1 . Many children want to have their own pets, but how to be a good pet owner? Besides giving them food and water, what else can we do to give our pets much love?
Provide your pet with the correct diet.
If you prefer to change the previous diet of your pet, do it slowly so that they adjust (适应) properly.
Clean their housing often.
Clean your pet’s home at least once a week and any other times if necessary. Generally, a pet’s home should be clean so it is a good environment for the animal.
Keep your pet clean.
If you have a dog that always plays in the mud, it’s necessary to give it a shower every day!
Train your pet.
Put a collar on your pet with your personal information and the pet’s name. Remember to close the cage door so there is no chance of escaping and being in an unsafe place.
| A．Never hurt or harm your pet. |
| B．Be an owner with a sense of duty. |

2 . When I was seven, my family and I were coming back from a T-ball game. In our driveway, we spotted two adult geese and a small gosling. The adults were frightened by our return and flew away, but their baby was still too young to fly and couldn’t follow.
Hours passed and night fell. The tiny little thing was wandering around our yard, unaware of what could happen, and it was clear that the gosling needed protection, warmth and food to make it to the morning. At that point, we had to bring him into our backyard.
We all pretty much slept with one eye open for several days. Each morning, we would try to rush the goose over to his parents, who kept coming back to our yard. He wouldn’t go to them, though, and they wouldn’t come close enough to claim him. The young goose had clearly decided we were his new family, and my twin sister Joanna called the little guy Peeper.
Almost a year passed and we settled into a routine filled with feathery hugs and company. One evening my uncle came over, and my dad threw Peeper up into the air to show he could fly around the house, but this time, Peeper just flew off. Everyone was very sad. Twenty years passed, and Peeper became a fond memory for my family.
In 2019, an aging adult goose made his way back to my home. At first, I assumed it was just another Canada goose. After two weeks of the goose coming back repeatedly, it became clear to me that this wasn’t a random goose. He did all of the same things Peeper used to, like trying to come in through the front door and sleeping in our enclosed pool area. Besides, this goose responded to the name Peeper. Much to my amazement, my old best friend had returned, 20 years later.

5 . KK was around five years old when he showed up at the front gate of my house in 2012. And clearly he was used to a life outside. While mostly happy indoors, he did expect to be let out. He would go out and do his things, and then come back and hang out inside until his next need for an outside visit arose.
When Julien, my second cat, showed up in 2013, having two cats wanting in and out at different times was more difficult. After careful consideration, I finally decided to put in a cat door. It allowed KK and Julien to come and go as they wanted without waking me up at 5 am to go outside or at 5:10 am to come back inside. It also saved my door, which KK was always abusing（虐待） as his way of letting me know I was being too slow in opening the door for him or not responsive（应答的） at all.
When my mother passed away in the spring of 2014, leaving her young cat without a forever home, I decided to take her. Once being an indoor/ outdoor cat, Sissy obviously didn't want to suddenly to be kept indoors. She also wanted to be able to get away from the other two cats, as she was used to being in a single cat home.
After KK, Julien and Sissy had all become used to their life of coming and going as they pleased, it pretty much guaranteed（保证） that all future cats would have the same right. And now have seven cats that come and go as they please. Letting my cats go outdoors isn't due to my not caring or getting them out of my head. On the contrary, it is because I love them so much and want them to have the best life possible.

6 . In the foot hills of Chianti Classico in central Italy, Elena Lapini and her husband make their way down neat rows of grapevines and inspect their fruit. The grapes are ripening too fast under the hot sun. Too much bronzing on the vine, they will wither into raisins (葡萄干), turning the wine into a sour, unpleasant blend. Getting the harvest date right is crucial for this reason, but climate change is making it increasingly hard.
An analysis of harvest dates going back to 1354 in France found that air temperatures have increased so much that grapes are now harvested two weeks earlier than in medieval times. Elizabeth Wolkovich, a biologist researching the impact of climate change on vine yards, says rising temperatures are changing the taste of wine itself.
For some cooler regions, warming conditions have allowed winemakers to grow more flavorful berries and enjoy longer growing seasons. Germany, best known for its Riesling white wines, has become more favorable to heat-loving grapes. Parts of Britain where it rains frequently now have the perfect climate to make sparkling wines, giving British bubbly from Kent and Sussex a fair fight against French champagne. But in warmer places like France, Italy and Spain ripening grapes at a higher temperature means more sugar and less acid in the berry, making high-alcohol, honey-like wines.
Climate change is also threatening the world's wine supply. In April producers in Italy and France found themselves lighting thousands of bucket-sized candles to warm the air against a killer frost that threatened to destroy buds emerging with the first warm spells of spring. In some regions the frost wiped out 90% of the crop, resulting in an estimated €2bn loss, French officials described it as “probably the greatest agricultural catastrophe at the beginning of the 21st century”.

