Lots of students do experiments on plants for their science projects. Scientists do this as well. Have you ever heard of a lie detector? It is something that police can use to figure out if you are lying or not. The machine can feel the energy in your body. If your energy moves fast,it shows you are nervous and may be lying. If it is slow and steady,it shows you are relaxed and probably honest.
Scientists attached these same machines to plants,not to see if they are lying of course,but to see what makes them nervous,what makes them calm,and what makes them excited. They found many interesting things. First,they discovered when live fish were being cut up or live lobsters(龙虾) were being boiled,the plants got very upset. They seemed to respond to the fear of the living seacreatures.
Besides,scientists found the plants actually got excited when their owners were coming home. What was even more interesting was that the plants got very excited 'when the owners stepped into the room. It seemed that the plants were so connected with their owners that they could pick up their owners’ intention to come home.
Plants also seemed not to like to be cut. When the owners pulled out a pair of scissors to cut them,they got upset. Scientists tried to frighten the plants and pretended they were going to cut them,but the plants did not get nervous in that case at all. It was as if they could read the owners’ mind. So,when taking care of your plants,remember that they are sensitive and smart.

A篇
科学家通过将测谎仪用于植物的实验告诉我们:植物不仅敏感、聪明,而且似乎能读懂人的心理。
1. D.段落大意题。本段主要介绍了什么是测谎仪以及它的工作原理。
2. C.细节理解题。根据第二段中的buttoseewhat makes them nervous,what makes them calm,and what makes them excited可知,科学家将测谎仪用于植物是为了了解什么会引起植物的各种情绪反应。
3. D.推理判断题。根据倒数第二段中的1tseemed that the plants were so connected with their owners that they could pick up their owners’ intention 和末 段中的 It was as if they could read the owners’
mind. So,when taking care of your plants,remember that they are sensitive and smart 可知,该实验发现,植物敏感而聪明,似乎能读懂人的心 思。
4. B.细节理解题。根据末段中的Scientists tried to trick the plants and pretended they were going to cut them可知,科学家使用剪刀是假装要修剪植物,以便观察它们的反应。
