Have you ever wished you could grow fresh fruit in your garden but worry about there not being enough space, or it won't look pretty, or it's too difficult?

    What if I was to tell you that even a beginner can successfully grow a wide variety of fruit from apples and pears to cherries, blueberries and raspberries, and possibly even figs or nectarines?

    The first thing you need to know: the sweeter the fruit, the more sun it will require. If you have a sunny wall it's an ideal place to train a sun-loving fruit tree like a peach or an apricot. Plant the tree at the base of the wall but not too close (about 30cm is about right) in soil enriched with fertilizer (肥料). As it grows, splay (整枝) the branches evenly and attach them to the wall. As the plant grows gradually cut out old untidy branches and tie in new healthy branches. The idea of splaying or “fanning” is that as much sun as possible gets to the fruit, so it can ripen beautifully and maximize your crop.

    Choose a variety that won't grow too large. In slightly shadier spots you can grow gooseberries or raspberries. Most of these come in compact (紧凑的) varieties and can also be fan-trained against a wall if space is an issue.

    I have a tiny orchard (果园) of space-saving apple, pear and plum trees bought as single vertical stems (茎) which I grow in pots. They grow to a maximum of 2m high and no wider than 45cm. My children love them! Simply cut back the side stems to about 10cm at this time of year and you're good to go. Just remember that pot-grown plants rely totally on you for their food and water.

    As a gardener I was quite late to fruit-growing, but I realized quickly that it becomes an addictive hobby. And as a complete bonus I've noticed a definite increase in my bee population over the past few years. There's free food, and it's good for the environment too. What could be better?

    On December 26, 2004, hundreds of tourists relaxed on Sri Lanka's Yala National Park's beaches. But at mid-morning the park's elephants began crying wildly and running away from the ocean and up a nearby hill. The puzzled keepers could tell the animals were worried about something but what?

    What the keepers did not know was that a 30-foot wall of water was headed straight toward them. This tsunami(海啸) had been caused by an earthquake more than 1, 000 miles away in the Indian Ocean. When the huge wave hit the coast, it caused severe damage. Many people died. The elephants, however, were not swept away by the water. They stood safely on the hill.

    Scientists have long suspected that animals sense natural disasters before humans do. People have told stories of dogs refusing to go outside and sharks swimming to deeper waters before a hurricane. After the 2004 tsunami, people said they saw tigers, monkeys, and water buffalo escaping to higher ground before the waters rushed in. Even in the hardest-hit areas of southern Asia, there were few animal deaths.

    It's unlikely that an animal's so-called sixth sense comes from some magical power to see into the future. Experts believe that animals may be more sensitive than humans to changes in temperature and other environmental conditions that take place before a natural disaster. The elephants in Sri Lanka, for example, may have picked up vibrations from within the Earth, a sign that earthquake was coming. Because vibrations in the ground travel much faster than an ocean wave, the elephants may have felt the earthquake that caused the tsunami well before the tsunami itself came to the coast.

    A few scientists are calling for a system to track reports of strange behavior in people's pets, hoping that these reports can serve as a warning system that a natural disaster is about to happen. But Marina Haynes, an animal behavior scientist at the Philadelphia Zoo, says, "It would be an unreliable way to predict disasters. It can be difficult to know what an animal is doing. Is the animal nervous because an earthquake is about to happen or is it frightened because there is an enemy nearby?"

How to Bring Our Community Together

Canada is a nation that prides itself on multiculturalism and the opportunity. {#blank#}1{#/blank#} Building social connections and a sense of belonging brings people together in ways that strengthen individual relationships as well as the whole community.

There are several things that we can do to develop strong social connections and a sense of belonging :

{#blank#}2{#/blank#} One of the simplest ways to bring a community together is through shared experiences. Events like an international food festival, a sports league featuring activities from around the world, and health and wellness programs drawing on different cultures, are excellent ways of bringing people together.

Think outside the box. {#blank#}3{#/blank#} Many of us get caught up in our own routines and practices and forget that there are other ways of doing things. Try talking to different community members, ranging from youths to seniors, to understand their opinions of the world. {#blank#}4{#/blank#} .

