A report, published in last week"s Journal of the American Medical Association, offers a picture of
how risky it is to get a lift from a teenage driver. Indeed, a l6-year-old driver with three or more passengers is three times as likely to have a fatal (致命) accident as a teenager driving alone. By contrast, the risk
of death for drivers between 30 and 59 decreases with each additional passenger.
The author also found that the death rates for teenage drivers increased dramatically after 10 p. m.,
and especially after midnight. With passengers in the car, the driver was even more likely to die in a
late-night accident.
Robert Foss, a scientist at the University of North Carolina Highway Safety Research Center, says
the higher death rates for teenage drivers have less to do with "really stupid behavior" than with just a
lack of driving experience. "The basic thing," he says, "is that adults who are responsible for issuing (发
放) licenses fail to recognize how skilled a task driving is."
Both he and the author of the study believe that the way to reduce the harm is to have so-called
graduated licensing systems,in which getting a license is a slower process. A graduated license requires
that a teenager first prove himself capable of driving in the presence of an adult, followed by a period of
driving at night with a limited number of passengers before graduating to get a full driving license.
Graduated licensing systems have reduced teenage driver crashes,according to recent studies. About
half of the states now have some sort of graduated licensing system in place, but only 10 of those states
have number limitation on passengers. California is the strictest, with a new driver prohibited from
carrying any passenger under 20 for the first six months. |

A. Adults giving a lift to teenagers on the highway after l0 p.m.
B. A teenager driving after midnight with passengers in the car.
C. Adults driving with three or more teenage passengers late at night.
D. A teenager getting a lift from a stranger on the highway at midnight. |
| 2. According to Robert Foss,the high death rate of teenage drivers is mainly due to ________. |

A. Teenagers should spend more time learning to drive.
B. Driving is a skill too difficult for teenagers to learn.
C. Teenagers should be limited in taking driving lessons.

Making them sweeter
JAPANESE scientists have developed a special kind of tomato. It can change an eater"s sense of
taste,says a report in Science News. For about an hour after a person eats one of the tomatoes,sour foods taste sweet.
Say you eat one of the tomatoes before lunch. Then you take a bite of a lemon (柠檬). You will
find that the lemon tastes like super-sweet lemonade.
How magical is that ! The key ingredient in the taste-changing tomatoes is " miraculin (非洲奇果蛋白 ) ". Miraculin is found in berries that grow in West Africa. These fruits are sometimes sold as "
Miracle(奇迹) Fruit" berries.
People have long known about the ability of miracle berries to change taste. In some countries,the
berries are used as a way to help people lose weight: For example,a dieter can eat a berry and then eat
low-calorie sour foods that will
taste wonderfully sweet.
Scientists found miraculin in the miracle berry in 1968. Since then,people have wondered how to
manufacture it. One way could be to harvest the berries. The problem was that if demand got too large,
the berry plants could be driven to extinction.
That"s where the Japanese scientists came in. Professor Kazuhisa Kato and his team at the University of Tsukuba studied the DNA of the miracle berry. They found a gene(基因) that contained the
instructions for how to make miraculin.
Kato and other researchers put the gene for miraculin into the DNA of a tomato. As a result,the
tomatoes started to make miraculin. Those tomatoes had just as much miraculin as miracle berries do.
These "miracle" tomatoes could be grown in large numbers. If scientists can grow other foods with
miraculin inside,then there won"t be any need to harvest all the miracle berries.
The researchers don"t know yet how the tomato-based miraculin can be used. Perhaps it could be sold as a dieting food,to be taken before meals. |
| 1. The tomato is special in that___. |
A. it tums all tastes sweet
B. it can only be eaten before lunch
C. it changes a sour taste to a sweet one
D. it has a magical ingredient |
| 2. According to the article,the Japanese scientists____. |
A. found a gene that contained instructions for making miraculin
B. discovered the secrets of miracle fruit berries in 1968
C. have planted miracle tomatoes in large numbers
D. invented the miraculin gene and put it into the tomato= |
| 3. According to the article,which of the following statements is TRUE? |
A. It was a latest discovery that miracle berries could change taste.
B. The tomato is a low-calorie fruit that tastes wonderfully sweet.
C. Scientists have already found many uses for mariculin.
D. The tomato-based miraculin might help people lose weight,so it might be used as a dieting food. |

