Dear Reader:

I receive many letters from children and can't answer them all -- there wouldn't be time enough in a day．That is why I am sending you this printed reply to your letter．I'll try to answer some of the questions that are commonly asked.

Where did I get the idea for Stuart Little and for Charlotte's Web? Well, many years ago I went to bed one night in a railway sleeping car, and during the night I dreamed about a tiny boy who acted rather like a mouse．That's how the story of Stuart Little got started.

As for Charlotte's Web, I like animals and my barn is a very pleasant place to be, at all hours．One day when I was on my way to feed the pig, I began feeling sorry for the pig because, like most pigs, he was doomed to die．This made me sa

So I started thinking of ways to save a pig's life．I had been watching a big grey spider at her work and was impressed by how clever she was at weaving．Gradually I worked the spider into the story that you know, a story of friendship and salvation(拯救) on a farm．Three years after I started writing it, it was publishe

(I am not a fast worker, as you can see.)

Sometimes I'm asked how old I was when I started to write, and what made me want to write．I started early – as soon as I could spell．In fact, I can't remember any time in my life when I wasn't busy writing．I don't know what caused me to do it, or why I enjoyed it, but I think children often find pleasure and satisfaction is trying to set their thoughts down on paper, either in words or in pictures．I was no good at drawing, so I used words instea

As I grew older, I found that writing can be a way of earning a living.

Some of my readers want me to visit their school．Some want me to send a picture, or an autograph, or a book．And some ask questions about my family and my animals and my pets．Much as I'd like to, I can't go visiting．I can't send books, either – you can find them in a bookstore or a library．Many children assume that a writer owns (or even makes) his own books．This is not true – books are made by the publisher．If a writer wants a copy, he must buy it．That's why I can't send books．And I do not send autographs – I leave that to the movie stars．I live most of the year in the country, in New Englan

From our windows we can look out at the sea and the mountains．I live near my married son and three grandchildren.

Are my stories true, you ask? No, they are imaginary tales, containing fantastic characters and events．In real life, a family doesn't have a child who looks like a mouse; in real life, a spider doesn't spin words in her we

In real life, a swan doesn't blow a trumpet．But real life is only one kind of life – there is also the life of the imagination．And although my stories are imaginary, I like to think that there is some truth in them, too – truth about the way people and animals feel and think and act.

Yours sincerely,

White

Dear Cary,

I’m writing because I’ve understood you’ve struggled with alcoholism(酗酒)．I’ve been fighting mine ever since I went through 9-11．After that，I’ve been more or less useless professionally –I’m a lawyer–and have had to resign from my job because I was discovered passed-out drunk in front of my computer.I’ve taken some medicine and it has helped somewhat.I can manage about a month without drinking，but after that I end up having a crazy stage where nothing matters except drinking．After a week or so of heavy drinking，I start having nightmares of people jumping.After that，it’s a week of not being able to get out of bed.

I was supposed to travel to a conference but didn’t make it because I got so drunk at the airport that I fell down on my face and spent the rest of the day in the emergency room. I have been hiding from my family since then．Fortunately they won’t be expecting me to come back for a week or so.Otherwise, they would notice the bump on my forehead and two black eyes．

I don’t really know what I’m asking you．Cary,I need a way out that doesn’t involve causing pain to my family．I’m taking medicine，but I still have these attacks every few months．If there’s alcohol in the house，I can’t stay away from it．It seems that this will never end. I’m afraid of what  will happen if something bad happens，like a family member dying,or getting fired again．

Thanks for reading．

Yours

December 15, 2014

Dear Alfred，

I want to tell you how important your help is to my life.

Growing up, I had people telling me I was too slow, though, with an IQ of 150+ at 17, I’m anything but stupid. The fact was that I was found to have ADHD(注意力缺陷多动障碍). Anxious all the time, I was unable to keep focused for more than an hour at a time.

However, when something did interest me, I could become absorbed. In high school, I became curious about the computer, and built my first website. Moreover, I completed the senior course of Computer Basics, plus five relevant pre-college courses.

While I was exploring my curiosity, my disease got worse. I wanted to go to college after high school, but couldn’t. So, I was killing my time at home until June 2012 when I discovered the online computer courses of your training center.

Since then, I have taken courses like Data Science and Advanced Mathematics. Currently, I’m learning your Probability course. I have hundreds of printer paper, covered in self-written notes from your videos. This has given me a purpose.

Last year, I spent all my time looking for a job where, without dealing with the public, I could work alone, but still have a team to talk to. Luckily, I discovered the job—Data Analyst—this month and have been going full steam ahead. I want to prove that I can teach myself a respectful profession, without going to college, and be just as good as, if not better than, my competitors.

