    Many science fiction stories tell about explorers arriving in a new world. The explorers then use some kind of high-tech device to test for breathable air or signs of life. But here on Earth, science fiction is becoming reality through a new sampling technology called environmental DNA, or eDNA for short. Scientists can use it to identify rare species or estimate fish populations with just a little air or water.

    Environmental DNA can be used in two ways. One is to identify the creatures that live in a certain place. The other is to confirm the presence or lack of a specific creature.

    Caren Goldberg is one of the first biologists to take the technology from the testing stage to actually using it. She sees eDNA as a way to get answers more efficiently and with less destruction compared to traditional survey techniques. Until recently, scientists depended on snorkeling ( 潜水), netting or using an electric current to temporarily catch fish.

    This newer way to identify what lives in the environment is becoming popular around the world. Animal experts in Vietnam are using the eDNA to find the last, wild Yangtze giant softshell turtles. One researcher on the Caribbean island of Trinidad is using the sampling technology to find endangered golden treefrogs. In Madagascar, it is being used to identify amphibian(两栖动物)diseases.

    Ms Goldberg has used eDNA testing to confirm the local extinction (灭绝) of a leopard frog in the American state of Idaho. She has also been asked to document the spread of the New Zealand mudsnail in the state of Washington. The creature has been found in lakes and other waterways across the state.

    Scientists working with the technology say they do not expect robots to replace field biologists anytime soon. But the old-fashioned field work could soon be more targeted.

(1)、Compared to traditional survey techniques, eDNA is more______.
A、complex B、eco-friendly C、dangerous D、convincing
(2)、By using eDNA, Caren Goldberg has______.
A、succeeded in catching many fishes B、found the existence of golden treefrogs C、documented the spread of softshell turtles D、confirmed the disappearance of the leopard frog in Idaho
(3)、What can we infer from the last paragraph?
A、Robots will replace scientists soon. B、Some scientists are against using eDNA. C、The old-fashioned field work may disappear. D、Many biologists are unwilling to do the field work.
(4)、What is the best title for the text?
A、Science Fiction Becomes Reality for Species Surveys B、Biologists Explore Space with the Help of eDNA C、Scientists Found Methods to Test for Signs of Life D、New Technologies Are Presented in Science Fictions
举一反三

    In the spring of my career, I found myself questioning the choice of my life's work. The students did not appear to be motivated; the paperwork was overwhelming (巨大的) and the constant changes of educational direction were discouraging. But I just could not bring myself to do anything else. “Next year,” I would say, “next year I will switch jobs, make more money and have far less stress.” Next year just never came. I am now in my forties. And while I am no longer in the classroom or at the schoolhouse, I remain an educator. It finally dawns on me that there is no other profession that will let me change children's minds and have an impact on their future. For every student that finally “got it”, for every new teacher that said, “You inspired me to stay,” I get the raise that has never quite made it to my paycheck.

    I was on a plane recently and the flight attendant asked my name. When I told him, he said, “I knew that was you! You taught at my elementary school. You made me take my cap off in the building and told me I was handsome.” He then paused and said, “I think I kept my hat on until you saw me, just so I could get that compliment (赞美). Thank you for making me feel special.”

    We have now entered an age where nothing is private and secrets are hard to keep. Your “friends” are counted by simply clicking a button. Face-to-face interactions are seen by many as unnecessary and time-consuming. Of course, we can do anything online, including teaching and learning. But I guess I am just old school. I want to look into your eyes when the answer finally dawns on you.

    In the depths of the French Guianese rainforest, there still remain unusual groups of indigenous(土著的)people. Surprisingly, these people live largely by their own laws and their own social customs. And yet, people in this area are in fact French citizens because it has been a colony of the French Republic since 1946. In theory, they should live by the French law. However, their remote locations mean that the French law is often ignored or unknown, thus making them into an interesting area of “lawlessness” in the world.

    The lives of these people have finally been recorded thanks to the effects of a Frenchman form Paris called Gin. Gin spent five months in early 2015 exploring the most remote corners of this area, which sits on the edge of the Amazon rainforest, with half its population of only 250,000 living in its capital, Cayenne.

    “I have a special love for the French Guianese people. I have worked there on and off for almost ten years,” says Gin. “I've been able to keep firm friendships with them. Thus I have been allowed to gain access to their living environment. I don't see it as a lawless land. But rather I see it as an area of freedom.”

    “I wanted to show the audience a photographic record touching upon the uncivilized life,” continues Gin. “I prefer to work in black and white, which allows me to show different specific worlds more clearly.”

