For more than two decades, France is known as the world’s most popular tourist attraction, receiving 82 million foreign tourists every year. Here are some of the best places to visit in France.
Marseille
Marseille is one of Europe’s oldest cities and France’s second largest city. Having a nice climate, Roman ruins, medieval architecture and cultural scenes, Marseille is also a working city with several universities and industries. One of Marseille’s best natural attractions, the Calanques are a series of small rivers with astonishing blue water and splendid cliffs.
Luberon
During the summer months, many people like to experience charming villages in Luberon. This region in central Provence took off as a tourist attraction after Peter Mayle published his books about life in Provence. With its large quantities of forests, fields of lavender(薰衣草), farmers markets and colorfully painted houses, you'll soon see why the Luberon is such a tourist attraction.
Dordogne
There is just so much to see and do in Dordogne, beginning with picture-postcard villages and castles. The scenery is pretty amazing, too, with the Dordogne River running through it. The Dordogne also has some of the best ancient cave art in France. The walls of Lascaux feature mainly animals, which are a must-see.
Paris
Attracting more than 45 million visitors every year, Paris is the world's most popular tourist attraction. Paris, the capital city of France, is just like a little “France”.

【推荐2】Every day people board planes,get on trains and ready themselves for an adventure. But what about the deep sea? Although it covers 70 percent of the Earth's surface,we hardly stop to think of it as a tourist destination. However, the travel industry has made great advancement in creating aquatic(水中的) hotspots.
From the luxury to the relatively modest,underwater resorts have been popping up in recent years. For those with a truly adventurous spirit and some money to spend,you can even rent your own submarine. Staffed with a captain,a personal chef and a butler(管家),Oliver’s Travels’ submarine,the Lovers Deep,is a unique getaway. For those looking for a slightly different experience,there is Jules'Undersea Lodge in Florida,US,named after Jules Verne,the author of 20,000 Leagues Under the Sea.
Other sectors of the emerging underwater tourism industry have brought a bit of art to the deep sea. According to the BBC,“there's a move to combine underwater tourism with art tourism to attract a new kind of traveler." Underwater museums and exhibits like the Molinere Underwater Sculpture Park in Grenada and Australia's Museum of Underwater Art allow visitors to see incredible sculptures in a truly magnificent atmosphere. Underwater archaeological(考古的)sites have also become popular destinations, such as the ones in Turkey, where people can visit sunken cities.
Exploring Earth's bodies of water has brought more awareness to the importance of protecting oceans and the animal life that calls them home. British sculptor Jason deCaires Taylor,whose artwork can be seen in multiple underwater attractions around the world, feels this is key. “Most people just see the surface of the ocean and it is hard to think of something so plain and enormous as fragile. We don't regard our oceans as sacred(神圣的)and we should.”

【推荐3】As winter set in, it’s the perfect time to get out of town and escape the seasonal mood disorder. Here are vacation ideas to adopt now.
Costa Rica
Costa Rica, located in the Valle del General, is an off-the-radar agriculture town that’s not overrun with tourists. The area is known for its coffee, pineapples and sugar cane plantations, as well as its rich forests. What’s more, you can enjoy horseback riding, spend afternoons at the spa or tour a nearby wildlife shelter to look out for colorful birds, sloths and other animals.
Los Cabos, Mexico
If you love wine, travel to Los Cabos, a beautiful vacation destination at the southern edge of the Baja Peninsula. During your getaway, you can enjoy special wine tastings and dinner cooked by Los Cabos’s Michelin-starred chef. There are wildlife-viewing opportunities, too. From December through May, you can spot whales, manta rays and more wildlife.
Petit St Vincent, the Grenadines

