The fact that over 1.24 million people lose their lives each year in road accidents is a horrifying statistic that could soon be prevented. It should be of no surprise to understand that the autonomous vehicle industry is predicted to be worth $2.6 trillion a year within 15 years.
What's the future of personal transportation? Well, you'll likely be spending a lot less time behind the wheel, for one. The rise of self-driving cars means that some scenes out of science-fiction flicks（电影）（think Total Recall or I, Robot）are now reality—and even more will be available soon.
Cars today already include many semi-autonomous features, like assisted parking and self-braking systems. And completely autonomous vehicles—able to operate without human control—are rapidly becoming more of a reality. You're probably familiar with Google's version, which has made headlines with its Google Chauffeur software, which the company hopes to bring to market by 2020.
The pros of autonomous cars are many. "The sensors in a self-driving car are always observing, are not affected by the state of the driver（sleepy, angry, etc.）, and can scan in multiple directions simultaneously（同时地）," says Dr. Dominique Freckmann, an automotive engineering manager at TE Connectivity, "Autonomous driving is a key aspect of the industry's drive toward safer roadways."
"Recent NHTSA research shows that approximately 94 percent of accidents are caused by human error," adds Alan Amici, a vice president of automotive engineering at TE. "Cars with advanced safety features and eventually, self-driving cars, can significantly reduce the number of collisions. The impact of this innovation can be far-reaching, including reduced demand on emergency response systems and reduced auto insurance and health care costs."
1.What is the author's attitude towards the autonomous vehicle industry?
A.Positive. B.Disapproving.
C.Uncaring. D.Doubtful.
2.Why is Google Chauffeur software given as an example here?
A.Because people believe Google will sell it in 2020.
B.Because it is the most famous software of the company.
C.Because people are all familiar with the famous software.
D.Because it shows completely autonomous vehicles will be true.
3.Which is the main reason why Alan Amici favors self-driving?
A.Self-driving will cost less than now.
B.People will easily save a lot of time.
C.Self-driving will be safer than now.
D.People will rely more on auto insurance.
4.What is the author's purpose of writing the text?
A.To show his adoration of self-driving cars.
B.To predict the future of personal transportation.
C.To prevent so many road accidents caused by driving.
D.To introduce the benefits of autonomous vehicle industry.

People You’ve Never Heard of Who Changed the World
It is a fact that most people live their lives unremarked by history. Whether by design or by accident, there are some pioneers whose achievements changed the course of history but whose names are unknown to us.
James Harrison
James Harrison has saved the lives of over two million people by donating his blood 1,173 times, a Guinness world record. His blood produces a rare antibody (抗体) which cures the otherwise deadly Rhesus disease in unborn children. It has also been used in the development of a medicine anti-D, which will cure the Rhesus disease in children forever.
Lewis Latimer
After helping Alexander Graham Bell obtain his patent for the telephone, Lewis Latimer patented a carbon filament (碳灯丝), which allowed light bulbs to burn for hours before burning out, much more useful than that invented by Thomas Edison. Latimer went on to invent many other useful devices, including a device which cooled and cleaned patients’ rooms in hospitals.
Maurice Hilleman
Not all achievements require bravery and self-sacrifice. Take Maurice Hilleman for example. He found another way to change the world. He developed the mumps vaccine (疫苗) after his daughter got the illness. And he didn’t stop there. In total, he has single-handedly developed over 40 vaccines, including eight commonly given to children. His work has saved millions of lives and prevented serious consequences due to the diseases.
Nils Bohlin
In 1959 Nils Bohlin patented a revolutionary design that has saved millions of lives － the three-point safety belt. After the initial resistance from drivers who hated being told what to do, and even for their own good, the three-point belt has become a standard feature in new cars around the world.
1.Whose patent allowed light bulbs to burn for hours before burning out?
A. Alexander Graham Bell. B. Lewis Latimer.
C. Thomas Edison. D. Nils Bohlin.
2.What’s the similarity between James Harrison and Maurice Hilleman?
A. They both had spirits of bravery and self-sacrifice.
B. Their contributions saved the lives of many children.
C. They devoted themselves to work because of family members.
D. They both set a Guinness world record.
3.What was drivers’ initial attitude to the three-point seat belt?
A. They refused to use it. B. They were satisfied with it.
C. They were surprised at it. D. They got excited about it.