MONTREAL (Reuters)-Crossing the US-Canada border (边界) to go to church on a Sunday cost a US citizen $10,000 for breaking Washington"s strict new security(安全) rules.The expensive trip to church was a surprise for Richard Al-bert, who lives right on the Canadian border. Like the other half-dozen
people of Township 15, crossing the border is a daily occurrence for Albert. The nearby Quebec village of St. Pamphile is where they shop, eat and go to church.
There are many such situations in these areas along the largely unguarded 5,530 mile border between
Canada and the US which in some cases actually runs down the middle of streets or throughbuildings.
As a result, Albert said he did not expect any problems three weeks ago when he returned home to the US after attending church in Canada, as usual. The US customs (海关) station in this area is closed on
Sundays, so he just drove around the locked gate, as he had done every weekend since the gate appeared last May, following a tightening of border security. Two days later, Albert was told to go to the customs
office, where an officer told him he had been caught on camera crossing the border illegally(非法).
Ottawa has given out special passes to some 300 US citizens in that area so they can enter the country when Canadian customs stations are closed, but the US stopped a similar program last May.That forces
the people to a 200 mile detour along hilly roads to get home through another border check point.
Albert has requested that the customs office change its decisions on the fine, but he has not attended a Sunday church since. "I feel like I"m living in a prison," he said. |
| 1. We learn from the text that Richard Albert is_______. |
A. an American living in Township 15
B. a Canadian living in a Quebec village
C. a Canadian working in a customs station
D. an American working in a Canadian church |
| 2. Albert was fined because he_______. |
A. failed to obey traffic rules
B. broke the American security rules
C. worked in St. Pamphile without a pass
D. damaged the gate of the customs office |
| 3. The underlined word " detour" in Paragraph 5 means______. |
A. a drive through the town
B. a race across the fields
C. a roundabout way of travelling
D. a journey in the mountain area |
| 4. What would be the best title for the text? |
A. A Cross-country Trip.
B. A Special Border Pass.
C. An Unguarded Border.
D. An Expensive Church Visit. |

LONDON ( Reuters) -Ecotourism (生态旅游) is causing a lot
of damage to wildlife and may be endangering the survival(生存) of
the very animals people are flocking to see,according to researchers.
Biologists and conservationists (自然环境持论者) are worried
because polar bears,dolphins, penguins and other creatures are
getting stressed and losing weight and some are dying.
"Evidence (证据) is growing that many animals do not react
well to tourists in their backyard,"New Scientist Magazine said.
The immediate effects researchers have noticed are changes in
behavior,heart rates,or stress hormone levels but they fear it could
get much worse and over the long term" could endanger the survival
of the very wildlife they want to see. "
Although money produced through ecotourism,which has been
growing at about 10 - 30 percent a year,has major benefits for poor
countries and people living in rural areas,the Swiss-based World
Conservation Union(IUCN) and some govemments fear not all projects
are audited (审查) and based on environmentally friendly policies,
according to the magazine.
"Transmission (传播) of disease to wildlife,or small changes
to wildlife health through disturbance of daily life or increased
stress levels,while not obvious to the casual observer,may translate
to lower survival and breeding," said Philip Seddon,of the University
of Otago in Dunedin,New Zealand.
Scientists have noticed that bottle-neck dolphins along the
northeastern coast of New Zealand become nervously excited when
tourist boats arrive. Similar changes in behavior have been observed
in polar bears and yellow-eyed penguins in areas visited by ecotourists
that are producing smaller babies.
Conservationists are now calling for more research into the
effect of ecotourism on animals and say the industry must be developed
carefully, They also want studies done before new ecotourism
projects are started.
"The animals" welfare should be very important because without
them there will be no ecotourism," said Rochelle Constantine of
the University of Auckland in New Zealand. |
| 1. What"s the theme of the text? |
A. Many animals are dying for lack of money.
B. There will be no ecotourism without animals.
C. Ecotourism could endanger the survival of the wildlife people want to see.
D. More research should be done on ecotourism. |
| 2. We may learn from the text that ____ . |
A. ecotourism must be developed properly
B. polar bears are losing weight without enough food
C. all the poor countries have stopped ecotourism
D. money produced through ecotourism should be spent on wild life |
| 3. Which of the following is NOT mentioned in the text? |
A. Many animals do not react well in their backyard.
B. Polar bears in areas visited by ecotourists are producing smaller babies.
C. Ecotourism has been growing at about 10 - 30 percent ayear.
D. Studies should be done before new ecotourism projects are started. |
| 4. What Rochelle Constantine said in the last paragraph implies that____． |

