Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago.
Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Company. The idea for the product came from an awful experience he often had while singing in his church choir. Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. Around that time, Fry heard about a new adhesive (粘合剂) that a colleague, Dr. Spence Silver, had created. This adhesive was special because it was strong enough to hold papers together, but not strong enough to tear the paper when it was removed.
A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new “bookmarks” and attached it to a report he was going to give to a colleague. Soon, co-workers were asking Fry for more of his invention so that they could use the new type of notes themselves.
Fry and some other people at 3M believed so much in the new product that they asked the company to give away thousands of the “sticky pieces of paper” for trial use. When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.How did Dr. Spence help Art Fry?

President Obama: I want to welcome Vice President Xi to the Oval Office and welcome him to the United States. This is obviously a great opportunity for us to build on the U. S,-China relationship, but also an opportunity to return the extraordinary hospitality (款待) that Vice President Xi showed Vice President Biden during his recent visit to China.
As I indicated during my recent visit to APEC and the East Asia Summit, the United States is a Pacific nation. And we are very interested and very concentrated on continuing to strengthen our relationships, to enhance our trade and our commerce, and make sure that we are a strong and effective partner with the Asia Pacific region. And obviously, in order to do that, it is absolutely vital that we have a strong relationship with China.
So, Mr. Vice President, I hope you have a wonderful visit while you're here. I'm sure the American people welcome you. I'm glad that you're going to get an opportunity to get out of Washington. I know you'll be visiting Iowa, which you visited many years ago when you were governor. And I understand you're also going to Los Angeles and maybe even taking in (观看) a Lakers basketball game. So I hope you enjoy that very much.
I want to extend my deepest welcome to you, and look forward to a future of improved dialogue and increased cooperation in the years to come.Where can you most probably read the passage?

Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry’s manufacturer, recommends 2.5 centimeters.
If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion(万亿)minutes annually - earn $109 billion for the wireless carriers.
Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid（易吸收的液体）. No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen（腹部）.Why is the warning in the small print?
| A．They think people will not care about it. |
| B．There is not enough space for the warning. |
| C．They don’t want the users to pay attention to it. |
| D．The warning is not important at all. |
What does the underlined word in sixth paragraph probably mean?
| A．acceptable | B．valuable | C．accessible | D．easily affected |
What can we conclude from the last paragraph?
| A．Pregnant women should keep cell phones away. |
| B．People should use cell phones in the correct way. |
| C．If you are a child, you’d better text than make phone calls. |
| D．When you use a cell phone, use a wired headset or the phone’s speaker. |
What does the passage mainly talk about?
| A．Be careful when using cell phones. |
| B．Don’t hold your cell phone against your ear. |
| C．Rats exposed to radiation have damaged DNA in their brains. |
| D．Low-energy radiation could damage cells that could lead to cancer. |

When I was growing up, 16 was always a magical age, a symbol of maturity, responsibility and of course more independence and freedom. I sat through the hours of Driver’s Ed classes eager to get out on the road. I couldn’t wait to get my driver’s license.
But it’s a different story for today’s teens. In January, the U.S. Department Transportation released 2012 data that showed only 30.7 percent of U.S. teens got their license at age 16, Twenty years before, that number was almost 45 percent.
There are numbers of reasons for the fall – off. The growing responsibilities like paying for insurance and high gas prices discourage teens from getting behind the wheel. Plus, many teens today are so busy with homework, endless hours of activities and part-time jobs, that finding the time for Driver’s Ed classes may be more difficult that ever.
In addition, many states have raised the driving age, or restricted when teens can drive and who they can have in the car. Parents may also be making their own personal restrictions until they feel their teens are responsible enough to drive safely.
Driving is part of the American culture, but it’s not the central focus like it was 25 years ago. They have so many other things to do now. One of the more interesting factors delaying teens driving might be the change of their social life. Today, teens need to look no further than Face book or other social networking sites to connect with their friends. There is simply less need, maybe less desire, to be able to grab the keys and go.
Michelle Wei got her license as a senior in high school because her digital social life made it easy no to drive. “If I couldn’t get a ride to see my friend who lives a town over,” the 19-year-old said, “I could talk on IM or Skype.”
Research has shown that these online relationships can lead to higher quality friendships, so it isn’t necessarily a bad thing. However, it’s important to find a balance. If old face-to-face friendships are good, why not drive to find them?We can infer from the first paragraph that .
| A．Driver’s Ed classes allowed teens to know what maturity was |
| B．getting a driving license at 16 was a must for American teens |
| C．16 was considered an age when one could get his driver’s license |
| D．teens could drive on the road without taking Driver’s Ed classes |
What does the passage mainly talk about?
| A．Desire to drive on the road declines among American teens. |
| B．Getting a license costs much more than ever before. |
| C．Social networking sites are changing the life of American teens. |
| D．American teens are becoming more responsible than ever. |
Michelle’s Wei’s example is used to explain ________.
| A．why American teens are crazy about digital social life |
| B．what social networking websites are bringing to American teens |
| C．to what degree the Internet is affecting the American car culture |
| D．what the Internet does to help teens to get a driving license |
The last paragraph is reminding the readers that.
| A．the Internet h as a bad effect on the teen’s social life |
| B．teens should keep a balance in choosing their lifestyle |
| C．actual contacts can be replaced by talking on line |
| D．face-to-face friendship is always the best choice |
