Travelling at speed has always been dangerous.One advanced area of research in motoring safety is the use of digital in-car assistants.They can ensure you don't miss important road signs or fall asleep .Most crashes result from human and not mechanical faults.
Some safety developments aim to improve your vision.Radar can spot obstacles in fog,while other technology"sees through"big vehicles blocking your view.

参考答案
参考解析
解析：本题的答案在第一段第二句话“much research now is focused on safety and new fu-els"，所以正确答案是D，改善汽车的安全和发展新型燃料。
第二段最后一句话明确指出“most crashes result from human and not mechanical faults"，选项B中human mistakes即human faults.
选项B和C的内容在文中第三段提到“Radar can spot obstacles in fog , while other technology ‘ sees through ’ big vehicles blocking your view”，选项D在第四段中第一句话 提到“...improvements to seat belts,pedal controls and tyres are making driving smoother and safer.”只有选项A未被提及。
本题的答案可以直接从第五段倒数第一句话中找到“Satellite tracking and remote communications can also came into play if you crash , automatically calling for help.”这里 come into play是开始起作用的意思。
文章最后一句话指出机器人司机可以使交通运行更通畅，也许有一天机器人会成为每个人的私人司机，但是最近的研究表明这个愿望不会很快实现，这正是选项A所 表达的意思“It will take some time before robotic drivers are available.”其他三个选项的内容文章根本就没有提及。

In 2007,M Corporation paid dividends totaling$3 million on net income of$15 million. 2007 was a normal year,and for the past five years,earnings have grown at a constant rate of 10 percent. However,earnings are expected to jump to$18 million in 2008,and the firm expects to have$12 million investment opportunities in 2009. It is predicted that M will not be able to maintain the 2008 level of earnings growth in the future——the high 2008 earnings level is attributable to an exceptionally profitable new product line introduced in that year—and the company will return to its previous 10 percent growth rate. M's target debt ratio is 40 percent in 2007,which will be continued in the future.
Requirment：
Calculate M's expected dividends for 2008 if it follows each of the following policies:
A.Its 2008 dividend payment is set to make dividends grow at the long-run growth rate in earnings.
B.It continues the 2007 dividend payout ratio.
C.It uses a residual policy with all distributions in the form of dividends.
D.It employs a regular-dividend-plus-extras policy, with the regular dividend being based on the long-run growth rate and the extra dividend being set according to the residual policy (Indicate the regular dividend and the extra dividend separately).

Deaths Associated with Sugary Soft DrinksSugar-sweetened sodas,sports drinks and fruit drinks may be associated with about 180,000 deaths around the world each year,according to a recent research.Sugar-sweetened beverages are consumed throughout the world,and contribute to excess body weight,which increases the risk of developing diabetes,cardiovascular diseases and some cancers. Using data collected as part of the 2010 Global Burden of Diseases Study,the researchers linked intake of sugar-sweetened beverages to 133,,000 diabetes deaths,44,000 deaths from cardiovascular diseases and 6,000 cancer deaths.Seventy-eight percent of these deaths due to over-consuming sugary drinks were in low and middle-income countries,rather than high-income countries."In the U.S.,our research shows that about 25,000 deaths in 2010 were linked to drinking sugar-sweetened beverages,"said Mr. Singh,a postdoctoral research fellow at the Harvard School of Public Health in Boston.Of nine world regions,Latin America/Caribbean had the most diabetes deaths(38,000)related to the consumption of sugar-sweetened beverages in 2010.Japan,one of the countries with lowest per-capita consumption of sugary beverages in the world,had the lowest death rate associated with the consumption of sugary beverages,at about 10 deaths due to per million adults."Because we were focused on deaths due to chronic diseases,our study focused on adults.Future research should assess the amount of sugary beverage consumption in children across the world and how this affects their current and future health,"Singh said.The American Heart Association recommends adults consume no more than 450 calories per week,from sugar-sweetened beverages,based on a 2,000 calorie diet and offers tips to help you make better lifestyle choices and eat healthier.Korea had the lowest death rate associated with the consumption of sugary beverages.A:Right B:Wrong C:Not mentioned

第三篇Global Cancer Rates to Rise by 50% by 2020The number of new cancer cases worldwide is expected to increase by 50%by the year 2020.But a new report suggests that as many as a third of new cancers could be avoided by adopting healthier lifestyles and through public health action.The World Cancer Report,released by the International Agency for Research on Cancer,shows that cancer has now emerged as a major public health threat in developing countries as well as rich ones.Overall,cancer was responsible for 12%of all deaths in 2000.But in many countries more than a quarter of all deaths are caused by cancer.The report shows that 1 0 million new cancers were diagnosed globally in 2000,and that number is expected to rise to 15 million by 2020.Researchers say most of that increase will mainly be due to steadily aging populations in both developed and developing countries and current trends in smoking and other unhealthy habits."Cancer has emerged as a major public health problem in developing countries for the first time, matching its effect in industrialized（工业化的）countries , " said researcher Paul Kleihues,MD,director of IARC,in a news release."Once considered a'Western' disease,the Report highlights that more than 50 percent of the world's cancer burden,in terms of both numbers of cases and deaths,already occurs in developing countries."The risk of being diagnosed with cancer in developed countries is double that in less-developed ones.However,the risk of dying from cancer is much higher in developing countries , where 80% of cancer patients already have late-stage incurable tumors（肿瘤） at the time of diagnosis.Researchers say cancer rates have traditionally been higher in developed countries due to greater exposure to tobacco,occupational carcinogens（致癌物）,and an unhealthy Western diet and lifestyle.As less-developed countries become industrialized and more prosperous,they tend to adopt the high-fat diet and low physical activity levels typically seen in the West,which increase cancer rates. The report says that steps could be taken to reduce aboutA:50% of new cancers. B:33% of new cancers.C:12% of new cancers. D:80% of new cancers.