Homelessness is a huge problem all over the world. It’s said that each day there are about 1 million people living on the streets in the US. It is a serious problem which should be dealt with effectively.
There are two main reasons for people leaving their homes: poverty and less affordable houses due to bad economic conditions. Other reasons include: domestic violence, divorce, and mental illness. Living without a home makes people main targets of violence activities and besides, these homeless people have to face the following difficulties on a daily basis.
They have to move about, carrying their belongings, which makes it difficult for the charity and the government to help them. They have limited access to bathrooms and restrooms and are forced to live in dirty conditions, making them easy to be attacked by diseases. They have limited access to health-care facilities in case of emergency, and almost no access to education as they have no money. They are often ill-treated by society, which makes them unfriendly, often ending up being involved in activities connected with crime like selling drugs or guns.
Homelessness is not something that happened overnight --- it has been in the country for decades. The society usually believes those living on the street to be mentally unstable. This belief is partially true. Most of them are normal people just like you and me.
The federal government is doing all it can to help but it is not enough, so the ordinary citizens have to stand up and try to help whenever it’s possible. There are various organizations, such as charity organizations that are working constantly to make sure that homeless people find a shelter to live in. the united efforts have helped millions of people return to their normal lifestyle. However, there is still a long way to go before a better situation is created for all the homeless.
1.Homeless people suffer from all the following except __________.
A．violent activities B．disease attack C．moving a lot D．heavy work
2.The homeless are usually treated as __________.
A．having mental problems B．a danger to society
C．physically disabled people D．being too lazy to do anything
3.Which of the following are mentioned to help solve the problem of the homeless?

Millions of people around the world cook their food over smoky fire every day.It is often difficult to find wood for the fire .People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun.
Solar cooker, or ovens,have been used for centuries.A Swiss scientist made the first solar oven in seventeen sixty-seven. Today ,people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms.
There are three kinds of solar ovens.The first is a box cooker, It is designed with a special wall that shines or reflects sunlight into the box .Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amonts of food.
The second kind of solar oven is a panel cooker. It includes several flat walls.or panels.that directly reflect the sun’s light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much.In Kenya ,for example ,panel cookers are being manufactured for just two dollars.
The third kind of solar oven is a parabolic cooker.It has rounded walls that aim sunlight directly into the bottom of the oven .Food cooks quickly in parabolic ovens .However, these cookers are hard to make.They must be re-aimed often to follow the sun .Parabolic cookers can also cause burns and eye injuries if they are not used correctly.
You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at two hundred thirty-two degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.

高三英语阅读理解简单题查看答案及解析
Though the facts that too many people on earth and a too rapid increase in the number added each year are not in argument, we always begin the discussion of "population as global issue" with what most persons mean like this. It was quite right to compare demographic growth to "a long, thin powder fuse(导火线)that bums steadily and hesitatingly until it finally reaches the charge and explodes".
To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility(生育)in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.
This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden
enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.
Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8000 B.C. till approximately 1650 A.D. In the first period of some 9,600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and 1975, the population has increased from 500 million to more than 4 billion. And the population reached 6.2 billion throughout the world by the year 2000, One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000 B.C. and 1650, an average of only 50,000 persons was being added annually to the world's population, At present, this number is added every six hours. The increase is about 800000,000 persons annually.
1.The underlined word "demographic" in Paragraph l means .
A. extinction of human
B. statistics of human population
C. death rate of human
D. development of human population
2.Which of the following demographic growth patterns is most similar to the long thin powder fuse?
A. A slow growth for a long time and then a period of rapid, dramatic increase.
B. Too many people on earth and a few rapid increases in the number added each year.
C. A virtually stable or slightly decreasing period and then a sudden explosion of population.
D. A long period when death rates exceed birthrates and then a short period with higher fertility and lower mortality.
3. During the first period of demographic history, societies were often in danger of extinction because .
A. only one in ten persons could live past 40.
B. our ancestors had little enthusiasm for more children
C. there was higher mortality than fertility in most places
D. it was too dangerous to have babies due to the poor conditions
4.The author of the passage intends to .
A. warn people against the population explosion in the near future
B. find out the cause of rapid increase in population in recent years
C. present us a brief and clear picture of the demographic growth
D. compare the demographic growth pattern in the past with that after 1650
