     Imagine a world without trees. What if the rainforests and all of the plants and animals suddenly did not exist? In 1962, Gaylord Nelson decided something needed to be done to protect the environment. The work that he began led to what we now know as Earth Day.

     Mr. Nelson realized very few people were concerned about environmental problems. He then went to Washington, D.C., where he hoped to persuade President Kennedy to take a stand on environmental problems. It wasn’t long before President Kennedy agreed that action should be taken. The president set out on a five-day, eleven-state conservation(保护自然资源) tour in September of 1963. Although Kennedy’s tour was not a success, Mr. Nelson was not ready to give up.

     Mr. Nelson continued to speak to people across 25 states about the importance of the environment. Although his point of view began to be accepted by most people, politicians (政治家) were still not listening.

     In September of 1969, at a meeting in Seattle, Mr. Nelson announced that he would hold a nationwide demonstration (游行) for environmental protection the next spring. On April 22, 1970 (the first Earth Day), more than 20 million Americans took part in the demonstration. It made people sit up and pay attention to environmental problems. One year later, the UN signed(签署) an announcement making Earth Day an official international holiday. Now, Earth Day is celebrated each year around the world, and more and more people begin to realize the importance of protecting the environment.

b. Mr. Nelson went to Washington, D.C.

c. The first Earth Day was celebrated

d. President Kennedy set out on a conservation tour.

A. b-a-d-c     B. b-d-a-c     C. a-b-d-c     D. a-b-c-d

Few of us make money by losing sleep.But three graduate students at Brown University in Providence built a company around sleep deprivation (睡眠不足).

       Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schools.They began thinking about ways to sleep better.They discovered they weren't alone in burning the midnight oil.Around 20% of Americans get less than six hours of rest a night.

       The friends imagined a smart alarm clock that could track how much time people spend in the most restorative (有回复作用的) stages of the sleep cycle: REM (rapid eye movement) and deep sleep.What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors and scientists.

       Their company, Zeo, based in Newton, Mass, launched its product in June, 2009.The Zeo device uses a headband with tiny sensors (传感器) that scan your brain for signs of four sleep states- REM, light, deep and waking sleep.The smart alarm clock displays a graph of your sleep pattern and wakes you as you're not in REM sleep (which is when you're least groggy).In the morning you can upload the data to the company's Web site, and so track your sleep over time.Most of the feedback comes in the form of Zeo's ZQ score showing how well you've slept.

       "Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO.

       Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm.

       For now the company is selling Zeo online only.Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels.

Who will support Zeo?

       A.People full of imagination.          B.People suffering sleeping problems.

       C.People having access to the Internet. D.People having bad lifestyles.

Why did the three graduate students imagine a smart alarm clock?

       A.To wake them up on time in the morning.

       B.To earn enough money for their study.

       C.To improve the quality of people's sleep.

       D.To enjoy their life while working at night.

To design the Zeo device, the three graduate students ____.

       A.spent much time and money           B.were widely supported by scientists

       C.worked by themselves all the time       D.attracted many investors

What can we know from the passage?

       A.Zeo has a direct effect on users' lifestyles.

       B.It needs more personal efforts to make Zeo function better.

       C.A large quantity of Zeo devices have been sold in Australia.

       D.Consumers can go to the Zeo company to purchase Zeo in person.

  Imagine yourself on a boat looking out at the horizon and all you can see is the water meeting the sky with no land in sight and you are sailing straight ahead to meet the world. Jesse Martin does not have to imagine: he is living in it.
On Dec. 7, 1998, at 17 years old, Jesse set sail from Melbourne, Australia on his boat, attempting to become the youngest person to sail alone and nonstop around the world. He sailed south of New Zealand, through the South Pacific, around South America, north on the Atlantic, back south past Africa, through the Indian Ocean and back to Melbourne.
Even as a young child, Jesse had been an adventurer who traveled all over Europe and Asia with his parents. Born in Munich, Germany in 1981, he moved to Australia with his family when he was only two years old. They moved close to a rainforest in Cow Bay, about 3500kms north of Melbourne, where they built a small house with no electricity or running water. Jesse grew up at the beach enjoying the outdoors to its fullest.
At 14, he sailed for the first time with his father and brother, Beau. It was after this trip that he began to dream about sailing around the world.
Jesse’s family played an important role. “I was made to believe I could do anything.” he says. Although, he says, there were others that were not so encouraging or supportive, “People that I looked up to, respected and trusted told me I couldn’t. Thankfully, I trusted myself. There were people that said that the boat couldn’t be ready by the time I had to leave.” However, through perseverance and belief in himself he was able to do what many told him was impossible.
On Oct.31, 1999, more than 10 months after he set sail, Jesse Martin went down in history as the youngest person to sail around the world alone, nonstop and unassisted.

With the aid of a mechanic, Fred Young ,Goldman designed the first shopping cart based on the folding chair.Wheels were placed where the bottoms of the chair legs were. In place of the chair seat, Young and Goldman , placed two metal baskets on top of each other. This cart could be stored by folding it up like a folding chair.
At first there was a bit of difficulty getting the public to accept shopping carts.Men thought using them was effeminate(女人气的)while younger women considered the use of the shopping carts to carry products around to be somewhat unstylish.Goldman solved this problem by hiring men and women models to use shopping carts in his stores.In addition,store     greeters instructed customers in how to use the shopping carts.In short order,the shopping carts became incredibly popular because it made shopping much easier for customers.By 1940 the popularity of shopping carts had grown to such an extent that there was a 7 year waiting list in store orders for new shopping carts.
