Weve been able to make up the difference in income by 25 without appreciably lowering our standard of living. We continue to dine out once or twi

We eat less meat, drink cheaper wine and see fewer movies. 27 Christmases are a memory, and we combine vacations with story assignme

17、nts I suspect not everyone who loves the country would be happy living the way we do. It takes a couple of special qualities. One is a 28 for solitude. Because we are so busy and on such a tight budget, we dont entertain much. During the growing season there is no time for socializing anyway. Jim an

18、d Emily are 29 in school activities, but they too spend most of their time at home. The other requirement is energy a lot of it. The way to make self-sufficiency work on a small scale is to resist the 30 to buy a tractor and other expensive laborsaving devices. Instead, you do the work yourself. The

19、 only machinery we own (not counting the lawn mower) is a little three-horsepower rotary cultivator and a 16-inch chain saw. A) picks up B) temptation C) given D) generate E) involved F) instead of G) Extravagant H) cutting up I) cutting back J) endurance K) covered L) Aside from M) tolerance N) exo

For each of them there are four choices marked A), B), C) and D). You should decide on the best choice. Passage One Questions 31 to 35 are based on the fo

21、llowing passage. Genetically modified foods (or GM foods) are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. GM foods were first put on the market in the early 1990s. Typically,

22、genetically modified foods are transgenic plant products: soybean, corn, canola, and cotton seed oil. Animal products have also been developed, although as of July 2010 none are currently on the market. Critics have objected to GM foods on several grounds, including safety issues, ecological concern

23、s, and economic concerns. However, genetically-modified foods are here to stay. Thats not to say that food produced by conventional agriculture will disappear, but simply that food-buying patterns will polarize (两极分化): there will be a right market for conventional food just as there is for organic f

24、ood. It may even be that GM food will become the food of preference because consumers come to appreciate the health benefits of reduced pesticide use. The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the worlds predicted

25、population growth to ten or eleven billion. Its not just a question of more mouths to feed either. What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture. Genetic modification is analogous to nuclear power: nobody loves it, but

26、climate change has made its adoption imperative, says economist Paul Collier of Oxford University. Declining genetic modification makes a complicated issue more complex. Genetic modification offers both faster crop adaptation and a biological, rather than chemical, approach to yield increases. The w

27、orld has 800 million hungry people. Until now, food supplies have been increased by improved varieties, pesticides and artificial fertilizers: the green revolution. Now were on the edge of a new revolution: a genetic one. It may well be that in the long term it is the developing world that benefits

28、most from GM foods. Its true that for the next ten years or so GM crops may be too expensive. But the lesson of personal computers is applicable here once the technology has been developed for profitable crops, it will spread and become affordable for all. This doesnt mean, unfortunately, that famin

29、es will disappear, but severity and duration will be helped by an improved ability to produce and distribute food. 31. The introduction of GM food will affect _. A) food-pricing standard B) food-buying patterns C) food-supplies scale D) food-production efficiency 32. Consumers prefer GM food to conv

30、entional food because _. A) GM food receives less pesticide application B) GM food is more nutritious than organic food C) GM food is cheaper than conventional food D) Conventional food is free from chemicals 33. If the world population grows to ten or eleven billion by the year 2050, _. A) a geneti

31、c revolution will take over the green revolution B) the overall land available for agriculture will run out C) the number of hungry people will rise to 800 million D) food production should be increased to three times that of today 34. But the lesson of personal computers is applicable here (in the

32、last paragraph) probably means that _. A) once the technological innovation is in progress, its cost will be reduced B) once the technology has been turned into productivity, it will become popular C) once the technology has been developed for profitable products, it will enter into our daily life D) once t
