1 . Have you ever made a mistake while trying to print from a computer? That paper probably went right into the recycling bin. From there, it is taken to a waste-handling plant to be eventually broken down and remade. But what if you could simply erase your mistake and reuse that paper? It may become available, thanks to a new technology.
It's a new type of rewritable paper that can be used more than 100 times. Words and pictures remain visible on it for at least half a year. This is nearly the first rewritable paper. But the marks on those earlier versions tended to fade away in less than three months.
Luzhuo Chen led the group that made the new rewritable paper. His team was inspired by pens that contain erasable ink. That ink disappears when heated. To make its new rewritable paper, Chen's group switched the ink from the pen to the paper. They covered one side of regular paper with the ink used in those erasable pens. Using a heated pen or printer, they can now write or print on this paper. That warmth makes the ink disappear.
This is the opposite of how writing usually works, where ink is applied to paper. With the new system, the spots where you write become white instead of colored because that heat makes the ink covering the white paper disappear.
Qiang Zhao has a creative mind behind another type of rewritable paper. He thinks Chen's paper is simple and doesn't cost much to make, so it should be easy and fairly inexpensive to produce. However, the paper will need a lot of ink. In large doses（剂量），chemicals in the ink can be bad for the environment and people's health. Zhao would like scientists to develop a safer ink. Still, he thinks this paper will have wide applications.

2 . Los Angeles is always a popular holiday destination. To fully enjoy your travel there, you should know its food, weather, and also traffic. While driving in L. A. is similar to that in other areas, there are a few specific rules to note.
HOV lanes (车道)
On many L. A. freeways, one or more lanes at the far left are used as high-occupancy vehicle (HOV) lanes. They usually have limited access and you can only enter or exit where there is a break in the double yellow line. Most HOV lanes require a minimum of two people in the car; some require three. Vehicles towing trailers (拖车) are NOT allowed in the HOV lane, regardless of how many people are in them.
Toll (收费) lanes
On certain freeways, the HOV lanes are double-purposed as toll lanes for people driving alone who have a FasTrak, an electronic toll collection system. Therefore, you also have to have one in that lane as a HOV, which is inconvenient if you’re just visiting. FasTrak is in effect on parts of the 110 freeway between the 405 and 10 freeways, and on parts of the 10 freeway east of Downtown L. A.
Cell phones
It is against the law to talk on a cell phone while driving without using a hands-free device. Holding a cell phone to your ear while driving will land you with a ticket.
Alcohol
Driving under the influence is taken seriously in L.A. The legal blood alcohol limit is 0.08%, but you can be charged with lower levels if they show you can’t function normally. Placing an opened bottle of alcohol in the passenger area while driving (or sitting) is illegal. Any opened container of alcohol has to be transported in the trunk.
1. What do you know about HOV lanes?| A．They encourage people to share cars. |
| B．They are on the far right of freeways. |
| C．They are intended for larger vehicles. |
| D．They allow cars to enter over the double yellow line. |
| A．Driving on the 110 freeway with a FasTrak. |
| B．Putting the cell phone in the car while driving. |
| C．Riding with an opened bottle of alcohol in back seats. |
| D．Going below the blood alcohol limit of 0. 08%. |
| A．A traffic law. | B．A road map. |
| C．A guidebook. | D．A report. |
3 . Thailand's southern beaches attract travelers with their clean water and dramatic cliffs (峭壁), but there's more to explore in this Southeast Asian country.
Lopburi for history buffs
Bypass the tour groups at the ancient city of Ayutthaya and head two hours north of the capital, Bangkok, for a peaceful walk through Thai history. Lopburi, one of Thailand's oldest cities, boasts Khmer-era temples and the uncrowded ruins of King Narai's Palace, which was built in the 1600s. It's also known for the monkeys that gather at Phra Prang Sam Yot temple in the center of town.
Ban Krut for beach bums
In Ban Krut, travelers will find one of the cleanest and quietest stretches of white sandy beach within driving distance of Bangkok. This sleepy seaside community, known mostly by locals, is a five-hour drive or six-hour train trip down the Gulf of Thailand. Don't miss the magnificent Wat Tang Sai, a huge, fairy tale castle-like Buddhist temple.
Cave for holiday hikers
Hiking trails, wetlands and forests make Khao Sam Roi Yot National Park a weekend adventure worthy of topping your Thailand to-do list. The park's crown jewel is the extraordinary Phraya Nakhon Cave. Come early to catch the picturesque chamber flooded with morning sunshine that spotlights the royal pavilion that sits inside.
River Kwai for nature lovers
Most visitors come for the beaches, but the rivers and parks in Thailand's Kanchanaburi province have much to offer. Scenic trails and waterfalls abound in Sai Yok and Erawan national parks. Just two hours from Bangkok is the bridge made famous in the book Bridge over the River Kwai by French author, Pierre Boulle, and the 1957 Academy Award-winning 1957 film adaptation of the same name. Stay on the river at one of Kanchanaburi's many floating hotels, where you can travel to your front door.

About a year ago，NASA offered $125 ,000 to Anjan Contractor， a 3-D technology expert，to build a device（设备）that would allow astronauts to make pizza on demand． The mechanical engineer promised that his invention would produce pies in large quantities that looked， tasted and even smelled like pizza made in common ovens．
Late last year， the engineer presented a video of his first prototype（原型）that begins by creating a single slice of dough（面团）that is cooked and printed at the same time．Then comes the tomato “sauce” — a mix of tomato powder，oil and water and finally，a protein slice that resembles cheese．While the video doesn’t show the baking process，the inventor says that once the pizza is printed，it can be ready to be consumed in 7 seconds．
While the pie in the video looks delicious enough to attract any pizza lover，Anjan Contractor is far from ready for astronauts．That’s because he still has to find a solution to make the food container in the printer last for 30 years．Though that may sound unrealistic，actually it is not．
Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients（配料）and then they are reduced to the powder form．This，as you can imagine，will not be so easy．But，while the printer may not be ready for space，it certainly looks ready enough for people on earth．Hopefully，NASA and Contractor will consider selling it to those not fortunate enough to go to Mars！
