Living in the wild can be hard. Finding food and staying safe aren't easy. Each day, animals struggle to survive in their habitats. Not all animals get by on their own. Some animals form a close partnership with other kinds of animals. These pairings are called symbiotic (共生的) relationships.

    In a symbiotic relationship, the animals depend on each other. One animal helps the other meet its needs. Sounds good, right? Not always. Some animals are not very kind to their partners. In some cases, one animal meets its needs but hurts its partner. Take ticks, for example. These insects suck blood to live. To get blood, they attach themselves to other kinds of animals. Ticks can pass germs that cause disease instead of helping their hosts.

    In other relationships, animals don't treat their partners so poorly Both animals benefit from living with the other animal.

    Small animals called cleaner shrimps have found a way of helping fish at coral reefs. As their name suggests, the shrimps clean the fish. They hang out at what scientists call a cleaning station. A fish stops by. Then a shrimp climbs onto the fish and even steps into the fish's mouth. The shrimp uses its tiny claws to pick stuff off the fish's body. That can include dead skin, tiny pieces of food, and wee creatures that can hurt the fish. The fish gets a nice cleaning. The shrimp enjoys a tasty meal offish trash.

    Small birds called plovers are also in the cleaning business. They have big customers—crocodiles. Crocs have long snouts（鼻子）filled with sharp teeth, Cleaning them is tricky. When a croc opens its mouth, the plover hops right in. The croc does not snap its snout shut. Instead, it lets the plover eat small, harmful animals attached to its teeth. The plover gets an easy meal while the croc gets clean teeth.

    At heart, parents always wish the best for their children, and they work hard for that. Nowadays, we see parents deciding the schools for their little ones before the baby is even born. Once kids starts going to school, some parents want to have a time-to-time update(最新的情况) of their kid's activities. They want to come to their classroom every day, keep an eye on whom they talk to, know the friends they keep, start telling them how to do their jobs, and keep talking to them about everything under the sun. Besides, they send their kids to extra hobby classes, as they want their children to do best in every field.

    When it comes to the education, super mum and dad have all the plans made for their children, and I am sure that they have come up with the best. So, try to fight for the dreams that your parents have seen for you. However, in some cases, it may happen that the kids have some different dreams. Parents sometimes don't even consider the choices of their kids and may force them to do what they wanted to do in life. It's good to plan the future for the children, but leave at least some decisions to them.

    So what should the children do? First, hear out all the plans that your parents have made for you. If you have some different ideas, then sit down and talk to your family about it. Be patient and respect their decisions, but put your plan forth, and make them understand what you want to do and why. Many times, you don't know the difficulties that you may have to face while pursuing your dreams. Ask your parents for suggestions, which will make them feel good and involved. That way, they may support you if you are going on the right path.

    He was the baby with no name. Found and taken from the north Atlantic 6 days after the sinking of the Titanic in 1912, his tiny body so moved the salvage (救援) workers that they called him “our baby.” In their home port of Halifax, Nova Scotia, people collected money for a headstone in front of the baby's grave (墓), carved with the words: “To the memory of an unknown child.” He has rested there ever since.

    But history has a way of uncovering its secrets. On Nov. 5, this year, three members of a family from Finland arrived at Halifax and laid fresh flowers at the grave. “This is our baby,” says Magda Schleifer, 68, a banker. She grew up hearing stories about a great-aunt named Maria Panula,42, who had sailed on the Titanic for America to be reunited with her husband. According to the information Mrs. Schleifer had gathered, Panula gave up her seat on a lifeboat to search for her five children -- including a 13-month-old boy named Eino from whom she had become separated during the final minutes of the crossing. "We thought they were all lost in the sea," says Schleifer.

    Now, using teeth and bone pieces taken from the baby's grave, scientists have compared the DNA from the Unknown Child with those collected from members of five families who lost relatives on the Titanic and never recovered the bodies. The result of the test points only to one possible person: young Eino. Now, the family sees no need for a new grave. "He belongs to the people of Halifax," says Schleifer, "They've taken care of him for 90 years."

    Everything was put neatly into my suitcase．I'm a flight attendant．I'm so organized，my half of the closet could be a display at The Container Store．My husband's half of the closet？Just thinking about it made my head ache．I carried my suitcase downstairs．Bill was in the kitchen cooking．Looking at the messy kitchen，I shouted，“Why do you have to be so messy？” Bill looked hurt，“What？” I sighed and left for the airport．

    On my last flight，an elderly couple had the seats in my section．They held hands during takeoff．Later I caught them looking into each other's eyes．Something about that look was familiar．Then I realized：it was the look Bill and I had worn in our wedding photographs．I couldn't resist asking them about the secret of their long-lasting marriage. “Have fun together，”the man said, “and never take each other for granted．”

    His words circled in my head long after we landed．Bill wasn't perfect．But then，was I？I kept complaining about his messiness and forgot his kindness，his ability to see the bright side of every situation-qualities that ran so much deeper，the reasons I had married him in the first place

    I took out my cell phone and called Bill. “I miss you already.” I said．“I miss you too，Kim，” he said．As soon as my flights were over，I rushed home．Bill met me at the door．"I have a surprise for you．"he said and led me into the kitchen．I glanced around the room．He really had worked hard．In spite of the fingerprints on that microwave floor，I could see our reflection in it：my husband and I，our smiles glowing with love for each other，just like in our wedding photos．

    A scientist working at her lab bench and a six-old baby playing with his food might seem to have little in common. After all, the scientist is engaged in serious research to uncover the very nature of the physical world, and the baby is, well, just playing…right? Perhaps, but some developmental psychologists have argued that this "play" is more like a scientific investigation than one might think.

Take a closer look at the baby playing at the table. Each time the bowl of rice is pushed over the table edge, it falls in the ground—and, in the process, it belongs out important evidence about how physical objects interact; bowls of rice do not flood in mid-sit, but require support to remain stable. It is likely that babies are not born knowing the basic fact of the universe; nor are they ever clearly taught it. Instead, babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact. Though their ranges and tools differ, the baby's investigation and the scientist's experiment appear to share the same aim(to learn about the natural world ), overall approach (gathering direct evidence from the world), and logic (are my observations what I expected?).

Some psychologists suggest that young children learn about more than just the physical world in this way—that they investigate human psychology and the rules of language using similar means. For example, it may only be through repeated experiments, evidence gathering, and finally overturning a theory, that a baby will come to accept the idea that other people can have different views and desires from what he or she has, for example, unlike the child, Mommy actually doesn't like Dove chocolate.

Viewing childhood development as a scientific investigation throws on how children learn, but it also offers an inspiring look at science and scientists. Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort —the desire to explore, explain, and understand our world—is simply something that comes from our babyhood. Perhaps evolution provided human babies with curiosity and a natural drive to explain their worlds, and adult scientists simply make use of the same drive that served them as children. The same cognitive systems that make young children feel good about feel good about figuring something out may have been adopted by adult scientists. As some psychologists put it, "It is not that children are little scientists but that scientists are big children."