SAN FRANCISCO - In the western U.S., Hawaii and elsewhere across the globe, moon watchers
were treated Saturday to a rare celestial phenomenon: a total lunar eclipse (月全食).
For about 50 minutes starting at 6:06 a.m. PST, the moon was completely blocked by the Earth"s
shadow.
With only some indirect sunlight able to reach it after passing through the Earth"s atmosphere, the
moon took on a reddish glow. Since the atmosphere scatters blue light, only red light strikes the moon,
giving it a dark red color.
Dally Sam, who runs a public relations firm in Hawaii, said it had been cloudy and rainy, but the
weather cleared just in time for the eclipse.
Around 3 a.m., he awoke, as he usually does, and remembered to step outside the house in time to
catch the eclipse about a half hour later. No one else in the neighborhood was up.
"It was turning that dark red color," Sayre, 47, said, "I"d better grab a camera. To be able to see it
just right outside our house was really cool."
At the local observatory in Los Angeles, some 300 people, many clutching coffee cups in the cold
morning air, sat with blankets and chairs on the observatory"s great lawn.
"It"s really a celestial festival out here," John Peter, 39, told the Los Angeles Times as he set up his
camera.
Lying on a slope north of downtown near the Hollywood sign, the place offers clear views of the sky.
Observatory officials alerted the crowd when the eclipse began and spontaneous applause erupted when
the celestial event ended.
A total lunar eclipse occurs when the moon goes through the long shadow cast by the Earth and is
blocked from the sunlight that brightens it.
The last total lunar eclipse was on June 15 although that was not visible from the U.S. The next one is
on April 15, 2014, and will be seen in the U.S. |
| 1. What do we know about the lunar eclipse from the passage? |
A. The total lunar eclipse began at about 3:30 a.m.
B. The total lunar eclipse ended at about 6:56 a.m.
C. The lunar eclipse ended at about 6:56 in the evening.
D. The lunar eclipse began at about 6:06 in the evening. |
| 2. When a total lunar eclipse occurs, ________. |
A. the moon looks blue
B. the light will hurt our eyes
C. nothing of the moon can be seen except some dark red light around its place
D. another planet comes between the earth and the moon |
3. We can infer from paragraph 5 that at 3:30 a.m. Dally Sam ______.
A. found it was still raining heavily
B. saw a total lunar eclipse
C. went out walking as he usually does
D. still had to wait for a long time to see a total lunar eclipse |
| 4. From the last but one paragraph, the following are true EXCEPT _______. |
A. a total lunar eclipse occurs when the moon is blocked by the sun
B. the source of moonlight is from the sun
C. the earth comes between the moon and the sun
D. with the sunlight, the earth casts its shadow over the moon |
| 5. What is the main purpose of the passage? |
A. To inform us of the next total lunar eclipse.
B. To tell us about a rare celestial event.
C. To alert us of the natural disaster.
D. To draw people"s attention to the news. |
