/She will be blamed and his/her career and life will be put an end to. | |
| 3. The underlined word"minuscule" in the last paragraph probably means _____. | |
| [ ] | |
| A. tiny B. impossible C. difficult D. incredible | |
| 4. We can draw a conclusion from the passage that _____. | |
| [ ] | |
| A. the education authorities are making great efforts to prevent cheating in exams B. although it is very hard to succeed, many students take a chance to cheat in exams C. honesty is still the best policy when it comes to exams D. it is not easy to get access to higher education in China | |
