A student's life is never easy.{#blank#}1{#/blank#}A lot of preparations are needed so you can be sure to go back home with a diploma and a bright future waiting for you. The following are some basic things you need to do before seizing your passport and boarding the plane.

    Knowing the country.

    You shouldn't bother researching the country's hottest tourist spots or historical places. You won't go there as a tourist, but as a student. I'll be helpful to read the most important points in their history and to read up on their culture.{#blank#}2{#/blank#}You surely don't want to face legal problems, especially if you're away from home.

    Studying their language.

    Don't expect that you can graduate abroad without knowing even the basics of the language. Before leaving your home country, take online lessons to at least master some of their words and sentences.{#blank#}3{#/blank#} Doing this will also prepare you in communicating with those who can't speak English.

    {#blank#}4{#/blank#}

    Check the conversion(兑换) of your money to their local currency, set up your bank account so you can use it there, get an insurance, and find an apartment. The Internet or your intended school will be very helpful in finding an apartment and helping you understand local currency.

    Remember, you're not only carrying your own reputation but your country's reputation as well. If you act foolishly, people there might think that all of your country men are foolish as well.{#blank#}5{#/blank#}

A. Packing your clothes.

B. And it is even more difficult if you have to complete your study in a foreign land.

C. That would surely be a very bad start for your study abroad program.

D. This will be useful in living and studying there.

E. Most importantly, read about their laws.

F. Going with their trends will keep it from being too obvious that you're a foreigner.

G. Preparing for other needs.

    The goal of homework is to help students remember and understand what they learned in school that day. It can also help teach them independence and time-management and planning skills, which are keys to success in the real world.{#blank#}1{#/blank#} Here are some successful habits of how to do a good job of homework.

Set the stage.

    Your children need a quiet spot to do their homework.This should be the same place every day, whether it is at the kitchen table or at their desk in their room.{#blank#}2{#/blank#}You can take the time to work on a quiet task of your own, whether it's paying bills, reading the newspaper, or planning the next day.

Time it right.

    Homework for young children should be done when your children get home from school, because the information is still fresh in their minds and they have enough energy. Have your kids eat some snacks and talk about their day with you.Then have them start their homework.{#blank#}3{#/blank#}

It's not your homework: it's theirs.

    You need to be involved in homework to see what your children are learning and how well they know what they need to know.{#blank#}4{#/blank#}But guide them if they are struggling. You want them to get the feeling of pride and accomplishment on their own.

    {#blank#}5{#/blank#}

    Let your children know how grown up it is for them to have homework and how proud you are of them. Try to instill (灌输）into them that it is “fun” to be able to do the assigned tasks. Let them show you their work, praise them for finishing their homework, and always do it with a smile.

A. Be hopeful and confident.

B. Get excited and be positive.

C. Be nearby while they do their homework.

D. Be sure not to do the homework for your children.

E. That means the television is shut off, even for you.

F. A small amount of homework also has a great influence on students.

G. Arrange other activities for later in the day so kids can get their homework done first.

    In the future we might live somewhere other than Earth, like Mars. Some people ask how this will be possible. Well, Mars is in fact a lot the same as the earth. The days are almost the same as those on the earth. However, the two planets vary in temperature.

    Since there is mostly carbon dioxide on Mars, it would be quite difficult for a human to just land on it. So, special types of homes and space suits have to be designed. The space suits should be almost like the ones astronauts use now, and except that they have to be warmer so that the astronauts can survive the cold temperatures. The space suits must also be able to withstand (承受) high pressure and potentially dangerous radiation that can kill.

    The houses should be similar to our homes today with a slight difference. All of the houses and other buildings should be built inside a large dome (圆顶状物) or bubble. The domes should be made out of glass, and would also be able to prevent radiation from affecting the people inside. The domes will be connected to a machine (like plants which turn carbon dioxide into oxygen).