7 . Today, methane(甲烷) is a central but under-appreciated part of the fight against climate change. Human activity releases far less methane than carbon dioxide, but methane packs a heavier punch. Over the course of 20 years, a ton of the gas will warm the atmosphere about 86 times more than a ton of carbon dioxide. Chief among the reasons for methane emissions(排放) are the gassy output of raising farm animals (cows release it most), rice production (certain environments involve micro-organisms that make it) and the fossil fuel industry(pipelines leak it) .
Carbon dioxide remains in the atmosphere for centuries, making it hard to reduce its concentrations. By contrast, methane has a half-life of roughly ten years. If new emissions can be cut to below the rate at which old emissions reduce, the concentration of methane remaining in the atmosphere will soon fall, slowing global warming.
A big step would be to stop millions of tons of methane from leaking out of fossil fuel industry each year. Natural gas operators will be able to sell more gas in exchange for an acceptable investment so as to monitor and repair leaks. The International Energy Agency estimates that 40% of methane emissions from fossil fuels can be cut at no cost for firms.
The harder task is to reduce emissions from agriculture, but even here farmers can draw on new ideas, including developing new forms of feed for farm animals, and changing how rice field is irrigated.
However, politicians and the public tend to ignore the effects of cutting methane emission. But dealing with the gas with the efforts of the ordinary people would have a large effect at a relatively low cost.

8 . Every 17 years, billions of insects, known as the cicadas (蝉) of Brood X, rise from the earth This year, perhaps, there will be trillions! Brood X is one of the largest groups of cicadas and will appear sometime in May, 2021 in 15 states, from Georgia in the south to New York in the northeast.
Many scientists and insect lovers say they’re looking forward to the red-eyed insects after a 17-year wait. One of them is Mike Raupp, an insect expert at the University of Maryland. " What they're waiting for is the soil temperatures to reach about 18℃, and then they're going to be and out of the ground. ”
When the insects come out of the ground, they will drop their skin, get their wings and try to go up on the treetops to escape from the predators (天敌). Once on the treetops, the male cicadas will "sing " their mating songs to draw the females. If she likes the singing, they will mate and reproduce. About six weeks later, the nymphs (蛹) will fall off the treetops and go into the ground Underground, the insects will quietly feed off tree roots and wait for another 17 years to start the party on the treetops all over again.
Raupp explained that some cicadas appear every year, but they have a much shorter life cycle and stay alive in two ways. They are green and can hide in nature. Also, they can fly very fast. So, they avoid being caught by predators. Periodical cicadas like Brood X have neither of those lifesaving methods. To continue the species, he said billions of periodical cicadas will appear all at the same time. So, their predators can't eat all of them. Also, by coming out every 17 years, they aren’t a dependable food source for predators and simply outlive them.

10 . Scientists often compare coral reefs(珊瑚礁) to underwater rainforests, yet unlike the leafy plant base of a forest, corals are animals. The soft creatures are naturally half-transparent and get their brilliant color from algae(藻类) living inside them. When corals experience stress from hot temperatures or pollution, they halt the interdependent relationship with algae, typically pushing them out and turning white. Corals are still alive when they are white, but they're at risk and many eventually die, turning dark brown.
Scientists around the world are looking for means to protect and maybe increase corals. One common option is to create more protected areas — essentially national parks in the ocean. Beyond nature preserves, some conservationists are looking to more hands-on methods. One research center in the Florida Keys is exploring a form of natural selection to keep corals remaining. The reef system in the Keys has been hit hard by climate change and pollution, which is especially tough, because corals there help support fisheries worth $ 100 million every year.
To keep the wild ecosystem alive, Erinn Muller, the center's director, and her team are harvesting samples of the corals that survived the environmental stress naturally, keeping them to make them reproduce, and then reattaching them to the reef. They have 46,000 corals on plastic frames under the sea. So far, the center has regrown over 70,000 corals from five different species on damaged reefs.
In The Bahamas, Ross Cunning, a research biologist at Chicago's Shedd Aquarium, focuses on corals with genes that could make them natural candidates for restoration projects. He published a study of two Bahamian reefs, one that survived an extreme 2015 heat wave, and one that didn't. "We think their ability to deal with these higher temperatures is built into their genes," says Cunning. There's evidence of corals evolving more quickly to resist rapidly warming climate. The big question scientists need investigate, adds Gunning, is how much more heat corals can adapt to.
