9．Welcome to your future life!
You get up in the morning and look into the mirror．Your face is firm and young-looking．In 2035，medical technology is better than ever．Many people your age could live to be 150，so at 40，you're not old at all．And your parents just had an anti-aging （抗衰老的） treatment．Now，all three of you look the same age!
You say to your shirt，"Turn red．"It changes from blue to red．In 2035，"smart clothes"contain particles （粒子） much smaller than the cells in your body．The particles can be programmed to change clothes'color or pattern．
You walk into the kitchen．You pick up the milk，but a voice says，"You shouldn't drink that!"Your fridge has read the chip （芯片） that contains information about the milk，and it knows the milk is old．In 2035，every article of food in the grocery store has such a chip．
It's time to go to work．In 2035，cars drive themselves．Just tell your"smart car"where to go．On the way，you can call a friend using your jacket sleeve．Such"smart technology"is all around you．
So will all these things come true？"For new technology to succeed，"says scientist Andrew Zolli，"it has to be so much better that it replaces what we have already．"The Internet is one example---what will be the next？
21．What can be inferred from Paragraph 4？C
A．Milk will be harmful to health．
B．More drinks will be available for sale．
C．Food in the grocery store will carry electronic information．
D．Milk in the grocery store will stay fresh much longer．
22．Which of the following is mentioned in the text？D
A．Nothing can replace the Internet．
B．Fridges will know what people need．
C．Jacket sleeves can be used as a guide．
D．Cars will be able to drive automatically．
23．What is the text mainly about？B
A．Food and clothing in 2035．
B．Future technology in everyday life．
C．Medical treatments of the future．
D．The reason for the success of new technology．

分析 本文是一片科技小短文，主要暢想了未來30-50年人們生活所發(fā)生的一系列變化．隨著新技術(shù)的成功，人們未來的生活變得越來越美好：壽命可以延長至150歲，智能衣服的顏色也是隨心而變，食物上也裝有芯片，汽車可以自動駕駛．

解答 21．C．推理判斷題．根據(jù)文章的第四段第三句中"…the chip（芯片）that contains information…"及最后一句"…every article of food in the grocery store has such a chip．"可知，食品店里的每一份食品都帶有這樣一個芯片，芯片中都有電子信息，故選C．
22．D．推理判斷題．根據(jù)文章倒數(shù)第二段第二、三句"In 2035，cars drive themselves．Just tell your"smart car"where to go．"可知，在2035年，汽車可以自動駕駛．你只要告訴你的"聰明的汽車"去哪里就可以了．故選D．其余三項均與文章內(nèi)容不符．
23．B．主旨大意題．文章描述了2035年人們生活的幾個方面，這些均源自科技的發(fā)展，所以B項正確．A：2035年的食品與服裝；C：未來的醫(yī)療；D：新技術(shù)成功的原因．

點評 本文是一個科教類閱讀理解，題目涉及多道細節(jié)理解題，做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進行仔細分析，結(jié)合選項選出正確答案．推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案，切忌胡亂猜測，一定要做到有理有據(jù)．

Investing in yourself

Figuring out how to invest your money can be a difficult task. This is something that you will want to learn how to do.

1. Things that will improve your knowledge, skills or health are all great investments. However, before you start, you need to be clear about what you will gain out of doing all of these things.

You may think investing in yourself means investing in your education. 2.. There are some other things you can do as well as buying a gym membership or learning a new skill.

So what are some specific things you can do? 3.. Reading books can really expand your mind and allow you to learn different skills and gain knowledge. I’m talking about the books where you will actually learn a new skill, not fiction books.

You can also take courses and attend seminars. These programs are taught by people with a high level of knowledge or skill. 4.. Only in this way can you avoid being fooled by some sales presentation.

Moreover, investing in yourself is a safe way to keep your money. Although a savings account is seen as the most secure investment, that isn’t 100% safe. Even if you never experience your bank closing down, the return is little when inflation(通貨膨脹) is taken into consideration. 5.. But over time, they will show up in terms of your happiness level as well as your level of success.

A. This is just one way.

B. The benefits will stay with you.

C. If you aren’t a reader, you should start with that.

D. The more you do this, the more valuable you will be.

E. Of course, you need to do some research before investing.

F. The best way to invest your money is to invest it in yourself.

G. When you invest in yourself, you may not see gains right away.

14．People are being lured （引誘）onto Facebook with the promise of a fun，free service without realizing they're paying for it by giving up large amounts of personal information．Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages．
Most Facebook users don't realize this is happening．Even if they know what the company is up to，they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth．
The biggest problem，however，is that the company keeps changing the rules．Early on，you keep everything private．That was the great thing about facebook-you could create your own little private network．Last year，the company changed its privacy rules so that many things-your city，your photo，your friends'names-were set，by default （默認）to be shared with everyone on the Internet．
According to Facebook's vice-president Elliot Schrage，the company is simply making changes to improve its service，and if people don't share information，they have a"less satisfying experience"．
Some critics think this is more about Facebook looking to make more money．Its original business model，which involved selling ads and putting them at the side of the page，totally failed．Who wants to look at ads when they're online connecting with their friends？
The privacy issue has already landed Facebook in hot water in Washington．In April．Senator Charles Schumer called on Facebook to change its privacy policy．He also urged the Federal Trade Commission to set guidelines for social-networking sites．"I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them，"Schrage admits．
I suspect that whatever Facebook has done so far to invade our privacy，it's only the beginning，which is why I'm considering deactivating（撤銷）my account．Facebook is a handy site，but I'm upset by the idea that my information is in the hands of people I don't know．That's too high a price to pay．

66．What do we learn about Facebook from the first paragraph？C
A．It is a website that sends messages to targeted users．
B．It makes money by putting on advertisements．
C．It profits by selling its users'personal data．
D．It provides loads of information to its users．
67．What does the author say about most Facebook users？B
A．They are reluctant to give up their personal information．
B．They don't know their personal data enriches Facebook．
C．They don't identify themselves when using the website．
D．They care very little about their personal information．
68．Why does Senator Charles Schumer propose？C
A．Setting guidelines for advertising on websites．
B．Banning the sharing of users'personal information．
C．Working out regulations for social-networking sites．
D．Removing ads from all social-networking sites．
69．Why does the author plan to cancel his Facebook account？C
A．He is dissatisfied with its current service．
B．He finds many of its users untrustworthy．
C．He doesn't want his personal data to be used in a wrong way．
D．He is upset by its frequent rule changes．
