In a surprising discovery about where higher life can survive, scientists have found a shrimp —— like creature and a jellyfish swimming beneath an Antarctic ice sheet.
About 180 meters below the ice where no light can get through, scientists had thought nothing much more than a few microbes (微生物) could exist.
That’s why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica. A curious shrimp – like creature came swimming by and then parked itself on the camera’s cable. Scientists also pulled up a tentacle (触须) they believe came from a jellyfish.
“We were operating on the presumption that nothing’s there.” Said NASA ice scientist Robert Bindschadler. “It was a shrimp you’d enjoy having on your plate.”
“We were just gaga (狂热的) over it,” he said of the 7.5cm long, orange creature starring in their two – minute video. Technically, it’s not a shrimp. It’s a Lyssianasid amphipod, which is distantly related to the shrimp.
The video is likely to inspire experts to rethink what they know about life in harsh environments. And it has scientists thinking that if shrimp – like creatures can live below 180 meters of Antarctic ice in freezing dark water, what about other cold places? What about Europa, a frozen moon of Jupiter?
Cynan Ellis – Evans, a scientist of the British Antarctic Survey called the finding fascinating. He said it was possible the creatures swam in from far away and don’t live there permanently.
But Kim, who is a co-author of the study, doubts it. “The site in West Antarctica is at least 19 km from open seas. Bindschadler drilled a 20 cm – wide hole and was looking at a tiny amount of water. That means it’s unlikely that two creatures swam from great distances and were captured randomly in that small of an area,” she said.
Yet scientist were puzzled at what the food source would be for these creatures. While some microbes can make their own food out of chemicals in the ocean, complex life like the shrimp can’t, Kim said.
“So how do they survive? That’s the key question.” Kim Sai.
“It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything.” Kim said.
1. What does the underlined word “harsh” probably mean?
A. cold B. loud C. cruel D. ugly
2. According to Kim, the shrimp – like creature ________.
A. swam great distances to Antarctic B. has always lived in the region
C. gradually evolved from shrimps D. has nothing in common with shrimps
3. The finding is significant in that ________.
A. it marks NASA’S first Antarctic biological study
B. it proves there is marine life in the Antarctic
C. it could inspire further study of life in harsh environments
D. it shows that Lyssianasid amphipod is closely related to shrimps
4. Which of the following statements about the discovery is FALSE?

B. Scientists saw two creatures in the two – minute video.
C. It is possible for creatures to live 180 meters below the ice though there is no light.

Life’s coincidences (巧合) can be good or bad, but they always surprise us. I moved to Anderson in 2004 from a small town in New York. One day I stopped at a red light and was behind a car with a license plate that read “Pearl Harbor Survivor”. My father was a Pearl Harbor survivor, so I jumped out of my truck and tapped to his window. He rolled the window down and I asked if he was a Pearl Harbor survivor.
“Yes,” he said. The lights turned green so I got back in my truck, turned left and went home straight. Then, I said to myself, “Why didn’t I get his name and phone number?” I went to the local Legion Post and asked if there was a Pearl Harbor survivor here on their roster (花名册). They told me yes and his name was Bronsil Metz. I looked up his name in the phone book and gave him a call. However, I failed to reach him anyway. I then drove to his address. With no answer to the door, I left a note saying that I would like to speak with him.
The next day Metz called me back and we arranged to meet at his house. I gathered my father’s picture albums and drove to his house the next morning. My father passed away years ago, so I was filled with excitement about talking to someone with similar experiences. We two went through the albums. As I turned the pages, he started pointing out the people he knew as well as those familiar buildings. My father was a great record keeper, so after Metz named people in some pictures, I took the photos out and on the back, in my father’s handwriting, were the names, substantiating that Metz did really know the people. At that moment, I was stunned (愣住) .

