On August 1, 2023, new rules went into effect in the United States thạt make it against the law to sell most incandescent (白炽的) light bulbs.

Incandescent light bulbs have been common since the late 1800s. They use electricity to create light by heating a metal wire, which glows. Over 90% of the electricity used by the bulbs goes into making heat — not light.

Since 2005, countries around the world have been banning incandescent bulbs. That's what's happening in the US. The new rules don't actually make incandescent bulbs illegal. They just say that light bulbs that are sold must be able to create a certain amount of light (45 lumens) with a certain amount of energy (l watt). Most incandescent bulbs can only create about 15 lumen s with I watt.

These days, the best way to replace incandescent bulbs is with LED light bulbs. These bulbs can create about 75 lumens with 1 watt of electricity. And they can last 25 or more times longer than incandescent bulbs.

Though the rule just took effect at the beginning of August, it was first created in 2007. Since then, the rule has been delayed many times, usually for political reasons. In the early 2000s, LED bulbs cost more money than they do today, and weren't nearly as good. But in recent years, people have been switching over to LED lights, even without the rule. The lights have become more and more popular, since they use less energy and save people money by lasting longer.

The new rules will also help the environment. Over the next 30 years, LED bulbs are expected to help prevent a huge amount of pollution in the US — about as much as would be used by 28 million homes in one year. That will be an imperative step in tackling the climate crisis.

(1)、Why does the author mention incandescent light bulbs in Paragraph 2?
A、To explain how they work. B、To show they used to be important. C、To show they aren't good lighting sources. D、To explain how light is usually made.
(2)、What do the new rules in America mean?
A、New incandescent bulbs will be invented. B、Using incandescent bulbs has been prohibited. C、No more incandescent bulbs will be produced. D、Incandescent bulbs should be mostly replaced.
(3)、What is shown about LED bulbs?
A、They're great replacements for incandescent bulbs. B、They're cheaper than incandescent bulbs. C、They're widely used all over the world. D、They're unknown to many Americans.
(4)、What does the underlined word "imperative" in the last paragraph probably mean?
A、Workable. B、Important. C、Interesting. D、Challenging.

    America's businesses are getting older and fatter, while many new businesses are dying in infancy.

    A study last month by the Brookings Institution found that the proportion of older firms has grown steadily over several decades, while the survival rate of new companies has fallen. In addition, young people are starting companies at a sharply lower rate than in the past.

    A new report from the National Association of Manufacturers shows a major cause: The cost of obeying government regulations has risen to more than $2 trillion (12.26 trillion yuan) annually, or 12 percent of the GDP, and this cost falls disproportionately on smaller, newer businesses.

    It's risky, difficult and expensive to start a business, and getting more so. Governments are imposing various new rules on a seemingly daily basis: health insurance, minimum wage increases and, most recently in California, compulsory paid sick days for even hourly employees. These regulations shift huge social welfare costs directly onto often-struggling small businesses, while being proportionally much less costly for larger companies.

    This is partly an unintended issue of resources—established companies can cope with new costs more easily—but it's also deliberate. For instance, big insurance companies got a seat at the table to help write Obamacare, but less politically powerful firms—like medical device manufacturers—got squeezed.

    Mature, successful corporations can employ ex-lawmakers with connections, distribute campaign contributions and even write regulations for themselves. They are also more likely to want to protect steady revenue streams than revolutionize their industry.

    Major companies that have been so ill-managed they would otherwise collapse—airlines, car companies and banks—stagger(蹒跚)on because politicians ride to the rescue with bags of taxpayer money.

    The genius of our unique system of government is the determination to protect and defend the rights of the individual over the rights of the nation. As such, the rise of a well-connected oligarchy(寡头政治)that protects big business at the expense of small business, and the established over the new, is opposite to American ideals.

    Income inequality—which is directly caused by faulty government policy—is being promoted as the reason to impose more of that bad policy. But let's be perfectly clear, we do not have a free market but one where government picks winners and losers through regulations and financial aids.

    Politics is, and always has been, about balancing competing interests seeking to benefit themselves, and that's as it should be, but the force of government should never be used to reduce competition, kill innovation or support and extend artificial monopolies(垄断)by harming the consumer, the taxpayer and the economy. Policy must breed our new and small businesses or see the as-yet undreamed of innovations that could be our bright future die in infancy.

    When the evening is coming, my dear son and I are preparing for the tape time. “Shoes on,” I remind 9-year-old Sam. “Snakes are always waiting for the chance to kiss you. But with our feet stepped into my car, we are safe.” We take blankets and cups of milk and head out to the shelter that serves as our garage. This has become our bedtime habit.

    I press “play.” A motherly voice fills the car. My mother and my aunt send us books on tape obtained from secondhand shops or rescued from the back of drawer. Maybe no one in England lays cassettes anymore, but I still love them.

    Sam rests on his seat. He's sitting in the front seat. I am listening to the cassette. But I am also thinking. In a month's time, my boy will be 10. Next year, he will be 11. And so it will go on, until he leaves me and his father and his sister to live out his own stories— as it is only right and proper he should.

    Will he think back to the times when he sat in the dark in a car in Africa, listening to tales of Wales in World War Ⅱ, the finest lady detective of Botswana, or a country he has visited, and tells me he finds them “very interesting”? Will he think , when he is grown-up, the poor mum always makes the ancient tape player which is out of date work?

    I like to believe that he will recall those wonderful moments. By then, perhaps, my child will realize a deep love of sharing and understanding by listening to the old tape player. I hope Sam will think that these evenings we spend in the car are a story themselves. It is his own first chapter. In time my boy will ease off the hand brake and roll out into the world. Until then, I'll keep pressing “play”.

    Life-Changing Science Discoveries

    Here's a look at some discoveries that have changed the world. It's impossible to rank their importance, so they're listed in the order they were discovered

Micro-organism

    Before French chemist Louis Pasteur began experimenting with bacteria in the 1860s, people did not know what caused disease. He not only discovered that disease came from micro-organisms, but also realized that bacteria could be killed by heat and disinfectant(消毒剂). This idea caused doctors to wash their hands and disinfect their instruments, which has saved millions of lives.

Penicillin

    Antibiotics are powerful drugs that kill dangerous bacteria in our bodies that make us sick. In 1928, British Alexander Fleming discovered the first antibiotic, penicillin, which he grew in his lab. Without antibiotics, infections like strep throat could be deadly

DNA

    On February 28, 1853, James Watson of the United States and Francis Crick of England made one of the greatest scientific discoveries in history. The two scientists found the structure of DNA. Our genes are made of DNA and determine how things like what color hair and eye we'll have. In 1962, they were awarded the Nobel Prize for this work . The discovery has helped doctors understand diseases and may someday prevent some illnesses like heart disease and cancer.

X-rays

    Wilhelm Roentgen, a German physicist, discovered X-rays in 1895. X-rays go right through some substances, like flesh and wood, but are stopped by others, such as bones and lead. This allows them to be used to see broken bones or explosives inside suitcases, which makes them useful for doctors and security officers. For this discovery, Roentgen was awarded the first-ever Nobel Prize in Physics in 1901.
