People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.

In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. “Today we’re looking at science fiction becoming tomorrow’s reality—the driverless car.” The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the US government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.

“Cars have become much more fuel-efficient, and new electronic features are making Hondas safer,” said Angie Nucci of Honda America. “A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes.” Other safety features include warning systems on the front and the sides of the cars. These systems help drivers, but don’t replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.

“By taking out drivers, you also remove most risks of an accident,” Kendall said. He said consumers, however, may be unwilling to lose control. “It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first.”

Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.

【1】Sometime early in the next century, human beings will move into habitats on Mars. They will live there for about a year, and then will be replaced with another set of pioneers. The establishment of this base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.

【2】We already know that Mars is like the earth in many ways: general size; presence of water; length of day; range of temperatures. These similarities have caused many people to consider a century-long project: to terraform Mars. Terraforming means changing a planet’s surface so that Earth’s life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists.

【3】Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth. But it will take at least 300 years.

【4】Some people think that such a project is too huge for humans to accomplish, but there are very good reasons to make the attempt. The earth now contains some 7 billion people, and no one knows how many humans the earth can support. Our very existence and numbers are threatening many other species with extinction. We also have had some experience with terraforming our own planet: changing the landscape, the atmosphere and the climate. At present, we are aware of the importance of terraforming the earth as we try to control global warming, air and water pollution, and protect some natural habitats.

【5】While the future of such a project is daunting(令人生畏的), it is not impossible. Even if earth-bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from earth.

【6】The future existence of humanity may very well depend on our ability to terraform Mars.

Reseachers at the University of Kansas say that people can accurately judge 90 percent of a stranger's personality simply by looking at the person’s shoes.“Shoes convey useful information about their wearers,’’the authors wrote in the new study published in the Journal of Research in Personality.

Lead researcher Omri Gillath said the judgments were based on the style,cost,color and condition of someone’s shoes.In the study,63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study’s participants.Volunteers in the study were photographed in their most commonly worn shoes,and then filled out a personality questionnaire.

Some of the results were expected:People with higher incomes most commonly wore expensive shoes,and flashier shoes were typically worn by outgoing people.However,some of the more specific results are strange enough.For example,“practical and functional’’shoes were generally worn by more“pleasant"people,while ankle boots were more linked with ‘‘aggressive’’personalities.The strangest of all may be that those who wore‘‘uncomfortable looking” shoes tend to have “calm” personalities. And if you have several pairs of new shoes or take extreme care of them,you may suffer from“attachment anxiety",spending lots of time worrying about what other people think of your appearance.There was even a political calculation in the mix with more liberal(主张变革的)types wearing“shabbier and less expensive” shoes.

The researchers noted that some people will choose shoe styles to mask their actual personalities,but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities.

[1]Oops! In your rush to get to school, you drop a piece of toast on the floor. Do you throw it away or decide it’s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat, if you pick them up within 5 seconds of dropping them. But you might want to think again. Scientists now say that 5 seconds are all it takes for foods to become contaminated with enough bacteria to make you sick.

[2]Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If we eat foods on which these bacteria are growing, we can become sick. One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Earlier this year, 370 people became sick after eating peanut butter that had been contaminated with Salmonella at the manufacturing factory. Salmonella are often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods carefully.

[3]Being a good housekeeper is another good way to prevent infection. If household surfaces aren’t washed thoroughly, they can support Salmonella for weeks. A team of scientists at Clemson University in South Carolina have tested the 5-second rule, using sandwich ingredients. First, they placed a known amount of Salmonella cells on three surfaces: wood, tile, and carpet. They then placed a slice of bread and a slice of bologna(博洛尼亚大红肠) on each surface for 5, 30, or 60 seconds. After just 5 seconds, both the bread and bologna picked up enough bacteria to make you sick.

[4]So forget the 5-second rule. If your toast lands on the floor, throw it away. Stick a fresh slice of bread in the toaster. And this time, be careful not to drop it!
