D. I managed somehow.
IMAGINE if there was a device that could do everything for you – wake you up every morning, chat with you and type your e-mails.
The piece of technology in question would be smart, able to tell you about the weather and where the nearest restaurants are.
The good thing is you no longer need to wonder, because something like this already exists. And its name is Siri.
Siri is a voice recognition application designed for Apple products and the concept has been around for almost a year.
When Siri first came out it could only speak English, but now it has “learned” lots of new languages, including Chinese, Cantonese and Taiwanese, reported The Wall Street Journal. So, you can give it orders in your mother tongue.
But how could a cell phone or a computer “hear” what you are saying and understand it? This is all because of voice recognition technology.
When you speak, your voice creates vibrations (振动) in the air – a bit like waves in the water when you throw a rock into the lake. The microphone receives the vibrations and the computer changes them into digital data that is then divided into many parts. They are analyzed one by one to see what pronunciations each part stands for. The computer then puts these pronunciations together into possible words according to its built-in dictionary.
But figuring out the words is far from enough; building words into meaningful sentences is the most difficult part. The computer has to compare what it hears to a large library of known phrases and sentences to determine what the user is saying.
However, people don’t always talk in the most standard way and sometimes make grammatical mistakes. This is why traditional voice recognition software always requires you to remember keywords and to speak in a certain way.
Fortunately, Siri isn’t like that. It’s not just “voice recognition”; it’s “natural language understanding (NLU)”. You can ask it things like “Do I need an umbrella today?” and it will know that you are asking about the weather, according to ABC News.
“The key thing is NLU – understanding what you mean and what you want,” Neil Grant from Nuance, a software company in the US, told The Guardian. “Historically, you had to learn a huge long list of commands . As NLU progresses, you can say what you want in a way that’s natural to you.”

Many Americans have been leaving their cars at home and riding to work on bicycles. Andy Clark is the leader of the League of American Bicyclists. His group supports bicycling for fun, fitness and transportation.
Clark says this is good news for the environment. He says riding a bicycle to work does not burn fossil fuel or creates dangerous pollutions. Experts say the effects are the most important on short trips. The Department of Transportation says fifty percent of Americans drive eight kilometers or fewer to work. Shorter car trips set out more pollution into the air for each kilometer drive. This is because the car engine will set out the harmful air when it warms up before it can work well.
James, a members of Congress (国会), is a strong supporter of bicycle use. He says cities, counties, state governments and state highway transportation agencies are planning the roadways of the future. They are creating roads and paths for bicycles in cities and between communities.
Last year, Portland, the Pacific Northwest city in the state of Oregon, had the highest percentage of bicycle users in the United States. Portland has been doing progressive city planning for many years to create special paths for bike riders.
【小题1】 What happened in America now according to the news?
| A．Many Americans lost jobs now. |
| B．Many Americans prefer short trips. |
| C．There are more and more bicyclists now in America. |
| D．The pollution is getting worse and worse in America. |
A. One of the cities in the USA. B. One of the counties in the USA.
C. One of the states in the USA. D. A country in the northwest of the USA.
【小题3】What does the underlined word “harmful” mean in the second paragraph? The closest meaning is “_______”.
| A．polluted | B．dangerous | C．clean | D．foolish |
| A．Many Americans like bike-riding for fun. |
| B．Short car trips can reduce pollution. |
| C．American government suggests people riding bicycles. |
| D．Many Americans ride bicycles to support environment protection. |
Today we tell about the expression “down to earth”．Down to earth means being open and honest．It is easy to deal with someone who is down to earth．Such people could be important members of society, but they do not consider themselves to be better than others who are less important．They do not let their importance “go to their heads.” Someone who lets something go to his head feels he is better than others．He has a “big head.”
A person who is filled with his own importance and pride is said to have “his nose in the air．”Often the person who has a big head and his nose in the air has no reason to feel better than others．
Americans use another expression that is similar in some ways to down to earth---“both feet on the ground.” Someone with both feet on the ground is a person with a good understanding of reality．She has what is called “common sense.” She does not allow her dreams to block her understanding of what is real．
The opposite kind of person is one who has his “head in the clouds.” Someone with his head in the clouds is a person whose mind is not on what is happening in real life．Such a person may be called a “daydreamen.”
The person who is down to earth usually has both feet on the ground．But the opposite is not always true．Someone with both feet on the ground may not be as open and easy to deal with as someone who is down to earth．
When we have both our feet firmly on the ground，and when we are down to earth，we do not have our noses in the air．We act honestly and openly to others．And our lives are like the ground below up—solid and strong．
【小题1】He who considers himself to be better and more important than others is likely to .
| A．have his head in the clouds | B．be easy to deal with |
| C．have a “common sense” | D．have “a big head” |
| A．“his nose in the air” | B．“go to his head” |
| C．“both feet on the ground” | D．“daydreamer” |
| A．some popular American expressions | B．how to be down to earth |
| C．why to be honest and open | D．how to deal with someone who is down to earth |
“I Went Skydiving at 84!”
As a young girl growing up in the 1930s, I always wanted to fly a plane, but back then it was almost unheard of a woman to do that. I got a taste of that dream in 2011,when my husband arranged for me me ride in a hot air balloon for my birthday. But the experience turned out to be very dull. Around that time ,I told my husband that I wanted to skydive. So when our retirement community（社区）announced that they were having an essay competition and the topic was an experience of a lifetime that you wanted to have, I decided to write about my dream.
In the essay, I wrote about my desire to skydive, stating George Brush Sr. did it at age 80. Why not me? I was just 84 and in pretty good health. A year went by and I heard nothing. But then at a community party in late April 2009, they announced that I was one of the winners. I just couldn’t believe it.
One june 11, 2009, nearly 40 of my family and friends gathered in the area close to where I would land while I headed up in the airplane. My instructor, Jay, guided me through the experience. The plane was the noisiest one I had ever been in, but I wasn’t frightened—I was really just looking forward to the experience. When we reachen 13,000 feet, Jay instructed me to throw myself out of the plane. When we first hit the air, the wind was so strong that I could hardly breathe. For a second I thought, “What have I gotten myself into?” But then everything got calmer. We were in a free fall for about a minute before Jay opened the parachute（降落伞）, then we just floated downward fo zhout five minutes. Being up in the clouds and looking at the view below was unlike anything I have ever felt—much better than the hot air ballon. I was just enjoying it.
Skydiving was really one of the greatest experiences of my life. I hope other people will look at me and realize that you don’t stop living just because you are 84 years old. If there’s something you want to experience, look into it. If it’s something that is possible, make it happen.
