A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度) of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.
The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.
They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76. 6 fewer accidents will occur per month or 917 fewer accidents per year.
Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.
“We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we’ re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors explained Prof Ho.
1.Why do yellow taxis result in fewer accidents?
A. Because yellow signals a warning of danger.
B. Because yellow can be seen more easily.
C. Because drivers tend to he more careful in yellow taxis.
D. Because people act more quickly in yellow surroundings.
2.What’ s Prof Ho’s study based on?
A. Physical risks taxi passengers experience.
B. The economic effect of changing taxi color.
C. Personal reports from taxi drivers worldwide.
D. Data from Singapore's largest taxi company.
3.What do Prof Ho’s words in the last paragraph suggest?
A. School buses should be painted yellow.
B. Their findings are worth popularizing.
C. Their study will be furthered.
D. Yellow should be widely used in public transport,
4.What can be the best title for the text?
A. Safer to ride in yellow taxis B. Caution: yellow taxis ahead
C. Why are yellow Taxis preferred? D. How can colors help prevent accidents?

A recent study conducted by researchers from Canada's Wilfrid Laurier University found that the snakes actively seek out socialization with their peers (同伴),but also they are extremely particular about who they spend time with. However, snakes used to be thought of as solitary animals. They are seldom seen hanging out in groups.
A team of researchers led by Morgan Skinner and Dr. Noam Miller selected 40 non-poisonous garter snakes (袜带蛇). Ten were purchased from a snake keeper and the rest were caught in the wild. After marking each snake with a spot of color to allow for easy identification, the researchers placed ten snakes inside each of the four plastic shelters.
Skinner photographed each snake group twice a day before removing them from their shelters. After cleaning the areas thoroughly to rid them of any familiar smells, the reptiles were rearranged into different groups, and returned to the enclosure. A camera fixed over the shelters allowed the scientists to track the animals' movements for a total of eight days.
When Skinner and Miller analyzed the images, they found that regardless of where they were placed, the snakes always slipped back to their origin al "friends" forming groups of three or eight inside the small shelters. “They can tell others apart,” Miller said.
Gordon Burghardt, a biologist, says, "The study should help convince people that snakes have more social intelligence than most of us realize."
Miller believes the research could help with snake protection efforts. Endangered snake species relocated to safer habitats often leave these areas. Now, conservationists may be able to avoid that by transferring entire snake groups to the new location. Alternatively, they could also spray (喷洒)the new habitat with the species' smells to make transplants feel at “home."
1.What does the underlined word "solitary" mean in paragraph 1?
A.Causing fear. B.Existing only in small numbers.
C.Causing death or illness. D.Enjoying being alone.
2.What can we learn from the last paragraph?
A.The findings can contribute to snake conservation.
B.Snakes like to spray smells on the trees.
C.Snakes are easy to adapt to new locations.
D.Snakes tend to stay in safer habitats.
3.Which of the following proverbs can be used to describe the findings?
A.Barking dogs don't bite. B.The early bird catches worms.
C.Things of one kind come together. D.A friend in need is a friend in deed.
4.In which section of a newspaper may this text appear?
A.Entertainment. B.Science.

A Robot Fish has been developed by National University of Singapore’s researchers from the Department of Electrical & Computer Engineering.This robot fish has movements which have been inspired by the movements of the carp(鲤鱼).
There are various purposes that it can be used for.It can help in underwater archaeology ( 考古学 ).For example, it can enter a sunken city where human divers cannot enter.Just like a fish , it can also look at all the comers of particular wreckage.This robot can also be used for general purposes such as detection of leakages in a pipeline or for laying down communication cables across oceans.It also has possible military uses.
In order to copy carp movements, Mr.Fan studied the movements of the fish for around 3 months.He studied all the different movements of carp using different cameras and then converted these movements mathematically to transfer this data to the robot using many actuators(驱动器).
Professor Xu commented on the robot that the current models that copy fish movements are capable only of 2D movements which limits their capability as they are not able to dive into water.He said that his model is the first model with 3D movements which allows it to dive as well as float with the help of its fins, just as a normal fish would do.Hence, this fish model robot has much greater movement capability.It would be much harder for enemies to detect as compared to traditional ones when used for military purposes.
The researches want to make their robot fish even smaller, more realistic while adding more sensors such as GPS and video camera to it.This will improve its autonomous 3D movement.They are also planning to test the fish by giving it more difficult tasks such as detecting various objects.
1.The author gave an example in paragraph 2 _____.
A.to introduce the Robot Fish can help in underwater archaeology
B.to show the Robot Fish can be used for general purposes
C.to show the Robot Fish can lay down communication cables across oceans

