Why does most of the world travel on the right side today? Theories differ, but there's no doubt Napoleon was a major influence. The French have used the right since at least the late 18th century. Some say that before the French Revolution, noblemen drove their carriages on the left, forcing the peasants to the right. Regardless of the origin, Napoleon brought right-hand traffic to the nations he conquered, including Russia, Switzerland and Germany. Hitler, in turn, ordered right-hand traffic in Czechoslovakia and Austria in the 1930s. Nations that escaped right-hand control, like Great Britain, followed their left-hand tradition.

The U.S. has not always been a nation of right-hand drivers; earlier in its history, carriage and horse traffic travelled on the left, as it did in England. But by the late 1700s, people driving large wagons pulled by several pairs of horses began promoting a shift (改变) to the right. A driver would sit on the rear (后面的) left horse in order to wave his whip (鞭子) with his right hand; to see opposite traffic clearly, they travelled on the right.

One of the final moves to firmly standardize traffic directions in the U.S. occurred in the 20th century, when Henry Ford decided to mass-produce his cars with controls on the left ( the reason was stated in a 1908 catalog: the convenience for passengers exiting directly onto the edge, especially if there is a lady to be considered).Once these rules were set, many countries eventually adjusted to the right-hand standard, including Canada in the 1920s, Sweden in 1967 and Burma in 1970.The U.K. and former colonies such as Australia and India are among the Western world's few remaining holdouts(坚持不变者).Several Asian nations, including Japan, use the left as well—though many places use both right-hand-drive and left-hand-drive cars.

1.Why did people in Switzerland travel on the right?

A. They had used the right-hand traffic since the 18th century.

B. Rich people enjoyed driving their carriages on the right.

C. Napoleon introduced the right-hand traffic to this country.

D. Hitler ordered them to go against their left-hand tradition.

2.Of all the countries below, the one that travels on the right is ______.

A. Austria　　 B. England　　 C. Japan　　 D. Australia

3.Henry Ford produced cars with controls on the left ______.

A. in order to change traffic directions in the U.S.

B. so that passengers could get off conveniently

C. because rules at that time weren't perfect

D. though many countries were strongly against that

4.According to the passage, which of the following is TRUE?

A. Before the French Revolution, all the French people used the right.

B. People in Britain and the U.S. travel on the same side nowadays.

C. The Burmese began to travel on the right in 1970.

Scientists have discovered why the Mona Lisa's expression looks so different to different people and at different times.

For centuries, art lovers and critics have been confused by and debated the Leonardo Da Vinci painting's gaze and slight smile.

But new research from the University of California, San Francisco has shed new light on the shining and seemingly changing face of the Mona Lisa.

Through experiments, they discovered that our emotions really do change how we see a neutral face.

Dr Erika Siegel and her colleagues study how our emotions change our perceptions of the world around us—even when we aren't aware that something has changed our feelings.

This relies on the modern theory of" the brain as a predictive organ, instead of a reactive one,” says Dr Siegel.

In other words, “we have a lifetime of experience and we use those experiences to predict what we are going to experience next.”

We all have one dominant eye and one more passive non-dominant one. If each eye is receiving different information, we only consciously perceive what dominant one sees. But non-dominant sights can still enter our subconscious.

They showed 43 people two sets of flashing images simultaneously, so that the dominant eye saw and registered neutral expressions, while the non-dominant eye “saw” flashes of neutral, or smiling faces, which they would only subconsciously be aware of.

After viewing the flashing faces, the researchers showed the participants options of faces and asked them to pick out which ones they had seen.

When their non-dominant eyes had seen a happy face, they were more likely to think the neutral face had actually been smiling, and the same was true for other expressions.

This means that “if you see the Mona Lisa after you have just had a screaming fight with your husband, you're going to see the painting differently,” says Dr Siegel.

“But if you're having the time of your life at the Louvre, you're going to see the mysterious smile,” she adds.

“We are the architects of our own experience. Our brain makes predictions about what it expects to see and uses information from the world to update its expectations,”Dr Siegel says.

1.What is the purpose of Dr Siegel's research?

A.To discover why people perceive the same thing differently.

B.To help appreciate the Mona Lisa.

C.To win a debate.

D.To tell a smiling face from a neutral face.

2.Which of the following is the closest in meaning to “shed new light” in Paragraph 3?

A.Made something bright. B.Provided new explanations.

C.Added light-colored paints. D.Increased amount of natural light.

3.Why did the researchers show the participants two sets of flashing images?

A.To play a game.

B.To pick out their dominant and non-dominant eyes.

C.To strengthen the effect of the non-dominant eyes.

D.To provide images of more expressions.

4.Which of the following can be the best title for the text?

A.Effects of Emotions B.Seeing Is Believing

C.A Mysterious Research D.Is Mona Lisa Smiling?
