Is there a limit to the number of years that a person can expect to live? Can changes in life-style add years to one’s life? Throughout history people have sought answers to these questions and others.
Various myths offer the hope of great longevity. In the imaginary land of Shangri-La, for example, people are said to lead a charmed existence for a thousand years. The Spanish explorer Ponce de Leon was convinced that he would find the Foundation of Youth in what is now the state of Florida. According to the Bible, Methuselah lived to be more than 900 years old.
The subject of longevity is fascinating, and scientists study individuals such as Jeanne Calment to learn about the aging process. Calment died in 1997 in Arles, France, at the age of 122. She never married, and she lived in her own apartment until moving to a retirement community when she was 109.
Most scientists agree that bodies will last, at best, about 125 years. This potential has changed little since modern human beings appeared more than 100 thousand years age. Recent improvements in medicine and the environment have extended life expectancy, especially for those from poorer parts of the world. It is not clear, however, whether such improvements will lengthen life expectancy beyond a certain point.
Life expectancy is the number of years an infant can be expected to live, given the conditions into which it is born. Life expectancy, therefore, is affected by nutrition, medical care, and social and political circumstances. An individual’s genetic makeup is also an important factor. Children from long-lived families can hope to enjoy long lives themselves. According to recent data, the average life expectancy worldwide in 1998 was 67 years. This can be compared with an average life expectancy of 77 in the United States.
In 1970 the average life expectancy worldwide was 61 years, or 6 years less than it was in 1998. This same period saw a drop in infant mortality -— the death of a child before the first birthday-—from 80 births out of 1,000 to 54 births out of 1,000. According to some researchers, the rise in the average life expectancy is due primarily to the drop in infant mortality. It is not so much that adults are living to an older age. It is, rather, that more people are living into adulthood because more children are surviving beyond their first birthdays.
1.Infant mortality is defined as ________ .
A. the number of children born alive
B. the kinds of behavior typical of very young children
C. the number of children, out of 1,000 births, who die before their first birthday
D. the typical and obvious thoughts of very young children
2.Although it may be possible to improve the life expectancy of a particular group of people, ________ .
A. it is more difficult to affect the rate of infant mortality
B. it is unlikely that one will be able to extend the potential life span of human beings in general
C. the process of evolution is extending the potential life span beyond 125 years
D. the potential that bodies will last, at best, about 125 years has changed much since modern human beings appeared
3.One can infer that people have at times imagined that ________ .
A. people live longer in the state of Florida
B. a long life is a burden rather than a blessing
C. it is possible to find a way to live for centuries
D. life expectancy is affected by a couple of factors
4.One can conclude that ________ .
A. the aging process can be stopped.
B. the aging process is inevitable.
C. life expectancy in the United States will soon reach 125 years.
D. the average life expectancy worldwide is decreasing

高三英语阅读理解中等难度题查看答案及解析
A person once told me that a quick way to know if you are in the right job is to count the number of good and bad days that you have at your current job. If the good days outweigh the bad days by a long shot, then you are probably in the right place.
While I like that as a quick test, it does not get at the heart of the matter. Is this the right job for me now and in the future? I think it takes time, introspection (内省) and willingness to ask yourself difficult questions to know if you are in the right job.
Here are a few suggested questions that can help you evaluate whether your current job is fit for you. How motivated are you to do the work every day? Are you passionate about the work? Do you feel you can make an impact? Are you learning and growing? Is the work challenging? Do you desire to take on more responsibility or be your manager one day? Do you enjoy working with the people on your team and at your company? Are you in line with the values at the company?
After you go through this exercise of self-reflection, it can be helpful to check in with an advisor or someone that knows you well like a friend or family member. They can offer different perspectives or help remove a blind spot for you.
I have had a few notable experiences where someone has shared feedback that suggested I was not in the right job and should consider other options. It caused an overwhelming sense of loss at first because I was quite comfortable in my role (or at least I thought I was). However, it was several days before I realized it was the best feedback that I had ever gotten because it led me to the next opportunity that was even better than the current one. It turned out that when I was doing my self-reflection and answering the questions above, I was not being honest with myself. Had I only relied on my own thinking, I would have not obtained the opportunities that came next.
1.What question CAN’T help you assess whether you are enjoying the work itself and accomplishing something?
A.Are you passionate about the work?
B.Do you feel you can make an impact?
C.Are you in line with the values at the company?
D.How motivated are you to do the work every day?
2.It can be helpful to tell an advisor or people acquainted with you after you finish 8 important questions of self-reflection because _________.
A.they get to the point of the matter
B.they are resourceful with numerous experiences
C.they can encourage you to figure out the number of sunny days and rainy days
D.they can view things from different angles and remind you of things likely to be neglected
3.What can we infer from the last paragraph?
A.It’s wise to answer questions right away.
B.Prior to the shared feedback, the author received the best suggestion.
C.The author was satisfied initially when others suggested considering other choices.
D.Having considered others’ shared feedback, the author had a better opportunity.
4.Which of the following best describes the author?
A.Open-minded. B.Stubborn.
C.Loyal. D.Knowledgeable.