Try new things. Positively influencing our community can go beyond volunteering our time and resources.

Consider getting involved in our community by working for the 2017 Census(人口普查)as an enumerator (普查员) or a crew leader. Census enumerators are responsible for identifying dwellings on maps, conducting personal interviews, and following up respondents in person and by phone, while crew leaders are responsible for leading, training and supervising a team of enumerators. {#blank#}5{#/blank#}.

A strong feeling of unity in a community can make residents feel comfortable and at home.
 

A. Plan community events.

B. Encourage community members to do some community service work.

C. Social connections offer community members chances to know each other better.

D. Our multicultural tradition provides a welcoming environment for individuals and families.

E. Learning about different cultures and practices can open our mind to a whole new way of life.

F. Invite individuals of different cultures to participate in community planning to ensure that every voice is heard.

G. These positions provide an opportunity to meet new people and build relationships with members of our

community.

Bright and early on the morning of our first full day in Antarctica, L' Austral's Captain Fabien's voice woke us up as it came through a loudspeaker. If we looked outside right now, he said, we'd see a beautiful sea of icebergs in the golden sunlight. My sister and I jumped out of bed, staring in amazement as we sailed past giant pieces of ice. In the distance, we spotted a group of humpback whales feeding on smaller fishes. Next door, my parents were also waking up to the sights of a new day in Antarctica. Over breakfast, my sister and I excitedly told them about the whales we saw from our room that morning.

You might not immediately think of "family vacation" when talking about a trip to Antarctica, but tour companies like Adventures by Disney are changing that. The company offers guided group trips to destinations across all seven continents in the world.

Our adventure started when we flew to Buenos Aires and explored the beautiful Argentine capital for a day. After leaving Buenos Aires, we flew to Ushuaia on an Adventures by Disney plane. Then, it was the journey toward the Drake Passage. After a speedy Drake Passage crossing, we reached Antarctica early, adding a half day to our scheduled four days on and around the continent.

To those unfamiliar with Adventures by Disney, the fact that you can experience Antarctica-the most distant, extreme continent-with Disney might be surprising. During the trip, there were thoughtful acts, from stamped postcards to send from an Antarctica post office to a champagne (香槟) party on our final stop of the journey; Adventures by Disney truly thought of everything for us. Antarctica is a life-changing destination packed with experiences that can't be copied. We experienced seasickness when travelling across the Drake Passage, hiked up ice hills alongside lovely animals, and had a taste of champagne. And honestly, it's going to be hard for the next family trip we may take to compete.

Robots have long been drawing inspiration from animals, with the creation of robot dogs or snake-shaped robots. And yet, the field of robotics is far less enthusiastic about the other kind of living things—plants. Barbara Mazzolai, an Italian roboticist owes this to a misconception about plant behavior: that they cannot move or think. "It's not true at all, " she says. To challenge this view, Dr Mazzolai and her team recently launched a machine called "FiloBot", a robot based on a climbing species. 

To survive, a climbing plant must switch between several different behaviors. In forest environments, it must first grow out of the soil and travel along the ground in search of a support to hold onto, such as a nearby tree. Once a support is located, though, the plant fixes itself around the object and then growing towards the light. To choose the best angle to grow upwards, a climbing plant uses its shoots(芽) to receive information about light and gravity. 

FiloBot has sensors on its main shoot. It can 3D-print its body with plastic and grow at a controllable rate. These functions, researchers found, enabled FiloBot to cross gaps, and find things to attach to. The lack of heavy on-board computing device means that it is light and requires minimal care, while its slow pace means that it doesn't disturb things around it, making it possible to move through a complex, unseen environment, or monitoring disaster sites. 

For now, FiloBot is still being tested. Its tendrils(卷须) have not left the laboratory. Still, it has already been employed in deconstructing plant behaviour. For example, it was long assumed that climbing plants find their supports by growing towards shade, though the exact mechanism was unclear. FiloBot could imitate this behaviour by detecting far-red light, which is typical of shaded areas, providing clues to how plants do it. 

Dr Mazzolai hopes that such projects will inspire other roboticists to take their cues from plants and develop completely new technologies.
