Many people can't imagine life without dogs. 1.. However, dogs and people are very different animals. To make the most of your relationship with your dog, you need to teach her some important skills. Here are three essential principles to keep in mind while teaching.
2..
One of the most frequent complaints of pet parents is that their dogs "just won't listen". But put yourself in your dog's shoes for a moment. If someone was constantly speaking in a foreign language how long would you pay attention? Probably not for very long because you simply couldn't understand what the foreign speaker was trying to communicate. Thus, you need to understand how.
If you like the behavior, reward it.
Some training methods use punishment, like scolding, to discourage dogs from doing everything except what you want them to do. 3.. While both strategies can work, the latter is usually the more effective approach, and it's also much more enjoyable for you and your dog.
Control consequences effectively
As you teach your dog dos and don'ts, bear the following two guideline in mind;
Consequences must be immediate. Dogs live in the present. Unlike us, they can't make connections between events and experiences that are separated in time. For your dog to connect something she does with the consequences of that behavior, the consequences must be immediate 4., you have to catch her messing around in the kitchen and punish her on the spot.
5.. When training your dog, you should respond the same way to things she does every time she does them. For example, if you sometimes touch your dog when she jumps up to greet you but sometimes yell at her instead, she'll definitely get confused. How can she know when it's okay to jump up and when it's not?
A.Consequences must be consistent
B.Understand how your dog learns
C.If you want to keep your dog safe
D.If you want to discourage your dog from doing something
E.We adore them for their loyalty, unconditional affection, and passion for life
F.Training your dog well will improve your life and hers, enhancing the bond
G.Other methods mainly focus on teaching dogs what you want them to do
More than a billion people around the world have smartphones, almost all of which come with avigation (导航) apps such as Google or Apple Maps. This raises the questions we meet with any technology: What skills are we losing? What abilities are we gaining?
Talking with people who're good at finding their way around or using paper maps, I often hear lots of frustration with digital maps. North/South direction gets messed up, and you can see only a small section at a time.
But consider what digital navigation aids have meant for someone like me. Despite being a frequent traveler, I'm so terrible at finding my way that I still use Google Maps every day in the small town where I have lived for many years. What looks like an imperfect product to some has been a significant expansion of my own abilities.
Part of the problem is that reading paper maps requires specific skills. There is nothing natural about them. In many developed nations, including the U. S., one expects street names and house numbers to be meaningful references, and instructions such as "go north for three blocks and then west" make sense. In Istanbul, in contrast, where I grew up, none of those hold true. For one thing, the locals rarely use street names. Why bother when a government or a military group might change them again? Besides, the city is full of winding, ancient alleys that meet newer avenues at many angles. Instructions as simple as “go north" would require a helicopter or a bulldozer (推士机).
Let's come back to my original questions. While we often lose some skills after leaving the work to technology, it may also allow us to expand our abilities. Consider the calculator: I don't doubt that our arithmetic skills might have dropped a bit as the little machines became common, but calculations that were once boring and tricky are now much more straightforward and one can certainly do more complex calculations more confidently.
1.What is the drawback of digital maps?
A.They aren't connected to smartphones.
B.They cost too much to download.
C.They leave some users frustrated.
D.They mix up the south and the north.
2.What's the author’s attitude toward digital maps?
A.Doubtful B.Supportive
C.ambiguous D.Uncaring.
3.What's the fourth paragraph mainly about?
A.The differences between Istanbul and the U. S.
B.The miserable life of people in Istanbul.
C.The necessity of asking local people in Istanbul.
D.The ancient alleys and new avenues in Istanbul.
4.What does the author suggest in the last paragraph?
A.When technology closes a door, it opens one as well.
B.Two paper maps are better than a digital one.
C.Technology is not developed in a day.
D.No calculators, no digital maps.
The African Continent has various habitat types, but savanna (热带草原) ecosystems cover approximately half. And where there is savanna, there is fire. "It's an important part of the ecology of the system," says University of Liverpool ecologist James R Probert. Burning allows grasses to take the lead by keeping taller bushes from occupying the land, Loss of grasses could push out species such as wildebeest (牛 羚 ), which are famous for their splendid annual migration.
A decade ago researchers put decreasing fires within Tanzania's Serengeti National Park down to the recovery of wildebeest population following an epidemic of rinderpest, a viral disease. When millions of wildebeest feed on grass, they remove fuel from the land, making fire less frequent and less severe.
But Probert and his colleagues found that even after wildebeest populations had stabilized by the mid-1990s, fires continued to decrease in the same area. Their analysis of satellite data showed that the region experienced a 40 percent reduction in wildfires between 2001 and 2014- in line with dramatic increases in farm animals in the area.
If you have lots of farm animals eating the grass, then you have less fire. That’s well known Probert says. "But I don’t think anybody had realized the degree of the decline in fire and linked it to farm animals before.”
This is a really interesting pattern, "says University of Guelph biologist John Fryxell, who was not involved in the study. He cautions, however, that 15 years' worth of data is still a fairly small amount of information from which to draw final conclusions. "What a short-term connection like that suggests is that there's something interesting here that could provide the grounds for a deeper experimental analysis, "he adds. That research could include artificially controlling fire frequency or grazing intensity (放牧强度) in certain areas and then monitoring the land's response over time.
1.What do we know about fires in savanna?
A.They only happen once in a decade.
B.They are harmful to the growth of grasses.