For some people, higher education is not just a goal in life, but also an expectation. In the United States, if your parents attended a college or university, there is a good chance that you will, too. Even if your parents did not go to college, you still have a good chance of completing higher education if your family is wealthy.
But your chances are reduced if you come from a needy family, a community with limited educational resources or you simply have no one to follow as an example.
Helping those in need is one of the main ideas behind a strategy of behavioral science called nudge theory or nudging. Nudging is a way of changing people's behavior through indirect suggestion and by supporting positive actions.
A growing number of U.S. colleges and universities look to nudging as a way to support poor, minority and first-generation students. They also are using it to increase overall graduation rates. Two common forms of nudging are emails to students and text messages to their mobile phones. Schools and other educational organizations keep in contact with students this way, offering advice and help when needed.
However, Alejandra Acosta — a higher education policy expert at New America — notes that there are several qualities a nudge campaign must possess in order to be successful.
Acosta says messages must be timely, meaning they reach college students well before the date by which a student is required to take action. Additionally nudges should be written clearly and provide as much information as possible. If students start to struggle in class, school officials should not just message them, saying they should seek academic support. The message should give information about what kinds of support the college or university offers and exactly how the student can make use of them. That is why nudges should possess interactive qualities, Acosta says. For example, students should be able to ask questions of school officials or be directed to a website for more information. In addition, colleges and universities must ensure their support services are in place and working as best they can.
When nudges work, they can do a lot of good. In 2018, a nonprofit group launched a nudging campaign at four U.S. community colleges. They worked with nearly 10.000 first-year students at three such colleges in Ohio and one in Virginia. A recent study found that older and minority students who agreed to receive these nudges were 16 to 20 percent more likely to continue into their second year than those who did not.
1.Who is most likely to receive and complete higher education according to the passage?
A.Tony, whose father is the only bread-winner in the family.
B.Jimmy, whose mother is a worker in a small factory.
C.Betty, whose grandmother is a housemaid of a famous university professor.
D.Cathy, whose parents failed to attend college but succeeded in starting a big company.
2.What can we know about nudging?
A.It is rooted in psychological science.
B.It is a way to improve people’s mind.
C.It offers concrete and direct advice.
D.It helps students via emails and text messages.
3.What is the passage mainly talking about?
A.The problem with higher education.
B.A way for colleges to support students.
C.The popularity of nudging campaign.
D.A national campaign dealing with poverty.

When you watch TV programs about wild animals, it is surprising to see how an antelope can escape a lion’s attack. In the wilderness, everyone has a stunt. Even plants have their own ways of fighting off enemies.
Over millions of years of evolution, plants have developed a unique defence system. Chemicals are wildly used for survival. By making their leaves, flowers, roots and fruits distasteful or poisonous(有毒的) to enemies, plants can fight back.
One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree’s leaves, the amount of poison increases in the other leaves. “It’s like the damaged leaves telephoning the others telling them to fight together against the enemy, ” he said.
The tree also sends defence messages to neighboring plants by giving out a special smell. Golden Wattle trees in the surrounding 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees’ leaves, it will die.
Every species of plant or tree is good at the production of a particular set of chemicals. A herbivore that can safely eat the leaves of one tree may be poisoned by its neighbor.
In this way, plants have developed not only individual defence system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest.
1. Which of the following can be the best title of the passage?
A.Plants Fight back with Poisons |
B.Plants Can Kill Animals |
C.Animals and Plants |
D.Lions and Antelopes |
2.According to the study, if one Golden Wattle tree is attacked by animals, it can________.
A.tell other trees to protect it |
B.produce more poison within 10 minutes |
C.send defence messages to the neighboring plants |
D.kill the animals with its leaves |
3. In this passage the underlined word “herbivore” probably means animals which ________.
A.live on both animals and plants | B.feed on smaller animals |
C.live on trees | D.feed on plants or grass |
4.The last paragraph of the passage suggests that this kind of defence system________.
A.does great harm to the animals | B.does good to the forests |
C.is helpful to some animals | D.harms the forests |
