题目与答案

1. An example of how farmers in one country are now using satellite data to determine fertiliser use.
   • A
   • B
   • C
   • D
   • E
   • F

   答案：C

   原文定位：Five years ago, for example, a French cereal-growers' co-operative called Sevepi purchased a satellite and makes it available to its members in the form of maps of their fields, divided into three or four colour-coded zones per hectare. For each zone, the exact and best fertiliser formula is recommended

2. 15 A reference to climate change and its effects.
   • A
   • B
   • C
   • D
   • E
   • F

   答案：D

   原文定位：Moreover, Henri Douche, head of Infoterra's agriculture sales in Toulouse, reckons the amount of monitored farmland will increase as weather patterns change and farmers can no longer rely on the past as a guide to the future. When confounded by the yield variations that these new weather patterns will bring, even farmers who are afraid of new technology will sign up, he says

3. 16 A reference to the effect on the soil of using too much fertiliser.
   • A
   • B
   • C
   • D
   • E
   • F

   答案：E

   原文定位：the satellite data it purchases is proving useful for the study of fields with declining productivity in the province of Saskatchewan. Over-application of nitrate fertilisers (which are also a source of greenhouse gases) appears partly responsible

4. 17 An example of information that will be shared between different countries.
   • A
   • B
   • C
   • D
   • E
   • F

   答案：G

   原文定位：Once passed on to the International Centre for Tropical Agriculture, based in Colombia, South America, it is intended that the information be used to build a database called the 'Digital Soil Map'. When complete, this will provide farmers with free forecasts, developed with regularly updated satellite imagery, across farmland in the poorest countries in Africa

5. 18 Mention of the country which is the leader in agricultural technology.
   • A
   • B
   • C
   • D
   • E
   • F

   答案：D

   原文定位：France is the pioneer in this sort of surveillance. More farmland is analysed by satellite there than in any other country, according to Infoterra (a subsidiary of EADS Astrium), the firm that is France’s largest provider of such information

6. 19 A description of an innovation in satellite imaging which requires further study.
   • A
   • B
   • C
   • D
   • E
   • F

   答案：F

   原文定位：Our satellites are the first commercial satellites to include the Red-Edge band of the light spectrum, which is sensitive to changes in chlorophyll content. More research will be necessary to realise the full benefits of the Red-Edge band

7. 20 Evidence of the cost-effectiveness of using satellite technology in agriculture.
   • A
   • B
   • C
   • D
   • E
   • F

   答案：B

   原文定位：The service usually costs less than US $15 per hectare for a handful of readings a year, and can increase yields by as much as 10%

8. 21-22 Which TWO companies obtain information directly from satellites?
   • A Sevepi
   • B Infoterra
   • C Agriculture and AgriFood Canada
   • D RapidEye
   • E World Agroforestry Centre

   答案：B Infoterra,D RapidEye

   原文定位：Infoterra (a subsidiary of EADS Astrium), the firm that is France’s largest provider of such information, supplying data to companies such as Sevepi

9. 23 Initially, orbiting satellites are used to measure _____ coming from farmland.

   答案：electromagnetic radiation

   原文定位：Precise prescriptions for growing crops can be obtained quickly, and less expensively, by calculating the amount of electromagnetic radiation reflected from agricultural land. The data is collected by orbiting satellites

10. 24 Fredrick Jung-Rothenhäuser says that additional irregular weather will raise the _____ of satellite technology.

    答案：importance

    原文定位：reckons the amount of monitored farmland will increase as weather patterns change and farmers can no longer rely on the past as a guide to the future. When confounded by the yield variations that these new weather patterns will bring, even farmers who are afraid of new technology will sign up

11. 25 As a result of satellite technology, it may become possible to insure against the threat of _____ in some countries.

    答案：crop failure

    原文定位：And according to RapidEye, a German satellite operator, some companies are also studying satellite data with a view to selling insurance policies to governments of famine-prone countries that might be threatened by crop failure

12. 26 In Africa, much of the soil suffers from the loss of _____ .

    答案：nutrients

    原文定位：In Africa, where many areas have become badly depleted of nutrients, better fertiliser management would help reverse this situation