2.According to Probert, what led to decreasing fires?
A.The spread of a disease. B.The increase in farm animals.
C.The change of the climate. D.The stability of wildebeest population.
3.What does John think of Probert's study?
A.It might help recover the land in savanna.
B.It could lead to further studies on savanna fire.
C.It has proven the link between fires and grasses.
D.It offers enough information for final conclusions.
4.What is the best title for the text?

Andrea Yoch loves her adult sons, but would also love to not live with them. This is especially true in the 2, 200-square-foot rental in St. Paul, where she and her husband moved after the boys left their childhood home (a 5,000-square-foot property with a pool). But now Ben, 20, and Ryan, 23 are crammed with their parents in a house where a movie playing in one room can be heard in almost any other.
After her sons showed up due to the lockdown after the Coronavirus crisis struck- Ben from Boston, where he is a college student, and Ryan from New York, where he was starting out as an assistant advertising account executive- Ms. Yoch rushed to set up temporary offices in a bedroom and a basement that now also functions as a super crowded gym. "I would give anything for them to restart their lives, "she said.
As the pandemic （流 行 病） continues, Wall Street bankers, Uber drivers, academics, artists and many other adults have given up their independent lives and migrated home. Some fled heavily populated cities for the rural suburban houses where they grew up and the promise of home-cooked meals and free laundry. Others ended up in downsized spaces designed for empty nesters or in apartments already shared with other family members, such as grandparents or teenage siblings.
Parents caught by the increase of layoffs and canceled contracts found themselves feeding grown children who were in the same position. Mothers who had grown accustomed to freedom were suddenly expected to go back to cooking and cleaning.
“Some parents see this as a welcome surprise, but it can also add a lot of financial stress," said Lindsey Piegza, chief economist at the investment bank Stifel. You can't assume that parents are necessarily in a better-off position than their adult children: a lot of Americans live paycheck to paycheck and don’t have enough savings to accommodate extra people living in their households.”
1.Which word best describes Ms. Yoch's life with her two sons?
A.Exciting B.Inconvenient
C.Satisfying D.Disappointing
2.What does the underlined phrase "empty nesters" in Paragraph 3 refer to?
A.People without jobs.
B.Children staying abroad.

A.Because they want their kids to be independent.
B.Because they don’t like to do all the laundry.
C.Because they are in no better financial situation.
D.Because they have sold or rented out their houses
4.What is the text mainly about?
A.The generation gap between parents and their children.
B.The life young people used to live before going to college.
C.The parents' life being affected by children in the lockdown
D.The economic crisis brought about by the deadly coronavirus.