Thank you. You’ve given me hope that I can follow my heart. For the first time, I feel good about myself because I’m doing something, not because someone told me I was doing good. I feel whole.

This is why you’re saving my life.

Yours,

Tanis

1. Why didn’t Tanis go to college after high school?

A. She had learned enough about computer science.

B. She had more difficulty keeping focused.

C. She preferred taking online courses.

D. She was too slow to learn.

2. As for the working environment, Tanis prefers _________.

A. working by herself

B. dealing with the public

C. competing against others

D. staying with ADHD students

3.Tanis wrote this letter in order to _________.

A. explain why she was interested in the computer

B. share the ideas she had for her profession

C. show how grateful she was to the center

D. describe the courses she had taken so far

Amazingly, US crime figures have been falling for 20 years now．Of course, the big question is, why? And can any lessons be learnt?

One reason could be the fall in the demand for the drug crack．During the 1980s, drug-related crimes soared, mostly caused by desperate crack users．However, according to professor Blumstein, co-author of The Crime Drop in America, news of the dangers of crack use caused its decrease and led to a fall in the number of drug-related crimes.

Some say that the adoption of a zero-tolerance policy in many cities has helped lead to a fall in crime．In New York City, for example, mayor Rudy Giuliani imposed strict and automatic punishments for all crimes, including minor offences such as graffiti and littering．Many believe this has had a very strong deterrent(威慑的) effect.

Another reason could be smarter policing strategies．Anti-theft measures and educating the community about car theft has helped see a drop in crimes in many areas．Also, the use of crime mapping schemes that can discover identify crime peaks in different parts of the city has helped police target hotspots.

Another reason could be that more criminals are now behind bars．Sociologist John Conklin (from Tufts University) says a significant factor behind the fall in crime in the 1990s is the simple fact that many criminals are in jail．In his book Why Crime Rages Fell, he says sentencing was merciful in the 1960s and 1970s, when crime rose．But then more prisons were built and more offenders were imprisoned.

Some have linked the fall in violent crime to a decline in children’s exposure to lead in petrol．Jessica Wolpaw Reyes says, “Even low to moderate levels of exposure can lead to behavioral problems, reduced IQ, hyperactivity(多动症) and youth crimes．You can link the decline in lead between 1975 and 1985 to a decline in violent crime 20 years later.”

Others say that the drop in crime has something to do with birth rates．According to statistics, birth rates peaked between 1957 and 1961, and the proportion of men in the US in their late teens and early 20s (the so-called “criminal age”) was highest in the late 70s and early 80s．However, as time went on, the proportion of people in this age group decrease

Others claim that videogames have helpe

A recent study has suggested that these games are keeping young people off the streets and therefore away from crime．Advocates of this argue that any effects the games may have in encouraging violent behavior is offset by the fact that the games keep potential criminals indoors and in front of the television．

Some argue that the widespread use of camera phones makes some criminals think twice before committing a crime and getting filmed doing it．Also, many believe that the mass use of CCTV has also had an effect.

Finally, some say that petty theft just isn’t worth it any more．The resale value of second-hand goods such as televisions, cameras or clothes is now so low (or even non-existent) that most people see no point in stealing．

So, what do you think?

1.By writing this article, the writer intends to tell us _____.

A．the amazing fact that US crime figures are going down

B．the recent statistics showing that crime rates are falling in the US

C．the answers to the question why US crime figures are falling

D．the special policies adopted by the US police that help a drop in crime

2.“Why Crime Rates Fell” is mentioned in the article to tell readers that _____.

A．drug crack can be extremely dangerous

B．crime mapping schemes help the police discover criminals

C．criminals should be strictly sentenced

D．children shouldn’t be allowed to contact lead

3.The sixth reason mentioned in the article implies that _____ tend to commit crimes．

A．children

B．young people

C．the poor

D．crime victims

4.The underlined word “offset” most probably mean _____.

