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。
【微技能】概括段落大意的方法
文章通常由多个段落组成，一般来说全文只有一个主题，但每段又有不同的侧重点，因此每段又有其段落的主旨。概括段落大意常遵循以下方法：
（1）寻找主题句，确定文章主题。主题句通常在文章的开头、中间或结尾，有时主题句在开头和结尾同时出现，首尾呼应。段落大意通常是以文章的中心思想为基础，需先找出文章主旨，段落大意通常与文章主旨相关。
（2）抓住该段落的关键词语。结合文章大意再根据段落中的关键词以及细节描述来分析，概括出段落的主题。
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。
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 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，说明植物发光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）开发出一种新型产品，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。
