    You don’t have to break your back to create a yard that’s both beautiful and kind to Mother Nature. These environmentally smart ideas will turn your home turf (草地) into a small garden. 1.

Let the grass grow.

Cut grass less often, 2.. It will help grass survive dry periods of time in warmer months. That’s because roots will grow deeper and grass thicker, which means fewer pests, less disease, and a decreased need for chemical intervention.

3..

You can act before 10 a.m, when the air is cool. Watering in late afternoon is the next good choice. Water near the base of plants, slowly delivering the good stuff right to the roots. For lawns, water long and deep once a week.

Get keen on composting（肥料）.

Compost isn’t called gardener’s gold for nothing. It keeps kitchen leftover out of landfills and enriched soil with much-needed nutrients. 4.  Vegetables and tea bags, eggshells, dry leaves are all fair game.

Give bees the green-carpet treatment

Honeybees help pollinate（授粉）75 percent of the flowering plants and nearly 75 percent of food crops. Scientists say many important pollinators are disappearing. Creating a garden with plants which flower at different times of the year will benefit pollinators throughout the growing season.5..

A.Water the right way.

B.Many will save your money too.

C.Dry leaves add nutrients to the soil.

D.Make the backyard as beautiful as possible.

E.so it gets a few inches longer than you’re used to.

F.It also reduces dependency on chemical fertilizers.

G.Whenever possible, choose native plants with a variety of flower colors and shapes.

    The world’s elderly population is increasing. The number of older people ---those age 60 years or older ---is expected to double by 2050 and is growing faster than all younger age groups across the globe. That comes with an increasing need for caregivers which can provide 24-hour care, not only at hospitals or nursing homes, but also at private homes.

Already, caregiving robots are programmed to ask questions a nurse would ask and can keep an eye on patients for falls. These robotic assistants are expected to become increasingly marketable and reach 450,000 by 2045 because of the expected caregiver shortage in the USA.

“Unluckily, the hard structure of present caregiving robots prevents them from a safe human-robot interaction(互动), limiting their assistance to only social interaction and not physical interaction,” said Ramses Martinez, an assistant professor in Purdue’s College of Engineering . “After all, would you leave babies or old people in the hands of a robot?”

Recent advances in material science have enabled the production of soft robots with deformable (可变形的) bodies or the ability to reshape when touched , but today the complex design prevents the use of this technology at home .

However, Martinez and other researchers have developed a new design method which shows promise in enabling the production of soft robots using a 3D printer.

“The soft machines move like humans. Their ability to change their body structure and movement to adapt ( 适应 ) to a wide variety of environments will improve caregiving greatly,” says Martinez .

The researchers are looking for partners to test and bring their technology to market.
