If you haven’t already, you too should switch to the latest eco-friendly, energy-efficient, energy-saving LED (Light Emitting Diode) lighting. As the world becomes more focused on green issues, everyone should do their part in practicing energy efficiency, recycling, cutting down their CO2 emissions and much, much more. One of the most successful campaigns that started in Australia is the now world-famous“Earth Hour”. 2.2 million of Sydney’s residents turned off their lights for an hour in a mass attempt to save energy. The following year, the same idea was adopted by a whole host of different cities.

This is a great example of a campaign to promote eco-friendly options and energy efficiency. But while it clearly raises awareness, it is not a long-term solution to energy saving across the developed world. A long-term solution can be found in the form of switching to LED lighting rather than the traditional halogen lights(卤光灯) found in a typical home.

Put simply, LED lighting is the future of lighting. LED lamps use up only a fraction of the energy pared to that of regular lamps. They also produce a quality flicker-free light, and will last longer than a regular light with 50,000 hours being realistic. Not only are they longer lasting and more energy-efficient with no sacrifice in light quality, but they may quickly become a possible substitute (替代物) for regular lamps that have been previously installed by homes and businesses.

An ordinary 50 watt low-voltage halogen light on for 4 hours a day would cost $ 25 per year to run. With a life span of around 3,000 hours it will typically stop working at the two-year mark. compared with the regular one, an LED light of 50 watts operating for the same period will cost roughly $ 6 per year to run and last 50,000 hours. That means it won’t have to be replaced for 24 years! It really is a no brainer to switch to energy-saving LED lighting. Plus, you will be doing your bit for the environment by being more eco-friendly.

If you’ve ever owned a chimney, you know that it can get pretty dirty. There’s a whole lot of soot(烟灰) that gets stuck on the inside. That stuff has to get cleaned, or you could have a serious fire risk. While nowadays we have easier ways of doing this dirty job, in the way back days somebody used to climb up the chimney and clean all that soot. And the thing is, not just anybody could do it.

You had to be really small to fit up in the chimney, so they used to give the task to kids – some as young as four or five years old. They worked for their boss known as a master-sweep. They were often covered in soot, and were very likely to get burned. They often developed what became known as soot wart, a form of cancer.

Are your unfairness bells ringing? William Blake’s certainly were. The physical dangers and widespread unfairness of the chimney-sweeping job really stuck in his throat, so much so that he wrote not one, but two poems called “The Chimney Sweeper”.

The first poem (the one we’re discussing here)was published in 1789 in a book called Songs of Innocence. These little poems took children and the joys of childhood innocence as their subject. As you’ve probably guessed by now, many of the poems in Songs of Innocence, like “The Chimney Sweeper”, are about the ways in which childhood innocence is destroyed by unkind old adults. For Blake, innocence is, in many ways, a total joke. It doesn’t exist, because it’s always taken away by the realistic world – chimney-sweeping, death, poverty, etc.

What does a five-year-old chimney sweeper in 18th-century England have to do with you? More than you might think. It is reported that 150 million kids are in child labor in developing countries. Many of them work long hours and face dangerous health risks. Like Blake’s chimney sweeper, these kids are not even given a chance at innocence because experience keeps getting in the way.

1.Which of the following can best describe the chimney-sweeping job?

A. Easy and interesting. B. Dirty and dangerous.

C. Pleasant and well-paid D. Challenging and creative.

2.Why did Blake write two poems called “The Chimney Sweeper”?

A. He was very interested in the job.

B. He had much experience in the job.

C. He considered the job very important.

D. He felt deeply sorry for the kid workers.

3.How did Blake look at the realistic world?

A. Thankfully B. Regretfully C. Doubtfully D. Negatively

4.In the last paragraph, the writer explains ________.

A. the realistic meaning of “The Chimney Sweeper”

B. the great influence of Blake’s Songs of Innocence

C. why child labor still exists in developing countries

D. why chimney-sweeping becomes unnecessary today

D

As thousands of communities in the USA — especially in the South — became booming gateways for immigrant families from Central and South America during the 1990s and the early years of the new century, public schools struggled with the unfamiliar task of serving the large numbers of English learners arriving in their classrooms.

