Field trail - heat pump technology

文章大意

本文介绍英国一项热泵技术实地试验。热泵从空气或地下吸取低温热量并提升温度，用于家庭中央供暖和热水，替代传统锅炉。试验监测了83个英国站点，发现性能差异很大；文中还提到储水需定期升至60摄氏度以杀灭细菌。

题目与答案

1. Background:

   ·Aim in the UK is reduce carbon emissions from energy consumed in 31_____ by approximately 25%

   答案：homes

   原文定位：Twenty-seven percent of British carbon dioxide emissions come from the energy used in homes. So around a quarter of all reductions must also come from that sector rather than industry

   同义替换：「consumed」↔「used」，「approximately」↔「around」

2. ·Most popular “green” energy: 32_____ .

   答案：solar

   原文定位：At present, the most popular green energy from a range which includes wind, biomass heating, and ground heat is solar

3. ·Little investment in heat pumps in the UK due to lack of 33_____ in using them.

   答案：experience

   原文定位：Heat pump technology is relatively new to the UK market, and because there is such limited experience of this technology, people have been reluctant to invest in it

   同义替换：「lack」↔「limited」，「little」↔「reluctant」

4. What is a heat pump?

   ·Heat pumps serve the same purpose as a 34_____.

   答案：boiler

   原文定位：The heat pumps in this trial are used for the same reason you'd use a boiler

   同义替换：「serve the same purpose as」↔「used for the same reason」

5. ·Most heat pumps get heat from the earth or the 35_____ .

   答案：air

   原文定位：Most heat pumps take heat from either the ground or the air

   同义替换：「get heat from」↔「take heat from」，「earth」↔「ground」

6. ·Water is heated to 60℃ to destory 36_____ .

   答案：bacteria

   原文定位：The general advice in the UK is that the temperature of the hot water stored in a cylinder should be periodically put up to sixty degrees centigrade to kill off bacteria

   同义替换：「destroy」↔「kill off」

7. The Field Trial:

   ·83 sites across the UK

   ·Central heating systems monitored: 37_____ and under-floor heating.

   答案：radiators

   原文定位：This field trial monitored two central heating systems;radiators and under-floor heating

8. (本题暂无）38_____

   答案：暂无答案

   原文定位：Installation need to provide improved training in pump-fitting technique

9. ·39_____ designs performed best.

   答案：simple

   原文定位：It was found that in most cases, designs which were simple were more efficient

   同义替换：「performed best」↔「simple were more efficient」

10. ·Customers needed to be told about regulating the controls.

    ·Need for a 40_____ to coordinate the installation.

    答案：supervisor
