There's no doubt that man is the smartest. But do you know what other animals are smart, too?

Dolphins

    Dolphins are very smart. Most of the “tricks” they're taught to do are actually behavior they would engage in on their own. They love to play, race and generally enjoy their life to the fullest. They speak a language we have yet to completely understand and like all civilized creatures, dolphins' mothers always provide their young children with guidance and possibly, love.

Great apes

    The great ape family primarily consists of gorillas, chimpanzees and orangutans. Their brain chemistry is so similar to humans' that NASA once used chimpanzees in place of astronauts during many dangerous missions. Gorillas have been taught sign language and orangutans exist in complex familial relationships.

Elephants

    Everyone has heard the phrase “an elephant never forgets”. Elephants establish long-term friendships, recognizing and remembering their friends years later. If an elephant comes upon a fallen friend, it has even been known to feel sad.

Parrots

    As proved by this list, parrots are very smart. They are also the only animals listed that can actually hold a conversation. Some parrots know hundreds of words by imitating humans. The birds are also capable of remembering words and using them intelligently in response to situations.

    Most birds produce short, simple calls, but songbirds also have the ability of many complex vocal (发声的) patterns that help them attract mates, defend territory (领地), and strengthen their social bonds. Each songbird species has its own unique song patterns, some with characteristic regional dialects. Experienced listeners can even distinguish individual birds by their unique songs.

    A lot of what scientists know about bird song comes from studying zebra finches. A baby male zebra finch typically learns to sing from its father or other males, starting while it's still a baby bird in the nest. First comes the sensory learning stage, when the baby finch hears the songs sung around it and commits them to memory. The bird starts to vocalize during the motor learning stage, practicing until it can match the song it memorized. As the bird learns, hearing the tutor's song over and over again is helpful — up to a point. If it hears the song too many times, the imitation (模仿) becomes worse -- and the source matters. If the song is played through a loudspeaker, he can't pick it up as easily. But hide the same loudspeaker inside a toy painted to look like a zebra finch, and his learning improves.

    What if the baby never hears another zebra finch's song? Interestingly enough, it'll sing anyway. Isolated finches still produce what are called innate songs or isolate songs. A specific tune might be taught, but the instinct to sing seems to exist in a songbird's brain. Innate songs sound different from the “cultured” songs learned from other finches - at first. If isolate zebra finches start a new colony, the young birds pick up the isolate song from their fathers. But the song changes from generation to generation. And after a few generations, the melody actually starts to resemble the cultured songs sung by zebra finches in the wild.

    For many high school students, it seems that there is never enough time. There are several steps you can take to organize your time better.

    ⒈Make a to-do list every day. It makes it easy to plan any activities or meetings you may have in addition to homework. Be sure to set priorities (优先的事物).{#blank#}1{#/blank#}

    ⒉Use spare time wisely. Do you have a study hall? Instead of wasting that time, read a book or do homework.{#blank#}2{#/blank#} If a friend asks you to do something and you have homework to do, realize which is more important and see your friend later.

    ⒊Decide on the time that is good for you to do certain things. If you are more of a morning person, try getting up an hour earlier and do schoolwork before school. Review your notes every day.{#blank#}3{#/blank#} If you spend a few minutes at the end of every day going over what you learned, it will mean less time studying when it is time for the exam.

    ⒋{#blank#}4{#/blank#}Studies have shown that getting enough rest helps your memory. When you are tired, everything seems more difficult. It is best to stay on a regular sleeping cycle as much as possible.

    ⒌Tell your friends and family about your work timetable. Explain that you will be working at certain times and ask them not to disturb you.{#blank#}5{#/blank#} you can call your friends later.

A. Set goals for yourself.

B. Get a good night's sleep.

C. Do the most important tasks first.

D. And also, do not be afraid to say “no”.

    Students in many countries are learning English. Some of these students are little children. Others are teenagers. Many are adults. Some learn at school, others learn by themselves. A few learn English over the radio, on TV, or in films. One must work hard to learn another language.

    Why do all these people want to learn English? It's difficult to answer this question. Many boys and girls learn English at school because it is one of their subjects for study. They study their own language, math, English, and so on. Some people learn it because it is useful for their work. Many people learn English for their work and higher studies, because at colleges or universities some of their books are in English. Other people learn English because they want to read newspapers or magazines in English.

    Are you suffering from FOMO—that is, Fear of Missing Out? Research shows that a growing number of young people are with worrying reasons for their sleep and schoolwork.

    {#blank#}1{#/blank#}You aren't able to do your best unless you sleep well. Most experts agree that the optimum（最适宜）number of hours is eight, and this has been accepted as common sense for as long as I can remember. However, I was young once and know most of you get much less sleep than that.

    I read an interesting article in a teachers' magazine recently.{#blank#}2{#/blank#} Worryingly, the results showed that teenagers are facing a new problem. They may go to bed and get up at appropriate times, but a growing number are waking up in the middle of the night, not to use the bathroom or have a snack, but because of FOMO.

    According to the article, the number of students waking up during the night to check social media is growing. Afraid of missing a comment or opportunity to take part in a chat, teenagers are waking at all times of the night, going online and getting involved. {#blank#}3{#/blank#}

    Experts are worried about this growing trend and the report reveals some worrying statistics: 23% of 12 to 15-year-olds wake up nearly every night to use social media. {#blank#}4{#/blank#} One in third of the students are constantly tired and unable to function to their full capacity.

    So I'd like to ask you to be responsible when it comes to social media. Switch off your devices at night. The world won't end and your social media will be waiting to greet you in the morning! {#blank#}5{#/blank#}

A. But things are getting out of hand.

B. I give you my word that you won't have missed anything important.

C. Another 15% wake up at night once a week for the same reason.

D. They did a study of 848 students in Wales.

E. FOMO is the fear that everyone else is having more fun and more excitement than you.

F. All happens when they should be sound asleep.

G. Everybody knows how important it is for students to get a good night's sleep every night.

    When it comes to learning a foreign language, many people wonder if they will be able to memorize enough vocabulary. But this question never happens about their mother tongue, and yet, it was a foreign language once. However, among all the questions that new parents ask, no doctor has ever heard: "Will my baby be able to learn my language?" Be honest, do you know all the words of your mother tongue? The answer is: "no".

    New words, and new ways of using old words, appear every day. Twenty years ago, who could have been able to understand a sentence like this: "Click here to download your digital book."? Nobody. You never stop learning new vocabulary and you never know how long you will need it.

    Sometimes, you have the word on the tip of your tongue...and it sticks there! But you do know this phenomenon(现象) and don't think that it is because of a bad memory. You should not give this phenomenon more importance in the language you are learning than in your mother tongue.

    You need to learn only 2000 or so basic words to be able to create any phrase you need. You can't avoid some work in order to learn these necessary words and all the more if you want to learn quickly. And before you consider buying into any method, be sure it is right for you. It is not wise to depend on any method based upon mnemonics(记忆群). The first few words seem very easy to learn, so you buy the course, but then you discover quickly, though too late, that a dozen words later, it is all the more difficult to learn a new word when you have also to learn the trick to memorize it.
