2 . Landscaping (人造景观) refers to man-made features of a landscape such as driveways, walls, steps, and other human-made structures. It has many sustainability benefits.

Replace Lawns (草坪)

Fertilizers and pesticides (化肥和杀虫剂) help establish a beautiful lawn.     1     If you replace lawns with landscape, you’ll use fewer chemicals and do less harm to the environment.

Use Less Water

    2     So it can save hundreds of gallons of water and reduce the carbon emissions (排放) used to provide that water cleanly.

Use Locally-Produced Materials

Materials for landscaping are almost all produced locally, due to the high shipping cost.     3    

Lower Garden Maintenance (维护)

Usually, Americans spend two hours per day on lawn and garden care.     4     That often means less energy used to run some garden equipment.

Reduce Ice Build-up

Sustainable landscape allows stormwater to drain (流) into the soil.     5     This means safer walkways or driveways, and a reduced need for salt for de-icing (除去……上的冰).

A．Landscaping is a form of landscaping.

B．This means lower carbon emissions for transportation.

C．Yet little maintenance is needed for a landscaped area.

D．The water landscaping uses mainly comes from nature.

E．There are ways to lower your impact on the environment.

5 . Each dog is an individual and will have variances in their personality, meaning that there is no guarantee that the puppy you bring home will be a perfect fit. These are our best recommendations.

Australian Shepherd

Contrary to their name, the Australian Shepherd is actually an American kind. If you are planning to keep larger animals on your homestead, having a shepherd dog to help you control them is a must. Australian Shepherds are quick, light on their feet and highly intelligent.

This rapid intelligence also makes them excellent at trick training if you ever want to branch out and teach them to do other things.

American Labrador

Their love of the outdoors combined with their happy-go-lucky personalities makes them a great match for the homestead lifestyle, which makes them suitable for the elderly at home.

Though they have a love of chasing, Labradors make a great homestead dog as they have a very low chase drive. This means they are incredibly unlikely to chase and injure your animals.

Mastiff

Though they are not as intelligent as some of other kinds on this list, having a Mastiff on your homestead can act as a deterrent (威慑作用) for others. Providing a shelter for your mastiff-type dog to stay outside with your animals will cause any stealers to think twice before entering your property.

Great Pyrenees

Great Pyrenes have a very little desire to dig, so your vegetable patches are safe.

Equally, they have little desire to chase, and so your domestic animals are safe. Their naturally protective nature means they are happy to work as guard dogs, protecting all of them from stealers.

6 . I was very thrilled to go to camp the year I turned 11 — the first time I would venture so far from home. Leading up to the date, I convinced my mother I was ready to go for two whole weeks.

Finally, the day came. We reached the camp after a six-hour drive. After registering and meeting my counselor, I waved my mom away with confidence, eager to take the swim test and start having fun. Camp was more than I had imagined: crafts and games; singing and swimming; making bracelets (手镯) for new friends; listening to our counselor read to us before falling asleep to the sound of rain on a metal roof.

When the weekend arrived, there was a luncheon (午宴) for visiting parents and families. I met some of my camp mates’ relatives, then suck away with a sandwich. I went down to the dock to watch the water bugs skate across the surface of the lake. My counselor came and companionably beside me. She quietly asked me if I was okay. I told her it was too far for my family to visit.

I remember not looking at her or saying anything for what seemed like a long time. It felt like talking might change the magic of the place. But I also wanted her to know me just a little better, so I told her that my dad had died only a few weeks before whispering “cancer”, just like I had heard the adults say it.

She put her arm around my shoulder, and we sat for a while longer. It felt like she understood.

Summer camp gave me the opportunity to be an ordinary kid for a brief time that year — just a girl learning, laughing and having fun like everyone else.

9 . Prime Minister Justin Trudeau announced his plans for achieving net-zero emissions (排放) in Canada by 2050. His party subscribed a bill that would require the government to create new targets and a plan on how it will achieve those targets, every five years between 2030-2050. It would also have to regularly report on its progress towards those goals.

Canada is one of nearly 200 countries that has signed onto the Paris climate agreement. Signatories promise to achieve net-zero emissions beginning at some point between 2050 and 2100. Net-zero means that all emissions produced are absorbed through plants and trees or buried through carbon-capture technology.

Countries must also report on their progress every five years under the agreement. Mr. Trudeau’s bill, which was subscribed on Thursday, formalizes this reporting requirement and forces the government to set regular goals. Greenhouse gases have hit record lows because of the pandemic-induced (大流行病引起的) economic slowdown. US emissions dropped by 9.2% this year.

The bill does not provide any kind of enforcement mechanism (机制) or attach any additional spending to achieve its goals. The bill also does not detail how the country will meet its five-year targets. It simply says the government will be required to come up with a plan.

“Canada is a wonderful country, but it didn’t happen by accident and won’t continued without effort, ”Mr. Trudeau said. He made climate action a goal during his 2019 election cam paign.

Canada has failed to meet its environmental targets in the past. Under the Paris Agreement, Canada is supposed to reduce its emissions by 30%by 2030. The country will miss its 2020 target and is on track to miss its 2025 target.

1. What does “net-zero” mean in Paragraph 1?

A．Any emission is not allowed.	B．All emissions must be cleaned first.
C．All emissions must go though net.	D．All emissions are absorbed or buried.

2. What are countries also required to do under the Paris climate agreement?

A．Pass laws to cut emissions.	B．Report progress every five years.
C．Make targets every five years.	D．Find new ways, to reduce pollution.

3. Why have greenhouse gases hit record lows?

A．Countries all met their targets.	B．More advanced techniques were used.
C．Economy around the world slowed down.	D．People cared more about protecting the environment.

4. What can we learn about Canada from the last paragraph?

A．It will reduce its emissions by 30%.

B．It sets too high environmental targets.

C．It may not meet its environmental targets in the following years.

D．It doesn’t try to achieve its environmental targets.