There are a number of special days of the year that are celebrated in different countries. One of the most popular of these, even though it is fairly recent, is Mother’s Day. Mothers have always been highly regarded in all cultures. The Ancient Romans had a festival known as Hilaria, during which children took presents to the temple of the “Mother of the Gods”. The Christian Church adopted this idea and called it Mothering Sunday. However, over the years the custom was gradually forgotten and almost disappeared by the end of the 19th century.
Born in 1864 in Virginia, USA, Anna Jarvis was a school teacher and believed children should show gratitude to their mothers for all their love and care. Encouraged by a friend, she wrote to thousands of important people --- politicians, churchmen, doctors, city officials---and asked them to support her ideas: a special day of the year for thanking mothers.
In 1910 the Governor of West Virginia introduced Mother’s Day into the state. The date chosen was May 10---the second Sunday in May, which is still observed in America today. This date was chosen because May 10 was the date on which in 1908 Anna Jarvis’s mother died. In 1914 President Woodrow Wilson made May 10 the official date for Mother’s Day throughout the United States.
Soon there was a Mother’s Day International Association and the custom began to be adopted in many countries of the world.
Anna Jarvis, a sad and disillusioned (大失所望的) woman died in 1948. The custom she had worked so hard to establish and which had become almost universal had lost its original purpose. It had been taken over by business. As with Christmas, the giving of presents and the sending of cards had become a multi-million-dollar industry.

There is good reason to believe that emerging digital technologies can improve the functioning of agriculture markets at a very low cost per farmer.
Mobile phones, particularly GPS-enabled smartphones, make the provision of tailored information much easier than before. Recommendations for agrochemical inputs that address specific soil conditions can improve yields while reducing environmentally harmful and wasteful use. Farmers can tailor their investment decisions to expected weather patterns and benefit from improvements in weather forecasting. As smartphone use continues to expand, farmers will increasingly have the means to watch videos demonstrating new agricultural techniques or take pictures of pests affecting their crops and either request automatic identification and recommendations or raise questions with agronomists. Finally, digital agricultural services can improve the functioning of agricultural supply chains. For example, these services could make it easier for farmers to check and compare input or output prices ; and facilitate coordination among farmers in an area and with traders.
However, despite the potential of digital agriculture, reasons for skepticism remain. Overcoming informational restrictions may not result in substantially increased agricultural productivity, given the existence of other barriers such as input shortages at local markets, and missing insurance markets. Informational barriers are also important, and mobile phone messages may not overcome them: some farmers ignore messages, especially from unknown sources. Some farmers are illiterate and have difficulty using voice menus. Senders may design obscure and confusing messages or may provide messages designed to target objectives at odds with farmer interests. Effective communication may require pictures or video. Smartphones are thus required to receive these messages, but few farmers currently have access to this technology in the poorest countries. Finally, farmers may begin to ignore reminders they are repeated too often, or they may be annoyed by unwanted messages, which could lead to reduced trust in the messaging system.
1.According to Para 2, what can farmers do in digital agriculture?
A.They can use agrochemical to handle environmental problems.
B.They can adjust investment decisions based on weather forecasts.
C.They can identify pests on their crops by watching videos.
D.They can compete with others in prices in an efficient way.
2.What does the underlined phrase“at odds with”in the last paragraph mean?
A.In disagreement with. B.By means of.
C.In line with. D.Apart from.
3.Which of the following is NOT considered as an informational barrier?
A.Shortages of input in local markets and lack of insurance markets.
B.No access to digital technology in poorest countries.
C.Failure to read or use the voice menu on mobile phones.
D.Loss of interest and ignorance of the intended messages.
4.What is the author’s attitude towards digital agriculture?
A.Supportive. B.Doubtful. C.Objective. D.Negative.
