3．Like millions of other houses on this planet，my house is made out of wood，glass and stone．However，it is also made out of software．
If you come to visit，you'll probably be surprised the minute you come in，when you will be presented with an electronic PIN （個人身份號碼）to wear，which tells the house who
and where you are．The house uses this information to give you whatever you need．When it's dark outside，the PIN turns on the lights nearest you，and then turns them off as you walk
away from them．Music moves with you too．If the house knows your favorite music，it plays it．The music seems to be everywhere，but in fact other people in the house hear different music or no music．If you get a telephone call，only the nearest telephone rings．
Of course，you are also able to tell the house if you want something．There is a home control console （控制臺），a small machine that turns things on and off around you．
The PIN and the console are new ideas，but they are in fact like many things we have today．If you want to go to a movie，you need a ticket．If I give you my car keys，you can use my car．The car works for you because you have the keys．My house works for you because you wear the PIN or hold the console．
I believe that ten years from now，most new homes will have the systems that I've put in my house．The systems will probably be even bigger and better than the ones I've put in today．
I like to try new ideas．I know that some of my ideas will work better than others．Today's leading-edge technology will help me build tomorrow's better home．But I hope that one day I will stop thinking of these systems as new，and ask myself instead，"How will I live without them？"

61According to the passage，the author is probably a（n）D．
A．musician
B．architect
C．experienced teacher
D．IT expert
62．What does the passage mainly discuss？A
A．A home for the future．B．The function （功能） of the PIN．
C．How to develop a new system．D．Easy life in the future．
63．What's the purpose when the writer wrote the fourth paragraph？B
A．To let readers know why his ideas are new．
B．To explain more easily what the functions of the PIN and the console are．
C．To explain the importance of the PIN and the console．
D．To let readers know how special his house is．
64．The writer's new house is different from ordinary ones mainly because D．
A．it has your favorite music following you
B．you can make a telephone call anywhere
C．the writer is able to change his new idea into practice
D．it has been controlled by computers．
65．What does the last sentence mean？B
A．The writer won't invent new things．
B．The writer hopes the systems will become part of everyday life in the future．
C．The writer can't live without his systems in his house．
D．The writer hopes that he will be able to come up with more new ideas in the future．

8．October 15^th is the Global Hand washing Day．Activities are planned in more than 20countries to get millions of people in the developing world to wash their hands with soap．For example，donors（捐贈者） will give 150，000bars of soap to schools in Ethiopia．
Experts say people around the world wash their hands every day，but very few use soap at so-called important moments．These include after using the toilet，after cleaning a baby and before touching food．
Global Hand washing Day is the idea of the Public-Private Partnership for Hand washing with Sap．Partners include the United Nations Children's Fund，American government agencies，the World Bank and soap makers Unlever and Procter and Gamble．The organizers say all soaps are equally effective at removing disease-causing germ（細菌）．They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap．Rub（揉搓） it into all areas，including under the fingernails（指甲）．Rub for at least twenty seconds．Then rinse well under running water．Finally，dry your hands with a clean cloth or wave them in the air．
The Partnership for Hand washing says soap is important because it increases the time that people spend in wshing hands．Soap also helps to break up the dirt that holds most of the germs．And it usually leaves a pleasant smell．The Partnership for Hand washing also says washing with soap before eating or after using the toilet could save more lives than any vaccine（疫苗）or medicine．Hand washing could also prevent the spread of other diseases．When people get germs on their hands，they can infect（感染）themselves by touching their eyes，noses or mouths．Then they can infect others．

51．What's the best title for this passage？C
A．Say no to washing hands in the wrong way．
B．Find out why washing hands carefully is so important．
C．Hand washing：so important----it gets a day of its own．

A．to dry your hands
B．to wash away the soap
C．to rub your hands carefully
D．to clean your fingers
53．The last paragraph mainly tells usB．
A．how to wash your hands correctly
B．why washing hand with soap is so important
C．the dangers of washing hands without soap
