Human being didn't used locals for a very long time.In some parts of the world you can still find tools that people used more than two million years ago.They made these tools by hitting one stone against another.In this way，they broke off pieces from one of the stones.These chips of stone were usually sharp on one side.People used them for cutting meat and skin from dead animals，and also for making other tools out of wood.Human beings needed to use tools because they did not have sharp teeth like other meat-eating animals much as lions and tigers.Tools.jye.ai people to get food more easily.
Working with tools also helped to develop human intelligence.The human brain grew bigger，and human beings began to invent more and more tools and machines.The stone chip was one of the first tools that people used，and perhaps it is the most important.Some scientists say that it was the key to success of mankind.
Since 1960，a new kind of tool has appeared.This is the silicon chip（硅芯片）.It is smaller than a finger nail，but it can store lots of information，It is an electronic brain.Every year these chips get clever，but their size gets smaller，and their cost gets less.They are used in watches，calculators and intelligent machines that we can use in many ways.In the future we will not need to work with tools in the old way.Machines will do everything for us.People will have plenty of spare time.But what will they do with it？
Human beings used stone chips for more than two million years，but human life changed very little in that time.But now life is changing faster every day.What will life be like twenty years from now？What will the world be like two million years from now？

2．Each year on Halloween，children look forward to trick-or-treating （不請客就搗亂） for candies．But for some kids，eating Halloween candies can be dangerous．
That's because one out of every 13 kids in the Us have a food allergy（過敏癥）．They are allergic to ingredients（成分）in many Halloween candies，such as peanuts，tree nuts，milk，eggs，and beans．If they eat these foods，they will get sick or even die．
"I had to throw away all my candies with tears，" eight-year-old Conlen said．Conlen is allergic to peanuts，tree nuts，and dairy．Twelve-year-old Kylie is allergic to peanuts and tree nuts．She has been trick-or-treating only twice． "I brought my candies home and gave them to the neighbors，" Kylie said． "It felt terrible．"
But this year，Conlen，Kylie and other kids with food allergies will have a chance for a happy Halloween．That's because nearly 100，000 households across the US have promised to take part in the Teal Pumpkin Project（TPP），which was started last year by Food Allergy Research & Education（FARE）．FARE is an organization that works to improve the lives of people with food allergies．Through the project，the households agree to have nonfood items for trick-or-treaters，including trinkets（小飾品） and toys．
To take part in the project，people buy a teal（藍綠色） pumpkin or paint a pumpkin teal and place it in front of their house．The painted pumpkins let trick-or-treaters know that nonfood items are available there．The households also add their home addresses to an online map，making it easier for trick-or-treaters to find them．
Kylie loves the idea．"The TPP makes Halloween fun and safe，" she said．"It makes me feel like a normal kid，and it makes everyone feel included．"
（1）To Conlen and Kylie，the past Halloween were．

3．Besides the excitement of travel，one reason to study abroad is that you will experience new customs，holidays，foods，art，music，and politics first-hand.
"I learned the language and am now fluent，but perhaps what's more important is how much I learned about cultures，people，and myself.I learned this from the viewpoint of an active member of the community and my host family，not from the tourist's point of view，" says Andrew，who studied in Poitiers，F(xiàn)rance.
Another reason for studying abroad is that you'll gain self-confidence.Christina studied in Caracas，Venezuela，a city of more than 3 million people and a huge change from her hometown of 35，000!Christina says she learned how to better stand up for herself and her beliefs and to express herself in another language.What could make you more confident than that？
Living away from home can also help you adjust in the transition（過渡）to college and adulthood.Mathew says he returned from studying in Australia with confidence and a real interest in international affairs that made him different from his peers（同齡人）. "After having gone abroad in high school，I found the transition to college a breeze—moving 560 miles from home didn't seem particularly frightening after having lived thousands of miles away."
Most of all，it's fun while you're studying in a different learning environment.
