I spotted (發(fā)現(xiàn);認出) him at the checkout counter, bagging at No.14. His arms shook violently as he placed a carton (紙板箱;紙盒) of eggs into a plastic bag. He wore a yellow plastic name tag on which he had written “Jerry” in kindergarten penmanship (書法). He looked middle-aged but his mental age must have been about 12.
Ever since I smiled at him the first time he bagged my groceries at my local supermarket, Jerry has followed me around like an adoring fan. His lack of boundaries makes me uncomfortable. I don’t know how to avoid being noticed by him. I don’t want to speak to the manager — my complaint could get him fired. So I start avoiding him.
There are other grocery stores, but I choose this one because it employs people with disabilities, from which my brothers have also suffered.
Last Wednesday after I finished choosing what I wanted, I turned around and drove my cart to Checkout No.3, hoping Jerry would not notice me and stay at No.14.
“Paper or plastic, ma’am?” Jerry’s soft voice surprised me from behind. “Paper, please.” I noticed that the checkout stand created plenty of space between Jerry and the clerk. In this situation, he knew where to stand. The clerk said to me: “＄27.30, please.” I handed my own cart, signed my receipt and stepped around the counter, where Jerry was holding my last packet of biscuits. He came towards me, stopping an inch from me. He was too close. I wanted to dash out of the store and leave behind the packet. Instead, I stood with my hand frozen on the cart. His eyes looked lonely — I knew they would follow me after I left the store. I wanted to apologize for my coldness. “I’m …I’m sorry.” A tiny voice inside me said. I tapped my head with my hand as if I had forgotten something. “Forgive me. I’m from New York City. I’m not used to people being so helpful.”
He laughed. I laughed. His eyes brightened. “It’s my job, ma’am. I like it.” he said. When he offered to push my cart, I didn’t care but nodded deeply.

I believe that animals possess greater intelligence than most people think. But plants? I've never considered the possibility of plant intelligence. The idea seems absurd.
Yet I've had friends argue that plant intelligence might exist. "What are the differences between plants and animals?" they ask, and then they argue about certain species that seem to share the intelligence of both plants and animals.
New research suggests that plants communicate via "networks". Plant communication is not idea, and cannot indicate that its is a kind of intelligence, but it is still interesting.
Recent research from Vidi researcher Josef Stuefer at the Radboud University Nijmegen shows that plants have their own chat systems that they can use to warn each other. Therefore plants are not boring and passive organisms that just stand there waiting to be cut down or eaten up. Many plants form internal communication networks and are able to exchange information networks and are able to exchange information efficiently.
Many herbal plants such as strawberries and clovers (三葉草)naturally form networks.
Individual plants remain connected with each other for a certain period of time by means of runners (plant stems that grow along the ground and put down roots to form new plants). These connections enable the plants to share information with each other via internal channels. They are therefore very similar to computer networks. But what do plants chat to each other about?
Recently Stuefer and his colleagues were the first to prove that clover plants warn each other via the network links if danger is nearby . If one of the plants is attacked by caterpillars (毛蟲)，the other members of the network are warned via an internal signal. Once warned the intact (完好無損的)plants strengthen their chemical and mechanical (機體的)resistance so that they are less attractive to advancing caterpillars. Thanks to this early warning system, the plants can stay one step ahead of their attackers. The research has shown that this significantly limits the damage to the plants.
Again, I don't believe this reflects intelligence, but it's is certainly fascinating.
