As is known to us all, everyone can make mistakes. But don't worry about it. The following is what we should do when we make mistakes.

●Just admit (承认) it. Don't think that our mistakes are caused by others. {#blank#}1{#/blank#} Don't blame other people, and don't cheat ourselves, either.

●{#blank#}2{#/blank#} In order to stop the problem from getting worse, we should act quickly to solve it. If we don't act and deal with the problem quickly, it'll only make us feel more stressed. Also it is necessary to make a plan of action and correct the mistake according to it. {#blank#}3{#/blank#}

●{#blank#}4{#/blank#} Those who have made the most mistakes can get an A, for they are the ones who have learned the most. The more we learn from our mistakes, the cleverer we are.

●Think about what we can learn from our mistakes. What caused us to make the mistake? {#blank#}5{#/blank#}When we act with a method to get a good result, do it that way next time. If we don't, we should stop, think about it, change it and try again.

A. Solve it at once.

B. So be away from stress.

C. Don't be afraid of failure.

D. So decide quickly and act.

E. Realize that making mistakes is the best way to learn.

F. How can we avoid making the same mistake in the future?

G. Be brave and face the fact that we have made the mistakes.

    Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have recorded how ants choose their next queen — the female whose job is to produce eggs.

    New technology is helping to improve researchers' understanding of the insects. But there is still a lot to be learned.

    Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide.

    David Hu is an engineer with the Georgia Institute of Technology, also known as Georgia Tech, saying, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at keeping this network. "

    David Hu and other Georgia Tech researchers wanted to study ants and the secret of their engineering. They froze ant rafts and then looked at them with the help of computed technology, or CT images. The pictures showed that larger ants serve in central positions to which smaller ants hold. The larger ants create pockets of air that keep the insects afloat.

    Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal.

    Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen.

    Have you ever heard someone say "You totally look like you're a Jessica" or something similar? People seem to think that they know what kind of person a "Jessica" or a "Michael" looks like. Why is this?

    According to a study published in the Journal of Personality and Social Psychology, humans tend to associate people's names with their appearances, and can even guess someone's name based on how they look.

    Researchers at the Hebrew University of Jerusalem, Israel, collected thousands of photos of people's faces. They labeled (贴标签于) each photo with four names. Then, they asked volunteers to guess which of the four names was correct.

    The volunteers were able to guess the right name 38% of the time. It seems that certain characteristics of faces give them clues about someone's name, Reader's Digest reported.

    However, this only worked when the volunteers looked at names from their own culture. In addition, the volunteers were not as good at guessing the real names of people who used nicknames(昵称)more often than their real names. This may show that a person's appearance is affected by their name only if they use it often.

    "This kind of face-name matching happens because of a process of self-fulfilling prophecy (预言), as we become what other people expect us to become," Ruth Mayo from tile university told science news website EurekAlert.

    Earlier studies have shown that gender (性别) and race stereotypes (刻板印象) can affect a person's appearance. The researchers believe there are also similar stereotypes about names. For example, people tend to think that men named Bob should have rounder faces because the word itself looks round. People may think that women named Rose are beautiful. They expect them to be "delicate" and "female", just like the flower they are named for.

    Have you ever complained, "I remember reading it, but I can't remember what it said? " then you should try the SQ4R reading method.

    S = Survey. The first step is to take a few minutes skimming the chapter. Don't read it yet, just look at topic headings, key words, and read the summary.

    Q = Question. As you prepare to read the chapter, turn the first topic into a question or two. As you read, seach for the answer. This will help you organize your reading-find the parts that answer your question, give an example, consist of related information or that may answer a later question. Most importantly, this gives you a reason to read the next paragraph.

    R = Read. Read in short "bites" (部分), then determine how that answers question(s) you originally posed (提出). Often as you read other questions will arise.

    R = Recite. Now can you answer your question(s) in your own words? If you can't, reread the material to find the answers or determine if you need to change the question. You are rehearsing (重复，默诵) for the time when you will need o know the answer. A good technique for rehearsing answers is to briefly jot down (草草记下) the key words that remind you of the essence of the answer without writing down every detail.

    R = Relate. Most of us try to relate what we are reading to what we already know. It is always easier and more satisfying to remember information that is personally meaningful. Everything has a context. Some information may take more reflection before you are able to grasp its relationship with what you already know while other information may simply require more research, to understand how it fits with other data.

    R = Review. One way to minimize memory decay (衰退) and to store the material you have studied firmly in your mind is by reviewing it. After you finish reading the entire chapter, skim back over it and any note you made.

    Effective studying requires effective reading. Rather than getting "intellectual indigestion" while reading straight through a chapter, instead you should stop to survey, question, read, recite, relate, and review so as to improve your reading comprehension.

    For many creatures, the ocean is a terrifying place. Several marine animals have declined as a result of overfishing and pollution. But cephalopods(头足动物) — a type of invertebrate(无脊椎动物) that includes octopuses, cuttlefish, and squid, have seen a dramatic increase in their numbers over the past 60 years.

    Zoe Doubleday, a scientist at the University of Adelaide, in Australia, conducted a study of cephalopods recently. She points out that their population rise is due to the animals' unique traits.

    The creatures can change their color and body shape. They are fast-growing and live for only one or two years. "This allows them to adapt to changing environmental conditions more quickly than other marine species," Doubleday says.

    "Rising sea temperatures may be speeding up the animals' life cycle. They may be growing faster and producing more young."

    Cephalopods live in all of the world's oceans. They can be found in waters from the freezing polar regions to the warm tropic regions. Because they adapt so easily to their environment, the animals are called "the weed of the sea".

    Will octopuses, cuttlefish, and squid take over the world one day? Some people may wonder. According to Doubleday, that is unlikely. The rise in cephalopod populations could slow down if the animals run out of prey(被捕食的动物) and start feeding on one another. Overfishing could also have an impact on their numbers.

    For now, the cephalopod population boom is good news for them and some other sea creatures. "Increases in cephalopod populations could benefit predators(捕食性动物) such as marine mammals and seabirds, which rely on cephalopods for food," Doubleday says.

    Many languages are disappearing and languages such as English, Spanish and Chinese are increasingly taking over. Yet Maori promises to have a rosy future given that New Zealanders are showing great enthusiasm for speaking this local language.

    A "Maori renaissance (复兴)" blossomed in the 1970s as language activists championed their cause and Maori fought for greater political power. But until 2013, just 3.7 percent of New Zealanders spoke the language fluently, and many predicted it would soon die out. Now New Zealand's government is erasing prejudice and struggling to increase the percent of population who can speak basic Maori by 2040 to 20. Prime Minister Jacinda Ardem said last month that her newborn daughter would learn both Maori and English. "It's an official language, so why should we dismiss its universal availability and its much more common use?" said Ms. Ardem, adding that she also planned to study the language. Grassroots are also spreading it by word of mouth Answering the phone with the greeting "kiaora" (hello) or ending an email withunga mihi' (thanks) has become a fashion. Maori is gradually becoming part of New Zealand's mainstream popular culture.

    Ajit Kumar Samah, a famous professor in Auckland University, published a book—Coniagious: why Maori catches on, where he introduces readers to the popularity of Maori and expresses his great anxiety for the lack of teachers who have the competence to teach the Maori language.

    People are not on the same wavelength, however. Suggestions on officially replacing English-language place names with traditional Maori ones have been rejected. So when a police car was designed using Maori, it was condemned by some as ridiculous because of the higher Maori rates of arrest and imprisonment.
