Can trees talk? Yes, but not in words. Scientists have reason to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special smell — a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty.

Communication, of course, doesn't need to be in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar for honey. So why shouldn't trees have ways of sending message?

What will restaurants look like in the future? What would your dinner taste like if a robot cooked it? A robot restaurant in Tianjin may give you the answers. Covering an area of over 400 square meters with a total of 112 seats, the X Future Restaurant is a robot restaurant opened in November 2018. The restaurant has amazed customers with its fully automated(全自动的) technology, which covers every step of the dining experience, from ordering to cooking to serving the dishes and even taking payment.

Entering the restaurant, one can order dishes by simply scanning(扫描)the QR codes on the table. There are over 40 choices of dishes. After taking the order, “robot cooks” prepare dishes using fixed time, temperature and ingredients designed by famous Chinese cooks.

“As the cooking is controlled by a computer system, the taste and quality of dishes can be good,” said Li Xiaokui, manager of the X Future Restaurant.

Robots also complete the delivery of dishes. Without following any designed route, the robot waiters serve meals thanks to automated driving technology, which helps each robot timely change its route when something is in the way.

These eye-catching technologies have received wide praise from customers. “The dishes taste surprisingly good. I couldn't believe that they were made by robots, especially dishes that were difficult to cook.” one customer said. “The application of robots has increased our efficiency(效率)and cut down our costs,” Li said, “I think robot restaurants will develop fast and have a bright future.”

Sundays in New York can be very pleasant. That's not to say that Sundays in other American cities are not pleasant, but New Yorkers feel that their Sundays are special.

Since Saturday nights are traditionally party nights, Sunday morning are traditionally morning of rest, which means having a long sleep. We call it sleeping in or sleeping late, and staying in bed until 9, 10 or even 11 o'clock is not unusual. Then jump out of bed, hastily pull on clothes, run to the nearest corner newsstand, buy the New York Times or Daily News(or both), return home, put some classical music or popular singer on the record player, take off   your clothes and climb right back into bed to leisurely read the paper.

One of the nicest traditions is breakfast in bed. The Times and News are very fat newspapers on Sundays so there is a lot to read while one drinks orange juice and coffee, lying in bed.

If the weather is bad you might immediately turn to the Entertainment Section of the paper to see what movies are on. Sunday afternoons are a popular time for seeing a film, but movies are expensive in New York (as much as $5.00) so choosing takes time and care. Read the movie reviews to discover what the critics think. No one wants to make an expensive mistake…nor does anyone want to stand in line a long time which is very possible if the movie is new and gets good reviews. So if you're not sure about a movie look at the museum listings to see what exhibitions are in town. Some museums are free, others are not.

But if the weather is good you might glance through the section which lists outdoor activities. Almost every Sunday in the springtime residential neighborhoods request permission from the Police Department to close off streets for “street fairs”. There will be food for sale made by local residents or restaurants; handicrafts for sale; music provided by a local band (often high school kids); and perhaps dancing. If the fair is in Little Italy you can expect to find tasty Italian food. If the fair is in China-town you can expect to find egg rolls, music played on the erhu and dragon dances.