Education programs needed to be built from scratch. “We had no teaching resources suitable for English learners here before. We had to develop them all ourselves,” a Texas principal said. Throughout the country, districts had to train their own teachers to teach English to non-native speakers or recruit (招聘)teachers from elsewhere. School staff members had to figure out how to communicate with parents who spoke no English.

But even as immigration has slowed or stopped in many places, and instructional programs for English-learners have matured, serving immigrant families and their children remains a work in progress in many public schools, especially those in communities that are skeptical, or sometimes unwelcoming, to the newcomers. One of the biggest challenges educators face, is communicating effectively with parents who don’t speak English — an issue that, in part, has contributed to recent complaints of discrimination by Latino students in some cities.

“The parents’ role is very important for the success of these students, but it's also one of the most difficult things we’ve had to tackle(处理),” said Jim D. Rollins, the president of the Springdale school district, where the 19,000-student school system has gone from having no English-learners 15 years ago to more than 7,500 now. “You have to make it a priority and work on it, work on it, and work on it.”

Aside from the practical challenges, such as finding bilingual (会说两种语言的) staff members, guiding districts through such dramatic changes requires school leaders to bridge difficult political and cultural divides. For school leaders in the South, especially in the last few years, this difficult job has been made harder still by the negative attitudes of some locals towards immigrants.

1.According to the passage, what is the problem that public schools are facing?

A. Handling more cases from the immigrant Mexican communities.

B. Offering services to immigrant families in the southern states.

C. Offering enough communicative lessons to immigrant parents.

D. Providing education for non-native English learners.

2.The underlined part “built from scratch” (in Paragraph 2) probably means “________”.

A. completely new

B. painful to make

C. based on past experience

D. constructed gradually

3.What do we know about the immigrant parents?

A. Many of them cannot speak English.

B. Most of them think education is not important.

C. Some of them feel skeptical about the local community.

D. Few of them have attended American schools.

While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence.

For their study, biologist Corson Miller and his team exposés eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry.

Interestingly, the dogs were not provided with the entire face.Some dogs were show Ti only upper halves while the others observed lower halves.That's because the scientists believe humans show their eruptions on their equities face.

After some training ill.e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions.

They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear.In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed.

The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly.Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner.

1.How did the scientists conduct the experiment?

A.By leaving dogs to women who are either happy or angry.

B.By mixing the selected dogs together.

C.By rewarding only half of the dogs touching the screen.

D.By showing digital pictures of women's happy or angry faces.

B.They found it hard to tell the moods on the faces of a different gender.

C.They found it easy to tell the emotions on the entire -face.

What I like to advise people is to find out what it is that makes them happy. What do you love to do? If you truly love what you do just go ahead and try to make a living by doing it. People will throw money at you to do it. But you will always have to work hard at it. I have to draw every single day of my life. I have to draw about 20 ideas. My advice is to put aside a certain amount of time every day and make you draw or whatever, especially when you don’t feel like it. Only in this way will you be able to perfect your talent.

The first step you take is to go to your local library and ask for the publications issued in the current years. When you get these publications, try to find the names of the top people concerned and their presidents. After you find these, write down their names and addresses. Keep this list and update it every year. Next thing you want to do is to create at least 40 cartoons. Get a grid(格子) from one of the strips in the newspapers, enlarge it to whatever size you wish and draw inside this grid. Now take the best 20 of your ideas and make them into finished pieces. To do this, you would want to copy them in ink because if you were a professional cartoonist, that was what you should do. Now you can reduce the size of the finished cartoons to fit onto a regular comic’s page. By comparing yours with the others already in print, it gives you a good idea of clarity to your cartoon.

The next step is to write letters to presidents of the publication. In the letters, explain who you think would read your work, or in other words, what group do you think you would target. After you complete these, send all of your information enclosed with letters in the appropriate envelope.

Now as soon as you send out these letters, start to create a brand new strip with all new characters. Don’t get married to one idea because if your idea gets turned down then you will give up. And always remember. If you receive a rejection from any of them, keep in mind that you are working on something better. You will be working on something new and more exciting and the rejection letter will not have any impact. With this in mind…