A．reduced

B．caused

C．imposed

D．demanded

请认真阅读下列短文，从短文后各题所给的A、B、C、D四个选项中，选出最佳选项。

Everyone procrastinates．We put things off because we don’t want to do them, or because we have too many other things on our plates．Putting things off – big or small – is part of being human．But procrastination does have consequences．When your procrastination leaves you feeling discouraged, it is time to take action, and one of the best ways to get rid of it is to make an un-schedule。

An un-schedule is a weekly calendar of all the ways in which your time is already accounted for．You consider not only your timed commitments such as classes and meetings, but also your untimed activities such as meals, exercise, time with friends, and the like．Once you have made your un-schedule, you may be able to see your time is often filled with more activities than you realize, for instance, that you really don’t have five hours to spend writing on the night before your paper is due．Procrastinators’ views of time tend to be unrealistic, and the un-schedule can help you outline a realistic plan．By planning accordingly, you will not only get a better night’s sleep, you may also end up with a better paper．

The un-schedule might also be a good way to get started on a larger project, such as a term paper or an honors paper．You may think that you have “all semester” to get the writing done, but if you really map out how much time you have available to write on a daily and weekly basis, you will see that you need to get started sooner, rather than later．In addition, the un-schedule may reveal especially busy weeks or months, which will help you budget time for long-term projects．

Perhaps most importantly, the un-schedule can help you examine how you spend your time．You may be surprised at how much time you spend watching television, and decide to make a change．It’s especially important that you build time for fun activities into your un-schedule．Otherwise, you will procrastinate in order to steal time for relaxation．

You can also use the un-schedule to record your progress towards your goal．Reward yourself for your small successes．Seeing what you’ve achieved will help you reinforce (强化) the productive behavior, and you will feel more motivated in the following process．

As you explore ways to conquer procrastination, don’t expect overnight transformation．You developed the habit over a long time; you aren’t going stop magically．But you can change the behavior, bit by bit．If you start to make an un-schedule now, you will eventually develop new habits．

1.From Paragraph 2, we can know that procrastinators __________．

A．usually have sleeping problems

B．tend to be unrealistic in daily life

C．spend more time in doing exercise

D．often fail to notice untimed activities

2.Which of the following statements best reflects an un-schedule?

A．“Now I have more time for fun.”

B．“I can start my big project later.”

C．“I’ll treat myself to a movie for my progress.”

D．“I’m going to have more time to finish my paper.”

3.According to the writer, people need to make an un-schedule because of their _．

A．interests in doing things differently

B．determination to try out new things

C．inability to manage time properly

D．lack of concentration on a project

Wind turbines are efficient sources of cheap energy but also a source of concern as their huge spinning blades (叶片) frequently kill birds and bats. A new type of wind generator developed in Spain offers a creative solution to that problem.

In 2002, Spanish inventor David Yanez saw a short film about the Tacoma Narrows Bridge in the U.S., collapsing in strong wind. It was a vivid example of the powerful vibrations wind can create when it blows past a long pole, such as a car antenna or even a stick of bamboo. It gave him the idea for a new type of wind-energy generator.

“The initial philosophy or spirit was to create a generator of dreams that had all the qualities one would want: It should be as cheap as possible, need as little maintenance as possible, the setup as simple as possible,” he said.

Yanez and his friend Raoul Martin took the idea to an engineering firm, where they were told it would never work. Undiscouraged, they started experimenting on their own in a small wind tunnel they built.

Good initial results were repeated by a larger working model called Vortex (涡旋) installed in a nearby field. “What we have is a mast (桅杆), which is the top piece and acts as a blade,” Yanez said. “It’s constructed from the same material as a conventional generator, and what it does is it oscillates (振荡), transmitting the oscillation to a conventional alternator, which by its own oscillation converts the wind’s energy into electric energy.”

Yanez said the output of the 6-meter-tall generator, and even that of smaller models, was better than expected. The Vortex creates about 30 percent less energy than a comparable bladed wind turbine, but it is lighter and cheaper to build and maintain. It is made mostly of reinforced plastic and has very few moving parts. Also, it does not create noise and—even more important for many environmentalists—it does not present a threat to passing birds.

The current prototype works at wind speeds ranging from 1.5 to 7 meters per second. The inventors say the next step is building a 12.5-meter tall bladeless generator with a 4-kilowatt capacity that could power small businesses or individual homes, or provide supplemental power to a main grid. The commercial version of the Vortex Bladeless generator should be ready for the market by 2017.

1.The author mentions a short film about the Tacoma Narrows Bridge to show ________.

A. what the initial philosophy or spirit was

B. what inspired Yanez to create the generator

C. how the bridge was destroyed in strong wind

D. how wind creates powerful vibrations

2.What do we know from the passage?

A. The original idea was considered as practical in an engineering firm.

B. Yanez and Martin’s initial tests by themselves proved to be successful.

C. The material for constructing the mast is different from that of the past.

D. The new generator is better at creating energy than a comparable bladed one.

3. What would be the best title for the passage?

A. Bladeless wind-power generator is friendly to birds.

B. Wind turbines are efficient sources of cheap energy.

C. A new generator will come onto the market by 2017.

D. Yanez has made a generator for the benefit of people.
