New research into a long-lived tree has shown some of the tricks that have helped it survive for thousands of years. The ginkgo(银杏树) is a huge, slow-growing tree with fan-shaped leaves, native to China, but planted in parks and gardens across the world. Some of the largest ginkgoes are said to be more than 3, 000 years old.

In order to discover how these and other trees can live for so long, scientists from the US and China studied 34 healthy ginkgoes of different ages. The team studied growth rings in each tree's trunk(树干), as well as cells(细胞) from the bark, leaves and seeds. They found that 600-year-old trees were just as healthy as 2-year-olds.

To learn more, the team then looked in detail at the DNA of nine trees aged between three and 667 years old. DNA is the chemical in the cells of plants and animals that holds instructions that tell any living thing how to grow and develop-including what to do at different times in its life At the beginning of a tree's life, DNA instructs the cells in a seedling to divide quickly so the tree grows rapidly. The cells also make special chemicals to help the young plant survive difficult situations, such as disease. As most trees grow older, their DNA tells their cells to divide more slowly (so growth slows down) and to make fewer chemical defenses(防御).

Ginkgoes, however, do things differently. The team found that although their growth finally slows, both young and old trees make protective chemicals." The secret is keeping a really healthy defense system," said researcher Richard Dixon." As ginkgoes age, they show no sign of weakening their ability to defend themselves from things like disease. "Other trees that live for a long time may have the same ability.

For all their defenses, though, ginkgoes cannot live forever--they finally meet with deadly accidents such as fire, disease and storms. While they last, however, these leafy trees are some of the most beautiful trees in the world.

(1)、What do we know about ginkgoes?
A、They first grew in China. B、The oldest ones are 3,000 years old. C、They are little known to the public. D、They are the oldest plants.
(2)、How did the researchers carry out their study?

Urban Transportation in Canada

    Public transportation Transit passes

    All cities and most major towns in Canada have a public transportation system with one or more modes of transportation(bus, subway, train, etc. ) The bus is the most common form of urban transportation in Canada. To use public transportation, you must purchase a ticket or a transit pass. Transit passes allow you unlimited use of public transportation for a specific period (one month or more). They are usually cheaper than buying many tickets if you plan to use public transportation often.

    Transportation for people with disabilities

    Public transportation often has features to assist people with disabilities. In many cities and towns, there are also transportation services available specifically for people with limited mobility, such as specially equipped buses. You can find out about these services in the same way you would learn more about other public transportation options.

    Etiquette on public transportation

    When taking public transportation such as a bus or train, it is important to understand the unspoken rules of conduct in the shared space. Here are a few things to note:

    Be polite and respectful to others around you. For example, maintain an appropriate noise level when talking or making a phone call.

If you are carrying a backpack or a large shoulder bag in a crowded public transit vehicle, keep it close to you, preferably at your feet to avoid hitting people with it as you walk by.

    Avoid pushing or touching others in order to make more room for yourself. Sometimes public transit can become very crowded, but it is important to keep calm and give others appropriate personal space.

    Have your proof of payment accessible in case you are asked to show it.

    A walk through the galleries of Quebec's Montreal Museum of Fine Arts (MMFA) places individuals face-to-face with some 43,000 artworks ranging from Chinese ceramics(陶瓷制品) to Inuit sculpture.

    While the visiting is an incredible cultural experience, a group of local physicians will soon be able to prescribe(开处方) museum visits as treatment for some illnesses.

"We know that art contributes to neural(神经的) activity," said MMFA director Nathalie Bondil. "What we see is that being in contact with art can really help your well-being."

Hélène Boyer, vice president of a Montreal-based medical association, explains that museum visits have been shown to increase levels of serotonin, a neurotransmitter(神经传导物质) known as the "happy chemical" which helps to lift mood.

    According to Boyer, the small increase in hormones(荷尔蒙)associated with enjoying an afternoon of art is similar to that offered by exercise, making museum prescriptions ideal for the elderly experiencing pain that prevents them from regularly joining in physical activity.

    The museum visits are designed to improve traditional methods. As Bondil notes, spending time in a peaceful environment can provide a welcome distraction. "What is most important is this experience can help them escape from their own pain," she says. "When you enter the museum, you escape from the speed of our daily life."

    "I am convinced that in the 21st century, culture will be what physical activity was for health in the 20th century," said Bondil. "Some people would do well to recall that just in the 19th century, sports were believed to do harm to the body. Just as doctors now prescribe exercise, they will be able to prescribe a visit to the MMFA."

    Nola (August 21, 1974 -November 22, 2015) was a northern white rhino(犀牛)who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day, held on September 22, is to raise awareness of the less than 30,000 other rhinos left on Earth.

    "Rhinos need our help today, not tomorrow," Nola's lead keeper Jane Kennedy said. "Last year we lost over 1,200 rhinos just in South Africa. If we continue to lose more than 1,000 rhinos a year, in 10 to 20 years all the rhinos on the planet will be gone."

    "Unfortunately, most animals are in danger of dying out because of humans," Kennedy says." Humans have either poached(偷猎)animals, or because there are over seven billion of us, we've taken up too much of the world's resources ". Poachers illegally hunt rhinos for their horns. They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations. Experts believe that one rhino is poached every eight hours.

    In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell (细胞) samples from more than 8,000 different types of animals, including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.

    Jane Kennedy describes World Rhino Day as "a celebration of rhinos along with an awareness campaign for everybody across the world to know that rhinos need our help." At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. But you don't have to live in San Diego to celebrate World Rhino Day. It is observed around the world, with zoos and wildlife parks holding special events and programs to teach people about rhinos, and enable them to see the animals up close.

The brain-training app trains people to tap on images of healthy foods but to stop when they see unhealthy snacks, creating a link between these foods and stops. The new study, by the universities of Exeter and Helsinki, found that playing the game about once a day for a month led to an average one-point reduction of junk food consumption.

Generally, people who used the app more also reported great changes in their food intake. One app user wrote, "Really useful. I used to eat junk food two to four times a week and I have reduced this to once a week after using the app regularly for a month. My desire for junk food has been reduced greatly and I no longer eat in the evening mindlessly."

The study used the app's usage data, and the app regularly asked questions about how often users eat certain food, along with other information such as their age and weight. The findings suggested that using the app regularly was linked with big changes in eating habits.

The app is free and it only takes about four minutes per day, so it's something people can do not just at home but at work and elsewhere. "From our results it seems important that you do the training at regular times and don't just stop. Therefore, keep it interesting, so you won't get bored with it. Personalize the app as much as possible and pick the food that you find really hard to resist," said Natalia Lawrence, a professor of the University of Exeter.

The researchers stressed that their findings should be further proved, because there was no comparison group and other factors____(such as the possibility that people who did more training were also more motivated to lose weight) could play a part in the results.