    His black-and-white pictures present a world almost lost in time. These pictures show people seemingly pushed into a world that they were unprepared for. These local citizens now have to balance their traditional self-supporting hunting lifestyle with the lifestyle offered by the modern French Republic, which brings with it not only necessary state welfare, but also alcoholism, betrayal and even suicide.

    By now you've probably heard about the "you're not special" speech, when English teacher David McCullough told graduating seniors at Wellesley High School: "Do not get the idea you're anything special, because you're not." Mothers and fathers present at the ceremony 一 and a whole lot of other parents across the Internet — took issue with McCullough's ego-puncturing (伤自尊的) words. But lost in the uproar (喧嚣)was something we really should be taking to heart: our young people actually have no idea whether they're particularly talented or accomplished or not. In our eagerness to elevate their self-esteem, we forgot to teach them how to realistically assess their own abilities, a crucial requirement for getting better at anything from math to music to sports. In fact, it's not just privileged high-school students: we all tend to view ourselves as above average.

    Such inflated self-judgments have been found in study after study and it's often exactly when we're least competent at a given task that we rate our performance most generously, in a 2006 study published in the journal Medical Education, for example, medical students who scored the lowest on an essay test were the most charitable in their self evaluations, while high-scoring students judged themselves much more strictly. Poor students, the authors note, "lack insight" into their own inadequacy. Why should this be? Another study, led by Cornell University psychologist David Dunning, offers an enlightening explanation. People who are incompetent, he writes with coauthor Justin Kruger, suffer from a “dual burden": they're not good at what they do, and their very clumsiness prevents them from recognizing how bad they are.

    In Dunning and Kruger's study, subjects scoring at the bottom on tests of logic, grammar and humor -extremely overestimated'' their talents. Although their test scores put them in the 12th percentile (百分位数) they guessed they were in the 62nd. What these individuals lacked (in addition 9 clear logic, proper grammar and a sense of humor) was "meta cognitive skill" the capacity to monitor how well they're performing. In the absence of that capacity, the subjects arrived at an overly hopeful view of their own abilities. There's a paradox here, the authors note: The skills that lead to competence in a particular domain are often the very same skills necessary to evaluate competence in that field? In other words, to get better at judging how well we're doing at an activity, we have to get better at the activity itself.

    There are a couple of ways out of this double bind. First, we can learn to make honest comparisons with others. Train yourself to recognize excellence, even when you yourself don't possess it, and compare what you can do against what truly excellent individuals are able to accomplish. Second, seek out feedback that is frequent, accurate and specific. Find a critic who will tell you not only how poorly you're doing, but just what it is that you're doing wrong. As Dunning and Kruger note, success indicates to us that everything went right, but failure is more ambiguous: any number of things could have gone wrong. Use this external feedback to figure out exactly where and when you screwed up.

    If we adopt these strategies — and most importantly, teach them to our children — they won't need parents, or a commencement (毕业典礼)speaker, to tell them that they're special. They'll already know that they are, or have a plan to get that way.

I love hiking. In the mountains, the birds sing for me; the various trees and flowers overwhelm (征服) my eyes and the deep blue of the sky inspires me and makes me feel calm. Furthermore, I can breathe the fresh air, keeping away from the dust and pollution of the city. It seems that all my senses are awakened when I am in the mountains. More importantly, hiking teaches me a lot.

I have been a traveler since childhood and was drawn towards mountains and their beauty. Later my reading several travel books made me think if I could also go on such journeys. Finally, I decided to give it a try. After I was well-prepared to face all difficulties of the hike, I joined a group of hikers. On the way, we encouraged each other, took beautiful pictures, and sat down now and then to feel the breath of the land. All my worries disappeared and we talked and laughed just like kids. This journey excited me for a long time.

I never actually realized the need for water until I started hiking. I remember once I was on a hike where our water was not enough. It was a night hike and the next day we had to return back to our base camp following the same route. So we have to save it for emergencies (紧急事件).That day I exactly learned water is of great value and that we have a duty to save it.

Besides enjoying the beautiful natural views, you have to go out of your comfort zone and push yourself hard to challenge your normal limits when hiking. On a hike, you may sometimes get injured but you can't stop until you reach the destination. Every next try will surely make you stronger and happier if you embrace (拥抱) your injuries, pains and discomforts.

Sometimes we may have a conversation with those locals living in wooden houses. You know, mountain life is hard and difficult. But they never complain about their life. They are happy with what they have. Many times they are facing extreme weather and they just fight with them. They are so brave. What can we complain about?
