We often talk about ourselves as if we have permanent genetic defects(缺陷) that can never be changed. “I’m impatient.” “I’m always behind.” “I always put things 1 !” You’ve surely heard them. Maybe you’ve used them to describe ___2 .
These comments may come from stories about us that have been 3 for many years—often from 4 childhood. These stories may have no 5 in fact. But they can set low expectations for us. As a child, my mother said to me, “Marshall, you have no mechanical (操作机械的) skills, and you will never have any mechanical skills for the rest of your life.” How did these expectations 6 my development? I was never 7 to work on cars or be around 8 . When I was 18, I took the US Army’s Mechanical Aptitude Test. My scores were in the bottom for the entire nation!
Six years later, 9 , I was at California University, working on my doctors degree. One of my professors, Dr. Bob Tannbaum, asked me to write down things I did well and things I couldn’t do. On the positive side, I 10 down, “research, writing, analysis, and speaking.” On the 11 side, I wrote, “I have no mechanical skills.”
Bob asked me how I knew I had no mechanical skills. I explained my life 12 and told him about my 13 performance on the Army test. Bob then asked, “ 14 is it that you can solve 15 mathematical problems, but you can’t solve simple mechanical problems?”
Suddenly I realized that I didn’t 16 from some sort of genetic defect. I was just living out expectations that I had chosen to 17 . At that point, it wasn’t just my family and friends who had been 18 my belief that I was mechanically hopeless. And it wasn’t just the Army test, either. I was the one who kept telling myself, “You can’t do this!” I realized that as long as I kept saying that, it was going to remain true. 19 , if we don’t treat ourselves as if we have incurable genetic defects, we can do well in almost 20 we choose.

查看习题详情和答案>>Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use．This is especially true in agriculture, where sustainable development is often taken as the sole measure of progress without a proper appreciation of historical and cultural perspectives．
To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so ．Medieval agriculture in northern Europe fed, clothed and sheltered a predominantly rural society with a much lower population density than it is today．It had minimal effect on biodiversity, and any pollution it brought about was typically localized．In terms of energy use and the nutrients captured in the product it was relatively inefficient．
Contrast this with farming since the start of the industrial revolution．Competition from overseas led farmers to specialize and increase yields．Throughout this period food became cheaper, safe and more reliable．However, these changes have also led to habitat loss and to diminishing biodiversity．
What’s more, demand for animal products in developing countries is growing so fast that meeting it will require an extra 300 million tons of grain a year by 2050，yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions．
All this means that agriculture in the 21st century will have to be very different from how it was in the 20th．This will require radical（激进的）thinking．For example, we need to move away from the idea that traditional practices are inevitably more sustainable than new ones．We also need to abandon the notion that agriculture can be “zero impact”．The key will be to abandon the rather simple and static measures of sustainability, which centre on the need to maintain production without increasing damage．Instead we need a more dynamic interpretation, one that looks at the pros and cons of all the various way land is used．There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity．It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting, but we do not know whether lower carbon footprints will always be better for biodiversity．
What is crucial is recognizing that sustainable agriculture is not just about sustainable food production．
72．How do people often measure progress in agriculture?
A．By its productivity B． By its impact on the environment
C．By its sustainability D．By its contribution to economic growth
73．What does the author think of traditional farming practices?
A．They have remained the same over the centuries
B．They have not kept pace with population growth
C．They are not necessarily sustainable
D．They are environmentally friendly
74．What will agriculture be like in the 21st century?
A．It will go through radical changes
B．It will supply more animal products
C．It will abandon traditional farming practices
D．It will cause zero damage to the environment
75．What is the author’s purpose in writing this passage?
A．To remind people of the need of sustainable development
B．To suggest ways of ensuring sustainable food production
C．To advance new criteria for measuring farming progress
D．To urge people to rethink what sustainable agriculture is．

Tim Berners-Lee is the man who wrote the software program that led to the foundation of the World Wide Web. Britain played an important part in developing the first generation of computers. The parents of Tim Berners-Lee both worked on one of the earliest commercial(商业)computers and talked about their work at home. As a child he would build models of computers from packaging material. After graduating from Oxford University he went on to the real thing. In the 1980's scientists were already communicating using a primitive version of e-mail. While working at a lab in Switzerland Tim Berners-Lee wrote a program, which let him store these messages. This gave him another idea that he was going to write a program that would let academics(学术界人士)from across the world share information on a single site. In 1990 he wrote the HTTP and HTML programs, which formed the basis of the World Wide Web.
The next year his programs were placed on to the Internet. Everyone was welcome to use them and improve them if they could. Programs used his codas to work with different operating systems. New things like web browsers and search engines were developed. Between 1991 and 1994 the number of web pages rose from 10 to 100,000.
In 1994 Tim Berners-Lee formed the newly World Wide Web consortium(协会), or W3C. More than 200 leading companies and labs are represented by W3C. Together they make sure that everyone can participate equally on the Web.“The Web can help people to understand the way that others live and work. It helps us understand the humanity of people”he says.
(1)From the passage we can infer that Tim Berners-Lee is most probably ________.
[ ]
A．British B．American
C．Swiss D．French
(2)The main idea of the passage is ________.
[ ]
A．when the internet came into being
B．how Tim Burners-Lee formed W3C
C．why computers develop so rapidly
D．how the World Wide Web started
(3)Scientists began to communicate using e-mail ________.
[ ]
A．in 1980 B．after the 1980's
C．before 1990 D．in the 1960's
(4)He made up his mind to write a program that would let people from across the world share information on a single site when ________.
[ ]
A．he was a child
B．he studied on Oxford University
C．he formed W3C
D．he worked at a lab in Switzerland