Clear, 69°F
My wife, Eleanor, and I took the train from Paris to Strasbourg, where we were met by our driver and guide, and the minibus which goes along with the boat. We stopped off in Barn for an hour on the way. Then we were taken to Nancy where the boat was kept.
After the other passengers arrived, we had our first dinner on the boat. After dinner we walked into downtown Nancy, a village with a large square and wooden houses.
Monday, October 6
Rained last night, cloudy in the morning, 69°F
We spent about two hours in Nancy, then sailed on the Canal de la Marne au Rhine. Kind of a lazy day, eating breakfast, lunch, and dinner. After dinner we watched a tape on Baccarat, which we will visit tomorrow.
It was pleasant to sit out on deck and watch the scenery go by at about 3 mph.
Tuesday, October 7
Light rain, 64°F
This morning we drove over to Baccarat and toured its museum and the church, which has this unbelievable lamp that is going on a world tour the next day. We did lots of shopping, then walked across the bridge to see a very, very modern Catholic church with special Baccarat windows.
We drove to the top of the Voges Mountains and started down the eastern side. Later we drove to Sorrenbourg to see the 13th century church at the Cordeliers. It contains the largest window by Marc Chagall - 24 feet wide by 40 feet high.
Wednesday, October 8
Cloud, 65 °F
Today we sailed from Schneckenbush to Saverne. We went through two caves, an extremely unusual part of the journey. This river scenery is very different. We were in a mountain valley with grassland on one side and a forest beginning to show some color on the other.
Thursday, October 9
Cloudy, 66°F
Our dependable minibus was waiting to load the luggage and take us to the hotel where everyone went their separate ways. Our boating days are over until next time.

【推荐3】One of the newest “smart” devices is an old favorite, a camera. And smart cameras are getting smarter all the time. Some are now built with machine learning tools to help them think for themselves. Machine learning involves putting large amounts of data into a computer for processing.
Google Clips
One of the latest to launch is Google Clips. It is the first camera developed by the web search giant that is not built into a phone.
The small and light device is designed to be put somewhere in a room to take pictures by itself. It can also be stuck to an object or a person’s clothing.
Google says machine learning helps the camera choose the best times and situations for taking pictures and video clips. It can also recognize the faces of people or pets chosen by the user and take pictures of them in a more natural way.
The device is not yet being sold, but interested buyers can join a waiting list to be informed when it is available.
GoPro Hero
GoPro is another company developing machine learning technology. GoPro also uses machine learning to power its QuikStories feature. This tool takes existing photos and videos and automatically creates a finished video piece, complete with music and effects.
Snap Spectacles
Messaging app Snapchat sells a pair of sunglasses with a built-in camera that can record short video clips with the push of a button. Snap Inc. says the product, called Spectacles, is designed to “capture the moment, without taking you out of it”. Many smart phones already have facial recognition technology built into the devices.
Snap Inc. has started selling its Spectacles sunglasses online in the United States.
Apple iPhone X
Apple’s new iPhone X is being launched with its new Face ID system that it says will unlock the phone just by having the user look at it. This replaces the Touch ID on previous devices that used a fingerprint to unlock the phone.
Apple says the system works by projecting more than 30, 000 dots on the face to create a kind of map. Apple claims its facial recognition is even secure enough to allow payments through its Apple Pay service.

【推荐2】What do you use your fridge for: It can not only keep your food cold, but also make ice and freeze food. But in the future smart fridges may do much more than you can think. They may tell you what food is inside, what food you need, what food is healthy for you, and even shop for you, too!
Some companies are making online fridges which have a computer screen on the door. And it can be very useful that the computer is linked to a supermarket through the Internet. For example, when you finish your orange juice, you can put the empty juice carton (纸盒包装) near the computer screen. The computer reads the bar code on the juice carton. Then it orders more orange juice from the supermarket. You can also use the computer screen to order other things from the supermarket. The computer screen has a series of things that are in the store. You can choose what you need. The supermarket will send the food to your home.
Companies are making other kinds of “smart” appliances (电器), too. There is a new kind of microwave oven (微波炉) which has a computer memory. It can remember 365 different cookbooks. There is also a smart mixer that can remember cookbooks. Even it can test ingredients for you!
Of course, sometimes these smart appliances don’t work. When they do, they will tell you. And then they can call someone to fix them, too!