高二英语单项填空中等难度题查看答案及解析
The researchers, led by Hwang Woo-suk, insist they cloned an Afghan hound, only to help investigate (研究) human disease, including the possibility of cloning stem cells (干细胞) for treatment purposes.
But others immediately renewed calls for a global ban on human reproductive cloning before the technology moves any farther.
“Successful cloning of an increasing number of species confirms the general impression that it would be possible to clone any species of mammals, including humans,” said Ian Wilmut, a reproductive biologist at the University of Edinburgh who produced the first cloned mammal, Dolly the sheep, from an adult cell nearly a decade ago.
Researchers have since cloned cats, goats, cows, mice, pigs, rabbits, horses, deer, mules and gaur, a large wild ox of Southeast Asia. So far, efforts to clone a monkey or another primate with the same techniques have failed.
Uncertainties about the health and life span (寿命) of cloned animals continue to exsist; Dolly died at a young age in 2003 after developing cancer and arthritis.
Wilmut and others complimented Hwang’s achievement, reported Wednesday in the journal Nature. But they said politicians and scientists must face the larger issue — how to go on with the research without crossing the moral boundary of copying human life in the lab.
“The ability to use the technology is hopeful,” said Robert Schenken, president of the American Society for Reproductive Medicine. “However, the paper also points out that in dogs as in most species, cloning for reproductive purposes is unsafe.”
The cloned puppy was the lone success from more than 100 dogs implanted (嵌入)with more than 1,000 cloned embryos.
In a news conference in Seoul, the cloning team also condemned the reproductive cloning of humans as “unsafe and inefficient.” Human reproductive cloning already is banned in South Korea. Other nations, including the United States, are divided on whether to ban just human cloning or cloning of all kinds, including the production of stem cells.
1. An Afghan hound is a kind of ______.
A. cat B. dog C. cow D. goat
2. A ______ is a large wild ox of Southeast Asia.
A. horse B. deer C. mules D. gaur
3.Accrding to the passage, scientists haven’t been able to clone a ______ so far.
A. deer B. mule C. monkey D. mouse
4.The underlined word complimented is probably similar in meaning to ______.
A. praised B. doubted C. refused D. gave up
5.The cloning of human beings is banned in ______.

B. the United States
C. both South Korea and the United States
D. neither South Korea nor the United States

Researchers from the University of Newcastle are leading a worldfirst study which builds on earlier unpublished research that children are most likely to be guided by their father's eating and exercise habits.
The new study “Healthy Dads,Healthy Kids”,led by Associate Professor Philip Morgan from the University's Faculty of Education and Arts,is designed to help fathers promote and demonstrate to their children positive behaviors related to physical activity and healthy eating.
“The earlier findings showed that children are more likely to follow the example set by their father than their mother when it comes to eating and exercise,”said Morgan.Morgan saw striking results in a previous trial involving 165 overweight children.He found children who lost the most weight had fathers who were engaged in the new eating and exercise plan.
“We might think mothers are the main influence on children's diet and health,but the reality may be different,”said Morgan.“The roles of fathers are changing.More families have two parents working and more fathers are involved with food preparation and food shopping than in the past.”
“Fathers influence the food and physical activity habits in the home through their behaviours,attitudes and approach to food and eating,and act as a role model to their children,”said Morgan.
Researchers are inviting fathers who would like to reduce their weight to join the “Healthy Dads,Healthy Kids” program.Participation involves attending eight sessions (讲习班) at the University of Newcastle over six months where the men will receive information,have weightrelated measurements recorded and complete questionnaires.
Cooking healthy food with the kids and creating a backyard fitness circuit (循环训练场) are among the assignments (课外作业) for fathers taking part in the study.
1.What do we learn about the “Healthy Dads,Healthy Kids” program?
A.It aims to build close family relationships.
B.It involves fathers who want to lose weight.
C.It will last more than eight months.
D.It offers free online courses for parents.
2.Morgan finds a link between children's weight loss and .
A.their parents' efforts
B.their father's influence
C.balanced diets
D.regular sports training
3.Which of the following facts causes the change of fathers' roles?
A.That kids have more time to spend with family.
B.That more kids need their father's help in learning.
C.That there are more working mothers than before.
D.That fathers become much busier than before.
