One f his latest prjects has been t make plants glw（发光）in experiments using sme cmmn vegetables. Stran’s team fund that they culd create a faint light fr three-and-a-half hurs. The light, abut ne-thusandth f the amunt needed t read by, is just a start. The technlgy, Stran said, culd ne day be used t light the rms r even t turn trees int self-pwered street lamps.
In the future, the team hpes t develp a versin f the technlgy that can be sprayed nt plant leaves in a ne-ff treatment that wuld last the plant’s lifetime. The engineers are als trying t develp an n and ff “switch” where the glw wuld fade when expsed t daylight.
Lighting accunts fr abut 7% f the ttal electricity cnsumed in the US. Since lighting is ften far remved frm the pwer surce（电源）—such as the distance frm a pwer plant t street lamps n a remte highway—a lt f energy is lst during transmissin（传输）. Glwing plants culd reduce this distance and therefre help save energy.
1. What is the first paragraph mainly abut?
A. A new study f different plants.
B. A big fall in crime rates.
C. Emplyees frm varius wrkplaces.
D. Benefits frm green plants.
2. What is the functin f the sensrs printed n plant leaves by MIT engineers?
A. T detect plants’ lack f water.
B. T change cmpsitins f plants.
C. T make the life f plants lnger.
D. T test chemicals in plants.
3. What can we expect f the glwing plants in the future?
A. They will speed up energy prductin.
B. They may transmit electricity t the hme.
C. They might help reduce energy cnsumptin.
D. They culd take the place f pwer plants.
4. Which f the fllwing can be the best title fr the text?
A. Can we grw mre glwing plants?
B. Hw d we live with glwing plants?
C. Culd glwing plants replace lamps?
D. Hw are glwing plants made pllutin-free?
【语篇导读】科学家们致力于研究人与植物之间的关系，并使用科技手段来改造植物。本文主要介绍了针对“发光植物”的研究，包括其现有成果、对该项技术的预期和畅想及其可能产生的积极影响。
1. D主旨大意题。根据第一段中的psitive effects及所举的两个例子（绿化多的区域犯罪率低以及绿植多的办公区域员工的工作效率更高）可知，本段主要介绍
的是绿色植物给人们带来的益处。故选D项。
2. A细节理解题。根据题干中的关键信息sensrs printed n plant leaves可定位至文章第二段。根据第二段第二句中的These include plants that have sensrs printed nt their leaves t shw when they’re shrt f water可知，这些传感器是用来检测植物是否缺水的。故选A项。
【微技能】细节理解题的命题特征
细节理解题一般包括直接理解题、语义转化题、数字计算题、排列顺序题、图表图画题等。抓住文段中的事实和细节是做好该类题的关键，也是做好其他类型的题的基础。
直接理解题在原文中可直接找到答案，常用wh，what，when，where，why和hw等提问。语义转化题需要将题目信息与原文相关信息进行语义上的转换，因两者存在表达上的差异，有时需要进行加工或整理后方能得出结论。近年来细节理解题已由简单的对号入座直接答题转向通过语句的同义或反义转换来考查学生对英语语言的理解能力，因此难度比往年有所增加。
3. C细节理解题。根据最后一段最后一句Glwing plants culd reduce this distance and therefre help save energy.可知，“发光植物”可以减少由于远距离输送而产生的电力资源的浪费，从而节约能源。故选C项。
4. C主旨大意题。通读全文可知，本文第一、二段为导入部分，引出科学家正在进行与植物相关的各种实验这一话题，从第三段开始重点介绍“发光植物”的实验，结合文中的The technlgy…culd ne day be used t light the rms r even t turn trees int self-pwered street lamps.可知，未来“发光植物”有可能取代电灯，用来给房间和街道照明，后文围绕其继续展开介绍，说明发光植物可能给人们带来的益处，故C项（发光的植物有可能取代灯吗？）最适合作本文的标题。
【长难句分析】In the future, the team hpes t develp a versin f the technlgy that can be sprayed nt plant leaves in a ne-ff treatment that wuld last the plant’s lifetime.
句式分析：本句中主句的主语为 the team，谓语部分为hpes, t develp a versin f the technlgy为宾语；第一个that引导的是定语从句，修饰先行词a versin f the technlgy；第二个that也是引导定语从句，修饰先行词a versin f the technlgy that a ne-ff treatment。
句意：未来，该团队希望（在该技术的基础上）开发出种新型产品，将该产品一次性喷洒在植物的叶子上，即可延长植物的寿命。