Society tends to think of high school dropouts as kids who just can’t cut it. They are lazy, and perhaps not too bright. So researchers were surprised when they asked more than 450 kids who quit school about why they left.
“The vast majority actually had passing grades and they were confident that they could have graduated from high school.” John Bridgeland, the executive researcher said. About one million teens leave school each year. Only about half of African-American and Hispanic(美籍西班牙的)students will receive a diploma(证书), and actually all dropouts come to regret their decision. So, if failing grades don’t explain why these kids quit, what does? Again, John Bridgeland: “The most dependable finding was that they were bored.” “They found classes uninteresting; they weren’t inspired or motivated. They didn’t see any direct connection between what they were learning in the classroom to their own lives, or to their career aspirations.”
The study found that most teens who do drop out wait until they turn sixteen, which happens to be the age at which most states allow students to quit. In the U.S., only one state, New Mexico, has a law requiring teenagers to stay in high school until they graduate. Only four states: California, Tennessee, Texas and Utah, plus the District of Columbia, require school attendance until age 18, no exceptions. Jeffrey Grin, another researcher, says raising the compulsory attendance age may be one way to keep more kids in school.
“As these dropouts look back, they realize they’ve made a mistake. And anything that sort of gives these people an extra push to stick it out and see it through to the end, is probably helpful measure.”
New Hampshire may be the next state to raise its school attendance age to 18. But critics say that forcing the students unwilling to continue their studies to stay in school misses the point—the need for reform. It’s been called for to reinvent high school education to make it more challenging and relevant, and to ensure that kids who do stick it out receive a diploma that actually means something.
1. According to researchers’ study, most high school students drop out of school because____________.

【推荐2】A young kangaroo is lucky to be alive today thanks to a pair of New South Wales teenagers.
Nick Heath and Jack Donnelly, both 19, were riding their motorbikes in the bush outside Sydney on Sunday when they came across a kangaroo stuck in the mud.
The boys saw the head of the animal sticking out of the mud at Agnes Banks near the Nepean River in southwest Sydney. The animal was clearly in pain but the boys couldn’t reach it, so they raced home to get some rope. When they returned, Mr. Donnelly tied the rope around his waist and walked into the thick mud to get hold of the kangaroo while his friend then pulled them about 30 meters to safety.
Appearing on Today this morning, the young men retold their experience to save the animal.
“The kanguarwo’s life was important to us sowe pulled out all the stops to rescue it,” Mr. Heath said. “We lake pride in what we did. If we see something like that again, we’ll do it all over again,” Mr Heath added.
The animal, while not in great health after being save, was handed to wildlife rescue organization WIRES. It’s believed that the kangaroo was likely searching for water in the dry conditions when it got stuck in the mud.
As for the heroes of the story, they re glad to have been in the right place at the right time to help the animal—and don’t mind the attention it’s brought.
“Yeah we liked it, something different,” Mr. Donnelly told news.com.au.

【推荐3】Plane wings are traditionally strong and thick but a team of researchers led by NASA has created a flexible wing that morphs (变形) as it flies. The new wing is constructed from thousands of units that fit together and function in a similar way to a bird’s wing, says NASA research engineer, Nick Cramer.
“Something like an eagle will lock its joints in while it’s cruising, and then it adjusts its wings to a more suitable shape for its cruising, and then when it wants to do a more aggressive move it’ll unlock its shoulder. That’s a similar response to what we’re doing here,” he said.
The Boeing 787 Dreamliner is constructed from body parts that are so large, so they require outsize molds (模具) to create them. The same applies to the Airbus A380. “The cost of infrastructure (基础设施) that the business needs to invest to build these planes is pretty extraordinary,” said Kenneth Cheung, a NASA research scientist. “So what we’re doing with these projects is trying to reduce all of that, so that you could have the same sort of performance in terms of the materials but be able to manufacture it without setting up all of the infrastructure that’s currently required.”
The new wings are created by putting fiber reinforced polyetherimide into a 3D mold to create each part, which locks together in a process that could eventually be carried out by assembly robots. The new structure can also be easily packed down to allow transport, which also makes it potentially the ideal package for another purpose — to send into space.
While the idea of cheaper, more flexible planes could be appealing to the commercial aviation industry, there are major obstacles to overcome. That demands time, research and money. “If you want to revolutionize the traditional manufacturing process of the aerospace industry, you have to have a really good reason,” Cramer said. “So your performance gain has to be significant enough to justify that. It’s not about whether it’s practicable; it’s about whether it’s financially marketable.”