第三篇Global Cancer Rates to Rise by 50% by 2020The number of new cancer cases worldwide is expected to increase by 50%by the year 2020.But a new report suggests that as many as a third of new cancers could be avoided by adopting healthier lifestyles and through public health action.The World Cancer Report,released by the International Agency for Research on Cancer,shows that cancer has now emerged as a major public health threat in developing countries as well as rich ones.Overall,cancer was responsible for 12%of all deaths in 2000.But in many countries more than a quarter of all deaths are caused by cancer.The report shows that 1 0 million new cancers were diagnosed globally in 2000,and that number is expected to rise to 15 million by 2020.Researchers say most of that increase will mainly be due to steadily aging populations in both developed and developing countries and current trends in smoking and other unhealthy habits."Cancer has emerged as a major public health problem in developing countries for the first time, matching its effect in industrialized（工业化的）countries , " said researcher Paul Kleihues,MD,director of IARC,in a news release."Once considered a'Western' disease,the Report highlights that more than 50 percent of the world's cancer burden,in terms of both numbers of cases and deaths,already occurs in developing countries."The risk of being diagnosed with cancer in developed countries is double that in less-developed ones.However,the risk of dying from cancer is much higher in developing countries , where 80% of cancer patients already have late-stage incurable tumors（肿瘤） at the time of diagnosis.Researchers say cancer rates have traditionally been higher in developed countries due to greater exposure to tobacco,occupational carcinogens（致癌物）,and an unhealthy Western diet and lifestyle.As less-developed countries become industrialized and more prosperous,they tend to adopt the high-fat diet and low physical activity levels typically seen in the West,which increase cancer rates. The risk of dying from cancer in developed countries isA:double that in developing countries.B:much higher than that in developing countries.C:the same as that in developing countries.D:much lower than that in developing countries.

Deaths Associated with Sugary Soft DrinksSugar-sweetened sodas,sports drinks and fruit drinks may be associated with about 180,000 deaths around the world each year,according to a recent research.Sugar-sweetened beverages are consumed throughout the world,and contribute to excess body weight,which increases the risk of developing diabetes,cardiovascular diseases and some cancers. Using data collected as part of the 2010 Global Burden of Diseases Study,the researchers linked intake of sugar-sweetened beverages to 133,,000 diabetes deaths,44,000 deaths from cardiovascular diseases and 6,000 cancer deaths.Seventy-eight percent of these deaths due to over-consuming sugary drinks were in low and middle-income countries,rather than high-income countries."In the U.S.,our research shows that about 25,000 deaths in 2010 were linked to drinking sugar-sweetened beverages,"said Mr. Singh,a postdoctoral research fellow at the Harvard School of Public Health in Boston.Of nine world regions,Latin America/Caribbean had the most diabetes deaths(38,000)related to the consumption of sugar-sweetened beverages in 2010.Japan,one of the countries with lowest per-capita consumption of sugary beverages in the world,had the lowest death rate associated with the consumption of sugary beverages,at about 10 deaths due to per million adults."Because we were focused on deaths due to chronic diseases,our study focused on adults.Future research should assess the amount of sugary beverage consumption in children across the world and how this affects their current and future health,"Singh said.The American Heart Association recommends adults consume no more than 450 calories per week,from sugar-sweetened beverages,based on a 2,000 calorie diet and offers tips to help you make better lifestyle choices and eat healthier.Intake of sugar-sweetened beverages may link to high blood pressure.A:Right B:Wrong C:Not mentioned

Breast Cancer Deaths Record LowThe number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a year for the first time since records began.The Cancer Research UK data showed that 11,990 women died in the UK in 2007.The previous lowest figure had been recorded in 1 97 1一 the year records began一after which it rose steadily year by year until the late 1980s.Professor Peter Johnson,Cancer Research UK's chief clinician,said,"It's incredibly encouraging to see fewer women dying from breast cancer now than at any time in the last 40 years,despite breast cancer being diagnosed more often.""Research has played a crucial role in this progress,leading to improved treatments and better management for women with the disease."" The introduction of the NHS（国民保健制度）breast screening program has also contributed as the earlier cancer is diagnosed,women are more likely to survive."Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease一a 50% rise in 25 years.The number of deaths peaked in 1989,when 15,625 women died.It then fell by between 200 and 400 deaths each year until 2004.There was a slight rise in 2005 and then two years of falls.Dr. Sarah Cant,policy manager at Breakthrough Breast Cancer,said,"It is great news that fewer women are dying from breast cancer and highlights the impact of improved treatments,breast screening and awareness of the disease.""However,there are still too many women affected and the incidence of the disease is increasing year byyear.,,The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity （肥胖）and alcohol consumption.Obesity and alcohol consumption may also lead to some other diseases.A:RightB:WrongC:Not mentioned
