_______ good use of learning resources such as the website and library, and you will make great progress.

Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.

1. Most historians hold that the Chinese invented fireworks in the 9th century when they

discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.

2. In May of 1886, a law led John Pemberton, a pharmacist（药剂师）, to rewrite the formula(配方) for "Pemberton’s French Wine Coca,” his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world –wide drink came into being.

3. During World War II, scientists at the University of Birmingham invented the magnetron—an important heat-producing part of the microwave oven(微波炉). While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.   

The right time order of the three inventions, according to the passage, should be_________.

A. fireworks, the microwave and Coca-Cola

B. fireworks ,Coca-Cola and the microwave

C. Coca-Cola , fireworks and the microwave

D. the microwave, Coca-Cola and fireworks

Percy Spencer found the microwave efficient in cooking when he was _______.

A. looking for a way to melt his chocolate

B. trying to know how a magnetron could cook

C. working to know how the magnetron works

D. asked to invent a restaurant microwave oven

What can we learn from the above invention stories? 

A. Experiments make great inventors of our time.     

B. Nothing is impossible if one tries each day.

C. Inventors come out of hard work at any time.

D. A small incident may lead to a great invention.

What’s the best title for the passage?

A. What great inventions they are!               B. Inventions from Three Countries.

C. Stories of Accidental Inventions.          D. The Human Inventions of time.

The Happiest Cities On Earth

If you’re looking for a cheery destination for your next vacation, consider these four spots and get ready to take notes on how to really live the good life.

Singapore

    With one of the highest population densities（密度）in the world and residents known for being workaholics, it’s hard to imagine the city-state of Singapore having one of the happiest populations on earth. And yet in a recent survey, 95% of them said they were either very happy or quite happy.

They give their city high marks for cleanliness and safety—subways are pristine (洁净的) and unfailingly arrive on time, and police are seen as helpful and good at their jobs. What’s more, they feel they can count on their neighbours—all 5.1 million of them.

Arhus, Denmark

The residents of Arhus cheerfully part with 68% of their income in taxes, knowing that in return they will be guaranteed free healthcare, free daycare, and a top-notch (第一流的) education for their children.

An energetic city of 300,000 with a lively cultural scene and a diverse number of religions represented, the sense of equality (the range in incomes is narrow), as well as easy access to the nearby sea and surrounding countryside, make Arhus seem more like a small town.

San Luis Obispo, CA

According to a 2008 Gallup-Healthways study, people who live in San Luis Obispo are more likely than residents of other U.S. cities to smile and experience joy and are less likely to experience pain or depression. About 64,000 of the 260,000 people in the greater metropolitan area (都市区), located halfway between Los Angeles and San Francisco, volunteer at over 11,000 non-profit organizations.

Few journeys to work are longer than 10 minutes (one reason its members rank in the upper third for job satisfaction), so “it’s easy to be involved,” resident Pierre Rademaker said. Business signs are unobtrusive (不显眼的) by law, fewer than 11% of residents smoke—the lower rate in the U.S.—there are lots of bike lanes, and the city’s plaza draws crowds of people for free concerts on summer Fridays. What’s not to love?

Monterrey, Mexico

The people of Monterrey don’t enjoy high household incomes or access to good healthcare. Instead, there’s a profound sense of gratitude for the new political freedom enjoyed since the oppressive Institutional Revolutionary Party lost power in 2000—the first time in nearly a century—as well as an emphasis on social life over work.

Another reason Monterrey residents may be so happy is their faith in God and family, and their ability to tough it out through bad times.

“We laugh at sickness, poverty and even death,” says Basanez, a political scientist who lives in Monterrey. “We even have a holiday to celebrate death. November 2, the Day of the Dead, is one of the biggest holidays of the year.”

1.According to the passage, what do the residents in the four cities have in common?

A. All the residents can make great fortunes by working hard.

B. The residents there are mostly educators. 

C. All the residents enjoy enough material wealth.

D. The majority of the residents are satisfied with their current life.

2.According to the passage, we can infer that _______.

A. the people of Singapore expect their neighbours to come to their help when necessary

B. the people of Monterrey even observe one’s death on a special day of a year

C. the residents of Arhus happily pay 68% of their income for their children’s education fee

D. the people who live in San Luis Obispo have job satisfaction because they can enjoy good working conditions

3.According to the passage which of the following statements is NOT TRUE?

A. The people of Monterrey didn’t enjoy political freedom until 2000.

B. The residents in Singapore feel happy because of its low population density.

C. The people of San Luis Obispo can enjoy free concerts in summer.

D. Arhus is handy to the seaside and countryside.

4.What can we learn from the underlined part “the sense of equality”?

A. The residents of Arhus have no racial discrimination.

B. Arhus is considered as a family sharing everything with each other.

C. There is no wide gap between the rich and the poor in Arhus.

D. The residents of Arhus can depend on their neighbours to help.
