    Can trees talk? Yes—but not in words. Scientists have reasons to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree (柳树) attacked in the woods by caterpillars (毛毛虫) changed the chemistry of its leaves and made them tasteless so that the caterpillars got tired of the leaves and stopped eating them. And the tree sent out a special vapor—a signal causing its neighbors to change the chemistry of their own leaves and make themselves taste also terrible too.

    Talking, of course, doesn't need to be always in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds 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 (花蜜) for honey. So why shouldn't trees have ways of sending messages?

(1)、From the passage, which kind of leaves don't caterpillars eat?
A、Leaves lying on the ground. B、Leaves having an unpleasant taste. C、Leaves bees don't like. D、Leaves having an unfamiliar shape.
(2)、The willow tree described in the passage protected itself by __________.
A、growing more branches B、talking with birds and bees C、changing the chemistry of its leaves D、shaking caterpillars off
(3)、According to the passage, the willow tree was able to talk with other trees by __________.
A、waving its branches B、giving off a special vapor C、dropping its leaves D、changing the colour of its trunk
(4)、According to the passage, bees talk by __________.
A、making special movements B、touching one another C、smelling one another D、making unusual sounds
(5)、What does the author think about the idea that trees can talk?
A、It is not true at all. B、Only a few people believe it. C、The scientists made some mistakes. D、It seems very reasonable.

David Gill might be the richest man in Sebastopol, California. The semi-retired health care officer is banking the most valuable currency (货币) in the world—TIME. Gill has 480 hours saved at the local time bank.

In brief, a time bank does with time what other banks do with money: It stores and trades it. "Time banking means that for every hour you give to your community, you receive an hour credit (积分)," explains Krista Wyatt, a director of the nonprofit TimeBanks. Org, which helps volunteers set up local time banks all over the world.

Nobody knows the exact number, but thousands of time banks with several hundred thousand members have been set up in at least 37 countries, including China, Malaysia, Japan, Senegal, Argentina, Brazil and in Europe, with over 3.2 million exchanges. There are probably more than 40,000 members in over 500 time banks in the US.

In Sebastopol, 250 local people have time bank accounts (账户) where they save and withdraw hours as needed. For example, Gill likes to offer his advice and help with computer programming, editing and financial (经济的) planning. In return, he asks for help when he needs a ride to the airport or someone to transport heavy furniture. The time banks are building social capital (资本). "I've made wonderful friends I wouldn't have met otherwise and we now invite each other to our garden parties," says Gill. "It's about making community and being a part of the community. You can't put a price on that."

David Gill came to the time bank like most of his neighbors. He doesn't remember where he first heard about it a few years ago, but he immediately thought it was a great idea. He signed up, started using it, and when the founders asked for help, he stepped up. He gets paid in the currency he values most: hours.

Time banks are a valuable resource for building social capital and supporting aging populations. They allow people to contribute to their community and receive help in return, creating a stronger, more connected society.

We've all been there. It has been a long day, there is nothing in the fridge, cooking seems arduous and the solution is obvious: takeaway. It's easy for takeaways to become a regular habit. At some point, you have to wonder: even if you don't look different in the mirror, is it doing you any harm?

There is some evidence that too many takeaways is related to weight gain, but the relationship isn't clear. A 2022 study found a connection between eating takeaway-style food in the 24 hours before taking the survey and increased BMI in participants, although the researchers were careful to point out that they didn't know whether frequently eating takeaways made people overweight, or whether overweight people frequently eat takeaways. There is, however, evidence that simply living near(or walking past) a takeaway outlets(外卖店) or two can affect body weight, and reaching out to takeaway outlets near your workplace is most likely to attract people.

But why? Well, takeaway food are usually high in fat and salt - ingredients(成分) that are relatively cheap and taste good, making you more likely to reorder. There is also some evidence that junk food can be addictive(上瘾的), as the combination of salt, fat and sugar makes it hard to stop eating.

There is also the nutritional quality of the ingredients themselves. "Most takeaways contain highly processed ingredients and additives, nutrient-poor carbohydrates(碳水化合物) and plenty of deep-fried foods cooked in oil repeatedly heated to high temperatures," says Pearson.

So, what is the message? If you must place that order, consider the options:

The worst foods on any menu are likely to be fried ones, or anything covered in high-sugar sauces. If you order Chinese food, go for steamed dumplings, grilled fish or soup. If you are going for Indian food, go heavy on the side dishes, like bean and potato curries, which are often more flavourful and healthy.

Finally, try to cut your consumption(消费): consider changing your daily routes, hide the menus, and delete the apps on your phone.
