Why do parents have such a difficult time to communicate openly and honestly with their teens? For this, there are many reasons but most of them stem from not being able to properly understand their teens. It is a dangerous gap because parents will have to communicate with their teens about a wide variety of issues during the most important years of their lives. Thus, parents must know how to communicate openly and honestly with their teens.

    Here are a few tips to make communication easier between parents and teenagers.

    1）Try not to talk down to your teens. Make them feel as if their views really matter, which not only helps your discussions with your teen but bring you closer to him.

    2）Imagine what it would be like to be a teen. Try to remember some of the negative feelings you experienced as a teenager and apply it to your teen's situation.

    3）Never make negative remarks to your teen about what he has said or done.

    4）Remember how much courage it would have taken for your teen to come and talk to you about his personal issues. So listen respectfully.

    5）Don't ignore your teen's feelings because it is usually a cry for help. For instance, if your teen is unusually angry, it may be time to spend a bit of quality time with your teen to determine what is wrong and where he is coming from.

    It is, therefore, necessary for parents to strive to keep lines of communication open at all times with their teens. Try to remember what it was like to be a teenager and how vulnerable（脆弱的）you felt. Then you will be well on your way to help your teen communicate more openly and honestly.

    When you're in high school, it can be difficult to find a job. You may not have much, or any, formal work experience and there aren't many jobs available for teenagers.

    Antaretica's ice-white environment is going green and facing other unexpected threats. Scientists say that as temperatures go up in the polar region, invading (入侵) plants and insects, including the flies, cause a major conservation threat.

    More and more of these invaders, in the form of larvae (幼虫) or seeds, are surviving in coastal areas around the South Pole, where the temperature has risen by more than 3℃ over the past three decades. Glaciers have retreated, exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before-providing potential green homes for invaders.

    “The common house flies are a perfect example of the problem the Antarctic now faces from invading species,” said Dominic Hodgson of the British Antarctic Survey. “It comes in on ships, where it exists in kitchens and then at bases on the continent. It now has an increasing chance of surviving in the Antarctic as it warms up, and that is a worry. Insects like the house flies carry bacteria that could have a deadly effect on native lifeforms.”

    The Antarctic has several native species of insects. Together with its native mosses, these are now coming under increased threat from three major sources: visiting scientists, increasing numbers of tourists and global warming. However, it is global warming that is the main driver of the greening of Antarctica.

    In 2015, more than 38,000 tourists visited Antarctica. “These tourists are often very careful about not leaving waste or having mud. But they could carry seeds or larvae on their boots when they set foot on the Antarctic,” said Hodgson.

    More and more invasive insects and plants have been found on the Antarctic and have required removal. “the insects and plants that are native to Antarctica have survived these for thousands of years,” said Hodgson. “We have got to act now if we want to save the environment.”

    It sounds almost too good to be true, but a new study on sleeping brains suggests that listening to languages while you sleep can actually help you to learn them.

    For the study, researchers played recordings of foreign words and their translations to subjects enjoying slow-wave sleep, a stage when a person has little consciousness of their environment. To ensure that the results were not compromised by foreign language words that subjects may have had some contact with at some point in their waking lives, researchers made up totally nonexistent foreign words.

    When the subjects woke up, they were presented with the made-up words again without their translations. The subjects were then asked to imagine whether this made-up word indicated an object that was either smaller or larger. This vague(模糊的)way of testing their understanding of the words is an approach that is supposed to tap into the unconscious memory.

    Unbelievably, the subjects were able to correctly classify the words in this way at an accuracy rate that was 10 percent higher than random chance. That's not a rate high enough to have them suddenly communicating in a foreign tongue, but it is enough to suggest that the brain is still absorbing information on some level, even during sleep.

    Researchers have long known that sleep is important for memory, but previously its role in memory was thought to relate only to the preservation and organization of memories acquired during wakefulness. This is the first time that memory formation has been shown to be active during sleep.

    In other words, our brains are listening to the world, and learning about it, even when our conscious selves are not present.

    The next step for researchers will be to see if new information can be 1earned quicker during wakefulness if it was already presented during sleep. If so, it could forever change how we train our brains to learn new things. Sleep learning might become a widespread practice.

    Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claw s ( 爪) on its wings when young. They build their homes about 4.6m above the river, an important feature for the safety of the young. It is called the hoatzin.

    In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.

    Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak (喙), they can climb about in the bushes, looking very much like primitive (远古的) birds must have done. When the young hoatzins have learned to fly, they lose their claws.

    During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.
