In spite of the uncertainty of the economy, the movie industry has been stricken by a box-office outburst. Suddenly it seems as if everyone is going to the movies, with ticket sales this year up 17.5 percent, to $1.7 billion.

And it is not just because ticket prices are higher. Attendance has also jumped, by nearly 16 percent. If that pace continues through the year, it would amount to the biggest box-office increase in at least two decades.

Americans, for the moment, just want to hide in a very dark place. People want to forget their troubles, and they want to be with other people. Helping feed the outburst is the mix of movies, which have been more audience-friendly in recent months as the studios have tried to adjust after the discouraging sales of more serious films.

As she stood in line at the 18-screen Bridge theater complex here on Thursday to buy weekend tickets for “Jonas Brothers: The 3D Concert Experience,” Angel Hernandez was not thinking much about escaping reality. Instead, Ms. Hernandez, a Los Angeles parking lot attendant and mother of four young girls, was focused on one very specific reality: her wallet.

    “Spending hundreds of dollars to take them to Disneyland is ridiculous right now,” she said. “For $60 and some candy money I can still be a good mom and give them a little fun.”

A lot of parents may have been thinking the same thing Friday, as “Jonas Brothers” sold out more than 800 theaters, and was expected to sell a powerful $25 million or more in tickets.

The film industry appears to have had a hand in its recent good luck. Over the last year or two, studios have released movies that are happier, scarier or just less

depressing than what came before. After poor results for a rush of serious dramas built around the Middle East, Hollywood got back to comedies.

Which of the following is not a reason for the improvement of the movie industry?

A. A growing number of people are going to the cinema.

B. People are richer with the development of economy.

C. More comedies are made than serious films.

D. People have to pay more to watch a movie.

On numerous drives throughout my childhood, my mother would suddenly pull over the car to examine a flower by the side of the road or rescue a beetle (甲虫) from certain tragedy while I, in my late teens and early twenties, sat impatiently in the car.

    Though Mother’s Day follows Earth Day, for me, they have always been related. My mom has been “green” since she became concerned about the environment. Part of this habit was born of thrift (节俭). Like her mother and her grandmother before her, Mom saves glass jars, empty cheese containers and re-uses her plastic bags.

    Mom creates a kind of give-and-take relationship with wildlife in her yard. She knows to pick the apples on her trees a little early to fend off the bears and that if she leaves the bird feeders out at night, it’s likely they’ll be knocked down by a family of raccoons (浣熊). Spiders that make their way into the house are captured (捕获) in a juice glass and set loose in the garden.

    I try to teach my children that looking out for the environment starts with being aware of the environment. On busy streets, we look for spent (开败的) dandelions (蒲公英) to parachute; we say hello to neighborhood cats and pick up plastic cups and paper bags. This teaching comes easily, I realize, because I was taught so well by example. Mom didn’t need to lecture; she didn’t need to beat a drum to change the world. She simply slowed down enough to enjoy living in it and with that joy came compassion and an instinct (本能) for preservation.

    I am slowing down and it isn’t because of the weight of my nearly forty years on the planet, it is out of my concern for the planet itself. I’ve begun to save glass jars and re-use packing envelopes. I pause in my daily tasks to watch the squirrels race each other through the palm (棕榈树) leaves above my porch (门廊).

    Last summer, in the company of my son and daughter, I planted tomatoes in my yard. With the heat of August around me, I ate the first while sitting on my low wall with dirt on my hands. Warm from the sun, it burst on my tongue with a sweetness I immediately wanted to share with my mom.

We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.

The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has-discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a ＄10,000 prize, a ＄20,000 scholarship, and a chance to revolutionize a major environmental issue.

Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.

With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.

The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.

“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” Said Daniel Burd.
