1 . I don't remember exactly what grade I was in when it happened. All I remember is that suddenly Math was no longer fun. Since the first grade I had always loved Math. I was good at adding and got 100 percent on almost every paper I did. All at once, though, we were doing something called multiplication（乘法）and I was not good at it. I had great difficulty in Math until the teacher gave us a card. On it were written the multiplication tables. I stared at them and smiled. Here were all the answers I needed. I read them over and over until they became stuck in my head. On our next test I did great again. I continued to love Math.
I began to notice how multiplication worked magic. I saw how a little handful of seeds could produce a garden full of food, how having two rabbits could soon give you twenty, how a few caring words could heal（治愈）a hurting heart. And I saw how a single act of loving-kindness could travel from person to person, heart to heart, and soul to soul until it circled the world.
The truth is that we are all multipliers in this life. The only question is what we are going to multiply. Are we going to multiply the feai; anger, and distrust that exist in this world? Or are we going to multiply the love, kindness, and forgiveness? I choose the latter and I hope you will do the same. Be a multiplier then. Help make this world a better place. Spend your days sowing smiles, planting kindness and sharing love. You will be amazed at how much and how rapidly it multiplies. You will be amazed at the harvest you will get in.

2 . It is like a scene from a horror film：a spider web is several meters wide，which is home to thousands of spiders.And that was what Jason G．Goldman，an animal behavior researcher，found along a muddy path in the Peruvian Amazon jungle—the web arched from tree to tree，a structure containing too many spiders to count.They appeared to function as a society，just like ants or bees.
Anelosimus eximius，the species Goldman met in the rainforest，is not the only kind of social spiders in the world，but it does construct the biggest webs.Some can reach more than 7.6m long and 1.5m wide.A web of that size could contain as many as 50,000 individual spiders.
Anelosimus eximius was first discovered more than a century ago by a French scientist named Eugene Simon.More social spiders have been discovered since.One was found as recently as 2006.
An Anelosimus eximius colony(群体) contains adult males and females as well as youngsters，but the majority of spiders on the web are females. Males account for only between 5% and 22% of any colony’s population.Social spiders work together to build，maintain and clean their webs.They work together to catch prey(猎物)，and dine together when they trap a large feast.The females work together to care for the young in the colony.They feed their youngsters by vomiting(吐出) up food for them，just like mother birds.
Why did these spiders become social？Researchers have discovered three ecological(生态的) elements that often lead to cooperative(合作的) living among spiders.
Social spiders tend to feed on bigger prey，for one thing.Spiders living in places where it is difficult to hunt large or more profitable prey alone may eventually figure out that it is in their interest to work together.