    With Mars' population growing, how would the people on its surface get fresh food and water? Just like humans use domes, they can also use domes to grow plants. However, the domes where the plants are grown must be built to expand. Once we upgrade the domes to a larger size then we can grow more food by cultivating (种植) more plants. To get the food or come in connect with other domes, there will be long narrow tunnels like roads that connect to each dome separating them by several doors so that the pressure in each dome can remain the same.

    On Mars, so many other things are available to us. As humans, we can have access to rare and fairly expensive metals that aren't very easy to get hold of on Earth, and a colony on Mars enhances (提高) our chances of finding these metals. So when someone here on Earth says that going to Mars is impossible, please tell them that they'll never know it until they try and they may try very soon. After all it's our future. Why not make it on Mars?

Everyone gets anxious when the world takes an uncertain turn. And often, we treat that anxiety with a little panic buying.

A study published last year in the Journal of Consumer Research found that people buy things in troubled times as a means of keeping control over their lives. The researchers noted that utility items — specifically, cleaning products — tend to move most quickly from store shelves. The hoarding (囤积) of toilet paper, as perhaps the most fundamental cleaning product, may represent our most fundamental fears. An invisible enemy moves slowly and quietly towards us. We need to hold on to something in uncertain times. Maybe a hoard of toilet paper brings promises.

The thing is, it's not actually going anywhere. For all the sharp words and even sharper elbows thrown around by the crazy toilet paper shoppers, they seem to be missing one essential fact: There is no toilet paper shortage.

As The New York Times points out, shop owners that see their shelves emptied often fill up the shelves again in a day, often in just a few hours.

"You are not using more of it. You are just filling up your closet with it," Jeff Anderson, president of paper product manufacturer Precision Paper Converters, tells the Times.

The thing is, the toilet paper-obsessed shoppers have been infected with something many times more contagious (感染性的) than any coronavirus: fear.

"People are social creatures. We look to each other for cues for what is safe and what is dangerous," Steven Taylor, a clinical psychologist at the University of British Columbia, tells Fox News. "And when you see someone in the store panic-buying, that can cause a fear contagion effect. People become anxious ahead of the actual infection. They haven't thought about the bigger picture, like what are the consequences of hoarding toilet paper."

Bruce, a parrot missing part of his beak （喙）,  creatively uses stones to clean feathers （羽毛）,  highlighting advanced intelligence in parrots. 

Bruce lost the upper part of his beak in 2012 and was sent to live at a reserve in New Zealand. The defect made Bruce unable to search for food on his own, let alone keep his feathers clean with his beak. But in 2021, when comparative psychologist Bastos arrived at the reserve with colleagues to study parrots, zookeepers reported something strange：Bruce had seemingly figured out how to select and use small stones to clean his own feathers with his beak. 

Over nine days, the team kept a close eye on Bruce, quickly taking, videos if he started cleaning his feathers. It turned out that Bruce had indeed invented his own way to do so, the researchers reported in Scientific Reports. 

"It's crazy because the behavior was not from the wild, " Bastos says. When Bruce arrived at the reserve, he was too young to learn how to clean his feathers. And no other bird in the reserve uses stones in this way. "It seems like he just invented this tool use for himself, " she says. 

Tool use is just one of parrots' many talents. They're famous for copying and even understanding human speech. Some species can also solve complex puzzles, like how to enter a covered rubbish bin or practice self-control. 

For a concept as abstract （抽象的） as intelligence, it's challenging to develop a definition that applies across animals. Researchers often point to features once thought to make humans special—enhanced learning, memory, attention and movement control—as signs of advanced skills. However, many of these abilities can also be seen in parrots, as well as other animals like chimpanzees, dolphins and elephants. 

"Parrots are our evolutionary （进化的） mirror image. These brilliant birds may teach us about how humanlike intelligence can appear, " behavioral ecologist Antone wrote in his 2022 book The Parrot in the Mirror. With powerful brains and a preference for words, these birds are "the very best example, " he writes,  "of nature's 'other try' at humanlike intelligence. "
